小麦根际联合固氮菌剂是河北省科学院微生物研究所利用从小麦根系中分离出的联合固氮菌,采用独特的培养基配方,经工业发酵制成的新型生物增产菌剂。它具有固定大气中分子态氮和产生多种活性物质的机能,为植物提供氮素营养和促进生长。已在全国近20个省示范推广,该项成果1988年获国家发明奖,并被列入《1989～1991年国家科技成果重点推广计划》。我省系全国17省市(区)小麦根际联合固氮菌开发协作组成员,从1988年起开展了该项目的试验示范工作,初步摸索出该技术在我省的应用效果及关键技术。
The rhizosphere combined nitrogen-fixing bacteria agent of wheat is a new biological growth-promoting bacterium made by industrial fermentation using the unique nitrogen-fixing bacteria isolated from wheat roots by the Institute of Microbiology, Hebei Academy of Sciences. It has the function of fixing molecular nitrogen and producing many active substances in the atmosphere, providing nitrogen nutrition and promoting growth for plants. It has been demonstrated and popularized in nearly 20 provinces across the country. This achievement won the national invention award in 1988 and was listed in the “Key National Plan of Science and Technology Promotion Plan 1989-1991”. The province is a member of the Collaboration team for the development of rhizosphere and azotobacter in wheat in 17 provinces (autonomous regions) across the country. Since 1988, pilot projects have been carried out in this project. The application effect and key technologies of this technology in our province have been tentatively explored.
