In the past, it was a very common tree in the south, both wild and many planted by villagers, because it was a tree with high economic value at that time.
I believe that many people have seen it, but most people mention it is the first to think of its shortcomings, but they do not know that its value is very high, as a unique economic tree species in the mainland, the black tree has been cultivated in the mainland for more than 1400 years.
Do you understand its value, and why do you call it a "fortune tree"? Let's find out!
What kind of tree is the black tree?
When I was very young, my parents told me that there are two kinds of trees in the mountains that you can't touch or climb, the first is the sumac tree and the second is the black tree tree. In my local area, this kind of tree is also called "spicy tree", and it is a "pest tree" in many people's mouths.
The main reason is that there are a lot of spicy nuts on this tree, and when you pass under the tree in summer, you may lose a few spicy nuts. Being touched by it is painful and itchy, and this feeling is estimated to be unforgettable for many people.
In addition, the black tree is also poisonous, and when its branches are broken, a white sap will flow out, and it will itch on the body. If you can't resist scratching it, it will soon swell.
It is understood that the reason why the black tree has such a strange name is because after this kind of tree is old, the roots of the tree will rot into a mortar, after the changes of the times, people add a wooden word next to its mortar character, and it has evolved into today's "black tree".
But many people don't know that it is an economic tree species unique to the mainland, it is a woody plant belonging to the genus Euphorbiaceae, and it is called a wax tree, a tree tree, or a wood tree in the folk.
This tree is also divided into the black tree and the mountain black tree on the mainland, and the difference is also obvious, the former is an arbor, up to 15 meters high, and each part is hairless and has milky sap.
The mountain black tree is a tree or shrub, generally 3-12 meters high, rarely up to 20 meters, all parts are hairless. Hence hairy and hairless are their main differences.
It is very tenacious and adaptable, preferring to be born in the wilderness, by ponds or in loose woodlands. It is not afraid of the cold and heat and can thrive even in harsh environments.
In addition, it also prefers sunny places and is not shade-tolerant, which allows it to find its own living space in a variety of environments.
What is the value of the black tree?
In the past, it was an important economic tree species unique to the mainland, especially before the arrival of the industrial age, and this kind of tree was widely planted in many places in the south, and it was also called "fortune tree" by the villagers.
In the folk, there are "thousands of brown trees, ten thousand trees, not as good as a black tree." "It is said that even if you plant a thousand palm trees or 10,000 paulownia trees, it is not as good as planting a black tree, which also highlights the high value of the black tree, so what is its use?
First of all, the black tree is widely used in the industrial field, which is why farmers used to grow it. The wax on the outer coat of the seeds of the black tree is "Quercus wax", which can be used to make "skin oil", which is an important raw material for making high-grade soap, wax paper, candles and other items in ancient times.
The oil content of its kernel is very high, and the oil extracted is called "eucalyptus oil" or "green oil", which is one of the main raw materials for paints and inks in the past. In addition, after its seeds are extracted from oil, it is also a good waterproof coating, and it was often used to apply oil paper, oil umbrellas, etc. in the past.
You know, in the past, these were common things that every household had. In the past, many farmers planted the black tree in order to take its fruit and then process it into various raw materials, which has a high economic value.
Secondly, it is also a very important wood. The black tree has strong vitality and does not grow slowly, and its wood is white, dense and hard, and has the characteristics of fine grain, no warping or cracking.
Therefore, in the past, it was also a high-quality wood for making items such as vehicles, furniture, and carvings. In ancient times, black tree wood has been widely used in the production of various buildings and handicrafts, and its unique texture and texture are deeply loved by people.
Again, it is also a natural dye. The leaves of the black tree are pure natural black dyes that can be used to dye clothes. In the past, cloth was made in many places by dyeing it with the leaves of the black tree.
Fourth, the medicinal value is also very high. This is also an extremely important value of the black tree, whether it is in medicine, veterinary medicine, or agriculture, etc., the black tree has a high value.
For example, in the past, the leaves of the black tree could be used as feed for fish, and its leaves also had the effect of treating fish diseases. In addition, in many ancient medical classics, there are records of the medicinal value of black tree.
Finally, the garden value of the black tree is not low. Nowadays, many parks, communities, or urban roadsides will also plant black tree trees, also because it is easy to grow and has the advantage of high ornamental value.
It is loved for its beautiful landscape with neat canopy, beautiful leaf shape, and autumn leaves in full swing when the autumn leaves are frosted. It can be planted not only as a street tree and ornamental tree in public places such as parks and streets, but also as a garden tree in private homes, bringing people the enjoyment of beauty.
It is worth mentioning that the cultivation and utilization methods of the black tree were recorded in detail in the ancient works such as "Qi Min Yaoshu" and "Agricultural Administration", which shows its important position in the society at that time.
In modern society, with the progress of science and technology and the improvement of people's living standards, the utilization value of black tree is more prominent. With the deepening of the research on the black tree, it is estimated that it will better benefit our human beings.
