The significance of the Great Cold Season
The Great Cold is not only the last of the 24 seasons, but also the coldest one. The Great Cold is a solar term that reflects the process and degree of temperature rise and fall. During the winter solstice, the sun shines directly on the Tropic of Capricorn, and the ground in the northern hemisphere receives the least light and heat. The weather should be the coldest, but the actual coldest occurs during the Minor Cold and Major Cold periods after the winter solstice, which is the so-called "cold in March." However, during the Great Cold Season, the ground basically absorbs little temperature. Instead, there is more radiation from the ground, and ultraviolet rays are more severe in winter. The temperature continues to drop during the Great Cold Season, and it is easy to experience cold temperatures during the Great Cold Season.

In warm winters, wheat and rapeseed sown too early tend to grow too vigorously, joint and bolt in advance, and their cold resistance is greatly weakened, making them vulnerable to low-temperature frosts. Therefore, the planting plan will be changed according to the environmental level that the plants accept. Crop varieties will be selected according to local conditions, sown at the right time, and effective promotion and control measures will be taken. In this way, even after a very harsh winter, plants and crops can have a good life. the beginning of. What does Dahan mean? 2
