微生物菌剂防治茄子黄萎病田间药效试验

Field Efficiency Trials of Microbial Fertilizer Against Verticillium dahliae Kled.of Eggplant

以茄子黄萎病为研究对象,采用调查病情指数和病株率的方法,研究了微生物菌剂对茄子黄萎病的防治效果。结果表明:经过基质处理和后期灌根处理的小区,茄子黄萎病的病情指数和病株率最低,防治效果最佳。凡是经过基质处理的小区防治效果均高于仅仅灌根处理的小区。而且菌肥的浓度越高,防治效果越好,产量越高。因此该微生物菌剂具有广阔的应用前景。

Taking Verticillium dahliae Kled.as material,the effect of microbial fertilizer on controlling Verticillium dahliae Kled.of eggplant was researched.The results showed that the plot which was used substrate treatment and rootirrigation treatment later together,the disease index and the rate of diseased plant was the lowest,control efficiency was the best.And the control efficiency of all plots with substrate treatment was higher than just root-irrigation treatment.Further more the higher concentration the better effect,and the yield was higher.The result indicated that the microbial fertilizer had a broad application prospect.
