免耕免耕no-tillage播种前不单独进行土壤耕作直接在茬地上播种，作物生长期不进行土壤管理的耕作方法。用联合作业免耕播种机一次完成切茬、开沟、喷药除草、播种、覆土多道工序。广义免耕包括少耕。传统的免(少)耕技术在中国耕作史上出现较早。20世纪40年代，美国进行了少耕研究，发现残茬覆盖有保护土壤的作用。除草剂和免耕机的研制成功，为免耕播种提供了可能，并因能源紧张，使免耕技术得以发展。美国60年代开始应用于玉米、高粱、大豆和烟草等作物生产。以后逐渐为各国所重视和采用。免耕的优点：①减少耕作机械多次作业而压实、破坏土壤结构。②降低成本和能耗。③地面保存残茬覆盖，有利蓄水保水、防止水土流失和土壤风蚀，减轻环境污染，提高土地利用率。但早春土温较低；残茬分解产生有毒物质；病、虫、杂草防除效果欠佳，均影响下茬作物生长，有待解决。免耕不适于低洼易涝土地、土壤质地粘重和耕层结构不良的土地。
