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、茵毒净、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、茵毒净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、茵毒净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 effervescent tablets (6.5% chlorine dioxide), were tested through spray and immersion, respectively. The results showed that the relative control effect of 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, Yubao at a dilution of 100 reached 100%.
