摘 要:为合理评价杀虫剂及烟草生态安全性提供理论参考依据,以烟草生产中常用的4种杀虫剂处理烟草幼苗,并对其叶绿素含量进行了测定。结果表明,阿维菌素、吡虫啉和啶虫脒导致烟草幼苗叶绿素a、叶绿素b、叶绿素总量和类胡萝卜素含量上升,叶绿素a/b下降;甲维盐则导致烟草幼苗叶绿素a、叶绿素b、叶绿素总量和类胡萝卜素含量下降,叶绿素a/b上升。从叶绿素含量的变化来看,阿维菌素、吡虫啉和啶虫脒对烟草幼苗相对是安全的,而甲维盐则会对其造成不利的影响。In order to evaluate the ecological risk of insecticides to the tobacco (Nicotiana tabacum L.), the contents of chlorophyll and carotenoid in tobacco seedling leaves treated with the four insecticides were measured. When the tobacco seedlings at nine-leave stage which were raised under greenhouse condition, the contents of chlorophyll and carotenoid of the ninth leave were tested after treated with 100μl of the four insecticides. The result showed that the contents of chlorophyll a, chlorophyll b, the total chlorophyll and carotenoid of the tobacco seedling leaves treated with avermectins, imidacloprid and acetamiprid increased, the ratios of Chla / Chlb decreased. The contents of chlorophyll a, chlorophyll b, the total chlorophyll and carotenoid of the tobacco seedling leaves treated with emamectin benzoate decreased, the ratios of Chla/Chlb increased. Therefore, avermectins, imidacloprid and acetamiprid insecticides are safe to the tobacco, and emamectin benzoate can cause adverse effects.
