NOVELTY - Preparation of microbial fertilizer involves inoculating Streptomyces microflavus in inclined plane culture medium comprising sucrose, dipotassium phosphate, magnesium sulfate, agar and water; culturing at 28-32 degrees C for 72-120 hours; washing inclined plane culture with sterile water; preparing solid seed culture medium consisting of cultivating soil, calcium carbonate and water; uniformly stirring; culturing for 72-120 hours; drying and crushing seed containing microorganism; adjusting moisture content of seed culture; and connecting crushed seed powder to cultivating soil.    USE - Preparation of microbial fertilizer used for cultivating Solanum lycopersicum (claimed), i.e. tomato.    ADVANTAGE - The method prepares microbial fertilizer with low production cost, simple manufacturing technique, high active component, and good application effect on tomato.    DETAILED DESCRIPTION - Preparation of microbial fertilizer comprises inoculating Streptomyces microflavus (CICCM 23627) in inclined plane culture medium comprising sucrose, dipotassium phosphate, magnesium sulfate, agar and water; culturing at 28-32 degrees C for 72-120 hours; washing inclined plane culture with sterile water; preparing solid seed culture medium consisting of cultivating soil, calcium carbonate and water; uniformly stirring; culturing for 72-120 hours; drying and crushing seed containing microorganism; adjusting moisture content of seed culture; connecting crushed seed powder to cultivating soil containing 700-850 g cottonseed, 50-100 g rice powder, 50-100 g calcium carbonate, and 50-100 g culture medium; uniformly stirring; using open pan method to culture and culture medium thickness of 3-5 cm; culturing at 28-32 degrees C for 96-120 hours to obtain while culture material; drying culture material; crushing; packaging to obtain microorganism fertilizer, in which all culture mediums require high-temperature and high-pressure sterilization.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a process for preparing microbial fertilizer (Drawing includes non-English language text).
