一、覆盖形式小麦是条播、小行距、高密度、大群体作物.应用地膜覆盖时,就不能套用瓜菜、棉花等作物的打孔播种或开孔放苗的覆盖形式,而应采用盖苗的方式.一膜盖几行麦苗,不打孔,不划口,让麦苗在膜下生长.利用地膜的增温保墒作用,使麦苗生长加快,提早发育,增加群体,达到增产的目的,而且还能保持地膜完整,供二次利用.
First, the coverage of wheat is sowing, small row spacing, high-density, large groups of crops.Application of mulching, you can not apply vegetables, cotton and other crops perforation sowing or opening seedling coverage form, and should be used to cover seedlings A film cover a few rows of wheat seedlings, no punching, not cut mouth, let wheat seedlings grow under the film. The use of plastic film warming moisture effect, so that wheat seedling growth accelerated, early development, increase the population, to increase production purposes, and Can also keep the film intact for secondary use.
