研究了不同覆膜方式对旱作区冬小麦产量和水分利用率的影响。结果表明,在生育期降水量200.0mm下,全膜小垄沟穴播处理冬小麦平均折合产量4 615.4 kg/hm2,较露地条播增产42.9%,总产值、纯收入较露地条播分别增加3 599.9、1 998.1元/hm2;降水利用率64.5%,较露地条播降低0.9百分点;土壤水分利用率15.0 kg（/mm.hm）2,较露地条播增加5.0 kg（/mm.hm）2。
研究瞭不同覆膜方式對旱作區鼕小麥產量和水分利用率的影響。結果錶明,在生育期降水量200.0mm下,全膜小壟溝穴播處理鼕小麥平均摺閤產量4 615.4 kg/hm2,較露地條播增產42.9%,總產值、純收入較露地條播分彆增加3 599.9、1 998.1元/hm2;降水利用率64.5%,較露地條播降低0.9百分點;土壤水分利用率15.0 kg（/mm.hm）2,較露地條播增加5.0 kg（/mm.hm）2。

In this paper,we studied the effects of mulching with different kinds of plastic film on yield and water utilization efficiency of winter wheat,we concluded that under 200.0 mm conditions during the period of rainfall,the average yield was 4 615.4 kg/hm2 under hole sowing millet in small mulched with plastic film,and 42.9% higher than of the check that in the unmulched cultivatiom,the total output value and the net income increased 3 599.9 yuan/hm2 and 1 998.1 yuan/hm2,respectively;the utilization efficiency of precipitation reached was 64.5%,and 0.9 percentage point higher than of the check,the water utilization efficiency reached was 15.0 kg/（mm·hm2）,and 5.0 kg/（mm·hm2） higher than CK.
