The use of organic fertilizer production line can effectively solve the environmental pollution caused by organic wastes from livestock and poultry breeding industry, reduce the eutrophication of surface water caused by pollution, improve the safety and quality of agricultural products, and lay a good foundation for the comprehensive consumption of green food and organic food. The ecological environment benefit is extremely significant. What should we pay attention to in the construction of organic fertilizer processing plant?

① The establishment of small-scale organic fertilizer production line should meet the requirements of environmental protection policy. Environmental protection is not only the desire of the people, but also the policy demand of agriculture and animal husbandry for environmental protection;

② The location of the raw materials, the location of the investment, the location of the raw materials, and the location of the investment;

③ Raw material variety, variety resolution, detailed equipment used in each process stage, affecting equipment investment price, etc;

④ The consumption scale and the annual output of the small-scale organic manure production line from 3000 tons to 20000 tons determine the capacity requirements of the equipment, thus affecting the price, etc;

⑤ The recycling application of resources needs to rely on a variety of agricultural purification waste recycling methods, such as making fuel and electricity raw materials first, and biogas residue as inorganic fertilizer raw materials;

⑥ The small-scale organic manure production line can be used as feed for other purposes;

⑦ Construction site: the demand determines the consumption site size and investment site size according to the consumption scale of the scheme.
