摘　　要：[目的]为解决田间残膜给棉花产区带来的生态环境问题奠定基础。[方法]通过在石河子大学试验站的田间试验,探讨可降解地膜的降解性。[结果]填埋试验与地表覆盖试验结果表明埋深15-25 cm的可降解膜降解最快。与普通地膜相比,可降解膜能够起到一定的增温保墒作用。[结论]在棉花生产中可用可降解膜代替普通地膜,以缓解农膜残留造成的白色污染。[ Objective ] The research aimed to lay the foundation for solving the ecological environmental problem brought by residual film in the field in the producing area of cotton. [ Method] The degradability of degradable mulching film was discussed by the field experiment at the experiment station of Shihezi University. [ Result] The results of landfill test and ground - covering test showed that the degradability of degradable mulching film buried in the soil with the depth of 15 -25 cm was the fastest. Compared with common mulching film, the degradable mulching film had some temperature -increasing and moisture -conservation effects. [ Conclusion ] In the cotton production, degradable mulching film could be used to replace common mulching film, so as to relieve the white pollution brought by residual film.
