| 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N 3P1K3,即 N:P2O5:K2O=4.36:1:4.92.

| Abstract: | 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 N3P1K3,i.e.N:P2O5:K2O =4.36:1:4.92. |
