地膜覆盖栽培,为农作物生长发育创造了良好的土壤温度、水分、养分等条件。一般地块地膜覆盖率都在65％以上,而作物所用覆盖面积,是随作物生长发育时间逐渐增大的,而且覆盖畦间的沟距一般都在1尺以上,因此,合理调节作物行距、充分利用播种或定植后前期剩余的大部分覆益面积,进行套种 Film mulching cultivation, crop growth and development has created a good soil temperature, moisture, nutrients and other conditions. In general, the mulching area of ​​the plots is above 65%, while the area covered by the crops is gradually increased with the growth and development of the crops, and the furrow distance between the mulches is generally over 1 foot. Therefore, the crop row spacing, Make full use of the sowing or planting the majority of the rest of the area after the initial coverage, intercropping
