What four solar terms do summer heat refer to?

Summer is complete, summer is hot, this is:-

Early summer

Grain Buds

Grain in Ear

Summer solstice

Minor Heat

Major Heat

Early summer

This year, the fourth day of the fourth lunar month is a long summer.

The epidemic department came, thunderstorms increased, and crops grew in the peak season. The day before Chang Xia arrived in beginning of autumn was summer.

This is the standard of dividing the four seasons in the history of astronomers. But,

The meteorological summer will be delayed by about 25 days.

It is based on 6,

7,

August is summer.

Grain Buds

A small fullness means that the wheat grains begin to be full.

However, it is not mature at this time, and the seeds of summer grain in northern China are gradually full, and the south enters the summer harvest season.

Grain in Ear

"awn" refers to crops with awns, such as wheat and barley, and "species" refers to seeds. The species of awns indicate that crops with awns, such as wheat, are mature. Before and after sowing, the rainfall and temperature in the middle and lower reaches of the Yangtze River in China increased and entered the rainy season. The air is very humid and the weather is sultry, so the middle and lower reaches of the Yangtze River in China are called "Huangmeitian".

Summer solstice

On the solstice of summer, the sun shines directly on the Tropic of Cancer. This day is the longest day and the shortest night in the northern hemisphere. From this day on, into the hot season, everything in the world grows most vigorously at this time. After the summer solstice, the temperature continues to rise, because the heat radiated from the sun to the ground is still much more divergent than that radiated from the ground to the air.

Minor Heat

Hot in summer means hot. At this time, the weather is already very hot, but it is not the hottest time, so it is called a little summer heat. At this time, it is about to enter the primary stage of "dog days" (also known as Toufu). "Dog days" is the hottest period of a year in most parts of China (commonly known as dog days).

Major Heat

The main office is just before and after Zhongfu (also called Erfu). Most parts of China are often the hottest period in a year, with high temperature of 40 degrees Celsius, which is also the fastest growing period of warm crops. This solar term is also the hottest time. Therefore, we should do a good job in heatstroke prevention and cooling.
