The Application of Potassium Permanganate in Flower Cultivation
This article provides answers to common questions about flower cultivation, focusing on the application of potassium permanganate. Let's take a look together.
Potassium permanganate is a strong oxidant widely used due to its minimal residue and low likelihood of causing harm to plants. It has also become a common tool in home gardening. Novice gardeners, seeing others use it, may want to use it as well, but they may not be familiar with it. So what exactly can potassium permanganate do in home gardening?
1. For imported bulbous plants like hyacinths and narcissus, which often carry mold after being shipped across the sea, many gardeners use potassium permanganate solution to disinfect the bulbs.
2. It is common practice to use potassium permanganate solution to disinfect cuttings and tools during the propagation of flower seedlings. This indeed helps prevent decay and promotes root growth.
3. Some gardeners like to disinfect seeds with potassium permanganate solution before sowing, especially for plants like cacti and various succulents. However, a recent article has questioned this method of sterilization. The author believes that potassium permanganate can reduce the germination rate of seeds, so gardeners should consider this when using it.
4. To prevent plant diseases, soaking seeds or seedlings in a 0.1% potassium permanganate solution before sowing or transplanting can prevent diseases like soft rot, downy mildew, and rhizome diseases.
Precautions when using potassium permanganate:
First, avoid using stagnant water (mineral water), polluted water, or hot water to prepare the solution. Second, the solution should be prepared and used immediately to prevent oxidation and失效. Third, prevent mixing with strongly alkaline pesticides to avoid degradation and失效.
The above introduction to the specific applications of potassium permanganate in flower cultivation is shared in the hope that everyone will find it useful!
