秸秆还田是把不宜直接作饲料的秸秆(玉米秸秆、高粱秸秆等)直接或堆积腐熟后施入土壤中的一种方法。可改良土壤性质、加速生土熟化、提高土壤肥力。玉米秸秆还田机械化技术是以机械粉碎、破茬、深耕和耙压等机械化作业为主,将作物秸秆粉碎后直接还到土壤中去,增加土壤有机质,培肥地力,提高作物产量,减少环境污染,争抢农时季节的一项综合配套技术。 Straw is the straw should not be directly used for feed straw (corn stalks, sorghum stalks, etc.) directly or after the accumulation of maturity applied to the soil in a way. Can improve the nature of soil, accelerate the maturation of soil and improve soil fertility. Corn stalks back to mechanization technology is mechanical crushing, stubble, deep plowing and rake pressing and other mechanized operations, the crop straw crushed directly into the soil to increase the soil organic matter, fertility, increase crop yield, reduce the environment Pollution, competition for a season of farming a comprehensive supporting technology.
