What are the benefits of potassium permanganate for crops in agriculture

Disinfection, sterilization, insecticide, and so on, which is the same in agriculture and aquaculture, but now agriculture generally has organic pesticides.

Potassium permanganate has strong oxidation, so it can be used to sterilize, and if you have athlete's foot, you can put half a mung bean to wash your feet! Can't put too much....Will burn**!

It is oxidized and decomposed in ethanol and hydrogen peroxide.

Potassium permanganate contains two nutrients, manganese and potassium, which are essential for plants, which can promote plant growth and can be described as a dual use of medicine and fertilizer. In addition, its cost is low, easy to purchase, and it is safe for humans and animals when used, non-toxic, no residue to crops, no pesticide damage, no pollution to the environment, and has a peculiar effect in the production of pollution-free vegetables and flowers. Specifically, it includes the following points:

1.Prevention and control of cataplexy and blight.

2.Control of downy mildew.

3.Prevention and control of soft rot.

4.Prevention and treatment of viral diseases.

5.Shed sterilization and disinfection.

6.Disinfection of sowing soil.

When preparing potassium permanganate solution, well water, river water, tap water, etc. can be used, but avoid using stagnant water, sewage, hot water, etc., otherwise it will reduce its sterilization effect, because potassium permanganate and organic matter reduction reaction, manganese dioxide will be generated, and lose its bactericidal effect. Therefore, it can only be used externally, and can only be used with matching.

The role of potassium permanganate in agriculture is as follows:

Potassium permanganate is a strong redox agent, and its solution has strong sterilization, disinfection and antiseptic effects, and it is used to prevent and control vegetable diseases, and has achieved ideal control effects; Potassium permanganate contains two nutrients, manganese and potassium, which are needed by plants to promote plant growth. In addition, its cost is low, easy to buy, safe for people and animals when used, non-toxic, no residue on crops, no drug harm, no pollution to the environment, and has a peculiar effect in the production of pollution-free vegetables and flowers.

Agricultural potassium permanganate has sterilization, disinfection and antiseptic effects.

The use of potassium permanganate to control plant downy mildew has a good effect, which is significantly better than pesticides such as chlorothalonil and zeb. For example, melon leaf chrysanthemum is sprayed with potassium permanganate 800 600 times before flowering after 2 leaves and 1 heart after emergence, 1 time in 5 7 days, and 4 times in a row, which can effectively prevent the occurrence of downy mildew. If there is a central diseased plant, spray it 3 times with 600 times of potassium permanganate, with an interval of 5 days, which has a good control effect on downy mildew.

In the production of chemicals, it is widely used as an oxidizing agent, such as an oxidant for saccharin, vitamin C, isoniazid and benzoic acid; used as preservative, disinfectant, deodorant and antidote in medicine; In water purification and wastewater treatment, it is used as a water treatment agent to oxidize hydrogen sulfide, phenol, iron, manganese and organic, inorganic and other pollutants to control odor and decolorization.

1. Fertilization at the young age in spring.

In the process of planting fruit trees, spring is an important period for their budding, leaf development, and flowering. This period includes the energy of all life activities of the fruit tree and the growth of all parts, and it is very necessary to provide a large amount of nutrients, which is related to whether the fruit tree can grow and develop healthily in the later stage. So in the spring, it is the first important period for the fruit trees to be fertilized.

2. Fertilization at the beginning of the fruit period in summer.

Summer is an important period to promote the differentiation of fruit trees and improve the yield and appearance quality of fruit trees, so it is also very necessary to top dressing in summer. According to a large number of practices, it has been proved that when topdressing in summer, the fertilizer time with high potassium, low nitrogen and low phosphorus is the most appropriate. And the earlier the topdressing time, the better, which is most beneficial to the growth of fruit trees.

3. Fertilization in autumn during the full fruit period.

Autumn is an important period for fruit trees to store nutrients, and fertilization has a very important transitional effect on fruit trees at this time. Because if the fruit tree bears too much fruit or has too many insect pests during the growing season, it may cause overnutrition; If the nutrients stored in the tree are not enough to continue budding, flowering and leafing in the following year, the overall yield and quality of the fruit tree will be affected. Therefore, during the period from fruit picking to before defoliation, urea and bika silicon-soluble potassium dihydrogen phosphate are the most suitable.

Spray the whole tree once in about 10 days, and repeat the operation 3 to 4 times; This can help the fruit tree store nutrients and promote flowering and fruiting in the coming year.

Fourth, fertilization precautions.

In the fertilization process, the differences in the characteristics of fruit trees also determine the subtle differences in fertilization methods. Fruit trees with dense roots should be applied deeply, about 40 to 60 cm deep; Fruit trees with sparse roots need to be applied shallowly, at a depth of 30 to 40 cm. When fertilizing, the fertilization area should be dominated by the projected edge of the canopy and a little farther away, so as to maximize the effect of the fertilizer.

In general, when fertilizing fruit trees, only fertilization at the right time can improve fertilizer utilization efficiency and increase fruit tree yield.

1. In the production of chemicals, it is widely used as an oxidant, such as an oxidant for saccharin, vitamin C, isoniazid and benzoic acid.

2. It is used as a preservative, disinfectant, deodorant and antidote in medicine.

3. In water purification and wastewater treatment, it is used as a water treatment agent to oxidize hydrogen sulfide, iron, manganese and organic, inorganic and other pollutants to control odor and decolorization. It is also used as bleach, adsorbent, colorant and disinfectant.

4. In mining metallurgy, it is used to separate molybdenum from copper, remove impurities from zinc and cadmium, and oxidants for compound flotation; It is also used as a bleaching agent for special fabrics, waxes, greases and resins, an adsorbent for gas masks, and a colorant for wood and copper.

Potassium permanganate has a great effect on plant growth, and it can well control a variety of diseases, such as blight, blight, root rot, etc. It can also disinfect the roots and seeds of plants, and the sterilization and disinfection effect is very good, so that the plants can grow better and the seeds will germinate faster.
