Does the discovery of a large scale living fossil alder group in Changning indicate that the local

In a surprising piece of good news in the hot spring town of Changning County, a large group of living fossils was found in the mountain forest. Through the preliminary survey of forestry professionals, it was found that there were more than 200 large and small alder communities, consisting of 4 relatively independent small communities. Belonging to the same reptile age as the dinosaurs, it is the only woody fern in existence, and has been called by the scientific community as a "living fossil" for studying paleontology and the evolution of the earth.

These alders are mostly mixed with other ferns and are found in broad-leaved forests. They have trunk thickness, crown size, and age of old, adult, and young trees, with a small number of trunks and stumps after natural death, and the entire alder community grows naturally.

The largest alder tree is more than 14 meters high, with a DBH of 41 cm and a root diameter of 60 cm. It's a huge umbrella spectacular. Alder is a representative of ferns among the remnant plants.

Ferns are a lower class of higher plants in the kingdom Planta. In ancient times, ferns were originally tall trees. Due to various disasters, most of them were buried deep underground and turned into coal.

Most of the plants on Earth today are dwarf herbaceous plants, and only a few woody plants have survived. So far, fructose is like that. Alder is known by the scientific community as a living fossil that studies paleontology and the evolution of the earth.

Alder is an amazing plant. It is the only fern with lignified stems. If you want to transplant, the temperature should not be too high.

It can be transplanted in combination with the current temperature. Dredge, the size of the mud mass is 8-10 times the diameter of the stem. Alders are even more precious.

After alder is used in medicine, it is made into dark brown dry tablets, which are called keel wind. Due to its quality and origin, it will also vary. However, the dried herbs in the market are generally 35 to 50 yuan per kilogram in ** or Chinese medicine pharmacies**.

There are dense traces of adventitious root fractures and large petioles on the surface of the keel wind, and there are depressions underneath. It tastes a bit bitter.

Yes, it shows that the local ecological environment is very good, so there are a lot of living fossils, the historical research value is also very high, and the environment is protected very well.

Yes, it proves that the local environment is very good, so it will survive in these places, and it proves that the pollution is not particularly serious.

Yes, it shows that Changning once had a very advantageous environment, which was suitable for the growth of the "living fossil" alder group.

Baoshan Changning found a large-scale "living fossil" alder group, this plant lived in the same era as the dinosaurs, 2-300 million years ago. Alder is a fern, and unlike the usual dwarf ferns, this plant can grow into a "towering tree", with a maximum record of 14 meters, with an average height of 5-6 meters.

Just such a shape is enough to break our understanding of ferns. The impression of ferns is that they are dwarf plants that grow in moist, warm, and shady places. It's the first time I've heard of a large fern like alder, so it's no wonder that it was able to grow in the age of dinosaurs as one of the recipes for herbivorous dinosaurs.

The environment suitable for the growth of Alder spinula is warm, humid, and there is no pollution, and its own light requirements are not high, and only a short period of light can meet the growth needs. Such an environmental requirement can make the alder grow to a height of about 6 meters, and with the unique leaf characteristics of ferns, the alder looks like a giant umbrella from a distance.

This time, there are more than 200 alder groups found in Changning, Baoshan. According to the locals, these alders have been around for a long time, and although the locals do not know its name and value, they still protect it because of its rarity and rare shape.

Alder is a fern that can grow into a large tree, hence the name "tree fern". The huge canopy allows the tree to grow to a diameter of about 60 cm. People who don't know anything about plants have a hard time associating them with ferns after seeing them.

This tall fern seems to be very strong, but in fact it is "strong on the outside and dry in the middle". The stem of the alder stands straight, but the inside is hollow, and when viewed from top to bottom, it is the same as if we were using a pen holder.

The fact that alders can grow and reproduce here in Changning also shows that the climate and environment here are suitable for their survival. This plant is as precious as a national treasure.

Overgrown with plants, it is an independent plant with research significance, distributed in the dense forests on the hillside, and you can learn a lot about it.

The height of this plant is very high, most of it grows mixed with other ferns, the trunk is thick and thin, the vitality is very tenacious, and the growth rate is also very fast.

The appearance of this plant is very tall, the arrangement of leaves is very orderly, there are many roots on the tree, and each leaf has a lot of branches, which is the appearance of the plant.

The characteristics of the appearance of the plant are as follows, the trunk is thick and thin, the crown is large, the age of the tree is small, there are old trees, adult trees, young trees, and a small number of natural dead trunks, stumps, these trees are 5 6 meters high on average, shaped like a giant umbrella, particularly spectacular.
