- 摘要:
- 大豆根腐病是导致大豆减产的重要因素之一,不但危害重而且防治困难,而尖孢镰刀菌是黑龙江省大豆根腐病的优势菌种,为研究大豆尖孢镰刀菌根腐病的生物防治情况,采用蛇床子和知母的提取物对大豆尖孢镰刀菌进行抑菌试验。结果表明:蛇床子和知母的提取物对大豆尖孢镰刀菌都有抑制作用,蛇床子提取物在浓度为20%时抑菌效果最好,抑菌率为90.36%,而当知母提取物浓度为40%时,抑菌率为65.27%。
- Abstract:
- Soybean root rot is one of the important factors leading to soybean yield reduction.It is not only harmful but also difficult to control.Fusarium oxysporum is the dominant strain of soybean root rot in Heilongjiang Province.In order to study the biological control of soybean Fusarium oxysporum,the extracts of Cnidium monnieri and Anemarrhena asphodeloides were used in this experiment.The results showed that the extracts of Cnidium monnieri and Anemarrhena asphodeloides had inhibitory effects on Fusarium oxysporum.The antimicrobial effect of the extracts of Cnidium monnieri was the best when the concentration was 20%.The antimicrobial rate was 90.36%.When the concentration of the extracts of Anemarrhena asphodeloides was 40%,the antimicrobial rate was 65.27%.
