摘 要: 充分了解崂山茶区茶园土壤的养分水平,对合理施肥、提高茶叶产量和品质有极其重要的指导意义。根据崂山绿茶重点种植区内茶园土壤的实测数据,分析了土壤有机质、碱解氮、速效磷、速效钾的分布特征及季节变化动态,并运用SPSS软件,对所选茶园的土壤养分水平进行方差分析和聚类分析。结果表明,茶园土壤养分指标因季节和地点的不同存在显著差异,根据聚类分析结果,可将茶园按土壤养分水平分为高、中、低三等,且不同等级的茶园养分均呈现明显的年变化趋势。 The research about the soil nutrient level of Laoshan tea garden was very important to improving quantity and quality. Soil samples from tea gardens located in Laoshan green tea planting area were tested, and the distribution and the seasonal dynamic changes of the soil organic matter, available nitrogen, phosphorus and potassium of those samples were analyzed with variance analysis and cluster analysis by SPSS. The results showed that the tea garden soil nutrients of different seasons and different locations had significant difference. The soil nutrient level in chosen tea gardens could be clustered into three types by cluster analysis. Also soil nutrient in different tea garden was found to have a distinct annual variation trend.
