In 2013, Xiaoman was a few months and days

When is Xiaoman this year? On May 21 or 22 of each year, it is considered a small full sun when it reaches 60° of the ecliptic path. Therefore, the date of Xiaoman 2013 is May 21.

Xiaoman is the second solar term of summer, which means that the grains of summer crops begin to fill full, but they are not yet ripe, but they are only small and full, not yet full. "Seventy-two Candidate Explanations of the Lunar Order": "In April, the small one is full, and the thing is so small and full.

At this time, the grains of summer crops such as wheat in the northern part of the country have begun to be full, but they have not yet matured, and they are about the late stage of milk maturity, so they are called Xiaoman. At this time, it is advisable to pay close attention to the prevention and control of insect pests in wheat fields to prevent the attack of hot and dry winds and sudden thunderstorms and strong winds. In the south, it is advisable to pay close attention to the top dressing and cultivation of rice, promote the distribution of evils, and seize the sunny days to harvest and dry summer crops.

After Xiaoman, the south of the Yellow River and the middle and lower reaches of the Yangtze River began to experience high temperature weather of more than 35 years, and the relevant departments and units should pay attention to the work of preventing heat stroke. Beware of disasters in the "small full" season.

In 2013, the time of Xiaoman is 05:09:30 on May 21, and Xiaoman is one of the 24 solar terms, the second solar term of summer. The meaning is that the grains of summer ripening crops are beginning to fill full, but they are not yet ripe, but they are only small and full, not yet full.

Year of the Horse] Xiaoman.

2022 Xiaoman time on May 21, 9:22:25 a.m., the twenty-first day of the fourth lunar month. Luo Shuwei, a historian and researcher at the Tianjin Academy of Social Sciences, said that May 20 or 21 of the Gregorian calendar every year is the beginning of the Xiaoman solar term, which is the eighth solar term among the 24 solar terms and the second solar term in summer.

Characteristics of the small full solar termDuring the Xiaoman solar term, there will generally be a lot of rainfall and a lot of rainfall in the southern part of China. Due to the active warm and humid airflow from the south, and the cold air from the north to the south converge in South China at the junction of the yellow and red mountains, there is often a continuous and widespread heavy precipitation in South China, resulting in heavy rain or extremely heavy rain, just like the folk proverb that the clouds are small and the rivers are gradually full.

If there is less rain at this stage, it may be that the subtropical high pressure in the Pacific Ocean is weaker and the location is southerly, which means that it is the Huangmei season. During the small full solar term in the north, there is little or no rainfall, during which the temperature rises rapidly, and the temperature difference with the south is further reduced.

Twenty-four solar terms.

Most of them can be as the name suggests, but Xiaoman is a little puzzling.

It turns out that Xiaoman refers to the filling of wheat and other summer crops when the grain is ripe, and the grains begin to be full.

Sichuan basin. The agricultural proverb gives Xiaoman a new meaning: "Xiaoman is dissatisfied, and he thinks about it"; "Xiaoman is dissatisfied, and he doesn't care."

The word "full" is used to describe the surplus and shortage of rainwater, and it is pointed out that if the field is not full of water, it may cause the field to dry up and crack, and even rice cannot be planted when the mango is planted.

Because "Xiaoman is planting seedlings in the beginning of summer" and "seedlings are running to Xiaomangu and running in autumn", Xiaoman is the season suitable for rice planting.

Whether the summer drought in the basin is severe or not is directly related to the amount of rice planting area. The sooner or later of planting is closely related to the yield of rice.

In the central and western parts of the basin, there are often dry winters and dry springs, and heavy rains come later, in some years until June, and even as late as July.

In addition, the perennial small full solar term.

The rainfall is not much, the average is only about 40 mm, and the natural rainfall cannot meet the water demand for seedlings, which makes the summer drought in the central part of the basin where water is scarce more serious.

Xiaoman is a day between May 20 and 22 of the Gregorian calendar every year.

Xiaoman, the eighth of the 24 solar terms, is also the second solar term of summer. The sun reaches 60° of ecliptic longitude and is celebrated on May 20 to 22 of the Gregorian calendar every year. For example, the small man in 2023 is May 21, and the small man in 2024 is May 20.

The name of Xiaoman has two meanings. First, it is related to climate precipitation. During the Xiaoman solar term, heavy rainfall in the south began to increase, and precipitation was frequent; As the folk proverb goes, "small full and small full, the rivers are gradually full".

The "full" in Xiaoman refers to the surplus of rain. Second, it is related to agricultural wheat. In the northern region, there is little or no rain during the Xiaoman solar term, and this "full" does not refer to precipitation, but to the fullness of wheat.

Climate change in the small full season

During the Xiaoman solar term, southern China generally receives a lot of rainfall and heavy rainfall; The warm and humid airflow from the ocean is active, intersecting with the cold air from the north and south, and there is often a continuous and widespread strong and heavy precipitation in South China, resulting in heavy rain or extremely heavy rainfall. If there is less rain at this stage, it may be that the subtropical high pressure in the Pacific Ocean is weaker and the location is southerly, which means that it is the Huangmei season.

The Xiaoman solar term is often the period with the longest sunshine time among the 24 solar terms in the northern region. It is much easier to heat the dry air in the north than it is to heat the humid air in the south, so when it is small, the temperature of the air in some places in the north can easily rise very quickly, and the temperature difference with the south Songga side is further reduced.
