摘　　要：采用测坑试验研究液膜覆盖夏玉米对土壤温度、水分及产量的影响。结果表明:液膜覆盖使土壤储水能力增强,在0～40cm土层的土壤含水率显著提高;液膜覆盖的土壤增温效果明显,特别是中、低水分处理,增温7.4%左右;在百粒重和行粒数几项产量构成指标中,液膜覆盖较对照优势显著;液膜覆盖在玉米产量和水分利用效率上都有所提高,LFh、LFm和LFl处理的产量分别较对照提高了3.7%、35.4%和57.0%,WUEI分别较对照提高了3.6%、35.7%、57.1%,在WUEET指标上,分别较对照提高了5.3%、8.9%和9.2%。中、低水分的液膜覆盖处理更有利于玉米增产和水分利用效率的提高。The study measured the effects of liquid film mulching on soil temperature, moisture and yield of sum-mer maize field. Studies have shown that the soil water storage capacity in liquid film covering field increased, and in 0-40 cm layer of soil moisture content significantly increased. The soil temperature in liquid film covering field significantly increased, especially those of the intermediate and low-water treatment rose about 7.4 percent. The liquid film covering also had more significant advantage tha...
