Slight cold and warm weather.

The agricultural proverb says, "I am most afraid of a slight cold and sunny day, and it rains and snows constantly in winter", which means a slight cold and sunny day and a lot of rain and snow in winter.

This agricultural proverb is a valuable experience summed up by the working people in our country in the long-term agricultural production practice. "Slight cold is most afraid of sunny days, and it keeps raining and snowing in winter" tells us that if it is sunny that day, it is likely that it will be rainy and snowy all winter.

This experience is based on science. Slight cold is one of the 24 solar terms, marking the beginning of winter. At this time, if the weather is clear and the temperature rises, it will warm the air near the ground and lead to unstable temperature. This will increase the water vapor in the air and form clouds and precipitation. In addition, if the temperature is high in winter, it will break the conventional climate pattern in winter, make cold and warm air meet more frequently, and lead to more rain and snow.

Winter is a critical period for crop growth. Frequent rain and snow will affect the growth and harvest of crops. Too much rain and snow will lead to too wet soil, affecting crop root growth and nutrient absorption; At the same time, rainy weather will also make the light insufficient, which will affect the photosynthesis and growth rate of crops. Therefore, if it is slightly cold and sunny, farmers need to take countermeasures in advance, such as strengthening field management, timely drainage, and increasing fertilizer application. To ensure the normal growth and harvest of crops.
