What are the scenery in autumn?

Deciduous leaves, geese, chrysanthemums, osmanthus, crape myrtle.

First, fallen leaves

Fallen leaves are a natural phenomenon. Generally, in autumn, most deciduous plants and trees begin to shed their leaves, and the leaves turn yellow and curly, falling from the trees and dancing with the wind, which also means that after late autumn, winter is coming.

Second, geese

It is also a manifestation of herd instinct that geese are arranged in neat herringbone or zigzag. Because it is conducive to defending against enemy damage. Goose is always "captain" by experienced old geese, flying in front of the team. During the flight, the leading geese are physically exhausted, so they often exchange positions with other geese. Young birds and weak birds are mostly inserted in the middle of the team.

An experienced old goose always acts as a sentry when stopping by the water to look for aquatic plants. If the lone goose flies south, it is in danger of being eaten by the enemy. Wild geese fly back to the north to breed after the vernal equinox every year, and fly to the south for winter after the autumnal equinox.

Third, chrysanthemum

Chrysanthemum has strong adaptability, likes cold and is cold-resistant. The optimum growth temperature is 18-2 1℃, the highest is 32℃, and the lowest is 10℃. The low temperature tolerance limit of underground rhizomes is generally-10℃. The lowest night temperature at flowering stage is 17℃, and it can be reduced to 15- 13℃ at flowering stage (middle and late stage). I like plenty of sunshine, but I also tolerate shade a little. More resistant to dry, the most taboo waterlogging. I like sandy loam, which is located in Gao Qian, with deep soil layer, rich humus, loose fertility and good drainage.

It can grow in slightly acidic to neutral soil, and the pH value is 6.2-6.7. Avoid continuous cropping. Autumn chrysanthemum is a long-night plant, and its stems and leaves grow nutritionally under the long sunshine of 14.5 hours every day. Darkness of 12 hours per day and night temperature of 100 degrees Celsius are suitable for flower bud development. But different varieties have different reactions to sunlight.

Fourth, osmanthus fragrans

Osmanthus fragrans is one of the top ten traditional famous flowers in China. It is an excellent ornamental and practical garden tree, which has the functions of greening, beautification and fragrance. Osmanthus fragrans is necessary. Especially in the Mid-Autumn Festival when laurel trees are in full bloom and the night is quiet and full moon, it is refreshing to taste the fine wine and smell the fragrance of Chen.

In ancient Chinese poems about flowers, there are also a considerable number of poems about Guangxi. Since ancient times, it has been deeply loved by the people of China and regarded as a traditional famous flower.

Five, crape myrtle

Lagerstroemia indica, alias: itchy flower, itchy tree, purple flower, purple orchid, mosquito flower, Myrica rubra, zinnia, skinless tree. It is a dicotyledonous plant, deciduous shrub or small tree of Lysimachiaceae and Lagerstroemia, with a height of 7 meters.

Lagerstroemia indica has beautiful posture, smooth trunk and bright colors; When it blooms, it happens to be the season when there are few flowers in summer and autumn, and the flowering period is long. Therefore, it is known as "Hundred Days Red" and "Summer Blue and White Flowers Full", and it is a good bonsai for viewing flowers, stems and roots; Roots, bark, leaves and flowers can be used as medicine.
