摘　　要：在不施肥夏大豆产量170kg/667m2左右的生产条件下,夏大豆施用惠满丰有机复混肥20-60kg/667m2,增产大豆45-7-102.3kg,平均77.5kg,其增产幅度为27.0％-60.4％,平均45.8％;在等养分量情况下,惠满丰有机复混肥较化肥增产17.9％;惠满丰有机复混肥的适宜用量为40kg/667m2.惠满丰有机复混肥对夏大豆的增产原因主要有:促进生长,有利于干物质积累,改善结实性状,协调产量构成因素等.Under the production condition that summer soybean output nearly 170kg·667m-2without fertilizer,applying Huimanfeng organic compound-mixing manure 20-60kg·667m-2 can increase the output by 47. 5-102. 3kg, the amount of average is 77. 5kg , the range of increasing is 27.0% -60.4%, with an average of 45.8%. Under the condition of equal amount of soil nutrient, the Huimangfeng organic compound-mixing manure can increase the output 17.9% , compared with chemical fertilizer. The optimum application amount of Huinmanfeng is 40k$·667m-2. The main reason of increasing output of Huinmanfeng is promoting growth, beneficial to accumulaling dry, improving the character of fruiting , bring the factor of output into the line etc.
