| 摘 要： | 在盆栽条件下,探讨了水肥互作对大豆部分生理性状、根瘤固氮及产量的影响.结果表明:肥料的施用及充足的土壤含水量有利于提高植株叶面积指数、根及地上部生物量,干旱(W1)及无肥(F0)条件限制了叶面积、根及地上部生物量的形成.相同水分条件下,未施肥处理(F0)根瘤数优于施肥处理(F1),土壤干旱(W1)限制了根瘤的形成与生物...

| Abstract: | Soybean yield are sensitive to soil moisture at flowering-podding growth stage(R1-R5).Fertilizer application may enhance the effect of soil moisture on yield of soybean,but few reports had focused on it.In this study,pot-experiments were carried out to investigate the effect of water-fertilizer coupling on physiological characteristics,nitrogen fixation by root nodules and yield of soybean.Three moisture levels and two fertilizer application levels were included in this experiment.The results showed that su... |
