"The shadow of the southeast good wood is swaying, and the branches and leaves are dense and condensed in the morning dew. Like a girl looking forward to leaving, Taiwan has the most lovesick tears. In early summer May, walking on Egret Island, looking up, the acacia trees on the distant mountains form a sea of golden flowers, which can be described as "the city is full of golden armor". Recently, on platforms such as Xiaohongshu and WeChat Moments, acacia trees are "too popular".
■Along the mountain and sea health trail, acacia trees bloom golden. This newspaper shoots and learns endlessly
In Xiamen Garden Botanical Garden, Shangli Reservoir, Huwei Mountain, Xianyue Mountain, Mountain and Sea Health Trail, Dongping Mountain...... The blooming of the acacia tree attracts tourists and photographers from all over the world to hold "long guns and short cannons" to retain this splendid beauty.

It is understood that most of the acacia trees on the mountains of Xiamen Island are the "old people" planted in the late 50s and 70s of the last century. In that year, Xiamen carried out afforestation and greening actions, and the tree species were mainly acacia and masson pine. Because of its rapid growth, drought resistance, barrenness resistance, typhoon resistance, and can be planted by the sea, it became an important tree species for afforestation, soil and water conservation and coastal shelter forests in South China.

Acacia trees bloom every year, why is it attracting so much attention this year? In addition to the fact that more people shared the flowers of the acacia tree on social media, everyone also felt that there were indeed more flowers blooming this year. Folk flower cultivators believe that there was a low temperature tide at the beginning of this year, and after a period of freezing in winter, there will be more flowering this year, and the professional term is called "low temperature vernalization", which refers to the fact that some plants have experienced a period of time in a low temperature environment, and the differentiation and development of flower buds have been promoted, and the quality and quantity of flowering will be improved and increased.

Xiamen people's "lovesickness" >>>
Xiamen people are not only familiar with acacia trees, but also love them very much. In 1986, when the city tree was selected, the acacia tree was second only to the phoenix tree in the voting list. According to the voting data of that year, Phoenix received 5,484 votes, accounting for 51.9% of the total votes; Acacia received more than 3,500 votes, accounting for 33.5%.
For the older generation of Xiamen people, acacia trees are also accompanied by many childhood memories. "Acacia trees will have small caterpillars hanging down, when I was a child, I accidentally encountered them on the way to school, and I would be afraid at first. Mr. Ke, a citizen, said that he still remembers the embarrassment of being red and itchy at the back of his neck by a small insect of the acacia tree at the same table in elementary school. In addition, in the seventies and eighties of the last century, the branches of the acacia tree were often broken off by naughty children to make slingshots.
"The leaves we see are actually petioles." Chen Hengbin, former deputy chief engineer of Xiamen Garden Botanical Garden, said that acacia is an evergreen tree of the genus Acacia in the legume family. The green leaves you see are leaf-like stalks. He said that the acacia tree, which is native to the Philippines, reaches a height of 6 to 15 meters. At the seedling stage, the first true leaf is a pinnate compound leaf, and when it grows up, the leaflet will degenerate, and the petiole will become a petioles, 6 cm to 10 cm long, 5 mm to 13 mm wide, showing a straight or slightly curved sickle-shaped, with two ends gradually narrowing, with three or five obvious longitudinal veins.

Science
The name of the tree is very romantic, the vitality is very tenacious, and it >>>
According to legend, the acacia tree was reincarnated after the martyrdom of Han Ping and his wife He after the martyrdom of the Warring States Song Kang Wang. Therefore, the acacia tree is seen as a symbol of loyal love. "The bottom of the acacia tree says that it is lovesick, and Silang hates Langlang and does not know." Liang Qichao once wrote in "Taiwan Bamboo Branches".
Acacia tree has many names, also known as fragrant silk tree, acacia boy, etc., Guangdong region called Taiwan acacia, Fujian area called acacia tree. In Taiwan, people are more accustomed to being called Acacia Boy.
From May to July every year, the acacia tree blooms. The crown is abundant, the posture is erect, the flowers are golden yellow, there is a slight fragrance, and the leaves are yellow-green. If you look closely, the bunches of small yellow flowers are fluffy and cutely round.
Due to the verdant green canopy, acacia trees become excellent shade trees, street trees, landscape trees, windbreak trees, and slope protection trees, with low maintenance costs. One of the characteristics of acacia trees is that "wildfires are inexhaustible, and spring breezes blow and regenerate", and the growth characteristics are that the seeds have strong germination and fast growth rate. When a wildfire is burned, it can continue to sprout and grow in the second year, and it will break when it is stopped by strong winds, and it is also full of vitality.
In addition to being adaptable, acacia trees also have a strong ability to fix nitrogen, which can make fertilizer for themselves and improve green spaces. A fallen leaf can absorb 3 times its own weight of water, and can absorb about 40 tons of water a year, so after planting a large area of multi-purpose fast-growing acacia trees, it has a good effect on improving the soil, preventing soil erosion, and improving the ecological environment in the forest.
Acacia trees have extremely high economic value and excellent materials, which can be used for shipbuilding, vehicles, farm tools and machinery. The bark contains tannins, and the flowers contain aromatic oils, which can be used as raw materials for flavoring. Wood can also be used as pulp, wood-based panels, furniture, bark can be extracted from tannin gum, economic and ecological benefits are very significant.
