Isolation and Screening of Effective and Affinity Strains of Growth-Promoting Bacteria from Cotton Rhizosphere
棉花根际亲和性高效促生细菌的分离筛选

To screen effective and affinity plant growth-promoting rhizobacteria strains(PGPR) that can react with cotton lectin from cotton rhizosphere,we isolate nitrogen-fixation bacteria,phosphate-releasing bacteria and potassium-releasing bacteria from cotton rhizosphere by Ashby medium,phosphate-releasing bacteria medium and potassium-releasing bacteria medium,respectively.The strains were re-screened by cotton lectin labeled with fluorescein isothiocyanate.According to their ability of nitrogen-fixation,p-relea...
