摘　　要：[目的]研究不同生物降解膜在新陆早61号上的应用效果。[方法]开展3种生物降解膜在棉花新陆早61号上的田间比较试验,针对3种生物降解膜的地温、降解膜降解性能和新陆早61号的农艺性状及经济性状进行综合分析,旨在筛选出适合兵团棉花生产利用的降解膜产品。[结果]降解膜的厚度越厚降解越早,厚度越小降解速率越快。3种供试生物降解膜与普通地膜相比延缓了新陆早61号各生育期的生长发育,在出苗期至现蕾期增温效果比普通地膜差;同时植株的生长势减弱,叶面积指数降低,群体收获株数减少,结铃减少,产量不同程度的减少。[结论]3种供试生物降解膜都能降低土壤地膜残留,有效地减少了残膜对土壤的污染。[ Objective ] To study the application effect of different biodegradable film on Xinluzao 61. [ Method ] Comparative test of 3 kinds of biodegradable film in the field were analyzed. To select degradable film products suitable for production by corps cotton by comprehensively ana-lyzing ground temperature , degradation property of 3 kinds of biodegradable film and agronomic traits and economic traits of Xinluzao 61. [ Re-sult] The thicker the degradation film was, the earlier the degradation was, the smaller the thickness was, the faster the degradation rate was. Compared with ordinary plastic film,3 kinds of biodegradable film delayed the growth period of Xinluzao 61. From the seedling stage to squaring stage,the effect of temperature raising was worse than that of ordinary film. At the same time,the growth potential was reduced, leaf area index decreased,the population number of harvested plants and boll number were reduced. The yield decreased in different degrees. [Conclusion] 3 kinds of biodegradable film can reduce soil film residue and effectively reduce the pollution of residual film to soil.
