唐菖蒲重茬病害的化学防治试验

Chemical control of continuous cropping disease on gladiolus hybrid

试验选用三种药剂 ,三种浓度在生长期间进行三次灌根处理 ,防治唐菖蒲重茬病害。结果表明 ,花朵数、子球球径、叶片干尖程度、叶色均明显好于对照。其中 ,用 5 0 %多菌灵 6 0 0倍液处理 ,病害的防治效果和生物学性状的表现最好。

The experiment chose 3 medicaments and 3 concentrations by 3 times of irrigating roots to control Gladiolus continuous cropping disease.The result showed that florets,daughter corm size,leaf color etc exceeded the comperison,dry peak of leaf was less than the comperison.It showed the best controlling effect and the best biological characters after irrigating root by using 600 times of 50% carbendazim.
