摘　　要：针对切花芍药生长过程中盲目施肥的现状,以二年生芍药‘向天歌’为研究对象,采用“3414”试验施肥方案,结合隶属函数法,研究氮、磷、钾肥不同用量对切花芍药生长的影响,探讨切花芍药生产适宜的肥料用量。结果表明:不同施肥处理对芍药株高、茎粗、蕾径、分株数和切花数影响显著(P<0.05);氮、磷缺素区的综合隶属函数值小于无肥区,缺钾区大于无肥区,对芍药生长的影响为氮>磷>钾;N2P2K1处理的综合隶属函数值最大,为0.61,芍药植株生长最好;对各处理的综合隶属函数值和施肥量进行肥料效应函数拟合分析,一元二次、二元二次肥料效应函数方程拟合相关性均达显著水平,三元二次肥料效应方程为非典型模型,采用频率分析法计算肥料推荐量。综合分析各肥料效应函数方程的推荐用量及相应的综合隶属函数值,本试验切花芍药推荐施肥量为N 212.7 kg/hm^(2)、P_(2)O_(5)46.2 kg/hm^(2)、K_(2)O 49.9 kg/hm^(2),施肥配比为1∶0.21∶0.23,可用于本试验区切花芍药生产的施肥参考。In view of the current situation of blind fertilization in the growth process of cut herbaceous peony(Paeonia lactiflora Pall.),‘Xiangtiange’herbaceous peony was taken as the test material,the experimental fertilization scheme of“3414”was adopted,and the membership function method was used to study the effects of different amounts of nitrogen(N),phosphorus(P)and potassium(K)fertilizer on the growth of herbaceous peony,and the appropriate fertilizer amount for the production of cut herbaceous peony.The results showed that different fertilization treatments had significant effects on plant height,stem diameter,bud diameter,plant number and cut flower number(P<0.05).The comprehensive membership function value of N and P deficiency plots were less than that of no fertilizer plot,the K deficiency plot was greater than that of no fertilizer plot,and the effect on the growth of herbaceous peony was N>P>K.The comprehensive membership function value of N2P2K1 treatment was the largest,which was 0.61,and the growth of herbaceous peony plants was the best.The comprehensive membership function value and fertilizer application rate of each treatment were simulated and analyzed by fertilizer effect functions.The fitting correlation of quadratic and binary quadratic fertilizer effect function equations reached a significant level.The ternary quadratic fertilizer effect equation was an atypical model,and the frequency analysis method was used to calculate the recommended amount of fertilizer.Based on the comprehensive analysis of the recommended dosage of each fertilizer effect function equation and the corresponding comprehensive membership function value,the recommended fertilization amount of cut herbaceous peony in this experiment was N 212.7 kg/hm^(2),P_(2)O_(5)46.2 kg/hm^(2),K_(2)O 49.9 kg/hm^(2),and the fertilization ratio was 1∶0.21∶0.23.It could be used as a fertilization reference for the production of cut herbaceous peony in this experimental area.
