采用D-饱和最优设计，建立朝鲜淫羊藿叶产量与氮磷钾配施的回归模型，并结合因素频率分布，研究氮磷钾配施对朝鲜淫羊藿叶产量及淫羊藿苷和总黄酮2种质量指标含量的影响。在盛花期和初果期磷肥对产量贡献最大，果熟期氮肥对产量贡献最大，而在果后的绿叶期钾肥对产量的贡献最大。寻优结果表明:每株叶产量＞1 g，95％置信区间所对应的优化施肥量为N 12。89～17。30 kg/667m2、P2O5 16。45～19。90 kg/667m2、K2O 17。24～20。82 kg/667m2;淫羊藿苷含量＞1％，95％置信区间所对应的优化施肥量为N 6。46～15。80 kg/667m2、P2O5 8。88～17。26 kg/667m2、K2O 9。35～19。25 kg/667m2;总黄酮含量＞20％，95％置信区间所对应的优化施肥量为 N 12。83～18。57 kg/667m2、P2O5 12。85～18。32 kg/667m2、K2O 16。78～21。01 kg/667m2。合理的氮磷钾配施不仅能促进朝鲜淫羊藿单株叶片产量的提高，而且对于保证其药材质量具有明显作用。综合考虑氮磷钾配施对朝鲜淫羊藿产量和质量的影响，得出朝鲜淫羊藿优质生产的施肥量为N 12。89～15。80 kg/667m2、P2O5 16。45～17。26 kg/667m2、K2O 17。24～19。25 kg/667m2，N、P2O5、K2O 的最优施肥量配比为 1∶(1。04～1。34)∶(1。34～1。49)。
Effects of N,P and K Combined Application on Yield and Quality of Epimedium koreanum
To explore the optimal application rate of nitrogen(N),phosphorus(P)and potassium(K)in the cultivation of Epimedium koreanum,and to provide theoretical basis for the rational fertiliza-tion for E.koreanum.the D-saturation optimal design was adopted to establish a regression model be-tween the yield of E.koreanum leaves and the application of N,P and K.The effects of N,P dand K application on the yield leaves and icariin and total flavonoids of Epimedium koreanum were studied in combination with frequency distribution of factors.The contribution of phosphorus fertilizer to the yield was the largest in the flowering stage and the early fruit stage;The contribution of nitrogen fer-tilizer was the largest in the ripening stage;The contribution of potassium fertilizer was the largest in the green leaf stage.The results of the frequency analysis showed that the optimal fertilizer applica-tion of N,P2O5 and K2O were 12.89-17.30 kg/667m2,16.45-19.90 kg/667m2 and 17.24-20.82 kg/667m2 for the target leaves yield over 1 g per plant and confidence interval of 95％,respectively.Those were 6.46-15.80 kg/667m2,8.88-17.26 kg/667m2 and 9.35-19.25 kg/667m2 for the icariin content over 1％and confidence interval of 95％,and 12.83-18.57 kg/667m2,12.85-18.32 kg/667m2 and 16.78-21.01 kg/667m2 for the total flavonoid content over 20％and confidence interval of 95％,respectively.Reasonable application of N,P and K can not only improve leaf yield,but also play an important role in ensuring the quality of E.koreanum.Comprehensively taking into account the ef-fects of N,P and K application on the yield and quality of E.koreanum,we can conclude that the op-timal fertilization rates for high-quality production of E.koreanum are N 12.89-15.80 kg/667m2,P2O516.45-17.26 kg/667m2,and K2O 17.24-19.25 kg/667m2,respectively,and the optimal fertilization ratio of N∶P2O5∶K2O is 1∶(1.04-1.34)∶(1.34-1.49).
