保护性耕作是农业部在全国重点引进和推广的一项农机化实用技术,通过对农田实行免耕或少耕,尽可能减少土壤耕作,并用作物秸秆或残茬覆盖地表,用化学药物来控制杂草和病虫害,从而减少土壤风蚀,提高土壤肥力和抗旱能力,节本增效,保护环境,是实现农业可持续发展的一项先进耕作技术。截至2010年底,山东省兖州市保护性耕作实施面积达到1.05万hm(215.7万亩),占全市种植面积的31.6%,取得了较好的经济效益和社会效益。
Conservation tillage is an agricultural mechanization and practical technology introduced and promoted by the Ministry of Agriculture nationwide. By practicing no-tillage or less tillage on farmland, soil tillage is reduced as much as possible, and crop straw or stubble is used to cover the ground surface and controlled by chemical drugs Weeds and pests and diseases, thus reducing wind erosion, improving soil fertility and drought resistance, saving costs and increasing environmental protection, is an advanced farming technology for sustainable agricultural development. By the end of 2010, the implementation area of conservation tillage in Yanzhou, Shandong Province had reached 10,500 ha (2.157 million mu), accounting for 31.6% of the city’s planted area and achieved relatively good economic and social benefits.
