Problems solved by technology

Using ultraviolet disinfection method, there is no experimental data and information to prove that what wavelength and how long to use can effectively kill specific types of viruses, which brings difficulties to practical applications, and in the actual process, viruses may also exist in the residue of utensils. It can also exist in the dead corners of the utensils. Due to the short wavelength of the ultraviolet rays, they are not penetrating, so they can only sterilize the irradiated utensils or the surface of the residual juice, even if the ultraviolet rays can kill the mosaic virus. The virus can only be used in the laboratory and has no actual use value

Embodiment 1

[0018] Example 1: Application of Microwave Technology in the Prevention and Control of Tobacco Diseases and Insects in Tobacco Seedling Cultivation

[0019] ① Use all-water foamed polyurethane (cost about 28,000 yuan / ton), and use a temperature resistance above 160°C as a seedling tray (specification: about 160 plants per tray), and the recycling cycle is 3-6 years.

[0020] ② Disinfect and kill the seedling trays: Tobacco growers use the seedling trays to clean, and then use microwave assembly line equipment with a frequency of 900-2500MHz and an output power of 220V900-2500W to irradiate and disinfect the seedling trays for 5-10 minutes. Tobacco mosaic virus can be inactivated by disinfection for 5 minutes. The sterilized seedling trays are directly used for seedling cultivation.

[0021] ③ Disinfection and elimination of leaf shears, leaf pinchers, and root cutters: use engineering plastics that can withstand high temperatures above 200°C and have good physical properties ...

Embodiment 2

[0023] Example 2: Application of Microwave Technology in the Prevention and Control of Tobacco Pests and Diseases in Tobacco Planting

[0024] Use a backpack-type mobile microwave device with a microwave frequency of 500-1500MHz and an output power of 200-1000W. Add an ultraviolet device with a wavelength of 254nm and a power of 30-100W to irradiate the tobacco plants for 5-20 seconds, which can effectively inactivate, reduce and inhibit the diseases on the surface of the tobacco plants, especially for the control of pests such as budworms. Reduce the transmission of tobacco mosaic virus through the mouthparts of pests.

Embodiment 3

[0025] Example 3: Application of microwave technology in preventing and controlling tobacco diseases and insect pests in tobacco curing and conditioning

[0026] The use of microwaves has the characteristics of internal heating and high heating efficiency. It is used to transform existing curing rooms or build new curing rooms. While curing tobacco leaves, it can kill tobacco viruses and reduce the subsequent spread of tobacco viruses. According to the area of ​​the barn, microwave devices are generally configured at 915MHz and 500-1000W per cubic meter. Use a microwave device with a frequency of 900-2500MHz and an output power of 900-2500W. The microwave irradiation disinfection time is determined according to the yellowing stage, color fixing stage and gluten drying stage of the current baking process, and is determined according to the quality and variety of tobacco leaves. The baking and tempering method is energy-saving, environmentally friendly and non-toxic, and can ina...

Abstract

The invention relates to application of a microwave technology in control on disease and insect damage to tobacco. By using the microwave technology to control the disease and insect damage to tobacco, the invention can effectively control the disease and insect damage to tobacco, especially tobacco mosaic virus diseases, in the aspects of tobacco seedling raising, tobacco planting, tobacco baking and seasoning, tobacco planting soil, tobacco storage and the like, and achieves better disease and insect damage control effect. Besides, the invention can not generate pesticide residue and environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of preventing and controlling tobacco diseases and insect pests, in particular to the technical field of using microwave technology to prevent and control tobacco diseases and insect pests. Background technique [0002] Tobacco pest control is a major issue in the development of tobacco agriculture. China has found that the diseases in tobacco planting mainly include 29 kinds of fungi, 16 kinds of viruses, 8 kinds of bacteria, 2 kinds of phytoplasma, 3 kinds of nematodes and 2 kinds of parasitic seed plants; the main pests are cutworms, needleworms, mole crickets, Aphids, tobacco budworms, stink bugs, thrips tabaci, tobacco leaf miners, tobacco stem moths, snails, wild slugs, etc. Tobacco leaf storage pests mainly include tobacco beetle, rice beetle, red beetle, tobacco powder moth, rice moth, flax moth, mole cricket, needleworm, cutworm, scarab, etc. Among them, tobacco beetle and tobacco powder borer are ...
