Recently, many places in Zhejiang have found a large sea of yellow flowers, although it looks very gorgeous, especially in the background of the sun, but these beautiful flowers will bring great hidden dangers, because they have a name, called Canada a yellow flower. In places such as Bottle Kiln Town, Renhe, Yellow Lake and Liangzhu, there are large areas of a sea of yellow flowers and flowers in Canada, with a cumulative eradication area of up to 291.8 acres.
Relevant personnel also said that although these flowers look very beautiful, foreign pests must be controlled, the most effective way is to directly eradicate, must block these plant killers continue to vine. Every year from September to October is the flowering period of a Canadian yellow flower, if not eradicated at this time, when their fruit is ripe, they will grow more.
When a yellow flower in Canada grows wildly and spreads, it will not only damage the landscape of the garden and green space, but also damage the road and the local ecological balance, including agricultural production will be endangered, especially the dry fields planted with soybeans and corn, which may be invaded by a Canadian yellow flower, and then the crops will not receive enough nutrients, and it is difficult to grow and produce normally. Therefore, the local government also reminds everyone that if you find a clue to a yellow flower in Canada, you must report it to the local agriculture and rural bureau!
Originally, there was no such plant in China, which everyone should see from the name, that is, they are an alien creature. In 1935, a Canadian yellow flower was introduced to China, mainly for ornamental plants, which is probably related to their beautiful appearance and tenacious vitality.
However, when we introduced the species, we found that a Canadian yellow flower directly turned into a vicious weed after adapting to our environment, and it spread rapidly next to the road, around the rural house, in the wasteland and on the river beach, because the super reproductive ability allowed them to spread rapidly where they grew.
People often say "natural selection, survival of the fittest", there is no doubt that a Yellow Flower in Canada has become a "plant killer" because of its vast ecological adaptability, because they will compete with nearby plants for fertilizer, even sunlight, until other plants die due to insufficient nutrients, which directly poses a great threat to the diversity of local organisms.
In the years after the introduction, a Canadian yellow flower can be said to be infamous, because their destructive power is too large, and it can even be described as "yellow flowers are too grass to grow", which is a veritable "ecological killer", and it is not an exaggeration to call it "overlord flower". If you have a Canadian yellow flower there, or even around your house and land, you still have to pay enough attention, don't wait for them to spread everywhere, and then think of a way to eradicate it, then eradication will be more troublesome.
Moreover, a Yellow Flower in Canada is also relatively easy to identify, because it is also a plant of the Platycodon family, so look at each of its small flowers alone, the shape is really a bit like a chrysanthemum, especially the shape of the petals, and some places also call it Unicorn Grass. The color of a branch of yellow flowers in Canada is very bright, that is, bright yellow, and a yellow flower in Canada grows tall, more than two meters high is the norm, so even if you stand farther away, you can see their figures at a glance, and maybe sometimes you have seen them in the arranged bouquet, which is generally used as a matching flower.
Need to distinguish, a Canadian yellow flower and a yellow flower are not the same, because they are two completely different species, moreover, a yellow flower is relatively rare, the rhizome is not developed, can only be regarded as a general weed, unlike the Canadian yellow flower has become the object of eradication. Of course, this is also because the survivability of a Canadian yellow flower is too strong, the wasteland can grow very luxuriant, swampy areas and hillside woodlands can also spread rapidly, you have to find a weakness, that is, they do not like the dark environment, so as long as it is a very tall tree, there will generally be no large piece of Canadian yellow flowers to grow.
Moreover, a Canadian yellow flower will also show differences in leaf color and plant height because of the different environments of the growth place, like the humid environment and often rainy areas, a Canadian yellow flower will not grow two or three meters high without moving, the plant will be thinner, and even the leaf color will be lighter. The reproductive ability of a Canadian yellow flower is so strong, in the final analysis, it is because there are many seeds, because a Canadian yellow flower may have more than 20,000 seeds when the fruit is ripe.
In other words, only one Canadian yellow flower is required to completely pass through the flowering period and the fruit to mature, and a small sea of Canadian yellow flowers can grow around it. Don't ask why it is not a large sea of flowers, because, there is a wind, the wind will bring some of its seeds to a farther place, which is why our country will include a Canadian yellow flower in the list of foreign harmful plants!
