6种杀菌剂对金线莲病害及生长的影响

摘要

以福建产金线莲Anoectochilus roxburghii为材料，研究不同杀菌剂对金线莲病害防治及生长指标动态的影响。结果表明，多菌灵和甲基托布津对金线莲病害的防治效果较好，相对防治效果达到55.3%和47.1%；而百菌清和叶枯唑对病害的相对防治效果虽只有26.9%和5.3%，但二者处理对金线莲的茎粗和叶面积的增长有明显的促进作用。精甲霜·锰锌和乙蒜素在病害防治及促进生长指标方面无突出表现。%Six germicides were chosen to study their effect on the diseases and growth index of artificial cultivated Anoectochilus roxburghii. The results showed that: Carbendazim and Thiophanate-methyl played a significant effect, their relative disease control rate reached 55.3%and 47.1%;Chlorothalonil and Bismerthiazol increased the stem diameter and leaf area of A. roxburghii effectively while their relative disease control rate just reached 26.9% and 5.3%. Metalaxyl-M mancozeb and Ethylicin had no outstanding performance in both disease prevention and control and growth index promoting.
