机械化保护性耕作技术是用机械通过深松、秸杆根茬还田、免耕播种等机械作业对农田实行免耕、少耕,用大量作物秸秆和根茬覆盖地表,用化学药物来控制杂草和病虫害,以减少土壤风蚀、水蚀,有利于保水保土和提高土壤肥力,实现旱作农业可持续发展的一项先进农业耕作技术。保护性耕作与传统耕作方法的区别是:秋收后不翻地,春播前不犁田,省
Mechanized conservation tillage technology uses no mechanical tillage and no tillage on farmland through machinery such as subsoiling, straw stubble and no-tillage sowing, covering the surface with a large amount of crop stalks and stubble, and controlling chemical compounds Grass and pests and diseases to reduce soil wind erosion, water erosion, soil and water conservation is conducive to improving soil fertility and achieve sustainable development of dry farming an advanced farming techniques. The difference between conservation tillage and traditional tillage methods is that the crop will not be plowed up after the autumn harvest and will not be plowed before spring
