What kind of plants are resistant to fire? What are the heat tolerant plants?

Plants that have a certain resistance to fire, and green plants have more water in their bodies during the growing season, and they all have a certain degree of fire resistance.

Non-flammable plants, the leaves are mostly fleshy or filmy, the body contains less cellulose, it is easy to rot after drying, the plants are short, not easy to dry, often grow in fertile and moist places, and mostly belong to the ranunculaceae, sorrel and saxifrage plants.

Most of the early spring plants in the Northeast forest area belong to fire-resistant plants, and they have flowered and grown leaves in the spring fire prevention period, such as Binglihua, Caoyumei, Wufuhua, Yanhusuo, etc. There are also plants that can stop the spread of fire, such as stone pine, tamarix, etc.

Fireproof trees generally have the characteristics of evergreen leaves, thick epidermis, less wax, rich in water, etc., and generally have the characteristics of non-combustible trees with these characteristics often have a certain effect of preventing fire from spreading, such as the ginkgo biloba branches and leaves in deciduous trees are rich in water and are not easy to burn; The cortex layer of quercus and cork oak is thicker, and it also has a certain fire prevention effect. [3]

The main reason why trees can be fireproof trees is that these trees have a particularly strong water metabolism function, which can effectively block the conduction of heat radiation.

In the case of the need for fire barriers, the selection of these trees can be fully considered.

The heat tolerance and insulation properties of trees often vary depending on the species, tree shape, bark and leaf density. For example, coral trees with a more uniform tree shape can block 83% to 93% of the radiant heat; A single olive tree can block 36% of heat, and three trees planted side by side can block more than 90% of heat. For example, if the tree shape and leaf density are relatively consistent, planting one tree can block 90% of the radiant heat from passing, and three plants planted in parallel can block more than 95% of the radiant heat from passing, and its thermal insulation effect is comparable to that of a fire insulation wall.

Due to the different heat resistance and insulation properties of various trees, people call tree species with strong heat resistance and heat insulation performance "fireproof trees".

At present, the evergreen broad-leaved tree species with strong heat resistance and thermal insulation performance are known to include T. chinensis, holly, privet, bayberry, nanmu, coral tree, Camellia oleifera, Kemu and so on. Among them, Camellia oleifera, bayberry, Kemu and other fireproof tree species have become the tree species in the green fireproof forest belt of Masson pine forest area in southern China.

Zinnia is "zinnia", it is an annual ornamental flower, generally sown and cultivated after the spring is warm, and can continue to bloom in spring, summer and autumn, if the winter temperature is relatively high, it can also continue to bloom, suitable for arranging a combination of potted plants.

Sea pine is also a tree that is not afraid of fire. Sea pine is a kind of tree that grows in Hainan, China, and the pipe made from it will not be burned even if it is smoked and burned for many years. This is due to the special heat dissipation capacity of sea pine, the wood is hard and particularly resistant to high temperatures.

In Angola, Africa, there is a peculiar tree ——— Zi Ke. Between its branches, there are steamed bun-like knotted buds, which are filled with liquid, and the knotted buds are covered with small holes. As soon as they encounter a flickering fire, they immediately eject a liquid from the hole, which contains carbon tetrachloride, which is very capable of extinguishing fires.

For this reason, people call this tree "fire extinguishing tree".

It is not surprising that plants that are not afraid of fire are not afraid of fire, but these species have gradually developed a self-protection ability in the long process of evolution.

1. Iron tree. The higher the temperature of these plants, the more waves they grow, and the iron tree is a traditional excellent ornamental plant in our country. Also known as cycads, anchovy banana.

Rich in tropical botanical flavors. The iron tree is a very sun-loving species, and the more sunlight it has, the stronger it will grow. Avoid moisture, drought tolerance, cold tolerance.

It likes light but is not resistant to exposure to the sun and warm, and can be placed in direct sunlight.

2. Sunflower.

The higher the temperature of these plants, the more waves they grow, and there is also a name at home called "can't die", which means that its vitality is very tenacious and not easy to die. Sunflowers prefer warm, sunny and dry environments to see the sun bloom. Native to Brazil in South America.

It is now cultivated all over China. There are many colors, light fragrance, easy to raise and easy to survive.

3. Verbena.

The hotter these plants are, the more waves they grow, verbena, perennial erect herbaceous plants. Most of them grow in the wilderness; It is native to Europe and is distributed in most parts of Eastern, Southern and Southwest China. Prefers dry, sunny environments.

The requirements for the soil are not strict. Likes fertilizer, likes moisture, is afraid of waterlogging, is not tolerant to drought, and can grow in general soil. It's the least picky plant.

4. Hibiscus.

The warmer these plants are, the more waves they grow, and the hibiscus is a perennial semi-shrub of the Malvaceae family. The flowering period is in summer, and the flower buds are very numerous, the petals are light, and the flower shape is delicate. Light-loving, not cold-tolerant, fat-loving.

Origin: Shandong, Anhui, Jiangsu Changjing Garden, Zhejiang and other places. High ornamental value.

The higher the temperature of these plants, the more waves they growConservation method: Hibiscus loves light, and it is best to maintain more than 6 hours of light per day. Sufficient light can promote more robust plant growth, and too much shade is prone to longer internodes and less flowering.

Keep it indoors in a sunny place. In summer, fertilizers with high phosphorus content are applied once every 10 days or so. Watering should keep the potting soil moist.

5. Blue snowflakes.

The higher the temperature of these plants, the more waves they grow, the blue snowflakes are also called mountain ash firewood, horn pillar flowers, perennial erect herbs, strong growth, heat resistance, high temperature and high humidity resistance, less pests and diseases, simple management, long ornamental period. Especially suitable for summer raising, blue snowflakes are resistant to high temperatures but should not be exposed to the scorching sun, requiring a humid environment, and dryness is not conducive to its growth.

Plants that can survive in the tropics should be relatively resistant to high temperatures.

For example, cactus, banana, rubber, lychee, longan, dragon fruit, etc.

What kind of high temperature is resistant, live plants, dead plants or seeds, and the harder the dead plants, the more resistant they are to high temperatures; Living plants can be found in the desert (various half-dead states), eucalyptus, with thick bark, which cannot be burned by fires in the forest, and grows better; Seeds, there are plants that can secrete a kind of oil, the natural temperature is more than 40 degrees Celsius spontaneous combustion, burning the surrounding plants and itself to provide nutrients for its seeds, its seeds are fire-resistant, and germinate after a few days.

Cactus desert it can endure.

1. Fragrant sparrows.

This small floret native to the tropics is very heat and drought tolerant.

Italian jasmine is the most heat-resistant and drought-resistant, and my balcony sunroom has a high temperature of nearly 50, and I don't water it for half a month, but I still live well.

Jasmine, vandailan, cactus, morning glory, mint, stepweed, honeysuckle, privet.

Succulents, such as cacti!
