摘　　要：试验表明，烟叶中的钙和铁含量随钙和铁施用量的增加而增加，烟叶中钙含量达到６１２ｇ·ｋｇ－１，铁含量最高达到１５５７５ｍｇ·ｋｇ－１随土壤施钙量、施铁量增加，中部烟叶中锰、锌、镁等含量随之增加，烟叶中铜的含量随之减少。钙和铁的施用对烟叶中钾的含量影响不大。在石灰性土壤上，施钙、镁肥对烟草都是负效应。The results of experinemts showed Ca and Fe contents in tobacco leaf increased with the increment of Ca and Fe application amount in soil.The highest Fe the content reached 6.12 g·kg -1 ,and the hightest Fe content reached 1 557.7 mg·kg -1 .The content of mineral nutrition like Mn,Zn,Mg in tobacco leaf increased and Cu content dcreased with the increment of Ca and Fe application amount.Ca and Fe fertilizers application had little effect on K content in tobacco leaf.It is suggested that as Ca and Fe application in the soil of Henan Province have negative correlation wifth tobacco yield ,Ca and Fe fertilizers application should be avoided in production.
