Embodiment 1

[0020] The rice straw is mechanically crushed into 2-5cm particles, and then the two are evenly mixed according to the dry weight ratio of straw: kitchen waste = 1000g: 4000g. Spread the mixed material on the bottom of the breeding box, the thickness of the material is 30cm, adjust the water content of the material to 65%, add 100g of 1-3 day-old black soldier fly larvae, the calculated breeding density is about 100g / ㎡, and the breeding environment temperature is kept at 28°C, ensure the ventilation of the shelf and the bottom (depending on the situation, it may be necessary to increase the blower). Sieve and separate after breeding for 12 days to obtain 550g of black soldier fly larvae and 2900g of high-quality organic fertilizer.

Embodiment 2

[0022] The corn stalks are mechanically crushed into 2-5 cm particles, soaked in 0.1% alkali solution for 8 hours, filtered, and mixed evenly according to the dry weight ratio of straw:fresh pig manure=1000g:4000g. Spread the mixed material on the bottom of the breeding box, the thickness of the material is 30cm, adjust the water content of the material to 65%, add 100g of 1-3 day-old black soldier fly larvae, the breeding density is 100g / ㎡, and the temperature of the breeding environment is kept at 28°C. Ensure the ventilation of the bracket and the bottom (appropriately add a blower). Sieve and separate after breeding for 10 days to obtain 500g of black soldier fly larvae and 3000g of high-quality organic fertilizer.

Embodiment 3

[0024] The rice straw is mechanically crushed to about 5 cm, soaked in 0.1% ammonia water for 8 days, filtered, mixed according to the dry weight ratio of straw: kitchen waste = 20kg: 80kg, and the water content of the material is adjusted to 65%. Spread the mixed materials in the breeding boxes respectively, the material thickness is 30cm, put the breeding boxes on the metal frame, add about 100g of 1-3 day old black soldier fly larvae to each breeding box, and the breeding density is 100g / ㎡, The temperature of the breeding environment was kept at 28°C to ensure the ventilation of the breeding box and the bottom. After breeding for 12 days, the material was separated from the black soldier flies. A total of 11kg of black soldier fly larvae and 60kg of high-quality organic fertilizer were obtained.

Abstract

The invention relates to a method for high-density culture of hermetia illucens larvae and high-efficiency transformation of organic wastes. By improving a culture container, air circulation and heatexchange are increased, and thus high-density culture of hermetia illucens and high-efficiency transformation of the organic wastes are realized by using a culture medium prepared by crop straw particles and kitchen wastes or poultry and livestock manure. The method effectively avoids burning of crop straws, contributes to environmental protection, and reduces culture cost of hermetia illucens. The method has important values and significances for realizing large scale and industrialized culture of hermetia illucens.

Description

technical field [0001] The invention relates to the technical field of biological breeding and straw biological conversion, in particular to a method for high-density breeding of black soldier fly larvae and efficient conversion of organic waste. Background technique [0002] Black soldier fly larvae are saprophytic insects, and their feeding range is extremely wide. They can feed on industrial, agricultural, domestic and other organic wastes, as well as animal and plant remains. They can also digest and decompose harmful bacteria in the process of organic waste corrosion, which can reduce Environmental hazards of organic waste. [0003] The black soldier fly larva, which is cultivated from organic waste, is an important energy insect. During the biotransformation process of organic waste, black soldier flies can form their own organic matter, of which protein content is 20%-70%, amino acid content is 30%-60%, fat content is 10%-50%, sugar content is 2%- 10%, also contains...
