Autumn has come. What changes have taken place in the lives of animals, plants and people?

When autumn comes, animals begin to spend the winter, plants begin to wither, and humans begin to add clothes to keep warm.

Autumn is the harvest season, and many plants mature in autumn. In autumn, in nature, the qi of yin and yang begins to change, the yang is gradually declining, the yin is gradually flourishing, the climate turns from hot to cold, and everything is born with cold and gradually declines. This is the season of alternating hot and cold. With the gradual decline of temperature, the leaves of many deciduous perennial plants will gradually change color, wither and fall off, leaving only branches for winter.

Panicum miliaceum will come to the end of his life, wither and die. Seasonal variation covers many aspects of climate characteristics, and it is not accurate to judge autumn only by temperature. The most obvious change in autumn is that the leaves of vegetation change from lush green to yellow, and the leaves begin to fall and the crops begin to mature.

Extended data:

Entering autumn means that rainfall and storms tend to decrease or decrease, and everything in nature begins to mature from lush. The beginning of autumn does not mean the end of hot weather. As the saying goes, "the summer heat is in dog days", according to the calculation method of "dog days", beginning of autumn is often in dog days until the summer heat, so the weather is still very hot in early autumn, and it will generally get cold after the Millennium solar terms.

The watershed of summer heat is in autumn, not at the turn of summer and autumn. The climate in autumn is divided into two stages, the early autumn is sultry, and the climate tends to be dry and cool after the Mid-Autumn Festival. Generally speaking, in autumn, the height angle of the sun gradually decreases, and the temperature gradually decreases from heat; The autumn wind is cool, the summer heat is gone, the fruits are covered with branches, and the fields are golden.
