摘要
研究了硫酰氟熏蒸对片烟质量的影响,并测定了硫酰氟熏蒸后片烟中氟的残留量。结果表明:硫酰氟的使用剂量为20 g/m3,熏蒸120 h,即CT(浓度与时间的乘积)值为2400时,烟草甲成虫、幼虫、蛹及卵全部死亡;硫酰氟处理对片烟常规化学成分影响不明显,总植物碱稍有下降;硫酰氟对片烟的质量无不良的影响;硫酰氟熏蒸后,片烟中氟的残留量增加幅度为3.1 mg/kg。
The fumigation of tobacco strips with sulfuryl fluoride and its influence on strips＇ quality were studied, and the residue of fluorine in strips was also detected. The results showed that ： 1 ） at sulfuryl fluoride concentration of 20 g/m^3 and fumigation time of 120 hours, namely at a CT value （product of concentration and time） of 2400, the adults, larvas, pupas and eggs of Lasioderma serricorne were all killed; 2 ） the influence of sulfuryl fluoride treatment on routine chemical components in strips was not obvious, total alkaloid content declined slightly; 3 ） sulfuryl fluoride had no negative effect on strips＇ quality; 4） the residue of fluorine in strips increased by 3.1 mg/kg after fumigation.
