| 摘 要： | 对烤烟植株下、中、上3个部位叶片所经受的光照时数、活动积温和降雨量等生态因子的变化进行了分析.结果表明,随着采收日期的延迟,3个部位烤烟叶片所经受的光照时数、活动积温和降雨量均呈现出随之增加的变化;不同烟叶部位之间累计降雨量的差异不显著,活动积温的差异显著,累计光照时数的差异极显著;不同采收日期之间3个生态因子的差异均极显著.对3个不同部位叶片所经受的生态环境比较看出,以中部叶片经受的活动积温最高(1 639℃)、光照时间最长(530 h)、累计降雨量最多(279mm).相关分析表明,活动积温、累计光照时数、累计降雨量相互之间均呈极显著正相关,而单叶重和均价与累计降雨量、累计光照时数、活动积温之间的相关性均不显著.

| Abstract: | The changes of active temperature, light hours and rains in different flue-cured tobacco leaf positions were analyzed. The results indicated that the active temperature, light hours and rains in different flue-cured tobacco leaf positions were increased with the date delaying of the leaf harvest. The difference of active temperature in different leaf positions was significant and that of light hours were extremely significant. The extremely significant positive correlations were observed among active temperature,light hours and rains. There were no significant correlations between ecological and economic factors. |
