大花蕙兰软腐病防治药剂及防治适期的研究

Study on Chemical Control and Optimum Control Period to Soft Rot of Cymbidium

为了寻找一种针对大花蕙兰软腐病的高效环保新药剂,采用灌根和喷雾的方法对大花蕙兰软腐病的防治进行药剂的筛选试验,同时还进行了防治适期的研究。研究的结果显示:新霉素的防治效果要优于其他的防治药剂,换盆前进行灌根的防治效果最好,10天的防治效果为92.1%,20天的防治效果为88.6%,30天的防治效果为87.1%,与其他处理对比差异极显著,显示了新霉素在农业上的良好应用前景,为把新霉素开发成一种新型农用抗生素提供了试验参考。

In order to find a new potion and efficient environmental protection against soft rot of Cymbidium, pharmaceutical screening test method to adopt irrigating and spray of Cymbidium soft rot, also conducted a study of the control period. The study results showed： neomycin prevention was better than the other control chemicals. The best control effect before irrigating change a basin. The prevention effect of 10 d and 20 d control effect of 92.1% and 88.6%, the 30 d control effect of 87.1%. Significant differences with other processing compared, Showing neomycin good application prospects in the agriculture, laid a certain foundation developed into a new type of agricultural antibiotic neomycin.
