What is the thickest tree DBH? The thickness of the trunk is generally small

A: The diameter of the thickest tree is meters. Details:

In a voluminous botanical work published 100 years ago, the trunk diameters of some well-known tree species were listed. The thickest of them is the chestnut tree, which is 20 meters in diameter. The following are Mexican lupus, meters in diameter; plane wood, diameter meters; Taxus lanceolata, m in diameter; giant sequoia, 11 meters in diameter, baobab, in diameter; broad-leaved linden tree, 9 m in diameter; Eucalyptus, 8 meters in diameter, .......

It can be seen that the trees that grow thick are often some trees that are not too tall, such as the chestnut tree is no more than 30 meters high, the Mexican luch is about 40 meters high, and the baobab tree is only more than 20 meters high. All over the world, the stout trees are mostly some ancient and famous trees that have gone through the green mulberry. For example, the ancient ginkgo tree in Dinglin Temple in Ju County, Shandong Province, China, with high rice and chest circumference, is said to have lived for more than 3,000 years.

There is an ancient camphor tree that is more than 2,000 years old in Guangxi, China, with a height of 30 meters and a diameter at breast height. In Kagoshima Prefecture, Kyushu, Japan, there is one of Japan's largest camphor trees, 30 meters high, with a diameter of meters around the trunk at a distance of meters from the ground. According to the 1985 edition of the Guinness Book of World Records, the three thickest trees in the world are:

A Mexican fallen fir tree in Oaxaca, eastern Mexico, with a height of meters and a dry circumference meter from the ground; A European chestnut tree on the European island of Sicily, measured in 1972 with a trunk circumference of meters; A baobab tree on the African continent with a trunk circumference of more than meters and a diameter of meters. Of these three unusually stout trees, the most famous is the European chestnut tree in Sicily. Growing at the foot of Mount Eitlie, the tree was famous for its huge canopy that sheltered the king and his retinue of more than 100 people during the medieval reign of the Kingdom of Aragone, and is now one of the island's most scenic attractions.

European millet, also known as sweet chestnut, is produced in Eurasia and northern Africa, nuts are edible, wood is excellent, can be used for construction, furniture, joinery. It is native to eastern Mexico, distributed north to southwest Texas, USA, and south to Guatemala. These two trees rarely have a DBH of more than 4 meters in their native areas, so the Mexican larch tree and the European chestnut giant tree of Ganwei rice are both grown over thousands of years in a specific environment, and are one of the most precious botanical heritages in the world.

As for the baobab tree, this book is dedicated to it and will not be repeated here.

The thickest tree, on the side of Mount Etna in Sicily, is a large chestnut tree called the "Hundred Horse Tree", the circumference of the trunk is about 55 meters, and it takes more than 30 people to join hands to surround it. There is a large hole in the lower part of the tree, and the chestnut pickers use it as a dormitory or warehouse. This is indeed the thickest tree in the world.

That's a lot bigger, tens of meters. Lord of the world, there is a hole in the middle of the tree, and a road has been built inside.

The thickness of the trunk is generally about 20 cm, the diameter of the trunk is generally about 30 60 cm for the large old tree, and the diameter of the trunk is about 5 15 cm for the small tree. Methods to make the trunk thicker: sufficient light, during the growth period, should ensure that there is sufficient light treatment every day, as far as possible to scatter light; Water and fertilizer are reasonable, watering should not cause potting soil to accumulate water, fertilization should be combined with watering.

In fact, the thickness of the trunk is generally about 20 cm, for this is not certain, mainly according to different varieties, if it is an older tree, the diameter of the trunk is generally about 30 60 cm, or even a little larger.

The thickness of the trunk of some special varieties can reach about one meter, and the thickness of the trunk is different depending on the variety of trees, while the small trees may only reach about 5 15 cm, so it is best to pay attention to the care when planting.

1. Sufficient light

Most tree trunks like to grow in a sunny environment, during the growth period, should ensure that there is sufficient light treatment every day, as far as possible to scatter light, not in the shade for too long, so as to promote the photosynthesis of leaves.

2. Water and fertilizer are reasonable

During the growth of the plant, watering should be determined according to different varieties, if it is wet, watering should always keep the potting soil moist, but do not accumulate water, if drought tolerance, you can maintain the watering principle of seeing dry and wet, but also to ensure that the fertilizer is sufficient.

According to the 1985 edition of ".

Guinness Book of World Records.

According to the records, the results of the 1972 measurement of this chestnut tree were: the circumference of the trunk in meters; The diameter of the trunk is meters. Among the three thickest trees in the world, the "Hundred Horses Great Chestnut Tree" is in second place, the other two: one in the eastern Mexican state of Oaxaca.

Mexican lupus.

The height of the tree is meters, and the circumference of the trunk is meters from the ground; A baobab tree on the African continent with a trunk circumference of meters.
