To process organic manure with cow dung, the cow dung must first be aired or drained to keep the moisture below 85%. Then the end of the straw is added. The ratio of cow dung to straw dung is 7:3, making the raw material (cattle dung) The carbon ratio of the supplementary material (straw) is controlled at 23-28, and the moisture content is controlled at 52%-68%. Finally add the organic fertilizer ferment decomposer. After the raw materials, excipients and fungicide are mixed and stirred, they can be fermented on the heap. The requirements of the stack are that the mixture is piled on the fermentation field with a bottom width of 1.8 to 3 meters, with an upper width of 0.8 to 1 meter and a height of 1 to 1.5 meters. Trapezoid bars are spaced 0.5 meters apart. After the stack is ready, the temperature will rise above 60°C within 24-48 hours, and the temperature will be maintained for 48 hours before turning over. When turning the stack, it must be even and thorough. Put the low-level material into the upper middle of the pile as much as possible to fully decompose. After the first turn, it will be piled once a week. However, when the temperature exceeds 70°C, it must be immediately turned over. Otherwise, the beneficial microorganisms and the fermentation bacterium will be killed in large quantities, which is not conducive to fermentation and decomposition. Full fermentation maturity standards: One is to see the colors. The color of the general fertilizer turns brown or dark brown, and the ammonium nitrogen content increases significantly. The second is to see the leachate. Let the organic fertilizer add water (1:5) and stir for 5 minutes to see the color of the leachate. The third is to see the volume. The volume of decomposed compost collapsed by 1/3-1/2 of the newly built bark. Finally, the fermented organic fertilizer is evenly spread on the drying field, the thickness should not exceed 20 cm, and it is often sun-dried so that the water content is less than 32%.
