Ragweed, also known as American mugwort, is native to North America and was discovered in Hangzhou, China in 1935. It is an invasive alien species. Moreover, ragweed has a very strong regeneration ability. The stems, nodes, branches, and roots will all grow adventitious roots. It can still quickly regenerate new branches after being removed and cut. Nowadays, ragweed has been distributed in most areas such as Liaoning, Jilin, Heilongjiang, and Hebei, and it is spreading very quickly.
As a vicious weed, ragweed is also very harmful. Because ragweed has extremely strong vitality, it will cause serious damage to the original ecosystem after entering the native space, squeezing the living space of other native herbaceous plants and plants, and releasing various substances that have obvious effects on native plants. It will also cause a reduction in agricultural production, consume water and nutrients in the land, reduce soil fertility, cause serious losses to agriculture, and pose a greater threat to the ecological environment. In addition, the pollen emitted by ragweed may cause allergic reactions when humans come into contact with it, leading to hay fever, which is harmful to health. And for people with pollen allergies, they may suffer from asthma, coughing, heart disease and other serious conditions.
Ragweed has been designated as an international nuisance weed. Relevant experts warn: China has a large population and a large number of people with pollen allergies. If ragweed cannot be eradicated in time, it will cause harm to people's lives and health. A big threat. According to current data, ragweed has now spread in 19 provinces and cities in China, encroaching on China's land, destroying China's plants, and causing huge damage and harm to China's agriculture. Therefore, the relevant departments of Shenyang City have specially issued an initiative to clear away hot ragweed. Ragweed likes moisture and is afraid of drought, so it must be uprooted to prevent it from growing again. When you see ragweed on the roadside, you should pull it out immediately to avoid further trouble.
