Efficient yield-increasing biological bacterial fertilizer

The invention discloses efficient yield-increasing biological bacterial fertilizer. The formula of the efficient yield-increasing biological bacterial fertilizer consists of the following raw materials in parts by weight: 30 to 40 parts of organic matter, 30 to 40 parts of cultivating soil, 10 to 12 parts of pure water mixture, 4 to 6 parts of actinomycetes, 3 to 5 parts of nitrogen-fixing bacteria, 6 to 8 parts of silicate bacteria, 2 to 3 parts of bacillus subtilis, 3 to 5 parts of paenibacillus polymyxa, 5 to 7 parts of trichoderma viride, 5 to 7 parts of saccharomycetes and 1 to 3 parts of photosynthetic bacteria. Fermentation is conducted on the basis of the traditional organic fertilizer to form the organic matters, neutralized buffering is conducted through high-quality black soil, the organic matters are dispersed into the black soil, chemical fertilizer is added into the pure water mixture, the action effect of the fertilizer is improved by the high-fertility effect of the low-concentration chemical fertilizer, the fertility of the bacterial fertilizer can be guaranteed, the passivated nutritional components in the soil can be released through the decomposition action of the microbial bacteria and then are completely utilized by crops, and the yield increasing effect is achieved; furthermore, nitrogen fixation is conducted by utilizing the absorption and dissimilation effect of the microorganisms well, so the soil fertility is improved and remained.
