摘　　要：为了从天然植物中寻找新型、有效的植物源农药防治马蹄莲软腐病,测试了49种中草药的乙醇提取物对彩色马蹄莲软腐病菌(Erwinia carotovora subsp.Carotovora)的抑制作用及其MIC值和MBC值,并进一步进行盆栽防效试验。结果表明:五倍子乙醇提取物对彩色马蹄莲软腐病菌的抑菌作用显著,其次是丹参、乌梅、北五味子,其他中草药对彩色马蹄莲软腐病菌无抑制作用。五倍子提取物浓度为30 mg/mL时,盆栽防效达到65%。The ethanol extracts of 49 species Chinese herbal were tested for inhibiting the growth of pathogenic bacteria（Erwinia carotovora subsp. Carotovora） from Zantedeschia hybrida. The minimal inhibitory concentration and the minimum bactericidal concentration of some herbs which had significant inhibitory effects to pathogenic bacteria were detected, and pot control efficacy of which is the most significant inhibitory effects were conducted. The results showed that 4 species of Chinese herbs including Salvia miltiorrhiza, Schisandra chinensis, Galla chinensis and Prunus mume could effectively inhibit the growth of Erwinia carotovora subsp. Carotovora,and the other showed no inhibitory activity against the pathogenic bacterial. The control efficacy of Galla chinensis ethanol extracts with 30 mg/mL was 65%.
