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 inhibition of Fulvia fulva (Cooke) Cifferri against Fulvia fulva fulvum was studied under different concentrations of bamboo vinegar, silica, sodium silicate and bamboo vinegar in vitro and in vitro. Within the range of experimental dilution, the disease index decreased with the increase of bamboo vinegar liquid silicon concentration, and the control effect on tomato leaf mold increased. In the same treatment, the control effect of bamboo vinegar composite silicon on tomato leaf mold was significantly higher than that of sodium silicate and bamboo vinegar. When the bamboo vinegar liquid silicon concentration of 2 mmol / L, the inhibitory rate of mycelial growth of tomato leaf mold was 46.57%, the control effect on tomato leaf mold was 53.45%.
