The temperature is getting warmer, the weather is changeable and rainy. In the spring of April 4th or 5th every year, the sun reaches longitude 15.

"Huainanzi Astronomical Training": "On the fifteenth day after the vernal equinox, the bucket refers to B, then the Qingming wind will arrive"; The "Qingming wind" in the article is a refreshing and clear wind. At the age of 100, I asked, "When everything grows, it is clean and bright, so it is called Qingming."

Tong Shihua. Tung, wood name. There are three kinds: the flashy one is called Bai Tong, and the so-called Rongtong Muye in Erya; Those green and strong ones are called Wu Tong, and one is called Qingtong. Huainanzi said that Wu Tong had a corner; Born in the mountains, the children are big, and the oily ones are called tung trees. In Mao's poems, those who are not born in the mountains are also called tung trees. The man who started China today is Bai Tonger.

The vole became the cry of an owl. According to Er Ya, a flying squirrel is as big as a mouse, with a rabbit head and a hairy tail that is bluish yellow. Fortunately, it eats millet beans in the field and is called vole. Both the Classic of Materia Medica and Su Wen say that owls and quails are as small as pigeons. Erya Shi Bird: Bird, mother.

The rainbow began to see the sound. Rainbow, rainbow, what is poetry? You can't read the sound. Note: It is the spirit of the intersection of Yin and Yang. Therefore, Confucianism believes that clouds are thin and the sun leaks, and raindrops in the sun make rainbows grow. Now, water makes the sun shine, but if you look at it from your sword, you will feel dizzy. Zhu Xi said: When sunlight meets rain, it suddenly becomes a quality. If yin and yang don't match, heaven and earth will be obscene. Rainbow is male, the colors are red and white, and the colors of female are blue and white, but both words come from insects. "Shuo Wen" said: Like? The slug-shaped book also says: When you taste a rainbow and enter a stream to drink water, its head is like a donkey. I'm afraid there is such a thing in the world, but the rainbow breath seems to be borrowed from it.

Qingming Festival

Qingming Festival

Qingming cavitation: bucket refers to B; The solar meridian is15; Gregorian calendar April 4-6. The "Twenty-four solar terms" were originally determined by the direction of the top of the bucket handle of the Big Dipper. The bucket handle starts from the "female position" and then rotates clockwise. When bucket handle points to the "second position", it is the spirit of Qingming. From the Han Dynasty to the early Qing Dynasty, the solar terms were divided by the "average time method", and the time from winter solstice to the next winter solstice was divided into 24 segments (each segment was 15 days), with winter solstice as the starting point of the "24 solar terms"; Tomb-Sweeping Day Qi is counted from the winter, that is, the first 105 day after winter. The current "24 solar terms" are determined according to the position of the sun on the ecliptic (it has been used since 1645). When the sun meridian reaches 15, it is the Qingming intersection. By the Qingming Festival, the climate in Huangjijiao and its vicinity has been refreshing and warm, and the earth presents the image of spring and tranquility.

During the Qingming period, the average daily temperature in most parts of China has risen to above 65438 02℃ except the northeast and northwest regions. From the north to the south and then to the inside and outside of the Great Wall, there is a busy scene of spring ploughing and preparing for ploughing everywhere. "During the Qingming Festival, the wheat grows for three days". The wheat in the southern part of Huanghuai is about to start heading, the rape has blossomed, and the wheat in the northeast and northwest regions has also entered the jointing stage. In the later stage, we should pay close attention to fertilizer and water management and pest control. Dry farming in the north and early and middle rice in the south of the Yangtze River are in the suitable season for mass sowing, so we should seize the opportunity to sow early in sunny days. The pear blossoms are getting clearer and clearer. At this time, when many kinds of fruit trees enter the flowering stage, attention should be paid to artificial pollination to improve the fruit setting rate. Early rice planting in South China should be cleaned up and fertilized in time. Corn, sorghum and cotton will also be planted everywhere. "Before tea tomorrow, two buds will be born", and the new buds of tea trees are growing vigorously, so we should pay attention to the prevention and control of pests and diseases; Famous tea producing areas should be mined one after another, and strict scientific mining should be carried out to ensure the yield and quality.
