Heavy snow and solar terms harvest

An idiom in China, Rulixu zhào fēng nián, is pinyin for Rulixu zhào fēng nián, which means that timely winter snow indicates that the coming year will be a bumper harvest year. This is a harbinger of a bumper crop in the coming year. As the saying goes,' snow will bring a good harvest', and next year's wheat harvest will be very good.

Snow contains a lot of nitrides. It is observed that if 1 liter of rain can contain 1.5 mg of nitride, then 1 liter of snow can contain 7.5 mg of nitride. When the snow melts, these nitrides are brought to the soil by snowmelt water and become the best fertilizer.

"Xue Ruizhao's bumper year" lies in the anti-freezing and heat preservation effect of snow layer on overwintering crops. Heavy snow can prevent the heat in the soil from radiating outward and prevent the invasion of cold air from outside. "Xue Rui indicates a bumper harvest year" lies in the role of snow in increasing soil moisture and fertilizing. When the earth warms up next spring, the snow on the ground will slowly melt.

The loss of snowmelt water is less, and most of it seeps into the soil, just like an irrigation, which is of great benefit to alleviating spring drought and sowing well in spring. Melting snow water can bring more nitrogen compounds to the soil. The unique function of Xue Rui is determined by its own nature.
