禄丰基地烤烟生态环境和烟叶质量分析

利用云南省楚雄州江苏中烟禄丰烤烟生产基地的气候观测数据、土壤理化分析结果,分析了当地烤烟种植的气候适生性、气候相似性和土壤适宜性,通过分析禄丰基地烟叶外观质量、化学成分与感官质量,对烟叶质量作了综合评价。结果表明:(1)禄丰基地气候适生性指数(Climate Feasibility Index,CFI)为100%,为烟叶最适宜种植区;与国内烟区的气候相似性距离分布在0.50～0.99,与国外烟区的气候相似性距离分布在0.75～0.88,都达到高级相似。(2)禄丰基地的土壤适宜性指数(SFI)为0.73,达到2级水平,接近1级,土壤适宜于种植烤烟。(3)禄丰基地烟叶香型指数(K值)为0.26,为典型的清香型烟叶;烟叶成熟度好,叶片结构疏松,香气质较好,杂气和刺激性相对较小。

Evaluation of Ecological Environment and Flue- cured Tobacco Quality in Tobacco- growing Areas of Lufeng Base

Based on the meteorological data and physicoehemical properties of soil in Lufeng base of China tobacco Jiangsu industrial Co. ,Ltd. , climate feasibility, climate similarity and soil feasibility were analyzed. By analyzing tobacco appearance, chemical components and sensory, comprehensive quality of tobacco leaves were evaluated. The resuits were as follows： （ 1 ） climate feasibility index（CFI） of Lufeng base was 100%. Lufeng base was the most suitable planting area of tobacco. The similarity of the climatic conditions of flue-tobacco for other tobacco-growing areas reached the higher degree. The value of similarity ranged from 0. 50 to 0. 99. （2） Soil feasibility index of Lufeng base was 0. 73. SFI reached 2 class levels, close to 1 class levels, which suggested soil of the region was suitable for planting flue-cured tobacco. （ 3 ） By analyzing meteorological data of Lufeng base, tobacco flavor index （ K value） was 0. 26. Tobacco leaves were typical of clear scent. Tobacco leaf structure osteoporosis maturity were better. Quality of aroma was high, undesirable taste and biting taste were small.
