摘　　要：为了筛选烟草漂浮育苗盘消毒药剂,采用喷雾和浸泡2种方法比较了绿先锋、育宝、菌毒净、华星二氧化氯(泡腾片)等4种药剂对接种TMV(烟草花叶病毒)漂浮盘的消毒效果。结果表明:对漂浮盘喷雾消毒,以绿先锋200倍和300倍、华星二氧化氯200倍、菌毒净200倍、育宝80倍液效果最好,防效均达到了100%;华星二氧化氯300倍和500倍液消毒效果较差。对漂浮盘浸泡消毒,以绿先锋300倍和500倍、育宝100倍、菌毒净200倍、华星二氧化氯200倍液效果最好,防效均达到了100%。In order to select effective disinfectants for floating tray against TMV in tobacco floating seedbed system, four disinfectants, including Lvxianfeng （16% chlorine dioxide）, Yubao （40 % N-hydroxyethyl-methylamine） ,Jundujing （5 %sodium dichlorisocyanurate）, Huaxing effer- vescent tablets （6.5% chlorine dioxide） ,were tested The results showed that the relative control effect of through spray and immersion, respectively. spraying Lvxianfeng at a dilution of 200 or 300,Jundujing at a dilution of 200, Huaxing effervescent tablets at a dilution of 200, Yubao at a dilution of 80 on floating tray were best, followed by Huaxing effervescent tablets at a dilution of 300 and 500. The disinfection effect via immersion in Lvxianfeng at a dilution of 300 or 500,Jun- dujing at a dilution of 200, Huaxing effervescent tablets at a dilution of 200 or 400,Yuhao at a dilution of 100 reached 100 %.
