摘　　要：试验以老港垃圾填埋场封场土为栽培介质和盆栽红叶石楠为研究材料,分别施入AM菌根制剂、微生物菌剂,通过对红叶石楠的叶片性状、光合效率和生长量的监测,研究不同微生物菌肥对垃圾封场土中植物生长的影响。结果表明,菌肥提高了红叶石楠叶片的叶面积和干物质含量,降低了叶片的比叶面积,同时提高了红叶石楠叶片的净光合速率,降低了气孔导度和蒸腾速率,促进了红叶石楠地径、株高和新梢的生长量增加。在不同菌肥处理中,菌根制剂的正向效应最突出。微生物菌肥,尤其是菌根制剂,能够促进垃圾填埋场封场土中的植物生长,具有推广使用的潜力。The pot cultured seedlings of Photinia fraseri planted in the cover soil of the waste landfill were inoculated with arbuscular mycorrhizal （AM） inoculum, microbial inoculants and a mixture of both. The effects of the different kinds of microbial fertilizers on the seedling growth were studied by measuring the indexes of height, leaf area, and photosynthetic efficiency. The results showed that the microbial fertiliz- ers improved the growth of the seedlings compared to the control. The net photosynthetic efficiency of the inoculated plants increased. Among the inoculated plants, AM inoculum inoculated seedlings grew best. It was concluded that the microbial fertilizer, especially AM inoculum, could promote the growth of the plants, which would have application potential in vegetation restoration and reconstruction in waste land- fill.
