| 摘 要： | 对攀枝花烟区750份耕层土壤样品进行了交换性钙、镁的分析.结果表明:攀枝花市植烟土壤交换性钙含量在0.07 ～19.67 cmol/kg范围内,平均为2.49 cmol/kg,有47.73％的植烟土壤交换性钙总体较缺乏.土壤交换性镁含量在0.03～6.03 cmol/kg范围内,平均为0.97 cmol/kg,交换性镁容量缺乏土壤占28.40％.土壤交换性钙镁比在0.06～24.88范围内,平均为3.21,有87.87％的土壤存在生理性缺钙的风险.土壤交换性钙含量和交换性钙镁比值与海拔高度之间均存在显著负相关关系.

| Abstract: | 750 soil samples from Panzhihua tobacco-growing areas were analyzed about exchangeable calcium and magnesium.The results showed that the content range of soil exchangeable calcium was from 0.07 cmol/kg to 19.67 cmol/kg,and the average content was 2.49 cmol/kg,and 47.73 % of the soils were deficient in calcium.The content range of soil exchangeable magnesium was from 0.03 cmol/kg to 6.03 cmol/kg,and the average content was 0.97 cmol/kg,and 28.40 % of the soils was deficient in magnesium.The ratio of soil exc... |
