Why do trees look like autumn in spring?

Maybe it's 2 in the possible. 1. The tree species is like that, and the flowers that bloom are that color. 2 It may be that the temperature is low there, and some flowers think it is late autumn, and the color comes according to autumn.

Why there are also fallen leaves in spring, just like autumn.

Why do there are fallen leaves in spring, isn't spring the time when all trees are in spring, it won't be the old and new, and the autumn leaves are not as strong as spring.

I'll answer. 7 articles.

Learning points are always right. From the healthy life sesame group recommended on 2016-05-17Spring flowers, the recovery of all things in spring, is because after a winter of accumulation, recuperation, a spring, the sun is warm, the spring breeze is blowing, the air is moist, these conditions promote the germination of all things. The flowers bloom naturally.

But nature is also very magical, in order to let you have a view all year round, there are flowers to enjoy, there are flowers to bloom all year round. It's just that different plants have different living habits. It is also the result of the adaptation of plants to their environment over a long period of evolution.

The young leaves of the trees grow slowly, and after a period of time, the green leaves slowly turn yellow, senesc, and finally fall off. This defoliation is a natural phenomenon of aging. It is like all living things, and at some point it grows and dies.

Another type of leaf drop is autumn leaves. This defoliation is caused by changes in natural conditions. In fact, due to the shorter daylight hours in autumn, there is more ethylene and abscisic acid in the leaves.

Ethylene and abscisic acid have the effect of promoting leaf shedding, and the base of the petiole forms a delamination zone, and the connection between cells becomes loose under the action of enzymes, and the leaves fall off from the delamination zone when the wind blows. The shedding of flowers and fruits is very similar to the shedding of leaves. Before the decay of flowers, more ethylene and abscisic acid are formed, which causes the fruit stalk to form a delamination zone, causing the fruit to fall off.

Many of the flowers slowly fell asleep, leaving only chrysanthemums and osmanthus flowers quietly blooming. The green grass turned yellow like gold, and the grass withered slowly, like the flowers.

Autumn is one of the four seasons of "Spring, Summer, Autumn and Winter". In China, the "beginning of autumn" of the 24 solar terms is traditionally used as the starting point of autumn. Autumn means that rainfall, humidity, etc. tend to drop or decrease, and everything in nature begins to grow from lush to mature.

According to the modern scholar Zhang Baokun's average temperature, the average temperature is divided into four seasons, and the index is that the period when the average temperature is lower than 10 is winter, the period higher than 22 is summer, and the period of 10 22 is spring and autumn.

Autumn is the best time to maintain health, and it is advisable to eat vegetables. Vegetables not only maintain health, but also assist in some diseases. So, among the seasonal vegetables, which ones are suitable for health?

Autumn is dry, so eat more green leafy vegetables, because the vitamin content is high, and eating more is beneficial.

Dark vegetables such as spinach, greens, celery, chrysanthemum, amaranth, and carrots, like brown-red vegetables, are not only rich in vitamins, but also higher in carotene.

Autumn trees include sycamore, ginkgo, catalpa, ** tree, metasequoia, pond shirt, golden pine, plane tree, poplar, willow, paulownia tree, acacia, cedar, five-needle pine, whitebark pine, podocarpus, tung tree, coral tree, camphor, boxwood, etc.

Autumn trees are characteristic: one changes color, the other falls.

When the plant breaks down the chlorophyll, the green color disappears from the leaves. What is left behind are other chemicals that you don't normally see. The most important of these are carotenoids, which are the reason why carrots turn orange.

Depending on the chemicals in the leaves, they can turn into different hues of yellow or orange or even red. There are no nutrients in these chemicals, so plants don't break them down but leave them in the leaves.

Falling leaves in autumn is a self-protection mechanism for plants. Cold winter is coming, and evergreen leaves have thicker wax and resin on them to protect them from freezing and cracking, but deciduous trees with thinner leaves are not very resistant to cold climates. Because water swells when frozen, leaf cells that contain water are prone to cracking during the winter months, causing them to be unable to photosynthesize.

Late autumn has arrived, and when I walk into the empty campus, a cold wind blows, making people feel a chill.

In autumn, the campus is still glorious and pleasant, and the trees are still so green; The flower doesn't seem to know that late autumn has come, but it still blooms fragrantly, and still attracts bees with its fragrance; The butterfly is still dancing on campus, still attracting the attention of students with its beautiful figure.

A few yellow leaves fell from the trees in the flower beds of the campus, and the air in which people breathed condensed into milky white heat.

Although it is late autumn, the sun still works every day, giving the plants enough light and heat to allow them to grow well in the cold late autumn.

The trees on campus sway in the wind from time to time; sometimes standing still; From time to time, a few poor leaves fell from the branches. However, these do not affect the charm of the greenery in late autumn. The flowers on campus are still blooming, and the bees are still busy collecting honey, and there are many bees flying around the flowers, looking for which one is better.

The sky in late autumn is unusually solemn and hearty, after self-study, the sky is dark, which makes people feel very mysterious, and there are a few stars in the high sky to embellish, making people guess: other stars have gone to **?

I love late autumn, this crisp sky, and this season with a hint of coolness!

Autumn is coming, and the campus flowers and trees have green leaves.

1. The annual herb slowly withers.

2. The leaves of deciduous trees are dry and falling.

3. The seeds of many flowers and trees have matured.

Autumn is here, autumn is here, the flowers and trees on the campus are in full bloom, a breeze blows, exudes a faint fragrance, attracting many butterflies to dance on the flowers; In autumn, the small flowers have withered and withered, leaving only chrysanthemums and osmanthus flowers to bloom quietly.

Autumn leaves of the woods, like pretty butterflies; Autumn leaves of the woods, like lovely fairies; The leaves of the autumn woods, like a sea of gold.

The rhetorical device of metaphor is used.

1. Borrowing metaphor: replacing the ontology with the metaphor, the ontology and the metaphor do not appear, and directly say A (ontology) as B (metaphor).

Example: I seem to have a chill; I knew that there was a patheticly thick barrier between us, and I couldn't speak.

2. Metaphor: also known as "metaphor", it is the ontology and the metaphor that appear at the same time, saying that A (ontology) is (metaphor) B (metaphor). Metaphors are often used by words that are, is, become, become, become, and become.

On our side there are poplars, purple-leaved plums, papayas, elms, peach trees, pomegranate trees, and ginkgo trees, and the fallen leaves are spread on the ground like sponges, and they are soft when stepped on.

In the autumn woods, there are maple leaves, and the leaves of the maple trees are as cute as a small slap and as red as lanterns. In autumn, the woods have pine leaves, as thin as needles.

When we think of autumn, we can think of maple leaves, which are the most beautiful in autumn. So we can compare the maple leaf to a small slap. In addition, the pine trees that remain green all the time in autumn are pine trees, and the pine needles of the pine trees are like a needle.

I felt that there were maple leaves in the autumn woods, and he was like a fiery red sun looking at us.
