Abstract
OBJECTIVE
To study the effect of different fertilizer assortment (nitrogenous, phosphorus and potassium) on Bupleuram scorzonerifolium yield.
METHODS
Three factors were designed by quadratic regression and D-optimum designation.
RESULTS
As far as the biomass concerned, the best design of fertilizer was N 120. 3 - 333. 3 kg/hm(2) P2O5 0-939. 45 kg/hm(2), K2O 0 - 227. 25 kg/hm(2). As to R/T, the best design was N 62. 66 -333. 3 kg/hm(2), P2O5 0 -922. 54 kg/hm(2) , K2O 0 -227. 25 kg/hm(2). And for the root weight, the best design was N 34. 5 -333. 3 kg/hm(2), P2O5, 0 -939. 45 kg/hm2 , K2O 0-227. 25 kg/hm(2).
CONCLUSIONS
Application quality of nitrogenous, phosphorus and potassium fertilizer are closely related with yield of B. Scorzonerifolium.
