What are the three seasons of Jingzhe and what are their climate characteristics?

What are the three phases of the Awakening of Insects

"In the first phase, peaches begin to bloom; in the second phase, Canggeng (orioles) sing; in the third phase, eagles turn into doves "It describes that it is mid-spring, when peach blossoms are red, pear blossoms are white, orioles are chirping, and swallows are flying. According to the general climate rules, the weather in various places has begun to get warmer around the time of the Waking of Insects, with more rain and spring plowing has begun in most areas. When various insects hibernating in the soil are awakened, the eggs that have spent the winter will also begin to hatch. It can be seen that the Waking of Insects is a solar term that reflects natural phenological phenomena.

Climatic characteristics of the Waking of Insects season

"When spring thunders, all things grow." The Waking of Insects season coincides with the great "nine-nine" sunny days, when the temperature rises and the rain increases. Except for the winter scenes that are still covered in silver makeup in the northeast and northwest, the average temperature in most areas of our country has risen above 0℃. The average daily temperature in North China is 3-6℃, in the areas along the Yangtze River and south of the Yangtze River, it is above 8℃, while in the southwest The temperature in southern China has reached 10-15℃, and it has already been a happy spring.

"Spring thunder shocks hundreds of insects." Warm climate conditions are conducive to the occurrence and spread of various diseases and insect pests, and field weeds have also sprouted one after another. Pest and disease control, cultivating and weeding should be carried out in a timely manner. "When peach blossoms bloom, swine fever comes." The epidemic prevention of poultry and livestock should also attract attention. At this time, the temperature rose rapidly, and spring thunder began to appear in most areas of the Yangtze River Basin.

The importance of the Jingzhe solar term

Entering March, there are two solar terms: "Jingzhe" and "Spring Equinox", and the "Jingzhe" solar term is important in the busy farming period. It is of considerable significance. The working people of our country have attached great importance to the Jingzhe solar term since ancient times and regard it as the day when spring plowing begins. There is a poem in the Tang Dynasty that goes: "A light rain brings new flowers, and a thunder starts to wake up the insects. The fields are idle for a few days, and farming begins." Winter wheat in North China begins to turn green and grow, and the soil is still freezing and thawing alternately. Timely harrowing is an important measure to reduce water evaporation. "If you don't rake the ground when you wake up, it's like steaming steamed buns that have run out of steam." This is a valuable experience of the local people in preventing drought and preserving moisture.
