Biological organic fertilizer with effect of controlling soil-borne diseases and preparation method of biological organic fertilizer

The invention discloses a biological organic fertilizer with an effect of controlling soil-borne diseases and a preparation method of the biological organic fertilizer. The biological organic fertilizer is prepared from the following raw materials in parts by weight: 100-160 parts of excrements of livestock, 60-80 parts of straws, 20-30 parts of wormcast, 0.4-0.6 part of a compound microorganism bacterium agent, 0.1-0.3 part of a fermentation accelerator and 3-5 parts of pururan. According to the biological organic fertilizer with the effect of controlling soil-borne diseases, disclosed by theinvention, on one hand, the soil fertility can be improved, and formation of a granular structure of the soil is facilitated, so that soil properties are improved, the activities of defense enzymes are improved, supply of moisture and nutrients of a relative overground part, cytokinin and other active materials is ensured, enhancement of normal activity of the overground part of plants is promoted, the crop yield is obvi
