Onion seed planting method

Onion is a common vegetable in our country, which has high nutritional value. Onions are propagated by sowing, so how to plant onion seeds? Let's take a look at the detailed introduction.

1. Seed selection

When planting, we should first select the appropriate seeds for planting, generally choose the seeds of the current year, which can increase the germination rate of sowing. If the aged seed is selected, the life span of the seed is limited, the vigor of the aged seed is lower, and the longer the seed is stored, the lower the germination rate is, so it is difficult to germinate after planting, resulting in losses to farmers. At the same time, we should also pay attention to whether there are pests, diseases, bright colors and other problems in the color of the seeds.

2. Sowing time

Sowing time is critical, it is related to the yield and quality of onions, so sowing time must be paid attention to, although onions can be planted all the year round. But it likes the cold environment, the frost resistance is strong, the high temperature above 26 degrees will enter the dormancy condition and stop growing. Therefore, it is recommended to plant from July to September, when the temperature is about 20-25 degrees. After sowing, onions will grow at a very fast rate, which can improve the yield and quality.

3. Soaking seeds to promote seedlings

In order to improve the germination rate of seeds, it is necessary to accelerate germination before sowing, which can not only improve the germination rate of seeds, but also make the seedlings grow neatly. First of all, soak the seeds in warm water of about 50 degrees for 4 hours, make them fully absorb water, scrub the waxy layer on the surface, and then sow seeds after drying.

4. Sowing method

Onion sowing soil must be fertile and loose, good permeability soil, can also be mixed with mature farm manure to mix, can be made into the required fertile, breathable soil. Then pour the soil thoroughly, sprinkle a layer of fine soil on the soil, and sow the seeds on the soil. Cover the plastic film after sowing and control the temperature at about 20 degrees. The seeds will germinate after about a week, so it is necessary to do a good job in seedling management, timely seedling replacement, and promote seedling growth.
