| 摘 要： | 依据中国农业科学院农田灌溉研究所2005-2006年度田间试验数据,研究了新乡地区冬小麦耗水量与产量的关系。结果表明,冬小麦全生育期耗水量与产量之间基本呈二次函数关系,经济灌水量为374.9mm,冬小麦适宜耗水量区间为374.9～551.7mm;采用Jensen模式,建立了冬小麦分生育期耗水量与产量的关系模型,模型中敏感指数的变化规律为:冬小麦在抽穗-灌浆期缺水敏感指数(λ)最大,对缺水最为敏感,拔节期次之,然后是苗期,而越冬期和返青期的敏感性最小。

| Abstract: | Based on the field experimental data of winter wheat in the Farmland Irrigation Research Institute of CAAS in 2005-2006,the relationship between crop yield and evaporotranspi-ration for winter wheat in Xinxiang district was studied. The results showed that the relationship between yields and water consumption in the whole growing period of wheat was Parabola model. The optimal irrigation amount was 374.9mm,and the interval amount of suitable water consumption was 374.9-551.7mm for winter wheat. In addition,... |
