摘　　要： 通过实地采样、实验室化验分析,研究了山东省主要绿茶产区日照、青岛、潍坊各地茶园土壤养分的含量状况。结果表明,茶园土含速效氮78.25mg/kg,全氮0.0823%,有机质1.307%,速效磷61.03mg/kg,速效钾124.23mg/kg。微量元素铁、锰、铜、锌有效量较高,但总量均低于全国平均水平。全铁0.012%,全锰435.39mg/kg,全铜13.84mg/kg,全锌44.48mg/kg,有效铁78.18mg/kg,有效锰53.75mg/kg,有效铜1.34mg/kg,有效锌2.93mg/kg。微量元素和磷钾水平含量较高,明显超过了优质高效茶园养分水准,但是氮素和有机质的含量还处于较低水平。 Soil nutrients of green tea gardens were determined and analyzed in Rizhao, Qingdao and Weifang cities, Shandong province. The results showed that the contents of rapidly available N, P and K, total N and organic matter were 78.25 mg/kg, 61.03 mg/kg, 124. 23 mg/kg, 0. 0823% and 1. 307% respectively. The available contents of microelements Fe, Mn, Cu and Zn were 78. 18, 53.75, 1.34 and 2.93 mg/kg respectively, while those total contents lower were 0. 012%, 435.39 mg/kg, 13.84 mg/kg and 44.48 mg/kg respectively. In conclusion, the contents of microelements, P and K were apparently more than that of high quality tea garden, but the contents of nitrogen and organic matter were still lower.
