不同除草剂在水稻免耕田的药效试验初探

A Preliminary Exploration On the Effect of Different Herbicides on Cultivation-Free Paddy

通过试验表明 :在水稻免耕上使用草甘膦、克无踪、百草枯、农民乐四种不同除草剂 ,对绝大部分杂草有较好的防除效果 ,但对狗牙根、雀稗、铁线草等恶性杂草普遍防除效果较差。

s The experimental result indicated that the application of the different herbicides like Glyphosate, Kewuzong, Paraguat and Nongminle into cultivation-free paddy had better effect on the prevention and control of the majority of weeds, but had worse effect on the virulent weeds like Para, Chlorosis and Delapon etc. At the same time, the methods and duration of the application of the different herbicides were also explored.
