摘要 针对遵义地区烤烟漂浮育苗阶段棚室环境和病害发生特点,在漂浮育苗棚内设置了由电除雾防病促生机建立的空间电场防病系统,并对根茎病害、气传病害、烟草病毒病和气候斑点症进行了调查。结果表明,空间电场环境中根茎病害的发生率明显低于对照,气传病害的发生率低于对照,空间电场不会造成烟草气候斑点症的发生;试验组烟草病毒病的发生程度低于对照组,但不能明确归于空间电场的作用,应是综合防治的结果。调查结果证明,空间电场防病技术可以用于烤烟漂浮育苗棚根茎病害、气传病害的预防,烤烟病毒病应采用物理植保综合措施来预防。 According to the features of disease and environment in flue-cured tobacco floating seedling stage of Zunyi region, spatial electric field preventing disease system which built by biological effect electrostatic field generator was set in floating seedling shed. Root disease, air borne disease, tobacco virus disease and climate spot disease were investigated. Results showed that occurring rate of root disease was significantly lower than control group in spatial electric field environment, occurring rate of air borne disease was also lower than control group, and spatial electric field didn't lead to tobacco climate spot disease. Investi- gation results also showed that occurrence degree of tobacco virus disease in experimental group was lower than that in control group, but it could not be clearly attributed to the role of space electric field, it should be the result of comprehensive prevention and control. Investigation results proved that spatial electric field preventing disease technology could be used for the prevention of root diseases and air borne diseases in flue-cured tobacco floating seedling shed. Comprehensive physical protection measures should be adopted to prevent tobacco virus disease.
