玉米机械化保护性耕作是利用还田机械或收获机械将秸秆直接粉碎后均匀抛洒在地表,然后实施机械免(少)耕播种,已达到改善土壤结构、培肥地力、提高抗旱能力、减少风蚀、水蚀、节本增效实现农业可持续发展的一项先进耕作技术。土地是农业生产的根本,传统的耕翻作业不仅增加生产成本,而且破坏土壤结构,增加土壤风蚀和水蚀,降低土壤的生产能力;秸秆焚烧,乱堆乱放和大量施用化肥,
Maize mechanized conservation tillage is the use of straw or straw harvesting machinery directly crushed straw evenly sprinkled on the surface, and then implement mechanical (less) plowing, has been to improve the soil structure, fertility, drought resistance and reduce wind erosion, Water erosion, the section of the efficiency of agriculture to achieve sustainable development of an advanced farming techniques. Land is the foundation of agricultural production. The traditional tillage operation not only increases the production cost, but also destroys the soil structure, increases the soil erosion and water erosion, and reduces the productivity of the soil. Straw burning, messing up and mass application of fertilizers,
