Never die for a thousand years
Generally speaking, the life span of Hu Yangshu is about 100-300 years, and the longest is only 500 years, while there is almost no life span in Hu Yangshu over 500 years. Due to the special properties of plant genes, Populus euphratica has strong adaptability to saline-alkali and arid environment, and can grow well in arid desert only by absorbing a small amount of water.
On the contrary, if Populus euphratica can't grow in hot and humid tropical or subtropical climate or loose land, but Populus euphratica is not only drought-resistant, but also cold-resistant, so Populus euphratica can still survive in the Gobi at a low temperature of MINUS 40 degrees Celsius. However, due to the limitation of plant cells, Populus euphratica will basically end its glittering life in about 200 years.
Will not fail for a thousand years after death.
This is also related to the basic properties of Populus euphratica, because Populus euphratica itself is less dependent on water, so the trunk of Populus euphratica has less water content. In addition, in the desert Gobi environment, there is less water, so the root system of Populus euphratica is particularly difficult to rot, which is also the reason why Populus euphratica is tall and straight.
However, Populus euphratica is also a drought-resistant plant. No plant can grow without water, so there is a little water around Populus euphratica. Therefore, the root rot of Populus euphratica is slow and can last for a long time, but it is not as exaggerated as "once in a thousand years". It will take decades!
After a thousand years, it will not rot.
Because the living environment of Populus euphratica is relatively dry and the wind and sand are relatively large, Populus euphratica will be covered by wind and sand after falling down, below the shallow surface. Coupled with the low rainfall in the desert, generally only heavy rainfall can penetrate Populus euphratica. In this case, Populus euphratica will be under the dry surface for a long time, reducing direct sunlight, so the decay of Populus euphratica will be relatively slow.
In a word, "Populus euphratica lived for a thousand years, died for a thousand years, lived for a thousand years, lived for three thousand years, and had a history of one hundred million years" is only used to praise Populus euphratica for its courage, perseverance and self-improvement, but it does not mean that Populus euphratica really has such a long life.
