- 摘要:
- 为比较Cu2O纳米粉与Cu2O超细粉对番茄早疫病菌的抑菌效果,以番茄早疫病菌菌种为试材,用原粉体和配制的粉体悬浮液对番茄早疫病菌进行抑菌试验,采用含药培养基法进行毒力测定。结果表明:Cu2O纳米粉与Cu2O超细粉对番茄早疫病菌有非常明显的抑制作用,抑菌效果与含药培养基中粉体的质量浓度呈正相关,Cu2O纳米粉悬浮液和Cu2O超细粉悬浮液对番茄早疫病菌的抑菌效果明显优于Cu2O纳米粉与Cu2O超细粉;Cu2O对番茄早疫病菌的抑制作用取决于粉体中微粒的含量以及微粒在介质中的分散稳定性。
- Abstract:
- In order to compare the effect of Cu2O Nanoparticles and Cu2O ultrafine powder on Alternaria solani.The bacteria-inhabiting experiment to the early blight fungus with both original powder and powder suspension by adopting the drug-containing medium was condacted to test toxicity.The results showed that the inhibitory activities of Cu2O nanoparticles and Cu2O ultrafine powder to early blight fungus of tomatoes were very striking and proved a positive correlation between the degree and mass concentration of the powder in the drug-containing medium.The inhibitory activities of nanoparticles and Cu2O ultrafine powder suspension was superior to that of Cu2O powder and Cu2O ultrafine powder.The inhibitory activities of Cu2O to tomatoes depended on the particle content in the powder and the disperse stability of the powder in the medium.
