湖北省宣恩县油菜常年种植面积近5万亩,为探索油菜省工、增效途径,推动油菜生产发展,本县积极推广“双低”油菜免耕直播轻简高效一体化栽培技术。该技术是在前茬作物收获后,直接在稻茬田用机械或人工开沟、施肥、撒播种子,并将土均匀撒在畦面上覆种。这种栽种方式节省了苗床占用的耕地,省去了育苗到移栽苗等环节,免耕省去了翻地和整地的费用,直播省去了育苗到移栽的用工费用。从栽种效果来看,免耕直播油菜根系发达,苗生 Hubei Province Xuan’en rapeseed perennial planted area of ​​nearly 50000 acres, to explore rapeseed province, efficiency measures to promote the development of rapeseed production, the county actively promote “double low” rape no-tillage direct light simple and efficient integrated cultivation techniques . The technology is in the stubble crop harvest, directly in the rice stubble fields with machinery or artificial ditching, fertilizing, sowing seeds, and the soil evenly sprinkled in the noodles covered. This planting method saves the seedbed occupied land, eliminating the nursery to transplanting seedlings and other sectors, eliminating tillage and the preparation of the land clearing costs, eliminating the need for seedlings transplanting live costs. From the planting effect point of view, no-tillage live rapeseed root developed, Miao students
