摘要
氮素供应不足是我国豆科作物生产上普遍存在的问题,但是,依靠化学肥料解决大面积土壤缺氮问题是不现实的,也是不经济的。文章介绍了生物固氮为植物提供氮源的方法,并对不同环境因素对根瘤共生固氮系统的影响作了初步探讨。
Nitrogen supply shortage in legume crop production on the universal existence question, but rely on chemical fertilizer to solve the problem of large area soil nitrogen is not realistic, but also economic. This paper introduces the biological nitrogen fixation is a plant available nitrogen source method, and the influence of different factors on Rhizobium symbiotic nitrogen fixation system were studied.
