| 摘 要： | 采用最小二乘法和线性规划法对蚕豆水分生产函数与灌溉定额进行了研究.结果表明:在地面灌溉条件下,蚕豆产量与耗水量呈二次函数关系;蚕豆在拔节-开花,开花-结荚2个生育期对缺水最为敏感;蚕豆经济灌溉定额为2 400 m3/hm2,在苗期-拔节、拔节-开花、开花-结荚、结荚-成熟4个生育阶段,最优分配灌溉定额依次为675、750、975 m3/hm2.

| Abstract: | Broad bean′s water production function and irrigation quota were studied with least squares and linear programming method.The results indicated that there was a quadratic function relationship between broad bean's yield and water consumption in ground irrigation condition.Broad bean was very sensitive to water shortage in jointing-flowering and flowering-burliness stage.Broad bean's economic irrigation quota was 2400 m~(3)/hm~(2),and irrigation quota in broad bean's four periods of duration was 675,750,975,0 m~(3)/hm~(2),respectively. |
