What is the relationship between cold dew and production and life?

The relationship between cold dew 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.
