Pig manure fermentation site construction and fermentation method

Abstract

The invention discloses a pig manure fermentation site construction and fermentation method, and belongs to the technical field of pig manure fermentation. The pig manure fermentation site construction and fermentation method comprises the following steps: pouring the ground of a pig manure stacking field to form an inclination of 5 degrees, building a small ditch with the width of 25cm and the depth of 20cm at the edge of the lower side of the ground, so that pretreated material exudate flows into a urine storage tank through the small ditch, urine leached from pig manure is effectively discharged, and the situation of mildewing during fermentation is prevented; determining the construction size of a fermentation workshop of a ten thousand pig farms to be 20-30m long, 7.5-8m wide and 3.5mhigh, selecting a sunshine plate as a cover top, so that the room temperature in the fermentation workshop is increased after penetrating of solar heat energy through the sunshine plate, increasing of the initial temperature of fermentation materials is accelerated, wherein ventilation holes are reserved in the top so that gas such as water vapor generated during material fermentation can be dissipated and exhausted.

Description

technical field [0001] The invention relates to the technical field of pig manure fermentation, in particular to a construction of a pig manure fermentation site and a fermentation method. Background technique [0002] Pig manure is rich in nutrients, containing 15% of organic matter, 0.5% of nitrogen (N), 0.5-0.6% of phosphorus (P205), and 0.35-0.45% of potassium (K20). Microorganisms decompose and release effective nutrients that can be absorbed and utilized by plants. [0003] However, some pig farmers do not build composting sites, causing a large amount of pig manure to accumulate and become moldy, and it is difficult to discharge pig urine. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a pig manure fermentation site construction and fermentation method, which solves the problem that some pig farmers do not build a composting site, causing a large amount of pig ma...
