摘要
福建主要烟区土壤、烟叶Ｍｇ、Ｂ含量测定的结果表明，植烟土壤的交换性Ｍｇ含量主要分布在０．２～０．５ｃｍｏｌｋｇ－１，烟叶含Ｍｇ量平均为０．１８％，土壤有效Ｂ含量平均为０．２２ｍｇｋｇ－１，烟叶有效Ｂ含量平均为１１．０５ｍｇｋｇ－１．绝大多数土壤，烟叶都存在着不同程度的缺Ｍｇ、缺Ｂ状况．按每公顷施ＭｇＳＯ４２２５ｋｇ，喷施０．１％硼砂溶液１１２５ｋｇ，可以提高烟叶Ｍｇ、Ｂ含量，增加中上部叶片的单叶重。
The results of this study are summarized as follows: The content of exchangeable magnesium in the soil of main tobacco planting districts, Fujian Province varied from 0.2 to 0.5 cmol·kg -1 , content of magnesium in tobacco leaves was 0.18% in average. Available boron in tobacco planting soil was 0.22 mg·kg -1 in average, In tobacco leaves available boron was 11.05 mg·kg -1 in average. Most of the soil and tobacco leaves were short of magnesium and boron. In the way of applying 225 kg MgSO 4·7H 2O and 1125 kg 0.1% borax per hectare, content of magnesium and boron in tobacco leaves, weight of an upper and middle part leaf, quality and yield could be increased and improved.
