[目的]探讨三色源菌剂在烤烟上的应用效果。[方法]以云烟97为材料,以三色源菌剂进行处理的烟田与常规烟田进行对比,考察2种烟田的烟叶农艺性状及外观质量。[结果]试验表明,施用三色源菌剂能促进烤烟生长发育,平均株高比对照提高9.16 cm,平均有效叶数较对照多1.33片;对烟叶外观质量、化学成分协调性有积极作用;有利于提高烤烟综合经济性状,产值较对照高5 574.9元/hm2。[结论]研究可为三色源菌剂的推广应用提供科学依据。
[Objective] The research aimed to discuss the application effect of trichromatic germicides on flue-cured tobacco. [Method] With Yunyan 97 as material, the tobacco fields treated with trichromatic agents were compared with those of conventional tobacco fields, and the agronomic characters and appearance quality of the two kinds of tobacco fields were investigated. [Result] The experiment showed that the application of trichromatic germicide could promote the growth and development of flue - cured tobacco. The average plant height was 9.16 cm higher than that of the control and the average effective leaf number was 1.33 more than that of the control. It had a positive effect on the appearance quality and chemical composition coordination of tobacco leaves. This will help to improve the comprehensive economic traits of flue-cured tobacco with an output value of 5 574.9 yuan / hm2 higher than that of the control. [Conclusion] The study could provide a scientific basis for the popularization and application of tricolor sources.
