Has long summer entered summer?
(1) On the solar terms, long summer bid farewell to spring and is the beginning of summer.
(2) From the climatological point of view, long summer is only when the daily average temperature rises above 22℃, but it is not long summer in the long summer;
"The bucket refers to the southeast, and the dimension is long in summer. Everything grows here, hence the name Long Summer. "
Twenty-four solar terms: Long Summer and April Festival. Make a word to understand spring. Summer, holidays. At this time, everything is fake and big. "
From the semantic point of view, the word "summer" here means "big", not summer, but the plants sown in spring have grown upright. In addition, according to the standard of climatology, summer begins when the average temperature of that day rises steadily above 22℃. At this time, the average temperature in most parts of the country is around 18-20℃, so the "long summer" is not the long summer we imagined.
In the long summer season, only the area south of Fuzhou-Nanling line in China is the real summer of "the trees are dark and the day is long, and the balcony reflects into the pond", while some areas in the northeast and northwest have just entered the spring.

Climatic characteristics of long summer: hot summer is coming, and thunderstorms are increasing.
After the long summer, Jiangnan officially entered the rainy season, and the rainfall and rainy days increased significantly. Continuous rainy days not only caused wet damage to crops. It will also cause the prevalence of many diseases. In particular, some wheat and rice crops are prone to pests and diseases, and people who are also engaged in agricultural work can pay attention to the prevention and control of pests and diseases.
Before and after the long summer, the temperature in North China and Northwest China rose rapidly, but the precipitation was still not much. In addition, the wind is strong and evaporation is strong in spring. Atmospheric dryness and soil drought often seriously affect the normal growth of crops. Especially, the dry hot wind before and after wheat filling and milk ripening is an important disastrous weather that leads to yield reduction, and timely irrigation is the key measure for drought resistance and disaster prevention. "hoes are everywhere for three days in the long summer", when weeds grow rapidly. "Don't mow the grass for one day, and don't mow it for three days." Intertillage weeding can not only weed, resist drought and prevent waterlogging, but also increase the ground temperature and accelerate the decomposition of soil nutrients, which is of great significance to promote the robust growth of crops such as cotton, corn, sorghum and peanuts at seedling stage.
After the long summer, it is a critical period for early rice planting, and rain will come sooner or later. The rainfall during this period is closely related to the future harvest. The farmer's proverb says well: "If it doesn't last long in summer, the plow will hang high." "There is no rain in the long summer, and there is no rice in the head." There is also a folk custom of weighing for fear of summer heat. It is said that after weighing yourself on this day, you will not be afraid of being hot in summer and will not lose weight. Otherwise, it will be unlucky if disasters continue.
In addition, Jiangxi has the custom of drinking tea in the long summer, saying that if you don't drink tea in the long summer, you will suffer all summer. As early as ancient times, kings often went out of the city to welcome summer on the first day of summer, and the day to welcome summer was long summer.
