With the improvement of the rhizosphere research methods, more and more researches have been done on the interactions between the crops and the underground species, the rhizosphere effects and the root distribution. Due to the spatial heterogeneity of root distribution and interactions between root systems, the root growth status changes, affecting the absorption and transfer of crop nitrogen, and affecting crop nutrient utilization and yield. Beijing Bopute discussed the effects of root interactions on nitrogen uptake by crops in wheat/maize intercropping, and found that the amount of nitrogen uptake in crops that were not segregated was higher than that of segregation treatment. The soil nutrient tester studied the nitrogen absorption and utilization of wheat-corn-soybean and wheat-maize-sweet potato intercropping system. The results showed that the biomass and nitrogen uptake that were not separated under both systems were higher than that of the complete separation. And using the 15N labeling method, 15N of soybean was transferred to corn, and 15N between corn and sweet potato was transferred from corn to sweet potato, indicating that the maize-soybean intercropping system had a significant nitrogen-saving effect.
After careful study of soil nutrient by soil nutrient tester, the advantage of corn-soybean intercropping compared with corn-sweet potato intercropping system has been confirmed. However, it has been confirmed that the interaction between crops on the ground and the plant material accumulation and light contract The mechanism of the effects of chemical transformation to explain its mechanism has not yet been reported.
