为寻求碧桃最佳施肥配比，，采用“311‐A”最优混合设计对南宁青秀山的观赏桃花碧桃进行N肥、P肥和K肥配比试验研究，并对试验数据进行统计分析，建立三元二次回归方程，进行仿真寻优。结果表明：最优施肥配比尿素90．43 g·株‐1，钙镁磷肥140 g·株‐1，氯化钾42 g·株‐1，每株平均产量为1038朵，每株肥料利润20．39元。碧桃最佳施肥配比为N∶P2 O5∶K2 O＝1∶0．125∶0．606。

In order to search the optimal fertilization recipe for Prunus persica L .,the fertilization experiment of nitrogen(N) ,phosphorus(P) and Potassium(K) of Prunus persica L .was studied by using“311‐A” optimal mixed design method in Nanning Qingxiu Mountain .Based on statistical calculation ,ternary quadratic regres‐sion model of fertilizing scheme was established to carry out emulation and optimization .The results showed that optimum fertilizer formula for Prunus persica L .was urea 90 .43 g per plant ,calcium magnesium phos‐phate 140 g per plant ,potassium chloride 42 g per plant ,the yield was 1 038 flowers per plant ,and fertilizer profits was 20 .39 yuan per plant .The optimal fertilization recipe was N∶P2O5∶K2O=1∶0 .125∶0 .606 .
