The feeling of Qujiang in early autumn: (Don Bai Juyi) left Xia Yun, and the cool wind rose from the pool. Autumn came again, and the half-opened lotus Zhu Yan was carefree. Living in endless daylight is not as good as mountains, and young people are eager for water. Kate and Hongzun are about the same age as autumn. I was very sad this autumn last year, and I came back here this autumn.
Extended data:
1, Introduction of Heat Treatment in Summer
Summer is the fourteenth of the twenty-four solar terms, and autumn is the second. Dou Zhiwu (Southwest); The solar meridian reaches150; August 22-24 of the Gregorian calendar every year. Summer has arrived, which is the "last summer" in the "three summers" of hot and hot weather, which means that the hot and difficult weather is coming to an end.
After the summer heat, the direct point of the sun continued to move southward, the solar radiation weakened, the subtropical high retreated southward, and the summer heat gradually disappeared. Thunderstorm activity is not as active as summer, and the general trend of rainstorm in all parts of the country is weakened. There are many folk activities in summer, such as eating ducks, setting off river lanterns, opening fishing festivals, decocting medicinal tea and offering sacrifices to the land.
2. Agricultural activities
In summer, most parts of southern China are in the busy season of harvesting mid-season rice. Generally, during the summer solar term, the sunshine in South China is still abundant. Except for the western part of South China, there are not many rainy days, which is beneficial to mid-season rice cutting cotton and spitting.
During the summer season, fruits and crops in most areas of China gradually entered the mature stage, and farmers stepped up their picking, seized the farming season, and carried out field management such as rice fertilization and weeding. "The summer valley is getting yellow, be careful of the strong wind."
After summer, the temperature difference between day and night increases. Because the night is cold and the day is warm, the nutrients absorbed by the crops during the day are stored at night, so the crops mature quickly. "The fields change overnight in summer", "There is no valley for three days in summer", "Three Dynasties of rice in summer" and "Summer rice is full of fields, and everyone repairs warehouses", all of which indicate that the crops will be harvested soon after the summer solar term.
3. Astronomical calendar
In summer, the bucket handle of the Big Dipper points southwest (E position). When the sun reaches longitude 150, the node time is around August 23rd in Gregorian calendar.
In summer, the direct point of the sun has moved from 23 26' north latitude to1128' north latitude. At this time, if you watch the Big Dipper at night, you will find that the curved bucket handle still points southwest. The arrival of the hot summer also means entering the second half of the dry calendar.
