1. Snow is a kind of material with good thermal insulation effect, which can protect plants from frostbite in cold winter. The melting of snow water in the next spring can provide a good water supply for vegetation. The power of nature is definitely not a coincidence. Because of the poor thermal conductivity of snow, covering the soil surface with a layer of snow can reduce the diffusion of soil heat and block the invasion of cold on the snow surface, so the crops protected by snow can safely overwinter. Snow can also store water for crops.

It is warm to wear cotton-padded jacket in winter. This is because the porosity of cotton is very high, and the pores of cotton are filled with a lot of air. The poor thermal conductivity of air hinders the outward diffusion of human heat. The snow covering the breast of the earth is very similar to cotton, and the porosity between snowflakes is very high. It is this layer of air that drills into the pores of the snow to protect the ground temperature from falling very low.

3, the introduction of Chinese medicine, folk paving wax snow can protect vegetables and wheat, kill insects and locusts, if used for soaking grain, it will resist drought and not produce insects, and can also seal the altar to pickle vegetables.
