After arranging this, Han Zifeng teleported again to the side of the light-leaved fern. She took some photos of this small plant again, and Xiaoqi added that the light-leaved fern is an evergreen plant in the shade of the forest, belonging to the family Pteridaceae and the genus Light-leaved Fern. It is a national first-class key protected wild plant and an endangered species in China. It has only been found in Tianquan, Erlang Mountain and Tuanniuping areas in western Sichuan, my country, and grows in the shade and wet places under the forest at an altitude of 1 meters.

The appearance of the light-leaved fern is very special: it usually has only one leaf, which is very thin and about 40 cm long. It is densely covered with more than 10 pairs of symmetrical pinnae, and the widest part of the pinnae is only 8 cm. The place where its seeds are stored, the sporangium, grows on the pinnae. It can be said that one leaf is almost the whole of a light-leaved fern. The annual average temperature is 6-8°C, the extreme maximum temperature is 28°C, and the extreme minimum temperature is -16°C; the annual rainfall is 1800-2000 mm; the relative humidity is 85-90%; there are more than 280 foggy days throughout the year; the number of sunshine hours is less than 1000 hours. The soil is mountain yellow soil and mountain yellow-brown soil developed with limestone, sandstone and shale, with a pH value of 4.5-5.5. The light-leaved fern grows under the shady slope forest. The main vegetation type is subtropical mountain evergreen and deciduous broad-leaved mixed forest. Leaves sprout in late spring and sporangium forms in July and August. Mature in September.

Seeing that there was nothing going on here, she simply sent down some spiritual rain again to ensure that the light-leaved ferns here could grow better. After being satisfied, she teleported to the side of the Yunnan tung again, and then frowned, always feeling that there was something wrong with the plants here.

The old way, he said to his live broadcast room: "Lao Feng, call someone, this tree is not right, it needs treatment."

What could Feng Hu say? Just make the arrangements. But he was also curious and asked, "Girl, what's wrong with the tree?"

Zi Feng was silent. He looked at the trees with his mind and said, "I don't know. How should I put it? It feels like there is nothing wrong, but it seems like there is a big problem. The whole tree looks healthy, but I feel like these trees are getting unhealthy. Let a professional check if there is something wrong with the soil nearby. Apart from the soil pollution, there shouldn't be anything wrong with the trees, right?"

A group of professionals came very quickly, and according to Zi Feng's instructions, they took samples from the soil, tree roots, etc. for testing. Since many people were waiting to hear the results, the testing was very fast. As a result, it turned out that there was indeed a problem with the soil, and the tree roots were infected.

Zi Feng asked: "What should we do about this?"

The people here said, "It's a minor problem. Fortunately, it was discovered early. It will be fine after a few days if it is neutralized." She nodded, but still tried the spiritual liquid. Hmm, it really did have a detoxifying effect. After a small area of ​​rainfall nearby, she said, "You guys should keep an eye on it. I always feel like something is wrong with this."

What can the forest ranger here say? Just make the arrangements. After all, they also think that it is still acceptable if there is a problem with your soil suddenly. Zi Feng is speechless. This group of guys happily set up a camera and monitor it. Don't say, they actually saw who did it.

They looked at Zi Feng who suddenly appeared. A group of forest rangers looked at Zi Feng in surprise. They just saw that the person who poisoned was actually in their team. Zi Feng didn't say much. He just killed him with a knife and dragged him away. Everyone shook their heads.

After making sure that there was nothing wrong here, Zi Feng finished filming here and prepared for the next place. The forest rangers here also began to monitor this place carefully. The unlucky ranger, Zi Feng, was taken away first.

As for the introduction, it is still Xiaoqi's code: Yunnan tung, Tiliaceae, deciduous tree, is a national second-level protected plant and one of the endangered plants that the state has identified as key protected and rescued. There are less than 10 rare plants in China, and only 6 are left. It is endemic to southwest China and is also one of the main tree species of the Yunnan tung genus, which is an oligospecies genus. It has important value in the study of flora and geography and the application of breeding precious tree species.

Deciduous tree, 6-20 meters high; young branches are glabrous, and the terminal buds have grayish white hairs. The leaves are papery, elliptical, 10-20 cm long, 5-11 cm wide, with a sharp and short apex, a rounded base, dark green after drying, not shiny, and glabrous above, the same color below, bald, with 3 basal veins, 8-10 mm from the edge of the two sides, no more than halfway up, 5-7 pairs of lateral veins on the midrib, and small teeth on the edge; petiole 1.5-5 cm long. Cymes are axillary, about 3 cm long, with 2-5 flowers; pedicels have nodes; sepals are 5, oblong, about 1 cm long, and hairy on the outside; petals are absent; the outer whorl of stamens is degenerate, with 10 pieces, and the inner whorl of fertile stamens is 20, which are shorter than the sepals; the ovary is glabrous, with 5 chambers, each with 6 ovules, and 5 styles. The winged capsule is oval, 3.5 cm long, 2.5-3 cm wide, with thin wings, membranous, and 5 ribs; the seeds are about 1 cm long. The flowering period is July and the fruiting period is October-November.

Teleporting again to the next place, this is the Chinese parasol tree. Don't mention it, this wood is still very healthy, at least it looks and feels very healthy. Zi Feng commented: Well, this tree is well protected, it is really very healthy.

The shooting is completed, and all that’s left is for Xiaoqi to type. Parashorea chinensis, also known as the satin mung bean tree, is known as the "giant panda of the plant world". It is an evergreen large tree of the genus Thick-walled Caragana in the family Magnoliaceae. It is a national first-class protected plant and is listed as critically endangered.

The twigs of Parashorea chinensis are dark green, 5 to 9 mm in diameter, dark brown in old branches, leathery leaves, narrowly obovate or narrowly obovate-elliptical, solitary flowers at the top of branches, buds green, obovate or ovoid, aggregate fruits green when ripe, dark brown when dry, obovate, elliptical-oval or obovate. It is produced in Yunnan, growing in evergreen broad-leaved forests in mountain valleys at an altitude of 1300 to 1500 meters, mixed with large-leafed Manglietia, Lantern Tree, Bole Tree, etc. The flowering period is April, and the fruiting period is September to November. It has high academic value and is also an ornamental tree species in gardens.

Looking at my list, hmm, the next one should be the Coleus chinensis. Looking at this tree, I am really speechless. It’s not for anything else, the point is that this tree and this position are almost dead, and the whole tree looks a little wilted.

Feng Hu was very perceptive. He quickly called the local forest ranger and asked, "Girl, is there something wrong with this tree?"

Zi Feng was silent for a while and then said, "Well, this tree needs to be moved to another place. If we don't take care of it, it won't survive until tomorrow."

Feng Hu: "Is there a problem with the nearby land?"

Zi Feng shook his head and said, "Strictly speaking, it's the temperature. The temperature here is too high. The trees are about to be exposed to the sun. They are not suitable for such hot places. Global warming is happening now. This is not easy to deal with, unless we build a sunshade and cool down physically, but this requires time to maintain."
