Friends, talk about whether the smoke machine works or not. What are the advantages and disadvantages?

Sprayers are a good helper for modern agriculture. In daily agricultural work, in order to get a better harvest in autumn, it is necessary to spray pesticides and insects on crops from time to time. With the development of modern agriculture, the planting area will be more inclined to the development of large and medium-sized farms, so it is necessary to use more efficient sprayers. 1, saving time and labor: when spraying medicine, the spraying machine only needs 7 10 minutes per mu, which greatly reduces the labor intensity and avoids the inconvenience of the old medicine pump, such as large water demand, long medicine tube and multi-person operation; 2. The mist particles of the long-acting pesticide sprayer are extremely fine (up to 0.5 micron), which enhances the adhesive force of pesticides, makes the application surface uniform, improves the efficacy, and improves the insecticidal and bactericidal properties; 3. Improve the quality of fruit: the atomized pesticide sprayed by atomizer is very fine, which has no stimulation to the surface of fruit, and the surface of fruit is bright, and there are many high-grade fruits, which can reduce the drug residue; Mr. Four. Protect your health: it is best to spray medicine in the morning and evening when there is no wind/breeze, so as to avoid the phenomenon that the old medicine pump must spray medicine on a hot day and people are prone to sweating and poisoning; 5. Warming up to prevent freezing: When fruit trees germinate and bloom in spring, after adding aerosol, spraying smoke can raise the temperature to prevent frozen flowers and fruits and reduce losses; 6. Wide coverage and no dead angle: The atomizer can achieve the effects of strong penetration, high comprehensive efficiency and no dead angle when killing insects and sterilizing. Disadvantages are high price and high maintenance cost.
