In the twilight of spring, the flowers wither. Peonies are in full bloom and are sought after. But there is a kind of flower that is disgusting and has been given a cold reception. It can be found almost everywhere on the streets of the city, and it is the heather. A fishy smell, 84 disinfectant, "assassin in flowers", is the consensus of the general public on it.
The reporter of Dahe.com learned from the Zhengzhou City Management Department that heather, like the familiar peach and plum pear, belongs to the big family of Rosaceae. In ancient documents, the ancients chanted about it, and some people planted it in the courtyard as one of the greening plants.
Although heather is "smelly", it is a powerful tool in urban greening, an anti-smog artifact that can purify the environment, and an easily obtained variety that balances biodiversity. The flowering period of heather is relatively short, so it is recommended that you do not "take the tree by taste".
【Phenomenon】Heather blooms, and in a word, "Nan" is exhausted
Recently, Zhengzhou citizens may have noticed that the familiar "fishy smell" wafted from the street corner amusement parks and road squares. Following the taste, I saw a heather bush, on which white fine flowers had bloomed. Heather blooms in clusters, and it looks like a giant cauliflower from a distance, but its smell is annoying, and it has a cold reception that distinguishes it from other flowers.
For the taste of heather, the public has many praises and disapprovals. Some people believe that heather has a fishy smell, similar to the smell of a human bodily fluid. Some citizens believe that heather is similar to the 84 disinfectant used at home, and when it reaches a strong place, it will choke people's heads and make people dizzy.
The special smell emitted by heather flowers makes people say "nan" in one word, and most citizens can only take a detour. Some citizens said that the smell of this flower is very stinky, and it is very uncomfortable to smell it.
Zhang Jingjing, head of the Park and Green Space Management Section of the Greening Center of the Jinshui District Urban Administration Bureau of Zhengzhou City, said that the reason why the smell of heather is unpleasant is due to a wonderful oxidation reaction. The smell of heather is mainly caused by the oxidation of arginine, an amino acid compound that releases this special smell when it meets oxygen.
"But rest assured, although the smell of heather is not very good, it has no effect on the human body. Zhang Jingjing said.
【Record】Heather blooms, once very poetic
Compared with peach blossoms, plum blossoms, apricot blossoms, begonia flowers, peony flowers and other common flowers in spring, heather is obviously the kind of flower that is not welcome. But in the records of the ancients, the heather was also full of poetry.
Chen Yuanlong of the Qing Dynasty quoted the "General Theory of Gewu" in "Gezhi Jingyuan Heather", "Heather leaves are like pipa, there are small thorns, they do not wither in winter, white flowers in spring, fine red and solid in autumn, many people transplant between the courts, the shade is lovely, and the sun is not permeable." It can be seen that the heather is evergreen in all seasons, spring and autumn, some people plant it in the courtyard, the branches and leaves are dense, and it can also shade and enjoy the coolness.
The seventy-second volume of Wang Hao's "Guangqun Fangpu" in the Qing Dynasty made a detailed record of heather. Wang Hao quoted "Southern Records" and said, "The heather tree, wild, February flowers, is like swallow eggs, ripe in July and August", according to the records, the fruit of heather is edible. "Guangqun Fangpu" records: "Heather flowers bloom in February. In winter, there are two leaves for flower buds, the buds are open, there are more than 15 flowers, the size is like a tsubaki flower, very finely broken. Each bud is about a large bounce and becomes a ball. One flower has six leaves, one flower has seven or eight balls, pale white-green, and the end of the leaves is slightly red. The flowers are blooming, and the stamens are full of flowers, but the stamens are seen, but the flowers are not seen. The flowers are just now, and last year's green leaves have fallen off and new leaves are gradually growing. ”
Heather is also called the upright tree, which is related to the allusion of Yang Guifei of Tang Xuanzong. "Guangqun Fangpu" quoted "Taizhen Biography" recorded, "Go up to Ma Wei and go to Fufeng Road." There are flowers on the side of the road, and the temple side sees the reunion of the heather tree, and loves to play, because it is called a righteous tree, and the cover is thoughtful." The late Tang Dynasty poet Zhao Yi has a poem "Song of the Spring Tree", which is the story of Ma Weipo.
When it comes to loving flowers, Bai Juyi will not be absent, he wrote in "The Heather Tree", "The spring buds are fine and a thousand lamps are burning, and the summer rui is thick with a hundred and incense." Seeing that there is no such tree in the upper forest, only teach the peach and willow to occupy the year", it is also singing unevenly for the heather.
【Function】Anti-haze artifact, greening cadre
In fact, at this time of year, some citizens want to ask, the taste of heather flowers dare not compliment, a word "Nan" is exhausted, why do the landscaping urban management departments plant them in a large area?
What everyone doesn't know is that although the heather is smelly, it is a capable leader in urban greening. Zhang Jingjing said that although the smell is unpleasant, from the perspective of urban greening, heather has many advantages. Heather is evergreen in all seasons, has the effect of anti-smoke, absorption of automobile exhaust, mosquito repellent, dust reduction and dilution of toxic gases, and is known as an anti-haze artifact, which can play a role in purifying the environment.
At the same time, heather has a high survival rate and is easy to maintain, and they also play a positive role in balancing urban biodiversity. If the above advantages are combined, there are not many plants in landscaping that can replace heather for the time being.
The reporter of Dahe.com learned that the heather has strong ornamentality, evergreen in all seasons, flowers and leaves in spring, and fruits in autumn. Like the willow flocculent in late spring every year, heather flowering is also a means for plants to thrive, and when enjoying the shade they provide, the general public should also have a tolerant heart and look at willow and heather flowering more comprehensively.
In addition, the flowering period of heather flowers is only 10 to 20 days, and when the flowering period is over, the public will no longer be troubled by the smell of heather.
