TECHNOLOGY FOCUS - AGRICULTURE - Preferred Component: The yeast is prepared by growing culture seed at 26 degrees C for 30 hours, mixing culture seed and yeast, inoculating in culture medium, culturing at 26 degrees C for 48 hours, adding protecting agent and attached type agent, and drying at 25 degrees C for 2 hours. Lactic acid bacteria is prepared by inoculating to de Man Rogosa Sharpe (MRS) culture medium and strain carrying out anaerobic culture process at 36 degrees C. Cellulose decomposing bacteria is prepared by taking 150 g cow manure, putting into 1000 mL beaker, adding 400 mL water, stirring for 30 minutes, taking filter slag to obtain cattle manure culture medium, taking 40 g cattle manure, sieving, taking 20 g, putting into 1000 mL beaker, adding 50 mL water, stirring for 30 minutes to obtain shake flask culture inoculant, taking 10 mL shake flask culture inoculant, adding 100 mL cattle manure culture medium, stirring at rate of 120 revolutions/minute, culturing at 45 degrees C for 3-5 days, mixing 200 g/L potato extracts, 20 g/L glucose and 17-20 g/L agar, dissolving to 1 L to obtain potato dextrose agar, inoculating Phanerochaete chrysosporium, Trichoderma, Rhizopus, Aspergillus, Panaeolus and Coprinus at volume ratio of 2:1:1:1:1:1 to potato dextrose agar, and drying. Azobacter is prepared by mixing 0.5-2.5 g/L sodium chloride and 0.05-0.5 g/L ammonium sulfate, and inoculating. Photosynthetic bacteria is prepared by taking culture shrimp seedling, mixing 1 g ammonia chloride, 0.5 g dipotassium hydrogen phosphate, 0.2 g magnesium chloride, 2 g sodium chloride and 0.1 g yeast extract adding 900 mL water, sterilizing for 20 minutes, filtering, adding 5 g/50 mL aqueous sodium bicarbonate solution and 50 mL ethanol, filtering, adjusting pH to 7 with 0.1 N phosphoric acid, adding 2.5 kG strain liquid, shaking, standing in direct sun heat, and aging. The azobacter has optimum temperature for growth and nitrogen fixation at 26-37 degrees C. ACTIVITY - Fertilizer.
