The development of science and technology often brings about a variety of process adjustments, in the early development of a lot of things are dependent on manual action, and the manufacture of many things needs to consume more time and energy, but with the progress of manufacturing technology and people find more raw materials to make the manufacturing process relatively simple.
Even so, some of people's dependence on nature is still very obvious, like everyone's current food and clothing is partly from natural trees, and of course, in addition to trees, there are some things that deserve everyone's attention, that is, bark.
The bark of many trees can make things, just like the paper and some tools that everyone uses in work now are made in this way, and in addition to these, some of the bark of Chinese trees can be used for medicine and even edible, but we are going to talk about portugal today.
What's going on in Portugal, which has been skinning their trees all along and getting soft gold from this process?
In fact, there is only one species of tree peeling in Portugal, that is, soft oak, and there is actually a lot of attention to the bark of this kind of tree.
Because the bark of soft oak is very thick, it can reach a thickness of about 30 cm, and due to its own growth, its appearance looks rougher, but softer and lighter. Such advantages provide a certain advantage for the overall growth of soft oak, and these barks are now very common red wine bottle stoppers.
As a result, the bark of these plucked trees has also become soft gold, and due to Portugal's unique climatic location, the soft trees here grow very well.
However, the growth of soft oak requires a relatively long cycle, so the reason why their industry can rise now is that they developed earlier, coupled with geographical advantages, so that their soft like trees also grow better.
There are also many regulations about the harvesting of soft oak bark, soft oak is a national treasure in Portugal, so there are also many requirements for wanting to pick up the bark of a national treasure.
Generally speaking, soft oak can only be peeled with a diameter of more than 70 centimeters, and in addition to such tree requirements, it can be peeled every nine years, like these requirements are more stringent, but after all, it is for better development, plus Portugal has more planting on soft projects, so even if the interval is long, they can grasp such production.
Every year Portugal exports and sells a lot of red wine stoppers, which are derived from these cork oaks.
Of course, in addition to these, this industry also has a drawback, that is, the first and second years of the soft oak bark reaching the diameter are almost useless.
Because such bark cannot meet the standard, it cannot be directly made into a product, so the bark harvested in the first and second years is almost useless.
Bark is useful nature is what everyone is happy to see, so pick up the bark, will it be harmful to the growth of trees? Some of the nutrients of soft oak are mainly based on a layer of bark called phloem inside the bark, so special care will be taken in the process of mining and harvesting, and only the outer layer of bark will be cut off, so the Portuguese soft oak bark harvest season is very busy every year.
And a soft oak tree needs two people to cooperate to complete the harvest at the same time, which is also a necessary condition for the development of this industry, so the difficulty is also relatively large.
In fact, China also has to pick up the bark to sell, so if there is such a way, then why doesn't the mainland grow soft oak?
In fact, one of the main reasons is that the water and soil are not satisfied, and the planting conditions of soft oak in Portugal are very good, so they grow faster and the bark obtained is also more advantageous.
However, there are relatively few areas in China that can meet their growth, and even if they are planted, there are fewer soft projects that can be used for commercial use.
Therefore, there is no way to introduce such a way in China, after all, it is a geographical reason, there is no way to make other changes, although Portugal can pull out soft gold for the bark of the tree, but this way is that the mainland cannot be directly transplanted.
But China has another advantage of picking bark to get rich, that is, cinnamon, about this kind of peeling, China has also done it for many years, and if there is no way to do it on soft oak, then we should pay more attention to the cinnamon that belongs to China, after all, the water and soil conditions are something that humans can't change, if you want to change these to complete an industry, invest too much money, and it seems unnecessary.
Each country has its own development advantages, these advantages are encounterable and unattainable, and since these are not suitable for China, then China can find another way.
