对云南省普洱市具有代表性茶园的40个土样进行了调查分析,测定了土壤养分含量状况,结果显示:普洱市茶园土壤pH值的变化范围在3.97~5.77之间,土壤中有机质、碱解氮、有效磷以及速效钾含量的平均值分别是23.40 g kg-1、67.03 mg kg-1、30.40 mg kg-1和85.46 mg kg-1,土壤养分含量水平表明普洱市茶园土壤适宜茶树的种植,但是土壤碱解氮和速效钾的含量相对偏低,在今后普洱市茶园的养分管理中,应采取“增施氮肥,稳定磷肥,补充钾肥”的土壤养分管理措施。
40 soil samples from representative tea plantations in Pu’er City of Yunnan Province were investigated and analyzed. The status of soil nutrient content was determined. The results showed that the pH range of tea plantation in Pu’er City ranged from 3.97 to 5.77. The content of soil organic matter, The average contents of nitrogen, available phosphorus and available potassium were 23.40 g kg-1, 67.03 mg kg-1, 30.40 mg kg-1 and 85.46 mg kg-1, respectively. The soil nutrient content showed that the tea plantation in Pu’er City was suitable for tea plantation However, the content of soil available nitrogen and available potassium is relatively low. In the future, the nutrition management of tea plantation in Pu’er should adopt the soil nutrient management measures of “increasing nitrogen fertilizer, stabilizing phosphate fertilizer and potassium fertilizer”.
