[0027] 1. Preparation of bacterial agents:
[0028] Select high-efficiency nitrogen-fixing bacteria liquids, phosphorus-solubilizing bacteria liquids, potassium-dissolving bacteria liquids, and double-acting actinomycete liquids with a bacterial count of 3.5×108 to 6.2×108 cells / ml, respectively, and measure them separately.
[0029] Mix according to the volume ratio (15-25): (25-35): (15-25): (20-30) to make a mixed microbial agent.
[0030] Add 50g-100g dextrin to every 1000mL of mixed bacterial agent to prepare the bacterial agent.
[0031] 2. Prepare chemical mixed fertilizer:
[0032] Mix urea, calcium hydrogen phosphate and potassium chloride according to the mass ratio (30-40):(35-45):(15-25), pulverize, and pass through a 150-200 mesh sieve to obtain a chemical mixed fertilizer.
[0033] 3. Preparation of livestock and poultry manure starter:
[0034] Livestock and poultry manure containing 90% or more is composted and fermented, deodorized, sterilized at an ambient...
