[0002] Straw is the general term for the stems and leaves (ears) of mature crops. It saves labor and improves soil fertility. It is the most convenient and most profitable way of processing. Straw usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after harvesting seeds. More than half of the products of crop photosynthesis are present in the straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource. Straw is also a roughage, characterized by a high crude fiber content (30%-40%) and lignin.

[0003] After the straw is crushed, it is put into the farmland to improve soil fertility. After the straw is crushed, the dust on the surface will fall with the crushed straw.
