Dietary characteristics of Millennium solar terms

The characteristics of Bailu solar term diet are drinking Bailu tea, eating sweet potatoes, eating rice wine, eating longan and eating ten kinds of white. Millennium is the 15 solar term in 24 solar terms, and the third solar term in autumn is the end of the application of the moon in the dry calendar and the beginning of the unitary month. When the sun reaches 165 degrees, it will be on September 7th to 9th in Gregorian calendar. Millennium is an important solar term, reflecting the cold growth of nature. As the weather turns cold, it is sunny and hot during the day, but the temperature drops quickly after evening, and the temperature difference between day and night is large.

During the white dew, the summer monsoon is gradually replaced by the winter monsoon, and the cold air changes from defense to attack. In addition, when the direct point of the sun moves south, the sunshine time in the northern hemisphere becomes shorter, the light intensity weakens, and the ground radiation dissipates heat quickly, so the cooling speed gradually accelerates. The Millennium basically ended the sweltering heat in summer, and the weather gradually turned cold, and the cold gave birth to dew condensation. The ancients used four seasons with five elements, autumn was gold, gold and white, and white was used to describe autumn dew, hence the name Bailu.

After the Millennium solar term, cold air became more and more active, and low temperature weather often appeared, which affected the heading and flowering of late rice. Huanghuai, Jianghuai and South China should seize the favorable opportunity of high temperature for shallow water irrigation. During the white dew period, the sunshine in South China decreased sharply compared with that in summer, and the rainfall showed the characteristics of low intensity, rainy and frequent persistence. Therefore, there is a saying in an agricultural proverb: The weather in Bailu is sunny, and Gu Mi is as white as silver. In this regard, we should take corresponding agricultural technical measures to reduce or avoid the harm of autumn rain, and pay attention to the prevention and control of rice blast, Sclerotinia sclerotiorum and other diseases.
