Modeling for the Optimization of Fertilization of Tea High Yield

The return two times set up juices optimumly trying to adopt“311-B”,a three-factor (N,P,K)substrate cultivation experiment was conducted by using tea.The regression equations of the relationship between N,P,K and the effects on the yield were established.The results indicated that the yield of tea would increase with high nitrogen supply,and P,K had certain effects on it,the order is NPK,the interactions of N-P,N-K and P-K to the yield were significant.Considering both the yield and quality of the hot pepper,the combinations of N,R K were optimized as follows:N:0.406~0.435 g/kg soil,P2O5:0.159~0.170 g/kg soil,K2O:0.186~0.198 g/kg soil,and N:P2O5:K2O was 1:0.39:0.46.
