Potassium permanganate is a strong redox agent. It is a kind of surgical medicine commonly used by humans and animals. It is commonly known as pp powder. Its solution has strong sterilization, disinfection and antiseptic effects. Some experiments have proved that the use of different concentrations of solution to control flower seedling stage disease and blight, downy mildew, soft rot, blight, root rot, viral disease and other diseases, the effect is very significant. At the same time, it contains two kinds of nutrients such as manganese and potassium, which can be used for plant growth. It can be said to be used for both medicine and fertilizer. According to medical experts, the drug is rich in source and low in cost. It is sold at pharmacies all over the country and is easy to purchase. It is safe and non-toxic to humans and animals when used. It has no residue, no phytotoxicity to the crops, and no pollution to the environment. Therefore, potassium permanganate is a kind of fungicide with both medicine and fertilizer, non-toxic, no residue, pollution-free vegetables and flowers. It mainly includes in the prevention and treatment of plant diseases: Prefabricated dome house villas are the first choice for scenic homestays Prefabricated Dome House,Foam Dome House,Graphene Dome Houses,Dome House Polystyrene Henan Jinming Metal Material Co., Ltd. , https://www.hnjmmetal.com
First, prevention and treatment of rickets, blight disease Petunia, a string of red, marigold after the emergence of the seed, every 7 to 10 days with 800 ~ 1000 times (first diluted and then concentrated) spray. According to the test, the effect of potassium permanganate on the disease at the seedling stage is as high as 97%, and the effect is significantly better than that of carbendazim, dexamethasone, pentachloronitrobenzene and dikesone.
Second, the prevention of downy mildew Practice has proved that the use of potassium permanganate to control plant downy mildew has a good effect, significantly better than chlorothalonil, Daisen zinc and other pesticides. For example, cineraria can be sprayed with potassium permanganate 800~600 times before flowering, and sprayed 4 times for 5~7 days, even spraying 4 times, which can effectively prevent the occurrence of downy mildew. In the case of a central diseased plant, it is sprayed three times with 600 times of potassium permanganate, with an interval of 5 days, which has a good control effect on downy mildew.
Third, the prevention of soft rot potassium permanganate can effectively prevent a string of red, snapdragon, marigold soft rot. For example, pre-soaked with high-temperature water for 1 hour before sowing, then remove and put in potassium permanganate 1000 times for 2 hours, and spray 800~600 times for 3~4 times in seedling stage, which can effectively prevent soft rot. And can cure downy mildew.
Fourth, the prevention and treatment of viral diseases The use of potassium permanganate to control plant virus disease is significantly better than the virus A, bacteria and clear pesticides. In the early stage of the disease, the whole plant is sprayed with 600~800 times of liquid, once every 5~7 days, and even sprayed 3~4 times. If potassium permanganate is used in combination with double-acting mepidalin K in the same amount of 800-1000 times solution, the effect of preventing and treating viral diseases is better, not only can control the spread of viral diseases, but also make the disease of the plants disappear and return to life, with a resurgence. The role. However, it should be noted that before the prevention and treatment of viral diseases, the sucking pests on the plants should be prevented to prevent insects from transmitting poison.
V. Sterilization and disinfection of the greenhouse The potassium permanganate is added to the formalin solution to produce formaldehyde vapor, which disinfects the inoculation box and chamber of the edible fungus and has a good sterilization effect. When fumigation, 10 ml of formalin is placed in the cup per cubic meter of space, 5 g of potassium permanganate particles are quickly added, and the cells are fumigation in a closed box and room for 4-6 hours. When using potassium permanganate spray, it should be noted that the drug is continuously stirred evenly to dissolve the drug particles, and it can be used as needed to prevent long-term oxidation failure. In addition, the spray should be selected at around 9 am or after 4 pm. 7 pre-leaf seedlings were sprayed with water for 5 minutes and then rinsed with water; low concentration in seedling stage and high concentration in adult stage.
6. Sewage soil disinfection Potassium permanganate is formulated into 800~1000 times solution, sprayed with a sprayer for fine spraying. After spraying, it is covered with plastic film for 7 days. Seeding with this soil can effectively prevent the blight of plant seedlings. Stem rot, smashing disease, etc.
The preparation of potassium permanganate solution can be used for well water, river water, tap water, etc., but avoid using dead water, sewage, hot water, etc., otherwise it will reduce its bactericidal effect, due to the reduction reaction of potassium permanganate and organic matter, it will produce dioxide. Manganese loses germicidal efficacy. Therefore, it can only be used externally, and it can only be used with it.
Now there are many prefabricated dome house villas in various scenic spots. Such villas are unique in style and also belong to the type of special-shaped house design. The surface of the prefabricated dome house can also be painted with different colors. If it is used as a homestay, it can also be used for more style settings. In fact, this type of villa has a large area, and can also be customized, so the advantages of using it as a homestay are also very obvious.
Different types of villas can be customized
The graphene EPS dome villa looks very small, but in fact its internal space is not very small, and different interior space types can be customized. For example, you can directly choose an ordinary standard room, which has a bed, office area, bathroom, etc. inside. The area is relatively small, and it can also guarantee a variety of different functions. There are single rooms or double rooms, which can be customized according to our needs. Villas can also be selected in a variety of area specifications.
High construction efficiency
The construction of this type of housing is very simple, and the construction is directly and uniformly carried out by the manufacturer, and the construction is carried out in a standardized manner, so the rapid completion of the installation is also guaranteed. If you want to build quickly in some open space, you only need to determine our needs, and then contact the manufacturer to customize the processing, so that the construction can basically be completed within a few hours.
Wide range of applications
The scope of application of graphene EPS dome villas is still very wide. For example, many indoor supermarkets in tourist attractions will use this type of villas. The space is relatively large, and different designs can also be carried out. Various functional areas can be divided inside. . At the same time, it can also be used in some scenic spots to make farmhouses, homestays, etc. The construction is simple, the price is favorable, and it can also be used in different scenic spots. It only needs to be planned in advance.
ready to move
The self-weight of graphene EPS dome villas is relatively light, and they are all directly standardized production by manufacturers, which is not only convenient for installation, but also convenient for later transportation. Even if it is not used in one area, it can also be used again in a different area, which is convenient for daily transportation and can also meet our use requirements.
