Embodiment
[0020] A compound EM flora used for decontamination in aquaculture. The compound EM flora includes Lactobacillus acidophilus, Bacillus subtilis and Candida ovipositum.
[0021] Further, the ratio of strains to raw materials is: 90% corn bran + 10% compound EM bacterial liquid.
[0023] A kind of compound EM flora cultivation method for aquaculture decontamination, comprises the steps:
[0024] (1) Take lactic acid bacteria strains, Bacillus subtilis strains, and yeast strains respectively, and add liquid medium to the mixture of the above strains to obtain a composite bacteria liquid;
[0025] (2) The lactic acid bacteria solution obtained in the previous step is added to the brown sugar to proliferate, and the temperature and humidity are controlled;
[0026] (3) Add sodium silicate, water, brown sugar, wheat bran, and jade bran to the mixer and mix evenly, ferment with the compound ba...

Abstract
The invention discloses a preparation method of a composite EM flora for aquaculture decontamination. The composite EM flora comprises lactobacillus acidophilus, bacillus subtilis and candida oviposition. According to the invention, through screening, culturing and optimizing local dominant strains, including spores, yeast, lactobacillus, photosynthetic bacteria and other strains having the pollution reducing effect on aquaculture water, and through carrier compounding, the active activity of the strains is ensured, and the synergistic effect of the strains is exerted at the same time. The various water body toxins can be effectively degraded, macromolecular organic matters are decomposed, and toxic and harmful pollution sources are degraded, so that the breeding of harmful bacteria is inhibited, and various water body harmful indexes are reduced.
Description
technical field [0001] The invention relates to the field of preparation methods of composite EM flora, in particular to a preparation method of composite EM flora for aquaculture decontamination. Background technique [0002] In aquaculture (green shrimp, river shrimp, grass shrimp, prawn, prawn, base shrimp, pipa shrimp, lobster, crab, sea cucumber, frog, loach, eel, soft-shelled turtle, eel, sea freshwater fish) due to a large number of feeding The remaining bait, the accumulation of a large amount of excrement of aquatic animals in the water body, the increasing density of breeding in pursuit of income, the regular use of disinfectants and drug residues, etc. lead to a large load on the water body, and the physical and chemical indicators of the breeding water are destroyed—— The water quality deteriorates and becomes turbid, and the pond water turns green, black, red, and even bad and smelly. It leads to a large amount of harmful substances such as ammonia nitrogen and...
