摘要
通过对河南植烟土壤和烟叶中磷、钾、钙、镁、氯、铁、锰7种矿质元素进行的相关分析表明:(1)土壤中各元素含量,以河南周口和商丘的全磷、全镁和水溶性氯含量较高,三门峡的全钾、全钙、全铁和全锰含量较高,济源的全钾、全铁含量较高,南阳的全锰含量较高;以郑州的全磷、全镁、全铁和全锰含量最低,信阳的全钾和全钙含量最低,三门峡水溶性氯含量最低;其中磷、钙、氯、锰含量的变异系数均超过了40%。(2)多数烟叶中钾含量偏低;烟叶中磷、钙、镁、氯、铁、锰含量较为适宜;烟叶中锰、氯、铁、镁含量变异系数较大。(3)土壤全钾、全钙、全镁含量对烟叶中7种矿质元素含量影响最大,全磷、全铁、全锰含量影响次之,水溶性氯含量影响最弱。
Relationship between mineral elements contents in the soil and flue-cured tobacco leaves in Henan was an- alyzed. Results showed that soil total P and klg contents as well as water soluble C1 contents in Zhoukou and Shan- gqiu was the highest, whereas soil total K, Ca, Fe and Mn contents in Sanmenxia was higher than other places. Soil total K and Fe contents in Jiyuan were the highest, and soil total Mn in Nanyang was the highest. Soil total P, Mg, Fe and Mn contents in Zhengzhou was the lowest and total K and Ca contents in Xinyang as well as water soluble C1 content in Sanmenxia was the lowest. The variation coefficients of soil total P, Ca, Mn contents as well as water solu- ble C1 contents were higher than 40%. Potassium contents in tobacco leaf of most samples were lower than the stand- ard. The contents of P, Ca, Mg, C1, Fe and Mn contents in tobacco leaf were appropriate. Variation coefficients of Mn, C1, Fe and Mg contents were the highest. The contents of soil total K, Ca and Mg had the biggest effects on the seven mineral elements contents in flue-cured tobacco leaves, and soil total P, Fe, and Mn took the second place, and soil water soluble C1 content had the lowest effect.
