【Abstract】 The experiment of applying different amount of chemical fertilizer with organic manure in soybean field has been conducted. The results showed that the ratio of soybean yield relying on soil was 74.9% -88.6%. After applying organic manure, the dependence of soybean yield on soil declined significantly. Sole application of organic manure, the soybean yield increased by 22.3%-33.6%, and on the base of chemical fertilizer combining with organic manure, the soybean yield increased by 12.7%-17.7% due to the effect of organic manure. Effects of the fertilizers on soybean yield increase resulted mainly from increasing the number of bean pods and grains.更多还原
