摘　　要：为提升茶园土壤质量,该研究采集了一系列不同植茶年份的土壤,以探究杭州市富阳区茶园土壤质量随植茶年份的变化情况。根据国家第二次土壤普查提出的土壤养分评价标准对本研究茶园土样养分状况进行丰缺性评价;引入单因子污染指数法和Nemerow综合污染指数法来评价金属污染情况。结果表明,常年植茶会导致土壤pH值下降,而土壤中有机质含量随植茶时间增加上升,有效磷呈下降趋势,全氮和速效钾含量先上升后下降。微量元素中有效铁、有效锰、有效锌和有效铜含量均增加。据此研究结果,可以为更好地施用肥料、肥力维护和改良土壤提供数据支撑。In order to improve the soil quality of tea gardens,a series of soils of different tea planting years were collected in this study to explore the changes of soil quality of tea gardens in Fuyang District of Hangzhou with tea planting years.According to the evaluation criteria of soil nutrients proposed by the second national soil survey,the nutrient abundance and deficiency of tea garden soil samples were evaluated.The single factor pollution index method and Nemerow comprehensive pollution index method were introduced to evaluate the metal pollution.The results showed that perennial tea planting would lead to a decrease in soil pH value,while organic matter content in soil increased with the increase of tea planting years,available phosphorus showed a decreasing trend,total nitrogen and available potassium contents increased first and then decreased.The content of available iron,available manganese,available zinc and available copper in trace elements increased.The results of this study can provide data support for better fertilizer application,fertility maintenance and soil improvement.
