光和生物双降解地膜在生产中应用试验研究

Application of Photo-& Bio-degradable Mulching Film in Agricultural Production

地膜的应用促进了生产的发展 ,但是由于大量地膜残留 ,造成农业环境污染 ,影响了农业可持续发展。光和生物双降解地膜在光和生物的作用下自行降解 ,从根本上解决了农用地膜残留问题。光和生物双降解地膜在作物生长期内 ,可有效提高土壤温度和土壤水分含量 ,促进作物生长发育 。

The application of the mulching film has made an advance in agricultural production. But as the widely use of the mulching film, there are a lot of residuum of mulching film left in the soil which Polluted the agricultural environmental and influenced the agricultural sustainable development. The use of Photo-＆ bio-degradable mulching film could reduced the plastic film pollution fundamentally. The results showed that, Photo-and bio-degradable mulching films have the same function as the ordinary plastic film have. The photo-and bio-degradable mulching film enhanced the temperature and moisture content of soil and promoted crops growing effectively.
