I saw several people grinding wheat with wheels in the TV series "The Old Farmer". What is this? Didn't you run over all the wheat? Excuse me, what is that job?

When planting winter wheat in North China, stepping on wheat seedlings mainly occurs before winter, because wheat grows vigorously before winter, and it is easy to lodging in the later period, which consumes too much nutrients and affects wheat yield. Crushed wheat seedlings are damaged objectively, and the aboveground parts can reduce nutrient consumption, promote the vigorous growth of wheat seedlings, and increase the cold resistance and drought tolerance during overwintering. In addition to stepping on wheat seedlings, you can also use the control method of deep ploughing and root cutting. The main time is around beginning of winter and before winter.

Hope to adopt
