人参连作障碍及防治措施研究进展

Research Progress on Consecutive Monoculture Problems and Control Measures of Panax Ginseng

人参种植对土壤要求严格,长期连年种植易发生烧须、烧根、土传病害频发等连作障碍问题,大大降低了人参的产量和品质。通过查阅大量人参栽培文献,综述了人参产生连作障碍的主要原因,以及防治人参连作障碍的主要措施。该文主要从连作人参土壤理化性质劣变、土壤微生物群落变化、化感自毒作用等方面介绍了人参连作障碍机制的研究进展,并从农业防治、化学药剂防治、生物防治等方面介绍了人参连作障碍防控的研究进展,旨在为研究人参连作障碍机理和建立克服连作障碍的技术奠定基础。

Panax ginseng cultivationrequires strict soil requirement.Consecutive monoculture problem such as root burned and root hair burned would appear while long-term cultivation,which reduced the yield and quality of Panax ginseng.According to large literature review,main reasons for the continuous cropping obstacles and main prevention measures for consecutive monoculture in ginseng were summarized.Deterioration of soil physical and chemical properties,the change of soil microbial community,and autotoxic effect for ginseng consecutive monoculture problem,as well as agricultural control,chemical control,biological control for controlling consecutive monoculture problem were summarized and reviewed for future researching on the mechanism ginseng consecutive monoculture problem and technology establishmentfor overcoming difficulties.
