When is the solar term in Xiao Man?

Xiaoman-refers to the summer crops with full seeds, but not yet mature, just small and not yet full. Every year on May 2 1 day of the Gregorian calendar, it is full.

Xiaoman is one of the 24 solar terms. On May 2 1 or 22 every year, when the sun reaches 60 yellow diameter, it is regarded as a small full. Twenty-four solar terms: "In mid-April, things are small and full." At this time, the seeds of summer sowing crops such as wheat in the north have begun to be full, but they are not yet mature, which is about the late stage of milk ripening, so it is called Xiaoman. At this time, we should pay close attention to the prevention and control of pests and diseases in wheat fields to prevent the attack of dry hot wind and sudden thunderstorm and gale. In the south, we should pay close attention to top dressing and weeding of rice, promote weed isolation, and harvest and dry summer grain in sunny days. After Xiaoman, high temperature weather above 35℃ began to appear from the south of the Yellow River to the middle and lower reaches of the Yangtze River, and relevant departments and units paid attention to heatstroke prevention and cooling. Disaster prevention in the "villain" season.

Xiaoman is the eighth of the 24 solar terms. "Nail spell is small and complete, everything is long to full. The wheat here is small and immature, hence the name. " This means that since Xiaoman, summer crops such as barley and winter wheat in the north have borne fruit, and the seeds are gradually full, but not yet mature, which is about the late stage of milk ripening, so it is called Xiaoman. This is a solar term indicating phenological changes. Agricultural proverbs in southern China give Xiaoman a new meaning: "Xiaoman is not satisfied, he thinks about it"; "Little people are full of discontent, regardless of mangoes." The word "full" is used to describe the amount of rain, and it is pointed out that if there is not enough water in the field when it is full, the ridge may crack and even rice cannot be planted when it is planted. Because "transplanting rice in long summer and planting rice in small fields" and "seedlings rushing to small fields and autumn fields", small fields are suitable for rice planting.

Judging from the climate characteristics, from Xiaoman solar term to the next Mang solar term, all parts of the country entered summer one after another, the temperature difference between north and south further narrowed, and precipitation further increased. At this time, we should pay close attention to the prevention and control of pests and diseases in wheat fields to prevent the attack of dry hot wind and sudden thunderstorm and gale. South China should pay close attention to rice topdressing and weeding, promote tillering, and pay close attention to summer grain harvesting and drying in sunny days. It is only after Xiaoman solar term that people really pay attention to meteorological problems. Xiaoman solar term is the prelude to harvest, the beginning of summer heat, and the time when diseases are easy to appear. It is suggested that people should have the health consciousness of "preventing before illness", and start from two aspects: strengthening healthy qi and preventing the invasion of pathogenic factors.
