"Forecasters" of Plant Meteorology —— Moss

Children, do you know what a plant meteorologist is? There are willow, mimosa, chestnut, Guizijiang and so on. In addition, there is another kind of plant that we can often see outdoors. What is this?

There is an agricultural proverb that says "when the river is covered with moss, there will be heavy rain". Have you guessed? It is Moss Ye Shaoweng, a poet who "should pity a dog's teeth and print moss", who wrote Moss in "It's not worth going to the garden"; The philosopher Liu Yuxi, who is "green on moss marks", also talked about moss in "Humble Room Inscription". Politician Wang Anshi wrote in "Mr. Yin's Book on the Wall of the Lake" that "the eaves of Mao are long and clean without moss". Visible moss was a well-known plant star in ancient times.

In modern times, many stones can also find traces of moss in rivers. It is not only an edible wild vegetable, but also a medicinal material for treating trauma and a good helper for forecasting the weather.

Why can moss predict the weather?

I checked the network information: shanghai dawn, the air pressure dropped sharply. At this time, when the water pressure decreases, the moss at the bottom of the river will surface. People judge the arrival of the rainy season from this.

Moss has many functions, but excessive reproduction will destroy the normal substance metabolism in water and affect the growth of other animals and plants. It is an interesting, useful and dangerous plant, so we should make good use of it!
