What are the dangers of eucalyptus? What are the hazards of eucalyptus?

1. Eucalyptus is a fast-growing and high-yield forest, with high water demand, planting in the soil will reduce the groundwater level, and long-term planting will cause soil compaction and desertification.

2. Eucalyptus has high requirements for fertilizer, and where eucalyptus is planted, soil fertility will decline a lot, resulting in insufficient nutrients in the original vegetation and death.

3. Eucalyptus itself is non-toxic, but it will release a harmful odor to the human body, and it is difficult to remove it. In addition, it will also be extremely polluting to water, and people and poultry will cause certain harm after drinking.

Most of the varieties of eucalyptus are tall trees, a few are small trees, and few are shrub-like. The canopy shape is spire-shaped, multi-branched, and weeping-branched. Simple-leafed, entire, leathery, sometimes covered with a thin layer of wax.

The leaves can be divided into three categories: juvenile, mesophyll, and mature, and most varieties have opposite, smaller, heart-shaped or broad-lanceolate.

There is no harm in itself.

1. However, the hydrocarbons containing rubber matrix released by eucalyptus combine with carbon dioxide to form ozone.

2. It has high requirements for fertilizer, which can overabsorb nutrients in the soil.

3. The water demand is very high, which can make the outburst soil compact.

One is that the chemicals used in the growth of eucalyptus trees are very polluting to the environment. On the other hand, where there are eucalyptus trees, other plants will be relatively disadvantaged when they grow. Another is that eucalyptus trees have a huge demand for fertilizer, which is likely to degrade the land.

Desertification occurs. Eucalyptus trees are fast-growing and highly productive, require a lot of water, and planting in the soil will lower the water table.

Large-scale planting of fast-growing eucalyptus requires a large number of nutrients, which can easily lead to barren land, soil fertility decline, land drought causes the degradation and death of native species, seriously damages the ecological environment, underground rivers, and streams dry up and cut off. According to the authoritative opinion of the Institute of Eco-Environmental Sciences of the Chinese Academy of Sciences, the Southwest Forestry University of China and the State Forestry Administration, the harm of planting eucalyptus trees in large areas is very great.

Eucalyptus has a great demand for fertilizer and nutrients in the soil, where eucalyptus is planted, the fertility of the land decreases or even depletes, and the original vegetation is seriously damaged because of the lack of sufficient fertilizer and nutrients, causing land degradation, deterioration of soil and water conservation, and the land is barren, and other plants can not survive at all.

Eucalyptus will secrete a chemical substance, which will inhibit and repel the growth of other plants, so that the plants under the eucalyptus tree cannot grow, and it has great inhibition on the local native, native and native species. If it grows, other species will not be able to grow, and the ecology will be subversively damaged and difficult to recover.

Introduction to eucalyptus

Eucalyptus, also known as eucalyptus, is a tall and evergreen tree. The vast majority of eucalyptus trees are native to mainland Australia, with a few growing on the islands of New Guinea, Indonesia and the Philippine Islands.

Hazards of planting eucalyptus

1. Bumping leads to a decrease in land fertility. Due to the high demand for fertilizer and nutrients, the fertility of the land on which eucalyptus trees are planted is generally reduced or even depleted.

2. Inhibit the growth of other plants. Because the growth of eucalyptus is very domineering, the nutrients of other plants will be robbed by eucalyptus, so eucalyptus will destroy a certain ecology.

3. Resulting in soil drought, eucalyptus not only has a greater demand for fertilizer, but also has a greater demand for water, which will lead to drought or even cracks in the land.

1. Soil compaction: Eucalyptus will absorb groundwater resources in the process of growth, resulting in soil water shortage and compaction. 2. Polluted water sources:

Eucalyptus emits a toxic gas that can merge with water and affect the health of people and livestock. 3. Reduce vegetation: Eucalyptus will compete with other vegetation for nutrients, resulting in the death of vegetation due to lack of fertilizer.

1. Soil compaction

Eucalyptus is a fast-growing plant with a greater demand for water, and in the process of growth, the root system will penetrate deep into the soil layer and absorb the groundwater resources accumulated in the soil, resulting in a drop in the groundwater level, and long-term planting will reduce the content of groundwater and make the soil compact.

2. Polluted water sources:

Although eucalyptus itself is not toxic, in the process of growth, it will release a toxic gas, if the eucalyptus tree is planted close to the water source, the toxic gas emitted will be integrated into the water, and after people and livestock drink it, it will cause harm to health.

3. Reduce vegetation

Eucalyptus is a plant that requires a lot of fertilizer, and after planting, it will use its root system to continuously absorb nutrients in the soil to maintain its own growth, and over time, it will cause other vegetation in the planting area to die due to lack of fertilizer, thereby reducing the number of vegetation.

The smell of eucalyptus is very strong, which is very harmful to the human body, and the place where eucalyptus is planted cannot be planted with other things for a long time. Eucalyptus trees need a lot of water due to their fast growth, and once a large area of eucalyptus is planted, the water requirements are very high, and in severe cases, the water level of a large area will drop. Eucalyptus trees require a lot of fertilizer to grow, and if they are not fertilized, the soil will lose nutrients severely, and other organisms will not be able to continue to grow.

1. The smell of eucalyptus is very great, which is very harmful to the human body, and the place where eucalyptus is planted cannot be planted with other things for a long time, especially if there are no people living nearby, because it will be harmful to people.

2. Eucalyptus trees grow very fast, so they need a lot of water, once a large area of eucalyptus is planted, the water requirements are very high, and when it is serious, it will lead to a large area of water level drop, in the place where eucalyptus trees grew in the past, drought often occurs, because eucalyptus trees will absorb the water in the land!

3. Eucalyptus also needs a lot of fertilizer to grow, and if it is not fertilized, it will lead to serious nutrient loss in the land, so as long as the eucalyptus tree has grown, other organisms can no longer continue to grow, because there is no nutrition.

4. Eucalyptus will inhibit the growth of other organisms, the vitality of eucalyptus itself is very tenacious, as long as the water and fertilizer where eucalyptus grows will be absorbed by eucalyptus, and other species have no chance to absorb nutrients, so eucalyptus is a very invasive alien species, and it is generally forbidden to plant eucalyptus trees in a large area in China.
