The Unique Function of Mimosa in Life

Mimosa mainly grows in tropical areas. Mimosa not only has medicinal effects, but also plays a role in weather forecast and earthquake prediction in daily life. So do you know how mimosa works? Here are some common functions of mimosa in life.

weather forecast

Mimosa is a magical plant, which can predict the weather changes. If you touch it with your hand, its leaves will close quickly and open slowly, which means the weather will clear up; If you touch the mimosa, its leaves will shrink slowly, droop slowly, and even open again after a little closing, which indicates that the weather will turn from sunny to cloudy or it will rain soon.

The reason why the opening and closing speed of mimosa leaves can predict the weather is mainly because there is a small drum-shaped parenchyma in the neck of mimosa leaves.

The leaf mattress is filled with water. When you touch the mimosa leaves with your hands, the water in the cells at the lower part of the leaf pad immediately flows upward to both sides, causing the lower part of the leaf pad to contract, the upper part to swell, the petiole to droop and the leaves to close. Therefore, the opening and closing of leaves is caused by the expansion and compression of leaf pads. The expansion effect of the leaf pad is closely related to the humidity in the air. When the air humidity is very low, the expansion effect of the leaf pad is obvious, and the opening and closing speed of the leaves is fast. When the air humidity is high, the opening and closing speed of blades is slow. Therefore, the opening and closing speed of mimosa leaves indirectly reflects the humidity in the air, which can be used as a reference for weather forecast.

Earthquake prediction

According to Turkish seismologist Erjiang, a few hours before a strong earthquake, the leaves of mimosa, which are sensitive to external touch, will suddenly shrink and then wither. In earthquake-prone Japan, scientists found that mimosa blooms during the day and closes at night under normal circumstances. If the leaves of mimosa are closed during the day and open at night, it is a precursor to an earthquake. For example:1938 65438+1October1At 7: 00 in the morning, the mimosa began to bloom, but by 10, all the leaves suddenly closed. Sure enough, 13 had a strong effect. During the period of 1976, members of Japan Earthquake Club observed the abnormal closure of mimosa leaves many times, and then an earthquake occurred. This real event!

In addition, mimosa can also predict disastrous weather changes, and it will produce unconventional growth activities for sudden anti-seasonal temperature difference, geomagnetic and geoelectric changes. We can put some potted mimosa indoors and observe the prediction and prevention of natural disasters.
