Electrolytic water (EW), also known as REDOX potential water and ionized water, is a functional water with a certain pH value, REDOX potential (ORP) and effective chlorine concentration (ACC) formed by electrolyte solutions such as sodium chloride solution under the action of electric field. The application of electrolytic water is a sustainable green concept with advantages over traditional cleaning systems such as cost effectiveness, ease of use, good disinfection results, on-site production, and safety for humans and the environment. According to P H value, it can be divided into strong acid electrolytic water AEW(P H value 2-3), slightly acidic electrolytic water SAEW (pH value 5.0-6.5), neutral electrolytic water NE W(pH value 7-8), slightly alkaline electrolytic water SAIEW (pH value 8-10). , strong alkaline water electrolysis AIEW (pH 10-13).
Electrolysis water has a broad application prospect in green prevention and control of crop diseases and pollution-free agricultural production, which is beneficial to enhance the ability of sustainable agricultural development, reduce the pressure of pesticide application on the environment and improve the quality of agricultural products. Luo Xinxi et al. used acid electrolytic water to control cucumber powdery mildew. The results showed that the acid electrolytic water with pH value of 2.0 had the best control effect, and the control efficiency reached 72.10%. The effective control period of acidic electrolytic water is 3 days after spraying. Spraying KC1 electrolytic water can not only replace pesticide to control cucumber powdery mildew, but also significantly improve cucumber fruit quality. The control effect of strong acid electrolytic water on gray mold of eggplant in field reached 68.71%, which could partly replace pesticide. Wang Buyun et al. sprayed acid electrolytic water continuously in the slow seedling stage of tomato, not only had a certain control effect on tomato leaf mildew, but also could increase the yield; Continuous spraying at the beginning of the disease also had a certain control effect on tomato leaf mildew, but the effect on yield was not obvious. Gu Peiyun et al. suggested that continuous spraying of acidic electrolytic water in the slow seedling stage and early onset of pepper had a good control effect on powdery mildew. Sun Hui et al. used acidic electrolytic water to pair horse bells
The production workshop and equipment of potato virus-free seedlings were sterilized, which could effectively improve the survival rate of stem tip, save costs, and be safe and environmental protection. In addition, electrolysis water is also effective in controlling fruit diseases such as grape downy mildew II, field crop diseases such as rice smut cutting, wheat scab, etc.
4.2 Promote growth and improve quality
Xin-hao gao et al. Study on the net, the different pH value of strongly acidic electrolysis of water soaked with influence on cucumber seed germination and seedling growth, the results show that appropriate concentration of strongly acidic electrolysis of water soaked with cucumber seed embryo growth rate can be improved and the quality of cucumber seedling, low and medium concentration electrolysis of water has no effect on cucumber seed germination rate, and high concentration of electrolysis of water showed inhibitory effect. Hou Mengshi et al. studied the effect of electrolytic water irrigation on Chinese cabbage. Acidic electrolytic water could promote the net photosynthetic rate of leaves to some extent. The accumulation of chlorophyll and the increase of leaves in Chinese cabbage were increased by acid electrolysis water under sprinkler irrigation and strong alkaline electrolysis water under root irrigation
The number of slices and the increase of yield could promote, but inhibit plant height. Alkaline electrolysis water by root irrigation can promote the content of vitamin C in Chinese cabbage. Cao Wei et al. soaked wheat seeds with slightly acidic electrolytic water and sprayed malt, which could effectively control the number of bacteria and fungi on the surface of malt-raising vegetables, increase the seedling height and content of reducing sugar and rutin, but had no effect on the yield and dry weight of sprouts.
4.3 Soil improvement
Acidic electrolytic water to adjust salinized soil, alkaline electrolytic water to adjust acidic soil, not only can effectively adjust the soil acid-base environment, but also without any residue, when using the stock solution or diluent irrigation adjustment, very convenient; The application of acid water can also kill part of soil-borne bacteria. Hu Yanfang found that the six treatments of acid electrolytic water and fertilizer could improve the forest soil properties to different degrees, and the number of soil microorganisms increased, the enzyme activity increased, and the chemical properties were improved. The biomass and juveniles of Pingyi sweet tea seedlings could be significantly increased by adding slightly acidic electrolytic water to apple continuous cropping soil
Seedling root length, root surface area, root volume and root respiration and oxygen consumption rate were all increased. Soil fungi constitute an independent community structure, which can adapt to the soil environment after water electrolysis treatment and become the dominant community, which can reduce the obstacles of continuous cropping.
4.4 Fruit and vegetable sterilization and preservation
Hao Jianxiong et al. soaked tomato with acidic electrolytic water for 10 min and stored at room temperature for 12 days, the fruit hardness was significantly increased, the respiratory intensity was significantly inhibited, and the weight loss rate was decreased compared with the control. Li Huazhen et al. soaked spinach with acidic electrolytic water, which could rapidly reduce the surface microorganism content. After 9 days of storage at 5 C, the microorganism increased slowly, the nutrient composition remained basically unchanged, and the accumulation of nitrite was inhibited. Huicheng Zhang et al. used neutral oxidized water and other disinfectants for sterilization of cabbage. The neutral oxidized water has high sterilization effect, and the effect is better than other disinfectants. When the effective chlorine content is 24.52 mg/L, the sterilization efficiency for E. coli is 95.81%. Nie Xiaofeng et al. soaked eggplant fruit with acidic electrolytic water with pH 5.9, the soluble solid content was higher, the weight loss rate and Browning index were smaller, which had positive effects on the external and internal quality of eggplant fruit. Pinto et al. studied the bactericidal effect of several different bactericidal solutions on fresh cut chicory after 5 min treatment, and the neutral electrolytic water had the best effect.
