竹醋液用于土壤百合疫霉菌灭杀试验研究

Experimental Study on the Lily Phytophthora Antimicrobial Functions of Bamboo Vinegar Used in Soil

[目的]验证竹醋液对百合疫霉菌灭杀试验抑菌效果及土壤消毒药效。[方法]采取不同用量竹醋液、25%多菌灵可湿性粉剂及空白试验来进行对比试验。[结果]结果表明,竹醋液对百合疫霉菌有较强的抑制作用,竹醋液对百合疫霉菌菌丝生长的有效抑制中浓度为6 g/L。出苗后第1次施药前调查,竹醋液15 000、30 000 ml/hm2用量比25%多菌灵可湿性粉用量6 000 g/hm2效果好,竹醋液30 000ml/hm2用量平均病株率达5.2%(5.4%);空白对照组的平均病株率为42.4%(67%),竹醋液土壤杀菌消毒药效明显。[结论]竹醋液是一种环保的植物杀菌剂,能较好地满足土壤消毒剂的需求,价廉易得,是一种值得推广的杀菌剂。

Objective The aim was to verify the bamboo vinegar on the lily phytophthora antimicrobial functions and soil disinfection efficacy. [Method] The compare experiment with the different dosage of bamboo vinegar liquid,25%carbendazim wet powder,and the blank test had been proceed. [Result] The re-sults showed that the bamboo vinegar had strong antibacterial activity to lily phy-tophthora.The mycelial growth active inhibition concentration was 6 g/L. The field pesticide effect of bamboo vinegar liquid 30 000 ml/hm2 was better than the bamboo vinegar liquid 15 000 ml/hm 2, 25% carbendazim wet powder after the first drug delivery survey, the average rate of the diseased plant was 5.2%（5.4%）and the blank control group was 42.4%（67%）.It had obvious soil steriliza-tion efficacy. [Conclusion] The bamboo vinegar fluid was a kind of green plant fungicide,could meet the needs of soil disinfectant and worth promoting.
