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

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...

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 damage to the body of smokers.

Spraying antifungal agents is difficult to spray evenly and comprehensively, so the effect is limited, and it is also difficult to avoid the impact of antifungal agents on the environment and people; the temperature control and humidity control method has high requirements for the warehouse, requiring a large number of temperature and humidity adjustment equipment. It needs to consume a lot of power, has the disadvantages of poor effect, inconvenient use, large investment, and high operating cost.
