The temperature is getting warmer, the weather is changeable and rainy. In spring, on April 4th or 5th every year, the sun reaches longitude 15. The first and second solar terms after the vernal equinox sweep graves in Grain Rain. Custom foods such as Artemisia cake, green ball, prickly heat, fertilizer and water management of Qingming snail farming activities, pest control, nourishing health, protecting liver and nourishing lung are waiting for tung flowers to bloom; The vole became a quail; Rainbow begins to see the March Festival in 24 solar terms.

"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 pure and bright, so it is called Qingming."

Tong Shihua. Tung, wood name. There are three kinds: the flashy name is Bai Tong, and the so-called elegant Rongtongmu is also; Those green and strong ones are called Wu Tong, and one is called Qingtong. Huainanzi said that Wu Tong had a broken angle; Born in the mountains, there are older children, and those who have oil are called tung trees. Mao Shi said that they were not born in the mountains. The man who started China today is Bai Tonger.

The sound of voles turning into owls. According to Er Ya, it was noted that flying squirrels were as big as mice, with a rabbit-like head, hairy tail and bluish yellow. Fortunately, it eats millet beans in the field and is called vole. It is said in Compendium of Materia Medica and Su Wen that owls and quails are as small as pigeons. Er ya Shi bird: bird, mother. Guo Note: Also, Qingzhou people call it the harrier mother. Bao said: rat, yin; Pelican, Yang; Yang is strong and becomes scorpion, while Yin is covered by Yang.

The rainbow began to see the sound. Rainbow, rainbow, what is poetry? You can't understand this voice. 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 the sun meets the rain, it suddenly becomes a quality. If yin and yang are incompatible, heaven and earth will be obscene. Rainbow is male, red and white, and female, blue and white, but both words come from insects. Shuowen said: Like it? The slug-shaped book also says: When you taste the rainbow and enter the stream to drink water, its head is like a donkey. I'm afraid there is such a thing in the world, but the rainbow spirit seems to be borrowed.

Qingming Festival

Qingming Festival

Tomb-Sweeping Day gas point: Dou refers to B; The solar calendar 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 period from winter solstice to winter solstice of the following year 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 land presents a quiet scene in spring.

During the Qingming period, the average daily temperature in most parts of the country has risen to above 12℃ except the northeast and northwest regions. From north to south to the inside and outside of the Great Wall, there are busy scenes of spring ploughing everywhere. "In the Qingming Festival, the wheat grows for three days", the wheat in the south 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, early and middle rice in the south of the Yangtze River is in a suitable season for mass sowing, so we should seize the opportunity, seize the sunny day and sow early. 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 tomorrow's tea, there will be two buds", and the new buds of tea trees will grow vigorously, so attention should be paid to pest control; Famous tea producing areas are mined one after another, and strict scientific mining is needed to ensure the yield and quality.
