Embodiment 1

[0027] The specific steps and process conditions of the preparation process of the present invention are as follows.

[0028] (1) Mixed fermentation materials. Add 900kg of chicken manure, 50kg of straw powder, 30kg of mushroom slag, 20kg of bran and 0.2kg of compound bacterial agent for organic fertilizer fermentation into the fermentation tank respectively, and mix well.

[0029] (2) Fermentation process. After the 5th day, the temperature of the pile body rose to above 55°C, and the pile began to be turned over every 3 days. Below ℃, and keep it for 10-15 days. At this time, the particles of the compost become smaller and flocculent, the texture is loose and not sticky, no special smell, the color is dark brown, and there are no mosquitoes and flies around, which conforms to the appearance of typical decomposed compost and can confirm the fermentation. Finish.

[0030] (3) Crush and sieve. The fermented organic fertilizer is air-dried until the water content reaches abo...

Embodiment 2

[0038] The specific steps and process conditions of the preparation process of the present invention are as follows.

[0039] (1) Mixed fermentation materials. Add 850kg of chicken manure, 70kg of straw powder, 20kg of mushroom dregs, 10kg of bran and 0.2kg of compound bacterial agent for organic fertilizer fermentation into the fermentation tank respectively, and mix well.

[0040](2) Fermentation process. After the 4th day, the temperature of the pile body rose to above 55°C, and the pile began to be turned over every 3 days. Below ℃, and keep it for 10-15 days. At this time, the particles of the compost become smaller and flocculent, the texture is loose and not sticky, no special smell, the color is dark brown, and there are no mosquitoes and flies around, which conforms to the appearance of typical decomposed compost and can confirm the fermentation. Finish.

Embodiment 3

[0049] The specific steps and process conditions of the preparation process of the present invention are as follows.

[0050] (1) Mixed fermentation materials. Add 850kg of chicken manure, 70kg of straw powder, 20kg of mushroom dregs, 10kg of bran and 0.2kg of compound bacterial agent for organic fertilizer fermentation into the fermentation tank respectively, and mix well.

[0051] (2) Fermentation process. After the 4th day, the temperature of the pile body rose to above 55°C, and the pile began to be turned over every 3 days. Below ℃, and keep it for 10-15 days. At this time, the particles of the compost become smaller and flocculent, the texture is loose and not sticky, no special smell, the color is dark brown, and there are no mosquitoes and flies around, which conforms to the appearance of typical decomposed compost and can confirm the fermentation.

Abstract

The invention discloses a preparing method for converting chicken dung into refined water-solubility organic fertilizers. The preparing method for the water-solubility organic fertilizers aims at solving the problems that as for organic fertilizer products generated by composting poultry dung, quality is instable, the heavy metal content exceeds the standard, certain foul smells exist, and automatic fertilizer applying is inconvenient. The preparing method for the water-solubility organic fertilizers is rapid, convenient, free of the foul smells and capable of achieving industrial mass production, and the obtained products have the advantages that the fertilizer efficiency is obvious, quality is stable, and automatic fertilizer applying is convenient.

Description

Technical field [0001] The present invention involves an organic fertilizer, especially the use of chicken manure to make refined water -soluble organic fertilizers. Background technique [0002] At present, with the rapid development of the poultry and livestock industry and the expansion of the breeding scale, more and more feces produced by poultry and livestock are increasingly prominent to the problems caused by the environment.According to data from the National Bureau of Statistics, in 2014, Chinese livestock and poultry manure emissions were more than 3 billion tons, which was 1.6 times that of the total industrial solid waste emissions during the same period.The proportion of the total amount of oxygen, ammonia nitrogen, and total phosphorus emissions of livestock and poultry breeding accounted for 95%, 78%, and 74%of the total emissions of agricultural sources.EssenceAmong them, chemical oxygen demand (COD) emissions are 3.23 times the amount of industrial sources and 1...
