Snow is beneficial to the growth and development of crops. Snow is a kind of material with good thermal insulation effect, which can protect corn from frostbite in cold winter. The melting of snow water in the next spring can provide a good water supply for corn. Therefore, corn protected by snow can survive the winter safely.

In addition, snow can enhance soil fertility. According to the determination, every 1 liter of snow water contains about 7.5 grams of nitride. Snow water permeates the soil, which is equivalent to applying nitrogen fertilizer once. Feeding livestock and poultry with snow water and irrigating crops can obtain obvious benefits. At the same time, sufficient snow and water in winter can not only alleviate the drought in that year, but also provide favorable conditions for timely sowing and full seedling growth of spring-sown crops in the coming year.
