is different from the simple differentiation of four seasons in foreign countries. In ancient China, farmers divided a year into 24 solar terms to correspond to different stages of farming. Xiaoman is also one of the 24 solar terms. Let's take a look at the origin and climate characteristics of Xiaoman in this issue of the old yellow calendar.
the origin of the Xiaoman solar term "the collection solution of the seventy-two seasons of the month": "in the middle of April, the things that are Xiaoman cause things to be small and full here." at this time, the grains of summer crops such as wheat in northern China have begun to be full, but they have not yet matured, which is about the late stage of milk ripening, so they are called Xiaoman. The Southern Agricultural proverb gives Xiaoman a new meaning: "Xiaoman is dissatisfied and breaks the ridge of the field"; "If Xiaoman is dissatisfied, grain in ear doesn't care". "Full" is used to describe the surplus and shortage of rain. It is pointed out that if the field is not full of water during Xiaoman, the ridge may be dry and cracked, and riceand
cannot be planted even during grain in ear. The climate characteristics of Xiaomanand
in the southern region "Xiaoman and damanjiang" reflect the climate characteristics of heavy rainfall in this region. "Xiaoman", as the saying goes, "Xiaoman at the beginning of summer, the rivers are easy to be full", which reflects the climatic characteristics of heavy rainfall and heavy rainfall in South China at this time. At the same time, with the Dragon Boat Festival approaching, Guangdong has also entered the annual "dragon boat water" period. When the dragon boat water comes, the water level of the river rises rapidly, providing good site conditions for raking the dragon boat.and
in the middle and lower reaches of the Yangtze River, "there is no rain in the small full, and there is no water in the ear seed". For the middle and lower reaches of the Yangtze River, if there is less rain at this stage, it may be that the subtropical high in the Pacific is weak and located to the south, which means that there may be less precipitation in Huangmei season. Therefore, there is a folk saying that "if there is no shortage of plums, there are few yellow plums"; "Little full without rain, no water in ear seeds".and
in the middle and lower reaches of the Yellow River, when "Xiaoman is dissatisfied, wheat has a risk" is the Xiaoman solar term, such a saying is still circulating in the middle and lower reaches of the Yellow River and other regions. The so-called "one risk" means that wheat has just entered the milk ripening stage at this time, and is very vulnerable to dry hot wind, resulting in insufficient grain filling and shrinkage of wheat seeds. There are many ways to prevent dry hot wind, such as building shelter belts and spraying chemicals, which are very effective measures.and
