摘　　要：对"金神农"烟区近年来的气候特征进行了分析,并采用典型相关分析研究了2000—2013年气象条件对烟叶品质的影响。结果表明:(1)"金神农"烟区烟叶大田生长期热量条件和水分条件可以较好地满足优质烟叶生长需求。(2)气温和降雨量是影响"金神农"烟叶糖碱的主要因子,烟叶生长前期气温、大田期≥10℃积温的增加,烟叶进入旺长期后气温及各生育期降雨量的降低有利于金神农烟叶烟碱的合成和积累,而不利于总糖的积累。(3)烟叶感官质量与烟叶生长前期温度和各生育期日照时数正相关,而与烟株生长后期温度和成熟期降雨量负相关。The climatic conditions in Jinshennong tobacco-producing area were analyzed and the influences of climatic conditions on tobacco quality were studied by using canonical correlation analysis.The results indicated that：（1） The heat and moisture conditions during tobacco field growth period were suitable for high quality tobacco growth.（2） Temperature and rainfall were the main factors affecting the contents of total sugar and nicotine of tobacco.With temperature during earlier stage and ≥10 ℃ accumulated temperature during field period increasing,temperature after tobacco fast growing period and rainfall during every tobacco growth stages decreasing,the nicotine content increased and total sugar content declined.（3） For tobacco sensory quality,temperature during tobacco early growth stage and sunshine hours during every tobacco growth stages had positive effects,and temperature during tobacco late growth stage and rainfall during tobacco mature period had negative effects.
