定位试验表明：施用耐氨固氮菌能促进水稻根系对氮素的吸收，显著增加水稻产量．耐氨固氮菌具有固氮能力，但按现行的施用量则固氮水平不足３０ｋｇ／ｈｍ２．在施氮水平较高的情况下。施用耐氨固氮菌能增加土壤有机质、全氮和碱解氮含量．
Positioning tests showed that the application of ammonia-resistant Azotobacter could promote the nitrogen uptake by rice roots and significantly increase the yield of rice. Ammonia-resistant azotobacter has nitrogen-fixing ability, but the current application rate of nitrogen fixation is less than 30kg / hm2. In the case of high nitrogen levels. Nitrogen-fixing Azotobacter can increase soil organic matter, total nitrogen and alkali-hydrolyzable nitrogen content.
