南平市烤烟生产气象条件分析与气象服务

Analysis of meteorological conditions and services for tobacco production in Nanping

分析了南平市主要气象条件和冰雹、大风灾害,以及1996-2005年温度、降水量、日照时数对单位产量、上等烟比率的影响。结果表明,南平市热量条件较好,特别是季节温度变化与烤烟生长所需温度相一致;但光照略显不足;成熟期降雨量偏多、相对湿度偏大对烤烟成熟和采烤不利;冰雹、大风灾害影响明显。另,单位产量与平均气温、日照时数呈正相关,与降水量呈负相关。同时,实践表明,针对烤烟生产开展的种植气候区划、移栽期气象预报、人工防雹等气象服务和体系建设,达到了趋利避害的目的,具有现实指导意义。

Based on analysis of major meteorological conditions such as hail,wind damage,1996-2005 temperature,precipitation,sunlight hours and their influence on tobacco yield,its percentage of high quality in Nanping,it is held that besides the favorable temperature and water conditions the seasonal variation of temperature satisfies the need of tobacco growth.But insufficient illumination and high relative humidity caused by large precipitation in mature period are unfavorable for mature,harvest and fluecured.Meanwhile there are hails and strong-wind disasters. Yield per unit is positively correlated with average temperature and sunlight hours, but negatively correlated with precipitation. In addition, the meteorological services and system construction such as growing climate zoning, weather forecast in transplanting period, and hail prevention are significant for giving full play to advantages and preventing from harms.
