分别以可溶性淀粉、鼠李糖、蔗糖为唯一碳源的无氮培养基,从校园土壤中分离到褐球固氮菌(Azotobacter chroococcum)、维涅兰得固氮菌(A. vinelandii)和拜氏固氮菌(A. beijerinckii)三种菌种各2株菌株.将3种菌种单独及混合分别投加到菜场垃圾堆肥装置中.结果表明,接种混合固氮菌的菜场垃圾废物堆肥的全氮、铵态氮、硝态氮的含量最高,堆肥化所用的时间最短.接种一种固氮菌(褐球固氮菌、拜氏固氮菌或维涅兰得固氮菌)的也有所提高.

Using three kinds no-nitrogen media with soluble starch, sucrose or rhamnose as sole carbon source. 2 strains of Azotobacter chroococcum, A. beijerinckii and A. vinelandii were isolated from the soil of the University. Adding the 3 kinds Azotobacter and their mixture to the device of the garbage composting. The concentrations of TN, NH4+-N and NO3--N in each group were measured every 3 day. The status of composting were observed. The result showed that the concentrations of TN, NH4+-N and NO3--N in the composting device inoculated with the mixture was the most than others. The period of the composting was the shortest. The following was Azotobacter chroococcum, A. vinelandii and A. bei-jerinckii in turn. Composting inoculated with nitrogen-fixing organisms could raise the quality of compost and shorten the cycle of composting.
