中文摘要：

针对西瓜／棉花间作种植模式，对比分析了滴灌、沟灌灌水方式下间作作物生长状态、耗水规律、产量及水分生产率等的变化。结果表明，对于西瓜／棉花间作种植模式，膜下滴灌灌水方式优于沟灌灌水方式；膜下滴灌处理群体叶面积指数大于沟灌处理；对于间作西瓜，共生期内膜下滴灌处理较沟灌节水62．9mm；对于间作棉花，全生育期内滴灌处理较沟灌节水129．9mm；滴灌处理下西瓜产量、棉花籽棉产量、间作水分生产率较沟灌提高了14．9％、9．2％、40．39％。在研究区，瓜棉间作种植模式采用膜下滴灌灌水方式对农业生产有积极的推进作用。

英文摘要：

The effects of drip irrigation and furrow irrigation on growth, yield, water consumption, and water productivity （WP） in the watermelon-cotton intercropping system were analyzed. The results showed that drip irrigation with mulch was better than furrow irrigation for the watermelon-cotton inter- cropping system. Compared to the furrow irrigation, the leaf area index of drip irrigation treatment was greater, whose irrigation amounts were reduced by 62.9 mm in the symbiotic period for watermelon and 129.9 mm during the whole growth stage for cotton. The watermelon yield, cotton yield and WP under drip irrigation increased by 14.9%, 9.2% and 40.39% compared to furrow irrigation, respectively. Drip irrigation with mulch had a greater advantage to develop agricultural production in the watermelon-cotton intercropping system.
