Chinese. 对湖北省123个典型茶园土壤进行取样和分析测定，结果表明：湖北省茶园土壤潜在酸化严重，土壤pH值在4以下的茶园占49．6％；土壤有机质、碱解氮和速效磷含量丰富；46．6％的茶园土壤速效钾亏缺；27．1％的茶园土壤有效镁含量偏低；微量元素中，土壤有效铁含量适中，有效铜亏缺严重，83．1％的茶园土壤有效铜含量低于1mg／kg，1／3以上的茶园土壤有效锰和锌含量偏低。改善茶园土壤的酸化状况，加强对钾、镁、铜、锰和锌的施用是提高湖北省茶园茶叶产量和品质的关键。[著者文摘]

The results indicated that soil acidification was severe with 49. 6 % of the soil pH lower than 4. Soil organic matter, total nitrogen,available nitrogen, total phosphorus, available phosphorus and available calcium were abundant. 46.6 % of soil potassium was deficient and 27.1% of soil available magnesium was lower. Concentration of soil available iron was moderate,soil available copper was seriously deficient and 83. 1% of soil available copper was less than 1 mg/kg. 1/3 of the soil available manganese and available zinc content were approximately lower. Amelioration the soil acidification and increase the application of fertilizer potassium, magnesium, cooper,manganese and zinc are critical for improving the yield and quality of tea of tea plantation in Hubei Province.
