The experiment was conducted as orthogonal design in 4 factors 3 levels with the organic and inorganic
fertilizer The results
showed that applying organic and inorganic
fertilizer coordinately could promote the fast growth of
Tie Guanyin,enhance the productivity and the quality The best combination were N 3P 1K 3RC 3 or N 2P 2K 2RC 3 Effects of N,P,K and RC on tea plant growing in every stage were different K was the main fertilizer factor of diameter increament of young tea tree N played the most effective role on yield of mature tea tree,the second was K.It was the main fertilizing factor to affect quality then RC Effect of different fertilizer treatments on the biochemical content and ratio of mature tea tree were different The correlation coefficient of water extraction,caffeine,polyphendes,reducing sugar,ester extraction,catechin with quality were 0 7799,0 7268,0 6651,0 6151 and 0.6589, 0 5783,respectively Applying organic and inorganic fertilizer coordinately and increasing the dose of K properly was an important way for Tie Guanyin tea plant.
