Wood is buried in the soil for a long time because of stratum change, which is called? Black wood? , also called what? Yin Musha?

It is a general term for all kinds of wood that has been buried underground for a long time without decay. These Woods are characterized by moisture-proof, insect-proof, anti-corrosion, fragrance and heavy oil. There are many kinds, mainly cypress, Chinese fir, nanmu, Fraxinus mandshurica, wild litchi and bitter.

Catalpa, Phoebe bournei, Tieli, etc. Dark wood has different names in all parts of the country. It is called "Langmu" and "Shuijiangmu" in the Songhua River Basin in Northeast China, and "Ebony" in Sichuan (the main hidden wood is generally dark in color).

In addition to the classification of tree species, there are several reasons for the formation of dark wood:

Submerged in river sediment, trees are generally washed into the river by geological disasters such as mudslides and soil erosion in the upper reaches and buried in the river bed; 2. Burying of trees caused by earthquake; ?

3. Coffins buried underground for several years.

In China, ebony is carbonized wood, which is called ebony by Shu people and "Oriental Shenmu" by westerners. Blackwood has a long history. According to the available data, in ancient times, rare ancient trees in virgin forests suffered sudden and significant geographical and meteorological changes (such as earthquakes, flash floods, lightning strikes, typhoons, etc.). ), some are buried under the mud and sand of ancient river beds and rivers and lakes, and some are buried in the dark strata that have been deprived of oxygen for thousands or even thousands of years and washed by rapids. After thousands of years of natural abrasion, this dark wood has both the elegance of wood and the charm of stone. Its texture is solid and heavy, its color is black and luxurious, its cut surface is smooth and delicate, and its wood is oily, moisture-proof and fragrant, which will not rot for thousands of years and is not afraid of insects. Individual tree species recorded in ancient books also have medicinal value. It combines the characteristics of "thinness, permeability, leakage and wrinkle" and is worthy of the reputation of "Oriental Shenmu" and "plant mummy". ?

Blackwood has been regarded as a precious wood and a rare thing since ancient times, and it is a symbol of dignity and status. There is a folk saying in our country that "a box of jewelry is not as good as ebony" and "20 thousand gold is sent to the underworld for ebony to worship the spirit of heaven" In ancient times, dignitaries and literati regarded furniture made of black wood and works of art carved from black wood as family heirlooms, treasures of towns and houses and things to ward off evil spirits. Throughout the ages, especially in the Ming and Qing Dynasties, black wood became the first choice for emperors to build palaces and make coffins. In the Qing Dynasty, the emperors even listed it as a special material for the royal family, and the people could not use it privately, which made this kind of black wood even rarer. Yuan Shikai, a traitor in the Republic of China, went against the historical trend, and the "Emperor Dream" soon died. However, in order to show that he was an emperor, his family tried their best to find a gloomy wood and put together a coffin for him. Although this is a historical joke, it also shows that the preciousness of heavy wood is hard to find.
