Is hot the first day of summer?

Entering the dog days is entering the dog days. "beginning of autumn in the third year from summer to Sunday", which is the foundation of beginning of autumn. The first day of this year is July 13. "Three volts" refers to the front, middle and back three volts, that is, from mid-July to mid-August. From summer to the third "night" in the future, the first day, the middle day and the last day are the hottest days of the year.

The high temperature in summer is not the hottest time. It will be very hot after entering the heat. Usually, the hot summer begins with the hot summer solar terms. The day when the third Boxer Day starts from the summer solstice every year is the day of lodging, and the date of lodging is different every year.

The dog days are determined according to the law of "counting days by branches" in ancient China. Every summer to the future, the third Geng Day is the first, the fourth Geng Day is the middle, and the first Geng Day after beginning of autumn is the last. Together, it is called the third volt. According to the solar calendar, it appears from mid-July to mid-August. At this time, most parts of our country are the hottest season of the year.

Therefore, it can be seen that summer heat is not the first summer heat, nor is it the beginning of summer heat.

What does summer heat mean?

The summer heat is "summer heat", which means that although the weather is already hot, it has not yet reached the hottest time of the year, and the summer heat is only the beginning of the summer heat. Monsoon climate is the main feature of China climate. Monsoon climate is a mixture of continental climate and maritime climate. Summer is affected by the warm and humid air flow from the ocean, which is hot, humid and rainy. The high temperature in monsoon climate is basically the same as that in rainy season, and the rain and heat are in the same period, which is beneficial to crop growth. In hot summer, the weather is hot and thunderstorms are frequent, which is the season when everything grows wildly.

In the hot summer, the rainy season in the Jianghuai Valley is drawing to a close, and the temperature in long summer is rising, entering the summer drought period. However, in the rainy season in North China and Northeast China, tropical cyclones are active frequently, and the number of tropical cyclones landing in China begins to increase.

The average summer temperature in southern China is about 26 degrees Celsius. In mid-July, the average daily temperature of more than 30 days and the maximum daily temperature of more than 35 days can begin to appear in the low-altitude valley areas in southeastern China. In the northern part of the northwest plateau, frost and snow can still be seen at this time, which is equivalent to the scene of early spring in South China.

At the beginning of the summer heat, the plum rains in the Jianghuai basin ended one after another, and the southeast monsoon rainy season from the Pacific Ocean began to spread in the vast areas north of the Huaihe River and east of the Qinling Mountains. Precipitation has increased significantly, and rainfall is relatively concentrated. South China, Southwest China and Qinghai-Tibet Plateau are also in the southwest monsoon rainy season from the Indian Ocean and the South China Sea. Under the control of subtropical high, the weather in the middle and lower reaches of the Yangtze River is usually high temperature and little rain. In some years, the cold air in the north is still strong before and after the summer heat, which is evenly matched with the warm air in the south of the middle and lower reaches of the Yangtze River, leading to frontal thunderstorms. Thundershowers in midsummer are often the weather information of "plum falling", which indicates that the rain belt will stay in the middle and lower reaches of the Yangtze River for some time.

Before and after the summer heat, most parts of southern China entered the season with the most thunderstorms. Thunderstorm is a disastrous weather phenomenon, often accompanied by strong winds, heavy rain and sometimes hail, which is easy to cause disasters. In eastern South China, after the high temperature in summer, it is often controlled by the subtropical high, and it is often sunny and hot, and it begins to enter the summer drought period.

Before and after the summer heat, except for the winter and spring wheat harvest in the northeast and northwest, agricultural production was mainly busy with field management. Early rice is in the late filling stage, and early-maturing varieties should be harvested before the heat, and the fields should be kept dry and wet. When mid-season rice enters the booting stage, it should be topdressing according to its growth to promote large panicles and more grains. The single-season late rice is tillering, so tillering fertilizer should be applied as soon as possible. Double seedlings should be protected against pests and diseases, and full "marriage fertilizer" should be applied 5-7 days before sowing. "The heat is unbearable, and the cotton keeps pruning." In most cotton areas, cotton began to bloom and spit, and its growth was the most vigorous. When applying boll fertilizer again, the old leaves should be pruned, branched and removed in time to coordinate the distribution of nutrients in the plant, enhance ventilation and light transmission, improve the microclimate of the population and reduce the shedding of buds and bolls. High temperature is the high season of aphids, red spiders and other pests, and timely control of pests is another important link in field management.

It's a little hot in summer, but not very hot. Speaking of summer heat, it's the hottest time of the year. In the hot summer, the rainy season in the Jianghuai Valley is drawing to a close, and the temperature in long summer is rising, entering the summer drought period. However, in the rainy season in North China and Northeast China, tropical cyclones are active frequently, and the number of tropical cyclones landing in China begins to increase.
