Skill the weather, know the agriculture

Reflecting the mid- and long -term weather forecast reflects the mid- and long -term weather

Cheng Lin, deputy director of the Grain Crop Office of the Henan Provincial Agricultural and Rural Hall, introduced that on the basis of long -term observation of natural phenomena, the ancients summarized some farm proverbs. Through the changes in animal response or natural phenomena Essence

For example: "Lizhu has no rain and three volts, and Chongyang has no rain and winter." This is a connection to the two natural phenomena to predict the weather in the next period of time. According to the statistics of the meteorological department in the past 10 years, the year of precipitation on the day of Lixia in Henan Province was only 2020 a year. The average temperature of the three volts of the year was 0.8 degrees Celsius lower than the year. Other years.

With the advancement of science and technology, the natural phenomenon reflected by farm proverbs has been quantified by meteorological elements. Jackie Chan believes that the current professional and precise weather forecast technology of the information age is no longer based on farm proverbs. However, farm proverbs that are reminded by agricultural activities are still widely used. These farm proverbs are strong and scientific, and their language is concise and simple, which is convenient for people to read it verbally.

Modern meteorological forecast trends are generally consistent with solar terms

"Although the foundation of modern weather forecasting is to make full use of the various algorithms in the era of numerical forecasting, meteorological theory, observation system, information dissemination, and big data era, the forecast results and trends are generally consistent with the ancient soil farmers' proverbs." The chief forecaster Zhang Jing introduced that the main flood season of Jiangsu is from May to October. From the historical average precipitation from 1991 to 2020, the waterfall in Jiangsu Province in early May of May is between 25 and 37 mm. Compared with significantly increased in late April. This just corresponds to the two solar terms of solar terms of "Lixia Xiaoman, River Water Manchu" and "Lixia Snake out of the hole, ready to flood prevention".

"The summer solstice summer solstice, there will be heavy rain." The temperature rose significantly after Lixia. In Jiangsu, high temperatures of 35 degrees Celsius in early May increased significantly, and the convection of precipitation was significantly enhanced. From the rainstorm day in May of the previous year, this sentence can also be verified. For example, on May 7, 2020, some areas of Huaibei, May 8th, and some areas along the Huaihe River on May 14th in some areas of Huaihe River. On the 15th, heavy rainfall was reached along the southern part of Jiangsu. Early analysis and forecast brings convenience to agricultural arrangements and production and life.

Emeating farmers in different regions are very regional characteristics

my country has a vast territory, the natural conditions in various places are very different, and the climate characteristics are different. Therefore, solar terms in different regions have also been adapted to local conditions and rich regional characteristics. Tang Zhiqiang explained the example of Lixia and Xiaoman solar terms:

The farm proverb of "Ligue Summer Southeast Wind and Drought in the middle of June" is popular in the northwest, which means that if Lixia scrapes the southeast wind earlier, it means that the temperature has increased earlier than in previous years, less rainwater, and long -term high temperature evaporation, then high temperature in the lunar calendar will appear in June of the lunar calendar. The probability of drought is relatively high, which will affect the wheat's pregnancy. There are many farm proverbs in South China. According to the wind direction of the beginning of the summer season, it predicts the future rain and drought. Guangdong has "Lixia South Wind and Drought, there are many rain and water in the north, and the northeast wind is large." "There are" Lili Summer Beifeng Fish Ponds, Lili Xia East Winds to lead Lei Gong "," Lixia Nanfeng, Fireframe (referring to the drought of paddy fields) ", and so on. These farm proverbs have played a positive role in guiding local agricultural production and farmers' lives. (Reporter Shi Fang Ma Yuefeng Yao Xueqing)
