Bai Hana smiled and said, "The farmland is real, but you will know when the forest is not really close!" "
Traveling to sightseeing bus for about two kilometers, Julie stopped at the roadside and looked at the scene before her. Fengmin Agricultural Sandy Land Reconstruction Machinery Team operated all kinds of equipment to transform large mobile sand dunes and semi-mobile sand dunes.
Not far away, the sandy land that has been transformed has become soil gray because of the removal of harmful saline-alkali substances and the doping of a large amount of organic fertilizer, which is quite different from those yellow deserts.
"What is this planted?"
"It should be alfalfa, a plant that can improve soil quality." Baihana telescope looked at the fence sign not far away
Looking at this scene, Julie lamented the industrial strength of human beings, and at the same time, another thought emerged in her heart. "Will the large-scale transformation of the desert cause his ecological problems?"
With such a question, they came to the temporary residence near Fengmin agriculture. On one side of the temporary residence is an artificial lake with an area of 10 thousand square meters, half of which is covered with solar panels, which not only stresses the residence, but also reduces the evaporation of water from the artificial lake.
Zhang Guodong, a researcher of Kubuqi Desert Prevention and Control Project Team of Northwest A&F University, and several leaders of Fengmin Agriculture discussed the transformation of Kubuqi Desert.
Suddenly I saw three girls coming, and there were two white people. Although there were white people in China, Zhang Guodong saw at a glance that the other party was a foreigner after more than ten years of fighting in the northwest.
Although it is not a secret unit, you are very wary of foreigners, and security guards will ask you immediately.
After a meeting, a security guard came to Zhang Guodong to report to the resident team leader that "two foreign women in the yellow group said they wanted to visit our desert control."
Resident team leader just wanted to catch people Zhang Guodong smiled and said, "I’ll show them the yellow group! Anyway, I’m going to inspect the salt sea these days. "
"That’s trouble for researcher Zhang, but be careful." The resident leader woke up.
Zhang Guodong nodded "understand".
Not far away, Julie, Vivian and Hannah stopped to watch and saw a middle-aged man with dark skin and glasses coming towards them.
"Do you want to visit desert management?"
"It is these two foreign friends who want to visit-I am their guide," explained Bai Hana.
After getting to know each other, Julie said the question in her heart, "Is it possible for human beings in dr. zhang to transform the desert on a large scale to cause his ecological problems?"
"Ms. Julie, your question is very deep. If it is a native desert, it is a part of ecology. The transformation of this part of the desert will really cause ecological problems."
Julie asked with some concern, "Will the renovation activities here affect the ecological environment?"
"NO Julie, you have to figure out one thing: what is a native desert and a man-made desert? Hundreds of years ago, this piece of land at our feet was really a lush grassland," Zhang Guodong explained, pointing to the sand at our feet.
"It turned into desert because of excessive reclamation and grazing, and we are now transforming it to restore the ecological environment here."
"So that’s it." Julie suddenly realized.
Traveling to Zhang Guodong, sightseeing bus, took Julie and others to the salt sea in the north, and became more and more dense with the farmland, savanna and "forest" near the salt sea.
At this time, they finally saw clearly that the "black forest" turned out to be pieces of dense solar panels.
"It turned out to be a solar panel and I was still a forest," Vivian said in surprise.
"To some extent, these solar panels are also trees," Zhang Guodong said with a smile.
In fact, he said that there is nothing wrong with the solar power plant in the Kubuqi desert. Although it seems that there is some formalism to design the solar panels in a tree shape.
But solar pool trees have many characteristics of trees.
Trees absorb carbon dioxide and release oxygen through photosynthesis, while maintaining soil and water and maintaining local micro-ecology.
Solar pool trees convert solar energy into energy through light effect and thermal effect, and power plants can extract carbon dioxide from the atmosphere to make carbon powder and oxygen.
Similarly, solar pond trees can also keep water and soil, reduce soil water evaporation and make the local climate more humid.
Solar pool tree is an alternative "silicon-based tree"
Zhang Guodong did not explain in depth.
After a while, sightseeing bus came to the desert control experimental area of Northwest A&F University, and a group of people seemed to have left the desert and entered a sparse shrub grassland.
A few tall Populus euphratica took root at the gate of the experimental area as if they were Zhuang Su soldiers.
There are small shrubs thyme, seabuckthorn, sand needle spear, many onions and a large number of perennial grasses such as sand rice
"How big is this desert in dr. zhang?"
Upon hearing Julie’s question, Zhang Guodong replied without thinking, "About 1.39 million square kilometers have been treated at present, and the remaining two-thirds of the desert area will be transformed into farmland, grassland and solar power plants in the future."
Julie exclaimed, "It is bigger than my hometown of Corsica."
A group of people went deep into the experimental area and saw many students of Northwest A&F University doing experiments or sampling.
According to the overall renovation plan of Kubuqi Desert, 3% farmland, 3% pasture and 4% savanna nature reserve are all in one place for convenient management.
