Embodiment 1
[0023] (1) Pretreatment of gibberellin fermentation residue: Take 100kg of gibberellin fermentation residue, add 23kg of rice straw powder with a particle size not greater than 0.6mm, 42kg of tap water, and add 0.3% Angel brand active dry yeast (strain Purchased from Yichang, Hubei, Hubei Angel Yeast Co., Ltd.), mixed evenly and put into the fermentation tank. After inoculation, the fermentation raw materials were sealed with plastic film for anaerobic fermentation. After 5 days, the plastic film covering the fermentation raw materials was uncovered , that is, the pretreatment of the gibberellin fermentation residue is completed to obtain the compost of fly maggots.
[0024] (2) Fly maggot treatment of gibberellin fermentation residue: in the maggot raising room, the treated gibberellin fermentation residue is divided into plastic boxes of 6kg / box (for example, the size of the plastic box is 60cm *40cm), each plastic box was inoculated with housefly eggs

Embodiment 2
[0039] (1) Pretreatment of gibberellin fermentation residue: Take 100kg of gibberellin fermentation residue, add 10kg of rice straw powder with a particle size not greater than 0.6mm, add 18kg of tap water, and add 0.5% of Hubei Angel Yeast Co., Ltd. Angel brand active fermented dry yeast, mixed evenly, put into the fermentation tank, sealed with a plastic film for fermentation, uncovered the plastic film after 5 days, and obtained fly maggot culture material;
[0040] (2) Fly maggot treatment gibberellin fermentation residue: In the maggot culture room, the obtained fly maggot culture material is divided into 60cm*40cm plastic boxes at a rate of 5kg / box, and each box is inoculated with 18g of housefly eggs for breeding During the cultivation process, the temperature is controlled at 24°C-29°C. After 6 days, live fly maggots and treated fermentation residues are separated.
[0041] (3) The obtained live fly maggots are directly used for protein feeding of poultry animals such ...
Embodiment 3
[0044] (1) Pretreatment of gibberellin fermentation residue: get 100kg of gibberellin fermentation residue, add 15kg of corn stalk powder with a particle size not greater than 0.6mm, add 28kg of tap water, and insert 0.4% saccharomyces (Angelica yeast, Angel Yeast Co., Ltd., Yichang, Hubei), put it into the fermentation tank after mixing evenly, seal the fermentation tank with a plastic film, uncover the plastic film after 5 days, and obtain the fly maggot culture material;
[0045] (2) fly maggots handle gibberellin fermentation residue: in the maggot raising room, the fly maggot culture material will be obtained by 6kg / box, sub-packed in plastic boxes of 60cm*40cm, and each box is inoculated with 15g of housefly ovum for cultivation. During the breeding process, the temperature is controlled at 20-28° C., and after 5 days, the fly maggots and the treated fermentation residue are separated.
[0046] (3) Preparation of insect protein: the separated fly maggots were dried at 80...
