When is the best time to raise onions?

Onions are suitable for seedling cultivation in September every autumn.

Onion, also known as onion, is a very popular vegetable, which is widely cultivated in China. Onion is popular among farmers because of its easy cultivation, easy management, high yield and good economic benefits. Every autumn is the season of onion sowing. Onions planted are mainly harvested bulbs, and onions are seasonal.

Seedling raising will directly affect the yield and quality of onion. Generally, the best time to raise onion seedlings is after the Millennium solar term, and the best time is in mid-September. At this time, the temperature has dropped significantly, and the temperature difference between day and night is also widening. There is a tradition that onion seedlings are raised as early as August and as late as 10, and the seedlings are raised in September.

Harm of premature seedling raising

It is harmful to raise onion seedlings too early, because the seedlings grow fast at high temperature. Before winter, plants grow too fast and consume a lot of nutrients. Once the temperature fluctuates, onion seedlings are prone to vernalization. The next spring, when the onion begins to grow, it will bolt early. Once the onion bolting occurs.

This means that the quality and yield of onion bulbs have been seriously reduced, and the competitiveness of smoked onions in the market will be greatly reduced. It is also harmful to raise onion seedlings too late. Before winter, the vegetative body of onion seedlings is too small, the cold tolerance is reduced, and the seedlings can't stand the cold and freeze to death. In the second spring, it is easy to appear the phenomenon of lack of seedlings and broken ridges.
