摘　　要：以蝴蝶兰组培苗为试材,研究了炭基肥和椰糠、水苔以不同比例混合对移栽前基质理化性质和移栽后基质理化性质、蝴蝶兰组培苗的生长特性的影响,以期为蝴蝶兰的栽培提供参考依据。结果表明:在椰糠和水苔中加入炭基肥,显著改变了基质的理化性质,提高了有机质、全氮、全磷和全钾含量。蝴蝶兰成活率提高了3.71%~10.18%,叶宽增加7.74%~25.54%,叶绿素含量和净光合速率显著提高。其中,椰糠和炭基肥以4∶1生长状况最好,水苔和炭基肥以6∶1生长状况最好,说明炭基肥在蝴蝶兰组培苗基质中的应用有显著效果。Taking Phalaenopsis tissue culture seedlings as experimental materials,the effects of mixing carbon-based fertilizer,coconut bran and sphagnum moss in different proportions on the physical and chemical properties of the substrate before transplanting and after transplanting,and the growth characteristics of the Phalaenopsis tissue culture seedling were studied,in order to provide theoretical reference for the cultivation of Phalaenopsis.The results showed that adding carbon-based fertilizer to coconut bran and sphagnum moss significantly changed the physical and chemical properties of the substrate and increased the organic matter,total nitrogen,total phosphorus and total potassium content.The survival rate of Phalaenopsis increased by 3.71%-10.18%,the leaf width increased by7.74%-25.54%,and the chlorophyll content and net photosynthetic rate increased significantly.Among them,coconut bran and charcoal-based fertilizer had the best growth condition at 4∶1,and sphagnum moss and charcoal-based fertilizer had the best growth condition at 6∶1,indicating that the application of carbon-based fertilizer in the substrate of Phalaenopsis tissue culture seedlings has a significant effect.
