Problems solved by technology

There are several obvious defects in phosphine insecticide: First, tobacco leaves have been processed into a 200kg box of laminar tobacco before alcoholization, and the boxes are independent and sealed from each other, so it is difficult for phosphine gas to diffuse naturally It is in full contact with tobacco leaves, so there is the problem of incomplete insecticide; the second is that phosphine is a highly toxic substance. After contacting tobacco leaves, the phosphine remaining in tobacco leaves will cause certain dama

Example Embodiment

[0025] Example 1

[0026] Lay a plastic cloth base film on the floor of the tobacco warehouse, spread a PA / PE composite film bottom cover on the bottom film, stack tobacco leaves layer by layer on the composite film bottom cover, and lay a layer on the top of the stack of tobacco leaves The top film of plastic cloth is used for putting the tobacco leaf insecticide and antifungal agent and waterproofing, and puts 1.4 kg of tobacco leaf insecticide and antimold agent per cubic meter of tobacco leaves on the stack top film. Tobacco leaf insecticide and antifungal agent should be put in as soon as possible to prevent it from being oxidized due to long-term contact with air and reduce the use effect of tobacco leaf insecticide and antifungal agent; it should be evenly spread, and after putting in, quickly and carefully cover the PA / PE compound For the membrane top cover, use a plastic sealing machine to heat seal the bottom cover and the top cover together, leaving a hole at the en...

[0028] Example 2

[0029] Lay an asphalt base film on the floor of the tobacco warehouse, lay a PA / PE composite film bottom cover on the bottom film, stack tobacco leaves layer by layer on the composite film bottom cover, and lay a layer of linoleum on the top of the stack of tobacco leaves The top film is used for dispensing tobacco leaf insecticide and antifungal agent and waterproofing. Throw in 3.5 kilograms of tobacco insecticide and antifungal agents per cubic meter of tobacco leaves on the stack top film. Tobacco leaf insecticide and antifungal agents should be put in quickly and spread evenly. After putting in, quickly and carefully cover the top cover of PA / PE composite film, heat seal the bottom cover and the top cover together with a plastic sealing machine, and leave a gap at the end. hole. Use a suction fan to extract the air in the stack through the above-mentioned holes until the composite film is close to the stack of tobacco leaves, but do not over-extract t...

[0031] Example 3

[0032] Lay the old tarpaulin bottom film on the floor of the tobacco warehouse, and spread the bottom cover of PA / PE composite film on the bottom film, stack the tobacco leaves layer by layer on the bottom cover of the composite film, and lay a layer on the top of the stack of tobacco leaves. A layer of old tarpaulin top film is used for putting insecticide and antifungal agent and waterproofing, and 2.5 kg of tobacco leaf insecticide and antimold agent are put in per cubic meter of tobacco leaves on the stacked top film. Tobacco leaf insecticide and antifungal agents should be put in quickly and spread evenly. After putting in, quickly and carefully cover the top cover of PA / PE composite film, heat seal the bottom cover and the top cover together with a plastic sealing machine, and leave a gap at the end. hole. Use a suction fan to extract the air in the stack through the above-mentioned holes until the composite film is close to the stack of tobacco leave...

Abstract

An application of the insecticide-anti-mildew agent in tabacco leaves includes such steps as spreading bottom film on the floor of tobacco leaf storehouse, spreading a lower sleeve of a composite plastic sleeve, stacking tobacco leaves, spreading a top film, applying said insecticide-anti-mildew agent, covering with an upper sleeve, thermally sealing the composite plastic sleeve, vacuumizing via a hole until the plastic film is tightly close to tobacco leaves, and sealing the hole.

Description

technical field [0001] The invention relates to the field of tobacco leaf insecticidal and antifungal agents, in particular to a field application method of tobacco leaf insecticidal and antifungal agents. Background technique [0002] After the tobacco leaves are harvested and baked, in order to remove the green smell and reduce the irritation of the tobacco leaves, improve the aroma quality, reconcile the chemical components, and improve the flammability and smoking quality of the tobacco leaves, the flue-cured tobacco must be alcoholized or fermented before it can be used to produce cigarettes. [0003] At present, the aging methods of domestic tobacco leaves (including tobacco and sheet tobacco) basically adopt natural aging, but the following phenomena are easy to occur during the natural aging process: first, insects; second, mildew; third, long-term and excessive tobacco leaves When exposed to air, the color of tobacco leaves is easily browned and darkened. Due to th...
