摘　　要：该文阐述了氮、磷、钾三要素的不同浓度配比对大花蕙兰营养生长的影响。试验结果表明:N肥对大花蕙兰叶面积增量、假鳞茎的直径、叶片长度的影响达到极显著差异,对假鳞茎增量也达到显著差异;同时K肥对叶面积增量、叶片长度的影响达到极显著差异;但P肥对所有生长指标均未达到显著差异。最佳的N、P、K组合是N3P1K3,即N:P2O5:K2O=4.36:1:4.92。Effects of NPK nutrients on vegetative growth of Cymbidium hybridum were studied with an orthogonal experimental design. The results indicate： effect of N on increment of the leaf , the development of the pseudobulb and the length of leaf was the most significant. It was also significant on increment of the pseudobulb, effect of K on increment of the leaf, the length of leaf was the most significant. But All character of the plant growth performance showed effect of P was not significant. The optimum fertilization level of N, P, K was N3PIK3 ,i.e.N：P205：K20 =4.36：1：4.92.
