小麦全生育期覆膜穴播是一项能大幅度增产的新技术。它采取先覆膜后播种的方法，即先用０．００５毫米的超薄膜覆盖地表，后用机械或人畜力播种机进行自动打穴播种的一种技术。它改条播为穴后播，把小麦短期覆膜改为全生育期覆膜，尤其是在旱地和高寒山区，覆膜穴播效果好。小 The whole growing period of wheat film-mulching is a new technology that can greatly increase production. It takes the first method of seeding after sowing, that is, first with 0.005 mm ultra-thin film covering the surface, after the use of mechanical or human-powered sowing machine to sew a hole in a technology. It changed the sowing for the hole after sowing, the wheat short-term film to cover the whole growth period, especially in the dry land and alpine mountains, film-sowing effect is good. small
