摘　　要：以降香黄檀(Dalbergia odorifera T.Chen)苗木为试验材料,采用无纺布育苗袋栽培对比试验,研究微生物菌肥对降香黄檀苗木生长及土壤酶活性的影响。结果表明,与对照相比,合理施用微生物菌肥可以促进降香黄檀生长,增强了抗性,强化了苗木各部分之间的协调性,提高了苗木质量,对根际土壤酶活性也有明显的正向作用。其中,微生物菌肥施用量2 g/株的效果最好。The seedling of Dalbergia odorifera was taken as the test material,and the comparison experiment was carried out by nonwoven bag cultivation.The effects of microbial fertilizer on the growth of Dalbergia odorifera seedlings and soil enzyme activity were studied.The results showed that,compared with CK,the application of fungus fertilizer could obviously promote the growth of Dalber⁃gia odorifera seedlings,enhance the resistance,strengthen the coordination among each part of the seedlings,improve the quality of the seedlings and increase the activity of rhizosphere soil enzymes.Among them,the application amount of microbial fertilizer 2 g per plant had the best effect.
