Problems solved by technology
But the current technical difficulties are: first, it is very difficult to rot, so people first crush the straw, which brings about the second difficulty: mechanical crushing consumes a lot of energy, wears a lot, and the maintenance cost is high. This is because Raw straw is tough and fibrous, and it is very difficult to crush and cut
Even after shredding, it is still basically ineffective, and it will still damage the soil structure and affect cultivation

Embodiment Construction
[0028] The following is an example of the operation process of a straw 1 fermentation point to describe the specific implementation method of the present invention.
[0029] The basic information is as follows:
[0030] The single-seat silo has a diameter of 15 meters, an average height of 8 meters, and a volume of about 1,400 cubic meters;
[0031] A single silo can store straw 1: 1400X0.5 = 700 tons, and can serve about 700 / 0.5 = 1400 mu of farmland;
[0032] According to the calculation that 1 ton of straw can absorb 0.2 tons of manure, a single silo can store manure: 700X0.2 = 140 tons;
[0033] According to sending a trip of manure every 9 days, 7 tons of manure per car, 180 days (half a year) can deliver manure: 180 / 9 = 20 times, total: 20X7 = 140 tons, that is, a single silo can hold Half a year of manure.
[0034] Straw 1 is generated twice a year: wheat straw 1 in May and rice straw 1 in November;
[0035] A total of 4 silos will be built, including 1 silo for exc...

The invention provides a composting method of agricultural residues and silos, which are pollution control projects and belong to the field of environmental protection engineering. Straws produced in more than one thousand mu of farmland can be served nearby and plenty of livestock and poultry excrement can be stored up and disposed by looking for an agricultural residue fermenting and composting spot in the countryside and building a number of large silos for cycle operation. The technological processes are as follows: stacking the straws in the silos, continuously pouring livestock and poultry excrement and liquid dung into the straw stacks in the silos to enable the straws to fully absorb the livestock and poultry excrement and liquid dung, then sealing the silos to carry out static anaerobic fermentation until the straws and the excrement are composted thoroughly and returning the organic fertilizers to the fields after the straws and the excrement become genuine organic fertilizers. The composting method has the effect of producing the high-quality organic fertilizers while eliminating straw and livestock and poultry excrement pollution, thus truly realizing the effect of turning waste into wealth.
Description
technical field [0001] A method for decomposing agricultural waste and a silo according to the invention are agricultural waste pollution control projects and belong to the field of environmental protection engineering. Background technique [0002] Severe air pollution caused by straw burning in rural areas has been banned. However, the amount of straw is large and it is not suitable for long-distance transportation, so if it can be converted into organic fertilizer on the spot, it should be the best choice. But the current technical difficulties are: first, it is very difficult to rot, so people first crush the straw, which brings about the second difficulty: mechanical crushing consumes a lot of energy, wears a lot, and the maintenance cost is high. This is because Raw straw is tough and fibrous, and it is very difficult to crush and cut. Even after chopping, it is still basically ineffective, and it will still damage the soil structure and affect cultivation. Therefor...
