The Formulation Development And Fertilization Experiment Of Organic Inorganic Compound Special Fertilizer Of Tea

Through collected tea samples in 61 tea samples plot of Mount Wuyi,Fu'an City and Anxi County in different periods,including April,July and October,and then analyzed the content of tea in total nitrogen,total phosphorus,total potassium.Found the ratio of N,P2O5 and K2O on average was 1:0.168:0.529,and this ratio was independent of the site condition of planted tea.According to the ratio of N,P2O5 and K2O of tea and the requirements of organic and inorganic compound special fertilizer developed organic and inorganic compound fertilizer.Making up the organic and inorganic compound fertilizer of tea.The preparation of the organic and inorganic compound fertilizer of tea was including organic matter ? 45%;N + P2O5 + K2O? 20%.Four fertilization modes(organic and inorganic compound fertilizer,organic fertilizer,compound fertilizer,no fertilizer)were set up.The first year used organic and inorganic compound special fertilizer of tea and organic fertilizer to experiment,it was found that whether spring tea or autumn tea,the yield and quality were comparable.But used the organic and inorganic compound special fertilizer had greater and better effect on tea yield and quality than compound fertilizer and contrast,and compound fertilizer was also significantly larger and better than contrast.The second year found that whether spring tea or autumn tea,the yield and quality of tea by using organic and inorganic compound fertilizer was significantly greater and better than organic fertilizer,compound fertilizer and contrast.Used organic fertilizer to experiment,it was found that whether spring tea or autumn tea,the yield and quality of tea was significantly greater and better than compound fertilizer and contrast.Used compound fertilizer to experiment,it was found that the yield and quality of tea was significantly greater and better than contrast.The use of appropriate amounts of organic and inorganic compound special fertilizer of tea and organic fertilizer to experiment both improved the yield and quality of tea.However,because the planting site of tea in Fujian Province are mostly distributed in the hills and mountains,the application organic and inorganic compound special fertilizer of tea can effectively reduce the cost of transporting and transporting.
