Embodiment 1
[0033] Embodiment 1, (taking corn stalk as main raw material, summer production is example)
[0034] Step 1: Chop 1,500 kg of fresh corn stalks and 500 kg of fresh weeds in the field to 1-3 cm, moisten the raw materials with clean water, and make the water content reach 70%, mix well and compost; the internal temperature reaches 70°C Afterwards, the compost was rotted for 3 days, during which it was turned every day to achieve the purpose of removing some bacteria and pathogens carried by the straw.
[0035] Step 2: Spread out and cool down naturally to 25°C to 30°C, add 25 kg of dipotassium hydrogen phosphate, 15 kg of calcium nitrate and 8 kg of urea according to the dry weight of the straw, and mix well.
[0036] Step 3: Stir in 150 kg of solid microbial agent of Group A (total bacterial density 5×10 9 each / gram, the adsorbent accounts for 75%), mix well and accumulate fermentation, the accumulation thickness is not more than 80cm, the control temperature is not more than ...
Embodiment 2
[0039] Embodiment 2, (with wheat straw as main raw material, summer production is example)
[0040] Step 1: Chop 800 kg of wheat straw and 200 kg of field weeds to 1-3 cm, moisten the raw materials with clean water, and make the water content reach 65%, mix well and compost; after the internal temperature reaches 70°C, The composting lasted for 5 days, during which it was turned every day to achieve the purpose of removing some bacteria and pathogens carried by the straw.
[0041] Step 2: Spread out and cool down naturally to 25°C-30°C, add 20 kg of dipotassium hydrogen phosphate, 10 kg of calcium nitrate and 10 kg of urea, and mix well.
[0042] Step 3: Stir in 150 kg of Group A liquid bacterial agent (total bacterial density 10×10 9 per gram, the protective agent is 1.5%), pile up and ferment after mixing well, the pile up thickness is not more than 80cm, the control temperature is not more than 40 ℃, after 7 days, mix in 70 kg of solid bacterial agents of group B (total ba...
Embodiment 3
[0045] Embodiment 3, (taking corn stalk as main raw material, production in winter is example)
[0046] Step 1: Chop 800 kg of corn stalks and 200 kg of rice straw to 1-3 cm, moisten them with clean water, and make the water content reach 75%, mix well and then compost; after the internal temperature reaches 65°C, compost for 10 Days, during which the stirring was done 5 times to achieve the purpose of removing some bacteria and pathogens carried by the straw.
[0047] Step 2: Spread and cool down naturally to 30°C to 35°C, add 25 kg of dipotassium hydrogen phosphate, 15 kg of calcium nitrate and 10 kg of urea, and mix well.
[0048] Step 3: Stir in 100 kg of solid bacterial agent of Group A (total bacterial density 20×10 9 per gram, the adsorbent accounts for 55%), pile up and ferment after mixing well, the pile up thickness is no more than 80cm, the control temperature is no more than 40°C, and after 8 days, mix in 80 kilograms of liquid bacterial agents of group B (total b...
