Why are spring rains as expensive as oil? The master gave me some advice?

Interpretation: Spring rain is as expensive as oil. Describe the spring rain as precious.

Source: Song Shi Daoyuan's "Jingde Chuan Lantern Record" Volume 1: "A drop of spring rain is as smooth as oil. Ming Xie Jin's "Spring Rain": "The spring rain is as expensive as oil, it flows all over the streets, slips and falls to solve the bachelor's degree, and laughs at a herd of cattle." ”

Spring drought is more serious in North China, and spring rainfall accounts for 10-15 of the annual precipitation, and some places are less than 10. Spring follows the two rainy seasons of autumn and winter, coupled with the rapid rise of temperature in spring, many windy days and strong evaporation, which is often prone to continuous drought. At the same time, at this time, it is the period when the overwintering crops are back to the milk maturity period, which requires more water, and the sowing of corn and cotton into seedlings also requires sufficient water, so the spring drought is prominent.

At this time, if there is rain to come, it is naturally very precious, so there is a saying that "spring rain is as expensive as oil". The reason is that at this time, the summer fashion stays in the Lingnan area, and the rainy season has not yet arrived.

Oh hehe, I think so:

Because spring is the season of recovery of all things, plants and plant seedlings sprout and grow the fastest by the moisture of the continuous spring rain (if it is heavy rain and torrential rain in summer, the seedlings are not killed by the raindrops but also rotten by the roots flooded by the rain), and the spring is a gentle light rain and the amount of rain is not much (there seem to be a few that can play a role in moisturizing and helping growth), for those who want plants and crops to thrive, it is indeed very precious.

The reason why it rarely rains in the spring...

Because spring rain can moisten all things and help the growth of many plants, spring rain is very valuable.

Why spring rain oak imitation is as expensive as oil is mainly related to the season, climate, crop habits, region, etc.

1. It is related to the season.

Autumn and winter are dry and rainy, and if there is little rain in spring, it is easy to form winter and spring droughts. Therefore, for the common people who watch the sky and eat, spring rain is more precious than oil.

2. It is related to the weather and climate characteristics of spring.

In spring, the temperature rises and there are many windy days. Under the exposure of sunlight, the evaporation of soil water causes serious water dispersion loss. At this time, a spring rain to moisten the land is particularly valuable.

3. It is related to the large amount of water required by overwintering crops.

Spring is the sowing season, and overwintering crops such as winter wheat need a lot of water from the beginning of greening to the milky maturity stage. Crops such as corn and cotton also need plenty of water to grow. Therefore, the rain in spring is more precious than oil, because it is closely related to the harvest of crops.

4. It is related to the region.

The spring drought in North China is more serious, and the spring rain accounts for less than 15% of the annual precipitation, so there is a saying that the spring rain is as expensive as oil. The difference is that in South China and Jiangnan in China, the rainfall increases due to the action of warm and humid air and cold air, and there is often a saying that "it rains a lot during the Qingming Festival".

Spring is the time when overwintering crops such as winter wheat need a lot of water from the beginning of greening to the milky maturity. Corn, cotton, etc., from sowing to seedling, also require sufficient water, thus making the spring drought more prominent. At this time, if there is rain to come, it is naturally very precious, so there is a saying that "spring rain is as expensive as oil".

Spring drought is more severe in North China, with spring rains accounting for 10-15% of annual precipitation, and less than 10% in some places. If there is little rainfall in autumn and winter, the temperature rises quickly in spring, there are many windy days, and evaporation is strong, which is often prone to continuous drought in autumn, winter and spring. At the same time, at this time, it is the period when the overwintering crops return to green to milk maturity, and more water supply is needed, and corn, cotton, etc. are sown into seedlings, and sufficient water is also required, so the spring drought is prominent.

At this time, if there is rain to come, it is naturally very precious, so there is a saying that "spring rain is as expensive as oil".

The climate in South China and Jiangnan is different, entering early summer, the weather is warmer, and the rainfall in the above areas increases due to the combined effect of warm and humid airflow and cold air. Around April every year, there is a pre-flood season in various parts of South China, and then the rain belt advances from south to north. As a result, there are more spring rains in the south.

The season of the year is in spring, when everything awakens and takes root and sprouts in spring. All plants need to be moistened by rainwater, and if there is not enough rain, it is likely that they will not be able to be cultivated, and the end result will be no harvest. Therefore, the importance of spring rain can be imagined.

In addition, China has always been a big agricultural country, and the common people of our ancestors have basically relied on farming to make a living. Therefore, spring rain is as expensive as oil, and this is where it comes from.

The reason why spring rain is as expensive as oil:

1. It is related to the large amount of water required by overwintering crops in spring

Spring is the time when overwintering crops such as winter wheat need a lot of water from the beginning of greening to the milky maturity. Corn, cotton, etc., from sowing to seedling, also require sufficient water, thus making the spring drought more prominent.

2. It is related to the season:

Spring is the transition from the two rainy seasons of winter and autumn, if there is little rainfall in winter and autumn, the soil moisture itself is not good, and it is often easy to form winter and spring drought.

3. It is related to the weather and climate characteristics of spring

In the spring of northwest and north China, the temperature rises quickly, there are many windy days, and under the sun, the soil moisture evaporates strongly, resulting in water dispersion and loss. In addition, in spring, China's warm air force is not very strong, and the warm and humid air currents from the ocean mostly collide with the cold air in China's southern China and Jiangnan areas, bringing abundant rain there. It is only with the strengthening of the summer monsoon that a large number of warm and humid airflows can reach the northern part of China.

At this time, if there is rain, it is very precious.

Good rain knows the season, when spring happens.

It's about spring rain.

Spring rain is as expensive as oil because:

In the northern part of China, the rainfall in winter and spring is scarce and dry. In spring, crops that have almost stopped growing in the harsh winter begin to "regreen", and the stems and leaves gradually turn from yellow to green, and many crops begin to be sown. Therefore, adequate moisture is particularly needed in spring.

At this time, if you can get a few more rains, of course, it is especially precious.

However, the force of warm air in spring has not yet been able to move north to the north of the Yellow River, and the cold and warm air currents mostly converge in the areas south of the Yangtze River, resulting in the main rain areas staying in the areas south of the Yangtze River. However, there is not much chance of rain in the area north of the Yellow River, and rainfall is still very scarce. Therefore, the next spring rain is very gratifying, so there is a saying that "spring rain is as expensive as oil".

As for the south, there is more chance of rain in the spring, so this statement does not apply.

Spring is the time when all things come to life, and rain is rare and precious for all living things.

The content of nitrogen in the air is four-fifths of the volume, in a thunderstorm, nitrogen and oxygen produce nitric oxide (N2+O2 2NOo), and nitric oxide will be combined with oxygen to produce nitrogen dioxide (2NO+O2 2NO2), nitrogen dioxide and rainwater fall into the ground together, because nitrogen dioxide reacts with water to form nitric acid and nitric oxide (3NO2+H2O 2Hno3+NO), which is actually applying nitrogen fertilizer to crops. Therefore, spring rain is as expensive as oil.

Spring rains are scarce and not heavy, which has a great effect on the growth of crops.

Because of the spring rains. It has a great effect on crops.

Because everything has just woken up in spring, it needs the moisture of rain, and the spring wind is strong, and it is difficult to rain, so spring rain is as expensive as oil.

Spring is the season of sowing, and it takes rain for seeds to germinate, so it is said that spring rain is as expensive as oil.

Related to the season: Spring is followed by autumn and winter, and if there is little rainfall in autumn and winter, the soil moisture itself is not good, and it is often easy to form winter and spring droughts.

Spring, also known as spring, is the first season of the four seasons, referring to the period from the beginning of spring to the beginning of summer, including the beginning of spring, rain, stunning, vernal equinox, Qingming, and valley rain. It is the season of revival. In the Northern Hemisphere the Gregorian calendar is the beginning of February and the beginning of May, while in the Southern Hemisphere (e.g. Australia) it is 9 November.

Meteorologically, spring begins with an average temperature of 10 or more for 5 consecutive days. The spring climate is warm and moderate, with rain in most parts of Chinese mainland, and everything is full of vitality, and the climate is changeable, warm and cold.

Spring and March, this is called Chen, heaven and earth are born, all things are glorious, lie down at night and get up early, wide (more) steps (walk) in the court, and be slowed down (meaning unbound), so as to make Zhisheng. Don't kill if you're born, don't take it away, reward it but don't punish it, this spring should be the way to maintain health. Otherwise, it hurts the liver, summer is cold, and there are few elders.

There are several reasons why "spring rain is as expensive as oil":

First of all, spring follows the autumn and winter seasons of the previous year, and if there is less precipitation in autumn and winter, and the soil moisture is not good, it will often form a winter and spring drought.

Spring is the regreening period for overwintering crops such as winter wheat, which requires a lot of water. Spring-sown crops also need sufficient water from sowing to emergence, so spring rain is very precious.

However, the cold and warm airstreams in spring converge mainly in the south, causing the rain zone to stay in the south. In the north, there are few opportunities for rain, and the amount of rain is relatively small, so there is a saying that "spring rain is as expensive as oil". And there are many opportunities for rain in the south, so this statement is inappropriate.

The above is an excerpt from Milley's children's book "Natural History Lessons in the Field".

"Spring rain is as expensive as oil", mainly talking about North China. In North China, the spring precipitation is low and the spring drought is more serious, so winter wheat has been planted in history. Spring follows the arrival of autumn and winter, two rainy seasons, and at the same time, spring temperature rises quickly, windy and evaporative strong, which is easy to form drought.

In addition, winter wheat is just right at this time; The two-month overwintering is the critical stage from rejuvenation to jointing, spikelet differentiation and growth, and the water demand is large.

Therefore, the problem of spring drought is particularly prominent. At this time, if there is precipitation, it is naturally particularly precious, so there is a saying that "spring rain is as expensive as oil".

There is little rain in the spring, but it is true that crops need water most – for sowing.

The northern part of our country is dry in winter, and in spring, the temperature rises, crops begin to grow, and the water demand increases.

In the northern part of China, the rainfall in winter and spring is scarce and dry. In spring, crops that have almost stopped growing in the harsh winter begin to "regreen", and the stems and leaves gradually turn from yellow to green, and many crops begin to be sown. Therefore, adequate moisture is particularly needed in spring.

At this time, if you can get a few more rains, of course, it is especially precious.

You may be a city person, the spring rain is as expensive as oil, and ordinary people understand the truth. In spring, many crops are planted in the countryside, and all plants need sunlight and water, so the spring rains at this time are particularly important, so they are as expensive as oil. I think if you are from the city, you will have a certain harvest if you have time to go to the countryside often.

It is related to the climatic characteristics of spring.

Xie Jin is short and good at arguing, good at coupling sentences, quick thinking and frank temperament. Legend has it that when he was a child, he fell down in the rain, causing passers-by to laugh, and he casually wrote a poem: "The spring rain is as expensive as oil, and it rains all over the streets." Fell down and laughed to death a herd of cows. ”

In the north, there is a saying of "Ruixue Trillion Year", first, Ruixue has accumulated enough water for the beginning of spring; the second is that Ruixue insulates the crops in the ground; The third is that some pests will die from Ruixue. And "spring rain is as expensive as oil" has brought opportunities for spring ploughing, spring sowing, and spring planting in the south, especially Wangtiantian, which "relies on the sky to eat".

From the poem "Spring Rain" by Xie Jin in the Ming Dynasty: "The spring rain is as expensive as oil, it flows all over the streets, slips and falls to solve the bachelor, and laughs at a group of cattle." ”

According to the folk romance, the Ming Dynasty's Xie Jin Imperial Examination High School, received the good news, couldn't hold back the excitement, and informed the relatives and friends, because of the rain and slippery roads, accidentally fell, the villagers in Jishui County were full of mud, wet clothes, embarrassed, and laughed. Xie Jin wrote a poem on the spot, and chanted this poem on the spot, and ridiculed the neighbors who saw the joke.

The saying that spring rain is as expensive as oil" is mainly spread in the northern region represented by North China. Spring precipitation is scarce in North China, accounting for only 10%-15% of the annual precipitation, and even less than 10% in some areas. In addition, the autumn and winter seasons before spring are also the seasons with low precipitation, so if the spring precipitation continues to be low, it is easy to cause continuous drought.

And more importantly, spring is an important time for many crops in North China, Huanghuai and other places to return to green. The so-called "rejuvenation" mainly refers to the fact that crops that have almost stopped growing in winter will turn from yellow to green in the spring and resume growth, especially when water is needed. Therefore, if rain falls at this time, it can not only alleviate the drought, but also moisturize the crops, which is naturally very valuable.

Therefore, there is a saying that "spring rain is as expensive as oil". The original text of this sentence is from Song Shi Daoyuan's "Jingde Chuan Lantern Record" and Ming Xie Jin's "Spring Rain".
