What is the significance of Jing Ke and White House in agricultural production?

Surprisingly, it was called "Qi Zhe" in ancient times, which was the third of the 24 solar terms and the beginning of the official calendar of Uzuki. The time point is between March 5 and 6 in Gregorian calendar, when the sun reaches 345 longitude. "Twenty-four solar terms": "February Festival ... everything is shocked and thunderous, so it is called a thorn. It's a leaving thorn. "

The time of panic is correct between March 5 and 6 of the Gregorian calendar. Some people used to say that "the time is around the first day of the second lunar month", which is wrong. The dates of lunar and solar calendars are quite different.

At this time, the weather is getting warmer and there is gradually spring thunder. Animals hide in the soil in winter and don't drink or eat, which is called "sting". "Thunder" is the day when God wakes animals with thunder. At this time, most parts of China have entered the spring ploughing season.

Important significance

This solar term is of great significance in busy farming. Since ancient times, the working people in our country have attached great importance to the solar term of fright and regarded it as the day when spring ploughing began. There is a saying in Tang poetry: "A light rain brings new flowers, and a thunder begins." Tian Jia had a few days off, so he began to farm. Agricultural proverbs also say, "Spring ploughing can't rest, after the Scare Festival", "Do your best to raise bloom, and farm work will come together." 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, "wheat should be ploughed in three parts, and matches are like throwing dung", and "if you want to harvest rapeseed, you must be diligent in ploughing". 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.

Millennium-one of the 24 solar terms

The Millennium is the fifteenth of the twenty-four solar terms, and it is also the beginning of the application of the dry calendar and January. The time is from September 7th to 9th every year in Gregorian calendar, when the sun reaches 165 degrees.

"Twenty-four solar terms" said: "August Festival ... Yin Qi is getting heavier and heavier, white and revealing." As the weather gets colder and colder, you will find many dewdrops on the ground and leaves in the morning, which is named after the water vapor condenses on them at night. The ancients used four seasons with five elements, and autumn was golden and golden white, so white was used to describe autumn dew. The Millennium actually indicates that the weather is getting cold.

Current agriculture

Farming: Cold air is becoming more and more active this season, and low temperature weather often occurs in autumn, which affects heading and flowering of late rice. It is necessary to guard against low temperature chilling injury and pests and diseases. When cold air invades, water can be used to keep warm, and water more than two inches before low temperature can raise the temperature by 1~2℃. When the temperature is low, shallow water can be poured in sunny days and nights; Pour thick water on rainy days; The weather is generally dry, wet and wet, mainly wet. This solar term gradually fades away, the autumn is crisp, the jade dew is cool, and the osmanthus fragrance is fragrant, which is the golden tourist season. "White dew" is at the turn of summer and autumn, and the temperature changes greatly from day to day. "White dew does not show", so the old, weak, sick and disabled should pay more attention to changing clothes in time to prevent catching cold.
