Xinmin Evening News (reporter Ma Dan) greeted the "mango seeds" today, the wind blew wheat into waves, and the birdsong began to be busy in summer. "Mangsang" is the "old nine" of the twenty-four solar terms, and it is also the third solar term in summer. In ancient times, "mango seeds" were also communicated with "busy seeds", and the "Seventy-two Hou Ji Xie of the Moon Order" mentioned that "the May Festival, that is, there are mango seeds and grains can be planted." "It refers to the harvest of crops (wheat) with mangoes, and the crops (rice) with mangoes as seeds. Therefore, the "mango seed" solar term is often said to be the "three summers" busy season, and most of the related agricultural proverbs are also mainly described as agricultural busy, or described the anti-related weather with the summer solstice, such as "mango seed busy seed, everything to be planted", "mango seed fire burning day, summer solstice rain ripples", "mango seed has rain, summer solstice sunny day" and so on.
Mango seeds are planted between The Little Man and the Summer Solstice, which is a festival in the transition period. During the mangosteen period, the sun will approach the northernmost point of its trajectory in the northern hemisphere day by day, and the longest day in the northern hemisphere will also arrive. In general, the rainfall is abundant during the planting season, and the temperature rises significantly. The average annual temperature in Shanghai is 23.9 °C, and the average precipitation is 83.3 mm (represented by Xujiahui Station, calculated from June 6 to June 20). Compared with the previous solar term "Small Full", the temperature has risen slightly, and the precipitation has increased significantly. In most cases, the "Mangzhong" solar terms in Shanghai have entered the summer but have not yet entered the middle of summer, and there will be no frequent high temperature weather above 35 °C, and the maximum temperature is usually around 33 °C. In the 145 years when Shanghai has official meteorological records, about one-fifth of the years experienced 1 to 2 days of 35 °C high temperature and an extreme maximum temperature of 38.0 °C in the "Mangzhong" solar term.
The significant increase in precipitation during the "Mangzhong" solar term is related to the rainy season in Shanghai in mid-to-late June. Shencheng's annual plum day is June 17. However, after entering the Mangzhong Festival this year, compared with the high temperature and high humidity of the traditional "Mangzhong" festival, Shencheng will basically be cloudy in the next four or five days, and the maximum temperature will oscillate between 30-33 ° C. Although the weather is getting hotter and hotter, the plum rain and heat have not yet arrived.
The ancients believed that during the mango planting season, the anode must be yin, when the ground is hot, the ground will be cold, and the praying mantis, Berau and the crow are all creatures that "feel the yin and move".
Mangsang Sanhouli,
A mantis is born;
The small praying mantises that are born in the forest in late autumn all break their eggs at this time
Erhou Shiming;
The yin-loving Burrow bird begins to appear on the branches and feels the yin and chirps
The three waited for the tongue to be silent.
In contrast to Berlau, the anti-tongue bird, which was able to learn the calls of other birds, stopped chirping because it sensed the presence of yin qi.
