When is the vernal equinox? What are the characteristics?

Time gently pushed open the door of spring and awakened the most beautiful season on earth-the vernal equinox. Read the poems of the vernal equinox and feel the beauty of mountain flowers in the eyes of the ancients. Spring is full and spring birds sing.

First, the beauty of the vernal equinox in the eyes of the ancients:

The beauty of the vernal equinox depicted by Ouyang Xiu, a poet in the Song Dynasty, in Sha Xing Ji;

Rainy scenery, vernal equinox weather. Let a hundred flowers blossom. Draw a pair of Liang Xinyan, and the jade cage parrot sleeps alone. Ficus pumila is against the wall, and strawberry moss is all over the floor.

The poet recorded the spring scenery and Chun Yan after the rain with beautiful poems. This poem not only describes the pairing of flowers and Chun Yan, but also shows the characteristics of humid air at the vernal equinox. The humid air covered the wall with moss, and at first glance it was full of beautiful spring scenery.

Now, if you want to see such a beautiful spring scene in Ouyang Xiu's works, you can only see it in a small park that specializes in planting many flowers, but the artificial sculpture is definitely not as beautiful as the ancient natural formation. Now think about it, how enviable it was to see flowers blooming everywhere in ancient times.

The vernal equinox in Song Dynasty poet Xu Xuan's work "Four Wonders Awakening" is like this:

At the spring equinox, the rain falls lightly, and the slanting wind on the Liu 'an sends guests home.

The northern season is late, and I knew there was green waist fat.

In the poet Xu Xuan's works, the spring rain is so gentle, and the lush willows all reveal a feeling of spring, but the characteristics of the vernal equinox in the northern country where the poet is located have not been fully highlighted, so the enviable southern grass is growing.

This poem shows the scenery and climate characteristics of the northern vernal equinox. Willow trees are particularly lush, and spring rain is not that kind of heavy rain. Moreover, the poet also popularized the little knowledge of the difference between the spring equinox and the seasonal difference between the north and the south, which now seems very intimate.

Yuan Zhen, a poet in the Tang Dynasty, described the vernal equinox in his poem "Poems on February 24th":

Two qi don't fight, spring equinox rain. Come to the movies when it rains, but the clouds are louder than thunder.

The mountains are sky blue and the flowers in the forest are bright. There is a mysterious bird in the beam, and I want to do something good.

The poet comprehensively described the scenery on the day of the vernal equinox, whether it was the spring rain and thunder in the sky, or the green trees, spring flowers and Chun Yan on the ground, it was so beautiful.

If you read this poem carefully, you will find that the poet's knowledge is very rich, because it not only describes the scenery in spring, but also tells us something about the climate of the vernal equinox. For example, the "secondary air" at the beginning is the cold air mass and heating in the current climate. The author mentioned that cold and warm air masses mainly led to the appearance of spring rain later. Because the rain and thunder in spring are formed by the collision of meteorological cold air mass and warm air.

The second half describes the spring scenery after the rain. The mountains are green, connected with the sky, and the flowers in the forest are connected with the sun, which is particularly bright. Swallows are whispering among the beams. After reading this poem, I really lamented the wisdom of the ancients. In the case that we still have a little knowledge of the climate, the ancients can already regard it as a poem and write it beautifully.

Second, how did the ancients celebrate the vernal equinox:

Quan Deyu, a poet in the Tang Dynasty, described his time at the vernal equinox in his book "227 Society and the Vernal Equinox":

Sitting with the curtains open on a sunny day, the scenery is everywhere. Look at flowers and poems, and worry less about drunkards.

Social Day, Swallow Qi Fei, Vernal Equinox Warbler. I can't see what I'm thinking, but I still feel it.

On the day of the vernal equinox, the poet Quan Deyu sat at the window to enjoy the spring scenery, and then drank a glass of wine.

In the spring equinox, everywhere is full of vitality, swallows are also in pairs, and birds are also singing their voices. There are always some people who think that their lonely life is incompatible with spring. Not only the ancients had such an idea, but we modern people who live outside, like poets, always feel homesick when faced with beautiful scenery.

Zhao Changqing, a poet in the Song Dynasty, described his vernal equinox in "Dianjiang Lip" like this:

It's warm and cold at first, and the flower viewing weather will be half in spring. Liu Yaojin asks friends, and warblers call each other.

Jade wrist moth eyebrow, eye frequency. Yu Shan was persuaded by a soft voice. When you're drunk, you have to fight each other.

At the vernal equinox, the poet Zhao Changqing felt that the flower viewing season was over half, so he missed it if he didn't cherish it, so he quickly enjoyed the spring scenery, willows swaying, orioles singing and toasting. I'm not drunk at such a wonderful time.

What poets do is what we should do in the face of the beautiful scenery of the vernal equinox, cherish the spring scenery in front of us, drink and chat with friends we haven't met for a long time, put aside all work and troubles, and integrate into the beautiful scenery to be a relaxed self.

Cen Can, the author of the Tang Dynasty, chose to enjoy spring with friends at the vernal equinox:

Guo Nan Chu Shi's house, Luo Qunfeng is outside the door. Victory almost led to the other side, and Chunhua is now strong. There is pulp in the bamboo of mountain kitchen, and there is pulp between wild vines. Count a few wine clouds and several thousand roller blinds.

States and counties should be careless at night. The grass ribbon is facing the rain, and the sound of the beach is also a night bell. Love is plain and secular, so why be old? I had an appointment under the forest, and I turned to the outside world.

Cen Can added a friend to visit a friend's mansion. My friend's mansion faces the mountains. Spring is just right, the spring water is endless, the grass is covered with morning rain, and the sound of running water on the beach is mixed with distant bells. Life in spring is really leisurely.

Cen Can, a poet, is as unwilling to live up to such beautiful scenery as Zhao Changqing, while Cen Can prefers to treat spring gently and feel the infinite beauty of spring with appreciation. It really makes us envy the fast pace.

Third, the vernal equinox is not only a good time to enjoy flowers and travel, but also an important time for spring ploughing:

Song Wan, a poet in the Qing Dynasty, described spring ploughing in "A Family of Spring" like this:

Noda yellowbird is a group of its own, and the old story of the mountain is old.

Niu Jiao women got up in the middle of the night, and planting trees in the Ming Dynasty was the vernal equinox.

This poem mainly writes that spring is the season of flowers and birds, and it is also the season of sowing. In the countryside, there are busy people everywhere.

In addition to the beautiful scenery in the spring equinox, there are naturally some busy figures. Old farmers in the mountains should take advantage of the vernal equinox to plant trees quickly, just as the proverb says: "Only when there are idyllic rice and wheat fragrance in agricultural areas can there be endless vitality on earth." What is sown in spring, what is harvested in autumn.

In order to better understand these ancient poems, here are some tips about the vernal equinox:

The vernal equinox is one of the 24 solar terms and the fourth solar term in spring. On the vernal equinox, the sun shines directly on the equator, and the time between day and night is equal all over the earth. Therefore, the ancient vernal equinox and autumnal equinox are also called "equinox", and there is a folk proverb that "vernal equinox and autumnal equinox are equally divided day and night". After the vernal equinox, the climate is mild, rainy and sunny.

After the vernal equinox, the overwintering crops in most parts of China entered the spring growth stage. As the saying goes, "The spring equinox begins with wheat, and the fat and water should follow". A spring rain was warm. After the spring rain, I was busy plowing. The busy farming season in spring is about to begin, and spring management, spring ploughing and spring planting are about to enter a busy stage. After the vernal equinox, overwintering crops enter the growth period, so field management should be strengthened. Because the temperature rises rapidly and the water demand is relatively large, farmers should strengthen water storage and moisture conservation.
