摘　　要：为了探讨液体地膜覆盖对小麦和玉米生产的调控作用,通过对比试验,研究了液体地膜覆盖对小麦、玉米的产量构成因素和水分利用效率WUE的影响。结果表明:与对照不覆膜相比,液体地膜覆盖有利于小麦、玉米产量的提高,小麦在80%、70%和60%灌水下限(田间持水量的80%、70%、60%)处理情况下产量分别提高了6.12%、24.17%、35.67%,水分利用效率提高了10.43%、29.00%、38.01%;玉米在80%、70%和60%灌水下限处理情况下产量分别提高了3.48%、1.48%、3.79%,水分利用效率提高了6.56%、6.85%、10.46%。Through the contrast test,The eftects of liquid film mulching on wheat and corn on yield structure and water use efficiency （WUE） was analyzed. The results show that liquid film mulching benefits to increase yield of wheat and com. To wheat, the yield is increased 6. 12% , 24.17% and 35.67% respectively in the cases of 80%, 70% and 60% field capacity, and water use efficiency is increased 10.43% , 29% and 38.01%. To maize, the yield is increased 3, 48% , 1.48% and 3.79% respectively in the cases of 80% , 70% and 60% field capacity, and water use efficiency is increased 6.56%, 6.85% and 10.46%.
