一、盖平不盖坡:覆盖的土地要选择平地、下湿沟湾地,不要选在坡梁上,坡梁地覆盖经济效益不高。二、盖肥不盖瘦:覆盖的必须是肥沃的土壤,或者是有机化肥施用量充足的土壤,否则会产生严重的后衰现象。三、盖湿不盖干:为了使覆盖以后的种子有足够的发芽水分,必须保证覆盖保墒,盖湿不盖干,应在土壤夜冻昼消时就覆盖,或者是雨后抢盖。四、盖早不盖晚:覆盖要在作物播种前10—15天进行,覆盖的土地最好要在头年秋季做好整地、施肥。不要翻地、施肥、覆盖、播种一齐进
First, the cover does not cover slope: cover the land to choose flat, wet ditch Bay, do not choose on the slope, slope to cover the economic benefits are not high. Second, the cover does not cover lean: Cover must be fertile soil, or organic fertilizers sufficient amount of soil, otherwise it will have a serious after-effects. Third, the wet cover does not cover dry: In order to cover the seed after germination has enough water, must ensure that the coverage of soil moisture, cover wet does not cover dry, should be covered in the soil when the day is cold, or grab the cover after the rain. Fourth, the lid will not cover the night: covering the crop 10-15 days before sowing, covering the best land in the first year to do a good job of land preparation and fertilization. Do not turn over, fertilize, cover, sow seeds together
