摘    要:目的:研究氮肥(N)、磷肥(P2O5)、钾肥(K2O)配施对柴胡产量的影响。方法:采用三因子二次回归饱和D-最优设计。结果:柴胡生物量的最优施肥方案为氮肥120.3~333.3 kg/hm2、磷肥0~939.45 kg/hm2、钾肥0~227.25 kg/hm2;根冠比的最优施肥方案为氮肥62.66~333.3 kg/hm2、磷肥0~922.54 kg/hm2、钾肥0~227.25 kg/hm2;根产量的最优施肥方案为氮肥34.5~333.3 kg/hm2、磷肥0~939.45 kg/hm2、钾肥0~227.25 kg/hm2。结论:柴胡的产量与氮、磷、钾的施肥量有紧密联系。

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). CONCLUSION: Application quality of nitrogenous, phosphorus and potassium fertilizer are closely related with yield of B. Scorzonerifolium.
