specific Embodiment approach 1

[0008] Specific embodiment one: the culture medium of housefly larva in the present embodiment is made up of main material and water by the weight ratio of 5: 1, and described main material is made up of 32~37 parts of fresh chicken manures, 50~55 parts by weight. Parts of sawdust, 8-12 parts of wheat bran and 1-3 parts of urea.

specific Embodiment approach 2

[0009] Specific embodiment two: the substratum of housefly larva among the present embodiment is made up of main material and water by the weight ratio of 5: 1, and described main material is made up of 35 parts of fresh chicken manures, 53 parts of sawdust, 10 parts by weight. Consists of 1 part wheat bran and 2 parts urea. Mix well to make a thickness of 15 cm.

[0010] Feeding method: move the lured eggs into the larval incubator, the room temperature is lower than 25 degrees, and the temperature of the box is controlled at 30-40 degrees; the box is 145 cm long, 100 cm wide, and 20 cm high, and the material is 15 cm. The cultivation room is shaded 80%, uninterrupted supplementary light at night, the light source is a 200w incandescent lamp, 150 cm away from the culture medium.

[0011] Because there is sawdust, the permeability is good, and the larvae are evenly distributed in the substrate and grow normally; if there is no sawdust substrate, the temperature is too high, a...

specific Embodiment approach 3

[0012] Specific embodiment three: the substratum of housefly larva among the present embodiment is made up of main material and water by the weight ratio of 5: 1, and described main material is made up of 34 parts of fresh chicken manures, 54 parts of sawdust, 11 parts by weight. Consists of 1 part wheat bran and 1 part urea. Mix well to make a thickness of 15 cm.

[0013] Feeding method: move the lured eggs into the larval incubator, the room temperature is lower than 25 degrees, and the temperature of the box is controlled at 30-40 degrees; the box is 145 cm long, 100 cm wide, and 20 cm high, and the material is 15 cm. The cultivation room is shaded 80%, uninterrupted supplementary light at night, the light source is a 200w incandescent lamp, 150 cm away from the culture medium.

[0014] Because there is sawdust, the permeability is good, and the larvae are evenly distributed in the substrate and grow normally; if the temperature of the substrate without sawdust is too high...

Abstract

The invention belongs to the field of housefly breeding, and discloses a culture medium for housefly larve, which aims at solving the technical problems that the existing housefly larve culture medium is easy to mildew, great in temperature change, can easily produce alcohol, and cannot meet the requirement of the large-scale production. The culture medium for housefly larve is composed of main material and water according to weight ratio of 5:1, and the main material is composed of fresh chicken manure, saw powder, wheat bran and urea. The effective heating period of the culture medium is 7 days, and the culture medium is capable of heating after 2 hours, the culture medium can not be bonded into block and can not mildew easily, the temperature is easily controlled at 30-35 DEG C to inhibit the production of the alcohol, and the culture medium is suitable for large-scale production, capable of providing nutrient source and heat source as well as guaranteeing the growth requirement of the larve. The urea used by the culture medium can be used for adjusting the carbon nitrogen ratio of the microorganism nourishment and guaranteeing that the mass ratio of the carbon to the nitrogen is 25:1, and is used as an available nitrogen source. The saw powder used by the culture medium is not only the carbon source, but also is capable of improving the voidage and ventilation, and promoting the aerobic fermentation.

Description

technical field [0001] The invention belongs to the field of housefly breeding, and in particular relates to a culture medium for housefly larvae. Background technique [0002] The maggot is the larvae of the housefly, without head and feet, and white in color. Fly maggots feed on livestock and poultry manure, wheat bran, various rotten straws, vegetable leaves, bean cakes and other organic matter. They grow and reproduce very fast. Artificial breeding does not require a lot of equipment. It can be cultivated indoors and outdoors, in urban and rural areas. Fly maggot protein is high-quality protein, not only high-quality feed, but also extract protein powder, develop advanced nutrition, aerospace food, medicine, etc. The production of sterile fly maggot can drive poultry and livestock breeding, promote planting, and derive feed processing , food processing, etc. At present, the most direct use of fly maggots is as feed to feed conventional pigs, chickens, ducks, and fish. ...
