在论述植物根系作为养分的主动吸收槽．对根际养分生物有效性产生重要作用的前提下，本文扼要讨论了根际pH值变化、根分泌螯合物与还原性物及根际微生物在根际土壤养分活化中的作用过程，并重点评述了有关养分活化与吸收模拟模型的研究进展与发展趋势．
In the discussion of plant roots as the active absorption tank. On the premise of the important role of rhizosphere nutrient bioavailability, this paper briefly discussed the rhizosphere pH changes, the role of root exudation chelates and reducing substances and rhizosphere microorganisms in the activation of rhizosphere soil nutrients, and focus The research progress and development trend of nutrient activation and absorption simulation models are reviewed.
