| 摘 要： | 通过大田试验,在甘肃秦王川灌区研究了调亏灌溉下蚕豆的产量、水分利用效率和经济效益,发现在苗期或拔节期轻度缺水条件下(土壤含水率为田间持水量的60%～65%),比充分灌溉条件下(土壤含水率为田间持水量的70%～75%)蚕豆增产14.05%和9.09%,节水10.92%和4.14%,经济效益提高16.16%和21.94%.因此认为,苗期或拔节期轻度水分亏缺是蚕豆调亏灌溉的适宜调亏时期和适宜调亏程度.

| Abstract: | Based on field experiment,the effect of regulated deficit irrigation on yield,water use efficiency and economic benefits of broad bean were studied in Qinwangchuan irrigation region.The results showed that the yield of broad bean increased 14.05 % and 9.09 %,saved water 10.92 % and 4.14 % and increased economic benefits 16.16 % and 21.94 %(soil moisture maintained at 60 %～65 % of field capacity)by light water deficit in seeding or jointing compared with full irrigation treatment(soil moisture maintained at 70 %～75 % of field capacity).So the light water deficit in seeding or jointing can be considered the optimum deficit stage and deficit degree. |
