【摘要】 为探索柴胡最佳生产的氮磷钾肥追肥配比，本研究以二年生柴胡为材料，着重分析了柴胡的产量和经济效益。结果表明，叶绿素含量在柴胡不施肥处理间差异显著，而施不同量磷肥和钾肥处理的叶绿素a含量和叶绿素b含量差异不显著，同时缺磷和缺钾均降低叶绿素a含量。特别是，N₃P₂K₂处理下单株生物产量最高，且与N₂P₂K₂、N₂P₃K₂、N₂P₂K₀、N₂P₂K₁和N₂P₂K₃处理差异不显著，而生物产量相较于N₀P₀K₀,N₂P₂K₂、N₂P₃K₂、N₃P₂K₂、N₂P₂K₀、N₂P₂K₁和N₂P₂K₃分别增加了18.86%、18.61%、19.89%、15.96%、16.70%、和18.95%。收获指数和单株生物产量大体上呈相反趋势，其中N₀P₂K₂处理下收获指数和经济系数最高，并与其他处理差异显著。相较于N₀P₀K₀处理，N₂P₂K₂、N₂P₃K₂、N₂P₂K₀、N₂P₂K₁和N₂P₂K₃处理经济效益分别增加了14.65%、14.43%、16.38%、14.25%和13.56%。以药农经济效益为主，N₂P₂K₂是柴胡生产上可采取的最佳施肥方式。更多还原

【Abstract】 To detect the optimal NPK fertilizer application ratio for Bupleurum production, this study utilized the second year Bupleurum as material, focusing on analyzing its yield and economic benefits. The results showed that there were significant difference in chlorophyll content among the treatments of Bupleurum without fertilization. The difference of chlorophyll a and chlorophyll b content among treatments with different amounts of phosphorus（P） and potassium（K）fertilizers was not significant, while both P and K deficiencies reduced chlorophyll a content. In particular, N₃ P₂ K₂ treatment had the highest single plant biomass yield, and was not significantly different from the N₂P₂K₂, N₂P₃K₂, N₂P₂K₀,N₂P₂K₁, and N₂ P₂ K₃ treatments. Compared to N₀P₀K₀, the biomass of N₂P₂K₂, N₂P₃K₂, N₃P₂K₂, N₂P₂K₀, N₂P₂K₁, and N₂ P₂ K₃ increased by 18.86%, 18.61%, 19.89%, 15.96%, 16.70%, and 18.95%, respectively. The harvest index and individual plant biomass generally showed an opposite trend, with the highest harvest index and economic coefficient under the N₀ P₂ K₂ treatment and significant differences compared to other treatments. Compared with the N₀ P₀ K₀ treatment, the economic benefits of the N₂P₂K₂, N₂P₃K₂, N₂P₂K₀, N₂P₂K₁, and N₂ P₂ K₃ treatments increased by 14.65%, 14.43%, 16.38%,14.25%, and 13.56%, respectively. Based on the economic benefits to the medicinal farmer, N₂ P₂ K₂ is the best fertilizer application that can be adopted in the production of Bupleurum.更多还原
