What is the Christmas tree tree, they are what time from the beginning to play this sacred duty?

Who is the real Christmas tree

A search of all data, a legend and Jesus has a direct relationship seems to be only a palm tree, the virgin pregnant in October, one day to go out for a walk, on a palm tree and stopped to rest. The palm tree gently surrounded the virgin with the branches and leaves and kept the cold wind outside. Jesus is in the "green screen" in the birth of. But because the Bible clearly recorded that Jesus was born in a stable, the legend could only be a rumor.

Despite the truth, there is still some truth in the legend of Christmas tree. First of all, there are many brown trees in the Middle East, but it is rare to meet one or two pine trees. Secondly, the broad leaves of brown leaves are also a shelter for wind and rain. However, the birthplace of the legendary classic and the difference is obvious, should be regarded as the unofficial hearsay.

In fact, the Christmas tree appeared in the Christmas scene only 1500 years after the birth of Jesus (A. D. 16 century). At the very beginning, there is no practical use, which is used to support the festival atmosphere. A monk cut a small tree on the principle of frugality, and hung cakes, red fruits and candles on the top to make the children in the neighborhood spend a merry Christmas. Later, people compete to imitate, the tree's hangers also become bell gear, snowflakes, small gifts and color lights. Since it is an entertainment prop, there are not many kinds of restrictions, according to local conditions, pine trees, Chinese fir trees can be used. The selection of these trees is only because they are green in the winter, and the waxes of needles or leaves and the waxes outside the needles help them escape the cold and drought in winter. Furthermore, the conical crown is good for decorating, and is simply a shelf for Christmas gifts. It doesn't matter if you have to understand that. In fact, pine and fir trees are just made to avoid the snow and wind.

A spruce that is not a Chinese fir

The tree has come back, and the gift is hung up. If the next day, found the leaves will fall, not spoil the enthusiasm. Some fir trees, such as hemlock, have more deciduous speed than human hair loss. On the second day, the author picked up specimens from the field and returned to the residence very late, and then treated the specimens of Tsuga chinensis on the next day. As a result, in the morning of second days, I found that the lush branches had become a litter.

In contrast, the members of the genus fir and spruce are well done and are green and suitable for long term arrangements. Even second years can be used, as long as there is enough storage space to ask.

At present, commercial planting is the main Christmas tree Abies plants (including silver fir and Canada FIR), partly because they can keep the green branches, on the other hand also because these plants smell fresh and pleasant, let everyone enjoy christmas.

The difference of Matsuwa Sugi's appearance

Although called fir, but they are not members of Taxodiaceae family, but the family members of the pinaceae. The first life of a celebrity was to see their needles as short as the pine needles, so the name of the "fir" was set up.

In fact, the difference between pine and cedar is not the length and length of the leaves, but their cones. Although it is called fruit, the pine and the fir have no real fruit, they are all gymnosperms, that is, their seeds are bare. As for what people call the "pineal fruit", it is just a ball of a seed - like scale - a combination of scales and bracts.

Either pine or fir, each seed has two layers of bract scales that are closely attached to the seed scale and outside. However, a relatively large scale of Pinaceae, Taxodiaceae and bracts is relatively large, which has become the distinguishing characteristic of pine and fir plants.

According to the transformation, cypress plants, especially those of Pinus and Cunninghamia lanceolata, are more special. Their seed scales and bracts are healed together and become the most recognizable gymnosperms.
