Problems solved by technology

[0004] At present, various tobacco growing areas mainly adopt the method of centralized landfill and retting to deal with unsuitable fresh tobacco leaves. However, this technology has a long treatment cycle and produces a large amount of waste gas, waste residue and waste liquid during the period. The follow-up treatment is difficult and seriously pollutes the local agricultural ecology. Environment and Residents' Physical and Mental Health

Embodiment 1

[0036] S1. Use a grass cutter to crush unsuitable fresh tobacco leaves to a particle size of 3 to 5 cm, and place the crushed unsuitable fresh tobacco leaves directly in a homogenizer for homogenization for 5 to 10 minutes to obtain a homogenate;

[0037] S2. Add bran powder, butyl p-hydroxybenzoate, potassium sorbate and agar powder to the inapplicable fresh tobacco leaf homogenate described in S1, and stir to obtain a mixture;

[0038] The formula is: not applicable fresh tobacco leaf homogenate 85% + bran powder 13% + butyl p-hydroxybenzoate 0.2% + potassium sorbate 0.2% + agar powder 1.6%. Wherein, the bran is crushed and passed through a 120-mesh sieve. Butyl p-hydroxybenzoate, potassium sorbate and agar powder are all food grade, and they are routinely purchased in food additive companies or retail stores.

[0039] S3. Slowly heat the mixture obtained in S2 to 60°C with low heat, and keep stirring while heating to obtain a hot mixture;

[0040] S4. Pour the hot mixture...

Abstract

The invention discloses a method for biological treatment of unavailable fresh tobacco leaves by utilizing spodoptera litura, and a material formula. According to the method disclosed by the invention, the unavailable fresh tobacco leaves are creatively utilized for appropriate treatment, then appropriate compatible components are added to prepare a semi-artificial feed for feeding the spodoptera litura till the the larval development stage is completed, then the unavailable fresh tobacco leaves are completely treated, output products are mature larvae and frass of the spodoptera litura, the mature larvae of the spodoptera litura can be used as a high-quality insect protein feed after drying, and the frass can be used as a high-quality organic fertilizer after aerobic composting. The method disclosed by the invention has the advantages that the treatment capacity of the unavailable fresh tobacco leaves is great, the treatment cost is low, the period is short, the treatment of the unavailable fresh tobacco leaves is complete, the reduction effect is obvious, and the production of waste residue, waste gas, waste liquid and other secondary pollution in treatment process is avoided; products after the treatment are insect protein powder and the frass organic fertilizer of the spodoptera litura, and the economic benefits of a treatment plant can be increased.

Description

technical field [0001] The invention relates to the technical fields of the tobacco industry and biological environmental protection, and more particularly relates to a method and a material formula for biologically treating unsuitable fresh tobacco leaves with Spodoptera litura. Background technique [0002] Not Applicable Fresh tobacco leaves refer to the bottom two tobacco leaves (not including the two tire leaves) that are insufficiently illuminated, stunted, have many lesions, the length does not meet the requirements, and the quality is poor after baking; stunted, poorly opened , less than 35cm in length, more diseased spots, and a piece of top leaf with poor quality after roasting is low-grade tobacco leaves, upper tobacco leaves, etc. Once the unapplicable tobacco leaves enter the barn, it will not only cause unnecessary waste of tobacco farmers for tobacco weaving, furnace loading, curing, grading and fuel, and increase ineffective investment, but also cause low-gr...
