Beneficial bacterium fermented fertilizer capable of increasing soil breathability and preparation method thereof

The invention discloses a beneficial bacterium fermented fertilizer capable of increasing the soil breathability and a preparation method thereof. The fertilizer is composed of the following raw materials in parts by weight: 65 to 80 parts of edible fungus waste materials, 5 to 10 parts of EM inoculant, 45 to 70 parts of crop straw, 20 to 30 parts of brown sugar dregs, 4 to 8 parts of meerschaum powder, 10 to 15 parts of peanut shell, 15 to 25 parts of urea, 16 to 20 parts of ammonium chloride, 18 to 25 parts of potassium sulfate, 12 to 18 parts of calcium magnesium phosphor fertilizer, 5 to 9 parts of zinc sulfate, 4 to 5 parts of binder, and a proper amount of water. The edible fungus waste materials, which contain a plurality of organic substances such as residual edible fungus sporocarp, utilized organic nutrients, decomposed organic substances, and the like, are applied to embedding and enlarged cultivation of beneficial bacterium strains so as to improve the stress resistance and number of bacterium strains.
