About discovery and cleaning The news of a yellow flower in Canada has increased, It has aroused people's attention again. In view of several issues of concern, The hour news reporters also carried out multiple interviews. Which department should I go to when I find a yellow flower? In fact, the relevant departments are monitoring and controlling the treatment of a yellow flower every year. For example, the agricultural and rural departments are responsible for agricultural ecosystems, fishery waters and other areas; The natural resources department is responsible for offshore waters, islands and other areas; The forestry and grass department is responsible for forests, grasslands, wetland ecosystems, nature reserves and other areas; The housing and urban construction department is responsible for urban parks and green belts; The water conservancy department is responsible for the water conservancy project area. In addition, the ecological environment department is responsible for the supervision and management of the impact of alien invasive species on biodiversity; The customs strengthened its overseas risk early warning, port quarantine supervision and emergency handling. If you find a yellow flower in the outdoor environment, the specific task of cleaning up is actually assigned to the territorial government.
Is autumn the best season for prevention?
With regard to a yellow flower, a street staff member in Yuhang District, Hangzhou, revealed to the reporter, "There are indeed many complaints about a yellow flower recently. At present, we are carrying out prevention and control work in autumn. Our street invites professional prevention and control companies to clean it up every year. There are two ways to deal with it: eradication and medicine. However, a yellow flower has a strong reproductive capacity, and it often comes back the next year, which is difficult to eradicate." “With regard to the complaints about a yellow flower, some citizens found several trees on the roadside, and some drove to see some trees near the elevated road. In fact, the agricultural land in the farmland, orchard and other agricultural places in the charge of the agricultural department were basically managed, and the incidence of a yellow flower was relatively low& rdquo; A staff member of Yuhang District Agricultural and Rural Bureau said:“ For the prevention and control of seedling stage in spring this year, more than 140 mu of land has been cleared up in Yuhang. Generally, autumn is the full flowering period of a yellow flower, which is easier to be found, and the prevention and control area will be larger.”
What should we pay attention to when uprooting a yellow flower?
Lv Yaobin, director of the Institute of Microflora and Plantation of the Zhejiang Academy of Agricultural Sciences, said that a mature single yellow flower can send out tens of thousands of seeds, which is too powerful in reproduction, and its roots will send out chemical substances to inhibit the growth of other weeds, which is particularly biological. Experts call for the whole people to participate in the prevention and control of a yellow flower, which is too large and difficult to eradicate. When citizens see that it is not just complaints, they can take the initiative to eradicate it if conditions permit. As for prevention and control, experts suggest that it is best to pull it out at the seedling stage in spring, which can effectively prevent recurrence in the next year; During autumn cleaning, the root system of a yellow flower should be removed. Because the flower spike may scatter seeds, it should avoid direct contact with the soil. How can we avoid direct contact between the spike of a yellow flower, including the seeds, and the soil? The expert said: At this time of autumn, the root system of a yellow flower has been deeply rooted, and ordinary people can't pull it out. They must use a shovel to remove it by its roots. After shoveling, there should be a place for stacking, such as on the cement pavement, or spread a piece of oilcloth under it. In short, it should be avoided that flowers, roots and seeds can contact the soil. Wait until it is completely dry and then discard it in a centralized way, so that the harmless treatment is basically completed. |
