Selection of Arbuscular mycorrhizae and Rhizobium for Production of Biological Materials Used to Revegetation for The Campus Scene

Abstract

    Rhizobium and Arbuscular mycorrhizal (AM) fungi are capable of symbiosis with plant roots. They bring many benefits to plant hosts as to stimulate the growth and development of plants, increase drought tolerance and reduce disease incidence. This study was executed with the aim to isolate and select Arbuscular mycorrhizae and Rhizobium strains with a high symbiosis for biological material production to revegetation of the campus scence. Two strains of Arbuscular mycorrhizal fungi and three Rhizobium strains were selected that exhibit fast growth, high vitality and

symbiosis with plants and could be used for biological material production. The inoculation experiment with biological materials to the revegetation of grass proved the establishment of the symbiosis of Rhizobium and Arbuscular mycorrhizal fungi with host plants that promoted the plant growth and development and improved soil fertility. The vegetation covering rate using biomaterial treatment was very high (95.63%), 1.75 times higher than the control (54.6%) after 5 weeks of application.
