摘要
分析了2013年南平烟区烤烟生产过程的降雨量、气温、日照时数3个主要气候因子。结果表明,苗期日照时数偏少和寒潮影响不利于培育壮苗;旺长期个别时段降水少、气温低、日照少,不利返苗和烟株早生快发,影响烟株光合作用,对产量和品质形成不利影响,5月中下旬高温高湿造成病虫害发生流行;成熟采收期气象干旱,造成上部叶烟碱过高,对烟叶品质形成不利影响。寒潮、强对流和暴雨洪涝等气象灾害对烟叶生产造成一定损失。南平烟区通过烟苗移栽期预报、烤烟产量预报和人工防雹等气象服务,取得了显著效果。
The impact of three major climatic factors, rainfall, temperature and sunshine hours, on the production of flue-cured to- bacco in Nanping, 2013 was analyzed. The results indicated that at the seeding stage, less sunshine hours and cold waves were not conducive to seedling cultivation. In the vigorous growing period, less precipitation, low temperature and less sunshine sometimes occurred were negative to returning seedlings, growth and photosynthesis of tobacco plants, causing the adverse effect on the yield and quality. The high temperature and high humidity in late May was easy to cause the occurrence of pests and diseases. At maturi- ty, the meteorological drought caused the nicotine content excessively high in upper leaves, which deteriorated the quality of tobac- co. The main meteorological disasters such as cold waves, strong convections, rainstorms and floods could result in a loss of tobacco production. In addition, services such as forecast during the seedling transplanting period, accurate yield prediction and artificial hail suppression were clearly effective.
