摘要
研究了不同浓度竹醋液复合硅、硅酸钠溶液、竹醋液在室内离体条件和盆栽条件下对番茄叶霉病菌[Fulviafulva(Cooke)Cifferri]的抑制作用。在试验稀释范围内,随着竹醋液复合硅浓度增加,病情指数降低,对番茄叶霉病的防治效果增加。在相同处理中,竹醋液复合硅对番茄叶霉病防治效果要明显高于硅酸钠、竹醋液处理。当竹醋液复合硅浓度为2 mmol/L时,对番茄叶霉菌菌丝生长抑制率达46.57%,对番茄叶霉病的防治效果达53.45%。
The controlling efficiency of bamboo vinegar reunited silicon,sodium silicate solution and the bamboo vinegar at different concentration on leaf mold of tomato on the condition of indoor isolated leaf culture and pot culture were studied.The results showed that the disease index was getting lower and controlling efficiency against Fulvia fulva（Cooke） Cifferri increased with the increment of bamboo vinegar reunited silicon concentrations.In the same treat,control efficiency of bamboo vinegar reunited silicon was significantly stronger than those of the sodium silicate solution and the bamboo vinegar.And controlling efficiency was up to 53.45% with the inhibition ratio of 46.57% on fascicle growth at the concentration of 2 mmol/L.
