小麦全膜免耕穴播栽培技术为覆一次膜,种植多茬的免耕栽培技术,既节约劳动力、节省成本,又可保护地表,减少表土流失和风蚀,改善生态环境,经济、社会、生态效益显著,在旱作农业区十分具有推广价值。选择土层深厚、土壤肥沃的川塬、梯田、沟坝、缓坡(15°以下)地种植,一般在10月中下旬播种。选用厚度为0.008～0.01mm,宽70cm或120cm的高强度地膜,铺膜依据土壤墒情而定。播种后加强肥料、病虫害防治等田间管理,并及时收获,为下茬作准备。
Whole wheat film no-till seedling cultivation technology to cover a film, planting more stubble tillage cultivation techniques, both labor-saving and cost savings, but also protect the surface, reduce surface erosion and wind erosion, improve the ecological environment, economic, social and ecological benefits Significantly, in dry farming areas is very promotional value. Select the deep soil, fertile Sichuan plateau, terraced fields, ditches, gentle slope (15 ° below) to grow, usually in late October planting. Use the thickness of 0.008 ~ 0.01mm, width 70cm or 120cm of high-strength film, film-based soil moisture may be. After sowing to strengthen fertilizers, pest control and field management, and timely harvest for the next crop in preparation.
