Embodiment 1

[0024] Experimental group: 110kg of fresh pig manure and garbage (50kg of feces and 60kg of urine), add 40kg of worm manure produced by raising black soldier flies in the previous batch, mix well, use citric acid, sodium citrate and sodium bicarbonate ternary The pH value of the mixture was adjusted to 4.5, and the moisture content was 55%. The mixture was stacked in a culture pond and fermented aerobic at 65° C. for 2 days. Take 10kg of the above-mentioned mixed material, spread the mixed feed with a thickness of 5 to 10 cm per square meter, and spread it evenly on the bottom of the breeding box, put 5 grams of black soldier fly eggs in the breeding box, and control the temperature at 32 ℃. Black soldier fly larvae were obtained after 3 days, and continued to be reared to obtain 6-day-old black soldier fly larvae.

Embodiment 2

[0028] Experimental group 1: 110kg of fresh pig feces and garbage (50kg of feces and 60kg of urine), add 40kg of worm dung material produced by raising black soldier flies in the previous batch, mix well, and use a ternary mixture of lactic acid, calcium hydroxide and sodium acetate. The pH value was adjusted to 7.5, and the moisture content was 70%. After adding the fermented microbial inoculum, the mixture was piled up in a culture pond and fermented aerobic for 2 days at 60°C. Take 10kg of the above-mentioned mixed material, spread the mixed feed with a thickness of 5 to 10 cm per square meter and spread it evenly on the bottom of the breeding box, put 2 grams of black soldier fly eggs in the breeding box, and control the temperature at 28 ℃. Black soldier fly larvae were obtained after 3 days, and continued to be reared to obtain 6-day-old black soldier fly larvae.

Embodiment 3

[0034] Collect 100kg of fresh pig manure and garbage (45kg of feces and 55kg of urine), add 50kg of worm manure produced by raising black soldier flies in the previous batch, mix well, and adjust the pH value with a ternary mixture of malic acid, calcium hydroxide and sodium carbonate was 6.0, and the moisture content was 65%. After adding the fermentation microbial inoculum, the mixture was piled up in the culture pond and fermented aerobic at 65°C for 2 days. Take 10kg of fermented material, spread the mixed feed with a thickness of 5 to 10 cm per square meter and spread it evenly on the bottom of the breeding box. Put 5 grams of black soldier fly eggs in the breeding box. The temperature is controlled at 32 ° C, and incubated for 3 The black soldier fly larvae were obtained in the day, and the 5-day-old black soldier fly larvae were continuously raised. Add 1.2 kg of 5-day-old black soldier fly larvae, and continue to raise for 12 days at 24°C. After sieving, 35.2 kg of gro...

Abstract

The invention relates to the technical field of waste resourceful utilization in the breeding industry, in particular to a method for resourceful treatment of pig manure garbage by using hermetia illucens, which comprises the following steps: mixing pig manure, pig urine and hermetia illucens manure, then adding an acid-base regulator to control the pH value to 4.5-7.5, regulating the water content to 55-70% by using the pig urine, and then adding an acid-base regulator to regulate the water content to 55-70% by using the hermetia illucens manure; after a fermentation microbial agent is added, performing aerobic fermentation for 2-4 days in an environment of 60-65 DEG C to obtain a culture material; the black soldier fly larvae are hatched and fed with the culture material until the black soldier fly larvae are 3-7 days old, then 20-50 kg of the culture material is added into every 1 kg of the black soldier fly larvae, the temperature is controlled to be 22-32 DEG C, the black soldier fly larvae are fed for 7-13 days, and then the black soldier fly larvae are separated from the black soldier fly feces. According to the method, the environmental protection problem of pig manure waste can be solved, the yield of hermetia illucens can be increased, the economic benefits of pig breeding enterprises are increased, and sustainable development of the green low-carbon pig breeding industry is achieved.

Description

technical field [0001] The invention relates to the technical field of resource utilization of wastes in the breeding industry, in particular to a method for utilizing black soldier flies to recycle pig manure and waste. Background technique [0002] Animal husbandry is a pillar industry of agricultural and rural economy and a symbolic industry of agricultural modernization. In 2020, the total output value of my country's animal husbandry will exceed 4 trillion yuan, reaching 4,026.667 billion yuan, accounting for 29.2% of the total agricultural output value, but at the same time, a large amount of animal manure and waste will seriously affect the ecological environment. According to the statistics of China Research Network, in 2020, the total discharge of livestock and poultry manure in my country will exceed 4 billion tons, and the total amount of pig manure will reach 746 million tons. Promoting the use of black soldier flies to achieve low-carbon green and resource-base...
