摘　　要：通过水泥池培育方法,进行初期投产茶园氮磷钾肥料配比试验。结果显示,氮磷钾不同配比施用对幼龄茶树生长性状及茶园产量影响很大,处理间差异均达到显著或极显著水平;氮磷钾肥不同水平配施或单因素施入对茶树芽叶生化成分影响显著,随着氮肥施入量的增加,氨基酸含量有明显提高;磷钾肥对提高红茶品质有着较大的作用,单施氮肥将使红茶品质变差。最终分析得出初期投产茶园以每年施纯氮150 kg/hm2、磷(P2O5)150 kg/hm2、钾(K2O)75 kg/hm2效果最好,在此施肥水平下,不仅茶叶产量、品质得到提高和改善,同时增强幼龄茶树的树势,为成龄茶园丰产打下基础。Through the cement pond cultivation method to conduct the NPK fertilizer ratio test in the initial production tea garden,the results indicated that different proportions of NPK fertilizers showed a great influence on the growth characters and yield of tea plant.The difference between the treatments was significant or very significant;single application or matching application with different levels of NPK fertilizer affected biochemical composition of the shoots significantly.The amino acids significantly increased,with increasing of the amount of applied nitrogen.Application of P and K improved the quality of black tea,but separate application of N fertilizer reduced the quality of black tea.The final conclusion showed a good effect for tea production in the initial production tea garden with application fertilizer pure nitrogen per year 150 kg/hm2,phosphorus（P2O5） 150 kg/hm2,potassium（K2O） 75 kg/hm2,under this fertilizing level,not only the production and quality were increased and improved,the growth potential of young tea plant was also enhanced,thus laying the foundation for mature garden to gain high yields.
