“Finally, we modified the cells of this drought-tolerant bamboo variety so that it can adapt to this desert arid environment while also being able to withstand floods and water erosion, so there won’t be any problems.

In addition, the bamboo itself is in a closed state, so it can prevent the entry of mold and naturally there will be no corruption.

The water stored in these bamboo joints can actually be used directly and is very clean. "

Hearing what Yang Fang said, Wu Hao couldn't help but smile and said: "Then this is very similar to the traveler's banana we learned in the textbooks when we were children. If it could grow on a large scale in such a desert and arid area, it would be great. It can help those lost travelers solve their urgent needs, thereby saving many lives."

"It's like this. This kind of drought-resistant bamboo can grow to a height of twenty to thirty meters and is as thick as ten centimeters. Under ideal conditions, an adult bamboo can store more than ten liters of water. This water storage capacity can be said to be very considerable. . Just such a bamboo can meet the emergency drinking water needs of more than a dozen people."

Yang Fang nodded and smiled and continued: "In fact, the annual precipitation in the entire northwest region is not very low. The annual precipitation in the Loess Plateau is between 300 and 500 mm, the C Damu Basin is less than 200 mm, and the Hexi Corridor is less than 100 mm, D Huang is only 29.5 mm, T Lupan is less than 20 mm, and R Qiang is 10.9 mm.

Let's put aside the area west of the Hexi Corridor and talk about the large desert Gobi area east of Dhuang. In fact, its annual precipitation is still very good. The reason why it is dry is that its annual evaporation is too large.

This drought-resistant bamboo variety can store water, which means that once this bamboo forest reaches a large scale, it will be equivalent to a reservoir, capable of storing a large amount of water. This will undoubtedly have a huge impact on the improvement of the local environment, especially the microclimate of small areas.

The water it stores can not only support its own life, but it can also support the survival of other animals and plants. For example, there are more than a dozen species of animals living in this bamboo forest.

In addition, the transpiration produced by it can significantly reduce the temperature of the area. For example, through our long-term monitoring, we found that the average temperature here is five to ten degrees lower than the Gobi desert outside.

Even the temperature within a ten-kilometer radius around the bamboo forest will change due to the 20,000 acres of bamboo forest. The average temperature within a ten-kilometer radius around the bamboo forest is two to five degrees lower on average than the desert next door ten kilometers away.

In addition, this bamboo forest can also affect the air humidity in the area and surrounding areas. There is a significant difference in air humidity between here and the surrounding area and the desert Gobi area ten kilometers away.

It should be said that as long as this new drought-resistant bamboo variety passes the ecological safety review and is promoted and planted on a large scale, there will be no problem in restoring ecological vegetation in the desert and Gobi areas east of Dhuang. We are very confident in this. "

"What about the west of D Huang?" Wu Hao asked.

That's not what it wants. There is a large amount of desertified land in Dhuang Yixi waiting to be treated. The natural conditions there are even worse and require more management.

"Of course we haven't forgotten it, but relatively speaking, the management there is more difficult and the cost is higher." Yang Fang said with a smile.

"In fact, this drought-tolerant bamboo variety is also adapted to the growth there, but it is not as good as the one here. And we are also continuing to develop and cultivate more drought-tolerant bamboo varieties that can adapt to extreme environments. The ability is stronger.

In addition, other drought-tolerant plants are also very good. For example, the fast-growing Populus euphratica we focus on cultivating is very suitable for growing in that environment.

We have also developed a kind of drought-tolerant grass seed, which is cheaper to plant and only needs to be spread into the sand. As long as it rains, these grass seeds will grow. "

"Oh?" After hearing Yang Fang's words, Wu Hao and Zhang Jun stopped and looked at each other.

Seeing this, Yang Fang smiled and replied: "This is also a drought-tolerant plant we have cultivated. It is actually a carpet grass that is mixed with the genes of many drought-tolerant plants and then cultivated.

The seeds of this grass are very drought tolerant and can remain dormant for decades in arid environments. Once it encounters water, it will germinate and then develop a very developed root system, which will penetrate into the soil and absorb nutrients.

This kind of grass does not grow high, only about a few centimeters long, and its leaves are relatively pointed, like small thorns. This is also to reduce evaporation, thereby retaining water in the root system, so as to adapt to the extreme drought environment and survive.

This grass has a very strong reproductive capacity. One grass can reproduce and cover almost half a square meter of land in one year, and can reach one square meter in two years.

Because of its well-developed root system, it will firmly grasp the sand and soil, thereby preventing wind and fixing the sand. UU Reading www. uukanshu.com This is much easier to use than the traditional sand-fixing plants and wheat straw grids.

And it also has a characteristic, that is, the metabolism of this grass itself is very powerful, and its leaves basically turn over every year, which is no different from traditional deciduous plants. The key point is its root system. New roots appear every year, and a large number of old roots die every year.

In this way, repeated over and over again, the organic matter content in these desert Gobi sand soils can be greatly improved, thereby increasing the fertility of the soil.

Finally, this kind of grass has another advantage, which can also be regarded as a disadvantage, that is, its reproductive ability is very strong. It can spread by flowering and pollinating seeds in moist environments. In arid environments, reproduction and dissemination mainly rely on the root system.

So once planted, it grows and reproduces very quickly. This is good, but we are worried that once it floods, it will cause an ecological disaster, so we are very cautious about this.

And even if the grass is pulled out, as long as the root system is inside, it may grow new grass after a while. Even if the pulled grass is crushed and thrown into the ground, there is still a chance that new shoots will sprout from the crushed grass roots and new grass will grow.

Therefore, we are more worried that once this kind of grass is not properly controlled and managed, it may spread wildly in the outdoor environment and cause disasters. At that time, it will be very difficult to deal with.

Therefore, this grass is currently being tested in a closed environment in our laboratory, and we are further evaluating its impact on the ecological environment.

In addition, we are also trying to find ways to suppress its reproduction speed, such as preventing it from flowering and producing seeds. Compared with its roots, its seeds have a stronger spreading ability and are more harmful. "
