Everyone has more or less come into contact with composition, especially expository writing. Expository writing helps people understand the shape, structure, nature, type, and cause of things by explaining objective things or explaining abstract matters. , functions, relationships, or have a scientific understanding of the concepts, characteristics, origins, evolution, similarities, etc. of things. How should we write this type of composition? The following is the explanatory text of iron tree that I collected and compiled. I hope it can help everyone. Description of Iron Tree 1
Iron Tree is a sturdy, evergreen plant. There is such a strong and lush iron tree planted in front of my grandma's house. It's beautiful and unique, and I particularly like it.
Looking from a distance, the iron tree looks like a big green umbrella opened, and also like a green spring splashing around. Taking a closer look, you can see that in the center of the iron tree is a thick yellow-brown trunk, like a column, less than two feet high, with fish scale-like patterns on it, which is very rough. The trunk has no branches, and large leaves grow directly from the top of the trunk. The leaves are one meter long, about half a meter short, and about ten centimeters wide. The shape of the leaves is very peculiar. On both sides of a long petiole, there are evenly and neatly arranged slender leaves, like a green comb with long teeth on both sides, and like the feathers of the legendary phoenix. , no wonder people also call it "Phoenix Tail Banana". The strange thing is that the front of these small leaves is dark green, but the back is green. The edges of the leaflets are sharp and hard. If you touch it, you will scream in pain. I thought: This may be the reason why people call this thick tree an iron tree.
Iron tree, cute iron tree! May you grow taller and bigger and become a beautiful scenery in front of grandma's house. Explanatory text of iron trees 2
There are six pots of iron trees in front of the teaching building of our school. As soon as you enter the campus gate, the first thing you see is their stretched figures.
The iron tree is evergreen all year round. In spring, the newly grown leaves of the iron tree are slightly curled, just like a girl's newly permed curly hair. Within a few days, the leaves unfolded, as green as grass, and arranged neatly on the petiole in pairs. Those leaves are very thin, like thin steel needles. You can't touch them. It will sting you and hurt. This may be the plant's self-protection!
The leaves of the iron tree germinate once a year, and become plumper and plump the more they are exposed to the sun. When the old petioles fall off, they will leave traces like fish scales. After a few years, a pineapple-shaped stem will form.
I heard from the old people that it takes a hundred years for the iron tree to bloom, but the iron tree in our school bloomed with magical flowers. The yellow petals are wrapped in layers, forming a small yellow pompon, which is fluffy and extremely cute. This beautiful and peculiar iron tree flower was even featured in our local "Suilin News" and became the "star" of our school.
Iron tree is drought tolerant, waterlogging tolerant and fertilizer tolerant. It generally does not get sick. Once it does, uproot it, remove the old leaves, expose it to the sun, and then rebury it in the soil. Next spring, it will sprout new buds and grow new leaves. It can be seen that its vitality is How tenacious!
Tieshu, I like you, your beauty, and your tenacious character even more. You add green and vitality to the campus. Explanatory text of iron tree 3
Iron tree is called the "living fossil" among plants. It just so happens that my dad's company also has an iron tree. There is a small red thorn on the tip of the leaf, which looks like a spear. The front side of the leaf is linearly concave, and the back side is linearly convex, dividing a leaf into two symmetrical halves. The leaves are very strong on the branches. If your hands don't use a lot of strength, you can't even think of tearing off a leaf from the iron tree.
The leaves and branches of the iron tree have the same characteristics, that is, they are thin and long. The first half of the branch has thin, dense, branch-like leaves, and the second half gradually turns bright red and is connected to the trunk. There are small thorns near the trunk, which are the leaves that have not yet grown up.
The trunk of the iron tree is like a round bucket, and its surface is like scales, which is triangular. The tops of the scales are turned outwards. There are several round "little sarcomas" near the soil at the root of the trunk, like cute little dolls. That is the iron tree. As long as it is carefully separated from the mother body, placed in a separate pot and carefully cultivated, it can become a new iron tree.
People say that it is difficult for thousand-year-old iron trees to bloom. In fact, iron trees will bloom naturally when they reach a certain age and the growth environment is suitable. The iron tree in front of me may not have found a "mate" yet, otherwise, it would already have a "crystal of love", I thought. Tie Shu is full of treasures. It is said that its leaves can not only cure tuberculosis and vomiting blood, but also cure gastritis and other diseases. As for the root, it can prevent stomachache and rheumatic pain, and its seeds can also lower blood pressure.
There is another reason why the name of the iron tree comes from. This is because the bark of the iron tree is as hard as iron. The iron tree likes fertilizers containing iron, so it has this interesting name.
