Although about 80% of the nitrogen in the air can not be directly used by ordinary plants, peanuts,but soybeans, alfalfa and other leguminous plants can only convert the molecular nitrogen in the air into ammonia nitrogen that can be used by plants through symbiotic nitrogen fixation with rhizobia. After the seeds germinate and take root, rhizobia invade the roots from the root hairs. Under certain conditions, they form nodules with nitrogen fixing ability. Under the action of nitrogen fixing enzymes, the bacteroids in the nodules convert molecular nitrogen into ammonia nitrogen. At the same time, each nodule is a miniature nitrogen fertilizer plant, which continuously delivers nitrogen to plants for utilization...
