为了探索适合寒地水稻旱育秧田的新型封闭除草剂品种，进行了寒地水稻旱育秧田杂草防除效果和水稻安全性研究。结果表明：30％恶嗪草酮悬浮剂180～450 mL?hm‐2对寒地水稻旱育秧田禾本科杂草的防效较好，药后25 d株防效均在90％以上；但当使用剂量在300 mL?hm‐2以上时，水稻生长出现不良现象，从防除效果和水稻的安全性两方面考虑，建议30％恶嗪草酮悬浮剂在水稻旱育秧田播种覆土后使用低剂量12 mL?hm‐2为宜。

In order to explore new closed herbicides which suitable for cold rice-nursery ,the control effect on weeds and safety on rice of dry rice-nursery in cold area were studied .The results showed that :the control effect of 30% Oxaziclomefone SC for gramineous weeds was better when the concentration was between 180 and 450 mL?hm‐2 ,the control effect was more than 90% after 25 days ,but it was unhealthy for rice when the concentration was up to 300 mL?hm‐2 .Considered the control effect and safety of rice ,it is advisable to use the low dose-180 mL?hm‐2 for 30% Oxaziclomefone SC of dry rice-nursery in cold area .
