The beginning of winter in 2021 is the first solar term in winter, and its last solar term is Frostfall, which belongs to autumn.Frostfall means that the climate is gradually getting colder, and it does not represent a real frost, so when the frost comes, we must pay attention to adding clothes.
Introduction to the Lidong solar term
Lidong is the nineteenth solar term in the twenty-four solar terms, and it is also the first of the six solar terms in winter.On the 8th or 8th, when the sun reaches 225 degrees of ecliptic longitude, it is the beginning of winter solar term.The beginning of winter means that anger begins to accumulate, and all things enter a state of recuperation and collection.The climate has also changed from dry and dry in autumn to rainy and cold winter.The ancient Chinese divided the beginning of winter into three phases:the water begins to freeze, the ground begins to freeze, and the pheasant enters the flood as a mirage.Before and after the beginning of winter, precipitation in most parts of China decreased significantly.The land in the Northeast is frozen, and agricultural and forestry crops are entering the wintering period; the "Three Autumns" in the Jianghuai region are coming to an end; Jiangnan is busy planting late winter wheat and transplanting rapeseed;
The solar term before the beginning of winter
Frostfall, the 18th solar term in the twenty-four solar terms, is regarded as frostfall when the sun reaches the ecliptic longitude 210 degrees from October 22 to 24 of the Gregorian calendar every year.Frostfall is the last solar term in autumn and is the transition from autumn to winter.Frostfall is not a falling frost, but a phenomenon in which the weather is cold and the earth will produce the first frost.The ancients of China divided frost into three phases:the jackal is sacrificed to the beast, the vegetation is yellow, and the sting is bent.In the frost season, the autumn harvest has already ended in most areas in the north, and even the cold-resistant green onions can no longer grow.In the south, it is the busy season of "Three Autumns".Single-season hybrid rice and late rice are harvested.Early wheat and rapeseed are planted; cotton is picked, cotton stubble is removed, and the land is tilled.
