Problems solved by technology

However, the winter temperature in the Jiangnan area is below 10°C, or even as low as 0°C, which is very unfavorable to the growth of fly maggots; on the other hand, the current land resources are tight, especially in the Jiangnan area.

Embodiment 1

[0024] The two-step breeding method for fly maggots is to place the hatched housefly larvae in a greenhouse for intensive treatment in spring; the specific steps are:

[0025] (1) Strengthening treatment stage

[0026] In the indoor breeding pond, pre-lay 5cm thick breeding material; then transfer the housefly larvae within 24 hours after hatching to the breeding material; during the breeding process, the indoor temperature is controlled to be above 20°C, and the breeding density of the housefly larvae 9.6×10 7 Bar / m 2 , breeding time 1 day;

[0027] (2) Ordinary breeding treatment stage

[0028] The housefly larvae after intensive treatment were taken out from the breeding pond and put into the biomass waste to continue breeding; during the breeding process, the temperature of the greenhouse was controlled above 10°C, and the maggot residue was separated after 5 days, and the fresh maggots were cleaned.

[0029] The breeding material is: a combination of livestock manure,...

Embodiment 2

[0032] The two-step breeding method for fly maggots is to place the hatched Chrysocephala larvae in a greenhouse for intensive treatment in autumn; the specific steps are:

[0033] (1) Strengthening treatment stage

[0034] In the indoor breeding pot, pre-lay 7cm thick breeding material; then transfer the Chrysocephala larvae within 24 hours after hatching to breeding in the breeding material; control the indoor temperature during the breeding process to be above 20°C, and the growth rate of the Chrysocephala larvae The breeding density is 9.6×10 5 Bar / m 2 , breeding time 2 days;

[0035] (2) Ordinary breeding treatment stage

[0036] The enhanced treatment of Chrysocephala macrocephala larvae was taken out of the breeding pot and put into the biomass waste to continue breeding; during the breeding process, the indoor temperature was controlled to be above 10°C, and the maggot residue was separated after 4 days to clean the fresh maggots.

[0037] The breeding material is:...

Embodiment 3

[0040] The two-step breeding method for fly maggots is to place the hatched blowfly larvae in a greenhouse for intensive treatment in winter; the specific steps are:

[0041] (1) Strengthening treatment stage

[0042] In the breeding pond in the greenhouse, pre-lay 10cm thick breeding material; then transfer the erythrophyll larvae within 24 hours after hatching to the breeding material for breeding; control the temperature of the greenhouse during the breeding process to be above 20°C, and the larvae of the red-headed blowfly The breeding density is 8×10 6 Bar / m 2 , breeding time 3 days;

[0043] (2) Ordinary breeding treatment stage

[0044] After intensive treatment, the blowfly larvae were taken out from the breeding pond and put into the biomass waste to continue breeding; during the breeding process, the temperature of the greenhouse was controlled above 0°C, and the fresh maggots were separated after 6 days to clean the fresh maggots.

[0045] The breeding material ...

Abstract

The invention relates to a breeding technology of fly maggots and aims to provide a method for breeding fly maggots in two steps under conditions of normal temperature and low temperature. The method is characterized by adding an enhanced treatment stage before the common breeding treatment method and retaining high environment temperature of the former growth period in a manner of increasing the breeding density of larvae of fly maggots, and increasing independent room temperature or providing coverage for the larvae. The enhanced process can be used for improving the features and the nutritional characteristics of the breeding materials; the growth condition of the larvae of fly maggots can be improved; the growth of the fly maggots can be improved; the indoor enhanced process can be used for improving the growth environment of the larvae of fly maggots by increasing the temperature; the relative temperature-increasing cost is low; the larvae of fly maggots after the enhanced treatment are large in larva instar and size and high in resistance to low temperature; the survival rate of the larvae of fly maggots under the condition of the relative low temperature is higher than that of the larvae which are just hatched in 24 hours. The method can be used for increasing the utilization rate of the land; the biomass waste fly maggots such as excrements of livestock can be annually treated; the method has great effects on enterprise benefit and development and quick and effective treatment on the excrements of livestock.

Description

technical field [0001] The invention relates to a fly maggot culture technology, in particular to a two-step fly maggot culture process under normal temperature and low temperature conditions. Background technique [0002] China produces a huge amount of biomass waste every year, including more than 2 billion tons of livestock and poultry manure. Composting technology is currently the main method for the harmless and resourceful treatment of biomass waste such as livestock and poultry manure. The high-value composting process of using fly maggots to treat biomass waste such as livestock and poultry manure can not only make the biomass waste such as livestock and poultry manure harmless and resourceful to obtain high-quality organic fertilizer, but also provide a large amount of high-quality organic fertilizer for the aquaculture industry. High-quality insect protein can realize "turning waste into treasure, saving energy and reducing emissions, and protecting the environment...
