Slight summer is the eleventh solar term of the twenty-four solar terms of the lunar calendar and the fifth solar term in summer, which indicates the official start of the The Last Month Of Summer season. When the sun reaches the yellow meridian 105 degrees, it is called the light summer solar term. Summer heat, which means hot, is a small heat, not very hot. It means that the weather is getting hot, but it is not the hottest yet, and most parts of the country are basically in line with it. Crops all over the country have entered the stage of vigorous growth, and field management needs to be strengthened.
The summer heat is the twelfth solar term in the twenty-four solar terms of the lunar calendar, when the sun reaches the yellow meridian 120 degrees. At this time, before and after the mid-crouching, most parts of China are the hottest period of the year, and it is also the period with the fastest growth rate of heat-loving crops.
The working people in China divide the great summer heat into three periods: "The rotten grass is firefly;" Second, wait for the soil to moisten the summer heat; When it rains, it will be fine. " There are more than 2,000 species of fireflies in the world, which are divided into aquatic and terrestrial species. Terrestrial fireflies lay eggs on hay, and when it is hot, fireflies ovulate, so the ancients thought that fireflies were made from rotten grass. The second weather is that the weather is getting muggy and the land is wet. The third weather is that there are often heavy thunderstorms, and this heavy rain weakens the heat and humidity, and the weather begins to transition to beginning of autumn.
