TECHNOLOGY FOCUS - AGRICULTURE - Preferred Method: The step (A) includes preparing brown azotobacter into 68 hundred million/ml of bacteria suspension. The step (B) includes taking (pts. wt.): taking solid farmyard manure (65), adding straw powder (25 ), weathered coal or grass carbon (5), calcium superphosphate (2.5) or monopotassium phosphate (2), water (1.5). The step (C) includes taking (pts. wt.): compost (92.5), sugar (1), sterilizing water (6), and bacterial suspension (0.4). The method further includes (D) preparing enrichment culture solution, (E) performing enrichment culture method, (F) preparing flat plate separated culture medium, (G) performing flat plate separation and culture, (H) enrichment culturing, and (I) fermenting. The step (D) includes providing (g): sugar (15), monopotassium phosphate (0.8), magnesium sulfate (0.2), sodium chloride (0.2), calcium carbonate (1), sodium molybdate (0.05), ferrous sulfate (0.1), peptone (5), water (1000 mL) (pH of 6.5-7). The step (E) includes taking enrichment soil (3-5 g) with 50 ml of water to obtain dirty solution, taking suspension and (5 mL) adding to 250 mL of triangular flask containing 30 mL of enrichment culture medium, culturing for 3-5 day at rate of 150 revolutions/minute at 25-30 degrees C. The step (F) includes adding 2% of agar to enrichment culture solution to flat plate separated culture medium, sterilizing and standing. The step (G) includes taking enrichment cultured culture medium, diluting for 10 times and coating on flat plate separated culture medium, and culturing for 2 days at 28 degrees C. The step (H) includes taking flat plate bacterial colony, transferring to enrichment culture medium, culturing for 2 days at 28 degrees C to obtain bacterial solution. The step (I) includes mixing enrichment culture solution with bacterial solution at ratio of 100:3-7, placing in fermentation tank, fermenting and culturing in shake bed at stirring rate of 200 revolutions/minute, culturing at 26-28 degrees C, culturing for 24 hours, culturing for 48 hours at tank temperature of 28-30 degrees C, tank pressure of 0.4-0.5 kg/cm3, stirring rate of 180 revolutions/minute, collecting fermentation liquid, regulating pH to 6.8-7.2, and uniformly stirring to obtain product.
