Onions occupy the first place among green forcing plants, being the most valuable product in the winter. It is used both fresh and fried, stewed and boiled. There are several different options for growing onions on a feather in a greenhouse.
- Preparatory work
- Planting technology and recommended species
- We grow onion greens correctly
For the year-round cultivation of vitamin greens, first of all, it is necessary to choose the right varieties and hybrids. Strict adherence to agricultural technology and soil fertility is of no small importance. Planting onions in greenhouses begins in October in wooden or plastic boxes, which can be stacked on top of each other. After a two-week period, they are taken out and installed in greenhouses, where further forcing is carried out. The agro-technical economy in onion cultivation is based on the correct and timely preparation of the material for planting.
In terms of economy, it is more expedient to use southern varieties of onion selection, the size of which does not exceed the average. They have a short dormant period, which allows for fast yields.
To further shorten the dormant period and significantly increase the yield, the planting material should be soaked in warm water for at least 12 hours. Having taken out the bulbs, they are dried, after which the necks are carefully cut off. This will speed up the appearance of greenery. Another variant of acceleration is possible, in which the onion to be planted is poured in a warm room in heaps, watering with water, the temperature of which should not be higher than 30 degrees.
After that, the bulbs are covered with burlap, keeping under it for at least 4 days.
The speed of forcing a feather largely depends on the planting time and on average ranges from 13 to 22 days. The varieties and quality of the material are also of great importance. Experience shows that if the optimal technologies for growing onions on a feather in a greenhouse are observed, greens appear already on the 4th day, giving a subsequent increase of up to 3 cm per day. Good prospects for forcing are shallots, popularly known as "kuschevka". True, due to the length of the dormant period, it is recommended to plant it no earlier than the second half of winter.
Planting technology and recommended species
It is necessary to plant onions in the ground in a bridge way, tightly pressing the bulbs together. This allows you to significantly save space by driving out beautiful, juicy greens. With this method, you will need about 10-12 kg of planting material per square meter. The air temperature should be within 22 degrees. Watering plantings no more than once every 10 days. From the age of two weeks in the greenhouse there should be constant lighting that will not allow the greenery to turn yellow and become not juicy.
When choosing varieties for planting, pay attention to the most recommended for greenhouse cultivation, species that have a minimum dormant period. These include:
- Tiered bow
- Slime onion
A short description of each type will help you make the right choice.
- The multi-tiered bow is considered the most profitable and unpretentious. It can be grown in low light and relatively low temperatures. In this case, the seed material is underground bulbs (false) and bulbs, 1 kg of which is capable of giving at least 2 kg of high-quality high-quality greens within 25-30 days.
- Slime onion is a very early maturing and frost-hardy species that has become widespread in recent years. With wide leaves with rounded ends, the most delicate taste and light garlic aroma, it looks little like an onion. This high-yielding species can grow all year round, so it can be planted in a greenhouse at any time. For this, bulbs with rhizome pieces are used. The plant is very unpretentious and does not need high temperatures.
- Onion-batun, in comparison with onions, has more leveled greens and a fairly low cost. Therefore, distilling greens from it seems to be more profitable.
- It is much more profitable to grow onions in greenhouses starting in 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 plantings to another place, if the need arises. Only in this case you can get a good profit from it.
Using the correct technology for growing onions on a feather in a greenhouse, you can grow an excellent harvest from each of the listed species.
We grow onion greens correctly
Preparing the soil for forcing is essential. It should be enriched with easily digestible nutrients. To do this, the soil must be mixed with peat and humus, add superphosphate 30 g / weave and sodium chloride 15 g / weave, and also moisten well.
Leek on a feather
Leek, which has an extraordinary taste and delicate aroma, is grown with the help of seeds, which are soaked before being planted for 5-6 hours in lukewarm water. It is advisable to disinfect the water by adding "Epin" or "Zircon" to it, which along the way will stimulate plant growth. To obtain seedlings, the seeds must be planted in separate containers. The amount of soil in them should not exceed 2/3 of the volume.
The seeds are sprinkled with earth, after which the containers are covered with glass or film and transferred to a warmer place. Watering is carried out no more than once every 3 days, and the film is not removed until the greenery appears completely.
Before replanting the onions in the greenhouse, the soil is fertilized with humus and ash. When planting, the distance between the bulbs should be at least 10 cm. To obtain juicy, non-bitter greens, water the leeks at least once a week and periodically weed the weeds.
Getting a tall white leg is achieved with some tricks. Before planting the bulb, a deep groove is cut in the ground, to the bottom of which the planting material is immersed. As it grows, the earth is constantly poured, due to which the leek "climbs" up.
The technology of growing onions on a feather in a greenhouse is not difficult. Reproduction of the plant occurs with the help of a large number of thickening of the rhizome, growing during the entire growing season. In the last days of autumn, chives are dug out of the ground and left to "rest" for 21 days, after which they begin to plant them in greenhouses.
To awaken the plant from sleep, it must be planted in loose soil, watered with warm water. Until the germination of greens, it is necessary to maintain the temperature within 22 degrees, when a feather appears, it is reduced to 16 degrees.
Chives need sufficient lighting to form tasty and beautiful feathers. With a lack of it, the plant will be pale and weak. Onions need regular, not very abundant watering, high humidity can cause rotting. The main forcing of feathers lasts from 3 to 6 weeks. The finished crop is cut, leaving the bulbs intact. From them you can get another good portion of greens.
For growing greens, mainly onion sets or onion heads are used, the diameter of which should be at least 2 cm. The number of harvests depends on the size of the head, the larger it is, the better. Large bulbs have a high supply of feathers. Immediately after planting, the onions are watered with lukewarm water. For the full development of the root system, it is necessary to maintain the temperature within 12 degrees for several days. After that, the temperature is raised to 20 degrees, keeping in this mode until the harvest is completely distilled.
Observing the technology of growing onions on a feather in a greenhouse, the harvest can be obtained as early as 25 days. And besides this, from November to March, you can get about 4 fees, building a good business on this. For regular harvests, onions can be planted every 10-15 days, creating a non-stop conveyor.
Using the greenhouse allows you to get tasty and healthy products despite the weather outside the window. Maintaining optimal air and soil temperatures, timely watering and feeding will respond with an excellent reward.
