Effect of Collaboration Between Soybean Rhizobia and Mycorrhizal Fungi on the Growth of Soybean Potted Plants
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 con-trol. 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.
