What does it mean for women to use maple leaves as their heads?
Maple leaf is a maple leaf, which is generally palmately divided, about 13cm long, slightly wider than the palm of an adult. Lobes have several prominent teeth, the base is heart-shaped, the leaves are rough, the upper part is medium green to dark green, the lower veins are hairy, and they turn yellow to orange or red in autumn. But a few areas are dark green.
Autumn is one of the four seasons. In China, traditionally, "beginning of autumn" in the 24 solar terms is taken as the starting point of autumn. Entering autumn means that rainfall and humidity tend to decrease or decrease, and everything in nature begins to mature from lush.
According to the average climate temperature of modern scholar Zhang Baokun, there are four seasons in a year. The index is that the average temperature is lower than 10℃ in winter, higher than 22℃ in summer, and 10~22℃ in spring and autumn respectively.
The reason for turning red:
The degree to which maple leaves turn red is related to time, drought, pollution, especially nitrogen deficiency. The red maple leaves are actually the result of maple trees responding to natural pressure.
The red reaction actually acts as a sunscreen, allowing the maple leaves to stay on the tree for a longer time, thus allowing the tree to absorb more nutrients. It was found that under the pressure of nutrition, especially under the condition of nitrogen deficiency, maple leaves turned red earlier and more thoroughly.
