中文摘要	通过在新疆巴州灌溉试验站进行的膜下滴灌棉花灌溉制度试验,得出了适合当地的常规滴灌制度。为进一步研究浅层地下水对灌溉的补偿效应,利用Hydrus软件对不同地下水埋深下膜下滴灌棉花生育期耗水量进行了模拟。通过引入关键点土壤含水率的概念,提出了膜下滴灌棉花受水分胁迫的标准。结果表明:地下水对棉花的耗水具有一定的补偿作用,地下水埋深越浅,则所需的灌溉定额越小。当地下水埋深小于1.5 m时,滴灌定额为3 300 m~3·hm~(-2);当地下水埋深为2.0 m时,滴灌定额为4 500 m~3·hm~(-2);当地下水埋深很大而对作物根区没有补给时,棉花完全依赖于灌溉所需的滴灌定额则为5 550 m~3·hm~(-2)。考虑到干旱区内具有较高的潜在蒸发势,会导致土壤的次生盐渍化,从而危及作物的生长,1.5~3.0 m的地下水埋深是灌区内较理想的水位区间。
英文摘要	Through the irrigation schedule experiment of drip irrigation cotton under plastic film in Korla Irrigation Experiment Station, Xinjiang, has obtained the suitable local conventional drip irrigation schedule. In order to further study the compensation effect of shallow groundwater to the irrigation, we use the Hydrus software to simulate the water consumption in growing stage of drip irrigation cotton under plastic film with different groundwater table. Through dwawing into the concept of key point soil water content, put forward the criterion of cotton water stress by the drip irrigation under plastic film. The results showed that: The ground water has a certain compensating function for the cotton water consumption, the shallower groundwater table, the smaller irrigation quota required. When the groundwater table was less than 1.5 m, the drip irrigation quota was 3300 m~3·hm~(-2). When the groundwater table was 2.0 m, the drip irrigation quota was 4500 m~3·hm~(-2). When the groundwater table was so biger and no any compensation, the cotton growth totally rely on the drip irrigation, the drip irrigation quota was 5550 m~3·hm~(-2). Consided the high evaporation potential in the arid area, it will cause the soil salinity to damage crop growth, the ground water table of 1.5 m to 3.0 m was the desired depth. This conclusion is not only the complementary and improvement to the conventional cotton irrigation schedule, but also this proposed method will have the guide and reference role for management and establishing the crop consumption quota of drip irrigation under plastic film in arid area.
