Problems solved by technology

[0008] In addition, during the breeding process of black soldier flies, it was found that the lack of timely addition of food or a small amount of single feeding would lead to a rapid drop in the humidity of the food and slow growth of the larvae; too much single feeding of the larvae could not be degraded in time would lead to high humidity in the food, caking, Moldy, severe heat generation of insect feeding materials, etc., which will affect the degradation and utilization of food materials and the growth and development of larvae
Generally, black soldier fly feed is fed daily, and the use of leftover food is easier to keep moisture than artificial feed. The existing technology adopts one-time feed feeding, which saves labor, but there is still room for improvement in the utilization of black soldier fly eggs. Optimizing the inoculation The amount, feeding amount and feeding frequency are beneficial to the transformation and utilization of meal waste by black soldier fly larvae, and can also effectively save labor input

Embodiment 1

[0034]The moisture content of the collected meal waste classified by non-technical means is measured, and the weight of meal waste and supplementary wheat bran required for each square meter of feed to reach a water content of 65% is calculated. The first feeding amount per square meter in the feeding container is 4.52 kg, and then about 100,000 6-day-old larvae were placed on the surface of the feed, and then 9.05kg, 11.31kg, 4.52kg, and 4.52kg of feed were added to the 9th, 12th, 15th, and 17th day-old larvae respectively. 30 ℃ 10h, 26 ℃ 14h cycle, relative humidity 65%. During the feeding period, the insect feed was turned 1-2 times a day to ventilate and dissipate heat. During the growth of black soldier fly larvae, meal waste is degraded. After 13 days of feeding, the black soldier fly larvae turn from white to grayish brown. After sieving, 6.3kg of black soldier fly larvae are obtained per square meter. The fluffy is dark brown, the water content is reduced to 27.87%, a...

Embodiment 2

[0036] The moisture content of the collected meal waste classified by non-technical means is measured, and the weight of meal waste and supplementary wheat bran required for each square meter of feed to reach a water content of 65% is calculated. The first feeding amount per square meter in the feeding container is 4.52 kg, and then about 100,000 6-day-old larvae were placed on the surface of the compost, and then 6.79kg, 9.05kg, 4.52kg, 4.52kg, and 4.52kg of feed were added to the larvae at the 9th, 13th, 15th, 17th, and 20th day-old respectively. kg, the feeding environment temperature was 26°C for 10 hours, 20°C for 14 hours, and the relative humidity was 65%. During the feeding period, the insect feed was turned 1-2 times a day to ventilate and dissipate heat. During the growth of black soldier fly larvae, meal waste is degraded. After 16 days of feeding, the black soldier fly larvae turn from white to grayish brown. After sieving, 6.74kg of black soldier fly larvae are ob...

Embodiment 3

[0038] The moisture content of the collected meal waste classified by non-technical means is measured, and the weight of meal waste and supplementary wheat bran required for each square meter of feed to reach a water content of 64.5% is calculated. The first feeding amount per square meter in the feeding container is 6.41. kg, and then about 147,000 6-day-old larvae were placed on the surface of the feed, and then 12.82kg and 16.03kg of feed were added to the 9th and 13-day-old larvae respectively. The feeding conditions were 19.5-29.6°C, RH16.8%~ 67.56%, indoor natural light. During the feeding period, the insect feed was turned 1-2 times a day to ventilate and dissipate heat. During the growth of black soldier fly larvae, meal waste is degraded. After 13 days of feeding, the black soldier fly larvae turn from white to grayish brown. After sieving, 7.01kg of black soldier fly larvae are obtained per square meter. The fluffy is dark brown, the water content is reduced to 27.7...

Abstract

The invention discloses a method for feeding hermetia illucens larvae by using kitchen waste. Kitchen waste obtained by front-end classification with a non-technical means is directly mixed with auxiliary materials in a certain proportion to form a feeding material with water content of 64.5%-68% to feed hermetia illucens larvae, and the auxiliary materials are plant fiber type auxiliary materialssuch as wheat bran. Compared with a method for crushing kitchen waste before feeding, the method has the advantages that the humidity of non-degraded residual materials is low, weight is only 2%-6% of the addition quantity, and crushing is more convenient and easier; the utilization rate of hermetia illucens eggs is at least increased by 32%-56.5% as compared with the prior art; the weight of hermetia illucens larvae obtained from every ton of kitchen waste is at least increased by 24%-118% as compared with the prior art, and the kitchen waste can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of insect breeding, and in particular relates to a method of raising black soldier flies ( Hermetia illucens ) larval approach. Background technique [0002] Food waste refers to the food waste formed by residents in the process of daily consumption. It is characterized by being extremely perishable and deteriorating. If it is not handled properly, it will cause many environmental problems, and even breed germs, affecting the health of humans or livestock. Compared with other wastes, kitchen waste has high water content, high organic matter content, high oil content and salt content, and rich nutrients, which has great recycling value. [0003] According to conservative estimates, in 2011, the annual output of urban kitchen waste in my country was not less than 7 million tons, and kitchen waste accounted for about 40-50% of the total urban waste. Food waste is mainly disposed of by being mixed with general waste ...
