我国初烤烟叶钾含量现状与变化趋势分析

摘要

选取2002～2016年16个烤烟生产省(直辖市)代表产地烤烟样品86361份,研究了我国不同省份2012～2016年烟叶钾含量现状以及2002～2016年烟叶钾含量变化趋势.结果表明,2012～2016年全国烟叶钾含量整体偏低,尤其是内蒙古、黑龙江、河南、山东、吉林、陕西烟叶钾含量低的问题较为突出;云南、重庆、四川、湖北、贵州、辽宁、安徽烟叶钾含量处于中等水平;湖南、江西、福建烟叶钾含量相对较高.2002～2012年全国烟叶钾含量在波动中缓慢上升,2012年后趋于平稳,但是安徽烟叶钾含量出现波动中缓慢下降趋势.%In this study, 86361 flue-cured tobacco leaf samples were collected from 16 tobacco-producing provinces ( mu-nicipalities) in China, and the current situation of the potassium contents in these samples during 2012～2016 and the variation trend of the potassium contents in these samples from 2002 to 2016 were analyzed. The results showed that:for the flue-cured to-bacco leaf samples collected during 2012～2016, their potassium contents were relatively low in general in China, were very low in Inner Mongolia, Heilongjiang, Henan, Shandong, Jilin and Shaanxi provinces, were at middle level in Yunnan, Chongqing, Sichuan, Hubei, Guizhou, Liaoning and Anhui provinces, and were relatively high in Hunan, Jiangxi and Fujian provinces. From 2002 to 2012, the potassium contents in the flue-cured tobacco leaf samples in China increased slowly in fluctuation; since the year 2012, the potassium contents tended to be smooth and steady, except that the potassium content in the flue-cured tobacco leaf samples from Anhui decreased slowly in fluctuation.
