近年来,许多地方都大面积使用地膜,增产效果显著。但是若干的废地膜却残留在田间土壤中。地膜是碳氢高分子化合物,在土壤中难以分解,沤不烂,长期下去将会破坏土壤结构,妨碍作物生长。所以,应高度重视,妥善解决,做到防患于未然。为了科学管理回收废旧地膜采取如下一些措施很有必要。一、各技术部门,各生产,应用单位,不仅要做好地膜覆盖应用
In recent years, many places are large-scale use of plastic film, yield significant results. However, some waste film remains in the soil in the field. Film is a hydrocarbon polymer, difficult to decompose in the soil, not bad, long-term will destroy the soil structure, hinder crop growth. Therefore, we should attach great importance to proper solution so that we can take preventive measures in the first place. In order to scientifically manage the recovery of waste film to take the following measures are necessary. First, the technical departments, production, application units, not only to do a good job of mulching application
