84Can the disinfectant disinfect the flower soil?
1. The 84 disinfectant cannot be used to disinfect the flower soil. If you do, it will have a bad effect on the flowers, or even dead seedlings.
2. Use 84 disinfectant to disinfect the flower soil. The 84 disinfectant gradually generates hypochlorous acid in the soil, and hypochlorous acid is also unstable. It may release chlorine gas and cause damage to the root system of flowers. It has adverse effects, and even affects the activity of the root system and causes the death of flowers. The irritating odor and corrosiveness of 84 disinfectant also have a fatal effect on the root system of flowers.
3. 84 disinfectant has strong irritating, corrosive and oxidizing properties, and the usage amount should not be too large. 84 Disinfectant has strong irritating, corrosive and oxidizing properties due to its own nature, so it has a strong disinfection and sterilization effect, which can kill harmful bacteria in flower cultivation soil, and play a role in disinfection, sterilization and disease prevention. effect.
4. 84 disinfectant is different from the fungicides for plants, and has a strong destructive effect on flowers. In the disinfection and sterilization of flower cultivation soil, the concentration is difficult to control, the disinfection and sterilization effect is poor if too low, and the residual amount of the cultivation soil is too high, which will affect the growth and development of flowers.
5.84 disinfectant is an acidic substance, and the amount of the disinfectant will cause acidification of the cultivation soil. Long-term use of 84 disinfectant, although the flowers are still alive, the acidification of the cultivation soil is getting higher and higher, which will inevitably affect the normal growth and development of flowers. Therefore, 84 disinfectant cannot be used many times on the flower cultivation soil, and must affect the normal growth of flowers or the existence of life.
The best way to disinfect and kill flowers and soil
