It has been proved that azotobacter CN-2 has a higher activity of nitrogen fixation in pure slant culture. Inoculated to wheat seen, the azotobacter can live in the rhizosphere, which has a higher activity of nitrogen fixation and improves nitrogen supplement to plant. Weight and nitrogen content of dry wheat seeding have been increased.
