本文论述了药用植物化感自毒的概念、作用机制和作用方式。研究认为，药用植物连作障碍和化感自毒的根本原因是自毒化感化学物质与药用活性物质的同源性。在此基础上，分析了这些障碍的成因与药用植物化感物质的自毒性之间的关系。利用DGGE、T-RFLP等相关技术，提出了基于根际土壤微生物区系研究的综合农艺方法。这减少了in-
In this paper, the concept, mechanism and action mode of allelopathic autotoxicity of medicinal plants were discussed. The study identifies that the basic reason for the continuous cropping obstacles and allelopathic autotoxicity of medicinal plant is the homology of autotoxic-allelochemicals and pharmaceutical active substances.Accordingly, the relationship between the causes of the obstacles and the autotoxicity of allelochemicals in medicinal plants are also analyzed. Comprehensive agronomic methods based on rhizospheric soil microflora systems research using DGGE, T-RFLP and other related techniques are proposed. This reduces the in-
