为探究气候因子对湘东烟区烤烟氯、钾含量的影响,对茶陵县2012—2018年间烤烟氯、钾含量及其与主要气候因子之间的关系进行了分析。结果表明,湘东茶陵烟区烤烟大田期平均气温23.0℃,≥10℃活动积温2 909.5℃,降雨量865.6 mm,日照时数529.5 h,属于适宜种植优质烤烟地区。2012年至2018年钾含量均处于适宜范围内,部分年度中、下部烟叶氯含量偏低。相关分析表明,上部烟叶氯含量与上部叶采收期气温、≥10℃积温、≥20℃积温显著负相关;中部烟叶氯含量与伸根期≥20℃积温显著正相关,而钾含量与下部叶采收期和大田期≥10℃积温显著正相关;下部烟叶钾含量与伸根期气温和≥10℃积温显著正相关;氯、钾含量...

In order to explore the effect of climate factors on the contents of potassium and chloride of flue-cured tobacco in eastern Hunan,the relationship between the contents of chlorine and potassium in flue-cured tobacco and the main climatic factors was analyzed from 2012 to 2018 in Chaling.During the field period of tobacco in Chaling,the average temperature was 23.0 ℃,≥ 10 ℃ accumulated temperature was 2909.5 ℃,the rainfall was 865.6 mm and sunshine hours were 529.5 h.The results showed that Chaling is a high-quality flue-cured tobacco culti...
