Embodiment 1
[0030] A kind of preparation method of biological zinc preparation, concrete steps comprise:
[0031] (1) Cultivation of primary strains
[0032] Preparation of primary strain medium: 0.3g industrial sodium lactate, 0.2g anhydrous sodium acetate, 0.2g ammonium sulfate, 0.3g anhydrous zinc sulfate, 0.2g peptone, 0.3g yeast powder, 98.5g tap water, mix and dissolve ,spare;
[0033] Put the primary strain medium into the triangular culture bottle, seal it, put it into a medical pressure sterilizer for steam sterilization, take out the sterilized primary strain medium, cool it down to 28°C naturally, add 3 mL of photosynthetic bacteria , sealed, and then placed in an incubator with an incandescent lamp at a temperature of 28°C and cultivated for 70 hours to obtain a first-grade bacterial strain for future use;
[0034] (2) Cultivation of secondary strains
