The trees that lose their leaves in autumn are: Acacia and Luan.

White wax, ginkgo, tung tree, green tung.

Eucommia, zelkova, oak, persimmon, jujube, red leaf tsubaki, thousand-headed tsubaki, toon, stinky toon, weeping willow, golden willow, fast-growing willow, lupus fir, pond cedar, metasequoia, (wide, red, white) magnolia, black tree, Chinese acacia, weeping locust, black locust, fragrant locust, horse coat wood, poplar, maple poplar, neem.

I can't say too much about this, because there are too many!

Some trees are evergreen all year round, and autumn is no exception, and these trees are called evergreens. And the trees that turn yellow and lose their leaves in autumn are called deciduous trees. In addition to plane trees, maples, and ginkgo trees, deciduous trees also include metasequoia, black tree, locust tree, elm, poplar, willow, sycamore, maple tree, and many other species.

There are about two kinds of trees that we see in our daily life, one is evergreen in all seasons, such as pines and cypresses, these trees do not lose their leaves, but have some fallen leaves in each season, so as to remain evergreen; The other type of tree is what we often call deciduous trees, which tend to have bare leaves in late autumn and bare branches in winter, but they also fall off in other seasons when leaves are eroded by pests and diseases

There are a lot of them. Almost all pine species are evergreen (except for larch), such as cedar, tabuliformis, masson pine, marsh pine, etc.

cypresses; Oriental cypress, thousand bucket cypress, dragon cypress, juniper, etc.

There are also magnolia, ten merits, osmanthus, camphor, smiling, tung, mosquito mother tree, coral tree, large-leaved boxwood, holly, bone, superba, octagonal golden plate, privet, huangxin, oleander, nantian bamboo, etc.

Of course, it is also divided between the south and the north.

Pine, cypress, camphor, privet, boxwood, tung, magnolia, camellia, rhododendron, orange, bone, stepwood, euonymus, rubber tree, podocarpus, ruixiang, araucaria, brazilian iron, cycad, rice seed orchid, osmanthus, laurel.

The leaves on trees have a certain life period, and the length of life varies from plant to plant. Every leaf falls off when it reaches a certain age, and pine and cypress trees are no exception. Its leaves are also to decline, but the leaves of the pine and cypress tree have a long life period, can live for 3 5 years, and when they are replaced, they are alternate with each other, generally after the new leaves occur, the old leaves are then withered, and the whole tree seems to be not deciduous as if it does not fall leaves, so it makes people have the feeling of being evergreen in winter and summer.

There are a lot of them. Trees usually lose their leaves in autumn.

The north is different from the south, not all of the south loses its leaves, and the trees in the north fall in the fall.

Trees that lose their leaves in autumn include plane trees and ginkgo trees.

The desert that swept through your heart is branded four.

There are a lot of deciduous plants in autumn, and there are many common ones;

Magnolia, Bauhinia, Purple Leaf Plum, Wisteria, Sakura, Neem, Acacia, Plane Tree, Paulownia, Hibiscus, Hibiscus, Crape Myrtle, Luan, Tree Tree, Triangle Maple, Acer Chinensis, Green Tree, etc.

In the north, in addition to pine and cypress, poplars, willows, elms, maples, mulberries and other common trees are deciduous and deciduous. Laurel trees, ginkgo trees also lose their leaves, and sycamore trees are beautiful when they fall leaves. Autumn can go photography.

1. Pine: Korean pine, whitebark pine, tabuliformis pine, black pine, masson pine, cedar.

2. Cypress: ground cypress, cypress, pencil cypress, sprinkled golden cypress, cedar, juniper, etc.

3. All kinds of fir trees: cedar, pond fir, spiny fir, araucaria.

4. Others: azalea, tea tree, osmanthus tree, laurel, camphor tree, euonymus, feast this medlar, large-leaved boxwood, small-leaved boxwood, privet, stepwood, state banyan tree, magnolia, etc.

Whether a tree is defoliant or not is determined by its long-term evolutionary evolution and adaptation to the natural environment. Trees that don't drop their leaves in autumn are because the tree produces less exfoliating acid, which is not enough to make the leaves fall.

Pine, cypress, camphor, privet, boxwood, tung, magnolia, camellia, rhododendron, orange, bone, stepwood, euonymus, rubber tree, podocarpus, ruixiang, araucaria, brazilian iron, cycad, rice seed orchid, osmanthus, laurel, etc.

Trees that lose their leaves in autumn are: poplars, willows, elms, acacias, ginkgo trees, ash trees, oak trees, metasequoias, black locusts and many more.

1. Poplar. The trunk of the poplar tree is straight and straight, with longitudinal lobes on the surface, grayish-white in color, and apical buds. Its leaves are alternate and have oval-lanceolate shapes, triangular ovate, oval, etc.

The leaves are green in spring and summer, and when the temperature drops in autumn, the leaves slowly turn yellow and fall off. By the end of autumn, almost all of them had fallen, and the entire tree was bare.

2. Willow tree. The leaf shape of the willow tree is lanceolate and sparsely grown. The color of the leaves during the growing season is emerald green.

However, after the autumn cooling, the leaves will slowly fall, and the holes will fall out early, especially in the cold areas of the north. In winter, when the temperature is low, leaf loss can reduce water and nutrient consumption, which can promote better wintering.

3. Elm. The leaves of the elm tree also fall in autumn and are bare in winter. It is also very adaptable and can basically survive the winter safely.

During the growth period, the temperature, soil, and humidity requirements are not high, and if you can take care of it, it will grow vigorously.

4. Acacia tree.

Acacia trees are deciduous trees that bloom in summer, between June and July. When flowering, the flower color is pink, and when combined with green leaves, the ornamental value is high.

5. Ginkgo biloba.

The ginkgo tree also loses its leaves in autumn, but its leaves first turn golden yellow in autumn and then slowly fall off. When the leaves turn yellow, the ornamental value is high.

Autumn deciduous trees have acacia, luan, white wax, ginkgo, tung tree, etc., acacia is also known as lantana, it is a deciduous tree, the flowering period is in June to July every year, after flowering is light red, Luan tree is a deciduous tree or shrub, its bark is very thick, the color is brown or gray-black.

1. Acacia

Autumn deciduous trees have acacias. If you want to grow acacia, you need to select a loose and breathable soil rich in organic matter, then use high temperature to disinfect and sterilize the soil, and finally plant the plants in the soil.

2. Luan tree

Trees that fall deciduous in autumn have luan, as it is a deciduous tree or shrub. When cultivating Luan trees, you can water the plants every 5-7 days to provide sufficient water for the Luan trees and promote the growth of the plants.

3. White ash

Trees that fall deciduous in autumn have ash. When cultivating ash, you can use scissors to prune it, first sterilize the scissors when pruning, and then cut off the branches and leaves of the plant that do not grow well, and then cut off the leaves with dense ash growth to increase the light transmittance of the plant.

1. Non-deciduous trees include: cypress, fir, palm, etc. Causes of tree defoliation:

Autumn is followed by winter, and the temperature begins to drop. At this time, the temperature is low, the air is dry, and the groundwater is not easily absorbed by the roots. Because trees rely on leaves to synthesize and evaporate water, at this time, trees cannot absorb water and cannot supply the respiration of leaves.

2. Trees need to be dormant for self-protection, and the overwintering dormant trees themselves also need nutrients, in order to regulate their own homeostasis, many trees need to reduce the loss of water and nutrients through leaf loss and save energy, and wait until the conditions are suitable before sprouting from the new. Repentance.

3. There are many trees with low water loss, such as pines and cypresses with leaves like pinpoints, which can maintain their own water and nutrient balance without falling leaves, so they can remain evergreen.
