Xue Rui refers to the right amount of snow at the right time. Proper amount of snow can not only kill insects and keep warm, but also provide water for crops without crushing them, so it is regarded as a sign of bumper harvest. Xue Rui means good snow.
Xue Rui effect:
1, warm soil
Soil moisture conservation and water storage field. It's cold in winter, and the snow often doesn't melt easily. The snow covered on the soil is soft, and there is a lot of stagnant air hidden inside. Air doesn't transfer heat, just like covering a quilt for crops. No matter how cold it is outside, the temperature below will not drop very low.
Step 2 freeze pests to death
Snow has a thermal insulation effect on the soil, which is temporarily beneficial to pests who go underground for the winter. But when snow melts, it absorbs a lot of heat from the soil. At this time, the soil will suddenly become very cold, the temperature will drop a lot, and pests will freeze to death.
