The beauty of appreciation
Castanopsis sclerophylla has a very long life, evergreen leaves and strong resistance to toxic gases such as carbon dioxide.
Castanopsis sclerophylla bears brown nuts with fine hairs on them. From flowering to fruiting, the flowering period of Castanopsis sclerophylla is generally in May, and < P > the fruit is ripe in October and will naturally fall off. Dr. Tong Lili said that Castanopsis sclerophylla found in Niushou Mountain is a community < P >, which is relatively rare in Nanjing. The leaves of the tree are oval or oval, the top gradually becomes needle-shaped < P >, the base is wedge-shaped or round, there are sharp serrations at the edge or above the middle, the back is pale and shiny, and the branches and leaves often rise in a < P > spiral arrangement, which has great ornamental value. The bark of Castanopsis sclerophylla is dark gray, showing a longitudinal crack.
sense of interest
patches of Castanopsis sclerophylla forest are unique to Niushou Mountain. Professor Tang Gengguo said that Castanopsis sclerophylla is the
"dividing tree" between the north and south of the Yangtze River, because it is endemic to the southernmost section of the Yangtze River, and it cannot grow further north. Niushoushan
In Castanopsis sclerophylla forest, the DBH of trees is generally 15-3cm, and the height of trees is about 1-2m. During the mountaineering,
experts also found that young branches of Castanopsis sclerophylla, with thin
roots and big leaves, have grown in the soil below the Castanopsis sclerophylla community, which is very lovely.
the joy of eating
Dr. Tong told the reporter that the fruit produced by Castanopsis sclerophylla is similar to chestnut in appearance, but contains starch, which can be used as "Castanopsis sclerophylla tofu". The reporter learned that the preparation method of "bitter tofu" is very simple: grind the pulp into fine powder, and < P > sieve out the coarse residue. Boil a pot of water, pour in the ground powder of Castanopsis sclerophylla when it boils slightly, and stir it evenly. After it thickens and solidifies < P >, take it out, spread it and cool it, and cut it into blocks. The "Tofu of Castanopsis sclerophylla" is a good product for heatstroke prevention and cooling. If you go to
to remove the hard shell, grind the nuts into paddles, heat them and make them into soft cakes, and then add seasonings to cook them carefully, which is the famous "bitter
cake". When you eat it in your mouth, it tastes smooth, delicious and slightly bitter.
Search route:
Castanopsis sclerophylla community is distributed in the middle and upper sections of the sunny slope of Niushou Mountain, and can be seen everywhere along the climbing steps. Experts say that this natural sub-forest is also mixed with deciduous broad-leaved forest, and the shrubs under it grow very well. One thing needs to be explained, there are many seedlings growing under the Castanopsis sclerophylla community now, and these seedlings need to be protected, so don't trample them during climbing.
Peach blossoms are brightly colored, and when they bloom, a tree of hongxia sets off the beautiful spring scenery to the fullest. Among ornamental peaches, the best
beautiful variety is Bitao, and among them, Red Bitao and Flower Bitao are the most beautiful. There are many famous peach blossom resorts in the north and south of our country, which decorate the great rivers and mountains of the motherland extraordinarily beautifully. For example, the "Peach Blossom Festival" in Xiangshan, Beijing every March and April is a good place to watch peach blossoms. Taking pictures in a sea of trees and peaches not only leaves a beautiful image, but also keeps the spring scenery.
Jinling Evening News reporter Yu Fei Wang Jun Jinling Evening News reported on Castanopsis sclerophylla, known as the "dividing tree" that marks the north and south of the Yangtze River. Experts said that Castanopsis sclerophylla should be planted in the forest, because it has good fire prevention performance and < P > can prevent soil erosion, and has obvious ecological benefits.
Cinnamomum camphora
Cinnamomum camphora, also known as Cinnamomum camphora, Cinnamomum camphora and so on, is one of the four famous trees in the south of the Yangtze River.
Cinnamomum camphora is a subtropical tree species, mainly distributed in the south of the Yangtze River, and it is an evergreen tall tree of Catalpa in Lauraceae. Flowers in early summer, yellow-green, panicle, wide crown, lush foliage, shady everywhere, magnificent momentum, is an excellent street tree and shade tree. Cinnamomum camphora has the characteristics of temperature resistance, corrosion resistance and insect repellent because of its special aroma and volatile oil. It is an ideal wood for expensive furniture, high-grade buildings, shipbuilding and sculpture. Camphor for daily use is a white crystal distilled from the roots, stems, branches and leaves of Cinnamomum camphora. It is colorless, transparent and has a cool fragrance. It is used for moth prevention and is also widely used in medicine and chemical industry.
In the folk, people often regard Cinnamomum camphora as a landscape tree and a geomantic tree, which means avoiding evil spirits, longevity and good luck. Cinnamomum camphora is favored by the majority of urban and rural residents, and Hangzhou, Yiwu, Maanshan and other cities have chosen it as the "city tree".
Cinnamomum camphora is very distinctive. Its bark is rough, but its texture is very uniform. It has never been mottled by poplars and has no tumor nodules of willows. Branches and trunks are divided into two, and the two are divided into four. They will not cut corners or gild the lily. The shape of the crown is spherical, and a beautiful curve is drawn in the sky. Cinnamomum camphora is like Su Dongpo's calligraphy. It is round and continuous, handsome and elegant, but it is quite satisfactory. If it is a hillside full of camphor trees, it is simply a peerless tablet of Su Dongpo. Therefore, people who study art like to use camphor tree as the object of sketch. What is even more rare is that camphor tree has a special fragrance, which can repel insects, so it is almost unnecessary for gardeners to spray pesticides. These two days, I feasted my eyes on my business trip in Jiangxi, which is famous for its camphor trees, and greatly satisfied my special hobby, which is insufficient for humanity. Camphor trees are everywhere in Jiangxi, and there are many old trees over 5 to 6 years old, which are scattered in villages, rivers and hilltops.
Populus
1. Populus is a typical representative of Populus in Salicaceae.
morphological characteristics:
trees or shrubs.
simple leaves alternate with stipules.
the flowers are unisexual, and the flowers are in panicles.
each flower has a bract, no perianth and a disk or gland. Stamens 2, pistil 1, ovary 1 locular superior. Capsule, 2-4-valved, small seeds, many, long hair at the base.
Living environment:
Poplar is the most common tree in northwest China. Wherever there is grass, there is the shadow of poplar. Poplar is not very particular about living conditions. On the roadside, beside the ridge, wherever there is loess, there is her survival. She doesn't chase after rain or lust for sunshine. As long as she can give a little water to the hardened land, a branch of poplar will take root and sprout. Just move a little space for weeds to live, and she will decorate the yellow land and hold up a piece of green. She doesn't need to be fertilized or watered like a delicate lawn. As long as she doesn't use a knife and axe to cut it down and gives her a relaxed environment to absorb free air, she will stand tall and upright. She never says no to the land where she grows. She is not a vine, rooted in barren soil, happy-go-lucky, otherwise, because she belongs to the grassroots. Although poplar was born in poverty, it is the most concerned about the quality of life. There is still ice in the soil, and there is still a chill in the spring breeze. Her branches have sprouted green buds. Under heavy pressure, every bud and leaf of her is striving for progress, never bending down to beg, and there is no kitsch face. In the autumn wind, although the leaves have been stripped off, the thin branches are still full of essence, with their branches up and their heads held high. In the severe winter, facing the sword, she still stood in the cold yellow land, with proud branches, trees without words and trees with sounds. At this time, the noble flowers and plants, however, are in the greenhouse, receiving nutrients sent to the leaves and roots, lazily killing the days without blood.
Life habit:
The temperament of poplar is civilian, but it is the richest. She can be used as firewood, furniture, purlin and farm tools. Like the yellow land where she grew up, she is unpretentious. In the eyes of some people, she will almost forget her existence. But for the barren and poor yellow land, she is a brave man. Throughout the year, she stays behind and decorates, reducing the poverty and loneliness of the yellow land and increasing the vividness and beauty, because her roots have been connected with the yellow land as a whole. Poplar didn't think of transplanting and migration, even if her fallen branches and leaves were corrupted by soil, it would add some nutrients and vitality to this yellow land. Under the thick loess, the immortal life of poplar is surging, and the yellow land is crisp and green.
ii. Poplar:
The representative work of French painting master Paul Cézanne (1839-196). The representative figure of the later impressionist school, who pursued the form of expression all his life and made new creations in the use of color and modeling, was called "the father of modern painting". Cezanne opposes the separation of sketch and color in traditional painting concepts, and pursues the perspective of objects through color. His pictures are harmonious and beautiful in color.
in early April p>1879, Cezanne moved to Meilun, a small town located 3 kilometers southeast of Paris, not far from Fontainebleau. Every day, he takes his easel and paint and chooses the scenery for painting, and his special preference is a small village called Mansi nearby. What pissarro loves is rural farming and the daily life of rural residents; Cezanne, on the other hand, is completely different. His single-minded concern is the natural scenery that is not disturbed by people or animals. He chose the scenery not on the basis of its beauty, but from the perspective of lines, colors, light and space to see if it meets the standards of pure modeling. In the quiet countryside, he made some adjustments to the style he had formed since he became an adult, and used a long and oblique brushwork to draw a pattern similar to a carpet network on the screen. This network pattern in which light circulates is the main feature of his works such as Poplar painted in Pontoise the following year.
The scenery Cezanne painted in this painting is near Ma Gourville Castle in Patty village, not far from Pontoise; For more than ten years, he often came here to paint. After arriving at the roadside overlooking the scene, he began to construct the picture space, regardless of whether it had realistic effects. The path planted with poplars has an "S" curve, and he uses this lively curve to arrange different levels of its composition. The scene in the depth of the picture is therefore smaller than the scene in the front of the picture; However, unlike illusion or photography, the scenery he painted has no vague feeling and its color is no less. The mechanical effect of this geometric structure is alleviated by light and air passing through it, and the blank left by using light pigment between inclination and brush strokes makes this movement of light and air more obvious. The patterns drawn with uniform brushwork are very energetic, which makes the towering trees whose leaves are shaking in the wind show a sense of rhythm close to music.
When Cezanne painted his landscape paintings, the pigments used in his palette were very limited, that is, light green and Siena earth color were mixed, and in addition, they were used to represent the blue and white of the sky and the stone fence beside the well, and the latter two colors were painted on the center and right side of the picture. He drew slowly, sketching out the pattern directly with pigment, without drawing a sketch showing the outline of the picture first. The criss-crossing brushstrokes are in a perfect balance with each other, which makes the painted scenery give people a sense of stability, which is very close to the traditional concept of painters in the seventeenth century. He once wrote: "I want impressionist painting to become a solid art, which will last forever like the works of art collected in museums."
Cezanne, who is integrated with nature, conveys to us an eternal impression from nature. When he asked us to think about the empty and silent world he painted, his identity as an emotional transmitter was also confirmed.
