Rain is one of the twenty-four solar terms, four times a year, three months each in spring, summer, autumn and winter, and two solar terms each month, each with its own unique meaning. The meaning of Yu Shui is the beginning of rainfall and the gradual increase of rainfall. Yuan's Wu Cheng's work the moon order seventy-two wait set of interpretation said: in the first month, the sky is a water, spring is wood, but the wood must be water, so the spring followed by rain. And the east wind both thaw, it is scattered and for the rain to carry on. Rain, said two layers of meaning, one is the weather warming up, precipitation gradually increased, the second is in the form of precipitation, snow gradually less, rain gradually more. In the Yi Zhou Shu there is rain after the festival wild geese come grass and trees sprouting and other physical descriptions.
Rainy season means the beginning of rainfall, but the rainfall level is mostly light rain or drizzle. At this time in the northern hemisphere, the number of sunshine hours and intensity are increasing, the temperature is rising faster, the warm and humid air from the ocean becomes active and gradually advances north; at the same time, the cold air in the weakening trend is not willing to show weakness, and the warm air is frequently competing, forming rainfall.
There are three rainfall events: the first is the otter offering fish, the second is the arrival of geese, and the third is the sprouting of grass and trees. It is said that when the rainy season comes, the ice on the water melts and the otters start to catch fish. Otters like to bite the fish to death and put them on the shore in order, like a sacrifice, so there is otter sacrifice fish said. After five days of rain, geese start to fly back to the north from the south. After five more days, the grass and trees start to sprout as the yang energy in the earth rises. From then on, the earth gradually begins to show a scene of prosperity.
The rain festival, most of China's cold and snowy time has passed, the temperature has warmed up, which is conducive to the return of overwintering crops or growth, so we should pay close attention to the field management of overwintering crops, do a good job of seed selection, spring plowing, fertilization and other spring plowing, spring sowing preparations, in order to achieve the spring planting a grain of corn, autumn harvest of ten thousand seeds.
