[0045] Example 1
[0046] Step (1) Dry the fresh rabbit manure with a belt hot air dryer at 150° C. to make the moisture content below 10%. After cooling, use a universal grinder to pulverize and pass a 100-mesh sieve to prepare rabbit manure powder for use;
[0047] Step (2) Weigh 100 kg of edible mushroom Pleurotus eryngii chaff, add 1000 kg of 40-50℃ hot water, soak for 60 minutes, heat and boil for 5 hours, and then squeeze with a wrap-type press to obtain squeezed liquid. Add 500 kg of hot water at 40-50℃, soak for 40 minutes, heat and boil and extract for 1.5 hours, and then press with a wrap-type press to obtain a squeezed liquid. Combine the two squeezed liquids; Other use
[0048] Step (3) Centrifuge the combined squeezed liquid obtained in step (2) with a horizontal centrifuge at a centrifugal speed of 12000r / min to obtain the supernatant and solid phase precipitate; the solid phase precipitate is used for other purposes;
[0049] Step (4) The supernatant obtained in step (...

[0056] Example 2
[0057] Step (1) Dry the fresh rabbit feces in a hot air drying box at 200°C to make the moisture content below 10%. After cooling, use a universal pulverizer to pulverize and pass a 100-mesh sieve to prepare rabbit feces powder for use;
[0058] Step (2) Weigh 100 kilograms of edible fungus Flammulina velutipes chaff, add 500 kilograms of hot water at 40-50°C, soak for 50 minutes, heat and boil for 4 hours, then squeeze with a wrap-type squeezer to obtain squeezed liquid, Then add 500 kg of hot water at 40-50℃, soak for 40 minutes, heat and boil for extraction for 3 hours, then squeeze with a wrap-type press to obtain squeezed liquid. Combine the two squeezed liquids; the mushroom dregs are used for other purposes ;
[0059] Step (3) Centrifuge the combined squeezed liquid obtained in step (2) with a horizontal centrifuge at a centrifugal speed of 8000r / min to obtain the supernatant and solid phase sediment; the solid phase sediment is used for other purposes;
