秸秆还田是农业可持续发展的重要措施,具有很好的经济效益、生态效益和社会效益。山东省小麦栽培面积有366万hm2左右,玉米栽培面积有300万hm2左右,机械化收获使小麦、玉米秸秆粉碎或半粉碎留在农田里。两茬作物留存秸秆数量每亩地达到4 000 kg左右。怎样科学合理有效地处理这些秸秆,是农民最头疼的问题。 Straw is an important measure for the sustainable development of agriculture and has good economic, ecological and social benefits. Shandong Province has a cultivated area of ​​3.66 million hm2 and a maize cultivation area of ​​3 million hm2. Mechanized harvest leaves wheat and corn stalks in the field after they are ground or semi-ground. The amount of stalks remaining in two crops reached about 4,000 kg per mu. How to deal with these straw scientifically and effectively is the most troublesome problem for peasants.
