摘要：

田间试验表明,采用“一封一杀”的动态防治模式,以“封闭为主,茎叶喷雾为辅”的防治策略较为符合浙中稻区水稻直播田生产用药实际。“一封一杀”是指播后芽前每667 m2用30%丙草胺 EC100 mL进行土壤封闭,苗后杂草用300 g/L丙草胺EC100 mL+3%氯氟吡啶酯OD 53.3 mL、13%氰氟·氯氟吡啶酯EC 80 mL+100 g/L氰氟草酯EC100 mL、10%双环·双唑GG 200 g、39%敌稗·异噁草松EC 200 mL+85%丁草胺EC 47 mL喷施茎叶;或每667 m2用4%双唑草腈SC 150 mL进行土壤封闭、播后10~15 d上水撒施2%双唑草腈GR 600 g。

Abstract:

Field experiments showed that, adopting the management strategy of “one close and one kill” dynamic control mode, rely mainly on soil closuring while stem-leaf spraying is more in line with the actual production and application of pesticides in direct-seeded rice fields in the mid-Zhejiang rice area. “one close and one kill” means that 30% Preitochlor EC100 mL every 667 m2 is used for soil closuring after sowing before budding, and spraying the stems and leaves of the post-emergence weeds with 300g/L Pretilachlor EC100 mL+ 3% florpyrauxifen OD 53.3 mL, or 13% Cyhalofop-butyl and Florpyrauxifen mixture EC80 mL+ 100 g/L florpyrauxifen EC100 mL, or 10% Dicyclosulfone and Bisoxadionitrile GG 200 g, or 39% Propanil and Clomazone mixture EC 200 mL + 85% Butachlor EC47 mL, or 4% Bisoxadionitrile SC 150 mL is used for soil sealing, and spraying 2% Bisoxadionitrile GR 600 g 10~15d after sowing.
