棉田恶性杂草田旋花研究进展

Review of Field Bindweed,Convolvulus arvensis L.,a Troublesome Weed in Cotton Fields

作为恶性杂草之一,田旋花具有极强的环境适应能力及强大的繁殖和再生能力,在我国三大棉区广泛分布,严重危害棉田生态系统。本文概述了目前国内外在田旋花的形态特性、分类学特征、分布与生境、生活史、经济学特性及防除策略等方面的研究进展,并针对我国田旋花发生为害情况,提出了深入研究田旋花地下根系繁殖特性、区域环境适应性及高效防除技术的建议。

Field bindweed(Convolvulus arvensis L.),known as one of the ten most noxious weeds in the world,has a considerable ability to adapt to the environment and to reproduce and regenerate.In recent decades,field bindweed has increasingly become a problematic weed of cotton fields in China.This review summarizes research to-date on this weed,including morphological and taxonomic characteristics,distribution and habitat,life history,economic characteristics and control strategy.Based on the analysis of the occurrence and harmfulness of field bindweed in China,we suggest carrying out further research on the reproductive characteristics of perennial root systems,adaptability to regional environments and high-efficiency control technologies for field bindweed.
