Leaves and leaves, fallen wood and fallen leaves mean 40

That is, I went to ask the Chinese teacher myself hahahahaha.

1.The images of leaves, "trees" and "leaves" are not only not mutually exclusive, but also very consistent, giving people the feeling of lush foliage and thick shade; And the "wood leaves" naturally have the yellowish and dry feeling of fallen leaves, which brings the whole sparse autumn.

2."Wood" has two artistic characteristics in the image:

3."Wood" is more simple than "tree", it seems to contain a deciduous factor in itself;

4."Wood" not only reminds us of the trunk of a tree, but also brings the color that "wood" suggests, which may be translucent yellow and touchable.

1. The reason for the fall of leaves of the trees.

When autumn quietly comes, the air becomes drier, and the water in the leaves evaporates through the many voids on the leaf surface, and at the same time, as the weather gets colder, the role of the roots of the tree decreases, and the water absorbed from the ground decreases, making the water supply in short supply. If this continues, the tree will die quickly, and in order to continue to survive, the petioles and branches are connected to form a detachment (even note what is called a detachment - the petioles are originally stiff and stiff on the branches). In autumn, as the temperature drops, several layers of fragile parenchyma cells form at the base of the petioles.

Because these cells are easily separated from each other, they are called delamination. When the separation layer is formed, it breaks if it is blown by a slight breeze, and the leaves fall down.

), the water is no longer transported to the leaves. When the leaves fall off, the bare branches are left, and the tree's water consumption is reduced, so the tree can survive the winter safely, so the tree is also beneficial to lose its leaves.

2. Trees don't all lose their leaves in autumn.

Do trees lose their leaves in autumn? No, trees like pines and cypresses are often described as "evergreen", as if the leaves are not yellow and do not wither, but when we walk into the pines and cypresses, we will also find that there are always layers of fallen leaves on the ground. Pines and cypresses belong to evergreen plants, their leaf life is much longer than the leaves of the fallen leaves, the needles of the pine tree can live for 3-5 years, and they are not like deciduous plants in the old leaves fall off after the new leaves grow, but after the new leaves are born, the old leaves fall off one after another, so the trees maintain the appearance of perennial green, never become bare.

3. Characteristics of tree leaf fall in autumn.

In autumn, the leaves that hang on the treetops are the last to fall. This is because in the process of growth, trees always strive to develop into larger spaces, so they always send a large amount of nutrients to the branches so that the branches can grow outward faster. The treetops grow upwards section by section under the nutrition of the tree, and in the process of growing upward, new leaves continue to grow, and these new trees take on the task of making "rations".

The treetops have always enjoyed the treatment of nutrition, and when the tree no longer provides nutrients and the rest of the leaves are almost lost, the treetops can still rely on the previous "savings" to keep the chlorophyll from being destroyed in the short term. The leaves on such branches are the last leaves to fall on the tree.

The real reason why deciduous trees change color in autumn.

The difference between "fallen wood" and "fallen leaves" is:

"Fallen leaves" are dense leaves that contain water at the turn of spring and summer, and "fallen trees" are a layer further than "fallen leaves", not only the touch has a sense of dryness, but also the autumn atmosphere and a little dense meaning retained by the word "leaves" are also washed away.

According to the meaning of "falling trees and falling trees", of course, it means that the leaves are falling down, according to our usual thoughts, then the word "leaf" seems to be not omitted, for example, we have no problem saying this: "boundless fallen leaves are falling down", isn't it more clear? However, the genius Du Fu would rather omit the "leaves" of "leaves" than give up the "wood" of "leaves", why is this?

In fact, before Du Fu, Yu Xin had already said in "Wailing Jiangnan Fu": "Quitting the Dongting and falling wood, go to the Cuiyang Xijipu." Here we can see that the word "fallen wood" is indeed not accidental.

The subtlety of poetic language is different from the general concept, and it will be much worse if it is a little bit; It can be seen that poetic language cannot be based on concepts alone. Conceptually, "Konoha" is "leaf", and there is nothing to argue about; However, when it comes to the figurative thinking of poetry, the latter is not cared for, and the former is constantly evolving; With such a bold creativity as "Boundless Falling Wood Xiao Xiaoxia", aren't you afraid that people with dead eyes will mistakenly think that wood falls from the sky? However, our poet Du Fu would rather take this risk and create poems with vivid images that have been passed down through the ages; This adventure, this image, in fact, are all on this "wood" word, but the origin of this word is not easy to think?

At the same time, the concept of "wood" as a "tree" is precisely the shadow of "wood", "wood", "plank", etc., which often affects us to think more of the trunk of the tree and less often think of the leaves, because the leaves do not belong to the woody radical dismantling, so the "leaves" are often excluded from the sparse image of "wood", which is why this rejection implies the fall of the leaves.

Explanation of deciduous tree [deciduous tree].

In winter, the leaves of the trees are yellow and withered, such as willows, locust trees, etc.

Most deciduous trees have broad leaves, which are susceptible to damage in cold or dry weather. In contrast, most evergreen trees either live in warm, humid climates, or they have weatherproof needles. Of course, there are always exceptions in nature, such as the North American larch, which sheds its needles every fall, and the oak tree, which retains its leaves throughout the year even in relatively cool climates.

The shedding of leaves on trees that lose their leaves in the spring may also help these trees pollinate when spring comes. With no leaves in the way, the wind can move longer distances and reach more trees when the wind blows pollen.

For example, the camphor tree, which mainly grows in the south, its old leaves fall in the spring, and in recent years, many species have been introduced in the north, and its leaves still fall in the spring. The most representative conifers such as masson pine and cypress, whether they are born in the south or north, all lose their leaves after spring. And the most common willow, whether it grows in the south or the north, is autumn and winter deciduous leaves.

As for why some trees in the north lose their leaves in autumn and some trees in the south lose their leaves in spring, it is because many deciduous trees are suitable for growing in the northern environment, non-deciduous trees cannot survive in the north, while southern evergreen trees are more suitable for in the south, and its leaves are spring deciduous trees. In a word, evergreen trees lose their leaves in spring and are more suitable for planting in the south, and deciduous trees lose their leaves in autumn and are mostly planted in the north. Tree defoliation is an organic adjustment to the natural environment for survival.

In the northern winter, the leaves of the trees fall because the weather is cold, and the trees enter the hibernation period, stop feeding, and protect themselves in the cold wind and ice, and the leaves suddenly wither and fall off. The southern winter comes slowly, the temperature is not very low, the trees do not immediately enter the hibernation period, the absolute low temperature time is also short, the trees seem to sleep but not sleep, and there is a part of the offerings, so the trees in the south are a small part of the leaves, and the leaves that have not fallen are also squeezed out of the new leaves in the spring. The reason why some trees in the north lose their leaves in autumn and some trees in the south in spring is because many deciduous trees are suitable for growing in the northern environment, and non-deciduous trees cannot survive in the north, while the southern tree is more suitable for the south, and its leaves are spring deciduous trees.

Reduced photosynthesis: As the weather gets colder and the light hours are shortened, tree leaves receive light energy less efficiently for photosynthesis. To conserve energy and nutrients, trees actively break down their leaves and absorb the nutrients in them.

Reduced water transpiration: Leaves are the main part of water transpiration in plants, and in a cold and dry environment, the water is relatively insufficient. As a result, trees reduce water loss by reducing the number of leaves or shedding them.

Nutrient cycling: The leaves are rich in nutrients, such as nitrogen, phosphorus, potassium, etc. When trees drop their leaves to the ground, these nutrients enter the soil through decomposition and decomposition.

Microorganisms in the soil break down these nutrients into forms that can be absorbed and utilized by plants, thus promoting nutrient cycling and soil fertility.

In general, in the face of environmental changes and the need for energy regulation, trees adapt to the cold season by shedding leaves, and use the nutrients in the fallen leaves to promote ecosystem recycling and regeneration. This process is known as defoliation.

Similarities: **Same, all from the tree, the same shape, the same size, the fallen leaves are shed from the leaves, the leaf veins are almost the same, the leaf edge is the same.

Differences: The most fundamental difference is that the leaves are alive, the new leaves: bright green, live, soft and elastic, while the fallen leaves have completed a cycle of life, the new leaves contain a lot of chlorophyll and water, which can carry out normal metabolism, and the naturally shed leaves have less chlorophyll and water, and carotene will increase, and will gradually decay under the action of microorganisms.

The similarities and differences between fresh leaves and fallen leaves are: Similarities: the shape is the same, the veins are almost the same, and the leaf margins are the same.

Differences: new leaves: bright green color, live, soft, elastic new leaf content chlorophyll and water metabolism from shedding chlorophyll and water decrease, carotene increases the effect of micromatter gradually decay Different, leaves have life, and fallen leaves have completed a cycle of life New leaves contain a lot of chlorophyll and water, which can carry out normal metabolism, and the naturally shed leaves chlorophyll and water will decrease, carotene will increase, and will gradually decay under the action of microorganisms.

1 The images of "leaves", "trees" and "leaves" are not only not exclusive, but also very consistent, giving people the feeling of lush foliage and thick shade; And the "leaves" naturally have the yellowish and dry feeling of the fallen leaves, which brings the breath of the whole sparse autumn, and even makes people seem to hear the sigh of the departed, reminding of the wandering of the wanderer. "Konoha" belongs to the wind rather than the rain, and belongs to the refreshing clear sky instead of the heavy cloudy sky, a typical autumn character. "Leaves" is the unity of "wood" and "leaves", the interweaving of sparse and dense, a beautiful image of distance and affection.

The "fallen wood" is more spacious than the "wood leaf", and it even washes away the little dense meaning that the word "leaf" retains.

2 "Wood" has two artistic characteristics in its image: first, "wood" is more simple than "tree", as if it itself contains a deciduous factor; Second, "wood" not only reminds us of tree trunks, but also brings the color that "wood" suggests, which may be translucent yellow, and it may be dry rather than moist to the touch.

3 If the title is "On the Suggestiveness of Poetic Language", the whole article will have to be written differently, and it may have to be discussed from a theoretical point of view, and I am afraid that it will be written as a more theoretical academic **. The title of the article is "Saying 'Wooden Leaves'", and the article selects the image of "wooden leaves" in ancient poems as the topic, and in terms of structural arrangement, it first excludes the factors that ancient poets considered the refinement of words, and then explores the factors such as falling leaves from its use in autumn scenes, and finally touches on the suggestive issue of poetic language and explains it. In this way, the esoteric literary theory is attached to and infiltrated into the taste of reading the poems about "Konoha", and goes deeper layer by layer, exploring the subtleties and subtleties, which not only reflects the author's scientific attitude, but also fits the reader's reading psychology.

The proposed title of "Say 'Konoha'" should be a highlight of this article.
