Research on mechanism and ecological effects of mycorrhizal inoculation in different density soil
The soil in mine reclamation area,which degree of compaction was significantly higher than normal soil as a result of the layering cover and laminate engineering method,was not conducive to the growth of plants.Under laboratory conditions,three kinds of soil compaction density levels were simulated and arbuscular mycorrhizal fungi was selected to research the effect and mechanism of action of mycorrhizal fungi inoculation to the growth of plants in different soil compaction.The results indicate that,by the Glomus mosseae mycorrhizal inoculation,the affinity degree between mycorrhizal and plants was high,and the length of hyphae was increased significantly,and the activities space and scope of plant roots was expanded and the resistance and growth condition of plants was improved.The ability of the absorption N,P,K from the soil of plants and the growth of plants was raised significantly; The desirability of the plant to grow in the 1.65 g/cm3 density levels soil was enhanced to 1.35 g/cm3 density levels.
