摘 要:通过桶栽冬小麦的再生水灌溉试验,探讨了不同再生水灌溉制度对冬小麦生长发育的影响,分析了再生水灌溉制度和产量的关系。结果表明,不同再生水灌溉制度下,冬小麦全生育期耗水量(281.3~348.1mm)和日耗水量(1.3~1.6mm)变化不大,冬小麦水分生产率变化(0.9~1.9kg/m3)较大;播前及全生育期采用2/3清水+1/3再生水混灌时,对冬小麦生长发育有一定的促进作用,冬小麦产量比清水灌溉处理提高42.1%;纯再生水灌溉和半再生水半清水混灌不利于冬小麦的生长发育。Based on the barrel experiments of winter wheat under reclaimed water irrigation, the effects of reclaimed water irrigation programs on growth and yield were studied. The results showed that with different reclaimed water irrigation programs, water consumption of the whole growth period and every day both had little change, ranging from 281.3 to 348.1 mm and from 1.3 to 1.6 mm respectively; but the water productivity had larger changes, ranging from 0.9 to 1.9 kg/m3 ; the presowing irrigation and whole growth period irrigation using 2/3 clean water +1/3 reclaimed water could improve yield by 42.1% compared to clean water irrigation, and the completely reclaimed water irrigation and the 1/2 reclaimed water q- 1/2 clean water irrigation had adverse effects on the growth of winter wheat.
