In winter, the snow falls in Ruixuepu, and the snow is very cute Why is the snow precious

In a good year, the snow layer protects the overwintering crops, and the newly fallen snow is loose and porous, which can contain 40% to 50% of the air. Because the air is not easy to transfer heat, in this way, the earth is like a large and soft quilt, this quilt can prevent the heat in the soil from dissipating outward, and can prevent the invasion of cold air outside, the measurement shows that when the snow thickness is 20 cm, the surface temperature of the snow is 15 degrees Celsius lower than the surface temperature under the snow, when the snow thickness reaches 30 cm, even if the temperature drops to minus 30 degrees Celsius, the wheat will not be frost damaged.

When the earth warms up in the spring of the next year, the snow loses less snow water that slowly melts, and most of it seeps into the soil, which can not only bring more nitride to the soil, but also like an irrigation, which is very beneficial to alleviate spring drought and do a good job in spring plowing and sowing.

The role of the last paragraph is to summarize the full text, and the structure of the full text is the total score.

1. Progressive relationship.

2. Each other. You and I are crystalClarity and pleasure. Cheerfulness is precious. 3. Snow is beautiful, bizarre, and precious.

In winter, the snow falls, and the snowflakes are fluttering, which is very cute.

Snowflakes are beautiful. It is white and crystalline, exquisite, light and beautiful, like a white lotus, slowly descending from the vast space. Watching it dance all over the sky makes people think about it. The ancients compared it to the fluttering "catkins" and the blooming "pear blossoms", how worthy of praise it is!

Snowflakes are bizarre. Each small snowflake is an extremely delicate pattern. They have both commonalities and styles.

Some are like bright little stars, some are like thin clothes needles, some are like hexagonal petals, and some are like six small umbrellas ...... openIt's really beautiful in a variety of ways. There are many collectors of snowflake patterns in the world, who have taken thousands of snowflakes with their life's energy, but they have not found the same snowflake patterns as each other.

Ruixue is precious, it can reduce the soil temperature, freeze pests, it can moisten the soil, so that crops have enough water, it also contains a lot of nitrogen compounds, is a good fertilizer for crops.

A reading question!

In winter, the snow falls, and the snowflakes are fluttering, which is very cute.

Snowflakes are beautiful. It is white and crystalline, precious and clear, light and good-looking, like a white lotus, slowly descending from the vast sky, watching it fly all over the sky, making people think high. The ancients compared it to the fluttering "catkins" and the blooming "pear blossoms".How worthy of praise it is!

Snowflakes are bizarre. Each little snowflake is an extremely delicate pattern. They have both commonalities and styles.

Some are like bright stars, some are like thin clothes needles, some are like hexagonal petals, and some are like six small fans that are open. There are many collectors of snowflake patterns in the world, who have spent their lives taking thousands of snowflakes, but they have not found the same snowflake patterns as each other.

I was so happy because my mom was going to take me to the park.

Ruixue, and there is no specific time.

Ruixue refers to snow that falls moderately at the right time. The right amount of snow can kill insects and keep warm, and can provide crop moisture without crushing the crops, so it is regarded as a good omen of a good year, and Ruixue is the meaning of good snow. Proverb:

There are folk proverbs such as "Ruixue Trillion Year" and "Wheat covers three layers of quilts in winter, and sleeps with steamed buns in the coming year", which means that a few heavy snowfalls in winter are a harbinger of a good harvest in the coming year.

Ruixue, there is no specific time.

Typical snow is a gentle and moderate amount of snowfall.

The right amount of snow is regarded as a harbinger of a good year because it can kill insects and keep them warm, and it can provide moisture to the crops without crushing them.

Source: Southern Dynasty Chen Zhang Zhengjian poem "Xuanpu Watching Spring Snow": "The same clouds reflect the mountains, and the snow is near the air." ”

Example: Jun Qing's poem "Autumn Color Fu Ruixue Picture": "Ah, what a painting of the cold winter of the northern country and the harvest year of Ruixue Zhu Xuanxian's Chinese painting "Ruixue Red Flower Picture"! ”。Zhu Xuanxian's art works: Chinese painting "Ruixue Red Flower Picture", print "Ruixue People's Family".

Rui: Auspicious. Ruixue: Good snow at the right time.

Interpretation: It should be good for the snow. In order to be able to kill insects and make noise and keep warm, it is mostly regarded as a harbinger of a good year, so it is called.

Example: Jun Qing's "Autumn Color: Ruixue Picture": "Ah, what a picture of the cold winter and snow harvest year in the north! ”

Addendum: There is a folk proverb that "the snow is a good year", which means that a few heavy snowfalls in winter are bent and burned, which is a sign of a good harvest in the coming year.

But nowadays people often use Ruixue to refer to good snow, and Rui represents auspiciousness.

That's why people use snow to indicate good snow and food that people look forward to. If mine is helpful to you, thank you.

The term is derived from the phrase "Lucky Year of Snow", which means that there will be several heavy snowfalls in winter, which is a sign of a good harvest in the coming year.

The reason is: the winter weather is cold, the snow is often not easy to melt, the snow covered on the soil is relatively soft, there is a gap between the snowflakes and the snowflakes, the gap is filled with air, and the air has poor heat conduction characteristics, so it is like covering the crops with a quilt, no matter how cold the weather is, the temperature below will not drop very low. After the cold air passes, the weather gradually warms up, and the snow slowly melts, which not only protects the crops from frost damage, but also keeps the water from the snow melt in the soil, which stores a lot of water for the crops, which is very beneficial to spring plowing and sowing and the growth and development of crops.

Ruixue Mega Year.

"Ruixue Trillion Year" is a popular agricultural proverb, which means that the timely winter snow indicates that the coming year will be a good harvest. It is a harbinger of a good harvest in the coming year. Why?

One is to keep the soil warm and accumulate water in the field. In winter, the weather is cold, the snow is often not easy to melt, the snow covering the soil is relatively soft, there is a lot of non-flowing air inside, the air does not transfer heat, so it is like covering the crops with a quilt, no matter how cold the weather outside, the temperature below will not drop very low. After the cold wave passes, the weather gradually warms up and the snow slowly melts, so that not only does the crops not be damaged by frost, but also the water that melts down the snow stays in the soil, which accumulates a lot of water for the crops, which is very beneficial to spring plowing and sowing and the growth and development of crops.

The second is to add fertilizer to the soil. Snow contains a lot of nitride. It has been observed that if 1 litre of rain can contain milligrams of nitride, then 1 litre of snow can contain milligrams of nitride. During snowmelting, these nitrides are carried to the soil by the snowmelt water and become the best fertilizer.

The third is freezing to death pests. The snow cover acts as an insulating agent on the soil, which is temporarily beneficial for pests that burrow into the ground for the winter. But when the snow melts, it absorbs a lot of heat from the soil, and then the soil suddenly becomes very cold, and the temperature drops a lot, and the pests freeze to death.

Therefore, a few heavy snowfalls in winter are a harbinger of a good harvest in the coming year.
