Although consecutive monoculture problems have been studied for many years, no effective treatments are currently available. The complexity of systems triggered the formation of consecutive monoculture problems was one major cause. This paper elaborated the physiological and ecological mechanisms of consecutive monoculture problem formation based on the interaction relationship among multiple factors presented in the rhizosphere soil of consecutive monoculture plants. At same time, in this paper the multiple interactions among cultivated medicinal plants, autotoxic allelochemicals and rhizosphere microbial were proposed to be most important causes that derived the formation of consecutive monoculture problem. The paper also highlighted the advantage of 'omics' technologies integrating plant functional genomics and metabolomics as well as microbial macro-omics in understanding the multiple factor interaction under a particular ecological environment. Additionally, taking R. glutinosa as an example, the paper reviewed the molecular mechanism for the formation of R. glutinosa consecutive monoculture problem from the perspective of the accumulation of allelopathic autotoxins, the rhizosphere microecology catastrophe and theresponding of consecutive monoculture plants. Simultaneously, the roles of mutilple 'omics' technologies in comprehending these formation mechanism were described in detail. This paper provides finally a new insight to solve systematically the mechanism of consecutive monoculture problem formation on molecular level.
尽管连作障碍问题已研究多年，但目前仍无有效防治措施。连作障碍问题形成的系统复杂性是一个主要原因。本文基于连作植物根际土壤中多种因素的相互作用关系，阐述了连作障碍问题形成的生理生态机制。同时，本文提出栽培药用植物、自毒化感物质和根际微生物之间的多重相互作用是导致连作障碍问题形成的最重要原因。本文还强调了整合植物功能基因组学和代谢组学以及微生物宏组学的“组学”技术在理解特定生态环境下多因素相互作用方面的优势。此外，以地黄为例，本文从化感自毒物质积累、根际微生态灾难及连作植物响应等方面综述了地黄连作障碍问题形成的分子机制。同时，详细描述了多种“组学”技术在理解这些形成机制中的作用。本文最终为系统解决分子水平上连作障碍问题形成机制提供了新的见解。
