How can the leaves of the maple tree be red?

Stress response: The reddening of the maple leaves is actually the result of the maple tree's response to stress in nature, and the reddening actually acts as a sunscreen, allowing the leaves to stay on the tree longer, allowing the tree to absorb more nutrients. Studies have found that nutrient stress, especially nitrogen deficiency, causes maple leaves to turn red earlier and more transparently.

The red maple leaves are red and look a lot like the palm of the hand, and the edges of the leaves are jagged and red maple.

On our side it is called the red maple tree, which is a type of small tree. It is produced in our Jiangsu, Henan, Hubei and other places. The red maple can grow up to about four meters, the branches are numerous and very smooth, the leaves are fan-shaped, and the leaves are bright red and particularly beautiful.

Red maple is a tree that likes moist soil, the weather is relatively warm and the environment is very cool, likes the sun but can not be exposed to the sun, the sun will make the bark on the branches and trunk all fall, like a more shady place, the soil requirements are not high, like the land is fertile and not a place where water can grow. And the red maple is an ornamental tree, there are many people like to plant the red maple in the garden, but most of them are planted on both sides of the road or in parks and gardens, etc., but there are also people who like to make the red maple into a bonsai cut into a variety of shapes, such as leaning on the stone, dry, cliff and other shapes, placed at the door or on the balcony is particularly perfect and beautiful.

Red maple is a red-leaved greening foliage tree species, also known as red-leaved feather maple, a variant of Acer chinensis of the maple family, is a small deciduous tree, the tree is 2-4 meters high, the branches are slender and smooth, purple-red. Leaves palmate, 5-7 deeply cracked, 5-10 cm in diameter, lobes ovate-lanceolate, apex caudate-pointed, margins heavily serrate. The shape characteristics of the leaves are shown below.

Red maples are bright red in the spring when they sprout, gradually turn green in the summer, and turn red in the fall. The shape of the river is like a chicken claw, also called a chicken paw maple.

Sprout and grow into leaves in spring.

In summer, the trees are shady and grow vigorously.

In autumn, the green leaves change color and red.

The leaves begin to lose their leaves from late autumn to winter.

The common colors of maple leaves are: green, yellow, and red.

Maple leaves change color depending on the season. In spring and summer, maple leaves are green, and chlorophyll is much more abundant in the leaves than other pigments, so the leaves show the green color of chlorophyll, and the color of other pigments is not visible.

When autumn comes, the maple leaves begin to lose their leaves, and before the leaves fall, the trees no longer produce as much chlorophyll as they do in spring and summer, and existing pigments, such as chlorophyll, will gradually break down. In this way, as the chlorophyll content gradually decreases, the colors of other pigments will gradually appear on the leaf surface, so that the leaves will show yellow, red and other colors.

Maple leaf chlorophyll gradually decomposes as the temperature drops, revealing the appearance of other pigments. The sugars stored in the maple leaves will also be broken down and converted into anthocyanins, making the leaves more bright red.

The maple leaf is fiery red, and the fiery red symbolizes enthusiasm and unrestrainedness, and the leaf shape of the maple leaf is different from other leaves, which is very special and unique. The ornamental nature of maple leaves is very strong, there are four most famous maple viewing spots in China, and they are called the four major maple viewing resorts in China, they are Beijing Xiangshan, Suzhou Tianping Mountain, Nanjing Qixia Mountain, Hunan Changsha Yuelu Mountain.

The degree to which maple leaves turn red is related to factors such as time, drought, pollution, and especially the lack of nitrogen. The reddening of maple leaves is actually the result of the maple tree's response to stress in nature. The reddening reaction actually acts as a sunscreen, allowing the maple leaves to stay on the tree longer, allowing the tree to absorb more nutrients.

Studies have found that nutrient stress, especially the stress of nitrogen deficiency, makes maple leaves red earlier and more transparently.

The process of changing the maple tree throughout the year:Maple leaves are young in the spring when the temperature rises, and the color of the leaves is tender green. In the later stage, the maple leaf slowly grows into a pinnate or palm-shaped compound leaf.

In summer, the leaves are wide and change color to dark green. In autumn, when the temperature drops, the leaves slowly turn fiery red, which is also the most beautiful time. In early winter, the leaves begin to fall, turning crimson when they fall to the ground, and by December they are mostly gone.

It blooms from April to May and bears fruit from September to October. The shoots are brownish-red to brown with small holes, and the branches are black-brown or gray in winter.

The maple leaves turn red. The leaves contain a lot of chlorophyll, so the color is green. In autumn, when the weather gets colder, the growth of trees slows down, and the chlorophyll in the leaves gradually decreases, until only lutein remains, and the leaves turn yellow.

Maple leaves contain a special substance - anthocyanins, which are the opposite of chlorophyll. As the weather cools, the number gradually increases, causing the maple leaves to turn red.

1. Why do the leaves turn red?

Red maple leaves contain a lot of pigments, in addition to chlorophyll, there are lutein, anthocyanins, carotene and other handicrafts, when autumn comes, the temperature gradually decreases, the function of chlorophyll is hindered, gradually decreased, replaced by other pigments shown, the color of the leaves will show red.

2. Is it always red?

The leaves of the red maple are not always red, and when they first grow, they may not be particularly red. In the later maintenance, if there is a problem with the maintenance method, it will also cause the leaves of the red maple to not be red.

3. The reason why it is not popular.

1. Improper watering: The leaves of the red maple are not red, probably because of improper watering, and the potting soil should be kept moist during the growth period, and the potting soil should be watered regularly to maintain the leaf color.

2. Lush branches and leaves: If the branches and leaves grow particularly lush and dense, it will also lead to bad leaves, which need to be properly pruned to increase light transmittance.

3. Lack of nutrients: If the nutrients are insufficient, it will also cause the leaves to not be red, so you should fertilize properly, and be careful not to apply too much nitrogen fertilizer.

3. Insufficient light: red maple is a light-loving plant, suitable for growing in a sunny environment, if there is a lack of sunlight, it will also cause the leaves to not be red.
