摘　　要：在室内采用浸种和幼苗茎叶喷雾处理的方法,测定了3种常用杀菌剂多菌灵、丙环唑和嘧菌酯对子莲植株的安全性。试验结果表明,在供试的浓度范围内,以50%多菌灵可湿性粉剂对子莲的安全性较高;25%丙环唑乳油较高浓度对子莲的生长具有明显的抑制作用;25%嘧菌酯悬浮剂则对子莲的幼嫩叶片较易产生药害。In the paper, we dipped lotus seeds in three different common fungicides with different concentrations respectively and sprayed the same fungicide on stem and leaves at seedling stage, to evaluate the safety of the three fungicides to seed lotus. The results showed that, 50% carbendazim wettable powder was safer to seed lotus, and 25% propiconazole emulsifiable concentrate in high concentration inhibited the growth of seed lotus obviously, while 25% azoxystrobin suspension concentrate was easier to produce injury to young leaves of seed lotus.
