草坪禾本科杂草的化学防除技术

Chemical Prevention and Eradication Technology on the Weeds of Gramineae in Lawn and Grassland

在 2 0 0 0～ 2 0 0 1年 2a间 ,用 6种禾本科除草剂对草坪禾本科杂草进行防除试验 ,结果表明 :禾耐斯作为芽前除草剂的效果比较好 ,对狗尾草、马唐、看麦娘和早熟禾的出芽抑制率均达到 10 0 % ;5种茎叶处理剂都是防除禾本科杂草十分有效的茎叶处理剂 ,对几种主要的禾本科杂草的防效都很高。

The prevention and eradication effects of six herbicide varieties (Acetochlor, Quizalofop-p-ethyl, Haloxyfop-(R), Clethodim, Qulalofop-p-ethyl) on the weeds of Gramineae were studied in the single sowing lawn of Zoysia matrella,Poa annua,Llium perenne,Zoysia japonica, and Dichondra micranthus. The results showed that Acetochlor could control the seeds of weeds of germinate effectively.The quantitative control efficiency of the five stem and leaf herbicides could reach a high level. These five herbicides can prevent the weeds of Gramineae efficiently.
