How do the leaves of Cyclobalanopsis change?

Qinggang Tree, also known as Cyclobalanopsis glauca, is an evergreen tree with a wide distribution area. It is not only common in rural areas, but also called meteorological tree. Cyclobalanopsis glauca is very effective as a weather forecast because of the change of leaf color and density, which has been fully recognized by people. Before the rainstorm, the chlorophyll in Cyclobalanopsis glauca will turn red because of the change of ambient air density. If this happens, it will definitely rain in a day or two.

Not only does the ordinary Cyclobalanopsis glauca have such magical weather forecasting function, but an ancient Cyclobalanopsis glauca in China is even more magical. If this ancient tree can grow many new buds before the arrival of Grain Rain, there will be a bumper harvest in the local area this year. If the buds in front of Grain Rain are sparse, it will be rainy this year. If it doesn't sprout, it must be a dry year. After years of verification, there are no mistakes. Can't say it's a miracle of nature.

Cyclobalanopsis wood is not only a good material for making furniture and building materials, but also can be used as amorphous charcoal for metallurgical forging. It is also the main raw material of machine-made wooden shuttles in textile industry, and is also widely used to manufacture vehicles and boats with many functions. Cyclobalanopsis glauca has strong adaptability, especially in calcareous soil, with deep and dense roots and strong drought resistance. It is often used to plant trees in mountain forests and can grow well in rock crevices.

Qinggang Tree belongs to FAGACEAE, and the common plants in the same family are Castanea mollissima and Piperaceae. All the fruits of FAGACEAE can be eaten, but the fruits of Qinggang Tree are astringent, far less sweet and delicious than chestnuts, and can be eaten as food after processing. Cyclobalanopsis fruit is rich in starch, which is a good natural food. It is often used as the main raw material of wine, cakes, tofu and vermicelli in rural areas. Taste and nutrition are better than many starchy foods on the market.

Qinggang Tree is a tall tree with lush foliage, which can grow to more than 20 meters high. Now it has been used for landscaping on both sides of the street, which has played a good role in purifying the air and adsorbing dust.
