Can winter wheat be sown in spring (when to sow winter wheat and spring wheat)

China has a vast territory and many places for growing wheat. According to the sowing season , wheat is divided into winter wheat and spring wheat. Winter wheat is sown in September-October in autumn and harvested in May-June of the following year, experiencing the low temperature in winter, while spring wheat is sown in March-April in spring and harvested in July .

It is difficult for winter wheat to produce ears if it is sown in spring . Why?

Because winter wheat has to undergo low-temperature training in winter, that is, it has to go through the vernalization process before it can differentiate flower buds. Otherwise, it will not bloom or will bloom delayed, and it will only grow stalks and produce few or even no ears, resulting in serious yield reduction.

Winter wheat is mostly distributed in areas south of the Great Wall, such as Henan, Shandong, Shaanxi, Shanxi and other places.

Spring wheat is suitable for sowing in areas with cold winters. Because the winter is too cold, frost damage is likely to occur, affecting the growth of wheat. Therefore, early sowing in spring and growing it under warm and cool conditions is one of the key measures to increase spring wheat production.

Spring wheat and winter wheat have different varieties. When selecting high-quality spring wheat varieties, one must first consider the ecological conditions of the region and the requirements for the varieties. Second, one must select large, plump, uniform, and pure seeds. Third, one must pay attention to seed mixing with pesticides or coating treatments to prevent diseases and pests and cultivate strong seedlings .

After determining the good varieties of spring wheat, within the appropriate sowing period, on the basis of ensuring sowing quality, the earlier the sowing, the higher the yield. Early sowing means high yield, and late sowing means reduced yield.

When is the best time to plant spring wheat?

Generally speaking, it is more suitable when the local temperature is between 0 and 2 degrees on average day and night and the soil surface thaws by 5 to 7 centimeters, which is just above the sowing depth. The sowing depth is generally 3 to 4 centimeters.

Spring wheat has a short growth period, few tillers, and a low ear formation rate. Its yield mainly comes from the main stem ears, so the sowing amount should be appropriately increased to increase seedlings and ears to increase yield. However, under good fertilizer and water conditions, the tillering of spring wheat also plays an important role and cannot be ignored.

In order to increase the yield of spring wheat, we should cultivate the land carefully, improve the sowing quality, and increase the number of ears per mu by increasing the field emergence rate and tillering rate.

If you want to sow winter wheat in spring, the winter wheat variety you choose must be treated with low temperatures. That is to say, the newly sprouted winter wheat seeds must be treated at a low temperature of 0-5 degrees for 40-50 days before they can be sown, which can solve the problem of only growing seedlings but not earing .
