湖南烟区异常褪绿发白烟叶中、微量元素含量

Secondary and Trace Elements Contents in Different Parts of Abnormal Faded Green Flue-cured Tobacco Leaves in Hunan Area

对湖南省嘉禾县广发镇、普满镇,江永县兰溪乡,桑植县和龙山县5个植烟地成熟期异常褪绿发白烟叶的中、微量元素进行了取样分析。结果表明:铜和锌含量适宜;锰、钙含量主要在适中和较低的范围;铁含量主要在较高和适中的范围;镁含量偏低。中、微量矿质元素在异常褪绿发白烟株不同部位的分布比较有规律,铜、锰、锌、铁、钙元素的含量随烟叶部位上升而下降,镁元素的含量随烟叶部位上升而上升。

Abnormal faded green flue-cured tobacco leaves during maturation period were sampled in five tobacco planting areas of Hunan the town of liahe, the town of Puman, the town of Jiangyong, Sangzhi and Longshan county, seeondary and trace elements in tobacco leaves were analyzed. The results showed that the contents of copper and zinc are appropriate, the contents of manganese and calcium are mainly in range of medium and low, the iron content is high and moderate; magnesium content is low. The distribution of secondary and trace mineral elements in abnormal faded green of different parts of tobacco plant is regular. Copper, manganese, zinc, iron, calcium content is rising while the part of tobacco leaf is falling, magnesium content is increasing while the part of tobacco leaf is falling.
