The origin and significance of mango

"Ear seed" is the ninth of the 24 solar terms, and it also marks the maturity of wheat and the harvest of sickle. People often say, "busy farming", whether it is crops or anything in life, I advise you to use the "busy farming" solar terms to sow what you should sow, so that after autumn, you will certainly gain something!

The origin and meaning of mango solar terms;

In ancient China, mango seeds were divided into three stages: "One stage was when mantis was born; Second, wait for Peng to start singing; The third-class tongue is silent. " In this solar term, the eggs laid by mantis in late autumn last year, because they felt the birth of Yin Qi, broke their shells and gave birth to little mantis; Shady shrike birds began to appear in the branches and sing in the shade; On the contrary, mockingbirds, who can learn from the songs of other birds, stop singing because they feel the appearance of Yin Qi.

Ear seed means the maturity of wheat and other crops, and it is a solar term reflecting agricultural phenology. By the time of the awning, the wheat harvest season in Sichuan Basin has passed, and the transplanting of mid-season rice and sweet potato is coming to an end. In most areas, the mid-season rice has entered the green stage, and the seedlings are green and full of vitality. The poem "The east wind dyed 3,000 hectares, and the herons kept coming and going" vividly described the beautiful scenery of the field at this time. In the awning season, the medium rice that has not been transplanted in the basin should be planted quickly; If it is postponed again, the vegetative growth period of rice will be shortened due to the increase of temperature, and the growth period will be easily affected by drought and diseases and insect pests, and the yield will inevitably be low. Osmunda japonica should be transplanted before summer at the latest; If it is sown too late, not only will the influence of drought be aggravated, but the temperature will also drop in Qiu Lai, which is not conducive to the expansion of potato pieces and the yield will be significantly reduced. This is the truth of the agricultural proverb "busy planting".

Mango is a very busy solar term. Shaanxi, Gansu and Ningxia are "busy planting seeds and breeding them in the summer to the valley of the sun". Guangdong is "the awn seeds are heavy in summer (referring to transplanted plants again)". Jiangxi is "you can't plant seedlings in the first three days, and you can't plant seedlings in the last three days." Guizhou is "it is useless to plant awns if you don't plant them." Fujian is "awning edge, good for indica rice, over awning, good for glutinous rice". Jiangsu is "the mango is a treasure, and the summer solstice is grass" and Shanxi is "mango, mango, everything". "The seeds of awn and millet are planted in the valley urgently". Sichuan and Shaanxi are "busy farmers in front of the tent and busy planting beans behind the tent". As can be seen from the above farming, China is busy planting crops from south to north through the ear planting festival, and the busy farming season has reached a climax.

"The wheat planted in April comes first and the wheat planted in May comes last", which means that the wheat in North China is mature in April and immature in May. Why? This is the same as "peach blossoms bloom in February and don't bloom in March", which is caused by the lunar calendar algorithm. According to the lunar calendar, a year is actually 354 or 355 days. This is10-1day less than the number of days the earth goes around the sun, so it needs to leap every three years (sometimes every two years) to make up for the shortage of days. In leap months, the solar term is either advanced or postponed, so sometimes it is in April and sometimes in May. Farmers in China are well aware that crops are sown in early April due to early spring and early solar terms. Planting crops before awning and after the solar term in June is a scientific planting method of "dead solar term living method"

Climatic characteristics of Miscanthus;

There is abundant rainfall, and the temperature rises obviously in the awning season. Common weather disasters include tornadoes, hail, strong winds, heavy rains and droughts.

rain

The Yangtze River is in the ear sowing season, and the Huanghuai Plain is about to enter the rainy season. If there is continuous rain, strong wind and hail before and after ear planting, and the wheat can't be harvested, threshed and stored in time, it will lead to the lodging, grain dropping, germination and mildew of the ear, "rotten wheat field" and destroy the crops in front of us.

After the awning, the monsoon rain belt in the southeast of South China is stable, which is the most rainy season in a year. The middle and lower reaches of the Yangtze River have entered the rainy season one after another, with more rainy days, more rainfall, less sunshine and sometimes lower temperatures.

In the awning season, rice, cotton and other crops grow vigorously and need a lot of water, and moderate plum rain is very beneficial to agricultural production; In the years when the plum rains are too late or too little or even "empty plum blossoms", crops will be threatened by drought. However, if the rainy days are too early, too many rainy days and too few long-term rainy days, it will also have a negative impact on agricultural production, especially if the rainfall is too concentrated or heavy rain will cause floods.

Southwest China has also entered the rainy season of the year since June. At this time, the hail weather in the southwest and western plateau areas began to increase.

temperature

During this period, except for the Qinghai-Tibet Plateau and the northernmost part of Heilongjiang, people in most areas can generally feel the summer heat. Nenjiang River, located in the north of Heilongjiang Province, is the hottest day in 197 1 ~ 2000. 1℃, appearing in the awning period.

In June, whether in the south or the north, high temperature weather above 35℃ may occur, and high temperature weather above 40℃ may also occur in Huanghuai area and the eastern part of northwest China, but it is generally not a continuous high temperature.

In China's southern provinces of Taiwan Province, Hainan, Fujian, Guangdong and Guangxi, the average temperature in June is around 28℃. If the air humidity is high before the thunderstorm, it is really stuffy and hot. Sometimes it is necessary to issue a high temperature forecast to the public to remind people to prevent heatstroke, air conditioning disease and acute gastroenteritis.
