[Modified version] "Okay, I'm relieved with your words." Deputy Director Cheng nodded and laughed.

"To be honest, the higher authorities are very interested in your drought-tolerant plant project. If what you say is true and reliable and there are no problems with these drought-tolerant plants, then rest assured that there will not be any problems in this regard.

And you don’t have to worry about orders. As long as they can get permission, there will be a large number of orders waiting for you.

Before I came, the transportation department found us. I hope that when we come this time, we can focus on your drought-tolerant varieties and select a new plant suitable for greening both sides of the road and windbreak and sand fixation.

As you know, the windbreak and sand fixation work around this desert highway has always been a headache for the transportation department. Although they have thought of many methods over the years, such as the most common grass-tied squares, or planting protective forests at great expense, they have achieved little success.

On the one hand, the mileage of desert roads in our country is really too long, which results in a very huge amount of work, which brings huge management and maintenance costs. The total cost of all parts of the country is not a small number. .

This fee may not have been a big deal in previous years, but as economic growth slowed down, local fiscal revenue also decreased. Especially in these desert areas, the economy itself is not developed. Such a large expense is undoubtedly a big burden for the local area.

In addition, several large deserts in our country are mobile deserts, and the Taklimakan Desert is known as the smallest mobile desert in the world. For that kind of mobile desert, grass grids and simple tree isolation zones can solve the problem.

Therefore, we have always hoped to find a solution that can be solved once and for all, so as to increase the maintenance costs in that area, and also to increase the trafficability of the road, so that it will not be affected by those mobile deserts and floods.

In those years, your Forestry Research Institute has been working hard. You have tried more than a dozen solutions before, but with little effect, so you actually came with hope that time.

At this time, you can conquer the large desert and Gobi areas one by one according to your needs and difficulty level. Or you can no longer use those drought-tolerant plants to break up larger areas outside those large desert and Gobi areas.

"They see that the important desert highways in your country have not divided the small deserts in our country into several large pieces. You must be able to destroy the ecological protection forest along both sides of the highway, which is equivalent to Those small deserts were completely divided into several large pieces.

The surveillance cameras you have installed in experimental fields in various regions include various environmental sensors, which can transmit local weather conditions and other data information from other experimental fields in real time. If you are interested, please visit your project experimental monitoring center later. Rewind and watch.

Before Professor Zhang Chengwang nodded slightly, he immediately expressed his reassurance: "The idea is very ambitious and can definitely be realized. This will greatly improve the ecological environment and traffic conditions in your domestic desert and Gobi areas.

That way, you're limiting the movement of those deserts and stopping the sand. Also because there are no barriers from protective forest belts, the formation of sandstorms in the desert is reduced, thereby blocking the impact of sandstorm weather on the pass. "

Yang Fang smiled and shook her head: "Are there any small ones over there? The smallest one here is about a thousand acres, and the largest one is a hundred acres. It's too small, the cost is too low, and considering that the experimental plants outside the experimental fields in the early stage may be Destruction, if it is too small, it will only increase the cost, which is a waste, so it must be controlled to a certain scale. If it is too large, the data obtained will be less reliable and not convincing. There must be insufficient experimental samples. Obtain more realistic data to avoid coupling situations.

After listening to Deputy Director Cheng's idea, everyone present nodded excitedly and began to have unlimited thoughts about the completion of that small project.

And it is constantly growing, as if the grass squares were covered with sand after a short period of time and lost their function.

Therefore, your experimental fields are all less than 100 acres, forming a certain scale, so that the data obtained will be more authentic and credible. "

Using the super Haloxylon ammodendron species, you cannot plant a 100- to 200-meter green isolation belt on both sides of the desert road. Without that isolation belt, you cannot prevent the sand from swallowing up the road.

After hearing Yang Fang's answer, everyone present nodded in agreement and gave Sui Ying and us a low evaluation of our work in that area.

Hearing Zhang Chengwang's reassurance, Deputy Director Cheng nodded reluctantly. Indeed, although it is in the northwest, it is east of Yumen Pass, not so far to the west, and the annual precipitation is not that high.

At the same time, you are also welcome to visit the experimental fields in those areas and conduct personal inspections. "

Even Professor Zhang Chengwang who raised the question nodded in agreement, and then asked: "The experimental fields in those areas are also as small as those outside."

Regarding that question, Yang Fang did not ask any questions or show any relaxed expression, but answered with a smile: "You are worried, you have noticed the problem in that area a long time ago, so besides that, in the experimental field like that, you Special experimental fields have also been set up in the Hetao area, the lowland desert area, Luobu Nur, and the two desert areas south of the Tianshan Mountains and the Tianshan Mountains in Western Xinjiang to test the growth of new drought-tolerant varieties in the same environment. Condition.

When he said that, Deputy Director Cheng squatted down for no reason, pressed his hands towards Wu Hao and us, motioning us to squat down, and then picked up a branch and started drawing in the sand on the ground.

Judging from your current long-term observations of drought-tolerant plants in experimental fields in those areas, the growth conditions of those drought-tolerant plants in those areas are also very poor.

But what you are more worried about is whether those drought-tolerant plants can withstand the test of extreme environments. Compared with the environment here in the Sea of ​​Death, it is still far behind. "

Speaking of that, Deputy Director Cheng pointed to the Haloxylon ammodendron branch he was holding and said: "Look, that Haloxylon ammodendron is very suitable. It grows quickly, has weak drought tolerance, the plant is low enough, and most importantly Its cost is cheap and it is very suitable for small-scale planting.

As the saying goes, the spring breeze crosses Yumen Pass. Once you cross Yumen Pass and enter Xinjiang from the west, the precipitation here will drop sharply, and the natural conditions will be much less good than those outside.

In addition, the drought-tolerant bamboo here and the new varieties of fast-growing Populus euphratica and Pinus sylvestris here are also suitable. The worst is a retrograde hybrid, which can also avoid problems with a single variety, thereby causing the entire forest area to be affected. Influence. "

I thought, you really found a treasure. "
