Embodiment 1
[0025] A kind of production method of biological protein feed, its specific operation steps are:
[0026] Step 1. Pass the corn stalks through a straw grinder to crush them into particles that can pass through a 20-mesh sieve, and set aside;
[0027] Step 2: Treat the crushed straw particles with hot and humid steam for 30 minutes in an orbital autoclave at a temperature of 100° C., and set aside;
[0028] Step 3. According to the mass ratio of water and straw granules treated with hot and humid steam as 1:1, add water to the straw granules that have been treated with hot and humid steam, and mix well to obtain mixture A; then inoculate and expand the culture in the obtained mixture A The final brown rot fungus, the inoculum amount is 1% of the mixture mass; then, at a temperature of 30°C, ferment for 2 days to obtain a one-step fermentation product, which is set aside;
[0029] Step 4. Add urea, magnesium sulfate and potassium dihydrogen phosphate to the obtained one-step fe...
