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1 mg/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。
The sampling and analysis of 123 typical tea plantation soils in Hubei Province showed that the potential acidification of the tea plantation in Hubei Province was serious with 49.6% of the tea plantations with soil pH value below 4. The content of soil organic matter, available nitrogen and available phosphorus were abundant. % Of tea plantation soils were deficient in available potassium, 27.1% of tea plantation soils were low in available magnesium, moderately available iron in trace elements was moderate, available copper was severely depleted, and 83.1% of available tea soils contained less than 1 mg / kg of available copper , More than 1/3 of the tea plantation soil effective manganese and zinc content is low. Improving the acidification status of tea plantation soils and strengthening the application of potassium, magnesium, copper, manganese and zinc are the keys to improve the yield and quality of tea plantations in Hubei Province.
