摘 要: 广东茶区茶园土壤检测结果表明,广东茶区茶园土壤肥力偏低,60%以上茶园土壤有机质含量偏低至极缺乏,70%以上土壤碱解氮偏低至极缺乏,50%以上茶园土壤速效磷含量偏低至极缺乏,80%以上茶园土壤速效钾含量偏低至极缺乏。根据广东茶区茶园土壤养分现状,需要提高茶园土壤肥力,增加茶园土壤有机质,合理施用氮、磷肥,重视施用钾肥,平衡施肥才能获得茶叶高产、优质、高效益。 The results of soils nutrition in tea orchards indicated that soil fertility showed quite low in Guangdong province.More than 60%,70%,50% and 80% of soils in tea orchards were low in organic matter,alkalytic N,available P and available K concentrations,respectively.Even,some evidenced extremely deficiency.According to the present situation of soils nutrition in Guangdong tea orchards,in order to achieve the goal of high output,quality and efficiency,it is necessary to improve the fertility by increasing the organic matter,balancing the nitrogen,phosphate and potash fertilizer.
