日照茶树种植区表层土壤营养元素地球化学特征分析

Analysis on Geochemical Characteristics of Nutrient Elements in Surface Soil in Rizhao Tea-planting Areas

对土壤中的营养元素进行分析,对于茶树种植及宜种性评价意义深远。该研究主要是利用1 km×1 km表层土壤采样数据,借助地统计学和GIS技术对日照茶树种植区表层土壤中主要营养元素的地球化学特征进行分析。结果表明,研究区N,P,K2O,S含量相对较丰富,而其他营养元素相对较贫乏;营养元素富集区大致以西湖、秦楼、岚山头3个镇为顶点呈三角分布。

Analyzing soil nutrient elements is quite meaningful to tea-planting and its suitability assessment.By using 1km×1km sampling datas of surface soil in Rizhao tea-planting areas,using geostatistics together with GIS method,geochemical characteristics of major nutrient elements in surface soil in Rizhao tea-planting areas are analyzed.It is showed that the content of N,P,K2O,S elements are comparatively abundant in research area,while other nutrient elements are scarce.The enrichment zones of nutrient elements are like a triangular whose vertexes are Xihu county,Qinlou county and Lanshantou county.
