is currently the time for Canadian yellow flower to bloom. The golden and bright flowers are blooming in clusters, which is very pleasing to the eye. However, this alien species that competes for sunshine and fertilizer with surrounding plants and poses a serious threat to biodiversity appeared near the snail noodle town in Liunan District, and was discovered by staff from the Agriculture and Rural Affairs Bureau of Liunan District and eliminated in time to prevent future troubles.
In mid-October, when staff from the Liunan District Agriculture and Rural Affairs Bureau conducted a census on invasive alien plants, they found a very beautifully blooming yellow flower growing in large areas in an open space near the snail noodle town in Liunan District. It was suspected that the invasive alien species "Canada Yellow Flower".
According to the report, a Canadian yellow flower is native to North America. In 1935, it was introduced into Shanghai, Nanjing and other places in my country as an ornamental plant. Later, it became wild. Because the plant has the characteristics of inhibiting the growth of other plants in the invading place, destroying biodiversity and changing the structure and function of the ecosystem, invading farmlands to reduce crop yields, endangering urban greening, and producing a large amount of pollen to cause pollen allergies in humans and animals. It can be said that yellow flowers are gone and no grass grows, so it is called an "ecological killer" and has now become a major ecological environment problem.
In view of the destructive nature of Canadian yellow flower to the ecological environment, Liuzhou Municipal Agriculture and Rural Affairs Bureau and Liunan District Agriculture and Rural Affairs Bureau immediately organized experts to go to the site for investigation. It was identified by botanical experts that it was confirmed that it was an invasive alien species in Canada. It also guided the masses to eradicate Canadian yellow flower on site.
In this regard, the staff of the Plant Protection Department of Liuzhou Agricultural Technology Promotion Center reminded that because a yellow flower in Canada has the characteristics of strong reproduction and fast spreading speed, it needs to be eliminated by chemical and physical control methods. Wait for a few days to confirm that all the underground parts have died, and finally the roots are excavated and destroyed in a concentrated manner. Land that has grown a yellow flower in Canada also needs to be monitored for two to three years to prevent the resurgence of the ashes and continued to grow.
Next step, Liuzhou Municipal Agriculture and Rural Affairs Bureau will continue to carry out a census of agricultural invasive species in the city, resolutely curb the spread and spread of harmful plants, and build a solid defense line for the city's biosecurity , thereby protecting the local ecological and agricultural production environment.
