Application of potassium permanganate

Potassium permanganate, also known as "gray manganese oxide, manganese strong ash", also known as PP powder, in medicine as a disinfection preservative, external disinfectant application, for bacterial infection and fungal infection of superficial diseases have a certain effect, but also a strong curing agent, but also can remove odor and so on.

Because the speed of oxygen released by potassium permanganate is slow, the soaking time must reach 5 minutes to kill bacteria, cold boiled water should be used when preparing aqueous solution, hot water will make it decompose and lose release, and the preparation of aqueous solution can only be preserved for about two hours. when the solution turns brown-purple, it loses its disinfection effect, so it's best to go with it and not be used for a long time.

For fungal diseases, not only can not control mold reproduction will sometimes aggravate the disease, generally should take broad-spectrum antibiotics and other drugs.

At present, during the peak period of direct orchid disease, the majority of orchid friends should be careful to use potassium permanganate and prescribe the right medicine, otherwise your orchid will flow eastward and never return.

As for the application of potassium permanganate in orchids, in principle, I only use it under the following circumstances:

1. The newly purchased seedlings, with rotten roots, empty roots, injured roots, broken roots and broken pseudo-corms, are soaked in 1500 times solution for five minutes, dried and sterilized, and the key lies in wound healing.

2. The orchid basin matrix fertilizer is too abundant. Due to the long-term use of the orchid basin and the increase of nutrients such as nitrogen, phosphorus and potassium, the orchid is eutrophicated. The orchid was watered with 1500 times potassium permanganate solution for about 8-12 hours and then watered thoroughly.

3. Due to the peculiar smell of the plant material in the orchid basin for a long time, combined with the anticorrosion in April, the above method is also used once.

4. The smell of self-made fat and water is too heavy, add an appropriate amount of potassium permanganate.

The above is for Lanyou's reference.
