Abstract: 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 150kg/hm², phosphorus (P₂O₅) 150kg/hm², potassium (K₂O) 75kg/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.
