利用重庆市万州区近30年(1981—2010年)历年整编资料及20世纪80年代初期山地立体气候考察资料,应用气候统计分析方法,分析了烤烟种植所需的光、温、水三大气候生态条件和不利气象因素,同时基于GIS技术制作出精细的烤烟气候生态适应性区划图。结果表明:烤烟生产对气象条件的要求非常严格,其产量特别是品质与气象条件关系十分密切。烤烟烟叶成长期平均气温20~25℃,田间持水量70%~80%,阳光充足并时遮时晒的气候生态环境对烤烟优质生产最有利。海拔高度700~1500m范围都是烤烟生产的适宜栽培区,而海拔高度900~1300m地带则是发展烤烟生产的最适生态环境。
Based on the reorganized data from the past 30 years (from 1981 to 2010) of Wanzhou District of Chongqing Municipality and the investigation data of mountainous three-dimensional climate in the early 1980s, this paper analyzes the three climatic ecologies of light, temperature and water needed by planting tobacco with the method of climatic statistic analysis Conditions and unfavorable meteorological factors, and at the same time, a fine flue-cured tobacco ecological adaptability zoning map is produced based on the GIS technology. The results showed that the requirements of flue-cured tobacco production on the meteorological conditions are very strict. The output, especially the quality and the meteorological conditions, are closely related. Flue-cured tobacco growing season average temperature of 20 ~ 25 ℃, field water capacity of 70% to 80%, adequate sunshine and cover the sun when the climate and ecology of flue-cured tobacco production of the most favorable quality. The range of 700 ~ 1500m above sea level is suitable for cultivation of flue-cured tobacco, while the 900 ~ 1300m above sea level is the most suitable ecological environment for the development of tobacco production.
