| 摘 要： | 用草甘膦喷洒灌草丛草场灌木和半灌木对其防除效果及再生性进行了试验观察。结果表明，施药浓度０．０５％以上时，半灌木死亡率１００％；浓度０．５％以上时，灌木死亡率８５％以上，７５ｄ后无再生植株，１２０ｄ后，浓度０．５％以上时，无再生植株，浓度０．１５和０．０５％时再生植株分别为１株和３株，占观察数的４％和１２％。

| Abstract: | The effect of glyphosate in controlling bushes and semi bushes on shrub grassland was examined in this study.It was observed that a glyphosate solution of 0.05% or higher concentration can kill all semi bushes;a solution of 0.5% or higher can kill 85% of bushes,with on re growth observed in 120 days after glyphosate application;the rate of re growth of bushes in 120 days after glyphosate spraying was 4% and 12% respectively for the cases of 0.1% and 0.05% of concentrations applied. |
