空心莲子草的研究进展

Research advances of Alternanthera philoxeroides Griseb

空心莲子草(Alternanthera philoxeroides Griseb)是世界性的入侵物种,其生长迅速,抗逆性强,适应水生和陆生环境,利用宿根和地下茎越冬,通过营养器官进行无性繁殖,目前在我国很多地区滋生蔓延,危害严重。近年来,空心莲子草的生物防治越来越受到人们的重视。概述了空心莲子草的生物学特性和生理生化、防除方法等方面的研究进展,其中化学防除是我国防治空心莲子草的主要措施。同时,还介绍了空心莲子草综合利用方面的研究进展。

Alligator weed（Alternanthera philoxeroides Griseb） is a worldwide invasive species,which grows quickly with high resistance to adverse environment.It adapts to aquatic and terrestrial environments,which overwinters with underground roots and reproduces vegetatively.At present,it widely distributes in China and causes serious damage.The biological characteristics of control methods of A.philoxeroides were summarized.And chemical control is the main method to control this weed in China.Meanwhile,the utilization of A.philoxeroides were summarized.
