There is a clear distinction between a forest that is maintained by people and a forest that is not maintained. \\\ Eliminated plants will quickly make room for new species.
In recent years, some of the small trees that have been cut down have been of little use and have been crushed into sawdust by machines.
Then even the cultivated strains are not used, and they are directly compressed into small particles.
The rangers always take some with them when they go out and throw them in the forest.
Researchers are more likely to look for some edible mushrooms in the wild.
Instead of being cultivated in a laboratory.
The laboratory is more about testing and studying how to use it.
Because the whole forest is such a large natural culture medium, the laboratory can't catch up with it anyway.
As for the population of microbes that can eat pollen, He Xiaomin said now is not the time.
Now there are them, but they can't fly.
In addition to having enough organic matter in the air, there also needs to be enough humidity.
Shennongjia is affected by the alternating influence of the hot and humid southeast monsoon and the dry and cold continental high pressure throughout the year, coupled with good forest vegetation, and the precipitation is relatively abundant.
However, it is still not enough to support the proliferation of this microorganism.
And it's not enough for any one place.
The Xiaolingya generation is still mostly secondary forests, which do not belong to the primeval forest.
If you want to see the microbial community that the rangers call "spiritual soil" or "false soil", you have to go inside.
It is a real primeval forest, and the number of species has been artificially increased by forest rangers.
At the forest level, for example, there are seven to eight layers of canopy in the primary forest, and some ancient trees are still growing taller thanks to artificial maintenance.
Some have reached more than a hundred meters in height.
They all have a thousand-year-old history.
This is not comparable to a decades-old tree like Xiaolingya.
He Xiaomin said while taking Zhang Chun and his wife inside.
"It is said that when Wudang Mountain was built.
The emperor sent people to cut down trees here, and it took three years for a tree to be cut down and transported to Wudang Mountain.
A single stump can carve a big Buddha.
The largest tree we are surveying now occupies a hill alone.
The entire canopy area is larger than the hills below. ” Zhang Chun was also stunned when he saw this big tree.
"This cedar tree grew later, and if I didn't know about this stump, I would have thought it was a hill, and I thought it was three cedar trees instead of one.
The hill below him is supposed to have been formed by its roots arching the ground.
However, the heart of the tree is empty, and I don't know how many years have passed, and it has been filled with soil.
There are more than 4,000 species of plants living on this tree alone.
We built three observatories on the trees. ” Each of these three big trees cannot be surrounded by ten people.
In later generations, there were no such big trees.
Because it was chopped off.
But that's thousands of years, and then there's only a few decades left.
Human beings are so shallow, "There are a lot of these old trees in this area, just because of the different tree species.
Although they are more than 1,000 years old, they vary in size.
This cedar tree is the largest and is the king of the forest in this area. ” A trestle bridge built along the middle of three large trees.
Walking up, there is indeed a feeling of overlooking the world.
At the bottom, it's too hidden.
So it's all bryophytes and some shade-tolerant species.
But the higher you go, the more plant species you go, not only do not decrease, but increase.
More than 30 meters, it is the place with the most dense plants and the densest fog.
Many parasitic plants have aerial roots, dense like a jungle in the air.
As far as the eye can see, it is full of flowers.

"The spiritual land lives on this layer, and there is no further up.
Because there is not enough moisture.
You see, that is.
Now they can't fly.
It's just attached to the aerial roots.
But with the arrival of flowering throughout the forest, precipitation and fog increase from May to September.
They begin to multiply in large numbers. ” "Actually, we call these things false soil, and you see they have some plants growing on them.
Formed a wonderful little environment.
This is the result of millennial evolution, and once destroyed, it cannot be restored. ” False soils, the term is more accurate, in fact, they and aerial roots form a layer of plants in the air, and some plants that used to grow on the ground now grow in this space about five or six meters thick.
It's like a legendary fairyland, but it's a little smaller.
"Further up, if the air and moisture conditions are insufficient, the plant species will decrease rapidly.
However, due to more than ten years of maintenance, the thickness of this layer is increasing.
It wasn't so thick before, only a thin layer.
Cannot be noticed.
But in recent years, the dead trees in the forest have disappeared, some trees are growing taller, more than 2,000 species have been introduced, and the flowering period of the forest has been extended.
The ability to conserve water is also increasing.
It was the rapid increase in the thickness of this layer that caught our attention. ” "Xiaomin, are you here?"
More than ten meters above, between the three branches, a platform was built with wood.
Two girls poked their heads out of it and looked down.
This platform is not small, in addition to the house where people live, there is actually a small balcony, planted with some flowers and plants.
There is also a water tank on the balcony, and a plastic pipe climbs up the trunk of the tree to pump water.
The hut had been built for some time, as it was covered with vines.
The timber from which the platforms and wooden houses were built has been treated with antiseptic treatment and has not deteriorated over time.
The wooden house is also very sturdy.
It's just that in addition to telescopes and microscopes, there are only some basic living facilities inside, which is very simple.
The cabin has solar panels on top and a battery pack in the room.
But electricity is only enough for lighting and pumping.
He Xiaomin is not in charge of this area, but because he was in the environmental institute, he met the little sisters here.
So it's good here.
But soon the sisters on duty above laughed at He Xiaomin.
Because Guo Bin is too gentle, he will be shy when he sees girls.
Along the way, he kept silently following behind He Xiaomin and didn't talk much.
He is now fully armed, and he can't go this far without being fully armed, because he can't go this far on his own ability.
It was near Xiaolingya, and he also traveled with his eldest brother.
The two girls were not surprised by Zhang Chun and his wife, and the discolored equipment was the symbol of the Special Scout and the Dark Moon.
Zhang Chun's family liked this place almost instantly, because the air here was better than ever.
But Zhang Chun also knows that this is the result of thousands of years of accumulation, and in other places, even if it is properly maintained, it will not be possible to achieve such an effect without decades or centuries.
Fairy, the plants in that area are pureer, but those plants have to grow like this, and the plant species should reach so many.
I'm afraid it will take more time, and it won't take one or two generations to complete.
Shennongjia is indeed blessed, after thousands of years of optimization and evolution, it is blessed.
It's just that the species are mixed, and some of the breath in it can be tolerated for a short time, but it won't work after a long time, and that is the smell of decay.
Fairies don't have that taste.
Despite this, Zhang Chun rested on the tree house for the night.
On April 24, 1940, Wu Hao went to Aldan, met with Emperor Hirohito and Prime Minister Fumima Konoe, and reached a preliminary agreement on agricultural cooperation in the Far East.
At a press conference, Wu Hao reaffirmed China's sovereignty over the southeastern region of the North Mountains, including Kamchatka and Chukotka.

However, there were no specific consultations with Japan on the region, and no objections were raised to the Japan-US mutual defense treaty.
Konoe Fumima, for his part, only emphasized the significance of agricultural cooperation in the Far East.
The United States, which was already very nervous, breathed a sigh of relief.
However, as the Sea of Okhotsk and Bering Sea began to thaw, China's North Sea Fleet and the First Pacific Fleet appeared frequently in these areas.
Apart from the confrontation, there were no major conflicts between the ships at sea, and most of them were the Chinese fleet that took the initiative to retreat.
But submarine warfare and anti-submarine warfare began.
The United States knows that there are not many ships in the Chinese fleet, and the loss of one is one.
It came to mind to defend the Pacific Ocean and the Kuril Islands with submarines.
The Japanese-American combined fleet was actually mainly Japanese ships, which the Americans did not feel distressed to use, and were used to blockade the island chain of the Whale Sea archipelago.
And the US Pacific Fleet performs blockade missions in the Pacific Fleet.
The huge shipbuilding capacity of the United States was displayed at this time, and there were more and more American warships in the Pacific Ocean.
Often, two or three fleets came to confront the Chinese fleet.
Bai Chongxi finally understood what Zhang Chun was worried about.
The United States does not allow powerful countries to come near its own territory, and it is unlikely that it will make any concessions at such a time.
The long battle for the Pacific began.
