Information about poplars

Poplar 1. Poplar is a typical representative of poplar in Salicaceae. Morphological characteristics: trees or shrubs. Simple leaves and stipules alternate. Flowers unisexual, in a panicle. Every flower has bracts, but no perianth, disk or gland. 2 stamens, pistil 1, ovary 1. Capsule, 2-4-valved, with small seeds, and most long hairs at the base. Living environment: Poplar is the most common tree in Northwest China. As long as there is grass, there is the shadow of poplar. Poplar is not very particular about living conditions. Roadside, beside the ridge, where there is loess, there is her survival. She doesn't chase rain, and she doesn't long for sunshine. As long as she can water the hardened land a little, a poplar will take root and sprout. As long as a little space is set aside for weeds to survive, she will decorate the yellow land and hold up a piece of green. She doesn't need to fertilize and water like a delicate lawn. As long as she doesn't use a knife and axe to cut and gives her a relaxed environment to absorb free air, she will hold her head high. She never rejected the land where she grew up. She is not a vine, rooted in poor 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 the spring breeze is still chilly. Green shoots have sprouted from her branches. Under the heavy pressure, every bud and leaf of her is striving for progress, never bending down to beg, and there is no flattering face. In the autumn wind, although the leaves have been stripped, the thin branches are still full of essence, and the branches stand upright and hold their heads high. In the severe winter, facing the sword, she still stands on the cold yellow land, with proud branches, silent trees and voices. At this time, the noble flowers and plants, however, are in the greenhouse, receiving the nutrients sent to the leaves and roots, lazily killing the bloodless days. Living habits: 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, it is unpretentious. In some people's eyes, she will almost forget her existence. But for the barren yellow land, she is a brave person. Throughout the year, she stayed and decorated, which reduced the poverty and loneliness of the yellow land and increased the vividness and beauty, because her roots have been integrated with the yellow land. Poplar did not expect to transplant and migrate, even if her fallen branches and leaves were corroded 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. 2. White Poplar: the representative work of French painter Paul Cézanne (1839- 1906). The representative of the post-impressionism, who pursued the form of expression all his life, made new creations in the use of color and modeling, and was called "the father of modern painting". Cezanne opposes the separation of sketch and color in traditional painting concept, and pursues the perspective of objects through color. His paintings are harmonious and beautiful in color. 1879 In early April, Cezanne moved to Meilun. The town is located 30 kilometers southeast of Paris, not far from Fontainebleau. Every day, he takes an easel and paints to choose the scenery he wants to paint, and his special preference is a small village called Mansi nearby. Pissarro loves rural farming and the daily life of rural residents; Cezanne is completely different. He is fully concerned with the natural scenery that is not disturbed by people or animals. His choice of scenery is not based on its beauty, but on whether it meets the standard of pure modeling from the perspective of lines, colors, light and space. In the quiet countryside, he made some adjustments to the style he had formed as an adult, and drew patterns similar to carpet nets on the screen with long and oblique brushwork. This reticular pattern of light circulation is the main feature of his works such as Poplar painted in Pontoise the following year. The scenery painted by Cezanne in this painting is near the castle of Ma Gulville in Patty village, not far from Pontoise; For more than ten years, he has often come here to paint. When he reached the roadside overlooking the scene, he began to construct the picture space, regardless of the realistic effect or not. The path planted with poplars has an "S" curve, and he uses this lively curve to arrange different levels of its composition. Therefore, the scene deep in the picture is smaller than the scene in front of the picture; However, unlike illusion or photography, the scenery he painted has no vague feeling and its color is not inferior. The mechanical effect of this geometric structure is alleviated by the light and air passing through it, and the blank left by the use of light pigment between inclination and brush strokes makes this movement of light and air more obvious. The patterns drawn with unified brushwork are very energetic, which makes the towering trees with swaying leaves in the wind present 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 tone were mixed, and they were also used to represent the blue and white of the sky and the stone fence beside the well. The latter two colors were painted in the center and right side of the picture. He drew slowly, sketching the pattern directly with pigment, without drawing a sketch showing the outline of the picture first. The criss-crossing brushstrokes achieve 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 17th century. He once wrote: "I want impressionist painting to become a solid art, as long as the works of art collected in museums." Cezanne, who is integrated with nature, conveys an eternal impression from nature to us. When he made us think about the empty and silent world he described, his identity as an emotional transmitter was also confirmed.
