Hydrogen peroxide is what we usually call hydrogen peroxide. It is generally used as a household disinfectant or bleach. It is a colorless liquid. In high concentrations, it is flammable or corrosive. The hydrogen peroxide diluted with water can produce oxygen and remove germs. It can also be used appropriately when growing flowers.
Hydrogen peroxide can be decomposed into oxygen and water. It is very environmentally friendly to use when growing flowers, but you must use the appropriate concentration and pay attention to proper watering. This is a technique for organic gardening.
1. Disinfect garden tools
Because hydrogen peroxide has very good antibacterial activity, it is widely used in medical institutions. Hydrogen peroxide can also be used to disinfect flowers when growing flowers. In fact, when we disinfect flower pots, soil and various gardening tools, we can properly Use hydrogen peroxide, but use an appropriate ratio. Generally, use a concentration of 6%-9% for disinfection. Before use, garden tools can be soaked in hydrogen peroxide diluted with water, which can reduce Infestation of pests and diseases.
Hydrogen peroxide can eliminate most bacteria, viruses and fungi. If the concentration exceeds 10%, it will easily damage plants. Hydrogen peroxide of this concentration cannot be sprayed on plants.
2. Use when sowing
After the warmth of spring, many people will buy some seeds for sowing and cultivating plants. To increase the germination rate of seeds, it is very important to ensure that some sterilized soil and flower pots are used. At this time, hydrogen peroxide can be used for disinfection.
We usually use river sand, perlite and vermiculite for sowing. Appropriately add some mulch or peat soil. When disinfecting flower pots and soil, we can use hydrogen peroxide appropriately. This is to avoid soil Carry germs or eggs.
Use 3%~6% hydrogen peroxide solution for the soil. This concentration of hydrogen peroxide solution can completely remove the eggs from the soil. After a few hours, the hydrogen peroxide will completely decompose, generally after 8 Use the disinfected soil after ~12 hours.
3. Seed disinfection
When we sow, the germination rate of seeds is relatively low, or the seedlings hang up after they grow out. In addition to the fact that the soil is not disinfected, there may also be some pathogens carried by the seeds. The seedlings are killed before and after germination. Sometimes the seedlings are not easy It grows out, but it falls down, usually because it has not been sterilized.
You can add 3% hydrogen peroxide solution to warm water for a while, then soak the seeds in it for 5 minutes, then pick it up and soak in clean water for one minute, drain the water, and then use it for sowing seedlings.
4. Speed up germination
Seeds that have been soaked in hydrogen peroxide will germinate faster and grow healthier. These seedlings are not prone to lodging because oxygen will be released when hydrogen peroxide is decomposed. When seeds germinate, their oxygen content requirements are It is relatively high, so proper soaking of seeds with hydrogen peroxide solution can increase their chances of germination.
In addition to directly soaking the seedlings with a concentration of 3% hydrogen peroxide solution, after the seedlings grow out, you can properly water them with 1% hydrogen peroxide solution, which can be watered once a week. This can also promote the root growth of plants .
5. Other functions
Hydrogen peroxide can also be used to combat various common fungal diseases. If plants are infected with powdery mildew, rust or other fungal diseases, especially potted plants, you can use hydrogen peroxide. Of course, pay attention to the concentration when using hydrogen peroxide.
Generally, use a spoonful of 3% hydrogen peroxide solution mixed with 200 ml of water, then put it in a watering can and spray it directly on the potted plants.
Some old gardeners think that it is safer to spray hydrogen peroxide with a concentration of 6% to 9% on plants, but in order to avoid burning plants, it is best to use hydrogen peroxide with a concentration of 3%, which must be mixed with water before use. , The ratio of 3% hydrogen peroxide to water is 8:1.
Spraying such a solution on plants can also prevent bacterial infections and protect plants well. After pruning the plants, you can properly spray hydrogen peroxide solution to prevent infection of various diseases and insect pests. Hydrogen peroxide solution is also a good insect repellent, which can prevent various pests from approaching.
If you want to use hydrogen peroxide to remove weeds, then use a concentration of 10%. This concentration is also harmful to plants. If you want to remove some weeds beside the stone road, you can use 10%. Hydrogen peroxide above %, spraying on weeds can directly burn the leaves and roots of plants, and hydrogen peroxide will quickly decompose in the sun, spraying in the morning and evening is best.
It should be noted here that hydrogen peroxide solution with a concentration of more than 10% will cause damage to plants, and it is also corrosive. After spraying, wash your hands with clean water.
