Forcibly point to which solar term?

There are many sayings about solar terms in beginning of spring in rural areas, such as "beginning of spring is sunny and easy to farm". What does this proverb mean? Does the old saying make sense?

It was a sunny day in early spring, and plowing was effortless. This means that if the weather is clear in the solar terms in the spring, it will be a good year, farmers will become very convenient to farm and have a good harvest without any effort. On the contrary, if it rains at the beginning of spring, this year will be very bad and the harvest of crops will be affected.

Twenty-four solar terms are the product of agricultural civilization. The ancients formulated today's 24 solar terms by observing the law of celestial bodies' movement and according to the influence of celestial bodies' movement on seasons, climate and phenology. In the past twenty-four solar terms, the solar terms were determined according to the bucket handle rotation direction of the Big Dipper. Now, solar terms are determined according to the position of the sun on the ecliptic. The time for the sun to run on the ecliptic is 360 degrees, which is divided into 24 equal parts on average, that is, every 15 degrees is an equal part. When the sun moves to 365,438+05 degrees of the ecliptic, it is the beginning of spring solar term, which is celebrated every February 3 -5.

After understanding the origin of the twenty-four solar terms and the solar terms in beginning of spring, let's take a look at the influence of the sentence "It's sunny in beginning of spring, and it's easy to plow" on farming. Beginning of spring is the beginning of spring. After beginning of spring, the ground temperature and temperature will continue to rise, and the weather will become warmer and warmer. After the spring, farmers will begin to arrange the new year's farming. Farmers find that when the solar terms in beginning of spring are clear, the cold air will no longer move frequently after beginning of spring, so the weather will become warmer and warmer after beginning of spring, and the rising temperature is suitable for farmers to farm. However, if it is cloudy or rainy in beginning of spring, it means that the cold air is still very active at this time, so the temperature in beginning of spring will be hot and cold, which will be very unstable, which will have an impact on farmers' farming. Therefore, there is a saying that "beginning of spring will be sunny and easy to cultivate".
