Abstract: 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 N>P>K, 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: 0.406~0.435βg/kg soil, P2O5: 0.159~0.170βg/kg soil, K2O: 0.186~0.198βg/kg soil, and N:P2O5:K2O was 1:0.39:0.46.
