Chapter 553

After Zhang Meng left, the Uyghur girls began to sort out the ideas in her mind and arrange the "research" plan.

Just a little while after writing, the telephone on the desk rang suddenly. She picked it up and heard the voice of the female doctor: "Arnel, come to my office for a moment. Something's wrong."

Now the relationship between them is so good that you don't have to be too polite. When she heard the doctor's words, the Uygur girl turned off the computer and went to the doctor's office.

"Xiwen, what's the matter..."

When she came to the doctor's office, the Uyghur girl just wanted to talk, when she found that there were other people in the office, her words stopped immediately.

The stranger in the office was a middle-aged man, thin and dark.

Uyghur girls are experts in biology. As soon as they see the man, they know that his skin is dark with purple and black features, which is only found when exposed to strong ultraviolet radiation for a long time.

In this world, the environment with strong ultraviolet rays is only plateau.

This middle-aged man, apparently from Tibet.

After the Uyghur girl sat down, the female doctor introduced: "this is Comrade Qu jicidan from Tibet Environmental Protection Association. This time, I want to buy a batch of saplings from our company."

After a slight pause, she also introduced to the middle-aged Tibetan man named qujizidan: "this is anna'er Guli, President of our research institute. She is an expert in agriculture and forestry."

"Hello!"

"Hello!"

The Uygur girl shook hands with Qu jizidan, and then the female doctor said to Qu jicidan, "Comrade Qu jizidan, if you have any requirements or questions about the saplings you want to buy, you can tell annar that she will give you a simple and easy way and answer your questions."

Thank you

Qu jizidan thought for a moment and said, "well, our association has been helping the local herdsmen to control the sand recently. I heard that the saplings of your company are effective in controlling desertification and have a high survival rate. So I want to buy some saplings from you and go back to see them. But I still have a little doubt, because the altitude of Zhongba county is relatively high, I don't know if your saplings can be planted alive

"Hiding place? "Swollen Ba County?"

The Uyghur girl was in a daze. She didn't know the geographical conditions and did not know where Zhongba was.

Qu jizidan probably understood the Uighur girl's doubts and explained: "our Zhongba county is located near the source of the Yarlung Zangbo River. Because it is the place where the snow water converges, there are many glacial and snowmelt rivers. In summer, the river in the river flows, which makes the river accumulate a lot of quicksand. In winter, when the weather is cold and the river is less, the sand under the riverbed will be exposed. After the north wind blows, the sand is rampant everywhere, making the desertification of the nearby land more and more serious... "

Listening to Qu jizidan's story, Uyghur girls gradually have a little understanding of Zhongba.

Frankly speaking, it is also the problem of river channel change, which makes the river sand in the original river course be carried out by the wind, and the surrounding land is eroded by desertification.

In Qu jizidan's narration, the local government and herdsmen in Zhongba county have been using grass, wood and stone checkers to control desertification, but the effect is not good.

For one thing, Zhongba County lacks grass for making grass squares. These grasses must be transported from Northeast China, and the cost is very high.

Second, it is light grass checkerboard sand fixation, to cure the symptoms rather than the root cause.

Grass checkers have a service life, and they will be scattered in two to three years. It is a waste of manpower and material resources to hit again every two or three years.

Therefore, Zhongba county hopes to find vegetation that can be planted and consolidate soil and water.

"Over the past few years, we have been looking for suitable seedlings, but we can't find them, because the altitude is too high and ordinary trees can't be planted..."

Qu jicidan introduced the situation of Zhongba County carefully. The female doctors and Uygur girls listened quietly.

After listening for a while, the Uygur girl suddenly asked, "is the soil particularly wet in summer? In winter, it will become very dry again

Qu jizidan nodded: "yes, in summer, the glaciers and snows melt, and the ground is full of water. In fact, there is no shortage of water. But when it comes to winter, many rivers will be dry. The sand is rampant, and sometimes the snowstorm is severe. Local people say that the snowstorm will only blow for a few days, but the sand has been blowing and will not stop. "

After a slight pause, the middle-aged man said, "because of the problem of land desertification, Zhongba county has twice relocated the county seat. The situation is very bad, and it has a great impact on the people's lives..."

The Uyghur girl didn't listen to Qu jizidan's rambling words. She suddenly remembered one of the ten techniques Chen Mu had given him before, one of the new varieties of Acacia pseudoacacia.

Before, she was going to put this Acacia in the last place, but now she met Qu jicidan, and she suddenly felt that this was a good opportunity. She should make this new species of Acacia first.

He was a little distracted when he was not careful. When Qu jizidan finished his speech, he saw that the Uyghur girl didn't say anything. The female doctor quickly reminded the Uyghur girl, "annar, Comrade Qu jizidan hopes to find a kind of sapling that can grow in Zhongba county and has the effect of sand control. Do you have any suggestionsAfter thinking about it for a while, the Uygur girl said, "Comrade Qu jicidan, after listening to your words, I have analyzed the situation in Zhongba county. The seedlings you need should first be resistant to cold, because you are on the plateau glacier boundary. If you can't resist the cold plants, you will not be able to survive, right?"

"Yes, it is. It's very cold in winter. Ordinary plants don't live."

The Uygur girl continued: "secondly, there is a great difference between the dry and wet environment in winter and summer, and the self-regulation requirements of plant roots are a little high. Many seedlings that can be planted in the desert should not live in your place."

Qu jizidan quickly nodded: "yes, we have also bought some seedlings with good sand control effect to remove swelling, such as Haloxylon ammodendron seedlings, Salix psammophila, flower sticks But the effect is not good, not live. "

The Uygur girl then said, "the last point is that you are located on a plateau where the air is low in oxygen, and trees can not be planted without oxygen. Therefore, generally speaking, the plateau area is dominated by low-lying Carex vegetation."

Qu jicidan nodded again: "yes, the altitude of Zhongba county is above 4700. Generally speaking, it is difficult to grow tall trees Well, it's said that some spruce and Pinus sylvestris have been planted in Quna in the past two years. I don't know the specific situation. "

After a slight pause, he looked at the Uygur girl with expectant eyes: "Comrade annar, I only briefly introduced the swelling situation. You can see that you are really an expert. I don't know if you have any good suggestions and what saplings can be recommended to us."
