Jiang Yu remembers that Qi Guanglu is already over seventy years old this year, but she looks younger than eight years ago.

Zhao Yun smiled and said, "People feel happy when they are happy. Professor Qi's project team has achieved such great achievements, which makes Professor Qi look much younger."

The results of Qi Guanglu are obvious. When Jiang Yu came last time, although there were new varieties of wheat planted here, the surrounding environment was still relatively desolate.

It is now a green scene, and you can still see the sparse woods in the distance.

Qi Guanglu introduced to Jiang Yu with a smile: "In fact, there is no new breakthrough in the Green Field Plan. We have thought of the way to create green space here, but we have only made enough technological progress in recent years."

He led Jiang Yu and others: "Please come with me."

This green area in the desert is the grass at the outermost point. It takes dozens of meters to walk inside to be the main crops in the north, such as wheat, corn, etc.

As soon as he entered the crop area, Jiang Yu felt that the air humidity here seemed to have changed a little.

Qi Guanglu walked in front and introduced: "In fact, many people shouted about soil erosion every day, but they didn't know the meaning and harm of soil erosion.

"A poplar tree can usually store hundreds of kilograms of water during the rainy season, and a poplar forest can almost absorb the excess rainwater that can cause floods.

"Without flooding, the land resources in the woods will not be lost, and the moisture absorbed by the trees will be gradually released into the surrounding environment to ensure that the surrounding environment has enough moisture.

"But when the woods are gone, the soil and water will no longer be retained, and complications of soil erosion will also occur.

"Trees that do not absorb water will easily cause floods. Without trees that continuously release water resources, they will easily cause drought."

While listening to Qi Guanglu’s knowledge, Jiang Yu saw a tall white tower not far away.

This white tower is made of metal, from the bottom to the top, it seems to have circles of small holes.

Qi Guanglu was taking them to the direction of the White Tower, and he smiled: "Here, you must be unable to feel the dryness in the desert."

He smiled mysteriously: "We used to think that no matter how much effort we spend in the desert, a dry wind blows over and can take away all the water vapor in the air.

“But our achievements changed our previous perceptions, when enough plants were planted in the desert.

"Their respiration can change the climate and environment of the desert to a certain extent.

“Just like the example of soil erosion I just mentioned, when the vegetation that can adjust the water resources of a region comes back, the climate in the entire region will become healthier.”

Lu Qingfeng said curiously: "But this is also the concept of 'Chicken', raw eggs', how can we make enough plants in the desert? Can we produce a respiration effect that changes the climate in the desert?"

Qi Guanglu pointed to the white tower in front: "It is it, we call it a small ecological adjustment system. Although it still needs to be improved, you have also seen it, it has created an oasis."

Jiang Yu looked at Baita and asked curiously: "What does it work?"

Qi Guanglu smiled and answered: "Do you still remember the proposals proposed by our water transport team twelve years ago?"

Jiang Yu nodded: "I remember it roughly."

"The plan to build climate regulators in space was abolished five years ago," said Qi Guanglu: "This plan is too advanced, and there are too many theoretical and technical obstacles.

“So we put all our energy into the planning of the hydration system.

"This is inspiration from artificial starch. Although it is difficult to transport water, it is relatively easy to transport the hydrogen and oxygen that make up the water.

"Thanks to the huge investment of Moon City, we designed special trains for pressure resistance and refrigeration, and built more than ten kilometers of railways to allow liquid oxygen and liquid hydrogen to be transported directly from the seaside.

"This special train can transport thousands of tons of liquid hydrogen and liquid oxygen once."

Jiang Yu and others looked at the small holes in the Baita and roughly understood how this system works.

Qi Guanglu continued to explain: "If it is more than a thousand tons of water, it is a drop in the bucket, but the transportation of liquid hydrogen and liquid oxygen is different.

"In liquid state, they are equivalent to compressed hydrogen and oxygen, with a high density and a large single-time load, while liquid water is difficult to compress.

"We have a hydrogen production plant and oxygen production plant in Qinhuangdao, which directly uses seawater to produce hydrogen and oxygen production, and then transport it here.

"After adding liquid hydrogen and liquid oxygen to a small ecosystem in proportion, the two liquid gases are first vaporized and then synthesized water vapor through reaction.

"Then release the water vapor from these small holes and evenly spread onto the surrounding vegetation."

Jiang Yu nodded, and he was more concerned: "How is the cost?"

Qi Guanglu smiled and said: "The water transportation team has done relevant technical breakthroughs, especially hydrogen production technology, because nuclear tests conducted in space now require a large amount of hydrogen.

"This has greatly improved the efficiency of the hydrogen production industry and also reduced the cost.

"The liquid hydrogen we use does not require further purification, and the oxygen production process has long been very complete.

"The test field uses wind and solar energy to generate electricity, which is enough to convert liquid gas into liquid water.

"Overall, this average-cost crop is difficult to make a profit, so we are now cultivating some cash crops.

"But the significance of this system is indeed extraordinary, completely ending the problem that has been difficult, expensive and prone to repeated desertification control in my country since the last century.

"If there is enough funds, there will be no desert in the country, and even the world will no longer have deserts!

“The land that humans can cultivate has doubled, and there will be no more sandstorms!

"We have mastered the way to transform the earth! This is a huge progress in human civilization!"

Qi Guanglu joked: "We should pay attention to the overall increase in the global oxygen content."

Jiang Yu squatted down and touched the green grass beside the white tower. The green grass grew very thick, making the sandy ground tighter.

Green grass blocks the sand below, and vitality blocks the desolation.

He asked: "How big is the test field now?"

"It's nearly 600 acres." Qi Guanglu replied: "This is a relatively early batch of experimental fields, mostly crops, and there are some woods with developed root systems to the north.

"We found that 500 acres are probably the dividing line for improving local climate. The local climate below is not much improved, and there will be obvious changes above."
