What is the longest lived tree? How long do you live?

Who is the oldest plant birthday in the world? According to research, redwoods, baobabs, and Australian eucalyptus trees can live for many years, while the giant sequoia, the "Lord of the World", has lived for many years, but these are not the oldest of the plants. When the famous geographer Humboldt was on an expedition to the island of Orta in Africa, he found a plant that was already up to a year old.

Unfortunately, the tree had been broken by a recent storm. Because its trunk was broken by a storm, Humboldt was able to tell the exact age of the tree by counting the rings where it was broken. This is the longest-lived plant known so far.

This long-lived tree is called the dragon's blood tree, the tree is meters high, the diameter of the main trunk is nearly meters, and the diameter of the broken part is also meters meters from the ground. This long-lived tree is called the dragon's blood tree, the tree is meters high, the diameter of the main trunk is nearly meters, and the diameter of the broken part is also meters meters from the ground. Dracaena is a lily plant, which is found in many species in the world, and is found in the tropical rainforests of southern China.

It grows very slowly, taking hundreds of years to grow into a tree and only blooming for decades, so it is very rare and valuable. When injured, the dragon's blood tree will emit a blood-colored liquid. This liquid is a kind of resin, dark red, is a kind of precious Chinese medicine, the Chinese medicine is called "blood exhaustion" or "unicorn exhaustion", can ** muscle and bone pain.

Ancient people also used the resin of the dragon's blood tree as a raw material for the preservation of corpses, because this resin is a good antiseptic. It is also a raw material for making paints.

Remember.

The world's longest-lived plant - Dracaena: The Dracaena tree is more than 8,000 years old.

The longest lifespan of a tree is more than 8,000 years.

In 1868, geographers found an 8,000-year-old plant, its name is Dracaena, mainly distributed in southern China and tropical Asia, due to slow growth, hundreds of years to become a plant.

The dragon's blood tree is named because the sap that flows out after the injury is red, like blood, and it is also known as the tree of bleeding, it is also a very precious Chinese herbal medicine, known as Yunnan red medicine, and the plant shape is beautiful, the leaves are rich in color, the leaf shape is huge, and the adaptability is very strong.

Dracaena likes a sunny, high temperature and humidity environment, negative resistance is also strong sail limb oak, suitable for indoor cultivation, as long as the temperature conditions are suitable, the plant is in a state of growth all year round, the dormant temperature is 13 degrees Celsius, and the wintering temperature in the early winter hunger season can not be lower than 5 degrees Celsius.

Measures to prolong the senescence of trees

1. Maintenance of damaged root system

In the process of landscaping, many roots are often broken, resulting in a decline in the absorption function of the root system, or a temporary loss of absorption capacity. For root maintenance, we can water it with rooting agents and fungicides to make the root system healthy and expand the root absorption area.

2. Adjustment of soil pH value

In the process of landscaping, due to the uncertainty of the soil, or the pH value of the local soil, it is acidic or alkaline. Cause some garden plants to adapt to the pH of the soil. If the alkalinity is too high, we can add a small amount of aluminum sulfate, ferrous sulfate, sulfur powder, etc. to the soil, and apply an appropriate amount of organic fertilizer.

If the soil is acidic, lime can be added in moderation.

3. Treatment of soil compaction

Soil compaction and impermeability often cause root respiration to be obstructed and absorption function to be reduced. For this purpose, the compacted soil should be loosened or perforated frequently. You can even replace the nutrient soil and lay wood chips or breathable pavement on the surface of the tree cavity to prevent excessive trampling.
