Air disinfection air disinfection technology, in line with the "prevention-oriented, comprehensive control" plant protection policy, the effect is outstanding, unique advantages. It is especially suitable for grey blast, downy mildew, leaf mold and other blasts that are highly volatile and mainly rely on airborne diseases. It only costs 4 ~ 5 yuan per mu per shed, no special equipment is required for use, only warm water and water cups are needed, which is more labor-saving and labor-saving compared with conventional control technology.
In general, about 30 tablets per acre of fumigation shed. When the ventilation is normal on a sunny day, the disease occurs less, and the shed can be smoked once a week. When it is cloudy, watering, or disease, it should be used more often, it can be used once every 2-3 days. When using, you can set a reaction point at about 10 meters (you can use a mineral water bottle), add 50 ml of warm water at 30 ~ 50 ℃, put in 4 ~ 6 pieces of air disinfection tablets, and you can see that the air disinfection tablets react with water quickly. A large number of air bubbles are generated, which play the role of air disinfection after diffusion.
Ozone sterilizer Ozone sterilizer has many advantages. Through the system setting, it works at night and disinfects twice, so that the fungus and bacteria in the shed can be eliminated in the air. Compared with aerosols with similar modes of action, the advantages of ozone sterilizers are as follows:
The first is that the ozone sterilizer is pollution-free, and the aerosol particles are large. After the aerosol is ignited, the dust particles slowly adhere to the crop leaves and fruit surfaces to play a corresponding role, which will cause pollution to the fruits.
The second is that ozone has a broad spectrum of sterilization and has a good killing effect on fungi and bacteria.
Third, the use of ozone sterilization machine is safe, labor-saving and time-saving. Once the ozone sterilizer system is set up, after hanging in the greenhouse, it only needs to be powered on to run, and after power failure, it can be started through the switch. The use method is simple Convenient, avoiding excessive dosage or untimely air release after the use of aerosol, which can cause plant damage.
In addition to doing a good job of air disinfection, attention should also be paid to strengthening the insulation, spreading straw, reducing the humidity in the shed, increasing the shed temperature, thereby reducing dew and avoiding the spread of pathogenic bacteria.
Hanging "it" vegetables in the shed in winter is less ill and less medication
