The application of ozone in vegetable farming
In vegetable farming, ozone has the following applications:
1. Sterilization and disinfection: It can effectively kill harmful microorganisms such as bacteria, fungi, viruses, etc., reduce the occurrence of diseases and pests, and reduce the use of pesticides.
2. Purifying the environment: Helps to decompose odors in the air and improve the air quality of vegetable planting environments.
3. Promoting growth: To a certain extent, it may have a stimulating effect on the growth of vegetables, promote metabolism, and improve the vitality and quality of vegetables.
4. Degradation of pesticide residues: It has a certain degradation effect on some pesticide residues and improves the safety of vegetables.
The following are some common usage methods of ozone in vegetable cultivation:
1. Air disinfection: Ozone is released into the air of vegetable planting areas through an ozone generator to disinfect the air and reduce the spread of bacteria in the air.
2. Water disinfection: Ozone is introduced into water to produce ozone water, which can be used for vegetable irrigation or spraying, playing a role in disinfecting water and vegetable surfaces.
3. Ozone fumigation: During a specific time period, the vegetable planting space is enclosed and subjected to a certain period of ozone fumigation to kill bacteria and insects.
4. Combined with irrigation system: Connect ozone with the irrigation system, so that ozone is evenly distributed to the roots of vegetables and surrounding soil with the irrigation water.
Ozone usage concentration
The concentration of ozone in vegetable cultivation needs to be adjusted according to specific circumstances. Generally speaking, a high concentration of ozone may have adverse effects on vegetables, while a low concentration may not achieve the expected control effect.
In practical applications, the concentration of ozone is usually between 0.2-0.4 milligrams per liter. But the specific concentration also needs to consider the following factors:
-Vegetable types: The tolerance of different vegetables to ozone may vary. Some vegetables may be sensitive to ozone and require lower concentrations, while some vegetables with stronger tolerance may be able to withstand higher concentrations.
-Disease type: Different diseases may also have different sensitivities to ozone. When preventing and controlling specific diseases, it is necessary to adjust the concentration based on the characteristics of the disease and the killing effect of ozone.
-Environmental conditions: Environmental conditions such as temperature and humidity can also affect the effectiveness of ozone. Under different environmental conditions, it may be necessary to adjust the concentration of ozone appropriately.
When using ozone for vegetable cultivation, it is recommended to conduct small-scale experiments first to determine the appropriate ozone concentration and usage method. At the same time, attention should be paid to the safety of ozone use to avoid harm to human health and the environment.
When using ozone in vegetable farming, attention should be paid to the following issues:
-Reasonably determine the application amount and fumigation time: The application amount and fumigation time of ozone should be adjusted appropriately according to different crops and their growth stages. Crops in the mature stage have a stronger adaptability to ozone, and as the plant grows, the application amount and fumigation time can gradually increase. In practical operation, it is necessary to ensure that ozone is evenly distributed, and the nozzle should be at least 0.8-1 meters away from vegetable plants. After fumigation, it is necessary to ventilate in a timely manner for no less than 30 minutes.
-Temperature and humidity control: When ozone is applied, the temperature inside the greenhouse should be maintained within the range of 10-30 ℃. In cases of high air humidity, the prevention and control effect will be better.
-Use a suitable power source: The ozone generator usually uses lighting electricity.
In addition, when using ozone to prevent vegetable diseases, attention should be paid to the concentration of ozone to avoid damage to vegetables caused by excessive concentration. At the same time, attention should be paid to the safety of operators to avoid ozone leakage causing harm to the human body.
