Effects of Combined Application of NPK Fertilizers on Yield and Quality of Blumea balsamifera
In order to provide a technical support and theoretical reference for large-scale cultivation of B.balsamifera,the authors used ‘3414 ’ fertilization program and the gas chromatography to study the effects of different nitrogen-phosphorus-potassium combination on yield and quality of B.balsamifera.Results:Nitrogen-phosphorus-potassium combination treatments significantly increased the yield of B.balsamifera and promote the accumulation relative contents of l-borneol,the treatment of N2P2 K2 was of the highest yield,which the nitrogen 16.71 kg/667m2,phosphorus 24.91 kg/667m2,potassium 12.40 kg/667m2 is the optimum fertilization level;the B.balsamifera biological yield and economic yield were respectively 1 325.66 kg/667m2and 133.35 kg/667m2,the relative content of l-borneol was 3.84 mg/g,only lower than N2 P2K1 (4.38 mg/g) the success of the fertilization treatments ranked as NPK＞NK＞NP＞PK.Nitrogen had the greatest influence on B.balsamifera yield,followed by potassium and phosphorus.Considering the yield and the relative content of l-borneol,and the fertilizer utilization rate of N, P,K,it is recommend that N2P2K2(N ∶ P ∶ K=1 ∶ 1.49 ∶ 0.74).
