保护性耕作是相对于传统翻耕的一种新型耕作技术,它是指对农田采取免耕、少耕、秸秆覆盖与保护性种植等技术,从而减少土壤风蚀和水蚀、提高土壤肥力和抗旱能力。同时,保护性耕作也可增加土壤有机质和养分含量,改善土壤结构,提高水、肥利用率,减少地表径流,降低农田扬沙,改善生态环境。近些年,保护性耕作技
Conservation tillage is a new tillage technology compared with traditional tillage. It refers to technologies such as no-tillage, less tillage, straw mulching and protective planting on farmland so as to reduce soil wind erosion and water erosion and improve soil fertility and drought resistance . At the same time, conservation tillage can also increase soil organic matter and nutrient content, improve soil structure, improve water and fertilizer utilization, reduce surface runoff, reduce farmland sand and improve the ecological environment. In recent years, conservation farming techniques
