真菌与人类的关系十分密切,在工业、农业、医药、食用等方面已被广泛应用。人们对真菌的利用正日益扩大。其中有一些真菌能和高等植物的根生长在一起,形成菌根,帮助植物吸收水分和养料,有利于植物的生长发育。二十世纪初,许多人发现豆包菌和树木一起生长时能形成外生菌根(ectotroph),它可以和松属 Pinus、黄杉属 Pseudotsuga、冷杉属 Abies、桦木属 Bltula、桉属 Eucal-ypt、栎属 Quercus、山核桃属 Carya 等共生。据报导松属 Pinus 中有34个种可以和豆包菌共生(Marx 1977)。通过人工培养可以形成菌根(Marx 和 Bryan 1971)。科学家 Fungi and human relations are very close, in industry, agriculture, medicine, food and other aspects have been widely used. The use of fungi is growing. Some of these fungi can grow together with the roots of higher plants to form mycorrhizae, helping plants to absorb moisture and nutrients, which are good for plant growth and development. At the beginning of the twentieth century, many people discovered that legumes formed ectotrophs when they grew with the trees and could interact with Pinus, Pseudotsuga, Abies, Bltula, Eucal-ypt , Quercus Quercus, Carya Hickory and other symbiotic. 34 species of Pinus Pinus have been reported as symbiotic with bean pest (Marx 1977). Mycorrhiza can be formed by artificial cultivation (Marx and Bryan 1971). the scientist
