新疆列当种类、危害与防治现状

Review of the species,hazard and management status of Orobanche L.in Xinjiang

列当是一种根部全寄生恶性杂草,影响作物生长,对农业生产造成了巨大破坏。目前,列当防治措施主要包括轮作、种植诱捕作物、化学防治等,但尚无适用于大部分地区及作物的有效防治措施。本文综述了新疆列当种类、寄生特点、危害和目前采取的防治措施,并对列当的萌发刺激物、防治机理和化学除草剂在大田应用提出展望,以期为新疆相关防治工作提供参考。

Orobanche spp.are holoparasites plants deriving all of their nutrients from host plant roots,affecting the growth of crops and causing great damage to agricultural production.At present,the control methods of Orobanche spp.are mainly rotation,planting trap crops,chemical management and etc.,but there are no effective control measures suitable for most areas and crops.This paper reviewed on species,hazards and current management methods of Orobanche,and put forward the prospect on application of germination stimulant,prevention and control mechanism and herbicide in field,so as to provide reference for research and control this kind of weeds in Xinjiang.
