摘　　要：试验开展了不同肥料及生长调节剂处理对口红花栽培生长影响的研究,结果发现:在以N-P-K为20-20-20基础施肥的前提下,在叶面喷施一定的磷、钾、钙肥及矮壮素有利于口红花多生分枝生长;增施镁肥有利于口红花形成良好的叶色;增施P肥、微量元素及矮壮素有利于较快成花。而口红花叶面如施用过多的Ca(NO3)2或尿素等N肥,易发生叶色较淡,节间较长,花期推迟等现象。Different application of fertilizer and plant growth regulator were studied on Aeschynanthus lobbianus＇ cultivation and florescence regulation. Results suggested that the foliar fertilizers of P, K, Ca and chlormequat at 200 g/L spraying on leaves were useful fbr more branches. The foliar fertilizer of Mg was useful for better standard of leaf colors. The foliar fertilizers of P, trace elements and chlormequat at 200 g/L were useful for early flowering. Too much of Ca （NO3）2 and CO（NH2）2 fertilization were not favor for good standards of the leaf color and panel length , and it delayed flowering either.
