What plants can be used to forecast the weather?

"People don't know spring birds know spring, and birds don't know spring grass knows spring." It has been found that not only many animals have the ability to observe the earth, but also some plants have this "magical ability". In the plant kingdom, some members can forecast the weather like meteorological stations. Let's take a look at some representative factories with Boqi Bian Xiao.

Feng yuhua

There is a wonderful flower growing in Xishuangbanna, China. When the storm comes, a large number of flowers will bloom. According to this feature, people can know the weather changes in advance, so it is called "Rain Flower". Wind Rain Flower, also known as Red Rain Curtain, Acorus calamus and Leek, is a herbaceous flower of Amaryllidaceae (details) and Eupatorium (details). Its leaves are flat and linear, much like the long leaves of leeks, hanging in an arc. Bulbs are round and slightly thicker than onions. Flowers bloom in spring and summer, and the flowers are pink or rose red. China is native to Mexico and Cuba. It likes to grow in fertile, well-drained and slightly sticky soil and is not cold-resistant.

So, why can Yuhua forecast the wind and rain? It turns out that before the storm, the external atmospheric pressure decreased, the weather was sultry, and the transpiration of plants increased, which made the bulbs of yuhua trees store nutrients produce a large number of hormones to promote flowering, prompting them to bloom a large number of flowers.

Mimosa pudica

Flowers know sunny and rainy days, and vegetation reports the weather. Mimosa is wonderful: if you touch it, its leaves meet and hang down like shyness. Among them, due to the different degree of shyness, the weather is different: if the touched mimosa leaves close and droop quickly, it will take a long time to recover, which means clear skies in Wan Li and Wan Li; On the contrary, the leaves shrink slowly after being touched, droop slowly, or open slightly after being closed, which indicates that the wind and rain are coming.

More interestingly, trees can also predict the weather. Willow in summer, willow leaves droop and sway with the wind, which is a kind of scenery; But if the willow leaves turn white, it indicates that rainy weather is coming. In fact, if you look closely, you will find that it is not that the willow leaves turn white, but that they will all turn over before the rainy day. The reverse side of the willow leaves is light green and there is a layer of "white frost" on the surface. Interested parties may wish to observe and verify it before and after the summer and autumn rainy season.

In fact, not only the plants above can forecast the weather, but many plants in nature have this function, so you can explore and discover it yourself. Moreover, we can also use these plants to predict the weather. Although the accuracy of 100% cannot be guaranteed, it is also an important reference.
