残留地膜对农业环境影响的研究初报

A Tentative Report on the Study of the Impact on Agriculture Environment due to the Remalinder Plastic Sheet Covered the Soils.

本研究从调查入手,进行了不同覆盖年限,耕作清膜方式、清膜时间、覆膜方式等条件下地膜残留数量和分布情况的调查。同时,采用人工模拟的方法,进行了不同地膜残留数量对作物产量、作物生长状况和土壤物理性状影响的试验,结果表明,地膜残留对它们都有显著影响。

A survey was conducted on the quantity and distribution of plastic sheeting residues under different conditions. The mulching years. the different ways of mulching and removal of the plastic shcets. The influence of plastic sheeting residues on the production of crops, the growth of crops and the soil physical characteristics were also tesed by the mathod of artifical simulation. The results show that the plastic sheeting residues affected the production and growth of crops and soil physical characteristics obviously.
