Abstract
Under drip irrigation in the field,the influence of different irrigation water on soybean growth and yield was studied.In the case of the same irrigation frequency,test was set 4 irrigation treatment,irrigation quota were 30 mm、37.5 mm、45 mm、52.5 mm.Different growth stages of soybean plant height stem diameter and leaf area index were observed,and the value of theoretical yield and component of yield were also measured.The results showed that:plant height,stem diameter and leaf area index increase as irrigation water.Under the experimental conditions,by considering the yield and WUE,irrigation quota in the 300-360mm is more appropriate between the whole growth period.
