How many crops can southern wheat grow a year?

Wheat in the south can be planted once a year.

1. Rice in the south can be cooked twice or even three times a year, and wheat, corn and soybeans are cooked once a year. Wheat needs low temperature at tillering stage, so there is winter wheat south of the Great Wall. Spring wheat can be planted in the northeast, and harvested from south to north before and after awning. It's the summer harvest near Beijing.

Soybean can be sown from spring to summer. As the saying goes, Grain Rain planted melons and beans before and after. Before new varieties appeared, spring beans were sown in Grain Rain, not in early autumn. There is a great difference in the length of the growth period. The famous "Yanming" didn't mature until first frost, but the maturity of traditional beans was much shorter.
