The negative effects of a variety of plants in the city, the plants that can be grown in the city g

The negative effects of too many plants in urban areas are probably these: the number of branches and foliage is too lush or not pruned in time, which will partially block the driver's vision, traffic road signs, etc.; Trees that are too tall may touch power lines. That's all I can think of.

As for transpiration and moisturizing, there shouldn't be much of a negative effect. The water lost by transpiration is mainly absorbed from the underground roots, and does not have a negative impact on the humidity of the surface and air, on the contrary, the water vapor emitted by transpiration can also increase the humidity of the surface and air, and the moisturizing ability is self-evident.

The urban area mentioned here is mainly only on the side of the road, near the road near the motor vehicle, and the others should not be included in the scope of affecting traffic.

The leaves are also green when it does not rain or get wet: this is because the plants draw water from the soil underground, and the roots of the plants reach deep into the soil. The leaves of plants are green because there is chlorophyll in the leaves, so the leaves remain green.

This will not be dried, groundwater is widely distributed, and it is continuously transported to the surrounding places with less moisture through capillary action, and there are many ways of water circulation such as rainfall and night dew to ensure the best moisture. Of course, if the drought continues, it will also cause the plants to die due to severe water shortage, which is the so-called "drought death".

Water can also flow to the ground when it rains, and in the same way, water will penetrate into dry places, just like towels, put dry towels and wet towels together, dry towels will also get wet, and the same principle is true on the land. Part of the water penetrates into the ground in this way, and part of it flows into some underground pits during the flow process, and eventually it also circulates underground, and then repeats the above process: underground - infiltration - above ground - plant absorption - transpiration - dispersal into the air - rain - underground.

As mentioned on the 3rd floor, trees need to absorb groundwater to keep it green, but will it drain the groundwater after a long time?

Yes! Absolutely! The "paper tree", an imported variety that has been planted in southern China, has almost absorbed the groundwater system.

Because of transpiration, the air humidity is guaranteed.

Water is recycled, and the absorption of water by plants is only an intermediate process. Transpiration, in turn, discharges most of the water into the air and returns to the ground in the form of rainfall.

Camphor trees are preferred, magnolia, eucalyptus, osmanthus, crape myrtle, wisteria, plane tree, luan, soapberry, locust tree, rhododendron, yueji, red sandalwood, metasequoia, red-leaved heather, cherry blossom, peach, etc.

What do you want to talk about, such as noise absorption, vacuuming, there are many kinds.

Single species, heavy artificial traces, lack of material and energy exchange, etc. The management is extensive.

The age of the mountain tip tree, the moving labyrinth.

It doesn't seem like a motorcycle, but I remember that one part was occupied by plants called "The Age of the Three-Pointed Tree."

The trailer for "Ruins". Is there a flying machine chasing the protagonist? Finally killed by the protagonist?

Plant growth regulator The plant itself has its own secretion of external anabolic growth and will not have any effect on the crop user Professional theory is that so far there is no Hehe We produce and sell plant growth regulator original drugs.

If it is used on crops, surrounding weeds may develop resistance.

It depends on the role of urban vegetation: absorbing carbon dioxide, releasing oxygen, and purifying the air (whether the increase in carbon dioxide leads to global warming, so does it have a role in regulating temperature); maintaining the balance of the ecosystem; Transpiration, which is the evaporation of water absorbed from the soil into the atmosphere, promotes the circulation of urban water. When the urban environment is comfortable, people are in a good mood.

The sea makes people open-minded, the sky makes people feel comfortable, and the grassland makes people have a heroic temperament... That's the power of nature. If you have nothing to do, go to the park for a walk, relax your muscles and invigorate your blood, benefit your body and mind, and it's definitely worth your money!

environment, noise, and the living environment of the original occupants.

Plane tree, privet tree, ash tree, boxwood, euonymus. Maple, ginkgo, begonia, cherry blossom, red leaf plum.

Meaty, small footprint, don't take care of it, give a little water a week, and don't grow worms.

The price is high and low, and you can buy many varieties of sedum for a few yuan.
