First, plants grow with sound.
I wonder if flower lovers have ever felt this way. During the growing season of wheat, it is generally quiet at night. When you pass the wheat field, you can hear the sound of "clicking". In fact, this is the movement of plant growth. No matter what plants grow, bloom and wither, they actually have sounds, but the sounds are too low to be heard at ordinary times.
Second, peonies are not actually planted in spring.
Peony, as an indispensable plant in spring, usually blooms very vigorously in April every year, so it is called the king of flowers. However, the peony that bloomed so brilliantly in spring was not planted in spring, but in the autumn of the previous year.
Third, you can't eat mango if you are allergic to paint.
Some people around us who are allergic to paint can't eat mango, because mango is the fruit of a plant of Rhus chinensis, and some ingredients contained in it are actually similar to paint, so people who are allergic to paint can't eat mango, which can easily lead to red spots and redness on the skin.
Fourth, tree rings have many secrets.
As we all know, plants have annual rings. Every year a plant grows, it will add an annual ring. In addition, tree rings can include astronomy, medicine, climate, environment and other issues. When you are in the wild, you can judge the direction according to the annual rings. The wide side of the rings is the sunny south. In ancient times, many ships were made of wood. The age of the victims can be judged according to the tree rings, and the climate can also be seen through the width of the tree rings.
