Problems solved by technology

However, the natural composting of pig manure to produce organic fertilizer not only takes a long time, but also causes a large amount of nutrients to be volatilized and lost during the composting process due to its unreasonable carbon-nitrogen ratio, and also causes air pollution.

Abstract

The invention relates to a pig manure fermented fertilizer and a preparation method thereof, belonging to the field of organic fertilizers. The invention aims to provide a pig manure fermented fertilizer and a preparation method thereof. The preparation method of the pig manure fermented fertilizer comprises the following steps of a, mixing biological bacteria, molasses and water and fermenting for 40-56h to obtain a bacterial fermentation liquid; b, mixing molasses, corns, water and the bacterial fermentation liquid and fermenting to obtain a primary fermentation material; c, after mixing pig manure, calcium superphosphate and the primary fermentation material, adding rice husks or saw dust and stirring to obtain a second fermentation material; d, composting the second fermentation material to ferment; e, continuing to ferment for 36-48h; and f, continuing to ferment for 36-48h to obtain the pig manure fermented fertilizer. Furthermore, the invention discloses a bio-organic fertilizer prepared from the pig manure fermented fertilizer provided by the invention. The pig manure fermented fertilizer is good in loose degree and contains more than 30% of organic matters; and 25-30g of nitrogen, phosphorus and potassium nutrients are contained in every 1kg of pig manure fermented fertilizer.

Description

technical field [0001] The invention relates to fermented pig manure fertilizer and a preparation method thereof, belonging to the field of organic fertilizers. Background technique [0002] With the development of animal husbandry, large-scale pig farms and pig farming communities have increased rapidly, but the subsequent large amount of pig manure disposal has become a major problem. The use of pig manure to produce bio-organic fertilizer not only solves the pollution caused by a large amount of pig manure accumulation to the environment, but also provides necessary organic fertilizer for the development of green and organic agriculture in development. Therefore, the production of pig manure organic fertilizer is an important solution for large-scale pig farms. The harm that pig manure may cause to the environment has found a more practical and effective way. However, the natural composting of pig manure to produce organic fertilizer not only takes a long time, but also ...
