Greenhouse requirements

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 borne in mind that it will need to be replaced every year, so is it that cheap? On the other hand, saving on covering in the first year will make it possible to purchase the necessary tools and equip the premises. One of the inconveniences in this coating is the annual assembly / disassembly.

In the long term, growing green onions in a greenhouse will be the best material for polycarbonate. The main advantages of this material:

• reduction of heat loss, which means a decrease in heating costs;
• decent strength;

• on the shelves, the soil warms up faster, as a result - the growth period is reduced by 12-15 days on average;
• the construction of shelving relieves a person from the need to bend his back and crawl on his knees;
• watering plants will require less water, and this is already saving;
• when constructing multi-tiered racks, the landing area is automatically increased.

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

By and large, the greenhouse is now ready.

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

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

Each type of onion has its own planting technology.

So, the onion can be grown by seedlings and seeds, starting in December. Sowing is carried out densely: 3g is used per 1 sq.m. plot. Using 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 distillation, when harvesting, the green leaves are pulled out together with the underdeveloped bulb, otherwise, only greens are cut off. It should be noted that three-year-old bulbs are fertile.

Slime onions are grown in three ways: by dividing the bulbs, by seeds or seedlings. After planting any type of onion, it must be watered with warm water.

Onions are grown in the greenhouse from the end of November. In this case, the crop can be harvested after 30 days.
