In addition, there are different requirements for green onions at different sowing times:

Spring-planted and autumn-harvested green onions require fast growth, heat resistance and Rain Water, and high yield. Puwei Star No. 3, No. 4, Minghui and the new champion are available. Generally speaking, small leaf varieties are not selected for this crop.

Spring-sown and winter-harvested Welsh onions require good merchandise, high commodity rate, strong low temperature tolerance and high yield, so Yudu Welsh onions, Star No.2, Mingmen, Changfeng Welsh Onions and Fengyu are the most ideal varieties for this stubble.

Spring onion varieties planted in summer and autumn are resistant to bolting, disease resistance, high yield and delayed harvest, so Puwei long summer, spring late harvest and famous late harvest are the best varieties.

Spring onions harvested in winter are required to be resistant to low temperature, bolting, strong disease resistance and delayed harvest, so Puwei long summer, late spring harvest and late harvest are used for raising seedlings in September, and Star No.2, Mingmen and Fengyu are used for raising seedlings in October.

2. Sowing method of green onion

The seeds of Welsh onion are small, the seed coat is thick, the cotyledons are unearthed, the seedlings grow slowly and the seedling stage is long. In order to shorten the occupation time and facilitate the management, seedling raising and transplanting were carried out. The seedbed should not be replanted. After the previous crop was harvested, it was fertilized deeply and was generally made into a high border with a width (continuous ditch) of 1.4 meters. The seedbed should be finely arranged, and the bed should be permeated with water before sowing and sowed with new seeds. The amount of seed used in the field is 75m / mu and 100g. After sowing, cover 2 cm of soil, and then cover rice straw or film to increase temperature and moisturize and speed up seedling emergence.

After sowing, it is also necessary to carry out field management, reasonable watering, fertilization and pest control of green onions.
