Nowadays, people are paying more and more attention to green planting and are willing to buy some green fruits and vegetables. The issue of pesticide residues in vegetables has become a hot topic of concern for people today. Faced with the harassment of pests, farmers use pesticides, which leads to a decline in the quality of fruits and vegetables, affecting food and sales.

With the advancement of technology, fruits and vegetables are no longer single season products as they used to be. Nowadays, people can eat fresh vegetables and fruits all year round. When there is a market demand for the establishment of fruit and vegetable greenhouses, there are also many problems in the growth process of greenhouse vegetables and fruits because the temperature and humidity inside the greenhouse are high, and there are more pests than agricultural products grown in the fields. This is a headache for the staff of the greenhouse planting base. Pest control in agricultural greenhouses is an important factor affecting quality. Due to the fact that greenhouses often remain stationary for many years after construction, crop rotation is difficult, resulting in the accumulation of various raw materials in the soil year by year; The greenhouse is warm, with high humidity, and many insects can reproduce year-round and pose a threat; The large temperature difference between day and night leads to the formation of dewdrops on the surface during nighttime cooling, and the long-term unreasonable use of pesticides.

Because ozone has unstable properties and strong oxidizing ability. Ozone can degrade large molecules of organic matter into small molecules, serving the purpose of sterilizing residual pesticides and purifying the air. Ozone emissions in vegetable greenhouses can kill insects and have a strong degradation effect on pesticides when the concentration reaches a certain level. In the process of greenhouse vegetable cultivation, the care of vegetables is very important. The seeds purchased from the market are likely to contain bacteria and insect eggs. Ozone gas from an ozone generator can be introduced into clean water. Generally, ozone solution, also known as ozone water, can be prepared by passing ozone for 10 minutes. Soak the seeds in it for 15-20 minutes to kill the eggs on the surface of the seeds. If the greenhouse is regularly fumigated and sterilized, an ozone generator can be used to concentrate ozone inside the greenhouse, which can kill pests, eggs, and other pests on the surface and roots of vegetables. The recommended release time is 10 minutes. Before planting in the greenhouse, it can be continuously applied for 2 hours. When the agricultural greenhouse insecticide ozone sterilizer is turned on, the indoor temperature of the greenhouse should be maintained within the range of 10-30 degrees. Using an ozone generator will have better results in high air humidity. Ozone sterilizer can be used to sterilize insecticidal eggs in agricultural greenhouses.
