Granular biological organic fertilizer

The invention discloses granular biological organic fertilizer. The organic fertilizer is prepared from the following raw materials in parts by weight: 400-500 parts of a decomposed organic material,100-150 parts of inorganic fertilizer, 40-60 parts of inorganic clay, 20-40 parts of humic acid, 20-40 parts of porous starch, 20-40 parts of expanded feather meal, 10-20 parts of activated sludge, 5-10 parts of microbial powder and 1-3 parts of a coated binder. The total effective viable bacteria count in the microbial powder is greater than or equal to 0.2*10 cfu/g. The granular biological organic fertilizer can effectively fix functional bacteria on fertilizer particles, the survival rate is high, the functional bacteria is not easy to lose, after applied into soil, can rapidly and massively multiply, and thus gives full play to the fertilizer effect and improves the yield of crops. 本发明公开了一种颗粒生物有机肥，包括以下重量份的原料：腐熟有机物料400-500，无机肥料100-150，无机粘土40-60，腐殖酸20-40，多孔淀粉20-40，膨化羽毛粉20-40，活性污泥10-20，微生物菌粉5-10，包膜粘结剂1-3；所述微生物菌粉中
