摘　　要：以大豆为原材料,通过盆栽试验,设置单接菌根真菌、单接大豆根瘤菌和同时接种菌根真菌和大豆根瘤菌处理,以都不接为对照。研究不同接种对植株株高、茎粗、根长、结瘤数量等的影响。结果表明,土壤灭菌的发芽率高于未灭菌的发芽率。大豆根瘤菌的每盆中大豆苗的株数最多,所结根瘤数量最多,说明大豆根瘤菌能够促进大豆苗的生长,菌根真菌与大豆根瘤菌混合处理植株茎粗最高,所结的根瘤单个重量为0.007 g,添加菌根真菌的处理,植株叶片的叶绿素含量及氮含量最低,大豆的发芽率最低,但单株所结根瘤数最多,说明菌根真菌与大豆根瘤菌混合施用可以促进根瘤的形成和发育。Using soybeans as raw materials,pot experiments were conducted to set up treatments with single inoculation of mycorrhizal fungi,single inoculation of soybean rhizobia,and simultaneous inoculation of mycorrhizal fungi and soybean rhizobia,with no inoculation as the control.The effects of different vaccinations on plant height,stem thickness,root length,and nodule number were studied.The results showed that the germination rate of sterilized soil was higher than that of unsterilized soil.The number of soybean seedlings and the number of nodules formed by soybean rhizobia were the highest in each pot,indicating that soybean rhizobia could promote the growth of soybean seedlings.The mixed treatment of mycorrhizal fungi and soybean rhizobia had the highest stem thickness and a single nodule weight of 0.007 g.The treatment with added mycorrhizal fungi had the lowest chlorophyll and nitrogen content in plant leaves and the lowest germination rate of soybeans,but the number of nodules formed by a single plant was the highest,indicating that the mixed application of mycorrhizal fungi and soybean rhizobia could promote the formation and development of nodules.
