外来种空心莲子草的入侵及其克隆特性综述

Advance in invasion and clonal characteristics of the alien species Alternanthera philoxeroides

空心莲子草是一个入侵的恶性杂草,在我国诸多地区滋生蔓延,严重影响农业生产和生态系统安全。目前对于空心莲子草的入侵机制和防治等研究集中于生理和生物学研究,但其防治未产生较好的控制效果。本文梳理了空心莲子草的生物学特性和空心莲子草在各种环境因素的影响下所表现出来强入侵特性与克隆性,总结了目前对于空心莲子草的防治方式,并提出今后空心莲子草的入侵研究需重点考虑其克隆特性的影响,以期对空心莲子草的入侵机制深入研究提供理论参考。

Alternanthera philoxeroides,as an invasive and malignant weed,is growing and spreading in many areas of China,which seriously affects agricultural production and ecosystem safety.At present,the research on the invasion mechanism and prevention and control of A.philoxeroides is focused on physiological and biological research,but its prevention and control has not gained a good control effect.This paper has sorted out the biological characteristics of A.philoxeroides under the influence of various environmental factors,strong invasion characteristics and clonal traits.We summarized the current way of prevention and control of A.philoxeroides,and put forward the future research needs to consider the connections between invasions and clonal characteristics in order to provide some theoretical implications for the invasion control of A.philoxeroides.
