摘要
论述了设施无公害蔬菜生产中杂草的发生危害特点及综合防治措施。设施无公害蔬菜中杂草防除首先应通过田间栽培管理进行防除,其次是物理防治,第三应选择高效、低毒、低残留的化学农药,同时大力发展生物除草剂的的研制及使用。倡导生物防治,结合物理防治、农业防治和化学防治等多种技术手段,在保障蔬菜产品绿色安全的前提下,使杂草危害降到经济阈值以下。
The occurrence,damage traits and integrated control measures of weeds in protected and pollution-free vegetables cultivation were reviewed.The field cultivation managements were firstly recommended.Followed closely were physical control and high-efficient and low toxicity chemical herbicides application.Additionally,bio-herbicides should be paid more attention to produce and applied.Totally,multiple ways including biological,physical,agricultural and chemical measures should be adopted synthetically to reduce the weeds damage level below the eco nomic threshold.
