A pot experiment using root separation technique was conducted to further understand the effect of interaction played in intercropping system under different nitrogen levels.The results showed that and increasing application increased green leaf area per plant chlorophyll content soybean, but their effects gradually decreased with fertilization level.Root can improve photosynthetic characteristics only had a significant low level.The number bacteria, fungi, actinomycetes Azotobacteria also obviously affected by fertilization, presented changing trend first then improved soybean yield its components, activity interaction, significantly positively correlated plant, content, rate economic plant.Our indicate advantage will be partially inhibited an level.
