What are the hazards and characteristics of plant invasions?

<>1. Invasive plants include: Spartina alterniflora, hollow lotus seed grass, water hyacinth, poison weed, airplane grass, Mikania, Admiralty vine, etc.

2. Spartina alterniflora is a perennial herbaceous plant of the genus Poaceae and Oryza Alterniflora.

3. Hollow lotus grass is a plant of the family Amaranthaceae, and the old locust is listed as the first batch of invasive alien species in China, native to South America.

4. The water hyacinth contains silver reed, also known as water hyacinth and floating lotus, which is a floating aquatic plant of the water hyacinth family of the family Yujiu flowers.

A lot of them, like strangulation of native species, polluting water bodies.

It would endanger the diversity of species in our country. This is caused by alien species destroying the food chain of our organisms and creating competition. Alien plants have just entered the territory, and the native plants do not recognize them, so the alien plants will grow wildly, which will take up space and nutrients, make other plants decline, and indirectly, cause some herbivores to lack food, thus destroying the entire food web.

<>< 5 species of "invader" plants, which are very harmful to the soil!

In nature, not all plants are beneficial to Lu Hong.

Just like bugs, good insects must also be harmful insects.

Plants are also out, and there are many harmful plants.

So how are plants harmful?

It's because some plants grow too aggressively, robbing other native plants of sunlight and nutrients.

Below I will introduce 5 kinds of harmful plants, you must pull them out when you see them.

First, tribulus terrestris.

Tribulus terrestris is a very common weed in the wild, this grass grows creeping and grows extremely fast, and when they grow up, they are already a large patch. This growth momentum is a great threat to other native plants, robbing other plants of nutrients on the one hand, and affecting the area of soil receiving sunlight on the other.

Second, Mikania.

Mikania was originally a foreign plant, but I don't know why it was smuggled into the country, and this plant has a very strong ability to strangle. They can grow quickly, then quickly climb to the stems of other plants, and then strangle other plants, robbing other plants of nutrients and light, and are a harmful plant.

Third, American wormwood.

Ordinary wormwood is beneficial, but this plant native to the Americas is harmful, because they often grow in large numbers around farmland, robbing our crops of nutrients, the key is that the vitality of this plant is very strong, it is difficult to kill completely, so it is better to see it pulled out.

Fourth, silver gum chrysanthemum.

This plant is the natural enemy of many plants and animals, including us humans, because this plant with small white flowers is too harmful. Not only does it grow rapidly, robbing other plants of nutrients, but the key is that it is also a poisonous plant, and its pollen can cause people to suffer from severe allergies.

Fifth, poison weeds.

Poison weed is a very nasty plant, it is harmful, because its appearance is almost the same as that of wheat, but the growth rate is greater than that of small seedlings, so it will rob wheat of nutrients. Secondly, poison weed is a poisonous plant, and many people accidentally pick poison weed when harvesting wheat, which is easy to cause food poisoning.
