| 摘 要： | 通过野外调查与室内分析相结合的方法，对不同利用方式下贵州钩藤产地土壤养分差异进行对比研究。结果表明：3 种土地利用方式下，土壤pH 值均呈强酸性，其值大小表现为：自然林地>荒草地>钩藤基地，土壤有机质、土壤全氮、碱解氮均表现为：钩藤基地>荒草地>天然林地，有效磷含量差异表现为：荒草地> 钩藤基地>天然林地。总体来看，贵州钩藤产地的土壤养分处于中等状态。pH 值与有机质、全氮、碱解氮、有效磷、速效钾之间存在负相关性，全氮与碱解氮、有效磷呈极显著正相关性，全氮与速效钾呈正相关性，碱解氮与有效磷、速效钾呈极显著正相关性，有效磷与速效钾呈极显著正相关性。研究结果为钩藤产地土壤改良和提供高产优质的钩藤栽培技术提供理论基础。

Charateristics of nutrient content in soil in
uncaria origins from Guizhou |

| Abstract: | The soil nutrient differences for uncaria under different types of land utilization in Guizhou province were
analyzed by field investigation and indoor analysis. Results indicated that the soil in three types of land utilization were
strongly acid soil. The soil pH value, organic matter, total nitrogen and available nitrogen, available phosphorus content
under different land utilization were natural forest land > grassland > uncaria base, uncaria base > grassland > natural
forest land, grassland>uncaria base>natural forest land, respectively. In general, the soil nutrient of uncaria in Guizhou
province was suitable. Significant negative correlations existed between pH value and organic matter, total nitrogen,
available nitrogen, available P content, available K content. Significant negative correlations were found between total
nitrogen and available nitrogen, between total nitrogen and available P content, between available nitrogen and available P
content, between available nitrogen and available K content, available P content and available nitrogen content, available P
and available K content. The research results can provide the theoretical basis for soil improvement in uncaria base and the
cultivation techniques with high yield and good quality for uncaria. |
