1, "Qiu Lai": Bamboo Watching the Moon, Ye Huang, Qiu Lai, Tian Lao, Meng Han. Where are you, I'm here, I cry, the string is broken, the moon is bent, the water drops, the autumn frost is white, the night is dry, and the flowers are half late.
2, "First Frost": A few cold dog barks-after that. Outside the window, or farther away, the footsteps of the wind came faintly. Yes, all night, the wind kept bringing darkness to the mountain village. When I got up in the morning, I saw the sweat from the wind condensed into frost on the yellow grass.
3. The depth of autumn: Sleeping at night, the stars and the moon are still awake, the mountain village is sleeping, the trees and the wind are still awake, and the wind is the palm of autumn. Touched again and again, the tree is hurting-a nightingale is calling: it's night, and the ruler suddenly appears again. The depth of autumn was measured.
4. Autumn Day: Lord, it's time. Summer is its peak. Put your shadow on the sundial and let the wind blow through the pasture. Let the last fruit of the branch be full; Give them two more days of fine weather in the south, let them mature and squeeze the last sweetness into spirits. No one needs to build a house at this time. Whoever is lonely at this time will be lonely for a long time. He will wake up, read books, write long letters, wander and degenerate.
phenology,bioclimatology
It is autumn in beginning of autumn so far, which means that precipitation and humidity are at the turning point of the year, and there is a tendency to decrease or decrease. In nature, everything begins to grow from lush to rich and mature. Autumn is the harvest season, and many plants mature in autumn. In autumn, in nature, the qi of yin and yang begins to change, and the yang gradually declines and the yin gradually grows.
As the temperature gradually drops, the leaves of many deciduous perennial plants will gradually change color, wither and fall off, leaving only branches for winter. Panicum miliaceum will come to the end of his life, wither and die. Seasonal variation covers many aspects of climate characteristics, and it is not accurate to judge autumn only by temperature.
