根际养分活化与吸收过程的定量模拟研究进展

Development of Studies on Modelling the Prccers or Root-Induced Nutrient Activation and Absorption

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．

Based on the studies on root-mediated eclats of root system as a active sink of nutrients on nutrient availability and absorption, this paper reviewed the process of nutrient nutrient induced by PH changes, chelates. reducing substances and microbes in rhizosphere. This review focussed on the current progress and developing trend of research onmodelling the process.
