本研究以云南圭山山脉地区的弥勒县、泸西县、石林县(以昆明市作为对照)土壤及饲用植物为对象,分析主要矿物元素在土壤和饲用植物中的组成及质量分数,探讨该地区主要矿物元素在土壤及饲用植物中的分布规律。结果表明,与昆明地区相比,云南圭山山脉地区土壤中含有较高的锶、钾、镁、钼和氟元素,而磷、铁、锌、铜与钴元素质量分数较低;同时饲用植物中含有较高的锶、镁、铁、锌、铜、锰元素,而磷元素质量分数较低;磷、钙、镁与锶元素质量分数在土壤与饲用植物间存在显著的正相关,表明该地区饲用植物中钙、磷、锶与镁元素较多来自土壤中。
In this study, the soil and forage plants in Maitreya County, Luxi County and Shilin County in Kuniganshan Mountains of Yunnan Province were used as the objects to analyze the composition and mass fraction of main mineral elements in soil and forage plants, To explore the distribution of the main mineral elements in the soil and forage plants in the area. The results showed that compared with the Kunming area, the soil in the Guishan Mountains of Yunnan Province had higher contents of strontium, potassium, magnesium, molybdenum and fluorine while the phosphorus, iron, zinc, copper and cobalt contents were lower; The plants contain higher content of strontium, magnesium, iron, zinc, copper and manganese, while the phosphorus content is lower. The content of phosphorus, calcium, magnesium and strontium is positively correlated with soil and feed plants, It shows that the forage plants in the area have more calcium, phosphorus, strontium and magnesium from the soil.
