Why are precious wood mostly produced in the south and less in the north?

Because most precious trees grow in the south.

Taking red oak as an example, the wood in the northern producing area is relatively uniform in color, light in color and small in chromatic aberration. The probability of mineral grains in wood is small, the trees are not as thick as those in the south, and the grains are smaller than those in the south.

Due to the cold climate in the north and the slow growth of trees, the stability of wood in use is extremely strong, and the phenomenon of cracking and deformation after wood is made into furniture is less. Because the color is uniform, it is also convenient for wood products to make light paint.

Taking red oak as an example, the southern producing area has a warm climate, abundant rainfall and rapid growth of trees. The typical characteristics of southern wood are that the board is generally wider than that of northern wood, the board color is obviously red, and the texture is larger than that of mountain wood and northern wood.

Extended data ①? When stimulated by trauma or fungal infection, the core of Daphne plants will secrete a lot of resin with strong fragrance. These parts are also called "water agarwood" because of their high density. When burning, the smoke gives off a strong aroma and black oil seeps out.

(2) Aquilaria sinensis will go through a long growth period, which will take at least several years to more than ten years. However, a high-quality Daphne plant takes decades or even hundreds of years to form, so the output is very small and the market is in short supply, so it is very precious and has high collection value.

(3) There are many kinds of Daphne, which can be divided into three types according to the oil content: submerged type (this is the essence or middle part of Aquilaria sinensis, and it is also the part where the paste condenses tightly and firmly, and will sink when thrown into the water), raft type (semi-floating and semi-sinking) and yellow ripe fragrance type (not sinking in water).
