The main ingredient of injecting contraceptives into the trees in the park is gibberellin, which can inhibit the orchard formation of female poplars and willows and avoid the formation of flying flocks. After the drug is applied to trees, it can inhibit the generation of birds and beautify the urban environment. But this drug is harmless to human body, and it will take 3~5 years to see obvious effect. Birth control pills for trees will not directly volatilize into the air, so they will not pollute the environment and are harmless to human body. People don't have to worry too much about this.
Most of the trees injected with contraceptive needles in the park are aging trees, because these trees produce more flying flocs, which can be effectively reduced by control, and after using drugs on these trees, it is not found that they affect the normal germination and growth of trees. Most of this drug is absorbed by trees after injection, which will be decomposed by new metabolism of trees, and rarely volatilized into the air, which will not affect the environment and cause no harm to human body.
After the trees in the park are injected with contraceptive injections, the number of catkins is obviously reduced, and the environment will be healthier, which is more conducive to the normal life of human beings. It is harmless to human body and can provide people with a better living environment. This is a scientific method to control fly ash from trees and an effective means to beautify the environment. It will only effectively improve the urban environment, make the streets cleaner and the air fresher, and will not cause harm to human health.
Poplar and willow trees grown in nature are the main trees that produce flying flocs. These trees are divided into female trees and male trees. Female trees can only bear fruit after getting pollen from male trees, which contains a lot of white catkins. In order to reduce the output of these catkins and poplars, professionals will control the trees with drugs, and by injecting corresponding drugs to inhibit female pollination, the production of white catkins can be prevented from the roots. This is a scientific and effective prevention and control method, which is good for human body and environment.
