摘　　要：对三个乡土树种苗木进行微生物菌肥施肥试验,研究菌肥对不同树种苗木的生长、生物量和养分积累的影响。结果表明：菌肥可显著提高苗木的生长,苗高生长比对照提高了9.0%~14.5%;菌肥可极显著增加苗木生物量,尤其是施固氮溶磷肥处理比对照在地上部分干重、地下干重部分和全株干重分别增加了89.3%、50.2%和67.8%,效果极显著;施用菌肥极显著增加了苗木的N和P养分积累,尤其是施固氮溶磷肥在地上部分、地下部分和全株的N养分积累量方面分别比对照的极显著增加了85.0%、71.0%和78.8%,而P养分积累量分别比对照的极显著增加了75.5%、51.7%和63.5%。树种在苗高生长、生物量和养分积累方面对菌肥反应程度大小为香樟〉长芒杜英〉红锥。The fertilization trial of microorganism bacterial fertilizer on seedling stage of three indigenous tree species was conducted in order to study effects of bacteria fertilizer to growth,biomass and nutrient accumulation of seedling for three indigenous tree species.The trial results show that the bacterial fertilizer applied could high markedly increase the growth of seedling with a seedling height of 9.0% ~ 14.5% compared to the contrast（no bacterial fertilizer）.The bacterial fertilizer applied could high markedly increase the biomass of seedling,especially in nitrogen-fixing and phosphate-dissolving bacterial fertilizer,which the dry weights of over-ground,underground and whole plant could be increased 89.3%,50.2% and 67.8% respectively compared with the contrast.The bacterial fertilizer applied also could high markedly increase nutrient accumulation of nitrogen（N） and phosphors（P） for seedling,especially in nitrogen-fixing and phosphate-dissolving bacterial fertilizer applied,which the nutrient accumulations of over-ground,underground and whole plant could be increased 85.0%,71.0% and 78.8% for N accumulation,75.5%,51.7% and 63.5% for P accumulation,respectively compared with the contrast.The effects of bacterial fertilizer applied on height growth,biomass and nutrient accumulation rank from big to small as follows： Cinnamomum camphora,Elaeocarpus apiculatus and Castanopsis hystrix.
