The winding paths lead to secluded areas, and the green bamboo tops block these paths. Only a few spots of light shine directly through the bamboo leaves, making it very refreshing.
Wu Hao walked up to a bamboo, looked at it carefully, and then said: "This bamboo looks no different from our ordinary bamboo."
After hearing what he said, Yang Fang replied with a smile: "This drought-tolerant variety is actually not much different from ordinary moso bamboo poles. It's just that the surface of this bamboo pole is relatively rough and not as smooth as traditional moso bamboo."
After hearing Yang Fang's introduction, Wu Hao touched it with his hand and found that the surface of the entire bamboo pole was relatively smooth, but not as smooth as ordinary bamboo.
With that said, Yang Fang casually broke off a bamboo tip and handed it to Wu Hao and said: "The biggest difference you can see in this drought-resistant bamboo is the bamboo leaves. The width and length of traditional bamboo leaves can basically reach two to three centimeters.
Even three to four centimeters, the length can reach about fifteen to twenty-five centimeters.
As for the bamboo leaves of our drought-tolerant bamboo variety, its width is only one-third or even one-quarter that of ordinary bamboo. The width is less than one centimeter and the length is only ten to twenty centimeters. Relatively speaking,
There are more bamboo leaves.
In addition, this bamboo leaf feels thicker and has a layer of wax on the surface, so it feels smoother. However, traditional bamboo leaves are thinner, have obvious texture, and feel rougher.
All the changes are actually to adapt to the very strong light in the Gobi desert area, thereby reducing the evaporation of plant water by light, making it more suitable for the harsh environment of the Gobi desert.
In addition to being resistant to high temperatures and droughts, this kind of bamboo leaves can also withstand severe cold. Its special texture is more cold-resistant than traditional bamboo leaves, so there will be no problems even in the cold winter."
Having said this, Yang Fang easily cut off a two-three centimeter-thick bamboo with a knife, then cut one short and split it, handed half of it to Wu Hao and said: "The texture of this bamboo is similar to that of traditional bamboo."
There is not much difference, except that its texture is more delicate than traditional bamboo. This is also to adapt to and resist the strong winds in this desert area. In addition, this texture is also beneficial to bamboo.
Transport moisture.”
Speaking of this, Yang Fang pointed to the cavity inside the bamboo pole and said to several people: "You can touch it with your hands. The internal texture of the bamboo joints is relatively soft and the inside is relatively moist. This is also
In order to be able to store more water for the bamboo to meet its needs.
It can absorb moisture from the air and underground through its roots, including bamboo leaves, and then store it inside the bamboo, including some bamboo joints. When drought requires it, the water stored here will be slowly absorbed and digested by the bamboo.
In fact, many plants in nature have such functions, such as a desert plant native to the northwest called desert rhubarb.
Desert rhubarb is very adaptable to its distribution and can grow even in harsh environments. The most special thing about it is that its leaves have special functions and can water their roots independently, which sounds very magical.
The structure of its leaves is quite special and looks relatively large. When it rains, the leaves will automatically slide the rainwater down to the roots, and its roots have the function of storing water. After investigation, it was found that the amount of water it collects is 16 times that of other plants in the same area.
It seems that it is no wonder that they can survive in the desert.
Desert rhubarb can store 4.2 liters of water every year, and some can even store up to 43.8 liters. You must know that the annual rainfall in desert and Gobi areas like the northwest is very small, so being able to store so much water shows how extraordinary it is.
Another example is our most common cactus, which can adapt to growing in the Gobi desert and is a very good drought-tolerant plant. In addition to its very strong vitality, it also has its own water storage function, and its rhizomes can store a large amount of water. In this way
No matter how hot and dry the season is, no matter how harsh and desolate the environment is, it can still adapt to survive.
There is also the bottle tree from South America, which also has a very powerful water storage function. It can store a large amount of water in the rainy season, and the water it stores can supply its own needs in the dry season.
In order to allow this drought-tolerant bamboo to survive in desert and arid areas, we have also made relevant modifications so that its bamboo joints and root bamboo joints have a certain water storage function.
In this way, it can absorb water during rainfall or irrigation, store it in the bamboo joints and root bamboo joints, and slowly absorb it when needed."
At this point, Shen Ning got a freshly dug bamboo root from the staff, cut it off with a knife, and then lifted it up and tipped it downwards. Several drops of water fell out from the bamboo joints of the bamboo root.
This made Wu Hao and Zhang Jun very curious. Zhang Jun personally took the bamboo root and used it until it was soldered. Sure enough, water could be poured out.
If there is water in the bamboo joints, will this cause the bamboo poles and bamboo roots to rot? Zhang Jun immediately questioned it. After all, in his knowledge, whether it is bamboo or trees that have been soaked in water for a long time, they will rot and die. He previously raised
Many of his flowers were watered to death in this way. He always felt that they needed watering, but in the end they were watered to death, so his impression was naturally very permanent.
Yang Fang smiled and shook her head and said: "No, bamboo is not the same as trees. It is a kind of water-loving plant. It is not afraid of being soaked, so we can see a lot of bamboo growing near water.
Secondly, the texture of bamboo itself is relatively tough, not afraid of being eroded by water, and not easy to rot. We can see that many bamboo rafts are made of bamboo. Why? In addition to the fact that it is a cavity with buoyancy, it also has
It's just that it's more resistant to soaking and less likely to rot.
Finally, we can see that many bamboo poles in the south are damaged, and a lot of water has accumulated inside. Even many tree frogs will live in the water-filled bamboo joints for many years.
Such bamboo still has not rotted, which shows that bamboo has a relatively strong ability to resist water penetration and corrosion.
In addition, we can also see the so-called bamboo tube wine and bamboo leaf wine produced in many areas in the south. They actually drill a small hole in the bamboo joint, then pour the wine into it and seal it for a few years, and then take it out.
The sealed wine has the fragrance of bamboo and the flavor is very good.
Of course, these are not enough, so we have worked hard on the membrane inside the bamboo joints to make it waterproof to a certain extent and can resist water erosion and penetration for a long time.
And this bamboo film will also continue to metabolize to resist water infiltration, thereby preventing the bamboo poles from rotting due to exposure to too much water."
