　　为确定高质量韭菜幼苗的施肥方案，试验采用饱和D-最优试验设计，研究氮、磷、钾对设施韭菜幼苗质量的影响，并在此基础上，建立以韭菜幼苗质量得分为目标函数，氮、磷、钾编码值为自变量的数学模型。结果表明，合理的氮磷钾配施可以显著提高韭菜幼苗质量，其中钾肥对幼苗质量的影响大于磷肥、氮肥，且磷肥和钾肥之间交互作用显著。同时，通过对模型解析，确定在本研究条件下韭菜幼苗质量综合得分超过90分的施肥方案，即N施用量为205.65~304.95 kg/hm2、P2O5为164.10~225.00 kg/hm2、K2O为228.45~328.50 kg/hm2时，才有望获得高质量韭菜幼苗。

In order to achieve fertilization scheme of Chinese chives seedling with high quality, the effect of nitrogen, phosphorus and potassium on seedling was studied with design of saturated D-optimal regression. And the resulted obtained, a mathematical model was established, in which N and K applied were independent variables, integrated quality value of seedlings was dependent variables. The results showed that the seedling quality was significantly improved with reasonable usage and ratio of N, P and K. Meanwhile the effect of potassium was higher than phosphorus and nitrogen, the interaction of potassium and phosphorus was significant. When N was 205.65-304.95 kg/hm2, P2O5 was 164.10-225.00 kg/hm2, K2O was 228.45-328.50 kg/hm2 under this experimental condition, the fertilizer project with integrated quality value of seedlings over 90 was achieved.
