温室电除雾防病促生机的除雾降湿效果

针对贵州省遵义地区烤烟漂浮育苗设施育苗过程中的高湿、低温和病害多等诸多问题，试验监测空间电场环境中漂浮育苗设施内空气水分含量、相对湿度的变化规律以及与对照的差异，并结合作物生长状况和生理代谢的变化，科学地阐述空间电场环境中空气含水量、相对湿度与设施保温、烟苗生长速度之间的关系。结果表明，温室电除雾防病促生机产生的空间电场具有强烈的除雾、降低空气含水量的作用，其降幅可达40%之多，并显著降低了卷帘通风次数，减小了温差波动幅度，保持了高于对照0.5～2 ℃的温度优势，成苗时间较对照缩短了5 d。 

Demisting and Humidity Reducing Effect about Greenhouse Electric Defogging Health Promotion and Disease Prevention System

Aimed at high humidity，low temperature，and many other problems during process of cultivation of flue-cured tobacco floating seedling system in Zunyi region of Guizhou province，moisture content，changing rule of relative humidity in floating seedling establishment in space electric field and differences between control groups were monitored.Combined with change of crop growth and physiological metabolism，relationship between air moisture content，relative humidity and facility heat preservation and growth rate of tobacco seedling in space electric field environment were scientifically analyzed.Results showed that spatial electric field produced by greenhouse electric defogging health promotion and disease prevention system had a strong effect on defogging and reducing air moisture content.Decrease number was more than 40%，number of shutter ventilation was significantly reduced，difference in temperature swings was reduced，0.5～2 ℃ temperature advantage was kept，and seedling time was shortened by 5 d.
