The autumn is the first solar term in autumn. Lili Qiu is the moment when the yin and yang qi in the eyes of the ancients began to transform, and it has always received much attention.

The autumn foreshadowing the footsteps of autumn is near, but at this time, the temperature in most areas in my country is still higher. Is the beginning of autumn, is it the beginning of autumn? What are the weather conditions around the country? What is the guiding significance of Liqiu for agriculture? Come to listen to Wang Liwei, a lecturer at the Department of Atmospheric Sciences of Shenyang Agricultural University, to interpret Liliu from the perspective of meteorology.

Is the beginning of autumn, is it the beginning of autumn?

On August 7 or 8 each year is the "Lizhou" in the twenty -four solar terms. Lili Autumn is the thirteenth solar term of the year, the first solar term in autumn. From the perspective of climate, the beginning of autumn is not the beginning of autumn. According to the standards of the seasons of modern climate, the average daily temperature in the second half of the year drops to below 22 ° C, which is the beginning of autumn.

Wang Liwei introduced that my country rarely enters the autumn area in "Lili Autumn". The earliest Heilongjiang and northern parts of Xinjiang will not enter autumn until mid -August. In the general year, the feeling of autumn began in early September in Beijing.

Before and after this year, due to the strong subtropical high -pressure control, my country's high temperature and summer weather will continue. As the subtropical high pressure position is lifted north, the center of gravity of high temperature will gradually from Jiangnan and South China to the north to the middle and lower reaches of the Yangtze River to North China. There may be phase high -temperature heat waves. While the high temperature spreads north, the humidity will also increase, and North China, Huanghuai and other places will usher in sweltering weather. It is expected that the average precipitation will still be less than the same period of the same year before and after the beginning of the autumn, and the average temperature will be higher than that of the same period of the year.

"Early autumn is cold and cold, stand in the late autumn and hot cows"

There are three years in Lijiu: when the cool wind is up, the two are white dew, and the three -waiting cold cicada shall sing.

After the beginning of the autumn, the wind is already cool. The wind of Liqiu is very important for traditional farming, and the folk spreads the saying that "the beginning of autumn is afraid of windlessness" and "the beginning of the autumn without wind is the year of the disaster." This is because the wind and rain of the beginning of autumn often come together, and at this time the autumn rain has a decisive impact on the collection of crops.

Second, Bai Lusheng said that because the temperature difference between day and night is large, in the early morning, there will be white fog, and the mist will be steaming. The cold cicada in autumn also began to sing.

There are many interesting farm proverbs, such as "early autumn is cold, and the autumn is hot and dead cow." What does it mean in the morning and evening of Lijiu? Wang Liwei introduced that it refers to the date of the lunar calendar, not the accurate time of the solar calendar. Normally, the autumn time generally appears in the two periods of time in the lunar calendar and July of the lunar calendar. It is late in July of the lunar calendar. This year's autumn time is the tenth day of July of the lunar calendar, and it belongs to the late autumn.

The farm proverb "June and autumn are tight, and the oil after autumn autumn in July" means that when the autumn autumn is in June, it means that the weather turns coldly in advance, and people will be busy in farm work. Time phenomenon. In July of the lunar calendar, this is very beneficial to the growth and development of the crops. Because the beginning of autumn is relatively late, the calories are relatively sufficient, which is more conducive to the growth of crops, but for the hot weather, for farmers, the body is sweating like a flowing oil. However, although tired, because the calories will improve the overall output and quality, seeing the hope of harvest, presumably farmers' friends are still happy.

Liliqiu in some areas of Sichuan is a good time to harvest rice, and we must seize the weather for harvesting.
