Origin: Maple, with large leaves, similar to the size of a human palm, and slender petioles, which make the leaves swaying easily. When there is a slight breeze, the maple leaves will sway and rub against each other, making a "crash" sound, giving people a feeling of catching the wind and responding to it. Therefore, maple trees are named after the wind. The word "maple" has the same pronunciation as the word "wind", and "maple tree" means a tree that attracts and responds to the wind.

Deciduous trees, many varieties, flowering in spring, mostly granular yellow-brown and red. Leaves split palmately and turn red in autumn. Liquidambar formosana (also known as Hongfeng and Hongfeng) is unique to China, and there are many towering ancient maple in the Yangtze River basin.

Maple is also the national tree of Canada.

In addition, Acer is also called [Maple Leaf]. Such as: Acer truncatum, Acer truncatum.

The leaves of maple, the national flower of Canada. There are many maple trees in Canada, which is called "the country of maple leaves". For a long time, the Canadian people have deep feelings for the maple leaf and regard it as the national emblem. There are three red maple leaves in the middle of the national flag. The national anthem is "Long live the maple leaf" and the national tree is maple. Red leaves in Xiangshan [1]

Maple is a genus above botany, which formed Aceraceae independently earlier. The latest research results of molecular biology show that it should be classified as Sapindaceae. There are about 1 10 to 200 kinds of maple trees.

Maple is a green tree or shrub in summer. The leaves are palmately opposite. For example, Ye Feng's leaves are pinnate. There are two kinds of maple: hermaphrodite and dioecious. Some species are insect vectors, while others are wind vectors. The flower has five petals and the stamens are partially degenerated. The ovary is superior. There is a disc-shaped structure at the bottom of the flower to attract insects from non-wind-borne trees. The process of flowers is that the fruit is peeled off. Maple leaves change from orange to bright red in autumn, which is extremely bright.

[Edit this paragraph] Excerpt

The maple leaf in National Collection of Chinese Herbal Medicine is palmately 5-lobed, with a length of 13cm and a width slightly larger than the length. The three largest lobes have several protruding teeth, the base is heart-shaped, the top is medium green to dark green, and the axils below are hairy, which changes from yellow to orange or red in autumn. The bark is grayish brown and smooth, and furrows and scales appear with the growth of tree age. The flowers are yellow-green, small and headless, hanging on slender stems, and open with tender leaves in spring, showing an open inflorescence. The fruit has parallel wings and is 2.5 cm long. Height 30 meters, wide column, deciduous. Usually, the white sugar, brown sugar and rock sugar we eat are mainly boiled with sugar cane and sugar beet. Cooking sugar with sap secreted by trees is a new thing in China. In the forests of temperate regions of North America, there is a kind of sugar maple, commonly known as maple, which is the most famous in Canada. There are several varieties of sugar maple, such as sugar maple, silver maple and red maple. The first two kinds are famous for producing sugar. Maple can be used as building material or equipment material, musical instrument material, sculpture material, etc. , can also be planted for ornamental purposes. Plants used for logging and fire. Traditional Chinese medicine uses the root bark and branches in chicken feet, which are boiled in water when knee joint attacks. It is used in conjunction with ogapy (the author is not sure, this is provided by the data) during fracture; Has anti-inflammatory and detoxicating effects. Canadian maple (Acer truncatum) (also known as sugar maple) aggregates starch during the growing period. With the melting of snow in spring, enzymes convert starch into sugar, and sugar is dissolved by water absorbed by roots, forming a faint sweetness. Maple juice contains water (about 97%), minerals, organic acids and maple flavors. From the beginning of March, the sap will flow in the tree for 6-8 weeks to promote the growth of the tree. All trees produce juice, but maple has more and sweeter juice. There are more than 65,438+02,000 maple sugar producers in Canada. Canada's maple sugar production accounts for 85% of the world, and the United States accounts for 15%. Quebec (93.3%), Ontario (5.5%), New Brunswick (1. 1%) and Nova Scotia (0. 1%) are rich in maple sugar. According to Canadian data, the output of maple products in Canada in 2000 was 40 196 tons (88.4 million pounds), and the estimated agricultural output value was1515 million. Maple trees aggregate starch in the growing period.

All trees produce juice, but maple has more and sweeter juice. The main tree species producing maple sugar are sugar maple, red maple and silver maple. It is said that among the local 13 maple trees, only three kinds of maple trees, namely hard maple, black maple and red maple, can produce syrup. A big maple tree can collect 4 liters of sap every day. According to the preparation method of the invention, about 65438+/-0 liters of maple syrup can be prepared per 40 liters of sap. Interestingly, according to the owner, only maple trees in North America can produce maple syrup. Therefore, maple syrup has become a world-renowned specialty in Canada. From Quebec to Niagara Falls, the journey is 800 kilometers, which is the famous Maple Leaf Avenue in Canada. Toronto, Kingston, Ottawa, Montreal and other big cities are all distributed on this Maple Avenue. The famous St. Lawrence River originates from the rippling Lake Ontario and runs parallel to Maple Leaf Avenue. More than 65,438+0,000 lakes, large and small, are scattered around Maple Leaf Avenue, forming a beautiful landscape with maple leaves blooming on the lakeside, riverside and roadside. Bright maple leaves reflect blue sky and clear water, towns and villages, and the whole of Canada. Wherever you go, people will exclaim "It's beautiful here". This exclamation has actually been exclaimed many times in different places. A bird's-eye view of the maple leaf observation deck in Catino Park, a famous maple leaf viewing spot in Hull near Ottawa, shows the rustling river slowly flowing through the maple leaves. It's more than 500 kilometers from Ottawa to Montreal by car and then back to Ottawa from Montreal. The maple trees on both sides of the road are varied and graceful, and Youlong-like cars walk through the beautiful corridors. On the Yuan Ye, rows of maple trees, one after another, one after another, flowers and plants fly by. It's really a pity that I haven't enjoyed my eyes. It takes more than three hours from Ottawa to reach the provincial Al Kong Korm Park in Ontario. Al Kong Korm Park is a huge forest park covering an area of 7,725 square kilometers. In terms of scale, it ranks second among Canadian provincial parks with a history of 100 years. Roadways leading to natural lakes, jungles, swamps, rivers, cliffs and beaches crisscross, with a total length of 2400 kilometers. Among many maples, the representative ornamental values are as follows: 1. Deciduous trees of five-pointed maple (five-pointed maple, five-pointed maple) can reach a height of 20 cm.

Mainly produced in the Yangtze River basin, southwest, north China, southeast, west to Sichuan, with Shaanxi being the most widely distributed. 2. Acer truncatum (Acer truncatum, Acer truncatum) is a small deciduous tree, 7 cm -8 cm high, umbrella-shaped or spherical cap, with slender branches, purple or grayish purple. Leaf blade diameter is 6 cm- 10 cm, palmately parted by 5 cm-7 cm, usually 7-parted, split, lobes oval to lanceolate, leaf margin with serrations, only tufts of hairs below the axils, mixed flowers and purplish red.

Mainly distributed in East China and Central China. 3. Acer truncatum deciduous trees, up to10m. The crown of the tree is umbrella-shaped or obovate. Leaves palmately 5-lobed, lobes entire, lobes acute. Leaf base is usually truncated. The drupe is flat, the wings of the two fruits spread at right angles, and the wings are wider, equal to or slightly longer than the nutlet. Mainly produced in north and southeast China, but also distributed in Inner Mongolia, Shaanxi, Shandong, Jiangsu and An Wei. 4. Deciduous trees of triangle maple (maple, cockscomb maple), up to 20 meters high, with thin bark peeling and oval crown. Leaf apex 3-lobed or indehiscent, entire or slightly sparsely serrate.
