Strong oxidizing acidic water and strong reducing alkaline water,according to the electrolysis principle,is electrolyzed by the special generator.The physical and chemical property of that can disinfect and prevent plant disease and insect pests,which has extensive using space .Here produces the disinfect mechanism and productive operation

1.Productive principle of electrolyzed water generator

Water is electrolyzed by electrode to compose OH-and H+,which can react with CL- and K+in the KCL solution to generate HCLO and KOH in the function of anion exchange membrane whose function make sub chloranion convergent to the positive pole,and make OH-convergent to the negative pole.Here are the strong oxidizing acidic water and strong reducing alkaline water in two electrolyzed cell.

2.Disinfect and operative mechanism

Water and 0.1% KCL form the electrolyte solution with high conductivity,and form sodium hypochlorite with ORP (+900-+1200mv),PH value 3-2.7,and which form the KOH solution with ORP(-800mv),PH 10-13.

Acidic water is used by disinfecting in the agriculture.The disinfect principle is on the chemical and physical property,the physical property is of the high ORP which touches with virus and microbe,and impulsively acquires electron from the biological membrane to change the normal ORP and penetration of cell in order to destroy the oxidation of membrane permeability alike drilling on the cell membrane leading to leak contents out.The physical process can reach the best effect in 1-10 minutes which is more rapid and utmost than the chemical’s without any drug resistance.The chemical property is that rebuilt the strong acidic surrounding not adjusted with microbe to refraing from the microbe growth(microbe in 3 PH value,but acidic water under PH value 2.7),and is that the CL- in HCLO also is the disinfectant to refrain from it.Because of the synthetic disinfect effect,it is better than other agriculture disinfectant.The alkaline water also has the broad purpose which has not only the function of neutralizing acid and alkali balance but also has the function of promoting crops grow and colorize due to the KOH which is fully utilized in agriculture production.

3.The application of improving soil in orchard

The acid-alkali balance in soil is relative with the fruit growth,more or less balanced of soil cause the barrier of root to absorb nutrition alike shortage of alkaline in ferrum,shortage of acid in potassium,zinc,magnesium and so on. Especially in southern,orange tree’s growth is hard in red and yellow strong acidic soil under PH value 4.5 to be regulated by lime.Most trees is also hard in drought zone and saline alkali land in PH value over 8 to be regulated by sulfur powder,which destroy the absorbing balance of mineral nutrition and cause the second pollution,reaching to the best PH range 5.5-6.5.The acidic water and alkaline water can regulate the orchard with unbalanced soil in low cost without any residue according to Japan experience,the application of acidic water can kill microbe, and create the micro circuit surrounding to lower the microbe cardinal number in the diluting way.

4.The application of preventing from pest and microbe

The disinfect effect of electrolyzed water is respected by producer in Japan,where non pollution pesticide orchard combines electrolyzed water with biological killing pest technology to safely produce in order to resolve the pesticide residue for health and ecology.closing orchard by electrolyzed water can reduce the microbe cardinal number.It is the best control efficiency through electrolyzed water alike peach scab,scab,contracted leaf disease,perforation disease, ulcer,black spot,rust and wheel disease.Especially the electrolyzed water used for grape is better efficacy than pesticide’s.But in the usage,must notice the exchange rule for acidic and alkaline water for sensitive species to spray in 7-10 days.It avoids from destroying that some young tree after spraying acidic water need to be spray alkaline water after 30-60 minutes.The application of that in Japan has no harm performance for human’s skin and smell,orchard worker in Lishan county, Japan take electrolyzed water as the main measure to disease prevention to realize the zero pesticide planting.

5.The application for the enhancing fruit quality

Acidic water has the excellent disinfect effect,and alkaline water is the best fertilizer,which has the KOH water with high ORP to promote the growth and improve the appearance of fruit even and enhance the sugar degree and colorized degree.

6.The application of freshness and reservation

The freshness and reservation of fruits is important procedure in the productive process.In China,the cause of keeping fresh technology is behind to lead reduction of output,but it difficult to execute because the large-scale reserve needs the big investment,only to disinfect by chemical in room temperature to lead bad effect and chemical residue.Electrolyzed water can process the leave tree treatment and convergent treatment to enhance the working efficiency and keeping fresh effect.Chemical disinfect treatment can impact the appearance and chemical residue before reserving for big-scale keep fresh company.Electrolyzed water is the ideal keep fresh measure that it can quickly kill all kinds of bacteria and rapidly reduce water without any pollution and residue. As strawberry shows the disinfect and keeping fresh effect. Before reserving,strawberry separately is soaked into strong acidic water and acidic water with CACL about 10 minutes and is reserved under 10 degree about 12 days. The result show that the strawberry soaked in to the acidic water and CACL could remarkable refrain from breath and activation of polysaccharide of poly and carboxymenthyl cellulose to order to keep it hardness avoiding from corrode. The perfect fruit rate is 100% in the acidic water.But the contrast only85%.The cleaning treatment of electrolyzed water for strawberry has the good washing ,disinfecting and keep-fresh functions.

7.The application of non-pollution fruits

It is possible that produce non-pesticide fruits in Japan.Orchard worker use electrolyzed water to disinfect pests and combine with traditional medicine preparation to reach the best effect of non-pollute fruit without any residue named HANFANG medicine in Japan.It is focused on the non polluted fruits,which is the vegetable original biological medicine prepared with Chinese herbal medicine prepared with a proportion of phellodendron,tangerine peel,liquorice,mint,pepper,coptis and so on.Its scent can kill spider and pest to reach the killing effect.

8.Employment and notes:

The usage of electrolyzed water is sample that acidic water and alkaline water are sprayed in sunny and less moisture day,which can impact the effect and bar the electrolyzed water to evaporate and reduce and has slightly hurt some sensitive species.Moreover,electrolyzed water had be better reserve the closet plastic tub.If convenient,had better fertilizer and prevent,because its ORP is high if produce.in open location,the ORP lower without any obvious variation for the acid and alkaline balance,but the effect is good.it is noticed that the pesticide combining with electrolyzed water will be impacted the effect:acidic pesticide not with alkaline water and alkaline pesticide not with acidic water. Acidic pesticide dissolved by acidic water will raise the dissolution and dispersion degree,and raise the penetration of pesticide on the leave.The application of electrolyzed water in the fruits tree has along time in Japan where they has electrolyzed water rule in agriculture to develop on the standard.We can draw lesson from them and combine with our productive condition to develop its technology and operation for our non-pollution production and maximum function of sustainable development.It is of physical disinfect course in agriculture without any environmental pollution and residue.It is significant to lower the productive cost.
