中文摘要	在大田滴灌条件下研究普通地膜、降解地膜覆盖对土壤水分、温度及对玉米生长的影响。结果表明，玉米生育期内普通地膜和降解地膜处理的保墒效果显著高于不覆膜(对照)，但无明显差异，两种地膜覆盖处理的保墒效应主要表现在明显提高玉米营养生长阶段0～60 cm土壤含水量；地膜覆盖明显提高苗期至拔节期5～25 cm土壤平均温度，降解地膜与普通地膜分别比对照提高1.81℃和2.80℃。降解地膜和普通地膜处理营养生长阶段叶面积指数和光合势处于较高水平，其地上部干物质积累比例分别占总干重的54%和55%，显著高于对照。降解地膜和普通地膜处理的子粒产量分别比对照提高了20.9%和21.6%，水分利用效率分别提高了20.6%和20.9%，均显著高于对照。因此，在滴灌条件下降解地膜与普通地膜具有较好的提温保墒效果，显著提高玉米营养生长阶段的干物质积累和子粒产量。
英文摘要	A field experiment was conducted in semi-arid farming area in west of Jilin province to explore the effects of covering plastic film and degradable film on soil water, soil temperature and corn growth. The results indicated that plastic film and degradable film mulching mainly improved the soil moisture in the soil layer of 0 -60 cm at the vegetative growth stage, there was no remarkable difference between the two mulching treatments in the whole growing period under drip-irrigation. The average soil temperature in 5 -25 cm soil layer under plastic film and degradable film mulching were 2.80 ℃ and 1.81 ℃ respectively, and higher than that of control respectively from emergence to jointing stage. Related to the higher leaf area index(LAI) and leaf area duration(LAD) of mulched by degradable film and plastic film in vegetative phase, their above-ground dry matter of vegetative phase at the ratio of whole growing season were 54% and 55% significantly higher than the control. Compared with the control, the grain yield with plastic film and degradable film significantly increased by 21.6% and 20.9% respectively, and the water utilization efficiency clearly increased by 20.9% and 20.6% respectively(p < 0.05). Therefore, it is similar to the plastic film mulching, the degradable film mulching great improving soil moisture, soil temperature, the dry matter weight during the vegetative growth period and grain yield under drip-irrigation conditions in semi-arid region.
