地膜“一铺两用”技术是指上一年覆膜种植作物收获后,地块不耕翻,保持地膜原有状态,下一年在旧膜上点种另一种作物的生产模式。一、生产特点与优势1.继承传统免耕法优点,可以保持良好的土壤自然构造,促进了良好土壤结构的形成。2.由于地膜增温效应延长了膜内受热时间,加速有益 Membrane “double-use” technology refers to the previous year after harvesting the crop planting crops, the plots do not plow, to maintain the original state of the film, the next year in the old film on another crop production model. First, the production characteristics and advantages 1. Inherit the traditional no-tillage advantages, can maintain a good natural soil structure, and promote the formation of a good soil structure. 2 due to the effect of plastic film to extend the heating time within the film, accelerate the beneficial
