What is the relationship between the first frost and production and life?

The relationship between the first frost and production and life is:

The white dew is a mystery, the autumn equinox rice is beautiful, the cold dew is green rice, and the first frost falls together. This is slang for describing the relationship between rice maturity and solar terms in Jiangnan area of China. In the Millennium season, rice is in its flowering period (with small white flowers) and looks white. By the autumnal equinox, the rice has been filled and firm (delicate), and by the cold dew season, the rice is basically mature, and the seeds turn from green to yellow. As soon as we reach the first frost, all the rice will be harvested. (deleted).

"One grain, seven loads of water." This slang means that rice needs to consume a lot of water during its growth. In the past, it was very laborious to irrigate rice with human or animal power. This slang requires people to cherish food and respect farmers' labor.

From the perspective of agricultural production, this means that many crops have to start "frost prevention" and related crop cultivation has entered a new stage.

The autumn harvest has been completed in most parts of the north, and even the cold-resistant onions can't grow any longer, because "the first frost can't support onions, and the longer they grow, the more empty they become." In the south, it is the busy season in Sanqiu, harvesting single-season hybrid rice and late rice, planting early-crop wheat, planting early-crop rape, picking cotton, pulling cotton stalks and ploughing. "The straw is pulled all over the floor, and there will be fewer insect pests and diseases in the future."

Take back the straw and stubble in time after harvest, because there are many wintering eggs and germs hidden there. The Chinese cabbage in North China is about to be harvested, so it is necessary to strengthen the management of the early frost season in the later period. Most parts of China have entered the dry season, so we should attach great importance to forest protection and fire prevention.

The origin of the first frost solar terms:

Every year around Gregorian calendar 10 year 10, when the sun reaches the longitude of 2 10 degrees, it is the first frost in the 24 solar terms. The first frost is the last solar term in autumn, which is the transition from autumn to winter. There is a lot of heat dissipation on the ground in autumn, and the temperature suddenly drops below 0 degrees. Water vapor in the air directly condenses on the ground or plants to form fine ice needles, and some become hexagonal frost flowers, which are white and loose in structure.

"First frost" means that the weather is getting colder and the dew condenses into frost. In ancient China, the first frost was divided into three periods: first, jackals sacrificed animals; second, yellow vegetation; third, stinging insects. The jackals began to catch their prey, offering sacrifices to heaven to repay their kindness, paving the way for offering sacrifices to autumn gold. The leaves on the earth withered and fell, and the stinging insects hung their heads in the holes and went into hibernation.

Folklore in The First Frost:

In some parts of China, red persimmons should be eaten in the first frost season. In the eyes of local people, it can not only keep out the cold and keep warm, but also nourish the bones and muscles. This is a good first frost food. The old man in Quanzhou said that the first frost eats persimmons: the first frost eats persimmons, and the nose will not flow. In some places, the explanation of this custom is that the first frost will eat shuttlecock on this day, otherwise his lips will crack all winter. At this time, people living in rural areas will climb tall persimmon trees and pick some bright and sweet persimmons to eat.
