Deep in the wheat field, a number of large combine harvesters along the road. The straw is crushed and spread on the ground, where it is quickly buried with stubble by rototillers. Farmers drive tricycles and tractors to transport wheat on the road near the field. Make clear the responsibility of summer grain production, do field management well in advance, give full play to the advantages of mechanical operation to rush in harvesting and planting, and concentrate on promoting the comprehensive utilization of straw. Our small loaders and tractors have played a huge role.
