Today at 6:34 in the summer solstice, China will enter the hot 60 days. This dog is July 17th ~7 month 26 days, the ambush is July 27th ~8 month 15 days, Mofu is August 16th ~8 25. In this season, to try to avoid high temperatures in the afternoon to go out, diet can be light.
The summer solstice is a solar term in twenty-four to determine the first solar term. Seventh Century BC, Chinese ancestors used to measure the shadow, the summer solstice. The annual summer solstice from June 21st (or 22), and July 7th (or 8) end. According to "abide by the constitution of the transcript:" day "to the north, day long to fall short, this summer. To the person, is also very." The summer solstice, the location of direct sunlight ground reached the northernmost one year almost directly in the northern regression line (latitude 23 degrees 26\ '), the longest day of the northern hemisphere, and the North day is long. Haikou City, such as the day of Hainan, a little more than 13 hours, Hangzhou city for 14 hours, about 15 hours, while Mohe County, Heilongjiang, Beijing, up to 17 hours or more. After the summer solstice, the sun ground position gradually moved south, the northern hemisphere gradually shortened day. People have to eat in summer, one day short line ". At a time when the southern hemisphere midwinter.
Ancient China will be divided into three periods: the summer solstice "one candidate antler solution; two candidate cicada Ming start; three when raw pinellia." The deer is the same family with MI, but the ancients believed that the two genus of yin and yang. The horns of a deer in the former, so is yang. Yin and Yang was born on the summer solstice decline, so he started off positive. And Mi due to belong to Yin, so in the winter solstice angle before falling; the male cicada in summer due to the sense of yin and wings and Ming; pinellia tuber is a shade loving herbs, being born in the midsummer of marshes and paddy field, so its name. Thus, in the hot summer, some shade creatures began to appear, while the positive biological began to decline.
Our country folk to the 15 day after the summer solstice is divided into 3 "," general head for 3 days, in 5 days, at the end of the 7 day. During this period, most areas of China, the temperature is higher, the sunshine is sufficient, the crop growth is very fast, physiological and ecological water demand are more. The precipitation has great impact on agricultural production, "summer rain worth". In general, the precipitation in the middle and lower reaches of the Yangtze River and the Huang Huai area can generally meet the requirements of crop growth. "Age Jingchu" in mind: "in June there will be three rain, Tian Yi Li thought Ganse, aiga." Visible in more than 1000 years ago, people have a clear understanding of the characteristics of rainfall.
Before and after the summer solstice, the Huaihe River in south rice during heading and flowering, field water management to enough water heading, moist filling, dry dry wet, both to meet the need of water rice seed and breathable to keep a good root to ensure ripe work to the old, increase grain weight. As the saying goes: "don't let this summer, summer sowing work to start, has been broadcast to strengthen management, and strive to all seedlings. After emergence and seedling time should be fixed by transplanting seedlings. Summer solstice season variety of farmland weeds and crops growth quickly, not only with the crop water fight fight fat sunshine, and is host to a variety of pathogens and pests, so Nongyan said: "summer hoe root edge grass, like raising a viper bite. "To the row hoeing is one of the measures of increasing summer season. Cotton has been generally squaring, vegetative growth and reproductive growth excluding, should pay attention to the timely overall technical pruning, cultivation and banking, the area is a lot of rain to do field drainage ditch clearance work to prevent waterlogging and storm damage.
"Hot in summer", "summer solstice three G number of head". The summer solstice said that although the hot summer has arrived, but is not the hottest, within a period of time after the summer solstice temperature continues to rise, another twenty or thirty days, usually the hottest weather.
After the summer solstice, in most parts of South China agricultural production due to the growth of the crops is vigorous, weeds, pests and rapidly grow and spread into the field management period, plateau pasturing area began Wang grass fattened animals from the golden season. At this time, a significant increase in western South China rainfall, since the spring rainfall in southern China East West of the distribution situation, gradually transformed into xiduodong is little. As a general summer drought, then is expected to be lifted. In the past thirty years, the number of large scale flood occurred in the west of Southern China in late June, although not much, but the degree is more serious. Therefore, special attention should be paid to prepare for flood prevention. The summer solstice is the solar term in eastern Southern China annual rainfall up to the next solar term, often under the control of the subtropical high, drought. In order to enhance the ability to drought, to seize the agricultural harvest, in these areas, to grab before the rain is an important measure of rain.
After the summer solstice the ground is strongly heated air convection, the afternoon and evening thunderstorms often form. This heat thunderstorm has come to disease, the rainfall range is small, people called Xia Yu across the ridge. Tang Dynasty poet Liu Yuxi in the south, skillfully metaphor in this weather, write sunrise east west rain, is not clear but clear of the famous poem.
