A tree lighter than a match stick is used by foreign countries to make airplanes, but our country has made thermos corks.

There are rich and colorful forest resources in the world, forest tree species are also extremely diverse, and forest trees are useful in many aspects of production and life. With the progress and development of science and technology, these trees have also played a greater role. Today, I would like to introduce a kind of tree, which claims to be one of the lightest trees in the world. Even a 3-year-old can hold its wood. This kind of tree has many uses, no matter it is abroad or foreign countries, it is inseparable from it.

This kind of tree is called Basha wood, commonly known as light wood, the reason why it is called light wood, because its weight is very light, although light weight, but light wood is one of the fastest growing trees in the world, in a year's time can grow five or six meters, ordinary trees will not achieve this rate of growth. Light wood is a species originally grown in tropical South America with heart-shaped leaves and large flowers that usually grow in the highest places of the trees. At the same mass, the weight of light wood is lighter than that of match sticks, because most of the match sticks in our country are made of poplar, which is more than three times heavier than light wood.

It is the lightest tree in the world, and ordinary women can easily carry light wood. It is precisely because of these characteristics that light wood has been used in many fields, and farmers have begun to plant it in Xishuangbanna, Yunnan, China. Dry light wood has a low specific gravity, so it is used to make life jackets. Light wood does not deform, the volume is stable, it is this unique characteristic that makes light wood shine brilliantly on foreign aerospace materials (sandwich panels). The earliest light wood planted in China was originally intended to be used in aircraft materials, but it was not successful in the 1970s. Later, it was made into a thermos cork to avoid waste.

Dry light wood features not only that, light wood can also be sound insulation and thermal insulation, which makes light wood in the furniture also occupies a certain position. Now light wood has been used in many fields, people just found these functions and demand of light wood, and began to plant light wood to meet the market demand. Now there are many farmers who gain great economic value by planting light wood, because the growth rate of light wood is very fast, and it is easy to survive, so the cost of planting is not big.

Really did not expect that there is such wood in the world, trees always give people the feeling is very heavy, did not expect that there is a kind of light wood. And now light wood has begun to come into people's lives, and the next step is to find the value of light wood in life. It is such a magical light wood, have you ever seen it? What other uses do you know of light wood?
