Afforestation is a well-recognized means of protecting the environment, yet there is a tree in our country that is not only not protecting the environment, but has also been branded with a lot of ugly labels, such as the “springer”, the “hopper tree”, the “cracker tree” and so on. Is it really “toxic” to the environment, as many people say
The eucalyptus were introduced
In fact, the apricot tree that was first introduced into our country has been referred to as the “shaking money tree”, because it is a fast-growing tree with very high economic value。
Guangxi was the first region in the country to have been established, in 1890, that is, more than 130 years ago, when the first small plant of eucalyptus was planted in longzhou county, guangxi, china. Because guangxi has a good ecological environment, the footprints of eucalyptus are soon visible in a wide area of guangxi, and scientists soon discovered their economic value。
In terms of the economic benefits of farmers alone, eucalyptus are growing at a very high rate, with very high returns from planting them. This is mainly related to the growth properties of the eucalyptus. Elm trees, which are common in warm temperate and tropical areas, are warm, wet and well-developed and are able to absorb nutrients and moisture from the soil quickly。
As a result, eucalyptus tend to grow in three to five years, and can be cut two to three times. Its alternative crop, the pine tree, takes 10 to 20 years to produce its material, and it cannot be re-emerged after cutting and can only be replanted。
Moreover, the pelican trees do not need to repair branches and the cost of conservation is extremely low, thus saving farmers much. Some farmers are mainly land-fed and grow some aluminum trees in the mountains, which are subsidized by the government and used as a side business to raise household income. Others planted eucalyptus trees in their homes, so they went out to work and could be sold in a few years。
The planting of eucalyptus is not only beneficial to farmers but also leads to other employment. Our eucalyptus industry has generated 5 million jobs, ranging from logging workers and wood processing to furniture consumption, supporting 300 billion yuan。
A worker can make 50 dollars to cut a ton of trees and at least 300 dollars a day, from the point of view of production. From the processing point of view, the growing trunks of eucalyptus are large, straight and easy to process, and production costs are significantly reduced and are well suited for selection as wood。
According to statistics, the annual production of guangxi timber in 2017 was 3. 059 million cubic metres, the country's first largest production, of which approximately 70 per cent were aluminum. Winning aluminum wood in quantity is much cheaper than pine and herring wood。
Thus, from a consumer's point of view, if there were no aluminum trees, china's timber prices would be at least three times higher than the current ones, and housing prices could also rise, as much of the construction industry would require large amounts of wood。
"toxic" of apricot trees
Even though aluminum has so much economic advantage as a commercial forest, it is still referred to as a “water pump” as a “defeating tree” and a “breeding tree”. This is reflected mainly in the fact that the planting of eucalyptus is accompanied by numerous environmental damage。
“pumper”
Owing to its brutal growth patterns, the apricot tree is in great need of water, and many people will see areas that have been planted, including reduced groundwater tables and soil salination. The amount of water required for large areas of apricot forests is indeed very large, not to mention the amount of groundwater they absorb from their thick roots, but to say that they absorb water from the air。
A birch tree, planted for two to three years, absorbs 4-5 litres of water in the air in one day, which results in a severe reduction of local precipitation, and if large areas are planted, it can even cause drought, which can lead to the desertification of the land。
"the deutsche tree"
In places where euphemism grows, weeds and bushes are almost invisible, and many argue that euphemisms inhibit other species, leading to the non-existence of other plants and the destruction of biodiversity. Even the eucalyptus are considered to be toxic in themselves, such as the toxic water from the eucalyptus tree, the toxic leaf of the eucalyptus, and the death of fish in the water of the eucalyptus within a minute。
If the eucalyptus were truly toxic, the plant and animal that would have lived in the area would have died in large numbers, even in the eucalyptus. In this logic, the euphoria seems to be truly a “demeanor tree” for personal gain。
"the tree of the broken child"
Episode trees themselves are able to absorb the fertilizer in the soil in large quantities, so that in many places they can be fertilized when they are grown, making them grow rapidly and yield higher economic benefits. However, this has resulted in soil degradation and the blacking of surrounding water pollution. In a wide variety of areas that have crossed the forests, the soil has become infertile and has been unable to grow other crops for long periods of time, plaguing future generations ' agricultural cultivation. In addition, in areas where eucalyptus are growing, the surrounding water sources become darker and fish shrimp die in large numbers, among other reasons, the eucalyptus trees are referred to as “breeding the seed trees”。
From the above three points, if a large area is planted in an area, it is likely to cause serious damage to local water, soil and biodiversity. This method of production, which uses the resources and land of the future in exchange for the economic benefits of the short time available, is indeed terrible。
But is it really toxic? Is it really such a great danger to the natural environment
Is it really poison
To be clear, the growth pattern of the apricot is indeed very rapid in absorbing moisture and soil nutrients, and it is a true hegemonic tree. But the damage to the environment by naturally growing eucalyptus is not so great, and it is the wrong way to plant the apricot trees。
In fact, if it is grown from the reserve mountains, it is only three or five acres, once a year, once a year, once a year, once a year, and once a year, it can earn $230,000. There are still a lot of weeds under the forest, and there are no more cattle to eat, and there is no water pump in guangxi with abundant precipitation. A lot of people pack dozens of acres and grow them to sell 3. 5 million for years。
However, when the eucalyptus industry is favoured by some capital companies, they encourage farmers to grow large areas of eucalyptus through subsidies. In order to prevent weeds and other trees from exploiting the moisture and nutrients required for the growth of euphoria trees, many areas have begun to burn and deforest the mountains before planting them all over the mountains. If weeds grow, we spray herbicides and pesticides in large quantities, so we often see no other plant growing under the apricot trees。
In order to maximize the economic benefits of fast-growing eucalyptus, large-scale fertilization is also common to them. Chemicals in fertilizers and pesticides enter rivers and lakes and contaminate nearby water sources. So it's not the apricot, it's the fertilizer that makes the water darker and the shrimp die。
Over the years, guangdong, guangxi and fujianland have begun a “prohibiting order”, which does not mean a total ban on the cultivation of euphemism, but rather a ban on the widespread cultivation of live grasshoppers。
In its response to the recommendation on the harm of cultivation and prohibition of cultivation of elm trees, the forestry department of guangdong province made a number of specific requests for the cultivation of euphemisms: to combat resolutely the violation of the destruction of natural and ecological public goods for the planting of euphemisms, to adopt scientific business measures, to promote the construction of mixed forests and to avoid predatory practices; and to promote, inter alia, the improvement of soil through the mixing or rotation of nitrogen-fixed trees。
As guangxi, the prefecture of el niño, which accounts for 14 per cent of the total area, produces 80 per cent of the region's wood, contributes 40 per cent of the country's wood to 0. 6 per cent of the country's forest land, supports 300 billion yuan in wood processing and sequesters more than 40 million tons of carbon annually。
To be honest, this is not a proud figure, as many farmers who grow eucalyptus are not only making little money, but are also being criticized and blamed. Guangxi, one of china's most difficult provinces, has a very large rural population, but the land is so barren that it does not produce good-quality crops, and the planting of eucalyptus is almost the path to survival for many families。
When pelican cultivation is problematic, we should think about how to protect the environment without compromising the interests of farmers, rather than simply denying the value of the pelican tree and depriving others of their right to produce a living。
