摘要
依据山东省13处灌溉试验站,1981～1986年冬小麦灌溉试验及土水势测试资料,分析了土壤水分特征曲线及不同生育阶段土水势与产量关系,提出了冬小麦各生育期适宜土水势及灌水下限指标,为冬小麦高产节水灌溉技术参数的确定提供依据。
The soil water characteristic curve and soil water potential in different growth stages and yield relations are analysed according to irrigation test for winter wheat and tension metric testing data of soil water from 1981 to 1986 in 13 irrigation test stations of Shandong Province.The optimal soil water potential in different growth stages for winter wheat and lower limit targets of irrigation are presented.The basis is provided for deter- mination of technical parameter of high yield of winter wheat and water-saving irrigation.
