豆科植物根部自幼苗开始就感染了形成根瘤的根瘤细菌,这些细菌利用植物光合作用产物——碳水化合物作能源,依靠本身固氮能力,将空气中游离态氮转化成化合态氮提供给植物。这种转化过程人们称它为生物固氮。据估计每年通过微生物的作用转化成氮肥约1.75亿吨,占全世界氮肥供应的70％。这个转化过程可在常温常压下进行,而用化学方法生产氮肥,每生产1公斤氮肥要耗费1.5立方米的天然气,还污染环境给人类带来了危害。故接种花生根瘤菌不仅节约能源,节省化肥,降低成本,而且不污染环
The roots of legumes are infected with nodulated nodulated bacteria from the start of their seedlings. These bacteria utilize the photosynthetic product of carbohydrates as a source of energy and rely on their nitrogen fixation capacity to convert the free nitrogen in the air to nitrogen. This conversion process people call it biological nitrogen fixation. It is estimated that about 175 million tons of nitrogen fertilizers are converted into nitrogenous fertilizers each year, accounting for 70% of the world’s nitrogenous fertilizer supply. This conversion process can be carried out at room temperature and pressure, and the chemical production of nitrogen fertilizer, producing 1 kg of nitrogen fertilizer to consume 1.5 cubic meters of natural gas, but also polluting the environment has brought harm to humans. Therefore, inoculation of peanut rhizobia not only save energy, save fertilizer, reduce costs, and does not pollute the ring
