Embodiment 1

[0027] Weigh 1000kg of cow dung and 200kg of straw, pre-built a drying shed with four walls left empty, spread the cow dung evenly in the drying shed for natural drying until the water content of the cow dung is 20%, then crush the cow dung; Crushing, mixing the crushed cow dung and straw evenly, the pre-fermented material is processed in a pile, and the water content is controlled to 50% by spraying to add water; then 1kg of compound is sprayed evenly on the piled fermented material Strains and 0.5kg of compound fermentation enzymes are covered with waterproof materials on the fermentation materials to avoid rain; oxygen is regularly introduced into the fermentation materials during the fermentation period to control the temperature of the fermentation materials. When the temperature reaches 50℃, The pile of fermented materials is turned over; after 5 days of fermentation, the materials are kept in the state of piles without oxygen and controlled temperature. After aging for 2 ...

Embodiment 2

[0031] Weigh 1100 kg of cow dung and 240 kg of straw, pre-built a drying shed with four walls left empty, spread the cow dung evenly in the drying shed for natural drying until the moisture content of the cow dung is 18%, then crush the cow dung; Crush, mix the crushed cow dung and straw evenly, and process the pre-fermented material into a pile, and control its moisture content to 54% by spraying to add water; then spray 1.5kg evenly on the piled fermented material Compound strains and 0.8kg of compound fermentation enzymes are covered with waterproof material on the fermentation materials to avoid rain; during the fermentation period, oxygen is regularly introduced into the fermentation materials to control the temperature of the fermentation materials. When the temperature reaches 56°C, Turn over the pile of fermented materials; after 6 days of fermentation, keep the materials in the state of piles, no more oxygen and control the temperature, and aging for 3 days.

Abstract

The invention discloses a dairy manure biological organic fertilizer which is prepared from dairy manure, straws, a compound culture and a compound fermentation enzyme. The invention also discloses a preparation method of the organic fertilizer. The preparation method comprises the following steps: crushing and uniformly mixing dehydrated dairy manure and straws and performing pile fermentation; uniformly spraying the compound culture and the compound fermentation enzyme for fermentation; introducing oxygen at a fixed time; detecting the temperature of the pile fermenting fermented material; turning the pile fermenting fermented material; and then aging the fermented material to obtain the organic fertilizer. By adopting various microorganisms to ferment the dairy manure to produce the biological organic fertilizer, pathogenic bacteria can be killed and quickly deodorized by means of a fermenting action of the microorganisms; then, the biological organic fertilizer disclosed by the invention is rich in nutritional components needed for growth and development of crops, and can also serve as a soil conditioning agent, so that phenomena of soil agglomeration and salinization are effectively improved. The dairy manure biological organic fertilizer disclosed by the invention is fast and full to decompose, the fermentation time is shortened, the production cost is favorably lowered, and industrial production is facilitated.

Description

Technical field [0001] The invention relates to the technical field of agriculture, in particular to a dairy cow manure biological organic fertilizer and a preparation method thereof. Background technique [0002] With the rapid development of the industrialization of my country’s dairy industry and the expansion of the scale of dairy cow production, the dairy industry provides a large amount of high-quality, safe raw milk for dairy processing, meets people’s nutritional and health requirements, and promotes social and economic development. Organic solid wastes and high-concentration organic wastewater, among which cow manure is rich in organic matter and plant nutrients, is a good organic fertilizer resource. However, a large amount of manure is returned to the field at will without any treatment. Due to the unreasonable nutrient combination, some nutrients are wasted. Secondly, the direct application of a large amount of nutrients and various elements of manure can also cause th...
