About the weather

Since February 20, 65438, the biggest snowfall since the winter of this year has generally come to northern Xinjiang, parts of the eastern part of northwest China, most of North China, Huanghuai Jianghuai, northern Hubei and other places. Although heavy snow has a negative impact on transportation, snowfall moistens the soil, kills pests and diseases, and purifies the air, which is beneficial to agricultural production and people's health.

It will snow when it should snow in winter, and agricultural production will gain a lot after it snows. There is a widespread saying among the people in our country that "snow will bring a good harvest", which means that there will be several heavy snows in winter, which indicates a bumper harvest of crops in the coming year.

This is because the weather is cold in winter and the snow is often not easy to melt. The snow covered on the soil is soft, there are gaps between snowflakes, which are filled with air, and the air has poor thermal conductivity. It's like covering a crop with a quilt. No matter how cold it is outside, the temperature below will not drop very low. When the cold air passed, the weather gradually became warmer and the snow gradually melted, which not only protected crops from freezing damage, but also left the water melted by the snow in the soil, saving a lot of water for crops, which was very beneficial to spring ploughing and sowing and the growth and development of crops.

Besides, snow will kill pests. 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. Therefore, several heavy snows in winter are a harbinger of a bumper harvest in the coming year.

This winter, heavy snow has appeared in most areas of North China, Huanghuai, Jianghuai and Hubei, which indicates that next year will be a bumper harvest year.
