Fog fog dual-use machine is a very advanced agricultural machinery, widely used in agriculture, forestry, animal husbandry, urban sanitation, large-scale epidemic prevention and public places worm disinfection. In order to improve the utilization ratio of agricultural machinery and reduce the operating cost, agricultural machinery should be widely used and highly comprehensive utilization under the premise of ensuring agricultural technical requirements. Mist machine is easy to carry, the environment is very wide, high efficiency, medication, low cost, good diffuse, high adhesion, beautiful and simple, lightweight, smooth lines, easy to operate. Using the characteristics of forestry trees: (1) drugs and small pollution because of drug particle size effect fully, greatly reducing the pesticide input, less water, so to adapt to the mountains, hills and plateau water area. (2) insecticidal sterilization rate is high: the mist smoke machine special agent of the company specializing in the development of diffusion has insecticidal very good sterilizing effect, the diffusion agent has strong adhesion capability and anti rain erosion, weathering resistance, diffusion characteristics of large area etc.. Such as: can use the fruit rot, canker, pear scab, anthracnose, aphids moth and whitefly, Botrytis cinerea and downy mildew, early blight, late blight, cotton bollworm, fleahopper, red spider, and is suitable for use with a variety of pesticides (the ratio of foliar fertilizer, pesticides, sterilization powder etc.). (3) raise the temperature: in the spring crop germination, the smoke spraying has to improve the surface temperature to prevent the increase and increase the cost of frozen flowers. (4) high range, far: flat spray area, jet smoke up to more than 50 meters. The liquid and small particles, strong penetration, suitable for high density bar and large plants such as tea plantations, forest, fruit, late wheat, cotton and maize, rice etc.. (5) the city health and epidemic prevention and sanitation and transportation for hotels, parks, residential property, city underground road, garbage dump, toilet, container, warehouse etc. in addition to the "four pests". The utility model is used for disinfection and sterilization of vehicles such as stations, docks, passenger ships, trains, automobiles, planes, etc..
