烟草作为重要的经济作物,前人已经进行了大量的研究工作。本次工作在前人的基础上,建立了烟草的质量评价体系并将烟草评价体系中评价指标与元素指标建立了联系。运用地球化学方法分析了烟叶的主要构成元素、烟叶对元素的富集、元素对品质的影响,结合土壤中元素的分布特征,推断出优质烟草产区分布,以达到地球化学为农业规划服务的目的。
As an important cash crop, tobacco has carried out a great deal of research work. Based on the previous work, this work established the tobacco quality evaluation system and established the evaluation index and the element index in the tobacco evaluation system. Using geochemical methods to analyze the main components of tobacco leaves, the enrichment of elements in tobacco leaves, the quality of elements and the distribution characteristics of elements in the soil, the distribution of high quality tobacco producing areas is deduced to achieve the effect of geochemistry on agricultural planning purpose.
