An alien species native to Canada, a yellow flower invasion, was found in our neighboring county of Nanhua County, Chuxiong Prefecture, the discovery process was discovered by accident, on December 7, 2021, Mr. Liu, a citizen of Nanhua County, sent his own picture in the WeChat group, saying that he found an exotic species in Canada, a yellow flower, which attracted people's attention.
Mr. Liu, a citizen of South China, went to the mountain last year to look for crane grass, and found a strange plant, very bright and beautiful, and thought it was a newly introduced flower, because there was only one plant at that time, so I was not sure at the time, and I thought that there was no impact on the surrounding organisms
But the development of things, is not like this, is that when he went to see again this year, he found that the plant has spread a large piece, the plant that grows out is 50 to 100 square meters, Mr. Liu feels very strange, just check it on the Internet, the preliminary confirmation is that the Canadian outside species "a yellow flower", this species, I look very bright, if it is a piece, it feels very good, but after the seed matures, the spread is very rapid.
The alien species "Canada a yellow flower" also known as the yellow warbler, unicorn grass, is an herbaceous plant, its root system is relatively long, can absorb sufficient nutrients, so its plant can grow to about 3 meters, the damage to the soil is very large, the place where it grows, it can be said that it is difficult to grow grass, so he also has an alias called "Overlord Flower", ecological killer and other names, for the surrounding biodiversity, constitutes a serious threat, according to the rural saying is called, as long as the yellow flower is over, the surrounding can be said to be grassy.
Its principle is like an aircraft grass that has invaded our country for a long time, spreading rapidly, spreading widely, as long as there is a place where the seeds have fallen, it can closely grow a yellow flower, other plants can not grow, which seriously affects the balance of ecology, just like Mr. Liu found, last year only found a plant, this year can grow 50 to 100 square meters of yellow flowers, which can imagine how much impact on the ecology.
After Mr. Liu found this large piece of yellow flowers, the relevant departments have taken urgent measures to eradicate the yellow flowers found and deal with them by incineration, and asked the relevant departments to increase the intensity of investigation, if a trace of a yellow flower is found, it should be reported and eradicated in time to prevent the spread of a yellow flower and cause a serious balance of ecology.
The biggest harm of a yellow flower is that it can most powerfully absorb nutrients in the soil, the plant can grow to 3 meters, and spread rapidly, where it goes, it seriously squeezes the space for other plants to grow, so that other plants can not grow, and also shows a spread trend, such as in a region of Chengdu, Sichuan province found about 5 acres of Canadian yellow flowers, has been treated, in Hubei Wuhuang Expressway, Henan Kaifeng Expressway have found a trace of a yellow flower, have been eradicated.
A yellow flower, in the 1920s and 1930s, as an ornamental flower in the alien species, introduced to our country, at that time, no one noticed its reproduction so powerful, can be said to be "yellow flower blooming everywhere a hundred flowers residue", with the invasion of alien species, is considered by the world to be the second largest factor in biodiversity loss, such as the red fire ant found some time ago, the impact on agricultural production is very large, in recent years is still spreading rapidly aircraft grass, have affected the growth of other plants, Therefore, it is urgent to prevent the spread of a yellow flower.
So Canada's alien species a yellow flower, until now people have found that it is very destructive, so it is necessary to take urgent measures to prevent the spread, found a plant to eradicate a plant to prevent spread like an airplane grass, do you think it is necessary to prevent the prevention and control of a branch of yellow flowers?
