What day is Deciduous Day? What day is the beginning of autumn today?

The Fallen Leaves Festival is a traditional festival in the country of trees.

Also known as the Festival of Lights, it is the 49th day after the autumn solstice every year, and it is also said that it is 49 days after the beginning of autumn.

Well, the time to get the deciduous festival is like this, generally from the day the ginkgo biloba leaves fall d, it is called the deciduous festival, because generally when the ginkgo biloba leaves fall to the ground. It's late autumn, so it's usually at this time, and it's customary to treat it as a deciduous knot.

Original song of China's ** Academy.

Dreams are like that blue sky.

Innocent smile.

Warm each other's first meeting.

Gaze at the starry sky.

Shooting stars streaked by.

Bear witness to the wishes we have made.

How many years in the blink of an eye.

There are too many memories of that picture.

Keep reproducing the rain of fallen leaves in my dreams.

I haven't heard of the Fallen Leaves Festival yet, but I think it's going to be fun, and I feel good when I hear the name.

Sister Fallen Leaves: What day is it, I haven't heard of it specifically, but I think he should be in the middle of autumn, in the late autumn.

The beginning of autumn in 2016 is 08/07 09:52:58 The beginning of autumn is the 13th solar term in the 24 solar terms, and it is the end of the month of the Ganzhi calendar and the beginning of the Shen month; The time is around the first day of the seventh month of the lunar calendar every year (between August 7 and 9 of the Gregorian calendar).

"Autumn" means that the summer has gone away and the cool has come, which means the beginning of autumn. At the beginning of autumn, the sycamore tree begins to lose its leaves, so there is an idiom that "falling leaves know autumn". From a literal point of view, the character "autumn" is composed of the word grass and fire, which means that the grain is ripe.

Autumn is the transitional season when the weather turns from hot to cool, and then from cool to cold, and the beginning of autumn is the first solar term of autumn.

In ancient China, the beginning of autumn was divided into three phases: "one waits for the cool breeze to arrive; The second candidate is Bai Lusheng; Three chilling cicadas. ”

Cool breeze: People feel cool when the wind blows, and the wind at this time is different from the hot wind in the summer.

White dew falls: There will be fog on the earth in the morning.

Cicadas: In autumn, the cicadas that chirp in the shade also begin to chirp.

The first thing that comes with the "beginning of autumn" is the change in the weather. From this day on, the sky is high and cool, the moon is bright and the wind is clear, and the temperature gradually drops, as the proverb says: "The cool breeze arrives on the day of the beginning of autumn", "The autumn is established in the morning, and the evening is cool".

However, there is a big difference between the morning and evening of the "beginning of autumn", the so-called "early autumn is cold, late autumn is hot and dead cow", that is, people should not be blindly optimistic about the "beginning of autumn", sometimes "after the beginning of autumn, there is still a '(autumn) tiger" in one". In fact, the biggest magic weapon for cooling down in the "beginning of autumn" is rain, "a rain before and after autumn, and a wind before and after the white dew", which is the conclusion drawn by people's long-term observation.

Why do trees lose their leaves in autumn?

Because autumn means the advent of winter, trees need to be dormant in order to protect themselves, and the overwintering dormant trees themselves also need nutrients, in order to regulate their own homeostasis, many trees need to fall leaves, reduce the loss of water's nutrients, and store energy until the conditions are suitable before germinating;Some trees such as pines and cypresses can remain evergreen because their leaves are like needle tips and have very little water loss.

People often use the phrase "autumn wind sweeping away the leaves" to describe the autumn scenery in temperate regions. When autumn arrives, the leaves of broad-leaved trees such as poplars and locust trees gradually age, and with the autumn wind, the yellow leaves quietly fall off the bridge. You may feel sorry for the falling leaves, but have you ever thought that falling leaves are precisely the self-protection of trees?

When it was cold, people lit stoves and put on cotton clothes. But what about the trees? They can only survive the winter safely by stripping their leaves to minimize water transpiration.

Otherwise, it is already difficult for the roots to absorb water, but the transpiration of the leaves continues as usual. Think about it, what kind of regret awaits the trees but death?

The petioles originally grew stiffly on the branches. In autumn, as the temperature drops, several layers of fragile parenchyma cells form at the base of the petioles. Because these cells are easily separated from each other, they are called delamination.

When the separation layer is formed, it breaks if it is blown by a slight breeze, and the leaves fall down.

Leaves are broad-leaved trees in temperate regions, reducing transpiration and preparing for a safe winter.

It also has a lot to do with the abscisic acid contained in trees.

It seems that according to the 24 solar terms, it should be However, if the climate changes, it may cause early or late arrival.

Generally speaking, it is after frost, and some plants lose their leaves in large quantities after the water freezes outside.

1. The whole annual growth cycle refers to the morphological and physiological changes that the growth and development of plants show adaptation to the external environmental factors with climate change every year, and show a certain regularity. During the annual growth cycle, the period of morphological change of plant organs that adapt to seasonal climate change is called the phonological period. There were obvious differences in the phenological period of different horticultural plant species and varieties.

Environmental conditions and cultivation techniques can also alter or affect the phenological period. In production, it is often used to regulate and control the growth and development of plants, and develop in the direction that people expect.

The annual growth cycle changes in deciduous fruit trees and deciduous ornamental trees are clearly divided into growth period and dormant period. Evergreen trees do not have a significant dormant period during their annual growth cycle. 1-year-old plants only have a growing period. In between, some of the 2-year-olds have a significant dormancy period, while others do not.

Taking perennial woody plants as an example, the characteristics of the annual growth cycle of horticultural plants are illustrated.

1) Growth period

The growth period refers to the period when all parts of the plant organs show significant morphological characteristics and physiological functions. Deciduous trees begin to bud in spring and end in autumn. It mainly includes the phenological stages of budding, vegetative growth, flowering and fruit setting, fruit development and ripening, flower bud differentiation and defoliation.

However, evergreen trees can be carried out at the same time due to flowering, vegetative growth, flower bud differentiation and fruit development, and the shedding of old leaves mostly occurs after new leaves, and new shoots can germinate many times within one year. Some trees can have multiple flower bud differentiation and multiple flowering and fruiting, and their phenological period is more complicated. However, the order of the annual growth cycle of the same plant is basically unchanged, and the early and late occurrence of each phenological stage is affected by climatic conditions, especially temperature.

2) dormant period

The dormant period refers to the period when the life activity of the buds, seeds or other organs of the plant is weak and the growth and development performance is stagnant. The dormant organs of plants are mainly seeds and buds. For example, apples, peaches, chestnuts, peonies and other seeds must be treated with low temperature layering to reduce the inhibition of germination substances in the seed coat and endosperm before germination.

On the other hand, bud dormancy includes dormancy during overwintering of deciduous trees, and dormancy of bulbs and tubers such as garlic and potatoes.

Dormancy of deciduous fruit trees: The dormancy period of deciduous fruit trees usually refers to the period after the fall of leaves in autumn and before bud break in the following spring. The length of the dormancy period varies depending on the species, species, environment of origin, and local natural climatic conditions.

Generally, plants native to the cold zone have a long dormancy period and require low temperatures. In the local climatic conditions, the temperature is the most important, which directly affects the length of the dormancy period. In general, the lower the temperature, the shorter the sleep time; The higher the temperature, the longer the sleep time.

The low temperatures required for deciduous trees are generally as follows:

Dormancy of tubers and bulbs: The dormancy of potatoes actually begins at the moment when the tubers begin to expand, but the dormancy period is calculated as the number of days from harvest to bud germination, which is natural dormancy, and can be dormant for 1-3 months at a temperature of about 25. After the end of natural dormancy, until sowing, it is still necessary to continue to be forced to dormant in o14.

The dormancy of onions, garlic, etc., is similar to that of potatoes.

Deciduous plants are mainly based on weather factors.

Ginkgo trees usually begin to shed their leaves in November and start to sprout new leaves in May of the following year.

Ginkgo biloba (scientific name: ginkgobilobal.).) is a deciduous tree of the family Ginkgo and Ginkgo biloba.

Ginkgo biloba appeared hundreds of millions of years ago, is the oldest relict plant of gymnosperms left after the Quaternary glacial movement, the surviving ginkgo biloba is scarce and scattered, hundreds of years old trees are rare, and all other plants of the same class have been extinct, so ginkgo biloba has the reputation of living fossils. There are 26 varieties and varieties: yellow-leaved ginkgo, tower-shaped ginkgo, split ginkgo, weeping ginkgo, spotted leaf ginkgo and so on.

Ginkgo biloba is also known as the ginkgo tree.

Gongsun tree and duck foot tree are rare tree species left by the Mesozoic Era, which are special products of China. Ginkgo biloba.

It usually blooms in April, turns yellow in October, falls in November, and begins to grow tender new leaf buds in May. It grows slowly, has an extremely long lifespan, and under natural conditions, it goes from planting to bearing ginkgo biloba.

It will take more than twenty years, forty years to produce a large number of results. The tree posture is tall and straight, the leaves are fan-shaped, the trunk is straight, the posture is beautiful, the spring and summer are verdant, and the late autumn is golden, which is an ideal street tree species.

3.Hubei Anlu Ginkgo Valley.

Anlu City, Hubei Province.

Wang Yizhen Town in the west, located at the southern foot of Dahong Mountain, is known as the "hometown of ginkgo" in the country. Anlu Ginkgo Valley Garden is one of the two existing natural state ancient ginkgo communities in China, and it is the Central Plains region.

Rare natural ancient ginkgo community. It covers an area of 60 square kilometers.

There are 48 ancient ginkgo trees over 1,000 years old, 1,486 trees over 500 years old, 4,368 trees over 100 years old, 5 natural garden groups, and 36 ancient ginkgo scenic spots with more than 25 trees in a row. The ancient ginkgo biloba community in Qianchong is not only rare in the country in terms of number and age, but also has different tree shapes, including husband and wife trees, couple trees, descendant trees, mother and child trees, etc., which are of great ornamental value.

The mystery - Shen Monkey Interpretation - Autumn falls "leaves" - autumn is autumn. The leaves have fallen completely, and the last leaf clump has also fallen and seeped, leaving only the bare trunk and branches "ten". The tenth zodiac sign is - Shen Monkey Posture Number.

Summary. Autumn is the time of autumn, from September to November. "Golden Autumn" means "autumn".

In ancient times, the Yin-Yang family also used the five elements of wood, fire, metal, and water to supervise one of the four seasons. Jin is in charge of autumn, and it can be seen that "gold" is autumn. Therefore, "golden autumn" is a table juxtaposition of words, which means "autumn".

In the same way, the "golden wind" in "Golden Wind Sending Cool" is also "autumn wind".

Autumn is from September to November, and astronomy is from the autumn equinox to the winter solstice. Autumn is considered autumn when the five-day average temperature stabilizes below 22 degrees Celsius after the heat has passed, and autumn ends when it falls below 10 degrees Celsius. The most noticeable change in the natural landscape is the trees, with the city sweeping away a large number of fallen leaves, and the mountainous areas flocking to the autumn leaves.
