The invention relates to an agricultural fertilizer, in particular to a microbial compound fertilizer and application thereof. The microbial compound fertilizer specifically consists of a zymophyte agent and a compound fertilizer, wherein each gram of the compound fertilizer comprises not less than 0.2*108 bacterial cells; the compound fertilizer comprises the following components in percentage by weight: 5 to 15 percent of farmyard manure, 10 to 30 percent of humic acid, 5 to 8 percent of grass carbonic acid, 15 to 30 percent of nutrient and the balance of boric sludge; and the zymophyte agent is obtained by fermenting silicate bacteria, azotobacter chroococcum, actinomycetes, saccharomyces cerevisiae and rhodopseudomonas sphaeroides, wherein the silicate bacteria, the azotobacter chroococcum, the actinomycetes, the saccharomyces cerevisiae and the rhodopseudomonas sphaeroides are mixed together in a weight fraction of 1:1:1:1:1. The microbial compound fertilizer acting on a big field can increase the yield of crops by 20 to 30 percent, and simultaneously can obviously increase the percentage of fertile fruits, reduce fruit dropping and overgrow the fruits; besides, the maturation stage is shortened by 5 to 7 days, the yield-increasing effect is obvious, and simultaneously, the microbial compound fertilizer can obviously improve the appearance, the mouthfeel, the color and luster and the like of products, improve the quality by 1 to 2 grades, and prolong the product freshness date.

The invention discloses a biological preparation formula for purifying eutrophic a water body and a use method of the biological preparation formula. The biological preparation formula comprises the following raw materials in parts by weight: 15-40 parts of photosynthetic bacteria, 20-40 parts of denitrifying bacteria, 18-35 parts of acinetobacter, 8-24 parts of bacillus, 5-20 parts of bdellovibro and 9-23 parts of phosphorus-accumulating bacteria. The use method comprises the following steps: adding water the addition of which is 20 times weight of the raw materials, spraying 180g-280g of the solution to each cubic meter of the water surface of the to-be-processed water body by virtue of a high pressure sprayer, and simultaneously oxygenating the water body by virtue of an aerator; after repeatedly spraying for 5-15 days, carrying out reduced spraying; after 40-60 days, putting aquatic plants and aquatic animals into the water body. By using multiple microorganisms together, the micro ecological system of the water body is improved, the biodiversity of the water body is recovered, and the self-purification capacity of the water body is improved; the use method is easy, feasible and remarkably in effect, and the secondary pollution is avoided.
