It was very windy outside, and Wang Zhaowen put on his fur coat, put on gloves, and went out with a helmet.

"Where are you going with such a strong wind?"

His wife chased him out of the house and asked.

"Go to the farm and have a look, I may have to go out in the afternoon, and I'll call you then!"

Put on the helmet, step on the motorcycle, and with the roar of the engine, the others are already far away.

"You didn't have your leggings with you!"

His wife's voice chased after him, but the wind was so strong that her voice was drowned out before it was heard for long.

Every winter, the wind and sand in the Hetao area will rise, and this is a very severe test for those who prevent and control desertification.

The destructive power of wind and sand is mainly concentrated on mobility, the power of the wind can make the sand move, and as long as this thing moves, the destructive power will be quite amazing, and the power of flowing sand is unimaginable.

came to the farm and checked everywhere, Wang Zhaowen breathed a sigh of relief in his heart.

Although the wind and sand were very strong, everyone obviously did not relax their vigilance, Luo Xiaolin stayed at the observation station, and the other workers went out to patrol with walkie-talkies at this time.

Because it is close to winter, so the farm has stopped planting new crops a long time ago, but even if it is a plant planted before, at this time under the influence of such a strong wind, it is still easy to be uprooted, the soil viscosity in the desert area is not as good as the inland area, the soil here is relatively soft, if the wind is big, it is easy to uproot the plant, and the wind across the Yinshan Mountain Range, in the process of descending has been accelerated, blowing across the banks of the Yellow River, the wind is reaching its peak, such cold air will not bring rain, but destroy the vegetation, and will blow away the warm air here, so that the vegetation is destroyed, and the rainfall is also reducedThis is how the desertification of the Hetao region has been formed, of course, it is also related to overgrazing, and since the Han Dynasty, the desertification here has begun to be irreversible.

"With such a strong wind, I wonder if those people arrived smoothly?"

After Wang Zhaowen inspected the situation on the farm, the worry in his heart was slightly reduced, but he was worried about the itinerary of the people who came from the south!

……

At the train station, a group of curious young people followed behind a middle-aged man with glasses, looking curiously.

"Wow, is this Wuhai?"

"How's it going, isn't it surprised, isn't it different from what you imagined?"

"yes, it feels like the desert here isn't the same as what you see on TV?"

The elegant professor wearing glasses gently pushed his glasses, and said to his students with a smile: "Hehe, what you see is only the edge of the desert, and the center of the desert is definitely not like this, speaking of which, if the desert is too close to the city, it is also a huge threat to the people living in the city!"

After he finished speaking, he also looked at this desert curiously, and after the train went all the way north, after passing through the Qinling Mountains, the scene they saw began to turn yellow.

It was winter, and the green plants were all withered, and this side was not the south, so it was normal not to see the green scene, but the withered yellow they saw was not the ordinary kind of withered yellow after the plants withered, but an empty, lonely withered yellow, and they entered the desert area.

Although the railway is very close to the Yellow River, there is not much green vegetation on both sides of the Yellow River, which is a difficult thing to understand, because in the eyes of ordinary people, as long as there is sufficient water, plants should be able to survive!

And when people think of the desert, isn't the first thing that comes to mind is the lack of water?

The lack of water in the desert is common sense, and stereotypes have been formed!

Even the vast majority of people think that there is no way to grow plants in desert areas because of the lack of water in desert areas.

This is usually true, however, there are exceptions.

In some deserts, there is only a lack of water on the surface, but in fact the groundwater is quite abundant.

The desert groundwater level in this area of Wuhai is not too high, in some areas of western Xinjiang, the groundwater level below the desert may only be a few meters, which is even much higher than that in the inland areas, and it takes at least six or seven meters to have water to drill a well in the inland area, and to maintain sufficient water sources, the depth of the well is deeper!

But those areas in western Xinjiang, although the water level is high, still have no grass!

Lack of water is only one factor, the environment, climate and many other conditions together determine the survival of plants, but also determine the survival of human beings.

"I've heard they'll put grass squares on both sides, is that all?"

A sharp-eyed student saw something dense in the distance, pointed to it and asked his teacher.

"Well, it should be, these are ancient wisdoms that have been passed down for many years, but what we bring today is something different from these ancestors!"

The elegant professor said with confidence that he was very confident in his research results, although no one believed in his theory yet, and even many people ridiculed him for being whimsical!

Think about it, the problem of desertification is a problem all over the world, even the world's most powerful empire, the United States, is worried about this matter, the United States also has deserts, and they have no way to solve such a problem, and those oil-rich countries in the Middle East, because of the influence of the desert, so that they even need to import food, a strategic material!

Such a thing as oil-for-food can be said to be a fatal blow that directly destroyed Saddam Hussein after the Gulf War!

Tens of millions of people are waiting to be fed, and if they don't take out the precious oil, they won't be able to exchange it for enough food, and if they take out the oil, there will be no military spending!

So, after being beaten down by the Americans, the Iraqis did not stand up for more than ten years, and finally after 12 years, they were completely beaten down and completely broke their legs.

It stands to reason that Iraq, which guards the origins of the civilizations of the Euphrates and Tigris, should not have a food crisis?

In ancient times, they were a big agricultural country, one of the four ancient civilizations in the world, and they were almost the earliest in time!

And Iraq's territory is basically plain, which is much better than Iran next door!

It stands to reason that they should have abundant arable land and high food production!

But because of the desertification of the land, the whole of the Middle East has become a desert, the farmland has become a desert, and the output has naturally been lost, and the life used to be good because the oil was sold well, but now the life is not good, because the oil is not sold well, and the oil can not be burned or burned less, but the rice can not be eaten, and the Middle East countries generally have a serious food crisis, just because of the desertification of the land.

The local tyrants of the Middle East are not stupid, it is impossible for them not to be aware of such a threat, they are not without money, they are helpless to watch their arable land desertification, and they have the money to realize the seriousness of these problems, but they just have nothing to do! Because this is a worldwide problem!
