Specific analysis of solar terms
Twenty-four solar terms refer to 24 specific solar terms in the solar calendar (dry calendar), which are formulated according to the position change of the earth on the ecliptic (that is, the orbit of the earth around the sun), and each solar term corresponds to a certain position that the earth reaches every time it runs 15 on the ecliptic. Twenty-four solar terms are a knowledge system formed in ancient times by observing the movement of the sun for a year and understanding the changing laws of the four seasons, climate and phenology in a year.
Twenty-four solar terms divide the sun's annual trajectory into 24 equal parts, and each equal part is a solar term, starting from beginning of spring and ending with severe cold. Each solar term represents different changes in climate, phenology and time. China's lunar calendar is a combination of yin and yang, which is based on the movement of the sun and the moon, so adding 24 solar terms can better reflect the cycle of the sun's movement.
24 solar terms, climate and agricultural songs
Beginning of spring: From the beginning of spring, we should fight for six or nine heads, sow in spring and prepare for farming early. A year's plan lies in spring, and agricultural production will be high and excellent.
Rain: Rain and spring rain are as expensive as oil, which can prevent soil moisture from flowing, accumulate more fertilizer and thresh more, select fine varieties and win a bumper harvest.
Scare: The weather is warm, the air is open, hibernating insects wake up, and winter wheat is inhibited to conserve moisture, and spring wheat is raked in the cultivated land.
Vernal equinox: the spring equinox is windy and rainy, the land thaws and the spring tide begins, the rice fields are leveled and plowed early, and the winter wheat turns green and watered.
Qingming: Qingming spring grass is green, which is a good time to plant melons, beans, beets and seedlings.
Grain Rain: The snow and frost have not broken in Grain Rain, so don't delay sowing miscellaneous grains. The swallow drops when it comes back, and the branches of the nursery are connected to the orchard.
Long summer: In long summer, wheat seedlings grow taller and taller, rice seedlings should be planted on the flat ground, intertillage weeding should protect soil moisture, and the greenhouse should be windproof.
Xiaoman: Xiaoman is as mild as spring, preventing aphids, wheat stalks and flies, fertilizing rice fields to promote evil, and catching and shearing wool to prevent cold wind.
Miscanthus species: Miscanthus species have less rain and high temperature, corn seedling interplanting is fixed, buckwheat seeds grab water, and weeding in paddy field.
Summer solstice: Hail is fierce in summer solstice and early summer. Seed is selected by removing impurities, eliminating hail and increasing rainfall, and dry hot wind is used to prevent corn from sticking.
Slight summer heat: when entering the dog days, Longkou grabs food and grabs time, and cultivates rice and soil, which is not easy to prevent rain and fire.
Big summer: the summer heat and heavy rain increase, autumn vegetable multiple cropping flood control is tense, rice blast prediction, deep water low temperature seedling protection.
Beginning of autumn: Autumn rain began to fall in beginning of autumn, in order to prevent corn borer as soon as possible, turn deep soil into gold, and sprout trees in the nursery.
Summer vacation: In the crisp summer vacation in autumn, emerald beets should be watered, grain and vegetables should be carefully managed in the later period, and winter wheat should be prepared for planting fertilizer.
White dew: White dew is cold at night and hot during the day. This is a good season for sowing winter wheat, harvesting sunflowers in sun-dried rice fields and picking early-maturing apples.
Autumnal equinox: The autumn rain is getting colder, the rice tastes yellow and fruity, the autumn harvest is busy, the grain is threshed and handed over to the public, and the mountain area is frost-proof and listening to the weather.
Cold dew: cold dew grass withers and geese fly south, potatoes and beets are busy recovering, radishes and cabbages are good, and straws are returned to fields for fertilization in autumn.
First frost: the first frost is frozen frost. In autumn, we should pay close attention to storing soil moisture. In freezing days, we should irrigate winter water, thresh and dry grain, and repair granaries.
Beginning of winter: In beginning of winter, the frozen soil disappeared during the day, the sheepfolds and livestock pens were repaired firmly, the fields were leveled, the channels were repaired, and the farmland construction reached a climax.
Xiaoxue: The first snow was sealed in the Xiaoxue field. Young trees and grapes were buried quickly, and the crops were not fat in winter.
Heavy snow: heavy snow and wax snow indicate a good year, and diversification creates high yield. During harrowing, soil moisture is maintained, more fertilizer is accumulated, and fertilizer sources are sought.
Winter solstice: Winter solstice lasts nine days. Sheep and livestock should be cold-proof, and it is very important to attend night classes. Increasing production and harvesting depends on scientific research.
Slight cold: Slight cold enters three or nine days, makes a fortune for the New Year, attends training classes in the current season, and constantly sums up new experiences.
Great cold: Although it is cold, farmers are happy, but the policy of enriching the people is full of praise, and they will be happy in the coming year if the production contract continues.
