对滴灌条件下夏棉水肥耦合效应进行了田间试验。结果表明：根据夏棉不同生育阶段的需水特征和土壤水分状况，可分别采用滴灌和畦灌方式，比常规棉田畦灌节水23．3％～28．7％；对于中等肥力的棉田，在每hm2施纯氛300kg的范围内，随施肥量增加皮棉产量呈增加的趋势，在每hm2施纯氮150～225kg区间内，其产量增加较快。
A field experiment was conducted on the coupling effect of water and fertilizer on summer cotton under drip irrigation. The results showed that: According to the characteristics of water requirement and soil moisture at different growth stages of summer cotton, drip irrigation and tillage irrigation were adopted respectively, saving 23.3% -28.7% hm2 application of pure atmosphere within the range of 300kg, with the increase of fertilizers, lint yield tends to increase, yield per hectare of pure nitrogen in the range of 150 ~ 225kg, the output increased rapidly.
