On solar terms

"Twenty-four solar terms" has such a description: everything thunders in February, and thunder means thunder, so it's a sting, and it's a sting and you leave. At this time, there was spring thunder, and the warm breath made the stinger wake up from hibernation and began to move around.

After the fright, the temperature and ground temperature kept rising, the soil melted, and the spring breeze turned into rain. Therefore, since ancient times, farmers in China have recognized that the fright is the beginning of spring ploughing. Farmers have no idle people, and hoes constantly scare and rake the ground, just like agricultural proverbs such as steaming steamed bread and leaving gas vividly illustrate the importance of this solar term.

With the temperature rising and sunshine increasing all over China, spring ploughing gradually started from south to north. In the southeast of South China and the Yangtze River valley, the temperature in the panic period is stable above 65438 02℃ in most years, which is beneficial to the sowing of rice and corn. Low temperature weather below 12℃ occurs in other areas, and blind early sowing is not allowed. Although the temperature rises rapidly, the increase of rainfall is limited. In terms of rice, when the average temperature of the day is stable above 8℃, you can start sowing and seedling raising in dry land.
