Scientific research has found that heavy metal and mineral oil are the two most important substances that cause pollution to soil. If we do not protect the land, the land that we human beings have rely on in ancient times may become wasteland. It will no longer be suitable for human living, nor can we provide the substances needed for human survival. Scientists have been looking for some plants that can repair the soil, and now they have some gratifying results. Below is a plant introduction that can be repaired in 5.
1. Indian mustard
As the international journal \"Molecular Science\" was published, heavy metals not only affect the industrial area, but also will also affect the industrial area, but also will also affect the industrial area, but also will also affect the industrial area, but also will also affect the industrial area, but also will also affect the industrial area, but also will also affect the industrial area, but also will also affect the industrial area, but also will also affect the industrial area, but also will also affect the industrial area. Pollution of land affects people's health. The cross flower species is very effective for gathering specific metals. At the same time, a large amount of biomass will be generated during the process, and Indian mustard is the first place.
It can remove more than 3 times more cadmium than other species, reduce the lead of 28 ｛BF｝, the decrease in selenium is as high as 48 ｛BF｝, and it is against zinc. , Mercury and copper are also very effective. But what we don't know is that in the 1980s, people used Indian mustard to remove reflected CS137 from Chelnobelli (used in Plants for Flooring soil in Ukraine Chelnobeli radiation).
2. Willow Tree
Xishui plant beautifying the landscape, but it should not be limited to their appearance. They also have the function of plant repair: their roots are powerful, lower than Indian mustard to gather heavy metals, and can also treat cadmium, nickel and selenium, survive in heavy metals like diesel pollution areas. You may remember the Westergasfabriek Garden of Amsterdam, which shows the casualness and repair characteristics of the willow tree through the pool and water botanical garden.
3. Popular tree
The favorable impact of poplars on soil and groundwater has been widely studied. Their secret lies in the root system and can occupy a lot of water.
According to the study of the national environmental health science institution, chloride solvents such as vinyl chloride or carcinogenic tetrachloride are organic pollutants, but hybrid poplars can respond well.
More importantly, the Canadian biological repair method database -PHYTOPET (biological repair function of aquatic and land ecosystems) marks poplar tree to degrade petroleum hydrocarbons, such And neighbors.
4. Indian grass
In the study, we saw how the soil and groundwater around the United States in the Midwest of the United States benefited. Many people can findIndian grass has been growing along the roadside, ignoring its ability to degrade ordinary agricultural chemicals, such as pesticides and herbicides.
Indian grass is one of the 9 family members divided by Phytopet, which is used to repair petroleum hydrocarbons. The list also includes other grass, such as common wildef grass or western wheat grass.
The experiment of the degradation of polygon aromatic hydrocarbon biodegradation in the sunflower root shows the ability of sunflowers to reduce the ability of polyconds in the soil, but it is truly What surprised people was that they gathered the breadth of the type of pollution.
Heavy metals such as lead, zinc (sunflower and rapeseed for heavy metal extraction), nitrogen, phosphorus, potassium, cadmium, copper, or manganese (corn, 苜蓿, and sunflowers grow jujube Coconut trees absorb heavy metals) as their food, which is great, because sunflowers can quickly grow.
In fact, an old plant of one month can remove the 95 ｛BF｝ uranium within 24 hours, showing their ability to remove reflective metals, such as removing 铯 and 锶 from groundwater. When the sunflower and other types are planted, some areas have great effects, such as abandoned mining areas.
In short, the earth is everyone, and the protection of the environment still has to start with each of us.
