On-situ utilization method of tobacco insect-killing and mould-proof agent

[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 end. Use a suction fan to extract the air in the stack through the above-mentioned holes until the composite film sticks to the stack of tobacco leaves. It is better to stick to it, but do not over-extract, so as to avoid excessive negative pressure and damage the composite film. Seal above-mentioned hole with heat sealing plastic sealing machine, then insecticide antifungal agent throws in and tobacco leaf seals up and finishes. After the storage is completed, regular inspections should be carried out. If it is found that the stacked composite film loosens quickly, or the water vapor disappears slowly on the top of the pile, or the insecticide and antifungal agent turns yellow quickly, it means that the composite film is damaged, and an appropriate amount should be added. Insecticide and antifungal agent for tobacco leaves, and then sealed.

[0027] The components and weight percentages of the tobacco leaf insecticide and antifungal agent are: 62.5% of 100 mesh pyrite powder, 12.5% ​​of perlite powder, 2.1% of charcoal powder, 4.2% of sodium chloride, 0.75% of sodium sulfite and 17.95% of water %.

[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 to avoid excessive negative pressure and damage the composite film. Seal the hole with a heat-sealing plastic sealing machine, and then the tobacco leaves insecticide and antifungal agent are thrown in and the tobacco leaves are sealed. Regular inspections should be carried out after the storage is completed. If it is found that the stacked composite film loosens quickly or the water vapor disappears slowly on the top of the pile, or the tobacco leaf insecticide and antifungal agent turns yellow quickly and completely, it means that the composite film is damaged, and an appropriate amount should be added Tobacco leaf insecticide and antifungal agent, and then sealed.

[0030] The components and weight percentages of the insecticide and antifungal agent for tobacco leaves are: 57.9% of 120-mesh reduced iron powder, 16.8% of perlite powder, 0.42% of copper sulfate, 4.2% of sodium chloride, 0.21% of sodium sulfite and 20.69% of water .

[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 leaves, but do not over-extract to avoid excessive negative pressure and damage the composite film. Seal the hole with a heat-sealing plastic sealing machine, and then the tobacco leaves insecticide and antifungal agent are thrown in and the tobacco leaves are sealed. Regular inspections should be carried out after the storage is completed. If it is found that the stacked composite film loosens quickly or the water vapor disappears slowly on the top of the pile, or the tobacco leaf insecticide and antifungal agent turns yellow quickly and completely, it means that the composite film is damaged, and an appropriate amount should be added Tobacco leaf insecticide and antifungal agent, and then sealed.

[0033] The composition and weight percentage of the insecticide and fungicide for tobacco leaves are: 78.6% of 80-mesh reduced iron powder, 6.7% of perlite powder, 0.22% of copper sulfate, 3.4% of sodium sulfate, 0.67% of sodium sulfite and 10.41% of water.
