Chlorine dioxide for soil disinfection.
1. The principle of chlorine dioxide disinfection of soil.
Chlorine dioxide is a strong oxidizing agent, which has the characteristics of broad spectrum, high efficiency, fast acting and long-lasting. When chlorine dioxide reacts with organic matter in the soil, it can oxidize and decompose organic matter and release chlorine atoms, thereby destroying the enzymes and structures in the pathogenic bacteria to achieve the effect of sterilization and insect control. In addition, chlorine dioxide can also oxidize iron, manganese, sulfur and other elements in the soil to form insoluble precipitates, thereby improving the physical and chemical properties of the soil and improving the fertility of the soil.
Second, the role of chlorine dioxide in disinfection of soil.
1.Sterilization and disinfection: Chlorine dioxide can kill pathogenic bacteria, viruses, bacteria and other microorganisms in the soil, and effectively prevent and reduce the occurrence of plant diseases.
2.Improve soil environment: Chlorine dioxide can oxidize organic matter and heavy metal elements in soil, reduce soil pollution, improve soil physical and chemical properties, and improve soil fertility.
3.Promote plant growth: Chlorine dioxide can stimulate the development of plant roots, improve the ability of plants to absorb water and nutrients, promote plant growth, and improve the yield and quality of crops.
3. Methods for chlorine dioxide disinfection of soil.
1.Application time: Chlorine dioxide is applied before sowing or transplanting, which can effectively prevent and mitigate the occurrence of plant diseases. At the same time, chlorine dioxide can also be applied at the right time during plant growth to improve the plant's disease resistance.
2.How to use: Mix chlorine dioxide with an appropriate amount of organic fertilizer or fine soil, and spread it on the soil surface or around plant roots. Generally, about 500 grams of chlorine dioxide per mu are applied, which can be increased or decreased according to the actual situation.
3.Precautions: When using chlorine dioxide to disinfect soil, care should be taken not to mix it with alkaline and acidic substances to avoid chemical reactions and reduce the efficacy. At the same time, attention should be paid to the safe use of pesticides to avoid harm to people, animals and the environment.
IV. Conclusions. Chlorine dioxide disinfection of soil is an efficient, environmentally friendly and safe disinfection method. By using chlorine dioxide to disinfect the soil, it can not only kill pathogenic bacteria and microorganisms in the soil, prevent and reduce the occurrence of plant diseases, but also improve the soil environment, improve soil fertility, promote plant growth, and improve the yield and quality of crops. Therefore, it is recommended that farmers pay attention to choosing chlorine dioxide products produced by regular manufacturers when using chlorine dioxide to disinfect soil, and operate in accordance with the instructions to avoid harm to people, animals and the environment. At the same time, safety precautions should also be taken during use to avoid accidents.
