中文摘要	为了探明降解膜在哈密盆地滴灌棉花种植的应用效果,选取降解膜M1,M2,M3,M4及普通塑料地膜PE(CK)开展对照试验,研究降解膜的降解性能及其对滴灌棉花土壤水热变化与产量的影响.结果表明: M2在覆膜80 d左右最早出现降解、180 d左右进入残存期,生育期末仍有小块地膜残片存在;而降解膜M1与M3于生育期末才进入崩解期,降解相对缓慢;普通塑料地膜始终没有降解.苗期和蕾期各种降解膜尚未开始降解,保温保墒性能与CK相似;花期以后各种降解膜出现了不同程度的降解,花期降解膜与普通塑料地膜覆盖的土壤平均温度差异最大,降解膜M1,M2,M3及M4的土壤平均温度分别比CK低11.62%,10.02%,7.67%及10.45%,而铃期和吐絮期土壤温度差异较小,降解膜土壤平均温度比CK仅低2.05% ~ 5.52%;花期到吐絮期降解膜M1,M2,M3及M4处理的土壤平均质量含水率分别比CK低5.92%,8.09%,7.14%及12.41%,保墒性能差异较大;降解膜处理的籽棉产量较CK减产2.05%~13.72%,其中降解膜M2产量仅次于CK,且与CK之间无统计学意义.因此,无色透明氧化-生物双降解膜M2替代普通塑料地膜用于哈密盆地等极端干旱区棉花生产实践具有可行性.
英文摘要	In order to explore the application effect of degradation film on cotton planting under drip irrigation in Hami basin,four different degradation films (M1,M2,M3 and M4) were selected. The common plastic mulch PE was used as the control (CK) to carry out control experiments to analyze the degradation performance of different degradation films and its influence on soil hydrothermal,heat change,and yield of cotton under drip irrigation. The results showed that the earliest degradation occurred on M2 around 80 days after mulching. M2 entered the survival stage on day 180 after mulching together with M4. There were still small pieces of plastic film at the end of growth period. However,the degradable films M1 and M3 only entered the disintegration at the end of growth period,while the plastic mulch did not degrade all the time. In the seedling stage and bud stage,all kinds of degradation films have not yet begun to degrade, and the performance of heat preservation and moisture preservation was similar to CK. After florescence stage,all kinds of degradation films showed different degrees of degradation,and the difference of average soil temperature between degradable film and common plastic film was largest. The average soil temperature of degradation film M1,M2,M3 and M4 was 11.62%,10.02%,7.67% and 10.45% respectively,lower than that of CK,while there was little difference between boll stage and boll opening stage. The average soil temperature of degradation film was 2.05%-5.52% lower than that of CK at boll stage and wadding stage. The average soil mass moisture content of M1,M2,M3 and M4 treatments were 5.92%,8.09%,7.14% and 12.41% respectively, lower than that of CK,as the great difference of soil moisture retention performance is large. The yield of seed cotton treated with degradable film was 2.05%-13.72% lower than that of CK,and the yield of degraded film M2 treated with degradable film was second only to that of CK. Therefore,it is feasible to replace the common plastic mulch with the colorless transparent oxidization-biodegradable film M2 in the cultivation practice of cotton in extreme arid regions such as Hami basin.
