This grass is notorious for growing 0.2 meters a day. Farmers can't take it, but some people get rich.

There is a notorious weed in our country, it is an alien invasive species, after invading into the south of our country, because it has no natural enemies, it propagates rapidly, occupies a large area of land, and does great harm. This kind of weed is Mikania micrantha, which is called "plant killer". Wherever it goes, it can be said to be barren, and there is nothing farmers can do with it, because it is extremely difficult to cut down and kill the roots.

In fact, it is also a malignant weed in foreign countries, and its English name translates as: grass that grows a mile a minute. Although not so exaggerated, but its growth rate is really amazing, there are scientific studies show that Mikania micrantha can grow 0.2m in a day, all the branches will grow very fast, a year all the branches can grow more than 1000 meters long, extremely destructive. Because Mikania micrantha is a climbing vine, it can entangle trees below 8 meters, and its leaves cover the sun so that the trees cannot photosynthesize and die.

What is more powerful is the super vitality of Mikania micrantha. Every stem node of Mikania micrantha can grow roots, and it can grow roots at any time and can reproduce asexually. Mikania micrantha can be completed in only 10 days from flowering to fruit ripening. The seeds are very small and can be spread by wind, water, insects and humans. The germination rate is very high. Therefore, Mikania micrantha can spread rapidly in China, which has brought serious consequences to the ecological environment. In Guangdong and Yunnan, people's orchards and urban forest parks are occupied by Mikania micrantha, resulting in the death of many trees and the reduction of fruit growers' production.

People have tried many ways to deal with Mikania micrantha, such as using the parasitic plant dodder to deal with it, but the growth period of dodder is only in spring and summer, during which Mikania micrantha is indeed nowhere to be seen, but after dodder withered, Mikania micrantha will mainly grow back, underground roots will grow again, and will absorb the nutrients of dodder for its use, so this method is not feasible. Although the effect of pesticide is good, it will pollute the environment and is not environmentally friendly. It can be said that farmers can only pull it out manually, and there is simply no way to take it.

But Mikania micrantha is not harmful without advantages, because its flowers are an excellent source of honey, beekeepers will chase its flowering season, this kind of honey is very delicious and rare, and it is very expensive on the market, and some people have made a fortune as a result. This is quite surprising. It seems that many creatures have the rationality of its existence, depending on how you use it.
