摘    要:在干旱的新疆乌鲁木齐采用人工控水试验,研究了调亏灌溉对膜下滴灌棉花生长发育和最终产量以及水分利用效率的影响。结果表明,要获得较高的产量和水分利用效率,膜下滴灌棉花全生育期内的灌水量应控制在450 mm左右;适时适度的水分亏缺虽然降低了总生物量,但由于作物的亏水补偿效应不但提高了生殖器官在总生物量中的分配比例,而且有利于光合产物向经济产量的转移,水分利用效率明显提高;适时适度的亏水处理1,其最终收获产量和水分利用效率比充分供水的对照处理提高了1.7%和17.0%。实现了以农田水分管理来调控光合产物的分配,减少作物的生长冗余,提高了农业水资源的利用效率。

关 键 词:调亏灌溉  水分胁迫  膜下滴灌  棉花

Abstract:Effects of Regulated Deficit Irrigation(RDI) on growth,yield and water use efficiency of cotton with drip irrigation under mulch were tested through artificial water control experiment in Urumqi,Xinjiang province.The results showed that want to obtain both high cotton yield and high water use efficiency will need irrigated about 450 mm.Although the proper time and moderate water deficit reduce the total biomass,it not only improved reproductive organs growing but beneficial to distributed from photosynthate...
Keywords:regulated deficit irrigation  water deficit  drip irrigation under mulch  cotton
