Embodiment 1

[0019] After the horse manure is cleared from the horse farm, the horse manure is crushed with a crusher to make the thickness reach 2mm, and then an appropriate amount of nutritional supplementary materials (see Table 1) is added, stirred evenly, and prepared into a compost. Pour the culture material into the corresponding container, the height of the culture material is 4cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material, and the egg density is: 0.2g black soldier fly eggs / kg culture material. The culture temperature was 30°C, and the black soldier fly eggs hatched into larvae on the 2nd day, and began to decompose and transform the compost. On the 18th day, put a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of mature black soldier fly maggots. After 20-30 days, the black soldier fly larvae have reached the mature state, and they climbed out of the compo...

Embodiment 2

[0024] After the horse manure is cleared from the horse farm, the horse manure is crushed with a crusher to make the thickness reach 3mm, and then an appropriate amount of nutritional supplementary materials (see Table 2) is added, stirred evenly, and prepared into a compost. Pour the culture material into the corresponding container, the height of the culture material is 6cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material, and the egg density is: 0.6g black soldier fly eggs / kg culture material. The culture temperature was 25°C, and the black soldier fly eggs hatched into larvae on the 2nd day, and began to decompose and transform the compost. Properly replenish water during the cultivation process to prevent excessive temperature rise. On the 18th day, a larger container was placed outside the culture container, and dry rice bran powder was sprinkled into it to facilitate the collection of mature black soldier fly larvae. Af...

Embodiment 3

[0028] After the horse manure is cleared from the horse farm, the horse manure is crushed with a crusher to make the thickness reach 5mm, and then an appropriate amount of nutritional auxiliary materials (see Table 3) is added, stirred evenly, and prepared into a compost. Pour the culture material into the corresponding container, the height of the culture material is 8cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material, and the egg density is: 0.8g black soldier fly eggs / kg culture material. The culture temperature was 25°C, and the black soldier fly eggs hatched into larvae on the 2nd day, and began to decompose and transform the compost. Properly replenish water during the cultivation process to prevent excessive temperature rise. On the 18th day, set a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of mature larvae of mature black soldier flies. After 20...

Abstract

The invention discloses a method for preparing an organic fertilizer by utilizing horseshit processed by black soldier flies, and belongs to the technical of environment friendliness. The method comprises the following steps of: crushing the horseshit, so that the roughness is between 1 and 5 millimeters; adding auxiliary materials to form a compost; inoculating black soldier fly spawns on the surface of the compost, and culturing at the temperature of between 25 and 35 DEG C for 20 to 30 days; and collecting the compost, and drying to prepare the organic fertilizer, wherein the auxiliary materials are feather meal, meat and bone meal and globulin meal. The method is high in processing capacity, small in occupied areas and low in energy consumption in the processing procedure, a microbialorganic fertilizer and black soldier fly maggot biological protein are obtained while the horseshit is processed, the horseshit is recycled, wastes are converted into wealth, environment sanitation is improved, and the organic fertilizer and the biological protein are produced simultaneously, so the method is good in application prospect.

Description

technical field [0001] The invention relates to a manure treatment method, which belongs to the field of environmental protection, and in particular to a method for preparing organic fertilizer by using black soldier flies to process horse manure. Background technique [0002] Large-scale horse ranches, racetracks and horse trading markets produce a large amount of horse manure every day. If the weather is hot, if it is not treated in time, it will emit an unpleasant smell, which is very easy to breed mosquitoes and pathogenic microorganisms, affecting horses and breeding. The health of personnel and the sanitation of the ranch environment. At present, the main processing methods of horse manure are as follows: 1. Drying or drying them for lighting fires; 2. Sending them directly to landfills as garbage; 3. Using them for fermentation and composting. [0003] The advantage of the prior art is that the processing technology is simple and convenient; but there are also many d...
