At present, pesticides that are still widely used in domestic agricultural production not only pollute the environment, but also cause harmful residues in agricultural products and soil. Repeated use can reduce soil quality and disrupt ecological balance.

1) Adjust the acidity and alkalinity of the soil, and improve the soil.

The use of quicklime and sulfur powder to regulate soil acidity and alkalinity, although effective, can also cause secondary pollution to the environment. In addition, the cost of renovation is high, and long-term use can also cause soil degradation. The method of using acidic water to regulate alkaline soil is better. In addition to effectively correcting soil pH environment, the most important thing is that there will be no residue and the cost is extremely low It is also extremely convenient to use, and using acidic water can kill some soil borne bacteria, creating a micro current environment for the soil and greatly reducing the number of bacteria.

2) Promote seed germination and seedling growth.

Used for soaking plant seeds, it can increase germination rate. The germination rate of soaked plant seeds increased by 60%, and the young plants were robust, healthy, and had a high survival rate. Therefore, for the production of sprouts and box leafy vegetables, it can significantly increase yield and improve quality.

3) Replace chemical pesticides for sterilization and pest control of crops.

Due to its rapid lethal effect on various plant diseases and pests, strong acid water is very suitable as a substitute for chemical pesticides. Moreover, it is highly efficient and instantaneous in sterilization, safe to use, and has no chemical residue. It has a wide range of applications and does not only work on specific objects like chemical disinfectants. Experimental results have shown that it can kill acid bacteria, fungi in 1-3 minutes, and Bacillus in 3-5 minutes. Used for crop cultivation, it can achieve the effect of reducing or even eliminating pesticides to a certain extent. It should be noted that water electrolysis must come into contact with bacteria to kill them, and most plant diseases have already penetrated deep into tissues once they occur. Spraying water electrolysis cannot kill pathogens inside tissues. Therefore, prevention should be the main focus of spraying water electrolysis. However, the experimental results also showed that spraying water electrolysis can increase the activity of plants themselves, enhance their resistance to pests and diseases, and reduce the occurrence of pests and diseases. It has a insecticidal effect on aphids. Although acidic water has strong acidity, it does not cause any harm to crops. In addition to spraying once every 7-10 days, it is also necessary to pay attention to the principle of alternating the use of acid water and alkali water for varieties that are sensitive to strong acids. Generally, after spraying acid water, spray alkali water 30-60 minutes later to avoid acid hazards.

4) Strong alkaline water can enhance photosynthesis, promote crop germination and growth, fruit coloring, and increase sugar content.

5) Anti mold and fresh-keeping treatment of agricultural and sideline products.

Using water electrolysis treatment to remove the skin of fruits and vegetables and some pesticides and fertilizers that have entered the interior of fruits and vegetables, killing bacteria, fungi, and pathogens that are difficult to treat on the surface of fruits and vegetables, extending the preservation time, and ensuring the green and safe appearance of fruits and vegetables.

Taking refrigerated strawberries as an example: Soak strawberries in strong acidic water and strong acidic water plus calcium chloride treatment solution for 10 minutes before refrigeration (with no treatment as a control), and then refrigerate at 0 ℃ for 12 days. The results showed that soaking strawberries in strong acidic water and strong acidic water with calcium chloride treatment solution can significantly inhibit the respiration of strawberries, suppress the activity of polygalacturonase and carboxymethyl cellulase, effectively maintain the hardness of the fruit, and greatly reduce decay. The good fruit rate of the strong acidic water treatment group after 12 days was 100%, while the good fruit rate of the control group (untreated) was only 85%. This indicates that washing fruits and vegetables with strong acidic water not only has good washing, sterilization and disinfection effects, but also can extend the shelf life.
