Phenology (wù, hòu) refers to the long-term adaptation of organisms to the periodic changes of light, precipitation, temperature and other conditions, and the formation of the corresponding growth and development rhythm. This phenomenon is called phenology, which mainly refers to the growth, development and activities of animals and plants and the response of abiotic changes to seasons and climate.

Phenology refers to the periodic natural phenomenon that animals, plants, birds and weather change with seasons. Phenology is mainly a science that studies the periodic relationship between plants (including crops), animals and environmental conditions (climate, hydrology and soil conditions) in nature. Its purpose is to understand the changing law of natural seasonal phenomena and serve agricultural production and scientific research.

Phenology is also the process of talking about the moon, dew, wind, clouds, flowers and birds in a year. As far as plants are concerned, phenology refers to the phenomenon that plants germinate, sprout, spread leaves, bloom, bear fruit, fall leaves and sleep regularly with the seasonal changes of climate in a year, which is called phenology or phenology; The corresponding dynamic period of tree organs is called bioclimatic period, which is called phenological period for short.

Using phenology knowledge to guide the research of agricultural production has developed into a science called phenology in all countries of the world. Similar to climatology, phenology is a local science, which is to observe the passage of all seasons in various places and regions.

The difference is that climatology is to observe and record the changes of cold, warm, sunny and rainy weather in a certain place, such as windy on a certain day, rainy at a certain time, how cold it is in the morning, how hot it is in the afternoon and so on. , so as to infer its reasons and trends. Phenology is to record the growth and decline of plants, the communication and rearing of animals, such as willow green, peach blossom, swallow coming and other natural phenomena, so as to understand climate change and its influence on animals and plants.

Climate observation records the local weather at that time; Phenological observation records not only reflect the weather of the day, but also reflect the accumulation of weather in the past period. So phenology is sometimes called bioclimatology.
