Growing green onions in a greenhouse all year round. How to effectively grow onions on a feather in a greenhouse

Greens, especially onions, are a beautiful ingredient in any dish: on New Year's Eve - it turns into a Christmas tree, and by March 8 it becomes tulip stalks, they are tied with "bags" of pancakes and meat filling that are beloved by many. In a word, this plant becomes an indispensable assistant to housewives. In order for it to please all year round, it is necessary to grow onions for greens in a greenhouse.

Green onions have the ability to improve digestion and the process of assimilation of food taken with it. This is not the whole list of the positive effects of this vegetable on the body, but even without knowing this, the desire of people in winter and summer becomes clear.

Greenery is a product that is relevant and in demand at any time of the year, but at the same time unpretentious in greenhouse cultivation.

If everything is much simpler with planting in the summer - you can plant it on a personal plot, then in winter you will need a greenhouse to get a crop.

For growing onions in a greenhouse, structures made of various materials are used:

polycarbonate;
glass;
film.

The choice of coverage most often rests on finances. The cheapest option is film, but it should be noted that it will need to be replaced every year, so is it so cheap? On the other hand, saving on coverage in the first year will make it possible to purchase the necessary tools and equip the premises. Of the inconveniences in this coating is the annual installation / dismantling.

Long term growing green onions in a greenhouse best material become polycarbonate. The main advantages of this material:

reduction of heat loss, which means a reduction in heating costs;
decent strength;
structural durability.

As for the placement site, it should be protected from the wind, the best location is south.

The greenhouse must be equipped with the following:

a workable heating system, if landing for the winter is planned;
lighting system (preferably vertical lamps);
boxes with soil or beds.

Where to plant? There are several options. You can plant directly into the ground, but in this way there is an irrational use of the area. The best option would be - the construction of shelving. In addition, shelving saves the gardener from several tasks:

on racks, the soil warms up faster, as a result, the growth period is reduced by 12-15 days on average;
the construction of racks saves a person from having to bend his back and crawl on his knees;
for watering plants, less water is required, and this is already saving;
when constructing several-tier racks, the landing area automatically increases.

When equipping the racks, do not forget to use last year's film, put it on the base and pour earth into it.

Be sure to organize heating, especially along those walls of the greenhouse that will not receive sunlight.

Plants will need lighting in winter and in cloudy weather. If onions will be grown on racks, then to illuminate the lower tiers, it is necessary to use fluorescent lamps, since it is on them that plants experience a lack of light.

By and large, now the greenhouse is ready.

Which variety to choose?

Growing onions for greens in a greenhouse is quite a profitable business, but in order to get good harvest, you need not only to create conditions for the growth of the plant, but also to choose the right variety. It should be noted that there are several types of onions grown on greens:

onion;
batun;
slime;
chives;
tiered bow.

Bow-batun. This plant belongs to the category of perennials. The harvest period lasts from early spring to late autumn. Its peculiarity is that it does not form bulbs. The greens of this plant are similar to the greens of the onion. It tolerates winter well. Its landing is better to start in December.

In this species, the following are considered the best varieties:

Gribovsky-21;
salad-35;
Local Ural;
May 7

Slime. The plant is milder in taste than onions, has a garlic flavor. It tolerates cold and frost well, loves humidity. Planting of this type can be done at any time of the year - this is its advantage.

Schnitt. This species is also perennial, but is more suitable for open ground, as it is frost-resistant.

The best varieties:

Pink K-1669;
Siberian K-1670.

Multi-tiered onions are the most suitable species for growing in the autumn-winter period in a greenhouse. The best varieties: Gribovsky-38, Odessa winter 12.

Onion. Most often, gardeners choose this particular species for growing greens in a greenhouse. Multi-germ varieties are selected that are able to form more leaves.

The best varieties of this species:

Stuttgarter Riesen;
Strigunovsky local;
Bessonovsky fruitful;
Danilovsky 301

Landing and care

Growing onions in a greenhouse takes place all year round, but it is best to produce them from October to May. The soil is prepared in advance, it must be fertile and loose. Almost all crops love fertilized soil. Before planting, it is advised to add the following fertilizer to the soil mixture, the calculation is per 1 sq.m.:

manure - 1 bucket;
superphosphate - 30g;
potassium chloride - 15g.

Onions in a greenhouse are planted in three ways: using heads, seeds or seedlings.

If planting is done with bulbs, then in October the planting material is located in boxes at a distance of one centimeter from each other. If planting occurs in early spring, then the distance between seedlings for growing is increased to five to eight centimeters.

Planting seedlings is carried out in early March. Initially, seeds are prepared: they are soaked either for three days in water at room temperature, or placed for 8 hours in water with a temperature of + 40 ° C. Next, the seeds are sown in prepared containers. Seedlings can be planted in a greenhouse no earlier than two months after germination.

Each type of onion has its own planting technology.

So, batun can be grown with seedlings and seeds, starting in December. Sowing is carried out densely: 3g is used per 1 sq.m. site. Resorting to the seedling method, grow five plants in a container, which are then planted in such groups at a distance of 15 cm from each other. For the purpose of one-year forcing during harvesting, green leaves are pulled out along with an underdeveloped bulb, otherwise only greens are cut off. It should be noted that three-year-old bulbs are fast-bearing.

Slime onions are grown in three ways: dividing the bulbs, seeds or seedlings. After it must be poured with warm water.

Onions have been grown in the greenhouse since the end of November. Harvest can be harvested in this case after 30 days. Secret delicious greens of this plant in planting - the soil for planting should be with neutral acidity, as well as sufficiently moist. We can say that this species is quite fertile, can yield up to 5 times per season.

Onion care is quite simple, this plant is not demanding. All it takes is:

feed the plant 1 time during the entire growth period, using a solution ammonium nitrate at the rate of 30g per bucket of water;
abundant watering, onions are very fond of water;
control the level of soil moisture, prevent rotting of the bulb;
observe the temperature regime, especially in winter (not lower than + 19 ° C during the day and not less than + 12 ° C at night);
prevent drafts in the greenhouse;
prevent plant diseases (onion mosaic, black mold, onion fly, tobacco thrips, etc.)

Experienced gardeners claim that if the onion is fed a week after planting, and then 10 days after the first feeding, then it will yield much more. The following mixture is offered as a fertilizer:

water - 1 bucket;
ammonium nitrate - 15-20g;
superphosphate - 30g;
- 15-20g.

Green onions in the greenhouse must be cut in time. The average is a sheet length of 30 cm.

Features of growing for sale

The main secret in growing onions for sale is right choice planting material. Selection rules to be followed for a successful outcome:

it is worth choosing early or mid-season varieties;
for sprouting onions on greens for the purpose of subsequent sale, the best is sevok (two-year-old);
it is unacceptable with an open "neck", such a vegetable affects rot;
if the bulb's root buds are already swollen, this material is very good for planting;
when growing onions for sale, it is better to equip the greenhouse with multi-tiered racks, thereby increasing the planting area.
if germination will come from different "batch" and varieties, then it is better to check the growth rate in order to avoid an extra crop that will be lost.

Green onions are a unique product that has a large amount of useful substances and vitamins. In addition, it serves as an excellent decoration for various dishes. Therefore, it is in great demand at any time of the year. Many housewives are engaged in growing bulbs on a feather using improvised means.

L and other features are indicated in the article.

For these purposes, they plant onions in jars, which are then placed on the windowsill. Thus, they will be able to provide vitamins to their entire family and save on the purchase of a finished product. But you can also grow onions in a greenhouse. There is nothing complicated here, it is important to observe elementary agricultural technology.

to get a high result and the onion actively grew on a feather in winter, it is necessary to maintain optimal conditions for greenery to grow. Since onion growth will occur in a greenhouse, the temperature should be 18-20 degrees in daytime.

At night, it is also worth adhering to the air temperature. It will be 14-15 degrees. When the bed has been planted, it is worth covering it with a film. It must be kept until new shoots appear.

Agrotechnics of feather onions involves timely watering. For these purposes, it is worth using a warm settled liquid. In this case, it is important to prevent the formation of cracks on the soil surface. To eliminate this, it is important to periodically loosen the earth and remove existing weeds.

On the video - growing onions on a feather in a greenhouse in winter:

Also, for a quality crop in the greenhouse, there should be no drafts. If this condition is not met, then the plants will grow weakly, and may get sick. If you follow these recommendations, then your work will not be in vain. As a reward, you will receive delicious and beautiful onion feathers. Harvesting can be done within 5-10 days from the date of planting.

How it happens is indicated in the article.

Also in the greenhouse it is worth taking care of heating. For these purposes, electric or gas boilers are used. From them, pipes lead evenly and are distributed around the entire perimeter of the room. With the help of lighting, you can increase the length of daylight hours. In this case, you can not do without lamps and fluorescent lights. They should be placed evenly inside the greenhouse.

It is worth carrying out irrigation in the greenhouse using an automatic or mechanical method. If the greenhouse is large, then to save time and effort, you need to use automatic systems glaze.

On the video - the technology of growing onions in a greenhouse:

To set up automation, you should use a specific instruction. Subject to all recommendations and rules, the connection is made electrical system. Thanks to automatic irrigation, you can not waste time on watering and at the same time be sure of its quality.

Growing features

Before you start growing a crop, it is important to choose the right planting material. If you are going to grow in a greenhouse all year round, then you need to use the following varieties:

chives;
shallot;
leek;
onion - slime;
Canadian or Egyptian bow.

The presented onion variety is in great demand among many farmers. The reason for this success is that the variety is unpretentious in care, can withstand frost and at the same time give high yields. In the role of planting material, bulbs are used, the size of which is up to 4 cm, as well as air bulbs.

Before planting a crop, it is necessary to carefully prepare the planting material. To do this, it is worth sorting and discarding bad bulbs. Also cut off the top half of the onion. Such activities are necessary in order to deliver oxygen to the kidneys. Thus, they will begin to grow faster. This process is characterized by its length and complexity. But doing it is extremely necessary if your goal is to get a high yield.

This completes the preparations. To increase the germination of the crop, it is worth soaking the bulbs in warm water. Its temperature regime should be 36-38 degrees. If you soak the bulbs in cold water, then you will not get a positive result. Soaking time - 12 hours.

After carrying out all the preparatory activities, you can proceed to the landing. To do this, you need to use special boxes with soil. The landing method is bridge. It involves the use of one box with an area of 0.25 m2 and 2-3 kg of planting material. To avoid the formation of mold on the soil surface, it is worth using lime. Sprinkle it on top of the ground. The boxes are installed tightly to each other on the racks. To get seedlings in a greenhouse, it is worth maintaining the temperature at 18-20 degrees.

After 12-14 days, the onion forms a strong root system and a feather will appear. Its length will reach 5-8 cm. After that, the culture is subjected to thorough watering and the temperature is raised to 22 degrees. After a few days, mineral fertilizers can be placed in the boxes. In this case, nitrogen and potassium are used. For 1 m2 there are 40 ammonium nitrate and 15 g of potassium chloride.

Green onions can grow in any soil. The exception is sandy and stone ground. The quality of the soil depends on the amount of mineral fertilizers that are located in the soil.
Before planting this crop in 2 days, it is worth fertilizing the soil with natural fertilizers. Wood shavings must be added to keep the soil moist. It will not only plow the ground, but also prevent moisture from completely evaporating.

Harvesting is allowed after the length of the feather has reached 35 cm. Trimming is done in such a way that the lower part of the feather is clean and not very thin. Stretch film is used as packaging. The formation of beams is performed from 1 g of onion. It is this packaging that is considered the most popular among wholesale buyers.

Green onion is a very popular plant. It is not only simply consumed in its pure form, but also used to decorate individual dishes. In order not to spend money on buying onions, it is better to grow them at home. To obtain high yields, you should not only choose the right variety, but also create the necessary conditions in the greenhouse.

Nowadays, you won’t surprise anyone with onions, but not a single culinary specialist can do without him. In ancient Egypt, onions were used for 3 thousand years BC. e. The ancient Greek historian Herodotus, who was born 25 centuries ago, quoted an inscription carved on the pyramid of Cheops: “1600 talents of silver were spent on radishes, onions and garlic to feed the slaves.” In the Middle Ages, the bow was an indispensable component of the provision of noble knights during the Crusades. For eight bulbs, the French exchanged each of their captured compatriots with the Saracens. 5 thousand years have passed since India and China learned to grow winter onions. The cultivation of onions in the territory of modern Europe was mentioned in his treatise "Natural History" by the ancient polymath Pliny, who lived in the 1st century AD.

Currently, more than 2 thousand are grown in the world.

The diameter of the bulbs can reach up to 15 cm. The external dry scales of different varieties are red, white, golden yellow, purple, light brown.

Under the outer ones are fleshy and juicy inner scales, most often white, in some varieties - greenish, pinkish or purple. Onion scales are attached to the bottom, which is a shortened stem. On this very bottom, in the axils of juicy scales, buds develop, from which daughter bulbs grow. By their number, they judge multi-germ, or in other words, the nesting of the variety.

Multi-germ (poly-nesting) is a varietal trait of onions. Varieties that form 1-2 bulbs are called low-buds, medium-sized ones form up to 4 new bulbs in the nest, 5 or more (sometimes this figure reaches 25) emerging bulbs characterize the variety as multi-germ. Varieties belonging to the latter category are highly valued by those who grow green winter onions in greenhouses and know the value of every centimeter of land used in it.

According to taste characteristics, onion varieties are divided into spicy, semi-sharp and sweet.

Spicy varieties contain more dry matter (up to 15%), essential oils(up to 155 mg / 100 g), sugars (up to 15%) and glycosides. However, we do not perceive their increased sweetness due to the burning-bitter taste of more concentrated glycosides.

Sweet varieties are distinguished by greater juiciness and a more delicate sweet taste, that is, they contain more water and less sugars, essential oils and glycosides.

Peninsular varieties occupy a middle position. Bulbs of sharp varieties are best preserved, semi-sharp varieties are slightly worse, sweet onions are stored poorly.

Sharp and semi-sharp bows are distinguished by polygamy.

According to the ripening time, onion varieties are divided into early (less than 100 days), medium early (100-110 days), mid-ripening (110-120 days) and late (more than 120 days).

Popular varieties:

Sweet onion varieties take longer to ripen, so they are grown in the southern regions of our country.

From the video you will find out which varieties of onions are the best.

Soil preparation

One of the most important components of a high yield of onions is the correct and high-quality preparation of the soil of the site where winter onions will grow.

The site must be chosen flat, open and as much as possible illuminated. The beds shaded by nearby trees will not give a high yield of onions. A very important condition for the productive cultivation of all types and varieties of onions is the absence of weeds.

It is best to plant onions after those crops under which significant doses of organic matter were applied. Good onion precursors include cucumbers, zucchini, pumpkin, beans, vegetable peas, tomatoes, green crops, early white cabbage and cauliflower.

If the area allotted for planting onions has not previously been fertilized, it is necessary to start preparing it in the fall. The earth is dug up, with rotted manure or compost in the amount of 2-4 kg per 1 m2. This will not only enrich the composition of the soil with nutrients, but also improve its structure, give friability. Simultaneously with humus, 100-200 g of wood ash are added. In the absence of organic matter, mineral fertilizers are applied. Of the nitrogen fertilizers needed by the plant for speed and strength of growth, 10-30 g of saltpeter or 20-50 g of ammonium sulfate per 1 m2 will be required.

Superphosphate is applied to form roots, accelerate the development and maturation of plants. Dosage - 30-60 g per m2.

Potassium chloride, in the amount of 10-20g per 1 m2, will ensure the accumulation of sugar in the plant and increase resistance to diseases.

The very high requirements of onions to the soil are due to the fact that the roots of this crop are very underdeveloped, most of them are located in the surface layer at a depth of 5-20 cm. At the first stage, the development and growth of the root system is much slower than the growth of the vegetative mass.

Landing

Onions are a perennial crop. But you can grow winter onions (turnips) from seeds in an annual crop. Bulbs grown in this way last much longer without sprouting.

Onion seeds are grown in several ways: early spring sowing in open ground, winter sowing and with the help of seedlings.

Using the first option, the seeds are sown in the ground as early as possible, when the snow has melted and the earth has not had time to dry out much. Seeds of early-ripening varieties are suitable for sowing, and only fresh, last year's ones, since even two years ago has a bad effect on seed germination.

Seeds must be prepared before planting. Due to the large amount of essential oils, it will take a long time for the seeds to germinate. To reduce this interval, they are soaked, wrapped in cloth, for 14-18 days. After that, the hatched seeds are placed in a weak solution of manganese for 10-12 hours (for the prevention of fungal diseases), dried to a state of flowability. Everything, the seeds are ready, you can plant.

Nigella is sown to a depth of 1-1.5 cm in rows, every 15-20 cm, or in six line ribbons, keeping the distance in the lines 15-20 cm, and between the ribbons 45-50 cm, spending seeds within - 8-10 g , on - 10 square meters of land.

Podzimny sowing of nigella is done with dry seeds, without soaking, but with pickling with potassium permanganate, as described above. Sow just before the onset of frost. The rate of planted seeds is increased by 20-25%, the sowing depth is 2-2.5 cm.

The seedling method allows you to grow sweet late-ripening onions. For this, seedlings are sown 2 months before planting.

Soil for nurseries is prepared by mixing equal parts of humus and soddy soil. The norm of seeds per 1 m2 of the area of seedling boxes is 15-20 g. The boxes should be low so as not to shade the seedlings. Seeds are soaked for 1 day before planting, changing the water several times.

The seeding depth is 1 cm. Before germination, the boxes are covered with a film to avoid drying out of the soil. Until germination, the temperature is maintained at 18-20 degrees, after which it is reduced to 14-15 in the daytime and 10-12 at night to prevent the sprouts from “stretching”.

Seedlings with a neck thickness of 3-4 mm, with 3-4 true leaves, are ready for planting. 7-10 days will be spent on hardening at temperature and conditions open ground. Seedlings are planted after 6-10 cm in a row and with a row spacing of 20-45 cm. Planting in a tape way is possible.

The rows are watered and mulched to prevent the formation of a soil crust.

When growing onions in a two-year culture, in the first year a small onion grows from the seeds - a set, in the second year a full-fledged winter onion is obtained from the set. The preparation of nigella for sowing occurs in the same way as for the onion, but it is sown more densely. The furrows are located at a distance of 10-12 cm from each other, the seed consumption is 1 g per 1 linear meter (the distance between the seeds should be approximately 1-1.5 cm). The optimal size of onion sets for planting is 2-3 g in weight and 1-1.5 cm in diameter. Larger bulbs are prone to bolting, and a large bulb will not grow from small things.

Sets are planted after 8-10 cm in a row, the step between rows is 30 cm. Small onion sets do not tolerate long storage - it dries out, so it is more expedient to plant it before winter, without waiting for the next year. The full cycle for growing turnip sevkom is 3 years. In the first year, seeds are obtained from the seed bulb, in the second year, onion sets grow from the seeds, and only in the third year does the time come when the onions are harvested in the bins.

Care

Onion planting care mainly consists of loosening and weed control. Nigella crops before germination can be covered with a transparent film, this will prevent the formation of a crust on the soil surface. At this time, watering is critical, drying out the soil can reduce seedlings by 50 - 70%. After the emergence of seedlings, they are thinned out, leaving 2 cm between plants.

Planting nigella on the bulb is thinned out 3 times - the first is carried out when the height of the sprouts is 7-10 cm, the second after 3 weeks and the third after another three weeks, achieving a distance of 10 cm between the bulbs.

All onion plantings must be fed with nitrogen fertilizers in the last decade of May, and in mid-June - with ammonium nitrate and potash fertilizers. From the end of July, onion watering stops. It remains to figure out when to harvest the onions.

Usually, onions begin to be harvested from late July to mid-August. Knowing the date of planting, varietal affiliation in terms of ripening and the simplest mathematical operations, you can accurately determine the date when to remove the onions for storage.

The external readiness of the onion for harvesting looks like this: the feather lies down, turns yellow, the neck dries up. If the onion feather continues to stand upright, it is crushed and after a few days, when the neck dries, they start harvesting.

That's when you don't need to remove the onion, so it's in rainy weather.

Diseases and pests

False powdery mildew or peronosporosis is expressed in wilting of the leaves, with further yellowing and dying off, the appearance of pale gray spots. It affects not only feathers, but also the bulb. The reason is infected planting material and non-observance of crop rotation. Onions are treated with Oxyx (20 g per 10 liters of water).

It will take 2 sprays with an interval of 2 weeks.

Gray rot can be recognized by spots on the fruit, the bulb softens, resembles a boiled one. A fungal disease that penetrates the bulb through the neck when dried. Not amenable to treatment. For prevention, you can use the drugs Switch and Quadris.

The mosaic covers the onion feathers with stripes, makes them flat, and inhibits the development of the plant. This virus is spread by aphids and mites, it cannot be cured. In order to prevent, insecticide treatment is recommended to control peddlers.

The onion fly provokes the drying of the tips of the leaves and the decay of the bulb. After its discovery, the garden bed is watered with a solution of kitchen salt (250 g per 10 liters of water), carrots repel it. Therefore, the rows of onions alternate with carrots.

Onion moth is more dangerous for planting onions on greens (its larvae feed on the juicy inside of feathers). Prevention will be a weekly sprinkling of rows with wood ash and tobacco dust.

Green onions are a storehouse of nutrients and vitamins, and just nice addition to a variety of dishes. Therefore, they love it and try to buy it at any time of the year. Housewives grow feather bulbs in jars on the windowsill in winter to provide the family with vitamins, but you can grow feather onions in a greenhouse! Moreover, this does not require mega-efforts - everything is quite simple, you just have to follow agricultural practices.

The cultivation of greenery begins with the preparation of a greenhouse and soil in the beds. It is necessary to clean the greenhouse, check the performance of the heating system - this is important if you are going to plant onions for the winter. Do not forget about the lighting system, because you will have to light up the landings, and it is better to place the lamps vertically in order to get an even, beautiful green feather.

Almost all vegetables love well-fertilized soil, which has all the necessary mineral and organic matter. The bow-feather in this regard is no exception, and he also loves light, breathable earth. Therefore, in advance you need to prepare the soil mixture for the formation of beds where they add:

compost or manure - 1 bucket per 1 sq.m.;

superphosphate - 30 g per 1 sq.m.;

Potassium chloride - 15 g per 1 sq.m.

Selection and preparation of seeds for planting onions in a greenhouse

In the event that onions are planted with seeds immediately into the soil, first you need to choose the appropriate type and varieties of onions. If you decide to grow onions, for example, then Maysky-7 and Gribovsky-21 varieties are suitable; if there is a desire to grow onions, then you can take the seeds of Strigunovsky local or Bessonovsky fruitful. After that, the seeds are washed and soaked for a day in slightly warm water.

The soil can be pre-fertilized and moistened. Planting onions in a greenhouse is as follows:

Seeds are placed in the ground no deeper than 2 cm, while it is desirable to keep the distance between them at least 1 cm.

From above it is permissible to sprinkle with a small amount of peat or humus, in this case ordinary earth is also suitable.

One of the conditions for obtaining a decent harvest in the future is top dressing. It can be produced twice during the entire period: immediately after planting or immediately before placing the seeds in the soil and 10 days later. As a fertilizer, ordinary manure, ammonium nitrate are suitable.

Both components are diluted with water in a ratio of 1:30. Some gardeners also like to add to the ground wood ash, but it is recommended to use it to enrich the soil before the crop is planted.

Onions love moisture, but an excess of water can harm them. Watering the soil is carried out with water at room temperature (approximately 25ºC) every few days as the soil dries.

Greenhouse for growing onions

If for summer period a greenhouse with a wooden frame is suitable, then for growing onions on a feather in winter conditions you will need a more solid structure with a metal frame, preferably on a concrete foundation and with a heating system. However, wooden greenhouses are also suitable for use in winter, but their service life is much shorter than metal structures.

The business of growing onions for greens can become profitable if the process takes place year-round in a heated greenhouse.

Optimal for winter greenhouses is the choice of cellular polycarbonate as a coating material, and its thickness should not be too small or large - values from 4 to 8 mm are considered the most suitable. Cellular polycarbonate of this thickness is strong enough not to break under the weight of snow, transmits sunlight well, which plants get much less in winter, and also retains heat well inside the greenhouse.

The heating system, whether stove, water or electric, will allow not only greenery, but also others vegetable crops feel comfortable in the greenhouse throughout the year. Obviously, the installation of this option is a priority, but at the same time it will have to spend additional funds.

Features of growing onions on a feather in a greenhouse

Before you start growing a crop, it is important to choose the right planting material. If you are going to grow in a greenhouse all year round, then you need to use the following varieties:

chives;

· shallot;

· leek;

onion - slime;

· Canadian or Egyptian bow.

A short description of each type will help you make the right choice.

A multi-tiered onion is considered the most profitable and unpretentious. It is quite possible to grow it in low light and relatively low temperatures. In this case, underground onions (false) and bulbs serve as seed material, 1 kg of which is capable of producing at least 2 kg of full-fledged high-quality greenery within 25-30 days.

The slime onion is a very early ripening and frost-resistant species that has become widespread in recent years. Having wide leaves with rounded ends, a delicate taste and a light garlic aroma, it looks a little like an onion. This high-yielding species is able to grow all year round, so it can be planted in a greenhouse at any time. For this, bulbs with pieces of rhizome are used. The plant is very unpretentious and does not need high temperatures.

Batun onions, in comparison with onions, have more even greens and a fairly low cost. Therefore, the forcing of greenery from it seems to be more profitable.

Growing onions in greenhouses is much more profitable starting from March. It is most convenient to plant it in small boxes with a size of 40 * 60 cm. This is done to quickly move the landings to another place, if necessary. Only in this case, you can get a good profit from it.

Growing green onions indoors from seeds

This method is less popular as it takes more time from planting to harvest.

It is advisable to use young onion seeds when planting. At least they should not be more than 2 years old.
The similarity of seeds must be at least 80%. To determine their similarity, 20 blackies are placed on a damp cloth. When sprouts appear, it will be possible to judge not only the similarity of the seeds, but also the planting density. This is necessary in order to achieve minimal losses in the sown area.

First of all, before planting, the seeds are washed for 18-20 hours in water at room temperature. Water is changed 3-4 times. Then they are treated with a 1% solution of potassium permanganate for 45 minutes and placed in a solution of "Epin" (2 drops per 100 ml of water). Keep them in solution for 18 hours at a temperature of 25-30°C. All these manipulations are necessary for the prevention of fungal diseases. After that, the seeds are ready for planting. They are planted in the prepared soil at the same depth: if the soil is heavy - by 1-1.2 cm, if the soil is light - up to 1.5 cm. When planting, this is very important, because otherwise the seedlings may turn out to be uneven.

Seeds are sown with three- and four-line ribbons. Between the rows there should be 12-15 cm, between the seeds - 1.2-1.5 cm. In order for the seeds to be evenly distributed, they must be mixed with chalk or sand - then they will be noticeable against the background of the earth.

Immediately after planting, the soil is mulched with a thin layer of peat. A film is stretched over the bed. When the first shoots appear, it must be removed to avoid burning the crops, and the seeds should be thinned out. After that, the distance between the seedlings should be 2 cm. The second time the plants are thinned out during the appearance of 2-3 leaves and the interval between them is already 3-4 cm.

Depending on what height you want to get a feather, you can carry out another thinning, making the distance between plantings 5-6 cm.

In the process of onion germination, the soil must be loosened from time to time so that oxygen enters the roots. And it is very important to weed the plants so that the weeds do not obscure the seedlings.

Experts advise feeding onions a week after planting to increase the yield. The following mixture is recommended as a fertilizer:

1 bucket of water;

15-20 g of ammonium nitrate;

30 g of superphosphate;

15-20 g of potassium chloride.

Onion greens in the greenhouse must be cut on time. The average is a leaf length of 30 cm.
