| 摘 要： | 连作障碍问题的发现已有上千年的历史,但对其发生机理和克服措施还没有取得突破。本文分析了植物次生代谢物的种类及其产生机理、次生代谢物的自毒作用、植物对自产的次生代谢有毒物质的抗性机制及其形成时序等,认为次生代谢物对新生植物的自毒作用是连作障碍发生的关键因素之一,并在此基础上提出了克服连作障碍的几种途径。

| Abstract: | Continuous cropping obstacle is an archaic problem discovered and known by Chinese forefathers thousand years ago.However,its mechanism was poorly understood,and subsequently no effective measures could overcome it.In this paper we analyzed the kinds and synthesizing mechanism of secondary metabolite,secondary metabolite autotoxic,the mechanisms of resistance to self-produced toxic secondary metabolites and the formation time in plants.We propose that secondary metabolite autotoxic to renascent plant is the... |
