At this time, Chu Jiaqiang's mobile phone rang. He brings a mobile phone, which is nothing more than to check the time, and the mobile phone does not go out, but is usually thrown in the room.

Ye Jisheng called, and as soon as he opened his mouth, he asked Chu Jiaqiang to hurry over, and there was a major news at the construction site of the school. Chu Jiaqiang asked what was going on, but the guy said to Chu Jiaqiang mysteriously, you will know when you come.

"What's the matter?" Ye Caiping saw Chu Jiaqiang hang up the phone, so she asked. Just now, she vaguely heard some of them, everyone will have curiosity, especially women, and the gossip is even more serious.

The second child called over and said that something had happened at the construction site. I don't know the specifics, the guy doesn't say. However, listening to his tone, it doesn't seem to be a bad thing. Let's go over and see first! Chu Jiaqiang said.

Every once in a while, he would go for a walk in the village with Ye Caiping, or go to Baimaping for a night to relive his relationship. This matter, everyone in the village knows, and many tourists are very envious of it, the real fairy life!

The two entered did not talk to the little fart child anymore, and the child who entered the house was already going to drive the two away in his heart. Just now, he was fascinated and couldn't stop, so he couldn't wait to get out of here.

At the construction site, here, the teaching area of the School of Chinese Medicine Revival has been built, and now it is just some finishing touches. As for the dormitory living area, that street is almost the same.

However, after the designer's design, it is ready to dig a lake at the door. This entry into the lake, yesterday has begun to excavate, just right, there are a few springs below, no need to bring water over.

"What's going on?" Chu Jiaqiang asked. He found that there were already many shortlisted viewers here, and many of them set up cameras to shoot the scene.

"There's a big stump dug down there, and it's going to take five of them. According to Hong Lao's observations, the big stump has been buried in the ground for more than 500 years. And the stump itself, before it was cut, it was more than a thousand years old. Ye Jisheng said.

"Ugh!" Chu Jiaqiang was speechless for a moment, just a stump, do you need to find such a big formation? I didn't know what to do, and I thought I had found a dinosaur fossil.

There should be a lot of such stumps in the village, at least, Chu Jiaqiang has seen several. It was all dug up by the villagers digging a pond, but it was not that big.

"It should be a cedar tree, right?" Chu Jiaqiang asked without surprise.

"Huh! How do you know it's a fir tree? Just now, the third child and Hong Lao also looked at it for a while before they were sure that it was a fir tree. The stump had been buried in the ground for more than five hundred years, and the bark and its vicinity had rotted, otherwise it would have been even more massive. It's unbelievable that a single cedar tree can grow that big. Ye Jisheng should have seen such a situation for the first time, so he was a little excited.

Chu Jiaqiang smiled: "What is this?" I had seen several tree stumps buried under the dirt, not so big, either pine or cedar. ”

Fir tree, whorl-branched, short internodes, twigs are relatively thick and oblique, and needles are short and thick on twigs. As a result, its canopy appears scattered. The pronunciation of the word "cedar" is similar to that of the word "san", and "cedar tree" is "scattered tree", which indicates a type of tree with a scattered crown.

Fir wood: straight texture, corrosion and insect resistance, widely used in construction, bridges, telephone poles, shipbuilding, furniture and craft products

Aspect. According to statistics, about 1/4 of China's building materials are fir wood. Fir trees grow fast and generally take only 10 years to reach maturity. It is one of the most important special timber species in southern China.

"There's no need to make a fuss, cedar trees are very long-lived, and in the deep mountains, there are many ancient trees that are hundreds of years old." Chu Jiaqiang said to everyone.

In the city, it is very difficult to find a native tree that is hundreds of years old, not to mention a thousand-year-old tree. There should not be many trees that are thousands of years old, even in the deep mountains and old forests, right?

"It's amazing! Buried in muddy water not only did not rot completely, but became harder. One tourist said in amazement.

They all saw the scene just now. The scoop of the excavator collided with the stump, making a sound of metal colliding. Later, Zhou Furong and others went down to check and found that the remaining stumps were as hard as steel.

"Didn't you say that cedar trees are easy to rot when they are wet in water?" Youjin asked.

"There are several kinds of cedar trees, and some of them do rot when exposed to water. But some, soaking in water will only be harder, especially this thousand-year-old tree, and the rest are the essence of the heart of the tree, which is very precious. Zhou Furong said.

"Isn't there something called metasequoia? What kind of cedar tree grows in the water and doesn't rot in the house? Ariri immediately said.

Because Metasequoia metasequoia was widely distributed in the Northern Hemisphere during the Mesozoic White and Cenozoic Eras, and after the Quaternary Ice Age, all other species of its genus were wiped out, so the discovery of "living fossil" Metasequoia metasequoia is considered to be one of the major discoveries in the contemporary plant kingdom. It is now widely cultivated and is a common garden tree species at home and abroad.

Hong Lao also nodded: "Yes, some fir trees are not afraid of water. In ancient times, the ancient people used cedar trees to build ships, and if they rotted when they encountered water, then they still had to do it? ”

In fact, there is a lot of wood for shipbuilding, which is generally taken locally, and the best of the best is selected. The material of cedar is relatively light, so it is naturally one of the selected woods.

Of course, the more famous ones are pine, cypress, teak and balsa wood.

A thousand-year-old needle pine column, ten years of sassafras trees are good to hit the boat! It means that the maturity period of the trees is different, and each has its own use. needle pine, needle pine, the stem is straight and straight, but it grows slowly; columns, house pillars, pillars of houses; Sassafras tree, with thick poles, can be cut into boards for shipbuilding, and grows quickly.

Millennial sea pine, 10,000 years of dry maple means that pine is not afraid of moisture, maple is not too dry. The bottom of the sea refers to a lot of water, damp, pine contains pine resin, so it is not afraid of water; Dry shelf, thousands of place, rest, with a bracket to support it, so that it is dry.

In addition, teak is one of the most valuable timber species in the world. The material is yellow-brown or dark brown, the wood is fine, the hardness is high, and the texture is beautiful. In the case of sun and rain, thousands of humidity changes greatly, it does not warp or crack; Water-resistant, fire-resistant, resistant to termites and sea insects in different sea areas, extremely resistant to corrosion, ranked first in the world's ship materials, is an important material for military navigation. At the same time, it is also an excellent material for the construction of harbors, bridges and other buildings, carriages, furniture, carvings, veneers, decorative panels and so on.

Hong Lao estimated a price for this stump, at least more than 500,000 yuan. So, the old village chief tried his best to get this hard bone up. This fund, the old village chief is ready to invest in education, which can once again reduce the burden on the villagers.

It only takes a second to remember this site
