摘要:【目的】探索半湿润区沟垄覆盖栽培条件下冬小麦田的蓄水保墒效果和增产增收效应。【方法】采用
普通地膜、液体地膜和秸秆设置不同沟垄覆盖栽培模式,连续 3 年对冬小麦土壤水分、产量、水分利用效率和经
济效益进行分析研究。【结果】在冬小麦全生育期,垄覆地膜沟覆秸秆的蓄水保墒作用最为明显,能有效改善土
壤的水分利用状况。垄覆地膜沟覆秸秆和垄覆液膜沟覆秸秆的产量最高,3 年平均产量分别较平作不覆(CK 1)提
高 %(P<)和 %(P<),较垄不覆沟不覆(CK 2)提高 %(P<)和 %(P<),
WUE平均分别较CK 1提高 %(P<)和 %(P<),较CK 2提高 %(P<)和 %(P<)。
下,垄覆地膜沟覆秸秆、垄覆液膜沟覆秸秆是半湿润区小麦旱作的高效栽培模式。

Abstract:【Objective】The objective of the experiment was to explore the effect of soil water conservation, grain yield and
e increments of winter wheat under different furrow-ridge mulching cultivation conditions in semi-humid area . 【Method】
Different cultivation patterns of furrow-ridge mulching were designed using ordinary film, liquid film and straw and soil moisture,
yield, water use efficiency and economic benefits of winter wheat were analyzed for three years.【Result】When treated with ordinary
film and straw dual-mulching, it had obvious effect of keeping moisture during the whole growth period of winter wheat, which
could effectively improve the soil water utilization. In three years, the ordinary film and straw du
