摘　　要：选取前期从烟草根际筛选获得的烟草亲和性解钾菌TK35菌株,通过盆栽试验和田间试验,评估该菌株对烟草生长、钾素吸收及烟叶产质量的影响。盆栽试验结果表明,与未施菌的烟株相比,施加TK35菌液烟株的叶片鲜重、叶片干重、叶片钾含量及根际土壤速效钾含量分别提高13.89%、11.97%、11.46%和4.92%。田间试验结果表明,施TK35菌液、80%用量钾肥处理效果最佳,与不施菌液、施全肥对照(CK2)相比,其中部叶钾含量和上部叶钾含量分别提高14.64%和35.97%,中部烟叶比例、上等烟比例、产量和产值分别提高8.33%、3.20%、3.83%和5.35%。解钾菌TK35可提高烟草根际土壤速效钾含量,提高烟叶钾含量,促进烟株生长,有效提高烟叶产质量,提高烟草经济效益,具有开发应用潜力。A tobacco-affinity potassium-solubilizing bacterial strain TK35,obtained from tobacco rhizosphere in the early research,was applied to estimate its effects on growth,potassium uptake,yield and quality of tobacco leaves through pot and field experiments.The results of the pot experiment showed that,compared with the control without bacteria application,the fresh weight,dry weight,potassium content of leaves and available potassium content in the rhizosphere soil of tobacco plants treated with TK35 bacterial liquid increased by 13.89%,11.97%,11.46%and 4.92%,respectively.The results of the field experiment showed that the application of TK35 and 80%potash fertilizer treatment had the best effects.Compared with the treatment without bacterial solution and applying total fertilizer(CK2),the potassium content of middle leaves and upper leaves under this treatment increased by 14.64%and 35.97%,and the proportion of middle tobacco leaves,the proportion of superior tobacco leaves,yield and output value under this treatment increased by 8.33%,3.20%,3.83%and 5.35%,respectively.Potassium-solubilizing bacterium TK35 could increase the available potassium content of tobacco rhizosphere soil,improve the potassium content of tobacco leaves,promote the growth of tobacco plants,effectively enhance the yield and quality of tobacco leaves,and increase the economic value of tobacco.Strain TK35 had the potential for development and application.
