摘　　要：水土保持保护性耕作是对农田实行免耕少耕,并用农作物秸秆残茬覆盖地表的一项先进耕作技术,保护性耕作技术是由秸秆覆盖、免耕播种、机械深松和化学除草等核心技术组成的一项集成技术,采用水土保持保护性耕作措施可以有效减少东北黑土区的水土流失,提高黑土区土壤抗蚀性。对保护黑土地、改善生态环境、生态省建设都具有重要意义。Soil and water conservation protective cultivation is an advanced cultivation technology that avoid cultivation or few cultivation on farmland and with stubble cover. Protective cultivation technology is an integration technology that use stubble cover, no-tillage cultivation, deep-plough with machine, and weeding with chemistry. Adopting soil and water conservation protective cultivation can reduce the loss of soil and water in northeast blackland area and improve the soil anti-erodibility. It has great significance for protecting blackland, improving ecological environment, and establishing ecological province.
