Introduction: We can't live without many things, such as solar terms, such as traditional festivals, and various interpretations of the zodiac fortune. In our daily life, these things formally accompany us through spring, summer, autumn and winter. The solar term time is different every year, so when is the solar term in 221?

A detailed analysis of solar terms

Twenty-four solar terms refer to 24 specific festivals in the solar calendar (trunk calendar) that indicate seasonal changes, which are formulated according to the position changes of the earth on the ecliptic (that is, the earth's orbit around the sun), and each one corresponds to a certain position that the earth reaches every 15 degrees on the ecliptic. Twenty-four solar terms are a knowledge system formed in ancient times by observing the annual movement of the sun and recognizing the changing laws of seasons, climate and phenology in a year.

Twenty-four solar terms divide the annual movement track of the sun into 24 equal parts, and each equal part is a solar term, starting from the beginning of spring, ending in severe cold and repeating. Each solar term represents the different changes of climate, phenology and time. The lunar calendar in China is a combination of yin and yang, which is based on the sun and the moon's movement, so adding 24 solar terms can better reflect the cycle of the sun's movement.

Agricultural Songs of the Twenty-four Solar Terms

beginning of spring: Starting from spring, sowing in spring, preparing for ploughing, starting early, making a year's plan in spring, and creating high and excellent agricultural production.

rain: rain and spring rain are as expensive as oil, which can prevent soil moisture from flowing, accumulate more fertilizer and thresh more grain, and select fine varieties to win a bumper harvest.

Sting: Sting in warm weather, the hibernating insects wake up, the winter wheat is suppressed to conserve moisture, and the cultivated land is raked and planted with spring wheat.

vernal equinox: there is more wind and less rain in the vernal equinox, when the land thaws, the spring tide begins, the rice fields are leveled and turned over early, and the winter wheat turns green and watered.

Qingming: The grass is green in Qingming Spring, when it is a good time to plant melons and beans, plant trees and plant beets, and raise rice seedlings.

Grain Rain: The snow and frost have not broken in Grain Rain, so don't delay sowing miscellaneous grains. When the family swallow comes back, it will drip water, and the nursery branches will be connected to the orchard.

long summer: The wheat seedlings in long summer are increasing day by day. Rice seedlings should be planted in flat fields, and soil moisture should be protected by intertillage weeding, and windproof in greenhouses should be well managed.

Xiaoman: Xiaoman is mild and spring-like, preventing aphids, wheat stalks and flies, dressing fertilizer in paddy fields to promote evil, and catching wool and shearing to prevent cold wind.

Miscanthus species: Miscanthus species have little rain and high temperature, and maize seedlings are interplanted and fixed, buckwheat in millet valley grabs the seeds for moisture, and weeding in paddy field is diligent.

summer solstice: the hail is fierce at the beginning of the summer solstice, and the seeds are selected by removing impurities, eliminating hail and increasing rain, and the corn is topdressing to prevent armyworm.

light summer: when the light summer comes into the dog days, Longkou grabs food and time, and cultivates the soil in the middle of rice, so it is not easy to prevent rain and fire.

great summer: the heavy heat and rainstorm increase in great summer, multiple cropping of autumn vegetables is tight for flood control, rice blast is predicted, and seedlings are protected against low temperature in deep water.

beginning of autumn: It rains at the beginning of autumn in beginning of autumn, so as to prevent and control corn borer as early as possible, turn deep soil into gold, and pick tree cores by bud grafting in nursery.

Summer treatment: the summer treatment is full of beautiful autumn colors, the main beet should be watered, the grain and vegetables should be managed frequently in the later stage, and the winter wheat should be prepared for seed fertilizer.

White dew: White dew is cold at night and hot during the day. It is a good season to sow winter wheat, harvest sunflowers in the rice field, and pick early-maturing apples.

autumnal equinox: it is getting colder in the autumn rain, the rice is yellow and fruity, and the autumn harvest is busy, and the grain is threshed and handed over to the public, and the mountain area is protected from frost and weather.

cold dew: cold dew grass withers and wild geese fly south, potato beets are busy to be recovered, radish and cabbage are good, and straw is returned to the field for fertilization in autumn.

first frost: It is freezing and frosting in first frost. Pay close attention to the soil moisture in autumn, irrigate winter water in frozen days, thresh and dry the grain to repair the granary.

beginning of winter: In beginning of winter, the frozen ground disappears in the daytime, the sheep and livestock pens are firmly repaired, the fields are prepared and the channels are repaired, and the farmland construction reaches a climax.

light snow: the first snow floats in the light snow field, and the young trees and grapes are quickly buried. Use winter fallow to accumulate fertilizer, and the crops are not fat.

heavy snow: heavy snow and wax snow bode well for a bumper year, and diversified management creates high yield, so timely raking can protect soil moisture and accumulate more fertilizers to find fertilizer sources.

winter solstice: the winter solstice is very cold for several nine days. Sheep and livestock should be protected from the cold, and they should take part in night technical schools. It depends on scientific research to increase production and harvest.

slight cold: slight cold enters for three or nine days, celebrates New Year's Day with a bumper harvest, attends training classes every season, and constantly sums up new experiences.

great cold: although the great cold is cold and farmers are happy, the policy of enriching the people can't be praised, and the production contract will continue to work, and they will be happy for the next year.
