Production Technology Research Of Features High Quality Tobacco Of Red Sky Red River Group Based On The Species And The Ecological Diversity

To meet cigarette brand’s raw material need of the Hongyunhonghe Tobacco(Group) CO.,Lid, the differentiation of tobacco production from two aspects of variety and ecological environment are studied. Through researching,it has been clear about the main variety, leaf production bases and production techniques of raw material differentiation strategy.The results are as follows as:1According to the evaluation of existing various tobacco varieties, we choosed Hongda,K326as "reservation varieties"and main varieties of the raw material differentiation strategy,and stabily continued growing, gradually reduced planting of Yunyan87,and stopped planting of Yunyan85.2In new varieties from USA, through comparing field performance, disease resistance, economic characters, appearance quality and internal quality, in the light of performance of comprehensive agricultural and industrial characters,we eventually also selected NC102and NC297as main varieties of raw material differentiation strategy.3After test, the ecological condition of raw material base was optimizded, the altitude optimized1342～2000m, the average temperature of5～8month optimnized19.2～22.0℃, the average rainfall of5～8month optimized636～792mm, the average sunshine hours of5～8month optimized517～727h.4In the assembly integrated the original features high quality tobacco production technology, based on the characteristics of the high quality tobacco production, with the industrial characteristic of high quality tobacco’s demand as the guide, make the red sky red river group features high quality tobacco cultivation technology supporting scheme.
