摘要
在大田试验的基础上，分析了膜上灌小麦的水量平衡、土壤剖面水分分布特征、产量水平以及生理指标的日变化，研究结构表明在渭北旱塬区应用膜上灌技术可以减小土壤水分无效蒸发、改变土壤剖面水分分布特征、增加土壤水分贮量、调节作物生长微环境，从而提高作物产量。
On the basis of field experiment,water balance,moisture distribution property in soil profile, yield,and diurnal change of physiological indexes of wheat of film hole irrigation are analyzed.The results show that in Weibei dry plateau using film hole irrigation technique can decrease soil moisture evaporation,change moisture distribution in soil profile property,increase soil moisture storage,adjust crop growth micro environment,and then increase crop yield and should be popularized in large area.
