When is it suitable to grow wheat in Northeast China?

1. Wheat is sown in late March and early April, and harvested in the middle and late July. Spring wheat has strong drought resistance, short ear and short growth period, which is suitable for spring sowing, but it is not as delicious as winter wheat flour.

2. After the seeds of wheat germinate in the soil, they must go through a certain period of low temperature conditions before they can get up and jointing and form a solid plant. This period is called vernalization stage of wheat. The temperature required for winter varieties to pass the vernalization stage is relatively low, generally at 0℃ ~ 3℃ for 40 ~ 45 days.
