[0002] Straw is a general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after the seeds are harvested. More than half of the products of crop photosynthesis are present in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. In the past, straw was not very useful to farmers, so in order to save time and reduce pests and diseases, it was usually burned. However, with the development of society, people are paying more and more attention to air quality and environmental pollution, and burning straw is prohibited.

[0003] At present, the straw is processed as follows: the straw is crushed, decomposed with drugs, and then deep plowed and buried by mechanized farming. The next season's crops are planted in the new soil layer or composted and fermented before being returned to the field as fertilizer, forming a green circular agriculture.
