The invention relates to a modified diatomite microecological preparation and a preparation method thereof. The microecological preparation is prepared from the following raw materials in parts by weight: 15-25 parts of
lactic acid bacteria, 9-14 parts of candida utilis, 9-13 parts of
bacillus subtilis, 10-16 parts of
enterococcus faecalis, 45-55 parts of diatomite, 9-13 parts of fructo-
oligosaccharide, 8-13 parts of
aspergillus niger, 5-8 parts of
aspergillus oryzae, 5-9 parts of
lactobacillus acidophilus, 20-25 parts of bifidobacteria, 5-10 parts of
bacillus licheniformis, 0.5-2 parts of bean dregs, 5-10ml of
acetic acid, 5-10 parts of FeCl3, and an appropriate amount of water. The
lactic acid bacteria, the candida utilis, the
bacillus subtilis and the
enterococcus faecalis which are screened out are all adapted to grow under meta-acid environment, have strong resistance to animal
intestinal mucosa and
strong field planting capacity, and are high in reproductive performance; and through optimized arrangement of species, synergistic
efficacy is sufficiently exerted, the
decomposition of
protein, fat and
cellulose by
metabolism products is strengthened, and the pH value in the animal intestines can be reduced by produced
lactic acid and other organic acids, so that growth and propagation of other microorganisms are restrained, and the microecological preparation has a certain bacterial function.
