恩施州不同类型烟区气候特征及其适宜性分析

Analysis of Climatic Characteristics and Suitability in Different Tobacco-growing Areas in Enshi

摘要: 依据气候数据,通过聚类分析,将恩施州8个植烟县（市）分为3个区域类型：利川、咸丰为一类,巴东单独为一类,宣恩、鹤峰、来凤、建始和恩施为一类；3类区域各气候因子之间具有显著差异。与国内外优质烟区气候特征比较,利川、咸丰与美国相似,但该类型区域所产烟叶化学成分含量与美国烟区相比有较大差异。3类区域烟叶化学成分含量之间均具有显著差异。气候条件对烟叶内在品质有较大的影响。

Abstract: The climatic data of eight tobacco planting areas in Enshi were classified to three types by means of clustering analysis. The first type was Lichuan and Xianfeng, the second type was Badong, and the rest areas was the third type. The climatic among the three types had significant differences, and compared to foreign tobacco-growing areas, the Lichuan and Xianfeng were similar to USA,but the chemical components of tobacco were different. The tobacco chemical components among the three types had significant differences, the climatic factors had great influence on tobacco quality.
