1、 Introduction to Ozone
Ozone (O) is an oxygen isotope composed of three oxygen atoms, with a unique pungent odor. At room temperature, ozone appears as a light blue gas. Due to the weak binding of the third oxygen atom of ozone, it is highly unstable and easily decomposes at room temperature to produce atomic oxygen with strong oxidizing ability, thus possessing strong sterilization and disinfection functions. Ozone is unstable and easily decomposes into oxygen. Its half-life in air is generally 20-50 minutes, and the higher the temperature and humidity, the faster the decomposition. The decomposition rate of ozone in water is faster than in air, and its half-life mainly depends on water quality and temperature. In recent years, the trend of using ozone in greenhouse cultivation of fruits and vegetables has been increasing, and more and more enterprises are choosing to use ozone.
2、 The mechanism of ozone sterilization
Ozone has strong oxidizing properties, with its oxidation-reduction potential second only to fluorine. It has strong oxidizing ability and therefore has a strong killing effect on bacteria, fungi, and viruses. Ozone first acts on the cell membrane, causing damage to its constituent components and leading to metabolic disorders. Ozone continues to penetrate through the membrane, destroying lipoproteins and lipopolysaccharides inside, altering cell permeability, and causing cell lysis and death; Meanwhile, ozone can also inactivate enzymes necessary for cellular activity, thereby affecting their normal physiological functions. Ozone sterilization can not only directly treat substances with ozone gas, but also dissolve them in water to form ozone water for sterilization.
3、 Advantages of ozone sterilization and pest control
1. Safe, efficient, and cost-effective. Ozone can be used for multiple purposes, while also preventing and controlling various pests and diseases, and the cost of prevention and control is low. Compared with spraying pesticides, releasing ozone is more convenient, efficient, and safe, which can greatly reduce the amount of pesticide used, avoid vegetable farmers from using highly toxic and residual pesticides, and thus reduce medication costs.
2. Non polluting. Ozone is unstable in the air and can quickly decompose and reduce to oxygen. Therefore, it is an important way to achieve pollution-free and residue free vegetable production in plants and fruits.
3. Improve quality and increase production. The method of generating ozone through high-frequency and high-voltage discharge from an air source not only produces the ozone I need, but also produces nitrogen oxides, which can be used as nitrogen fertilizer for plants. There is experimental evidence that the use of ozone in greenhouse tomatoes significantly reduces abnormal fruit, increases yield by about 20%, and results in larger fruit size, better coloring, and better taste.
4、 YT-5300-20/P type ozone generator for fruit and vegetable greenhouses
This series of products adopts manual operation or fully automatic unmanned operation mode, which can directly sterilize and disinfect the space inside the greenhouse or selectively distribute pipes to designated spaces for sterilization and disinfection. It can also be moved for operation as needed, effectively killing bacteria, fungi, viruses in the space, preventing cross infection of diseases, etc., while not producing harmful residues, and avoiding secondary pollution. It can play a crucial role in the production of fruits and vegetables in greenhouses and the cultivation of various organic vegetables and fruits.
1、 Purpose:
Ozone gas is used for sterilization and disinfection of greenhouse space, which can effectively remove bacteria, fungi, viruses, etc. inside the greenhouse.
Ozone gas mixed into water can be used for sterilization of plant seed surfaces
Ozone gas can be used for sterilization and disinfection in horticultural flower cultivation, reducing the incidence of various flower diseases.
4. Fumigation and disinfection: 10 days before planting, ozone can be concentrated in the greenhouse using an ozone generator in combination with high-temperature confinement. The recommended application time is 2-3 hours.
5. Prevention and control of diseases and pests in seedbeds: First, seal the seedbed tightly, apply for 1 minute every 10 square meters, and fumigate it tightly for 10 minutes, then ventilate for 30 minutes.
6. Disease and pest control after vegetable planting: After planting and delaying seedlings, the greenhouse should be turned on every 2-3 days every 1000m3 for 60 minutes each time.
Ozone water can be used to prevent and control pests and diseases in the soil.
2、 Scope of application
Diseases applicable to leafy vegetables: frost rot, soft rot, viral disease, black rot, black spot disease, leaf spot disease, gray mold disease, spot disease, leaf spot disease, sclerotic disease, stem rot disease, clubroot disease, snake eye disease, spot disease, black root disease, white rust disease, wheel spot disease, dry burning heart disease, etc.
Leaf vegetables use pests such as aphids, whiteflies, as well as cabbage caterpillar eggs and diamondback moth eggs.
Diseases applicable to eggplants and fruits: cotton rot disease, soft rot disease, viral disease, black spot disease, leaf spot disease, spot disease, leaf spot disease, vertical blight disease, early blight disease, late blight disease, anthracnose disease, brown spot disease, brown streak disease, bacterial brown spot disease, etc.
Suitable pests for eggplants and fruits: tarsal mites, whiteflies, aphids, cotton bollworm eggs, and tobacco caterpillar eggs.
Diseases applicable to melons and fruits: gray mold, phytophthora root rot, sclerotinia rot, early blight, late blight, Fusarium wilt, Verticillium wilt, damping off, angular spot disease, viral disease, nematode disease, mosaic disease, etc.
Insects suitable for fruits and melons: aphids, whiteflies, spider mites, etc.
3、 Installation and usage instructions
1. Install the ozone generator in the designated location or move it to the disinfection site, align the outlet of the ozone generator with the disinfection work space or connect it to the designed and installed disinfection pipeline system. Ensure that the casing is well grounded, power on, and select manual or automatic switch operation mode. If automatic operation is selected, set the time process according to the instructions, and the ozone generator will disinfect according to the set time process.
Before planting, combine with high-temperature greenhouse and turn on the ozone generator for 2-3 hours. After planting, turn on the machine 3-4 times a week for 1 hour each time.

5、 Precautions for Ozone Use
Reasonably determine the amount of application and fumigation time. When releasing, it should be as uniform as possible, and the nozzle should not directly face the vegetables. It should be at least 0.8-1 meters away from the vegetable plants. After the fumigation time, ventilation should be carried out promptly, and the general ventilation time should not be less than 30 minutes.
Temperature and humidity regulation. When ozone is released, the indoor temperature of the greenhouse should be maintained within the range of 10-30 ℃, and the prevention and control effect will be better under high air humidity& lt;
