Planting onions on a feather (on greens) in a greenhouse in spring: the best varieties, growing features, yield

Any fresh greenery is especially popular in the winter and spring, when the gardens are still swept up by snow, and not everyone has heated greenhouses. True, if we talk about forcing onions on a feather, then onion varieties are the least suitable for winter time, since they require more heat and light than their perennial varieties. Planting onions in the spring on greenery in a greenhouse is more justified, since it often allows you to do without additional heating and lighting and, as a result, get much better yield results.

Features of growing onions on a feather in a greenhouse

For normal and fruitful forcing of onions, two basic conditions are vital: temperature and light. Of course, the humidity and quality of the soil also play a role, as well as the quality indicators of the seed material, but the latter will be discussed in detail in the next chapter.

Forcing onions on a feather can occur at temperatures from + 8 ° C to + 25 ° C. At the time of planting, it is desirable that the temperature be within + 18-22 ° C. Of course, in the middle lane in a greenhouse, such a temperature can form only in the daytime. At night, you will most likely need to use additional heating. To keep warm at night, it is important to pay attention to good thermal insulation of the greenhouse. This issue should be taken into account even at the stage of its construction, so as not to save too much on the thickness of the greenhouse coating material.

To simplify your task, it is advisable to use racks or special tables raised above the ground for planting onions on a feather. After all, the air in greenhouses warms up much faster than the soil below, and this will reduce heat costs for heating. In addition, racks can also provide an increase in landing area if they are made in two or even three tiers.

In the first 8-12 days after planting, onions practically do not need light, and then 12 hours of daylight is enough for good development. A similar level of illumination may well be provided without the installation of additional lamps, if the onion is planted no earlier than the beginning of March.

For successful forcing of onions on a feather, the air in the greenhouse should not stagnate, and there should not be too high humidity inside. Together, these factors have a depressing effect on the growth of greenery and can lead to various unpredictable diseases. To reduce humidity, you can adjust the temperature (reduce it). For air circulation, you can use a regular household fan, and in warm weather, be sure to ventilate the greenhouse.

Watering onions grown on a feather is vital only at the very beginning of the process, after planting. Then a lot depends on the temperature and conditions that will be in the greenhouse.

The best onion varieties for greens for growing in a greenhouse

If the cultivation of onions for feathers is made one of the means of income, then the choice of the most suitable variety is the basis of the foundations of possible profitability. You should choose from those varieties that will be either multi-nested or multi-germ. There are several varieties that are most beneficial to use for forcing on a feather in greenhouses.

Karatal

One of the best varieties for growing in feather greenhouses, as it is both multi-primitive and multi-nested. In addition, he has a very short rest period, and he is able to wake up early. Having planted it, you can always be sure not only of the quality of the crop, but also in the early terms of its receipt.

Rostov local (Lugansk)

Good results when grown on a feather are also shown by the local Rostov onion. It has at least three rudiments, and it is characterized by an average dormant period. This variety has another remarkable property – the fleshy feather that inspires respect. When planting large bulbs with a diameter of more than 5 cm, the crop can be harvested more than decent – up to 15-18 kg per 1 sq. m.

Stuttgart Riesen

Although this onion has a long dormant period, it is ideal for forcing greens in a greenhouse in the spring. More than three rudiments can always be found in it, and it forms a powerful, beautiful and healthy feather. Plus, it’s pretty easy to get. The variety is known and found almost everywhere.

Egyptian

This is a rather conditional name for onions for growing on a feather. Since it is of imported origin, it may not be too easy to get it. But it has many buds and grows well.

Chalcedony

Although this onion usually has no more than 2-3 primordia, it is characterized by unpretentiousness and good growth, and most importantly, it is found everywhere. It will not be difficult to find its seeds for planting. Approximately the same properties are distinguished by the varieties Bessonovsky Urozhny, Danilovsky 301 and Strigunovsky Local.

When can you plant onions in a greenhouse?

In the conditions of the middle lane (the latitude of the Moscow region), it hardly makes sense to plant onions for forcing on a feather in a greenhouse before the beginning of March. Planting earlier will result in lower yields, or higher green feather costs.

In more southern areas, of course, it is allowed to plant onions on a feather even earlier, during February.

Soil preparation and planting material

Onions on a feather can be planted both on a soil substrate, the basis of which is ordinary garden soil, and on artificially created soil, the basis for which are sawdust. It is advisable for beginners in this business to use ordinary soil, which is located in the greenhouse. It is only necessary to mix it with humus or compost in the fall, adding a bucket of these components per 1 sq. m. soil.

You can grow onions on a feather even in boxes placed on the surfaces of racks. In this case, the thickness of the earth layer in them is approximately 5-6 cm. If the boxes are sealed or covered with plastic wrap, then drainage holes should be provided in them to drain excess liquid during irrigation. Otherwise, the bulbs can simply rot from excessive moisture.

The preparation of the onion itself consists of several procedures. To begin with, before planting, the onion must be brought into a warm room for several days and let it warm up. After all, onions are usually stored at a temperature of about + 5 ° C so that it does not germinate.

Then the bulbs must be sorted by size. Bulbs with a diameter of 3 to 8 cm can be used for forcing. Larger bulbs may no longer give the expected effect of adding a crop, and smaller ones will form too thin and weak feathers.

It is best to have bulbs of approximately the same size in the box. In this case, germination will be more uniform. To speed up the process, as well as for a more beautiful and uniform germination of the feather, the necks of each bulb are cut off, leaving about ¾ of the bulb itself.

Equally important is the soaking procedure. In extreme cases, you can do without it, but it significantly speeds up the germination process and, most importantly, disinfects the planting material. Onions are usually soaked directly in bags in warm water at a temperature of + 50 ° C with the addition of potassium permanganate.

Planting onions on greenery in a greenhouse

Planting onions on a feather in greenhouses can theoretically be done both with the help of ready-made bulbs and with seeds – the so-called nigella.

Seeds

This method is incredibly laborious and time consuming. Therefore, it is suitable only for those who do not have the means to buy ready-made bulbs for planting in the right quantity, but have a lot of free time and a desire to mess with onion seedlings.

In this case, usually in the spring, black onion seeds of a suitable variety are sown in boxes and seedlings are looked after for a whole year until next spring. In summer, they are seated more freely, so that by late autumn they can turn into more or less decent-sized bulbs. Then they are dug up and stored in a cold place until spring, to be planted in the usual way, which will be described below.

Bulbs

When growing feathers from bulbs in greenhouses, the bridge planting method is most often used. In this case, 1 sq. m. usually spend about 25-30 kg of finished bulbs. This amount is about one standard mesh bag of onions.

How to plant onion sets on greens in a greenhouse

With the bridge method, pre-prepared bulbs are planted almost on the surface of the earth with a cut up, deepening them by only 1 cm. Moreover, the planting density should be such that almost all bulbs are in contact with each other with all their parts. From the bulbs, figuratively speaking, they line the bridge, hence the name of this planting method. Thus, a large amount of space is saved, which is especially important for small areas in compact greenhouses.

When you first land on it, it can take quite a long time. With gaining experience in landing 1 square. m. in this way should take no more than 30 minutes for one person.

How to grow onions for greens in a greenhouse

In the process of caring for a growing green feather, no particular difficulties are observed. Bulb rooting usually occurs within the first 10 days. Then the first green sprouts appear. During this period, by changing the temperature, it is possible to regulate the intensity of onion growth. For example, if before the holidays it is necessary to “keep growing” a little, then the temperature is lowered, but so that it does not drop below + 8 ° С. Conversely, as the temperature rises, the growth rate of the feather accelerates significantly. But even here there is a limit. When the temperature rises above + 25 ° C, the tips of the leaves may begin to dry on the onion, which adversely affects the presentation of the vegetable.

Watering

Watering is necessary only when growing onion greens in fairly warm conditions, when the earth has obvious signs of drying out. It can be carried out both from a hose and from a watering can. The temperature of the water does not matter much, but it is still better to use settled rather than ice water.

Weeding and loosening

There is no need for weeding and loosening, since the bulbs occupy absolutely the entire area of ​​uXNUMXbuXNUMXbthe soil. But a periodic sample of diseased or starting to rot bulbs is simply necessary.

Additional fertilizing

Usually, if a feather onion has been planted in the ground fertilized with humus since autumn, then it does not need any additional feeding. But periodic spraying with Fitosporin will allow for the prevention of possible diseases and save most of the healthy bulbs from possible infection.

Harvesting

In general, a sign of the readiness of onion greens for harvesting is the length of the leaves. It should reach at least 25-30 cm. But it is better to wait for the length of onion feathers from 40 to 50 cm. This will allow you to get the maximum green yield by weight.

Usually in the spring, the period from planting to harvest averages about 30 days. It can vary from 20 to 40 days.

The very process of harvesting consists in the fact that with a sharp knife the onion is cut at the root along the very surface of the substrate. Then a cut is made at the bulb at the very bottom. The bulb is pulled together, and a clean and dense green of the feather remains in the hands. Its white part is cleaned of a slippery film and put in a prepared box. Each bulb is treated in the same way. The old bulb is thrown into the compost heap.

It should be noted that the average yield is from 25 to 65% of the weight of the original bulbs. That is, if 100 kg of onions were planted, then you can get from 25 to 65 kg of green onions. Productivity is most of all determined by the number of buds in the variety used. Thus, from one square meter in a greenhouse, you can get from 8 to 20 kg of early green onions.

Pests and diseases

Invasion of pests or diseases is much easier to prevent than to treat. And this statement is more than true in relation to the cultivation of onions on a feather. Since it lasts only about a month, no treatment here makes sense. It is only necessary:

• very carefully sort out the bulbs before planting;
• carry out the disinfection procedure before planting;
• use Fitosporin regularly;
• periodically inspect the plantings and remove any bulbs that begin to deteriorate;
• regularly ventilate the greenhouse and use a fan to circulate the air.

Conclusion

Planting onions in the spring on the greens in the greenhouse can be an effective help in fortifying the family. And also it can serve as a good auxiliary income. And if everything works out and the goods are in demand, then it is possible, if desired, to expand the sown area and take this matter seriously.
