Embodiment 1

[0031] Example 1 A method for composting sheep manure, comprising the steps of:

[0032] (1) The sheep manure is air-dried to remove impurities, and then 2% and 10% of EFB and EP are added by volume fraction respectively to the sheep manure (the fine powder particles are removed by sieving with a 2mm sieve) to obtain a mixture;

[0033] (2) Adjust the moisture content of the above mixture to 60-70wt% and start composting, measure the temperature every day, when the temperature of the pile is higher than 50°C, turn the pile once every 2 days, when the temperature of the pile is 40-50°C , Turn the pile every 3 days; when the temperature of the pile body is lower than 40°C, turn the pile every 7 days. When the temperature of the heap is 20-30°C, the composting is completed.

[0034] Among them, the agricultural plant enzyme is obtained by mixing jujube, sugar, and water in a mass ratio of 3:1:10, and fermenting at a constant temperature of 30°C for 90 days.

Abstract

The invention provides a sheep manure composting method, which belongs to the technical field of agriculture, and comprises the following steps: (1) adding agricultural plant enzymes and expanded perlite into sheep manure to obtain a mixture; and (2) adjusting the moisture content of the mixture to 60-70wt%, starting composting, and finishing composting when the temperature of the compost body is20-30 DEG C. The sheep manure composting method provided by the invention is mainly applied to the field of agriculture, agricultural plant enzymes and expanded perlite are added in the method, the synergistic effect of the agricultural plant enzymes and the expanded perlite promotes nitrogen retention of compost, nitrogen loss is greatly reduced, the high-temperature period time is prolonged, andthe compost can be thoroughly decomposed.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for composting sheep manure. Background technique [0002] Sheep manure is rich in nutrients, such as nitrogen, phosphorus, potassium, etc. Generally, high-temperature aerobic fermentation technology is used to ferment sheep manure alone or with straw to co-ferment it into nutrient-rich organic fertilizer. However, in the current sheep manure composting process, the carbon-to-nitrogen ratio of sheep manure is too low, resulting in serious nitrogen loss in sheep manure composting, which seriously limits the application and promotion of composting products. [0003] In the prior art, reducing compost nitrogen loss is mainly through ex-situ nitrogen conservation technology or in-situ nitrogen conservation technology. Ex-situ nitrogen preservation technology mainly recycles the ammonia gas generated during the composting process, but the cost is relatively h...
