What solar terms are not hot?

When the solstice of summer came, the old man said, "There are three fears in the summer solstice of Dragon Boat Festival." Details are as follows:

1, the first fear is "summer solstice is not hot"

Although summer solstice is the fourth solar term in summer, it means that summer is coming, so summer solstice is also the beginning of hot summer. According to the observation experience of the old people, it is "not hot until the summer solstice", that is to say, the weather should get hot after the summer solstice.

However, if the weather is still cool during the summer solstice, even lower than the temperature of the same period last year, this indicates that abnormal weather may occur in the future. This abnormal weather will have a negative impact on the growth and development of crops, which may lead to reduced harvest or even no grain harvest.

High temperature is very important for the growth of some crops, especially summer crops, which need enough temperature to provide energy and promote photosynthesis. If there is not enough high temperature, the growth of these crops will be limited, which may lead to a decline in yield.

2. The second fear is "it doesn't rain from summer to Sunday".

Summer is the rainy season in many parts of China, so it is especially necessary to pay attention to the rainfall from summer to the future. If it doesn't rain for a long time from summer to the future or the precipitation is obviously insufficient, it will lead to drought. Drought is extremely unfavorable to the growth and development of crops. Crops lacking water are prone to wilting and slow growth, which may lead to death in severe cases.

According to long-term observation, the ancestors came to the conclusion that it rained on the day of summer solstice, so there was enough rain behind it. On the contrary, if it doesn't rain on the summer solstice, there will be less rain behind, and there is a great possibility of drought.

The third worry is that "the summer solstice solar terms blow the west wind".

Southeast winds are usually dominant in summer, but after the summer solstice, westerly winds may blow in some areas. This westerly wind is often accompanied by high temperature and dry weather, which has a negative impact on crop growth. The dry westerly wind can easily lead to the rapid evaporation of soil moisture, aggravate the development of drought, and may also bring disastrous weather such as sandstorms and damage farmland.
