间作促进磷吸收利用的研究进展OA北大核心CSTPCD

The application of phosphate fertilizer and mineral weathering are the main sources of soil phosphorus,but the low utilization rate of phosphorus and the limited ability of crops to absorb and utilize phosphorus lead to the accumulation of soil phosphorus,which limits the growth of crops.Intercropping system can improve soil phosphorus availability.The effects of intercropping on phosphorus utilization rate were summarized.The mechanism of intercropping to improve soil phosphorus availability was reviewed from three aspects:soil microorganisms,crop roots,and changes in endogenous hormones.It is suggested that in the future,we should focus on the in-situ characterization of plant root morphology,auxin-related gene expression,soil microorganisms and related functional genes,in order to provide reference for improving phosphorus utilization rate through intercropping.
