What are the characteristics of solar terms in Grain Rain and Grain Rain?
2. After the solar term in Grain Rain, the rainfall increased, and the rain gave birth to hundreds of valleys. With sufficient and timely rainfall, cereal crops thrive. In the south where the grain is abundant, poplars fall out of flowers, willows fall out of flowers, cuckoos cry at night, peonies are in full bloom and cherries are ripe. The natural scenery tells people that it is late spring. At this time, the temperature in the south rises rapidly. Generally, in late April, except for parts of northern and western South China, the average temperature has reached 20℃ to 22℃, which is more than 2℃ higher than that in mid-April. High temperatures above 30℃ often occur in eastern South China for a day or two, which makes people feel very hot. Low-altitude valley areas are used to enter summer. The climate characteristics of high temperature in south China in spring are beneficial to the early cropping cultivation measures in Da Chun. The suitable planting temperature of Polygonum cuspidatum is 65438 08℃ to 22℃, which can be satisfied at this time. The experience in the old arid areas in southern China has proved that planting Osmunda japonica early in Grain Rain can seal vine leaves before summer drought, enhance drought resistance and achieve high and stable yield.
3. "Before Grain Rain, cotton was well planted." There is a saying: "Grain Rain doesn't plant flowers, and its heart is like a crab crawling." Since ancient times, cotton farmers have regarded Grain Rain Festival as an indicator of cotton planting, compiled proverbs and passed them down from generation to generation.
4. The weather proverbs of Grain Rain Festival mostly revolve around the center of rain but no rain, such as "Grain Rain is gloomy, it rains in summer", "Grain Rain rains, and there is no dry soil for forty-five days" and so on. There are also solar terms in Grain Rain, such as high temperature and frequent rainy days, which will cause the occurrence and prevalence of pests and diseases of wheat. The vast rural areas should do a good job in the prevention and control of wheat diseases and insect pests according to the weather changes.
