"The bucket refers to the southeast, and the dimension is long in summer. Everything grows here, hence the name Long Summer. " Long summer is a solar term established at the end of the Warring States Period (239 BC), which indicates the change of four seasons and the beginning of summer in four seasons. According to the standard of climatology, when the average temperature reaches 22℃ in five days, summer begins. In the middle and lower reaches of the Yellow River, the waiting temperature in the long summer season is close to the climatological standard, which is the origin of the twenty-four solar terms. From this point of view, it is practical to regard the Long Summer Festival as long summer in the 24 solar terms. According to records, during the Zhou Dynasty, on the day of long summer, the emperor personally led hundreds of civil and military officials to the suburbs to "welcome summer" and instructed Si Tuleideng and other officials to encourage farmers to work hard. Old customs make summer a traditional folk festival, called "Long Summer Festival".

The Han dynasty also followed this custom. The Book of Sacrifice in the Later Han Dynasty reads: "On the day of long summer, we welcome summer, and all the southern suburbs worship Chi Di, and the car flags and costumes are all red." The song "Zhu Ming" and the dance "Dancing with Wings". In the Song Dynasty, etiquette became more complicated. It was not until the Ming Dynasty that there was a "taste of new customs". In the Qing Dynasty, "Ji Sheng at the age of Emperor Jingdi" contained that "spring buds of rice noodles that are usually exposed outside are taken in long summer, fried into various fruit stacks with sugar noodles, and fed to each other".

It can be seen that the origin of the long summer and the custom activities of the long summer have a certain historical origin, which is a process of continuous development and inheritance.

Will the rainfall in the long summer increase significantly?

The rainfall in long summer will increase obviously. After the long summer, Jiangnan officially entered the rainy season, and the rainfall and rainy days increased significantly. Continuous rainfall not only caused wet damage to crops. It will also cause the prevalence of many diseases. The heading and flowering period of wheat is the most susceptible period to scab. If warm but rainy weather is expected in the future, close attention should be paid to spraying chemicals from the early flowering period to the full flowering period. Cotton in southern China often causes outbreaks of anthracnose, damping-off and other diseases under the weather conditions of continuous rain or sudden warming and cold, resulting in large-scale dead seedlings and lack of seedlings.

The custom of solar terms in long summer is obvious.

As long summer, the customs and characteristics of Long Summer are quite obvious, mainly due to the rich customs and eating habits in various places. In the past, when agriculture was dominant, it was also a busy season. In the misty and rainy south of the Yangtze River, Chang Xia wants to eat black rice. Black rice is not purple rice, but black glutinous rice soaked in the juice of black leaves. Steamed rice has the effect of relieving cough and calming the nerves, and is suitable for summer consumption. There are many allusions about black rice. According to the old saying, you still have to eat eggs in the long summer. After eating them, he can get fat for nothing. After eating broad beans, his eyes will light up, and he will be strong and not sick after eating meat. Because the heat in summer is a bigger test for everyone, eating these things in the long summer will have a good hope for the coming summer.

Agriculture is very busy.

Around the long summer, agriculture is busy, mainly because some areas will be in the season of early rice transplanting. Full-moon seedlings can be planted, but full-moon grass can't be planted. At this time, the temperature is still low. Immediately after planting seedlings, we should strengthen management, topdressing early, ploughing early, controlling pests early and promoting development early. Pay close attention to tail sweeping when sowing mid-season rice. At this time, the spring shoots of tea trees develop fastest. If we ignore them, tea leaves will get old. As the saying goes, "Grain Rain picks less, but doesn't pick it in the long summer", so we should concentrate our efforts and harvest it by surprise in batches. The dry atmosphere and dry soil in North China and Northwest China 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.
