You must be a student.

Learning is on your own.

After all, what others write is someone else's stuff.

You won't need it at any time.

The teacher asks you to write to exercise your ability, not to ask questions for no reason.

I give you reference to what you write yourself for your own development.

I prefer Wenzhu, you just look at Wenzhu.

The expository text describing the plant is as follows:

Bamboo, scientific name bambusoideae (bambusaceae), is a perennial lignified plant of the Poaceae family. The bamboo branches are upright, slender, slim and elegant, graceful and colorful, verdant in all seasons, frost and rain, much loved by the people of our country, one of the four gentlemen of "Meilan Bamboo Chrysanthemum", one of the three friends of "Meisong Bamboo" and so on. Jiangsu Dafeng is the origin of bamboo, and it can be found by searching for Dafeng Forestry Base.

Bamboo is a perennial lignified plant with above-ground stems (bamboo poles) and underground stems (bamboo whips). The bamboo pole is often cylindrical, rarely quadrangular, and is made up of internodes and joints, which are often hollow and a few solid, and the nodes are composed of seed rings and rod rings. Branching on each node.

There are two kinds of leaves, one is stem leaves, commonly known as seed leaves; The other is vegetative leaves, lanceolate, and the size varies depending on the variety. Bamboo flowers are made up of scales, stamens, and pistils. Most of the fruits are fruits.

Most of the life of bamboo is spent in the vegetative growth stage, and once it blooms and bears fruit, all the plants will die and complete a life cycle.

According to the growth of underground stems, bamboo plants can be divided into three ecological types, namely, uniaxial scattered type, zygonal cluster type, and complex axial mixed type. There are many types of bamboo, and there are more than 500 species in Japan, most of which can be used for garden viewing. Common cultivated ornamental bamboos are:

Scattered purple bamboo, moso bamboo, rigid bamboo, cinnamon bamboo, square bamboo, etc., clumping type of Buddha belly bamboo, filial piety bamboo, etc., mixed type of bamboo bamboo, tea pole bamboo, etc.

Most bamboos prefer warm and humid climates, with an average annual temperature of 12C and 22C, and annual precipitation of 1000 mm to 2000 mm. Bamboo's water requirements are higher than those of air temperature and soil, and it is necessary to have sufficient water and good drainage. The adaptability of scattered bamboos is stronger than that of clumped bamboos.

Because the scattered bamboo basically emerges in spring, and the new bamboo has been fully lignified before winter, it has a strong adaptability to adverse climatic conditions such as drought and cold, and the requirements for soil are lower than those of clumping bamboo and mixed bamboo. The underground stems of clumped and mixed bamboos are shallow in the soil, and the bamboo shoot period is in summer and autumn, and the new bamboo can not be fully lignified in that year, and can not withstand cold and drought, so the growth of the north is generally restricted, and their requirements for the soil are also higher than those of scattered bamboo.

I love bamboo.

Grape. There is a vine in front of my house that grows on the wall of the backyard and loves to climb. Its trunk is brown Qingming, which is the kind of dark brown that at first glance, it is reminiscent of an old grandfather.

Its foliage is very lush. From a distance, it looks like a green cloud. He has many hands, always touching this and that, and in summer I like to sit under the vines in the shade, sit on the little maza, and listen to the cicadas.

In September, you can also pick some and invite friends to taste them.

Isn't that fun? It's just that the branch is a little thin, and it's not good if it is torn off by a friend who comes and goes, and the whole cloud begins to shake. It's inseparable.

Therefore, the grandmother who lives next door always says that planting grapes in front of the door can hope that her children will come back to reunite.

Grapes are also divided into many kinds, oval-shaped beauty fingers, round giant peaks, sour and sweet, unique flavor, very refreshing to eat in summer. Grapes contain a lot of vitamin C, which can boost the vitamins you need and are a healthy food. If you don't want to eat freshly picked grapes, you can also choose to make raisins or make wine.

When you make good wine, the whole village will smell the fragrance of grapes, and the aroma of grapes is rich and intoxicating. Flavor.

Sweet and sour with a wine aroma, you will be intoxicated after a few sips. Good wine is not only delicious, but also very good for the human body, for people who often stay up late, grapes can soothe physical and mental fatigue, slow down aging, and can also strengthen the heart.

Grapes have many other functions, grapes also have the wonderful effect of beautifying the skin and cleaning the face, so girls should eat more. The vine in front of the door has gone through five springs, autumns, winters and summers, but in summer, it will still flourish.
