摘　　要：着重阐述了实施水田节水少耕栽培技术内容、方法、技术创新点和实施情况;分析了实施该项技术取得的经济效益和社会效益。其主要优点:一是大幅度降低水田耕整地作业时的动力消耗及费用,取消了传统水耙田、人工扬肥、耢平、沉浆和捞残茬等5项作业环节,降低了动力消耗,并由此节省了40%～50%的整地费用;二是将水田耕整地的作业周期由原来的10-15d减为1-2d;三是此项技术可节水30%～40%,是一项水稻生产的高效节水新技术;四是实现了少耕、根茬及部分秸秆还田的保护性耕作方式;五是增产10%～14%。该技术是水稻生产的一项创新技术,对水稻生产的发展具有极大的推动作用。This article focuses on the implementation of the paddy field water content of minimum tillage cultivation techniques,methods,technology innovation and implementation; of the implementation of the technology to achieve economic and social benefits. Its main advantages are：significant reduction in the paddy field tillage in power consumption during operation and costs. Cancellation of the traditional water rake fields,artificial fertilizer Yang,Lao Ping,Shen residue slurry and fishing five operating procedures,reducing power consumption and thus savings of 40% to 50% of the site preparation costs; the paddy field to the operating cycle Tillage from 10 to 15 days was reduced to 1 to 2 days; this technology can be 30% ～ 40% water,is a highly efficient water-saving rice production technologies; achieve some minimum tillage and stubble and straw of conservation tillage methods; yield 10 % ～ 14%. This technology is an innovative technology of rice production,rice production has a great role in promoting development.
