Find two examples of phenological reports of spring news 20

It is a science that studies phenological phenomena such as the growth and decline of plants and the seasonal activities of animals, and analyzes and understands the cyclical changes of animals and plants in nature and environmental conditions, as well as the laws of natural seasonal changes.

Phenological phenomena are very extensive, and those natural phenomena in nature that are affected by the environment (climate, hydrology, soil) and occur in an annual cycle belong to phenological phenomena. It includes three aspects: (1) plant phenology, also known as crop phenology, such as various plant germination, leaf development, flowering, leaf discoloration, defoliation and other phenomena, and phenological phenomena in the growth period of crops.

2) Animal phenology, such as migratory birds, insects and other animal migration, initial song, final song, hibernation and other phenomena. (3) Various hydrological and meteorological phenomena, such as natural phenomena such as first frost, final frost, freezing, melting, first snow, and final snow.

The research object of phenology is to investigate the differences between north and south, east and west, vertical direction, and ancient and modern phenological phenomena. From the distribution of time and space, the relationship between climate change and animals and plants is expounded, and the laws are discovered, and these laws are used to study the changes of nature and guide production activities. For example, the phenological phenomenon is used to divide the four seasons, and the natural calendar is used to predict agricultural hours.

When making physical geographical divisions, phenology should also be used as the basis.

As early as 3,000 years ago in the early Western Zhou Dynasty, there was a monograph "Xia Xiaozheng" about phenology. Books such as Lü's Spring and Autumn in the Warring States Period, the Book of Bisheng in the Former Han Dynasty, the Hui Moon Decree in the Later Han Dynasty, and the Qi Min Yao Shu in the Northern Wei Dynasty all talk about the appropriate period for field operations such as sowing, ploughing, and harvesting, and most of them are based on natural phenology. The phenology of modern things was pioneered by the famous Chinese scientist Zhu Kezhen.

In his 1931 essay "On the Order of the Crescent Moon", Zhu Kezhen summarized the achievements of ancient Chinese phenology and advocated a new method for phenological observation. In 1961, the National Phenology Observation Network was established and phenological observation methods were formulated. In 1968, he published the book "Phenology".

In 1973, Zhu Kezhen's famous ** "Preliminary Research on Climate Change in China in the Past 5,000 Years" applied phenological methods to analyze climate change, which caused strong repercussions at home and abroad.

Phenology originated earlier abroad, and in Europe in the Hellenistic era, the Athenians formulated a lunar calendar that included phenology for one year. Japan has a history of 1,100 years since 812 A.D., when cherry blossoms bloomed. The countries in the world that have carried out phenological work well are Japan, Germany, the United States and the Soviet Union.

Plants germinate. The swallow returns.

Pink and willow green.

Phenological phenomena.

When the weather changes, everything on the ground, including animals, plants, etc., has to feel the effects of its change. Therefore, this special life phenomenon of animals and plants that occurs due to weather changes can help us to know the future changes of the weather in advance if they appear before our human perception of weather changes.

Ants move in, and it will rain. (Zhengding, Xingtai, Hebei).

The ants build a nest, and the water will rise. (Guangdong).

The ants build a defensive road, and there will be heavy rain. (Guangdong).

The urn wears a skirt, and it rains heavily. (Linzi, Shandong).

The water tank and stone pillars sweated, and it rained. (Guangdong).

The salt tank is still damp, and the rain is inevitable. (Yiwu, Zhejiang).

The cylinder wears the skirt, which is the phenomenon of too much water vapor in the air and condensing on the cylinder wall. The mountain wears a hat, which is a phenomenon in a frontal cyclone in which low clouds flood to the top of the mountain. The clouds move closer to the mountains, and due to the uplift of the terrain, the clouds often cover the summits.

The reason for the snake aisle is the same as that of the ants moving, because the air is humid and turbid, and they have to "go out".

Earthworms go on the road, and rain falls when they go out. (Guangdong).

Earthworms blocked the way, and the rain arrived in less than three days. (Guangdong).

Since earthworms do not have specialized respiratory organs, respiration is carried out by **. The oxygen in the soil is first dissolved in the mucus on the surface of the soil, and then seeps into the capillaries. When the soil is too wet, there is less air in the soil, which affects the normal "breathing" of earthworms.

Therefore, when it is about to rain or after rain, it is common to see earthworms crawling out of the ground.

Grasshoppers come out early, and fish come out of waterlogging, and they all say that grasshoppers are fish roe. (Cangxian County, Hebei).

The grasshopper is a locust, its eggs are born in the soil, and when the land is dry, it is easy to breed. Fish eggs are born in water, and large water is suitable for the growth of fish. When the soil is too wet, there is less air in the soil, which affects the normal "breathing" of earthworms.

Therefore, when it is about to rain or after rain, it is common to see earthworms crawling out of the ground.

Grasshoppers are born in drought and fish are fished in waterlogging, and grasshoppers are said to be fish roe. (Cangxian County, Hebei).

Grasshoppers are locusts, their eggs are born in the soil, and when the land is dry, it is easy to reproduce. The oviparous eggs are born in the water, and the large water is suitable for the growth of fish.

Dragonflies fly low, either in the wind or in the rain. (Yiwu, Zhejiang).

Before the rain, the air humidity is high, and the wings of flies, mosquitoes and other small insects are stained with water, which increases the weight and cannot fly high, and dragonflies also fly low and hover in order to catch these small insects.

The swallow flies low, and it is set to rain. (Hebei).

Before the rain, the wind was strong and the agitation was intense, so the swallows could only fly low. In addition, before the rain, insects do not fly high, so the chaffinches that hunt insects have to fly low in order to get food.

The chickens return to the cage early, and the weather is fine; The chickens are late to return to the cage, and heavy rain is coming. (Guangdong).

The chicken likes to be dry, the moisture is heavy before the rain, and the chicken coop is particularly wet and stuffy, so it is reluctant to go into the cage early.

The sky is sunny for spiders. (Yiwu, Zhejiang, Wuxi, Jiangsu).

Spiders make a living by catching small flying insects by building webs, and they are particularly sensitive to air humidity. Cloudy, the air is humid and heavy, the spiders are damp and have poor stickiness, and it is difficult to catch small insects. When the weather improves, the humidity of the air gradually decreases, and the spiders begin to move, busily adding silk and webs to catch small flying insects.

The trees shed their leaves in autumn, and the harvest is about to begin.

When the swallows fly, it is a sign that spring is coming.

The peach blossoms are blooming, hinting at planting millet quickly.

Ants move in, and it will rain.

The ants build a nest, and the water will rise.

The ants build a defensive road, and there will be heavy rain.

The urn wears a skirt, and it rains heavily.

The water tank and stone pillars sweated, and it rained.

The salt tank is still damp, and the rain is inevitable.

Earthworms go on the road, and rain falls when they go out.

Grasshoppers come out early, and fish come out of waterlogging, and they all say that grasshoppers are fish roe.

The wild geese flying north indicate that autumn has arrived, and the moving of ants indicates that it is about to rain, and the name is known to indicate the hot summer season.

For example, winter bud germination, leaf pulling, flowering, fruiting, and defoliation of plants; The dormancy, recovery, initiation, mating, breeding, moulting, migration, etc., of animals are closely related to the season. Abiotic phenomena, such as the first frost, the beginning of snow, thawing, etc., are also known as phenological deficits.

In the natural environment, various macroscopic natural phenomena that occur periodically are called phenological phenomena. Flowers bloom and fall, leaves green and leaves yellow, etc. are all phenological phenomena.

Because it is generally accepted that the temperature in the coastal areas is warmer than in the interior, in fact, the temperature in the coastal areas is warmer than in the inland areas.

The cold spring is a phenomenon that is relatively unfamiliar to readers. Just one example of the reader's chance, according to two, there is no doubt about it.
