摘　　要：为探讨野生山豆根生长对养分的需要规律及与生物碱含量之间的关系,以广西河池市凤山县、罗城县和宜州市等地为样点,调查了不同产地山豆根土壤的pH和氮、磷、钾、有机质的含量及山豆根生物碱含量,并进行了相关性分析。结果表明,凤山县的土壤有机质含量和氮含量均为最高。宜州市的土壤全磷和速效磷含量最高,凤山县的土壤全磷和速效磷含量最低。罗城县的土壤全钾含量最高,凤山县的土壤全钾含量最低;宜州市的土壤速效钾含量最高,凤山县的土壤速效钾含量最低。宜州市的山豆根生物碱含量最高,为9.96 mg/g,显著高于凤山县和罗城县的山豆根生物碱含量。不同产地野生山豆根生物碱含量与土壤pH、有机质含量、全磷含量、速效磷含量、全钾含量、速效钾含量呈正相关,但与土壤氮含量呈负相关。综合考虑,在山豆根的人工栽培中应根据实际合理施肥。In order to study the relationship between the nutrient requirement and the alkaloid content of wild Sophora tonkinensis Gagnep.,Fengshan County,Luocheng County and Yizhou City of Hechi City were taken as the sample point.The pH,nitrogen,phosphorus,potassium,organic matter of soil and alkaloid content of wild Sophora tonkinensis were investigated,and their correlation was analyzed.The results showed that the organic matter content and nitrogen content of soil of Fengshan County were the highest.The total phosphorus and available phosphorus content of soil of Yizhou City was the highest,and that of Fengshan County was the lowest.The total potassium content of soil of Luocheng County was the highest,and that of Fengshan County was the lowest.The content of available potassium of soil of Yizhou City was the highest,and that of Fengshan County was the lowest.The alkaloid content of Sophora tonkinensis of Yizhou City was the highest,with 9.96 mg/g,which was higher than that of Fengshan County and Luocheng County.The result of correlation analysis showed that there was a positive correlation between alkaloid content of wild Sophora tonkinensis and the pH,organic matter content,total phosphorus,available phosphorus,total potassium,and available potassium content of soil of different habitats,while the correlations between alkaloid content of wild Sophora tonkinensis and total nitrogen,available nitrogen content of soil were negative.Therefore,reasonable fertilization should be made in production accordance to the actual conditions.
