What are the uses and hazards of eucalyptus?

1. Eucalyptus. It 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.

Eucalyptus has an average fiber length of millimeters, and its color, density and ratio of extract are suitable for pulping, and many large paper mills use eucalyptus to produce kraft paper.

and printer paper. Eucalyptus wood is mostly heavy and hard, and has strong resistance to decay, and can be used in construction, sleepers, pillars, piles, furniture, matches, farm tools, poles, fences, and carbon wood.

Introduction: Eucalyptus trees, also known as overlord trees, grow very fast, can grow 3 6 meters a year, so the demand for fertilizer is very high. It will deplete a large amount of nutrients in the soil, thus reducing the fertility of the soil.

As long as it is an environment where eucalyptus trees grow, it is difficult to see weeds. So the topic I want to share today is, what are the dangers of eucalyptus? Why.

1. What are the hazards of eucalyptus? Why.

Eucalyptus trees need a lot of nutrients and water to maintain rapid growth. Therefore, eucalyptus trees planted in the soil will cause the water level on the surface to continue to drop, and if eucalyptus trees are planted for a long time, the soil will appear desertified. Eucalyptus has extremely high requirements for nutrients, especially where eucalyptus trees are planted, soil fertility will be significantly reduced, which can easily lead to uneven distribution of nutrients in vegetation and lead to yellowing.

Eucalyptus itself is not harmful, but in the process of growth, eucalyptus will release harmful gases to the human body, which will make it difficult for the human body to fade. And the degree of water pollution is also very large, once the eucalyptus touched the water, after people or animals drink it, it will cause great harm.

2. What is the value of eucalyptus?

Eucalyptus can not only withstand high temperatures, but also low temperatures, drought, water, whether it is an alpine environment or a plain environment, eucalyptus can grow very well, so the requirements for soil are not very strict. And planting eucalyptus trees not only prevents soil erosion, but also purifies the environment and improves the climate. It also has a good effect on the control of wind and sand.

Planting more eucalyptus trees can effectively reduce the occurrence of the greenhouse effect. And in daily life, the chopsticks, furniture, and paper towels used are inseparable from trees. Growing eucalyptus trees avoids slow-growing trees that are cut down in large quantities, and eucalyptus trees grow particularly fast and can yield a lot of benefits from a single planting.

Therefore, its economic benefits are very good, eucalyptus also has a very important component, that is, eucalyptus oil, the substance extracted from eucalyptus oil, can be used as a regulator of grain, melon and fruit growth, has a promoting effect, and has a very important significance for agricultural production.

Eucalyptus can destroy the soil because it is a tree that requires a lot of water, if it is planted underground, it will reduce the amount of water, and then cause the soil to appear desertification, and eucalyptus has high fertilizer requirements for the land, if you plant eucalyptus, it will cause damage to the plants around it, eucalyptus will release a smell that is harmful to humans.

There are many hazards, such as planting for a long time, it is very likely to cause the water level to drop, it may cause soil compaction, it may cause the fertility of the soil to decrease, and it will release a particularly unpleasant odor, because this plant has a particularly strong influence on the soil during the planting process.

It affects the environment, it affects the atmosphere, it can cause soil erosion, it can cause drought in the land, it can affect the survival of living things. Because eucalyptus trees need a lot of water to grow, they also need a lot of fertilizer, which can cause this result.

Eucalyptus is used in many other ways, including construction, sleepers, pillars, piles, furniture, matches, farm implements, poles, fences, and carbon. Now the main use of eucalyptus is fiber utilization. It is used to make pulp materials, wood-based panels, etc.

Eucalyptus is a general term for the genus Eucalyptus in the Myrtaceae family, also known as white diesel tree, mangshu, galli, large-leaved eucalyptus, etc., the origin is mainly in the Australian continent, and it was introduced to all over the world in the 19th century.

Eucalyptus grows fast, and the material is also very good, and its use is also very wide, such as greening, wood, papermaking, etc. have extremely high value, eucalyptus, now mainly in Hainan, Guangxi, Yunnan, Guangdong, Hunan have planted.

Eucalyptus has a strong ability to sprout and regenerate, and can be cut down and utilized 2-3 times at a time of planting. By strengthening the tending and management of germination forests, the second and even third-generation eucalyptus germination forests can still achieve high yields.

The eucalyptus tree is very tall and tall, there will not be too many branches overflowing, it looks generous, and the leaves of the eucalyptus tree are also very beautiful, which is very suitable as a garden wood, which can be used as a beautification of the city's image.

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.
