摘 要:分析湖北兴山烟区土壤养分及所产烟叶的质量状况,结果表明:(1)该烟区土壤有机质含量丰富,氮、磷含量适中,钾含量能够满足烟叶生长需求,大多中微量元素含量丰富,但土壤水溶性氯含量偏低,建议适当施用含氯肥料。土壤养分含量存在较大的变异,尤其以磷素的变异最大;(2)兴山烟区不同土壤类型中以石灰土和黄棕壤的土壤养分状况更适宜于优质烟叶的生长;(3)兴山烟区烟叶的物理性状优良,外观品质佳;烟叶化学成分含量较适宜,但上、中部叶的烟碱含量较高;烟叶香气质和感官质量较好。Status of soil nutrients and quality of tobacco leaves in Xingshan,Hubei Province were analyzed.The results indicated that:(1)The content of organic matter was rich;total N,hydrolytic N,total P and available P were reasonable;total K and available K could meet the needs of the growth of flue-cured tobacco;the contents of most medium-micro elements were rich.But the content of water soluble Cl^- was rather low,and addition of suitable amount of Cl^- fertilizer was suggested.The contents of soil nutrients showed a big variation among locations,and had the biggest variation coefficient for P element.(2)Status of soil nutrients of calcareousness and yellowish-blown was more suitable for the growth of high quality flue-cured tobacco among different soil types in Xingshan tobaccogrowing areas.(3)Xingshan tobacco leaves had good physical characters,high appearance quality and reasonable chemical components,but the content of nicotine was high in both upper and middle leaves.Xingshan tobacco leaves had rich aroma quality and good sensory evaluation.
