What are the solar terms and health knowledge in spring?

The six solar terms in spring are: beginning of spring, Rain, Sting, Equinox, Qingming and Grain Rain.

Beginning of Spring

"Stand" means to start. Beginning of spring On February 4th and 5th of each year in the solar calendar, beginning of spring is the first 24 solar terms, which indicates the change of seasons, the severe winter has passed and spring is coming. Due to China's vast territory and complex terrain, not only does spring come to the earth early or late, but it also stays in various places for a long time. She set off from Guangzhou, which is connected with winter and spring, and went north at the end of February at 65438+/kloc-0. In mid-February, she first arrived in Kunming, Yunnan, and then crossed the Yunnan-Guizhou Plateau and entered the Sichuan Basin. In mid-March, she arrived in Wuhan, Hubei, Zhengzhou, Henan and Jinan, Shandong. In early April, she arrived in Beijing and Tianjin, crossed Shanhaiguan to Shenyang outside the Great Wall, and arrived in Harbin in late February. Around May 20th, she can go to Mohe, the farthest place in northern Xinjiang.

As far as China's main farming is concerned, beginning of spring in Northeast China should plough the fields, send manure to accumulate fertilizer, and do a good job in animal epidemic prevention. The North China Plain should actively prepare for spring ploughing and build water conservancy projects. Spring wheat should be prepared and fertilized in northwest China. Due to the high temperature in South China, a comprehensive spring ploughing and sowing work has been carried out at this time. Southwest China should pay close attention to the ploughing and ploughing of early rice seedling fields, and do a good job in the field management of seed selection, seed drying and summer harvest crops.

Beginning of spring is a sensitive period for teenagers to get sick, especially for upper or lower respiratory tract infections, including colds, tonsillitis, bronchitis and pneumonia. How to prevent these diseases? First, teenagers are susceptible people, so try not to go to public places and pay attention to isolation from cold patients. Second, the climate in spring is changeable, so we should pay attention to keep warm and avoid catching a cold. Third, pay attention to the circulation of indoor air, moderately open windows for ventilation, close doors and windows when necessary, and fumigate the air with vinegar. Fourth, pay attention to food hygiene, eat lightly, drink more water, and don't eat or eat less snacks. Fifth, take part in more physical exercises to enhance physical fitness. Sixth, if you are sick, you must go to the hospital for treatment.

Rain Water

It means that it begins to rain and the rainfall gradually increases. It rains around February 18 in Gregorian calendar every year. Rain has two meanings: first, it changes from snowfall to rainfall; Second, since the "rain", the weather has turned warmer, the force of warm and humid airflow in the south has become stronger, and precipitation has increased. After the "rain", the temperature in most parts of China has reached above 0℃, the daily average temperature in Huanghuai Plain is around 3℃, the average temperature in Jiangnan is around 5℃, and the temperature in South China has exceeded 10℃, but the temperature in North China Plain is still below 0℃. Under such a climate background, it began to rain in Huanghuai Plain and its south area, and sometimes it snowed in North China Plain.

In agriculture, as far as the field is concerned, rape and winter wheat generally turn green around the "rain", and the demand for water is relatively high. The precipitation in North China, Northwest China and Huanghuai areas is generally less at this time, which often cannot meet the needs of crops. If there is little rain in early spring, spring irrigation should be carried out in time before and after the "rain". At this time, there is generally more rain in the area south of Huaihe River, so it is necessary to clear ditches and drain water, eliminate water accumulation in farmland, intertillage and weeds, and prevent wet damage and root rot. Seedling raising of double-cropping early rice in South China has started. In order to prevent the harm of cold and hot weather, we should pay attention to the "cold tail and warm head" weather to catch up with sunny sowing, and strive to sow all seedlings at once. The mountainous areas in the northwest plateau are still in the dry season and are prone to fire. In addition, the invasion of cold wave can cause strong cooling and snowstorm, which is extremely harmful to the old, weak and young animals. These are all things that need special attention.

Rainy solar terms are often between the Spring Festival and the Lantern Festival. When people are busy and happy, they should eat moderately and live regularly, and strive for a healthy, happy, safe and peaceful festival. In life, we should change the habit of frying, cooking and steaming a lot of food during festivals and "reheating" it every day. Food should be kept fresh, pay attention to prevent deterioration, and patients with chronic diseases should pay more attention to diet control. For example, in patients with chronic gastritis, improper diet is more likely to aggravate gastric mucosal damage; Patients with chronic cholecystitis or pancreatitis should reduce fat intake; Patients with cardiovascular and cerebrovascular diseases have a light diet; Gout patients should avoid eating seafood and drinking alcohol. In addition, we should also pay attention to good habits such as moderate diet, chewing slowly, low sugar and salt, quitting smoking and limiting alcohol, and paying attention to hygiene.

Awakening of Insects

The sudden movement of spring thunder awakened the animals that were dormant and hibernating in the soil. At this time, the temperature rose rapidly, and the spring thunder gradually sprouted. Every year around March 5 of the Gregorian calendar is a shock. The reason why thunder occasionally occurs before and after the sting is because the earth's temperature rises gradually, the hot air on the ground rises or the hot and humid air in the north moves gradually and frequently. However, the north-south span of our country is large, and thunder can be heard in southern Yunnan in June 5438+065438+ 10, and in Beijing in late April.

The thorn represents the beginning of spring ploughing. Winter wheat in North China began to turn green and needed water badly. Once lack of water will reduce production, so water winter wheat and peas in time. At this time, the soil is still in the alternate state of freezing and thawing, and timely harrowing is an important measure to reduce water loss. Early rice should be sown in time in South China, and at the same time, the cold protection of seedlings should be done well.

During the dormant period, the weather is hot and cold, and the humidity increases. When the respiratory defense function of human body declines, it is easy to be attacked by pathogens and catch a cold, so it is necessary to go to public places with poor ventilation less. Dry immediately after sweating. Eat more nutritious foods such as eggs, fresh fish, tofu, vegetables and fruits.

Spring Equinox

"Minute" means equal share, that is, the length of day and night is equal. Generally on March 20th of the Gregorian calendar every year. After the vernal equinox, the average temperature in most parts of China rose to 10℃, entering the real spring. However, in the process of warming up, due to the invasion of cold air, the temperature often returns to a cold state. This kind of weather with warm spring before and cold spring after is called "cold spring".

Severe late spring cold not only causes rotten seeds, rotten seedlings and dead seedlings of cotton and early rice, but also affects the flowering and pollination of rape and reduces the yield. Therefore, on the one hand, drought resistance is still an important agricultural activity in the vernal equinox; On the other hand, it is necessary to strengthen the defense against freezing injury. Commonly used methods include selecting cold-resistant seeds, reasonable sowing depth of wheat, increasing application of potassium fertilizer, irrigation or spraying, etc.

There is a lot of rain in the spring equinox, and articles are prone to mildew. Meteorological factors such as temperature, air pressure, airflow and humidity are changeable, so many diseases often recur. Keep an open mind and an optimistic mood, and try to avoid being upset. Pay attention to keep warm and cold, and increase or decrease clothes according to climate change, so as to achieve the effects of maintaining human yang, preventing diseases and protecting health. In terms of sleep, you can stay up late and get up early in spring. Often go for a walk outdoors and breathe fresh air. It is advisable to do activities with little exercise at ordinary times. You can take a walk, run and play Tai Ji Chuan at night.

Qingming Festival

Qingming means sunny weather, fresh air, gradual warming and lush vegetation. The Gregorian calendar is Qingming around April 5 every year. During the period of Tomb-Sweeping Day, the average daily temperature in most parts of China rose to 65438 02℃, glaciers thawed, flowers blossomed, and farmers were busy sowing.

When sowing spring crops such as corn and sorghum in the north, we should pay attention to prevent the harm of late frost to wheat and corn. Many plants in South China have entered the flowering stage and need artificial pollination to improve fruit yield. Wheat in the south of Huanghuai has been jointing, so it is necessary to do a good job in fertilizer and water management and pest control in the later stage of wheat. On the one hand, abundant rain is beneficial to the growth of crops, on the other hand, it is necessary to prevent excessive precipitation.

When Tomb-Sweeping Day goes out for a spring outing, it is necessary to prevent flower poison, fatigue and pollen allergy. As the temperature rises, some people quickly take off their heavy winter clothes, but it is warm and cold in sunny weather, and the temperature fluctuates greatly, and it is a little cold in the morning and evening, so it is easy to catch a cold.

Grain Rain

The increase of rainfall is very beneficial to the growth of cereal crops. Grain Rain is around April 20th of the Gregorian calendar every year. It's late spring in Grain Rain. Before and after Grain Rain, the weather turned warmer, frost and snow broke, and rainfall increased. Now is an important season for sowing and unearthed spring crops, and early autumn crops such as sorghum, millet, spring corn and sweet potato are also being sown.

At this time, wheat should pay close attention to fertilization and seedlings should be topdressing. Applying foliar fertilizer once to rape can promote seed hypertrophy. All localities should plant cotton, corn and wheat when the weather is suitable. The picking of spring tea in Grain Rain has entered the peak season, so we should hurry up.

Grain Rain is at the turn of spring and summer, and there are many sandstorms in many places, which are extremely harmful to health. At this time, outdoor activities should be avoided in dusty weather. When going out or working, choose a time when the floating dust is light, and wear a mask or wrap your head with a scarf when going out. Close the living room doors and windows to prevent floating dust from entering the room. Pay attention to diet, drink plenty of water, and eat some foods that can remove lung pollution. Knowledge point twenty-four solar terms

The 24 solar terms are divided according to the position of the sun on the ecliptic. Spring is divided into points, the ecliptic is divided into 24 segments, each segment is 15 degrees, and every time the sun moves 15 degrees, it represents a solar term.

Twenty-four solar terms are a supplementary calendar made by China to guide farming in ancient times. Because the lunar calendar in China is a "lunar calendar", which is based on the sun and the moon, it can't fully reflect the solar cycle. China is an agricultural society, and agriculture needs a strict understanding of the operation of the sun. Farming is carried out entirely according to the sun, so the "twenty-four solar terms" that reflect the solar cycle alone are added to the calendar.

Twenty-four solar terms can reflect the changes of seasons, guide agricultural activities and affect the food, clothing, housing and transportation of thousands of families. Because of China's vast territory and great differences in climate, the 24 solar terms are not suitable for every region, and are mainly applicable to the middle and lower reaches of the Yangtze River and Yellow River.
