Climatic characteristics of Qingming Festival

When Qingming comes, the climate in South China is warm and spring is in full swing. However, around the Qingming Festival, cold air still invades from time to time, even causing the daily average temperature to fall below 12°C for more than three consecutive days, causing rotten middle rice seedlings and dead early rice seedlings. Therefore, rice sowing and planting should avoid the warm tail and cold head. In the northwest plateau, livestock have been affected by the harsh winter and insufficient forage, and their resistance is weak. It is necessary to strictly guard against the harm to old, weak and young livestock caused by the strong cooling weather after the beginning of spring.

"It rains heavily during the Qingming Festival" is a portrayal of the spring rain in the south of the Yangtze River by Du Mu, a famous poet in the Tang Dynasty. But for some areas, this is not the case. In particular, western South China is often in the spring drought period. The rainfall in early April is generally only 10 to 20 mm, less than half of that in the Jiangnan area. Although eastern South China has more spring rain, the rainfall in early April is generally only 20 to 40 mm. Natural precipitation It is not enough to meet the needs of agricultural production and must be replenished by water storage in previous years. In addition, May and June are the months with the most hailstorms of the year, so prevention against hail disasters should be strengthened.

During the Qingming Festival, except for the northeastern and northwest regions, the daily average temperature in most parts of China has risen to above 12°C. There is a busy scene of spring plowing from north to south of the Yangtze River to inside and outside the Great Wall. "During the Qingming Festival, wheat grows for three seasons." Wheat in the south of the Huanghuai region is about to boot, rapeseed has bloomed, and wheat in the northeast and northwest has also entered the jointing stage. We should pay close attention to the later fertilizer and water management and disease and insect pest control work.

Dry farming in the north and early and mid-season rice in the south of the Yangtze River have entered the suitable season for large-scale sowing. We must seize the opportunity to sow early when the weather is clear. "The wind blows in the pear blossoms during the Qingming Festival". At this time, various fruit trees enter the flowering period. Attention should be paid to artificial assisted pollination to increase the fruit setting rate. The planting of early rice in South China is almost finished, and fertilizing the fields should be carried out in a timely manner. Corn, sorghum, and cotton will also be sown in various places. "Mingqian tea, two buds", the new buds of the tea tree are growing vigorously, so we must pay attention to the prevention and control of diseases and pests; famous tea production areas have been gradually exploited, and they should be strictly and scientifically harvested to ensure yield and quality. The phenological characteristics of the Qingming solar term:

First phase: Tongshihua

When Qingming comes, the white tung flowers bloom, and the fragrance is pleasant. In spring, everything revives, and during the Qingming Festival, the yang energy becomes stronger and all kinds of flowers bloom.

In the minds of the ancients, the day when the white tung flowers bloom is slightly later, which happens to be during the Qingming Festival, so this is used as a sign of the arrival of the Qingming Festival. On Qingming Festival, walking in nature, watching various flowers slowly withering, the beauty of the ground turning into mud in an instant, makes people sad. However, on another slope, I suddenly saw a tall white tung tree standing in a small farmyard under the thin white clouds. The tree was full of purple and white bell-like flowers, filling the field with fragrance. Surprise and shock! This is the power of flowers and the moving part of life. No wonder the ancients had a special liking for this flower.

The flower letter represented by the first candidate: Tung blossom.

Second period: The field mouse turns into a quail

The field mouse hides in its cave due to the increasing heat of the sun, while the birds that love the sun begin to come out and move around.

The field mouse is the most yin thing, and the bird is the most yang thing. This phrase means that the Yin energy is latent and the Yang energy is gradually increasing. It can be seen that the scene of the grass growing and the orioles flying in the spring is in compliance with the changes of nature.

The flower message of the second candidate: wheat flowers.

Three Weathers: The Rainbow Begins to See

It rains a lot during the Qingming Festival, so the rainbow appears.

In the beautiful spring, only with the washing of rain and the lush green leaves of plants covering the bare soil and absorbing dust can a beautiful rainbow appear in the sky after the rain.
