摘　　要：在滴灌的条件下,通过设置不同的施肥量,研究其对大豆干物质积累、株高及产量的影响。结果表明:氮、磷、钾三种元素合理搭配施用,大豆的生物量和产量等达到最佳效果,通过二次回归方程分析,得出大豆膜下滴灌经济施肥量为氮(N)78 kg/hm^2、磷(P2O5)76 kg/hm^2、钾(K2O)86 kg/hm^2;产量为3 434~3 536 kg/hm^2。Effects of different fertilization rate on dry matter accumulation, plant height and yield under drip irrigation of soybean were studied in the paper.The results showed that the biomass and yield of soybean was best when the optimum fertilizing quantity of soybean under drip irrigation was N 83.8 kg/ha, P2O5 93 kg/ha, K2O98.7 kg/ha,and the yield was 3434-3536 kg/ha.
