摘　　要：联合固氮是草原土壤氮素的重要来源,但是目前对于牧草联合固氮方面的研究却仍然比较滞后。综述了牧草联合固氮菌的种类、固氮酶活性、对牧草的促生作用、影响固氮的因素等方面的研究概况,以期能够引起人们对牧草联合固氮菌的重视。Associative nitrogen-fixing is an important source of nitrogen in grassland soils, but forages associative nitrogen-fixing bacteria research is backward. In order to draw attention to the forages associative nitrogen-fixing, the species of forages associative nitrogen-fixing bacteria, nitrogenase activity, growth-promoting effect for forage, factors that influence nitrogen-fixing, etc. were summarized.
