小麦根系联合固氮菌剂用于生产河北省科学院微生物研究所从小麦根系分离、筛选出了三个活性较强的固氮菌株(属细菌类,不生根瘤),配制成小麦根际联合固氮菌剂,经过小区严格试验,一九八四年省科委将“小麦根际联合固氮”开发研究课题列入省科技发展计划,在25个 Wheat root combined with nitrogen-fixing bacteria used in the production of Hebei Academy of Sciences Institute of Microbiology isolated from wheat roots, screened three strong nitrogen-fixing strains (bacteria, not root nodules), formulated as wheat rhizosphere nitrogen fixation agent After a rigorous test of the plot, in 1984, the provincial Science and Technology Commission included the research project of “Nitrogen fixation in wheat rhizosphere” into the provincial science and technology development plan.
