摘　　要：通过盆栽试验,研究了银合欢根瘤菌在新银合欢上的共生固氮效率。结果表明,在试验中所用的12个菌株都能显著地增加植株叶片的鲜重和含氮量,并能降低叶片中的含羞草素。其中尤以H87—4、H87—1和H87—2三个菌株最为明显。The efficiency of symbiotic nitrogen fixation of Leucaena rhizobia on Leucaena leucocephala cv. El Salvador was investigated through pot culture. The results indicated that all the 12 strains used in the experiment could effectively increase fresh weight and nitrogen content, while they decrease mimosine content in Leucaena leaves. Three of the rhizobium strains, H87—4, H87—2 and H87—1 were obviously superior to the others.
