摘要
采用6%抗坏血酸水剂对影响烟叶面积、烟叶干重、上等烟比例及烟草花叶病病情指数等各项指标的变化进行试验。结果表明:6%抗坏血酸水剂被烟草叶、茎吸收后,可调节生理机能,促进其生长发育,增强机体抗逆性和提高免疫能力,能使烟叶面积较对照平均提高14.0%、烟叶干重提高4.2%、上等烟叶比例提高2.7%,对烟草花叶病的平均防效高达90.7%,有利于优质烟叶生产,可在生产上大面积推广应用。
6 % ascorbic acid WA was used in tobacco to study the effects on leaf area, leaf dry weight, ratio of high-rate leaf and disease index of TMV. The results showed that 6 % ascorbic acid WA could promote tobacco growth and development and improve its adverse resistance and immunity, and the leaf area, leaf dry weight and ratio of high-rate leaf increased by 14.0 %, 4.2% and 2.7% compared with CK respectively, and the rate of controlling TMV was up to 90.7%, which indicates that 6 0% ascorbic acid WA can be popularized in tobacco production on a large scale.
