| Abstract: | Objective] The purpose was to explore the suitable planting density and fertilizer technology of summer soybean to obtain 3 000 kg/hm2 yield.Method] The quadratic regression orthogonal rotational combing design with four factors was used to study the effects of planting density and fertilizer on summer soybean yield,and find out the most optimized factors value.Result] All factors' effects on summer soybean yield was in order: Nitrogen fertilizer> phosphorus fertilizer> planting density> potassium fertilizer,and the best value range was: planting density 20.6×104-23.2×104 per ha,nitrogen fertilizer 83.5-95.2 kg/hm2,phosphorus fertilizer 57.1-73.1 kg/hm2,potassium fertilizer 43.0-52.0 kg/hm2.Conclusion] The study provides a scientific basis for integrating high yield cultivation technology of summer soybean. |
