为解决烤烟调茬困难的现状,烟薯间作已发展成为临沂烟区一种行之有效的新型套种模式。烟薯不同间作类型对烤烟综合效应研究结果表明:2种烟薯间作模式大田生育期比烤烟单作缩短7 d左右;烟株株高、茎粗、有效叶数有优于烤烟单作的趋势;烟株病毒病发病率和病情指数比烤烟单作明显降低;单位面积总收入比烤烟单作增加,体现了较好的经济效益,为临沂烟区烟薯间作的推广提供理论支撑。
In order to solve the difficult situation of flue-cured tobacco stubble, intercropping has become a new intercropping model of Linyi tobacco growing area. The results of comprehensive effects of different intercropping types on flue-cured tobacco showed that the growth period of two intercropping modes of tobacco-straw intercropping system was shorter than that of flue-cured tobacco monoculture for about 7 d, and the height, stem diameter and effective leaf number of tobacco plants were superior to those of single flue-cured tobacco ; The incidence of disease and disease index of tobacco plant virus was significantly lower than that of tobacco single plant; the total income per unit area was higher than that of flue-cured tobacco, which reflected better economic benefits and provided theoretical support for the promotion of tobacco-potato intercropping in Linyi tobacco growing area.
