What is the national flower of Ukraine (the name of the national flower officially announced by Ukraine)

Today, the situation in Ukraine affects people around the world, and PANTONE, an authoritative color research organization that has always been very concerned about fashion trends and social issues, speaks out with colors, calls for peace and fights for war in its own way. People prayed to redefine the two colors of the Ukrainian flag and give them the names of "freedom" and "energy", namely "FreedomBlue" (#005BBB) and "EnergizingYellow" (#FFD500).

These two bright colors echo the sunflower, the national flower of Ukraine. Seeing these two colors is like seeing the sunflower blooming in the blue sky and sunshine, looking forward to a bright and positive future. , the power of facing the sun arises spontaneously.

I recently went to the Sunflower Base, and someone asked: The sunflower follows the sun, so how does it turn back at night?

p>

How does it change? It seems to be mentioned in primary school textbooks, or there is an explanation of plant physiology, but many people have forgotten it. This article will briefly talk about the past and present lives of sunflowers

Sunflower, scientific name Helianthusannuus L., is an annual herb of the Compositae family.

Because the front of the sunflower disk rotates toward the sun, it is also known as sunflower, sunflower, sunflower, sunflower, and sunflower. , sunflower, sunflower, sunflower, etc., and because sunflower is a tall and large-flowered Asteraceae plant, it is also called zhizhangju and passionflower.

Sunflower is native to 30°~. In southern North America and northern Mexico at 40°N, according to research, sunflowers were introduced to my country in the mid-Ming Dynasty and have a long history of cultivation.

Sunflowers were first mentioned as "Zike" in the late Qing Dynasty. "Oil extraction", it can be seen that sunflowers were first planted as small oil crops. Later, through long-term flower optimizing and nurturing, large areas of sunflowers were ornamental.

A brief look at the expansion of sunflower cultivation

"Fujun Agricultural Products Examination" states that sunflowers can be planted "alongside walls and fields", which shows that sunflowers have begun to be grown sporadically in my country as ornamental plants and small oil crops.

The "Hulan County Chronicle" of Heilongjiang in the 19th year of the Republic of China (1930) recorded: "The seeds of sunflowers are edible. There are people who plant them per acre." This shows that large-scale cultivation of sunflowers began in the Northeast in 1930.

In the early days, sunflower planting areas were mainly distributed in Northeast, North China, and Northwest China

In the 1960s and 1970s, the Northeast region had the largest planting area

After the 1980s , the center of sunflower cultivation and production began to move westward, and Inner Mongolia, Xinjiang and Gansu became the main areas for the increase in sunflower planting area in my country.

In the late 1980s, small batch planting of ornamental sunflowers began

Before large-scale planting, sunflowers were imported from China and the market was monopolized by Europeans. After decades of hard work, , finally achieved sunflower freedom!

Sunflowers can be seen almost all year round. The best seasons are summer and winter, when the sky is cloudless and the bright colors of sunflowers warm people's hearts (usually from January to April or September to October Sowing every month, blooming 60-70 days after sowing), cut flower sunflowers have been supplied throughout the year, with various varieties and rich colors.

This is the charm of ornamental sunflowers, but also because ornamental sunflower seeds are smaller and have poor seed setting rate, it is very difficult to It is rarely used for food, and the seeds on the market are also favored to be imported.

Sunflowers are very popular with their colorful colors and huge flower plates. They are often used in various festivals, anniversaries, banquets, etc.

So how do sunflowers "turn back" at night?

Sunflowers have strong phototaxis, so they will always grow in the direction of light. As long as there is light, they will have the motivation to grow and bloom until they wither and wither.

Since it is heading towards a place with light, it will keep turning, adjusting and turning slowly and little by little. It is not the sunflower in Plants vs. Zombies, and it will not turn around suddenly. It would only turn around if it really turned around. Is it really scary?

That’s it for this issue’s sunflower talk. I wish your mood will be as bright as a sunflower every day!
