Embodiment 1

[0024] First, the dry base of hickory nut skin, rice straw and lake mud is pulverized respectively with a pulverizer, and the crushed particle size is 0.5 cm, which is 70% of hickory nut skin, 10% of rice straw, and 20% of lake mud by weight percentage. % ratio for uniform mixing, after mixing, adjust the water content of the mixture to 60%.

[0025] Then, in the mixture, add 0.2% Gulin microbial fermentation inoculum by weight percentage, after stirring evenly, press the pile height 1.7m, the standard of pile width 2.5m is piled up in the fermenter, makes pile body heat up and keeps 60- 65°C, according to the temperature change, turn the pile once every 2 days. When the pile temperature begins to drop to 40°C in 12 days, stop turning and remove the mixture.

[0026] Finally, pile the removed mixture into piles according to the pile height of 1.5m, pile width of 2.5m, and unlimited length, and use wooden sticks to insert holes on the top and side, with a density of 6 pieces / m ...

Embodiment 2

[0028] First, the dry base of hickory nut skin, rape stalk and river mud is pulverized respectively with a pulverizer, and the crushed particle diameter is 0.3 cm, which is 65% of hickory nut skin, 20% of rape straw and 15% of river mud by weight percentage. % ratio for uniform mixing, after mixing, adjust the water content of the mixture to 65%.

[0029] Then, in the mixture, add 0.3% Gulin microbial fermentation inoculum by weight percentage, after stirring evenly, press the pile height 2.0m, the standard of pile width 2.0m piles up in the fermenter, makes pile body heat up and keeps 60- 65°C, turn the pile every 2 days according to the temperature change, and stop turning when the pile temperature starts to drop to 43°C in 10 days, and remove the mixture.

[0030] Finally, pile the removed mixture into piles according to the pile height of 2.0m, pile width of 3.0m, and unlimited length, and use wooden sticks to insert holes on the top and side, with a density of 5 pieces / m ...

Embodiment 3

[0032] First, the dry basis of the three materials, hickory nut skin, rice straw and lake mud, is pulverized respectively by a pulverizer, and the crushed particle size is 1.0 cm, which is 80% of hickory nut skin, 5% of rice straw, 5% of rice straw, The ratio of 15% of lake mud is uniformly mixed, and after mixing, the water content of the mixture is adjusted to 62%.

[0033] Then, in the mixture, add 0.3% Gulin microbial fermentation inoculum by weight percentage, after stirring evenly, press the pile height 1.5m, the standard of pile width 3.0m piles up in the fermenter, makes pile body heat up and keeps 60- 65°C, turn the pile every 3 days according to the temperature change, and stop turning the pile when the pile temperature begins to drop to 45°C in 10 days, and remove the mixture.

[0034] Finally, pile the removed mixture into piles according to the pile height of 1m, pile width of 2.8m, and unlimited length, and use wooden sticks to insert holes on the top and side, w...

Abstract

The invention discloses a method for treating hickory epicarp to produce fertilizers. The method mainly comprises the following four steps of: raw material pretreatment, microbial strain inoculation, aerobic fermentation and aging. The raw materials (percentage by weight) are as follows: 60% to 80% of hickory epicarp, 5% to 20% of crop stalks and 15% to 20% of lake mud; and the inoculated fermentation strain is Gulin microbial preparation accounting for 0.1% to 0.3% the weight of the raw material mixture. Based on the high-temperature aerobic composting technique in combination with the aid of fermentation stain, the method can treat the waste hickory epicarp, crop stalks and lake mud to produce organic fertilizers rich in potassium and various medium / micro elements; and the organic fertilizers are applied to farmlands to provide sufficient nutrients to crops, improve the physicochemical properties of soil and improve soil fertility. The resources of raw materials are abundant, the process is simple, and the organic fertilizers can be widely applied in agricultural production.

Description

technical field [0001] The invention relates to a treatment method for transforming pecan exocarp, straw and lake mud or river mud into organic fertilizer by using high-temperature aerobic composting technology, and belongs to the technical field of environmental protection. Background technique [0002] The weight of pecan exocarp accounts for 70% of the weight of the whole green-skinned walnut. Untreated piles are piled up in the wild. The leachate produced after soaking in rainwater and microbial fermentation not only pollutes water sources, leads to the death of fish and shrimp, but also damages the vegetation in mountainous areas. and crops, etc., affecting their normal growth. [0003] The production of hickory nuts in my country is relatively concentrated, mainly distributed in the Tianmu mountainous area at the junction of Zhejiang and Anhui. A large number of untreated hickory nut peels piled up and thrown in the wild have caused serious pollution to the ecological ...
