中文摘要	针对聚乙烯地膜覆盖产生的农田残膜污染问题,探明新疆滴灌条件下可降解地膜覆盖在玉米上的应用效果。通过设置不同降解膜(M1:诱导期为100 d,黑色氧化生物双降解膜;M2:诱导期为80 d,白色氧化生物双降解膜;M3:诱导期为80 d,黑色完全生物降解膜;M4:诱导期为100 d,白色完全生物降解膜)和普通地膜(PE)共5种处理,研究降解膜覆盖对滴灌玉米土壤水温变化及生长的影响。结果表明:灌浆期前,各处理间土壤含水率无显著差异;灌浆期后,M2和M3处理21~40 cm平均土壤含水率较PE膜处理显著降低2.76%和2.89%,M1和M4处理与PE膜处理无显著差异。灌浆期至成熟期,4种降解膜处理各土层土壤平均温度与PE膜处理无显著差异。玉米苗期5~25 cm土层土壤温度日变化均呈现低-高-低变化趋势。相较于PE膜处理,生育前期降解膜处理对玉米株高、茎粗、叶面积指数和干物质积累量不产生显著影响,成熟期M1、M2、M3和M4处理的玉米株高分别减小3.09%、2.23%、2.50%和1.44%,干物质积累量分别减小0.87%、6.67%、2. 72%和2.29%。对照于PE膜处理,M1、M2、M3和M4处理的产量分别降低0.43%、 19.18%、5.74%和5.40%,水分利用效率分别降低1.09%、17.06%、5.42%和4.62%,其中M1处理与PE膜处理差异不显著。综上,诱导期为100 d的黑色氧化生物双降解地膜(M1)应用效果较好,可考虑在干旱区的生产实践中推广使用。
英文摘要	To solve the field remnant film pollution caused by polyethylene film mulching,and to explore the application effect of degradable film mulching on maize under drip irrigation in Xinjiang,we evaluated the effects of different degradable films (M1:black oxo-biodegradable film with 100 days induction period; M2:white oxo-biodegradable film with 80 days induction period; M3:black full-biodegradable film with 80 days induction period; M4:white full-biodegradable film with 100 days induction period) and conventional polyethylene film (PE) on soil moisture,temperature,and maize growth under drip irrigation. The results showed that various types of film had no significant effect on soil moisture until filling stage. After filling,M2 and M3 significantly decreased soil moisture in 21-40 cm soil layer by 2.76% and 2.89%,respectively. Compared with PE,and no significant difference was between M1,M4,and PE. Compared with PE,4 degradable film mulching treatments had no significant effect on soil temperature in 0-25 cm soil layer from filling to maturity stage. The daily variation of soil temperature in the 5-25 cm soil profile showed low-high-low trend at sowing.There was no statistical significance in crop height,stem diameter,leaf area index and dry matter accumulation between degradable film mulching and PE film mulching at early growth stage of maize . However,at maturity stage,compared with PE film mulching,M1,M2,M3,and M4 reduced crop height by 3.09%,2.23%,2.50%,and 1.44%,respectively,and reduced dry matter accumulation by 0.87%, 6.67%,2.72%,and 2.29%,respectively. Compared with PE,grain yield in M1,M2,M3,and M4 decreased by 0.43%,19.18%,5.74%,and 5.40%,respectively,and the water use efficiency decreased by 1.09%,17.06%,5.42%,and 4.62%,respectively,the difference between M1 and PE were not significant . Therefore,black oxo-biodegradable film with induction period of 100 d (M1) was considered as an effective agricultural practice to be widely applied in arid regions.
