Why water the green trees in rainy days?

I think many people don't understand why we should water the green trees in rainy days. Some people even think that this is a waste of resources, but in fact, there is a certain scientific basis for watering green trees in rainy days, mainly for the following three reasons: < P > First, to avoid flowers and plants from dying due to lack of oxygen. When there is a great controversy about watering green trees in rainy days, some landscape experts have specially done science popularization, because the oxygen content in rain is very low, and after continuous heavy rain, the oxygen content in soil will be greatly reduced. In order to prevent flowers and plants from dying because of lack of oxygen, watering the green trees in rainy days is to increase the oxygen content.

We often see that some plants suddenly die after rainy days, and many people think that they are soaked to death by too much rain. But in fact, only a few plants will be drowned because of too much water, but most plants can't survive because of lack of oxygen.

the second is to avoid the breeding of miscellaneous bacteria, which will lead to plant diseases. In rainy days, some green belts will be flooded by rainwater runoff, and the leaves and plants will be stained with dirt. Under such circumstances, it is easy for the job to breed miscellaneous bacteria, which will cause plants to get sick. In fact, some flowers and plants or vegetables planted at home in rainy days also need to be washed with water, in order to avoid plants getting sick as much as possible. And sometimes the precipitation in rainy days is not enough to nourish plants, and it is still necessary to water plants to alleviate the water shortage problem.

thirdly, washing the ground and watering the green trees in one go in rainy days, which is convenient for operation. Regular cleaning will know that in rainy days, the ground is easier to be washed clean, because the slag on the ground has been softened by rain, which is much more convenient to clean than usual. Sprinklers usually have to clean the ground and water the trees in the green belt at the same time, so they often do these two things together, which can save a lot of time and labor costs.

It is precisely because of these reasons that we often see that sanitation workers are still working hard in rainy days. They water the trees at this time, on the one hand to facilitate their work, and on the other hand to protect the health of vegetation. Although trees in green belts are usually very easy to survive, in their daily production, the environment they face is far worse than we thought, such as a lot of dust and car exhaust.

Therefore, in the process of preserving them, more scientific basis is needed. Many people don't understand why they water the trees when it's already raining, and question others with narrow ideas. But the reason why sanitation workers do this for a long time must have his reasons, and the prolocutors grow very well after watering in rainy days, which shows that this method is feasible.
