发布时间：2018-08-23 19:49
【摘要】：【目的】本研究对云南红河州8个县市烟叶基地300个土壤样品和900份烟样进行指标检测。【方法】采用SPSS19.0对数据进行统计描述和相关性分析,系统阐述红河不同烟区烟叶品质及土壤中微量元素的特征,并深入挖掘红河烤烟烟叶品质与土壤养分的相关关系。【结果】红河州不同烟区土壤中微量元素含量变异较大,其中有效锌和有效锰变异最为明显;红河烟区烟叶总氮、烟碱、总糖、还原糖、烟叶钾、氯元素、石油醚和淀粉呈现不同程度的变异,其中氯离子变异极为明显。【结论】红河植烟土壤不同中微量元素对烟叶化学组成影响不同,其中交换性镁及交换性钙与上、中、下部位烟叶钾均呈负相关,有效锰与3个部位烟叶总氮含量均呈现负相关。
[Abstract]:[objective] to detect 300 soil samples and 900 tobacco samples from tobacco base in 8 counties of Honghe Prefecture, Yunnan Province. [methods] the data were statistically described and analyzed by SPSS19.0. The characteristics of tobacco leaf quality and trace elements in soil in different tobacco areas of Honghe were systematically expounded, and the correlation between tobacco quality and soil nutrients was deeply explored. [results] the content of trace elements in different tobacco regions of Honghe had great variation. Total nitrogen, nicotine, total sugar, reducing sugar, potassium, chlorine, petroleum ether and starch of tobacco leaves in Honghe tobacco area showed different degrees of variation, among which available zinc and available manganese were the most obvious, and the variation of total nitrogen, nicotine, total sugar, reducing sugar, potassium of tobacco leaf, chlorine element, petroleum ether and starch were different. [conclusion] different trace elements in Honghe tobacco planting soil have different effects on chemical composition of tobacco leaves, among which exchangeable magnesium and exchangeable calcium are negatively correlated with upper, middle and lower parts of tobacco leaf potassium. There was a negative correlation between available manganese and total nitrogen content in three parts of tobacco leaves.
