兰州百合优势种植区分布与土壤养分分析

Distribution of Dominant Planting Area of Lanzhou Lily and Its Soil Nutrients Analysis

根据兰州百合适宜生长的环境和原产地、适生地分布,采用实地调查的方式,在兰州市区范围内对兰州百合种植分布及分布区气候、土壤资源状况进行了研究。结果表明,兰州百合在兰州市区范围内主要分布在七里河区的西果园镇、魏岭乡、黄峪镇、阿干镇以及西固区的金沟乡、河口乡。有机质、速效磷、速效钾质量分数处于甘肃省土壤养分分级标准中的四级水平,为较低等级水平,土壤微量元素质量分数为中等水平。

Based on the suitable environment for growth of Lanzhou lily and the distribution of its original and adaptive regions, field investigation on growing distribution,climate condition and soil resources within the scope of Lanzhou City were conducted. The results show that Lanzhou lilies are mainly distributed in the Xiguoyuan Town,Weiling Township,Huangyu Town and Agan Town of Qilihe District,and the Jingou Township and Hekou Township of Xigu District. The mass fraction of organic matter,instant phosphorus and available potassium in the soil nutrient grading standard of Gansu Province was level 4,which was a low level,while the mass fraction of trace elements in soil was in a mediumlevel.
