Planting flowers can adjust people's spiritual life, make people relaxed and happy, eliminate fatigue, improve physical and mental health, exercise their will and improve their scientific and cultural literacy. Planting flowers in leisure time is also a kind of enjoyment.
A city can't live without trees and flowers, or without trees and flowers, it will lack the realm of birds and flowers, and the changes of spring, summer, autumn and winter will also lack business.
The role of flower cultivation
Planting flowers can purify the air, such as cypress, oleander, anchovy, etc., which is not only beautiful, but also can take medicine to reduce dust, reduce noise, prevent pollution, adjust climate and maintain ecological balance. For example, gladiolus is used to monitor fluoride. When there are one billion kinds of harmful gases in the air, the leaves of this plant will dry up, and geranium and oleander can absorb sulfur dioxide.
Many flowers and trees can even secrete fungicides, which can kill diphtheria, tuberculosis, typhoid fever and dysentery.
