What effect does the seasonal change have on the growth of animals and plants?

The four seasons affect the morphology of plants, such as dead leaves in autumn, but the differences in temperature and light intensity brought by the four seasons will also have a day-and-night impact on plants. ?

Seasonal change covers many characteristics such as climate change and phenological change, such as spring germination, summer prosperity, autumn harvest and winter storage, which indicates the development process of things. ?

In spring, the qi of yin and yang begins to change, and everything germinates and grows with the rise of yang. Spring is the season for all things to grow and sow. The so-called "one year's plan lies in spring".

Everything is thriving in summer, which is the peak season for crop growth. The temperature rises, the weather is hot, storms are frequent, and everything flourishes. Summer is the most stormy season, often accompanied by strong winds and heavy rains.

In late autumn, the climate turns from hot to cold, and everything comes into being with cold and gradually falls. This is the season of alternating hot and cold. The most obvious change in autumn is that the leaves of vegetation change from lush green to yellow, leaves begin to fall and crops begin to mature.

In winter, yin and yang change, everything is hidden but not collected, and plants are angry and closed. After entering beginning of winter, it means that the dry climate with little rain in autumn has gradually passed and turned into a rainy and cold winter climate.

Geographical phenomena:

The traditional method of dividing the four seasons in China is based on the change of astronomical phenomena, with the "four stands" in the 24 solar terms as the starting point of the four seasons. At present, the four seasons are often divided according to the temperature change, which is based on the "average temperature" of modern scholar Zhang Bao _, and the division of the four seasons is based on this.

The seasons in mid-latitude areas are basically consistent with the "climate average temperature", while the temperature changes in low-latitude areas and near the polar regions are not obvious. In the southern hemisphere, the time of each season is just the opposite of that in the northern hemisphere. It is summer in the southern hemisphere and winter in the northern hemisphere; It is winter in the southern hemisphere and summer in the northern hemisphere.

Law of change:

From vernal equinox to summer solstice to autumnal equinox, the northern hemisphere is in summer and the southern hemisphere is in winter. During this period, the northern hemisphere has long days and short nights, while the southern hemisphere has short days and long nights. The north pole is in the extreme day and the south pole is in the extreme night; The height of the sun north of the Tropic of Cancer is always greater than the average, while the height of the sun south of the Tropic of Cancer is less than the average.

North of the Tropic of Cancer, the sun rises on the northeast horizon and sets on the northwest horizon. On the vernal equinox, the sun all over the world rises in the east and sets in the west.
