利用根瘤菌的固氮原理，使非豆科植物建立起象豆科植物一样的功能，实现氮素的部分自给，来减少对氮肥的依赖，培肥地力，增产增收，促进农业生态环境的良性循环，实现农业生产的可持续发展，是农业工作者不懈追求的目标。这方面的基础理论研究很多，也取得了很大的进展，早在 Utilizing the nitrogen fixation principle of Rhizobium, the non-leguminous plants can establish the same function as the leguminous plants and realize the partial self-sufficiency of nitrogen to reduce the dependence on nitrogenous fertilizer, fertilize the fertility, increase yield and promote the virtuous circle of agro-ecological environment To achieve the sustainable development of agricultural production is the unswerving pursuit of agricultural workers. There are many basic theoretical studies in this area and great progress has been made as early as the present
