摘要
HY—电热硫磺熏蒸器是采用电炉控温均衡发热方式,通过加热使硫磺升华形成微小的硫磺颗粒,均匀分布于相对密封的温室大棚内,抑制大棚内空气中及月季表面白粉病菌的生长发育。试验结果表明,在室温19～26℃范围内,硫磺蒸发量达5～10g/h,室温在30℃时硫磺蒸发量可达12g/h。它能在短时间(约3～4h)内使硫磺达到白粉病菌致死浓度,从而有效地治疗和预防月季白粉病。
A HY-Sulfurator was prepared by a stove controlling temperature and heating to produce many small sulfur particles which were well distributed in greenhouse as a result controlling powdery mildew of Chinese rose. Field experiments showed that the rate of sulfur fumigation was 5~10g/h when the temperature was from 19℃ to 26℃, while it was 12g/h when the temperature was 30℃ in greenhouse. Sulfur fumigation could reach the concentration of killing powdery mildew off within 3~4 h.
