摘要
在大田滴灌条件下,研究了不同灌水量对复播大豆生长和产量的影响。在灌水次数相同的情况下,试验设置了4个灌水处理,灌水定额分别为30mm、37.5mm、45mm、52.5mm;观测了复播大豆不同生育阶段的株高、茎粗和叶面积指数;测量了复播大豆的理论产量及构成因素的数值。试验结果表明:复播大豆株高、叶面积系数、茎粗随着灌水量的增加而增加;在本试验条件下,综合考虑产量和水分利用效率,复播大豆生育期内灌溉定额在300-360mm较为适宜。
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.
