Embodiment 1

[0044] 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 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 0.1%,...

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 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 4mm, and then an appropriate amount of nutritional auxiliary materials (see Table 3) 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 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.

Abstract

The invention discloses a method for processing inapplicable tobacco leaves by musca domestica larvae to prepare a biological protein feed, and belongs to the technical field of environmental protection. The method for processing the inapplicable tobacco leaves by the musca domestica larvae to prepare the biological protein feed comprises the steps of: crushing fresh inapplicable tobacco leaves until the grain size of the crushed leaves is 1-5mm; adding bran, mixture of rice chaff and husk, feather meal and spray-dried animal blood cells to prepare compost; and inoculating housefly eggs at the surface of the compost, cultivating the housefly eggs for 5 days at 25-35 DEG C, collecting the compost containing the musca domestica larvae, drying and preparing the biological protein feed. The method disclosed by the invention is strong in handling capacity, small in floor area, and low in energy consumption in the processing process, achieves the resource utilization of the inapplicable tobacco leaves, changes waste into precious resources, improves the environmental health, simultaneously produces the biologic protein feed, and has a good application prospect.

Description

technical field [0001] The invention relates to a method for treating unsuitable tobacco leaves, in particular to a method for preparing biological protein feed by treating unsuitable tobacco leaves with housefly larvae. Background technique [0002] China's tobacco planting area and output both rank first in the world. With the continuous development of China's cigarette industry and the increasing pursuit of high-quality cigarettes by smokers, more and more attention has been paid to middle and upper-grade tobacco leaves, while a large number of unsuitable tobacco leaves have been discarded. Unsuitable tobacco leaves refer to fresh tobacco leaves (80-90% moisture content) that are not suitable for flue-cured tobacco production, which are different from the waste or low-grade tobacco leaves (moisture content about 15%) produced during the flue-cured tobacco production process that are widely mentioned in the literature . If these unsuitable tobacco leaves are randomly dis...
