Whether the first snow can cover the earth, to cover the land covered with ice and snow, must be

Summary. There are two types of snow, one is continental and the other is oceanic. Due to the cold climate, there are relatively few plants and animals that survive in the snow.

To the snow-covered earth, it must be.

1. Snow helps to keep the soil warm, and has an anti-freezing and warming effect on overwintering crops. The snow that falls to the ground is loose and porous, and it can contain 40 50 percent air. Because air does not transfer heat easily; And because of the cold weather in winter, the snow is often not easy to melt; The earth is like a big, soft quilt.

This "quilt" prevents the heat in the soil from escaping outwards and prevents the invasion of cold air from the outside.

Second, snow cover is conducive to increasing soil moisture. After the cold, the weather warms up, the snow slowly melts, and the melted snow water loses less, and most of it seeps into the soil, just like an irrigation, which is very good for alleviating the spring drought and doing a good job of spring plowing and sowing.

3. Snow contains a lot of nitride, which can improve soil fertility. Snow adsorbs a large amount of free gases in the air and produces nitride back-shielding through chemical reactions. It has been observed that if 1 liter of rain can contain milligrams of nitride, then 1 liter 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.

This is the first snow on the Jiaodong Peninsula since the beginning of winter.

The snow was blowing and it was falling heavily. At first, there was a light rain, and soon there were large snowflakes from the cloudy sky.

Falling down. The ground was white for a while. In winter, the mountain village is silent at night, and only the snowflakes are heard falling continuously.

Falling, the dead branches of the trees were crushed by the snow, and occasionally creaked.

It snowed heavily all night. This morning, the sky cleared and the sun came out. Push open the door and look, ho! It's a lot of snow! Mountains, rivers.

The trees and houses were all covered with a thick layer of snow, and thousands of miles of rivers and mountains prospered, turning into a world of pink makeup and jade. The willow trees with all their leaves hanging over.

fluffy, shiny silver bars; The evergreen pine and cypress trees in winter and summer are covered with fluffy and heavy snowballs. One.

The gust of wind blows, the branches of the trees sway gently, the beautiful silver streaks and snowballs fall down in a fluttering stream, and the jade shavings of snow dust flutter and reflect in the wind.

The morning sun shows a rainbow of colors.

The snow on the street was more than a foot deep, and people creaked under their feet when they stepped on it. Groups of children were building snowmen and throwing snowballs in the snow, and the joyful shouts shook the snow off the branches.

As the saying goes, "Ruixue is a mega year". This statement has a strong scientific basis and is not a superstitious idiom. Heavy snow in the cold winter can freeze to death.

part of the overwintering pests; The melted water seeps deep into the soil and can be used to grow crops. I believe this is timely.

Heavy snow will certainly boost next spring's crops, especially wheat. Experienced old farmers liken snow to "wheat quilts". Winter "cotton."

The thicker the quilt is covered, the better the wheat will grow next spring, so there is a proverb (21): "In winter, the wheat is covered with three layers of quilts, and the next year the pillow will be dismantled with steamed buns (22)."

Sleep. I think that's why people (23) call the timely heavy snow "snow."
