据《安徽农林科学实验》报道,在无林地带育苗或在生荒秃岭造林,对苗木进行菌根土接种,是提高造林成活率和当年高生长的有效措施。菌根就是土壤中植物幼根上的白色丝状覆盖物,它是真菌与树木的须根形成的共生体。菌根的菌丝可以侵入树木根的细胞间隙,而留在根外的菌丝体则互相交织,把根包住,形成菌套。菌根的菌丝体可以伸展到离根很远的地方,形成稠密网状的‘辅助根’,这就扩大了树木根的吸收面,增强了根吸收水分和无机盐
According to “Anhui Agriculture and Forestry Science Experiment” reported that in non-forest zone nursery or alopecia arena afforestation, seedling mycorrhizal inoculation, is to improve the survival rate of afforestation and high growth of the effective measures. Mycorrhizal is a white, filamentous covering on plant roots in soil that is a symbiont of fungi and the fibrous roots of trees. Mycorrhizal mycelium can invade the interstices of the tree roots, while the mycelium left outside the root intertwined, the root package, the formation of bacteria sets. Mycorrhizal mycelium can be extended far away from the root to form a dense network of ’auxiliary root’, which expands the absorption surface of tree roots and enhances root absorption of water and inorganic salts
