摘　　要：与放线菌结瘤共生固氮的已知200多种非豆科植物,他们同时得到菌根菌的共生,所以,不仅有类似于豆科植物的高固氮力,而且固氮时间长,生长旺盛、迅速,抗逆性强,是许多不良生态环境改造的先锋树种。其树种与菌种作为资源研究利用,均会对人类生产、生活带来显著效益。More than 200 kinds of nonlegumes, known as symbiotic nitrogen fixation with actin-myces, were found to be simultaneously symbiosis with mycorrhizal fungi.Therefore, those nonlegumes have not only the high and long nitrogen fixation ability of legumes,but also the vigorous and rapid growth and strong stress resistance characters,and can be used as pioneer plants to improve adverse ecological environment.Great benefits will be achieved from the research and utilization of those nonlegumes and actinmyces.
