摘　　要：为了探索不同促根剂配方对烤烟的影响,在利川开展烤烟不同促根剂配方对烤烟生长发育和产质量影响的研究。结果表明,从烤烟农艺性状、根系指标、经济性状和化学成分方面,CG1处理(0.1%细胞分裂素+0.5%磷酸二氢钾)促根剂和CG4处理(可溶性黄腐酸钾对水500倍)促根剂均可以促进烟株根系发育,提高产量和产值,提升烟叶品质,是适宜湖北烟区的烤烟促根剂配方。In order to research the effects of different root promoters on flue-cured tobacco,we carried out the experiments on different root promoters on growth,yield and quality of flue-cured tobaccos in Lichuan.Results showed that as for agronomic characters,root index,economic characters and chemical composition of flue-cured tobacco,the treatments of CG1(0.1%cytokinin+0.5%potassium dihydrogen phosphate)and CG4(soluble potassium fulvate added 500 times to water)could promote the root development of tobacco plants,increase the yield and output value,and improve the quality of tobacco leaves,which was suitable root promoters for Hubei tobacco areas.
