What are the five colored soils in China? Distributed there

Five-color soil in China refers to pure natural soil with five colors, namely green, red, yellow, white and black. The distribution is as follows:

1. Black soil: mainly distributed in the northeast plain of China. Because it is wet and cold, the microbial activity is weak, and the organic matter in the soil decomposes slowly and accumulates a lot, so the soil color is dark.

2. Loess: It is mainly distributed in the Loess Plateau of China, where the soil is yellow, which is due to the low content of organic matter in the soil.

3. Red soil: mainly distributed in hilly areas south of the Yangtze River, including most of Jiangxi and Hunan, southeastern Yunnan and Hubei, northern Guangdong and Fujian, parts of Guizhou, Sichuan, Zhejiang, Anhui and Jiangsu, and southern Tibet.

4. Blue soil: It is mainly distributed in the eastern part of China, because under the condition of poor drainage or long-term flooding, the iron oxide in red soil is often reduced to light green ferrous oxide, and the soil becomes grayish green, such as some rice fields in the south.

5. White clay: mainly distributed in western China. Saline soil and alkaline earth with high salt content such as magnesium and sodium are often white.

On traditional five-color soil;

"Five-colored soil in China" is a soil with five different colors, namely green, red, yellow, white and black, selected from five directions of China. This means that the "land of five colors" represents the whole land of China, and implies that the territory of China is vast and colorful. "Five" is a special number in China traditional culture, "Nine" is the largest number of days and "Five" is the largest number of digits.

In all fields, there are five basic elements "five" which represent the whole and cover the whole. It is no longer a simple concept of numbers. Traditional culture holds that five substances "wood, fire, earth, gold and water" are the basic elements of everything in the world, and these five elements are called "five elements".

Five colors, five prescriptions, five tones, five flavors and five elements are corresponding to each other. The unity of opposites constitutes a whole, and these mysterious corresponding relations are the understanding and description of nature by Chinese ancestors. From these traditional cultures, we can feel the profound wisdom of our ancestors in understanding nature.
