Embodiment 1

[0019] Stir 55kg of feces and 10kg of straw evenly to obtain a mixture, add 6kg of deodorizing bacteria to ferment, the fermentation temperature is 75°C, turn the pile repeatedly, and turn the pile 3 times during the whole fermentation process, once every 3 days, and dehydrate to reduce the weight of the mixture Reduced by 70%; then add 6kg superphosphate, 6kg oil cake, 3kg sugar solution, 4kg plant ash, 4kg zeolite powder and 6kg functional bacteria, stir evenly, stack for 3 days, crush to 20 mesh, measure and pack for storage, and obtain 54.5kg of finished product, the conversion rate of organic matter is 83.8%. The relevant test results of this product are shown in Table 1.

Embodiment 2

[0021] Stir 50kg of feces and 10kg of straw evenly to obtain a mixture, add 7kg of deodorizing bacteria to ferment, the fermentation temperature is 75°C, turn over the pile repeatedly, and turn over the pile 3 times during the whole fermentation process, turn over once every 4 days, and dehydrate to reduce the weight of the mixture Reduced by 80%; then add 8kg superphosphate, 8kg oil cake, 5kg sugar solution, 2kg plant ash, 3kg zeolite powder and 7kg functional bacteria, stir evenly, stack for 4 days, crush to 20 mesh, measure and pack for storage, and obtain 52kg finished product, the conversion rate of organic matter is 86.7%. The relevant test results of this product are shown in Table 1.

Embodiment 3

[0023] Stir 45kg of feces and 15kg of straw evenly to obtain a mixture, add 8kg of deodorizing bacteria to ferment, the fermentation temperature is 75°C, turn over the pile repeatedly, and turn over the pile 4 times during the whole fermentation process, once every 3 days, and dehydrate to reduce the weight of the mixture Reduced by 75%; then add 7kg superphosphate, 7kg oil cake, 4kg sugar solution, 3kg plant ash, 4kg zeolite powder and 7kg functional bacteria, stir evenly, stack for 5 days, pulverize to 20 mesh, measure and pack for storage, and obtain 55kg finished product, the conversion rate of organic matter is 91.7%. The relevant test results of this product are shown in Table 1.

Abstract

The invention relates to an organic fertilizer and a preparation method thereof. A formula of the organic fertilizer comprises by weight: 40%-60% of excrement, 3%-15% of straw, 5%-10% of deodorization strains, 4%-10% of calcium superphosphate, 4%-10% of oil cake, 2%-5% of sugar liquid, 1%-6% of ash, 1%-6% of a zeolite powder and 3%-9% of functional bacteria. The preparation method comprises the steps of fermentation and blending. The invention has the beneficial effects of effectively controlling stink of manure and reducing fermentation time to avoid environmental pollution, and reducing the production cost.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly, and is developing in the direction of specialization, scale and intensification. At the same time, more and more wastes are discharged from the breeding industry. Livestock manure contains a large amount of organic pollutants, and COD alone reaches 71.18 million tons, far exceeding the sum of COD of industrial and domestic sewage pollutants. At present, due to financial and technical reasons, the rate of harmless, resourceful and commercial treatment of feces is less than 5%. Large-scale livestock and poultry farming has become the main source of environmental pollution in rural areas of our country, causing great pressure on the ecological environment. It has become one of the main obstacles restricting the sustainab...
