If you are not afraid of the first frost rain, you are afraid of the first frost sunny day. What do you say about the first frost today? Look at what the agricultural proverb says.

I'm not afraid of the first frost and rain, but I'm afraid of the first frost and fine. It's the first frost today. What's your opinion? See farmers' proverbs as follows:

The first frost is the eighteenth of the twenty-four solar terms and the last solar term in autumn. It marks the end of autumn and the coming of winter, when the temperature drops gradually, the ground temperature drops to about 0℃, and the water vapor in the air condenses into frost. In rural areas, there are many agricultural proverbs and sayings about the solar term "first frost", the most popular of which is "first frost is afraid of rain, first frost is afraid of sunny".

This agricultural proverb means that if the first frost is rainy, the temperature in winter is relatively warm and the crops grow smoothly. On the contrary, if the first frost is sunny, the winter temperature may be cold, which is not good for crop growth. This is mainly because there is enough water vapor in the air under rainy weather conditions, which is conducive to soil wetting and thus to the growth of crops in winter. On the other hand, sunny days mean that the ground radiation cools faster.

In today's first frost, we can interpret this agricultural proverb from the following aspects to understand the first frost solar terms:

1. Climate change: In the first frost season, the natural temperature drops and the water vapor in the air condenses into frost. This has an important impact on the growth of crops. On the one hand, it is beneficial to kill pests and germs in farmland, thus reducing the occurrence of pests and diseases; However, on the other hand, too low temperature may have a negative impact on crop growth, which requires farmers to strengthen field management.

2. Agricultural farming: In the first frost and solar terms, farmers should start preparing for winter ploughing, ploughing and fertilizing the land to create favorable conditions for winter crop growth. In addition, it is necessary to strengthen farmland inspections and take timely pest control measures to ensure a bumper harvest of winter crops.

3. Livestock and poultry management: In the first frost season, when the temperature drops, livestock and poultry are prone to catch cold and get sick. Therefore, farmers' friends need to strengthen the cold-proof and warm-keeping work for livestock and poultry, provide sufficient feed and drinking water to ensure the safety of livestock and poultry in winter.
