摘要
Abstract
Based on topographical, climatic, and other conditions in Zunyi, gradient, sunlight, temperature, and sunshine duration were used as parameters to classify the tobacco ecotypic areas in Zunyi. Cluster analysis result indicated that Zunyi tobacco region with 10 tobacco planting counties could be divided into two ecotypic aeras by Dalou Mountain as a boundary. The northern mountainous tobacco area contained Tongzi, Zhengan, Daozhen, Wuchuan, Renhuai and Suiyang county;while the southern highland tobacco area included Zunyi, Meitan, Fenggang, and Yuqing county. Northern mountainous tobacco area lie on the north of Dalou mountain, largely middle mountains and canyons with much terraced land and mesa, altitude is between 900-1 500 m, average sunshine duration per year is 1 050-1 150 h, average temperature per year is 14-16℃, average rainfall per year is 1 050-1 200 mm. Southern highland tobacco area lie on the south of Dalou mountain, landform is hill, valley, and basins, altitude is between 800-1 000 m, average sunshine duration per year is 1 000-1 200 h, average temperature per year is 15-16.5℃, average rainfall per year is 1 050-1 300 mm. Tobacco leaf in Zunyi has two styles, middle-scent is primary and faint-scent is secondary. Southern highland tobacco area belong to the former and northern mountainous tobacco area belong to the latter.关键词
