Embodiment 1
[0044] After the fresh unsuitable tobacco leaves are cleared from the tobacco field, crush the unsuitable tobacco leaves with a crusher to make the particle size reach 2mm, then add appropriate amount of nutritional auxiliary materials (see Table 1), stir evenly, and prepare compost. Pour the culture material into a plastic pot (length×width×height=80×60×20cm), the height of the culture material is 6cm, and insert an appropriate amount of housefly eggs on the surface of the culture material, and the egg density is: 0.5g housefly eggs / kg compost. At room temperature, the housefly eggs hatched into larvae on the 2nd day and began to decompose and transform the compost. After 5 days, the housefly larvae treated the compost to brown, the material was loose, and had no irritating smoke smell. After drying with hot air at 80°C, it could be made into biological protein feed.
[0045] The prepared biological protein feed has a crude protein content of 20.8%, a nicotine content of 0....
Embodiment 2
[0050] After the fresh unsuitable tobacco leaves are cleared from the tobacco field, the unsuitable tobacco leaves are crushed with a crusher to make the particle size reach 3mm, and then an appropriate amount of nutritional auxiliary materials (see Table 2) are added, stirred evenly, and prepared into a compost. Pour the culture material into a plastic pot (length×width×height=80×60×20cm), the height of the culture material is 7cm, and insert an appropriate amount of housefly eggs on the surface of the culture material, and the egg density is: 1.0g housefly eggs / kg compost. At room temperature, the housefly eggs hatched into larvae on the 2nd day and began to decompose and transform the compost. After 5 days, the housefly larvae treated the compost to brown, the material was loose, and had no irritating smoke smell. After drying with hot air at 100°C, it could be made into biological protein feed.

Embodiment 3
[0057] After clearing the fresh unsuitable tobacco leaves from the tobacco field, crush the unsuitable tobacco leaves with a crusher to make the particle size reach 4mm, then add appropriate amount of nutritional auxiliary materials (see Table 3), stir evenly, and prepare compost. Pour the culture material into a plastic pot (length×width×height=80×60×20cm), the height of the culture material is 8cm, and insert an appropriate amount of housefly eggs on the surface of the culture material. The egg density is: 1.2g housefly eggs / kg compost. At room temperature, the housefly eggs hatched into larvae on the 2nd day and began to decompose and transform the compost. After 5 days, the housefly larvae treated the compost to brown, the material was loose, and had no irritating smoke smell. After drying with hot air at 80°C, it could be made into biological protein feed.
