【摘要】 为寻求迷迭香种植的最佳施肥方案，本研究以3年生迷迭香植株为材料，采用“3414”施肥试验设计，分析了不同施肥处理对迷迭香产量的影响。以N、P、K施肥量（分别以N、P₂O₅、K₂O计）与产量进行拟合分析，产量与N、P、K肥之间存在极显著回归关系，三元二次肥料效应方程模型为Y_NPK=1.764 7+0.321 5 X_N+0.278 0 X_P+0.031 1 X_K-0.033 6 X²_N-0.138 2 X²_P-0.002 9 X²_K+0.027 9 X_NX_P+0.004 3 X_NX_K+0.022 3 X_PX_K。由三元二次肥料效应方程求得当N、P₂O₅、K₂O的施用量分别为8.09、3.93、26.13 g·m^-2时，迷迭香产量最高，为4.01 kg·m^-2。采用频次分析方法对模型进行优化，获得优化后的施肥方案：N为5.18～7.30 g·m^-2,P₂O₅为2.69～3.79 g·m^-2,K₂O为15.53～21.89 g·m^-2。本研究为迷迭香施肥工作提供了科学且具实操性的技术指导。更多还原

【Abstract】 To seek the best fertilization solution for Rosmarinus officinalis（rosemary） cultivation, this study taked 3-year-old rosemary plants as material and adopted the “3414” fertilizer experimental design to analyze the effects of different fertilization treatments on rosemary yield.The fertilization amounts of N, P and K（in terms of N, P₂O₅ and K₂O, respectively） were fitted to the yield, and there was a highly significant regression relationship between yield and N, P and K fertilizers, and the model of the ternary quadratic fertiliser effect equation was: Y_NPK=1.764 7+0.321 5 X_N+0.278 0 X_P+0.031 1 X_K-0.033 6 X²_N-0.138 2 X²_P-0.002 9 X²_K+0.027 9 X_NX_P+0.004 3 X_NX_K+0.022 3 X_PX_K.Based on the fertilizer effect equation, when the fertilization amount of N, P₂O₅ and K₂O were 8.09, 3.93 and 26.13 g·m^-2 respectively, the maximum yield of rosemary was 4.01 kg·m^-2.The frequency analysis was used to optimize the model, and the optimal fertilization scheme was as follows: 5.18 to 7.30 g·m^-2 of N, 2.69 to 3.79 g·m^-2 of P₂O₅, and 15.53 to 21.89 g·m^-2 of K₂O.This study aimed to provide scientific and technical guidance for the fertilization of rosemary.更多还原
