scenery. Bamboo plants belong to the grass family, there are 700 genera and nearly 10,000 species,
in the monocotyledonous plants for the second largest family after orchids. But it is more than the orchid
family distribution is much wider, almost can be said that the earth where there are seed plants
Places, more than the existence of bamboo. But from today's point of view, bamboo is still more concentrated
growth in the tropics, temperate zone, followed. There are more than 200 genera and 1500 species of bamboo plants in China.
I. What are bamboo shoots?
Spring is here, the bamboo garden will emerge from a bamboo shoots, a small tower, the top pointed, and grow quickly, not too much time, will grow into a fresh bamboo. When the bamboo shoots are young and tender, they can be used as vegetables. Bamboo shoots outside the bamboo shell, because the form is different from the general plant, so some people have a bamboo shoots in the end is what the bamboo things doubt. It can be said that the bamboo shoots from the bamboo underground stem (also called bamboo whip) buds grow out of the soil and become a new seedling, the former is actually a young bamboo, which then grows upward to grow, you can form the adult bamboo.
Two, why do you say there are two kinds of bamboo leaves?
There are two kinds of bamboo leaves. Usually when people look at the bamboo, they can see the lovely green leaves on some of the branches of the bamboo poles, which are the common leaves of the bamboo, called "nutritive leaves". Because the bamboo to rely on it for photosynthesis to create nutrients, and stored in the bamboo underground stem, another part of the nutrients for the bamboo itself.
Another kind of leaf is different from the above nutritive leaf, it is called stem leaf, born in the pole and large branches of the various nodes. Growing in the bamboo pole leaf called "culm sheaths" (read tuo), growing in the bamboo big technique leaf called "branch culm sheaths". We see in the bamboo shoots wrapped in thick bamboo shoot shells, the actual culm sheaths. Peel off a bamboo shoot shell to see, the upper part of the bamboo shoot shell has a narrower piece, called culm sheaths, culm sheaths is a special name for the blade. Thick and large part of the area, called "culm sheath" (leaf sheaths special labeling). The original grass in the herbaceous plant leaves are composed of blade and leaf sheath tip two parts, bamboo leaves are also so.
Now add to this the nutritive leaves of bamboo, which are oblong or oblong-lanceolate. If you go to the bamboo forest to pick up a piece of bamboo's fallen leaves, you will find that there is a thin and short stalk at the base of the leaf blade, which is called the petiole. This is in the graminaceous plants only bamboo leaves have this short petiole, bamboo leaves
