The towering trees in the sky walk into the endless tropical rain forest in Xishuangbanna, and newcomers will be surprised at its height. No way, maybe you will ask, what is the tallest tree in this rainforest? I can tell you that among thousands of trees in the tropical rain forest of Xishuangbanna, the tallest one is Wangtianshu. Its height is more than 80 meters, and it can generally grow to 50-60 meters, which is 20-30 meters higher than other trees. Although Wangtianshu is half shorter than Australia 150-meter-high apricot tree, the world's largest tree, and half shorter than America 142-meter-high redwood tree, it stands out in the tropical rain forest and is surprisingly high. Cephalotaxus grandis can be regarded as the highest rainforest community and the highest tree species among the existing tropical rainforest vegetation in China and even in Asia. If it is only the height of the tree, it is certainly not so precious, and it is certainly not expected to be listed as a national first-class protected plant. It is also valuable because it is a Dipterocarpaceae plant and a dominant family in the tropical rain forest. In Southeast Asia, this family is one of the representative tree species of tropical rain forest, and it is also one of the important symbols of tropical rain forest. In the past, some foreign scholars asserted that "there is a great shortage of Dipterocarpaceae plants in China" and "there is no tropical rain forest in China". However, the discovery of the tree not only completely overturns these conclusions, but also confirms the existence of a tropical rain forest in China. The tree of Wangtianshu is very tall, its trunk is completely straight, its crown is like a huge umbrella, and its trunk is like an umbrella handle. So the Dai people in Xishuangbanna call it "buried trunk" (umbrella-handle tree). Like other trees in Dipterocarpaceae, Cephalotaxus japonicus is famous in the world timber market for its excellent materials and wood accumulation rate per plant. According to the data, the trunk wood of a 60-meter-long Salicornia bigelovii Torr can reach more than 10 cubic meter. Its material is heavy, the structure is uniform, the texture is flat and not easy to deform, and the processability is good. It is suitable for timber industry, mechanical processing and large-scale timber use, and is an excellent industrial timber tree species. Plate root refers to a plate root, which is not cylindrical, but develops into a vertical flat plate and is exposed on the ground. Giant trees growing in tropical wetland forests, such as banyan and red thick shell, are common tabular root plants. Plate root can be regarded as a kind of aerial root. In the strangulation of animals and plants, it is natural for animals to eat the jungle. However, plants don't have as much activity space as animals, and their growth range is narrow and they can't move, but there is also a jungle phenomenon between them. Strangled plants in the tropical rain forest are the winners of competition among plants. Tropical forest area is very suitable for the growth of tropical plants because of its high temperature and humidity. There are many kinds of plants in the plant community, and the interspecific density is very high, so the living space of each plant is reduced, and the opportunity to receive sunlight is correspondingly reduced. In order to survive, there is fierce competition between plants for sunlight and soil nutrients. In natural competition, those plant species with growth advantages can get enough sunshine and nutrients to survive in the competition; Those plants that are at a disadvantage will eventually be eliminated. Scientists found that in the tropical forests of Panama, many small trees and vines around some big trees died one after another. After observation, it was found that there was a huge root swelling at the root of the big tree, which grew and expanded rapidly in the soil, forming extrusion pressure, destroying the roots of neighboring plants, and even squeezing their own roots out of the ground, making other plants have no place to stand and die pitifully. Strangulation can also be seen in Dinghushan, Guangdong and Jianfengling forest areas of Hainan Island. For example, the seeds of Ficus tenuifolia are eaten by birds and excreted with feces. When they fall on the trunk or branches of Korean pine, the seeds will sprout and take root, and the seedlings will grow into dense shrubs. After that, many geotropic aerial roots were born. Some aerial roots are attached to the trunk of the host, while others hang down from the branches of the host, and the descending roots gradually increase and merge with each other until the trunk of the host is completely wrapped by its powerful wooden root network. At this time, the crown of Ficus tenuifolia also grew luxuriantly, which covered the crown of the host. Because of the lack of sunlight, its own nutrients were sucked dry and eventually strangled, which made it look decadent. The root net of the slender banyan tree is an empty pipe, but it can still live a completely independent life. Strangled plants like banyan usually end up as tall trees in the upper forest of tropical rain forest. There are many kinds of strangled plants, such as Ficus of Moraceae, Eupatorium of Araliaceae, Hedyotis of Lacqueraceae, etc., but they mainly live in tropical rain forests, and the species and individuals of strangled plants in subtropical forests and temperate forests are far less than those in tropical rain forests. Species of Asian Elephants: Mammals: Hornnose: Elephant Elephant belongs to Elephant Elephant, Elephant Elephant Family, and it is the largest land animal in the world. It lives in the tropics and often roams in valleys, rivers, bamboo forests and broad-leaved mixed forests below the altitude of 1000 meters, living in groups, with several or dozens of heads in each group, with an adult male elephant as the head. Elephants are very clever, easy to domesticate and have a good memory. In the wild, elephants have self-defense and revenge for the provocation that destroys the living environment, hurts their companions and offends their dignity. The age of sexual maturity of elephants is about 12 years old, the gestation period is 600-640 days, each fetus gives birth to 1 offspring, and the life span is 50-60 years old. Elephants usually move in the morning and at night. If the bright moon is in the sky at night, they will also come out to feed. Elephants tend to move unstoppable, with poor eyesight, but good sense of smell and hearing. There are few wild Asian elephants now, and they have been tamed in some countries in Southeast Asia? An ant frog that has been raised for n nights? Right? Planting and adding plants is quite fresh. Thirst? ∩伲 Next to meteorite protection? Apple stool? What is it now? The Green Peacock River is richer in food, and the English name Pavo muticus, alias Java Peacock, is distributed in southern Yunnan, with males about 140 cm and females about 100 cm. The male bird's feathers are blue-green, and its back is shiny with copper. There is a cluster of upright feather crowns on the top of the head. The tail is covered with feathers and extends into a tail screen, which can reach more than 1 meter. There are many big eye spots on the feathers, which are extremely gorgeous and dazzling when the screen is turned on. The female bird's feathers are mainly brown with a green glow. No tail screen. Living in valleys below 2000 meters above sea level, as well as open areas near sparse forests, bamboo forests and shrubs, one male and many females are often seen. Mainly eat mushrooms, berries, grain seeds, grass seeds and so on. And eat insects, frogs, lizards, etc. In late February, the breeding season began, and most of the nests were built in the depression between the ridges and shrubs on the shady slope. Each nest lays 4-8 eggs, usually 5-6 eggs, and the eggs are milky white, brown or milky yellow. Female birds hatch eggs for 27-30 days. Peacock's beautiful feathers have always been people's favorite decorations. In the Qing dynasty, the "flower feathers" made of them and the tail feathers of brown-eared pheasants were used to distinguish official ranks according to the number of feather eyes. Peacock moves like dancing. People imitate their movements and weave "peacock dance", which is vigorous and beautiful and intoxicating.
