NOVELTY - Bio-organic fertilizer composition production involves using raw materials, which comprises (in wt.%): lees (20-22), corn straw (15), weed (9), ficus tikoua (5), peanut shell (15), sawdust (3), starch (5), mildew feed (5), organic manure fermentation agent (1), chicken duck excrement (18-20), deodorant (1), biological nitrogen-fixing bacteria (0.1), cellulolytic bacteria (0.2), organic phosphorus decomposing bacteria (0.2), ammoniated bacteria (0.1), solubilizing bacteria (0.1), potassium bacteria solution (0.1) and phosphonate activator (0.2).    USE - Method for producing bio-organic fertilizer composition (claimed) used for promoting growth of crops.    ADVANTAGE - The method enables to produce bio-organic fertilizer composition, ensured reduced the disease index of cropping.    DETAILED DESCRIPTION - Bio-organic fertilizer composition production involves using raw materials, which comprises (in wt.%): lees (20-22), corn straw (15), weed (9), ficus tikoua (5), peanut shell (15), sawdust (3), starch (5), mildew feed (5), organic manure fermentation agent (1), chicken duck excrement (18-20), deodorant (1), biological nitrogen-fixing bacteria (0.1), cellulolytic bacteria (0.2), organic phosphorus decomposing bacteria (0.2), ammoniated bacteria (0.1), solubilizing bacteria (0.1), potassium bacteria solution (0.1) and phosphonate activator (0.2). The chicken duck excrement is kept into fermentation tank, and then biological nitrogen-fixing bacteria, cellulolytic bacteria, organic phosphorus decomposing bacteria, ammoniated bacteria, solubilizing bacteria, potassium bacteria solution and phosphonate activator are added to the tank. The obtained material is mixed uniformly , and then fermented them for 14-16 days. The deodorant is added to the obtained material, and then stored. Grain, corn straw, weed, ficus tikoua, peanut shell, sawdust, starch powder, mildew feed and organic fertilizer fermenting agent are crushed into powder, and then water is added to them. The obtained material is fermented for 16-18 days. The obtained material is dried, and then mixed them with the stored material. The obtained material is granulated, and then dried to obtain the finished product.
