摘　　要：棕色固氮菌分离鉴定与初步应用研究结果表明,通过分离培养和鉴定,分离出的6个棕色固氮菌贵州地方株,其中4株有一定固氮能力,另外2株固氮能力较强。应用棕色固氮菌制成菌肥,可以显著提高黑麦草产量。Isolation and identification and primary application of Azotobacter vinelandii were studied.The results showed that through isolation,culture and identification,6 strains of Azotobacter vinelandii were obtained.Among them,four strains had certain nitrogen fixation ability,and other two strains were even better.Using Azotobacter vinelandii,the bacterial fertilizer was made,and it significantly increased the yield of ryegrass.
