Camphor tree can green the environment, beautify life, and balsam camphor tree can be well-being of human beings.
Balsam camphor tree can not only prevent insects and moths, but also has a lot of other drugs can not be replaced. Ancient Chinese medical doctors on the medicinal use of camphor tree has long been research and clinical practice. Chinese herbal medicine collector, Li Shizhen of the Ming Dynasty, he recorded 1,892 kinds of medicine in his life, in his collection of more than 10,000 prescriptions, there are records about the medicinal use of camphor. Such as the balsam fir tree decoction soup, can "bath foot gas scabies wind itch"; with the balsam fir wood to do wooden slippers, can remove the foot gas; "hand and foot gout: cold pain such as a tiger bite." "with balsam camphor wood shavings a bucket, a stone of fast-flowing water, fried pole roll bubble, hot foot in the barrel smoked." Li Shizhen's this record for more than 500 years has been extremely diagnostic, widely used.
Perhaps, you like the upright pine tree, perhaps, you like the millennium longevity of the ginkgo tree, but I like the roadside that commonplace balsam camphor trees, because they are bathed in the morning sun accompanied by me to school, bathed in the evening sun to send me home.
Balsam camphor tree is an extremely valuable species, because the camphor tree is hardy, fast-growing, dust absorption, air pollution resistance, so the roadside is almost all camphor trees.
Spring, the east wind blows, balsam camphor tree will emerge new young leaves. At first, it is just a hairy bud, slightly showing a little bit of green. It takes a few days of work, young leaves from the buds all exposed, initially it is just two opposite light green leaves, a small point occupies the top of the tree branches. As the new leaves grow, the old ones begin to fall off. If there is a wind, large leaves will be like snowflakes, drawing arcs in the air and falling to the ground in a leisurely manner. Even after a day, a thick layer of fallen leaves would accumulate under the tree.
My good friend Pure said that her family also has a few large balsam camphor trees, I heard about it, so I went with a few good friends to see it.
The balsam camphor tree at Pure's house is not very tall, but it is very thick. Branches and leaves, dense leaves shiny green, that nearly oval green leaves have dark and light color: vermilion, tender green, dark green,? It is very nice, and then look closely, found that the leaves above as if a layer of wax, shiny, really like amber or emerald carved crafts, the midday sunlight is strong, the shiny leaves shook my eyes can not open.
Picked a leaf, gently rubbed, a strong natural fragrance comes to my nose, so I do not feel refreshed, I gently picked a few camphor leaves to clip it in the book as a bookmark, so not only the book will be filled with a light fragrance, and the book will not be easy to be moth-eaten. Because camphor itself has a kind of insect repellent aroma, and this aroma can be maintained, even if the leaves withered, its aroma remains unchanged, as long as it exists one day, the insects are afraid of it one day.
Peach trees, pear trees and other trees will bloom, camphor tree is not an exception. We here camphor tree flowering period is generally in April, May or so, balsam camphor tree flowers are very small, rows of panicle-like inflorescence. It is not as delicate as peach blossoms, peonies, but it is y attracted to me, a string of yellow-green flowers quietly dotted in the leaves, exuding a faint fragrance, a wind blowing, a pleasant fragrance cold drilled into the nostrils, so that people are refreshed, relaxed and happy. The flowers of the camphor tree not only attracted me y, but also attracted swarms of bees and butterflies, they dance among the flowers, very lively!
To July and August, the string of beautiful flowers will become a string of light green fruit, to the spherical fruit ripe,
will become black and purple, and sometimes even attract some birds scurrying between the trees, scrambling to peck, and occasionally also issued a pleasant chirp, constituting a picture of "birds pecking! The first time I've ever seen a bird pecking at a tree, I've seen a bird pecking at a tree.
Day after day, the balsam camphor trees on the way to school send me out in the morning and welcome me back in the evening, I do not know that I am about to graduate from elementary school, and the colorful childhood time is also in the image of their falling leaves and green branches slowly far away.

Characteristics of pine trees
Pine trees are distinctive trees.
When we take a car or walk in the cold winter, we always see many trees on both sides of the wide road. And they are all covered with a white coat. And the leaves have all fallen off. People who just arrived here will be fascinated by this silver-colored north, however, we have been living in the north for more than ten years, we have long been accustomed to it. We are used to the monotonous white color, which inevitably makes our eyes a little tired. But in the case of our careful search, we can still find stars of green. It embellishes this northern land. And this is the pine tree. It is this kind of tree that is not afraid of the cold.
The pine tree is very common in the north, but it is different.
Its roots are very deep, and not afraid of the wind and fish, and not afraid of the hot summer sun baked, and he is evergreen. So let us in the extremely monotonous winter, can also find green.
In fact, the pine tree's crown is not lush, branches and trunks are also very sparse. If according to the usual aesthetic standards, the pine tree is never beautiful, and certainly not the best of the trees. However, his simplicity, brevity, strength, vitality and lushness are proof that she is a good man among trees. Pine tree is not afraid of the power of the snow pressure, it is not difficult to let us think of people; pine tree material is good, it is not difficult to let us think that he is the backbone of the country; pine tree simple and upright, it is not difficult to let us think of the military. Can also think of those soldiers generation after generation for the motherland struggle, guarding the motherland's borders.
It is strong and unyielding, defying the wind and frost, the spirit of the seasons forever, how can we not think of guarding our country, day and night to do their best to the People's Liberation Army soldiers? And it does not need people to fertilize, no need for people to irrigate, the winds do not blow down it; floods do not drown it, the cold does not freeze it, it only strive to stand up, a touch of immobility. Don't these show their perseverance, their strength? Our peaceful life nowadays, isn't it their credit, their hard work? So we have to thank them, thank them as the pine tree general perseverance not fall quality.
The pine tree, unlike other trees, is the tree that never fails.
