Do animals really wake up on the day of fright?

When the solar term comes, it means that hibernating animals will "wake up", and this solar term does not have to come out; Animals only end hibernation when a series of conditions such as temperature meet the requirements. For example, a white snake in Jinshan Temple in Zhenjiang this year did not hibernate at all because it artificially created a relatively high temperature environment. Instead, he shed his skin more than two months in advance (Yangzi Evening News).

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. One of the 24 solar terms. Sting means hiding.

In ancient China, the fright was divided into three stages: "When the peach blossoms bloom; Second, wait for the sound of Cang Geng (Huang Li); Three waiting eagles turned into pigeons. " Described as the season of peach blossom red, plum blossom white, orioles howling and swallows coming, most areas have entered spring ploughing. When all kinds of insects dormant and hibernating in the soil are awakened, eggs will begin to ovulate in winter, so it can be seen that fright is a solar term reflecting natural phenology.

On March 5th and 6th, every year, when the sun reaches 345 degrees, it is "in a daze". Sting means that when the weather gets warmer, the spring thunder begins to sound, awakening the insects that are dormant and hibernating underground. "Twenty-four solar terms" said: "February Festival, everything vibrates, and when it vibrates, it thunders, so it is called thunder. It's an escaped cockroach. Tao Yuanming, a poet in the Jin Dynasty, said in a poem: "In the spring rain, thunder began in the east corner, and everyone was lurking and the grass was comfortable. "In fact, insects can't hear thunder. Spring is back, and the warmer weather is the reason why they end their hibernation and "run away in surprise". In China, the time when the spring thunder begins to ring varies from place to place. On the average for many years, thunder can be heard in southern Yunnan around the end of 1, and the first thunder day in Beijing is in late April. The saying that "thunder begins with you" is consistent with the climate law in Jiangnan.

"Spring thunder rings, everything grows", and it is a fine sunny day in September, with the temperature rising and the rain increasing. In addition to the winter scenes in which the northeast and northwest regions are still covered in white, the average temperature in most parts of China has risen above 0℃, the average daily temperature in North China is 3-6℃, the temperature in the south of the Yangtze River is above 8℃, and the temperature in Southwest China and South China has reached 10- 15℃, which is already a harmonious spring. Therefore, the working people in our country have attached great importance to this solar term since ancient times and regarded it as the beginning of spring ploughing. There is a cloud in the Tang poetry: "A light rain brings new flowers, and a thunder starts. Tian Jia was idle for a few days, and farming began. " Agricultural proverbs also say, "You can't rest in spring ploughing, after the Scare Festival", "Do your best to raise bloom, and farm work will be complete." Winter wheat in North China began to turn green, and the soil was still frozen and thawed alternately. Raking the ground in time is an important measure to reduce water evaporation. "Shocking without harrowing is like steaming steamed bread", which is a valuable experience for local people to fight drought and conserve moisture. Wheat in the south of the Yangtze River has been jointing and rape has begun to blossom. There is a high demand for water and fertilizer, so topdressing should be done in time, and proper irrigation should be done in dry and rainy places. Rain in the south can generally meet the needs of vegetables, wheat and green manure crops in spring, and it is most important to prevent wet damage. As the saying goes, "It's better to dump manure than to plow wheat with three pipes" and "If you want to harvest rapeseed, you must manage plowing diligently". We should continue to do a good job in ditch cleaning and drainage. We should pay close attention to sowing early rice in South China, and at the same time do a good job in cold prevention in rice fields. As the temperature rises, tea trees gradually germinate, so it is necessary to prune and apply "germination accelerating fertilizer" in time to promote more branches and leaves and increase tea yield. Fruit trees such as peaches, pears and apples should be fertilized before flowering.

"Spring thunder scares thousands of insects", and the warm climate conditions are conducive to the occurrence and spread of many diseases and insect pests, and weeds in the fields sprout one after another. It is necessary to do a good job in pest control and intertillage weeding in time. "Peach blossoms come, swine fever comes", and we should also pay attention to the epidemic prevention of poultry and livestock.

The agricultural proverb "When it comes to thorns, the hoe will not stop." By the time of the earthquake, most parts of China had entered the busy season of spring ploughing. Really: the season waits for no one, and every moment is worth a thousand dollars. In most areas, the average temperature of scary solar terms is generally 12℃ to 14℃, which is more than 3℃ higher than rainy solar terms, and it is the solar term with the fastest annual warming. The sunshine time has also increased significantly. However, due to the alternation of cold and warm air, the weather is unstable and the temperature fluctuates greatly. In the Yangtze River valley in the southeast of South China, the temperature in the warning period is stable above 65438 02℃ in most years, which is beneficial to the sowing of rice and corn. The average daily temperature in other areas is lower than 12℃ for more than three consecutive days, so it is not allowed to sow blindly early. Although the temperature rises rapidly, the increase of rainfall is limited. The total rainfall in central and northwest South China is only about 10 mm, and spring drought often begins after winter drought all the year round. At this time, the booting stage of wheat and flowering stage of rape are in a period of high water demand and are sensitive to water demand. Spring drought often becomes an important factor affecting the output of Koharu. Afforestation should also consider this climate feature, plant logistics and water, and strive to improve the survival rate of saplings.

The vibration reflecting natural phenology refers to the sudden movement of spring thunder, which awakens the animals dormant and hibernating in the soil. At this time, the temperature rose rapidly, and spring thunder gradually appeared in most areas of the Yangtze River Basin. In most parts of southern China, the first sound of spring thunder can also be heard in the perennial rain and stormy waves; However, except for a few years, it usually doesn't thunder until Qingming, which is the latest area where thunderstorms start in most parts of southern China.

In the season of fright, the spring is bright and everything is revived. Through careful observation and accumulation of phenological knowledge, it will help to arrange farming activities according to local conditions.
