中文摘要	针对甘肃陇东旱作雨养农业区的冬小麦产量低而不稳.水分利用效率低下,冬小麦夏季休闲期正值该区的降雨高峰期,降雨和无效蒸发同步且土壤保持水分不足的问题开展试验研究.通过夏季休闲期的地膜覆盖、集雨抑蒸,提高播前底墒,并对模拟底墒试验的产量、水分利用效率进行了研究分析得出:播前底墒对该区冬小麦产量和水分利用效率有显著的影响,通过提高底墒,对于稳定产量有较大贡献,提高生育期降水利用率,对提高产量有较大贡献.在分析多年研究资料的基础上,提出了该区冬小麦产量和播前土壤水分含量之间的模拟关系式以及冬小麦产量扣生育期降雨量之间的模拟关系式.
英文摘要	The summer fallow is meeting the rainy season and evaporation fastigium which brings the insufficiency of soil stored water in eastern of Gansu rain-fed areas.Cover with plastic film in this season that collecting water and restrain from evaporation could increase the water store in soil.A experiment that focus on the summer fallow time which bare soil cover with plastic film for restoring the rainfall in the soil,the results show: soil stored water before sowing and the growing season rainfall both are markedly influence the yield and WUE of winter wheat in this area.Cover with plastic film could increase the stored water more than 90% of rain in this season which greatly stably the winter wheat yield and improving the WUE,but more the growing season rainfall come into being higher yield.Based on more than 8 years testing results of plastic film mulching on this period,Simulate the relation of yield and soil stored water before sowing,the relation of yield and growing season rainfall.
