Abstract: To investigate the application effect of different soil amendment combination of planosol, under field conditions, seven treatments were designed to study the effects of the biological fertilizer, organic fertilizer and lime on planosol nutrient change and yield and quality of soybean. The results indicated that: compared with conventional fertilization, treatment with different soil amendment improved the plant height, dry matter weight at different development stages of soybean, significantly improved the soybean grain number and number of pod, but had no obvious effects on 100- grain weight. Different soil amendment application could improve soybean production and the range of increase in yield was 9.7 % to 25.6 % , and the difference reached significant level. The contents of soil available nutrient and pH were increased, soil chemical properties were improved; the soybean protein and fat contents were increased, and soybean quality was improved. Different soil amendment combination mixed application was better than single application. In conclusion, on the basis of the above analysis, biological fertilizer + organic fertilize treatment and lime + organic fertilizer treatment were good soil amendment combination.
