It is not suitable to use metal containers for raising flowers.
Do you know about these? Regarding the common knowledge of raising flowers, it is not suitable to use metal containers. Next, the editor will introduce to the netizens.
Cut flower preservatives make the solution acidic (with a pH of about 4 to 5). Acidic solutions can displace metal ions on metal vases, leading to high concentrations of metal ions dissolved in the solution, showing plant toxins, resulting in severe leaf scorch and petal wilt in fresh flowers.
Elements harmful to cut flowers (plant toxins)
Many metals can be made into vases or baskets. However, many elements can cause damage to fresh flowers even at low concentrations, such as chlorine, boron, zinc, cadmium, copper, and iron. High zinc solution: If acidic solutions are placed in zinc buckets, the concentration of zinc ions in the solution will increase to 160 mg/L, which can cause severe leaf and petal damage. Even if tap water is used in zinc buckets, the displaced zinc ions can be very harmful to flowers.
High copper solution: When the concentration of copper ions in the solution reaches 10 mg/L, it can cause significant damage to cut flowers.
High fluoride solution: The concentration that harms cut flowers is 5 mg/L. Fluoride is easily harmful to chrysanthemums and cynobium, and it is also very harmful to the petals of African daisies. The symptoms are blackening of the petals of African daisies and not just in red varieties. Experiments by Baokang Keli Fresh Company have shown that when the fluoride concentration is 2 mg/L, lilies will turn yellow faster.
How to avoid damage to fresh flowers from zinc buckets
If it is necessary to use zinc buckets, how can we minimize the damage they cause to fresh flowers?
The answer is very simple: put a plastic liner in the zinc bucket to prevent the zinc surface from coming into contact with the solution.
The above introduction about the unsuitability of using metal containers for raising flowers, I hope everyone will like it!
