摘　　要：针对江苏淮北地区冬小麦既要灌溉又要排水的生产实际 ,探索塑料暗管排水和渗灌的效果 .试验结果表明 ,塑料暗管在小麦生育期间通过有控制的灌溉和排水 ,能起到保墒、增温、节水和降渍的作用 。The effect of drainage and seepage irrigation by plastic subpipes is investigated based on the production practice of winter wheat in the North Huai River of Jiangsu province where not only drainage but also irrigation is needed. Results show that plastic subpipes play an important role in retaining soil moisture, increasing temperature, saving water and reducing waterlogging, thus significantly raising winter wheat yield.

关 键 词：塑料管道 冬小麦 土壤水分调控 节水 暗管排灌
