氮是生命的元素,从巍然耸立的参天大树,到肉眼难见的微小生物;从翱翔蓝天的鸟儿,到畅游碧海的鱼群……都离不开氮素。特别是在农业生产中,氮素更起着举足轻重的作用,是世界粮食生产的直接限制因子。目前,全球每年生产的化学氮肥约为0.5亿吨,而自然生物固定的氮素竟达1.5亿吨,为化学固氮的3倍!生物固氮以其固氮量大、不污染环境、节省能源等特点,而成为一代代科学工作者梦寐以求的研究目标。
Nitrogen is an element of life, from towering towering trees to microscopic creatures that are not visible to the naked eye. Birds flying from the blue sky to the fish that swim in the blue sea ... can not do without nitrogen. Nitrogen, in particular, plays a decisive role in agricultural production and is a direct limiting factor in world food production. At present, the global annual production of chemical nitrogen fertilizer is about 050 million tons, while the natural biological fixation of nitrogen reached as high as 150 million tons, 3 times of chemical nitrogen fixation! Biological nitrogen fixation with its nitrogen-fixing capacity, does not pollute the environment, save energy , Has become the dream of scientific research scientists from generation to generation.
