烟稻轮作的精细化气候区划研究

针对烤烟生产的关键气象因子,分析对比瑞金与国内外其他烟叶种植区的气象条件,建立了评价指标,运用GIS技术对瑞金市烟稻轮作进行了气候区划。结果表明,瑞金市光、热资源丰富,大部分地区适宜推广烟稻轮作的栽培模式;600～800m的一季稻区,适宜开展单季轮作,开展优质烟叶生产;在海拔高度350～600m的双季稻和一季稻共存区,可实行烟＋早中熟晚稻轮作制,开展优质烟叶生产;在海拔高度150～350m的双季稻区,可实行烟＋迟熟晚稻轮作制,但应注意防御高温低湿天气对烟叶造成的危害;150m以下或800m以上的地区不适宜推广烟稻轮作。

Climate Zoning and Analyzing of Tobacco-Rice Rotation in Ruijin

Aiming at the key meteorological factors of flue-cured tobacco production,the weather conditions of local and other domestic and international tobacco-growing areas were analyzed and compared to establish an evaluation index.Based on the weather stations' observation data of the daily temperature,precipitation and sunshine hours in and around Ruijin City from 1971 to 2000,GIS technology was used for Ruijin tobacco-rice rotation for the climate divisions.The results showed that Ruijin are rich in light and heat resources,most suitable for promotion of tobacco-rice rotation mode;At the altitude of 600-800 m the one season rice area,It is suitable using carry out single-season tobacco-rice rotation to carry out high-quality tobacco production;At an altitude of 350-600 m high double-crop rice and season rice area,it is suitable using carry out tobacco and early-late rice crop rotation system to carry out high-quality tobacco production;3.At the altitude between 150-350 meters the double rice cropping area,it can implement tobacco-late-maturing rice crop rotation system,but it should be noted to defense high-temperature low humidity weather harming tobacco growth;5.Below 150 meters or above 800 meters the areas are not suitable for promotion of tobacco-rice rotation.
