2010年南平市异常气候对烤烟生长发育和产量的影响

通过分析2010年南平市烤烟生长发育期间气温、降水、日照3个主要气候因子对烤烟生产的影响,结果表明：3月平均气温、光照和降雨正常,但出现的冰雹对部分烤烟造成灾害;4月低温多雨,不利于烟株早生快发;5月多剧烈天气,冰雹、大风、强雷电等强对流天气多发,灾情较严重,对烤烟造成重大不利影响;6-7月光照不足,低温多雨不利于干物质累积,影响品质;6月中、下旬南平市出现持续性暴雨、大暴雨、局部特大暴雨,各县市均出现严重的洪涝灾害,给烤烟生产造成了严重损失。总体来说,2010年南平市烤烟生产的农业气候条件较差,烟叶产量和质量都下降。

Effects of abnormal climate on the growth and yield of flue-cured tobacco in Nanping in 2010

According to the comprehensive analysis of the effects which caused by air temperature,rainfall and sunlight on flue-cured tobacco during its growth period in Nanping in 2010,the average temperature,sunlight and rainfall in March was normal,but the hail damaged partial flue-cured tobacco.Meanwhile low temperature and rainy days were bad for earlier growth and faster development in April.The strong convection weather like hail,strong wind and strong thunder et caused serious disaster to flue-cured tobacco in May.Lack of sunlight and relatively low temperature and rainy days were bad for dry matter accumulation and quality in June and July especially the persistent heavy rainstorm in the middle and last ten days of June caused severe damage to flue-cured tobacco.As a whole,the conditions of agricultural climate of Nanping were relatively poor in 2010,the yield and quality of tobacco leaf declined.
