| 摘 要： | 2006年10月~2008年5月在山西省运城灌溉试验站进行了两年的冬小麦需水量和灌溉制度试验研究。结果表明,冬小麦的耗水规律为播种~越冬阶段0.48~1.11 mm/d;越冬~返青阶段0.14~1.07 mm/d;返青~拔节阶段0.69~2.10 mm/d;拔节~抽穗阶段2.02~4.27 mm/d;抽穗~灌浆阶段达到最大值3.57~8.62 mm/d;灌浆~收获阶段1.63~3.85 mm/d。冬小麦耗水量与产量呈抛物线关系,为了取得高产和较高的水分利用率,全生育期的耗水量应在380~440 mm之间。在当地气候、土壤及栽培模式下,冬小麦的灌溉制度为全生育期灌水3次,灌水定额60~80 mm,灌溉定额180~240 mm。

| Abstract: | From October in 2006 to May in 2008,effects of irrigation on the water consumption and yield of winter wheat were studied in Yuncheng's irrigation experiment station of Shanxi province.The results showed that consumptive water regularities of winter wheat were that water consumption was between 0.48 mm/d and 1.11 mm/d during the period from the sowing to the winter and spring,between 0.14 mm/d and 1.07 mm/d during the period from the winter and spring period to regreening,between 0.69 mm/d and 2.10mm/d duri... |
