Introduction to Lixia solar term
As the name implies, Lixia refers to the beginning of summer. However, different places have different temperatures, and the time of summer is actually not the same. According to the standard of climatology that the five-day average temperature is higher than 22 ℃ in summer, the southern part of Sichuan Basin has just entered into summer before and after the beginning of summer; the temperature of the rest of the basin is about 20 ℃, and it is still in the late spring season of 'no one asked to drop flowers outside the door, green shade ran all over the world'; and the low altitude River Valley in Southwest Sichuan felt hot in summer as early as the middle of April, when the temperature reached over 24 ℃, it can be called Summer inflammation Inflammation. "Yiwei" has the theory of "electricity seeing" in Lixia. But for Sichuan, even in the northwest of the basin where the first thunderstorm is the latest, the annual thunderstorm started in the first and middle of April, and it is not necessary to wait until the beginning of summer. After the beginning of summer, it is the key period of water demand for large-scale planting of rice in the basin. The early and late arrival of heavy rain and the amount of rainfall are closely related to agricultural production. At this time, if there is no heavy rain, those fields without irrigation will not be able to rake pears and plant seedlings. According to the statistics of climate data, the average starting period of heavy rain for many years is in the middle and last ten days of April in the east of the basin, in the middle and last ten days of may in the middle and the west of the basin, and in the last ten days of may in the West. In May, the rainfall basin is 100-200mm in the southeast and 75-100m in the northwest. In the West and middle part of the basin, the heavy rain started late, and the rainfall was less, so there was often a summer drought outcrop. During this period, when harvesting spring crops and planting spring crops in the basin, we should pay special attention to the influence of changeable weather. Harvest in time in sunny days, planting in rainy days, even in rainy days, we should be on guard against sprouting and mildew of spring harvest, do well in drought resistance and seedling protection, and be on guard against the harm of low temperature below 20 ℃ to early rice.
An inventory of summer customs
Ancient emperors often held sacrificial activities to pray for a good harvest on the day of Lixia, while the folk made "Lixia soup" from lean meat, peas, bamboo shoots and other ingredients to get rid of moisture and health. It can be seen that since ancient times, China has attached great importance to the solar term of summer, and what folk customs have been preserved since its inheritance?
1. Welcome summer ceremony
Summer of Lixia means big. It means that the plants planted in spring have grown up upright. In ancient times, people attached great importance to the etiquette and customs of Lixia. In the old days, on the day of the beginning of summer, the ancient emperor wanted to lead a hundred officials, both civil and military, to the southern suburbs of the capital to welcome the summer and hold a ceremony to welcome the summer. All princes and ministers should wear red dresses and jade plates. Even horses and flags should be red to express their desire for a good harvest and good wishes. In the palace, they also wanted to "set up ice in summer and give it to the Minister of culture and military affairs". Ice was stored last winter and was given to officials by the emperor.
2. Summer rope
In the old days, five colored silk threads were tied to children's wrists in summer, implying that summer sickness could not be prevented by disaster relief and praying. The silk thread was called "summer rope" or "long life thread".
3. Eat summer egg
As the saying goes, "eggs are eaten in the beginning of summer, and summer will not be stopped in the hot days". It is said that since the beginning of summer, the weather has been sunny and warm and gradually hot. Many people, especially children, will feel tired and limp, and their appetite will be gradually reduced, which is called "blocking summer". Nvwa told the people that every summer, the child's chest is hung with cooked chicken, duck and goose eggs to avoid blocking the summer. The children will also fight for eggs in groups.
4. Don't sit on the threshold
In summer, there is also the saying that people should not sit on the threshold. In Anhui Province, ten years of Daoguang's "county records of Taihu Lake", it is recorded: "in summer, take bamboo amaranth as a soup, do not sit on the doorsill, do not sleep in the daytime, that is to say, worry about summer and get tired. 'it's the day when I sit on the threshold. I'm tired and ill in summer. In the 30's "Ningguo County annals", it is recorded that "Lixia". To weigh the weight of the human body, avoid disease, so-called not afraid of summer. It's said that if you sit on the doorsill at the beginning of summer, you will be in low spirits for a year. 'in summer, children should not sit on stone steps. If they do, they should sit on seven steps before all diseases disappear. Don't sit on the floor (threshold), it is said that this day's sitting on the floor will cause pain in the foot bones in summer. If you sit on one floor, you must sit on six more floors to synthesize seven numbers to solve the nightmare.
