What time is the Millennium solar term?

The solar term of the Millennium is 5: 26 +0 seconds on September 8, 365438.

After entering the Millennium solar terms, the summer monsoon is gradually replaced by the winter monsoon, and the cold air gradually moves southward frequently. In addition, the position where the sun directly touches the ground moves south, and the sunshine time in the northern hemisphere becomes shorter and the sunshine intensity weakens. At night, it is often partly cloudy and sunny, and the ground radiation dissipates quickly, so the temperature drop is gradually accelerated. There is a saying called "Qiu Qiu in a thousand years, it is cold all night."

After the Millennium, the temperature difference between day and night gradually widened. Although the temperature is high at noon during the day, it is already very cold in the morning and at night. According to the standard of "average weather temperature" proposed by modern scholar Zhang Baokun, the average weather temperature is 10-22℃ in spring or autumn. According to this standard, from the beginning of the Millennium solar term, all localities began to enter autumn one after another. At this time, the temperature difference between day and night in China can reach 8℃- 16℃, so the temperature difference in a year is large.

Farming activities in Millennium Festival

"White dew" represents the change from heat to cold, and everything is born with cold, gradually falling and maturing. The Millennium season is a busy season in China. Millet, sorghum and soybeans began to be harvested in the northeast, and new cotton was picked in some places; At the same time, it is necessary to select seeds for cotton, corn, sorghum, millet and soybeans. , timely stubble cleaning, soil preparation, fertilizer delivery, and rushing to plant wheat.

In North China, it is also the busy season of autumn harvest, and all kinds of autumn harvest crops have matured and started to harvest; At the same time of autumn harvest, we should pay close attention to sending manure and ploughing the land, and make preparations for planting wheat as soon as possible. Winter wheat has been planted in the northwest of China. In the southwest, when the dew season comes, there is a busy scene everywhere. Because of the "white dew", millet is full of yellow rice and millet, so we have to harvest it quickly.

Late autumn crops, such as corn and sweet potato, should strengthen field management to promote their early maturity and avoid the harm caused by low temperature frost. In central China, late rice and middle rice should be harvested quickly, and summer corn should also be harvested. Cotton should be picked in batches, and water management should be strengthened for late corn. In addition, we must pay close attention to leveling the land and preparing to plant wheat.
