NOVELTY - Biological special fertilizer comprises 10-30 wt.% composite microorganism microbial inoculum, 10-45 wt.% microorganism microbial inoculum, and 50-80 wt.% inorganic fertilizer. The composite microbial agent is produced by microorganisms and bacteria culture matrix composition. The microorganism is Bacillus licheniformis, Bacillus cereus, and/or Bacillus subtilis. The composite microbial agent comprises 80-90 wt.% organic powder, and 10-20 wt.% inorganic powder.    USE - Biological special fertilizer used for preventing and controlling peanut nematode disease (claimed), and promoting flower root.    ADVANTAGE - The fertilizer improves fertilizer effect.    DETAILED DESCRIPTION - Biological special fertilizer comprises 10-30 wt.% composite microorganism microbial inoculum, 10-45 wt.% microorganism microbial inoculum, and 50-80 wt.% inorganic fertilizer. The composite microbial agent is produced by microorganisms and bacteria culture matrix composition. The microorganism is Bacillus licheniformis, Bacillus cereus, and/or Bacillus subtilis. The composite microbial agent comprises 80-90 wt.% organic powder, and 10-20 wt.% inorganic powder. The organic powder is wheat bran, rice bran, soybean meal, corn cob powder, peanut shell powder, straw powder or cotton seed hull. The inorganic powder is adsorbent powder, urea and potassium dihydrogen phosphate. The adsorbent is zeolite, diatomaceous earth, vermiculite or attapulgite. The microorganism is Bacillus thuringiensis bacterium, Serratia stick, Beauveria bassiana or Metarhizium, dried to 10% moisture. The inorganic fertilizer comprises 200-450 pts. wt. urea, 200-400 pts. wt. potassium sulfate, 100-240 pts. wt. calcium magnesium phosphate, 50-250 pts. wt. monoammonium phosphate and 20-100 pts. wt. humic acid. An INDEPENDENT CLAIM is included for preparation of biological special fertilizer comprising taking prepared composite microorganism microbial inoculum, microorganism microbial inoculum and inorganic fertilizer, and stirring uniformly.
