Live broadcast: Ancient people accompany me to make up lessons

["At the Huaishuzhuang Protection Station in Qiaobei Forest District, Yan'an City, the reconnaissance team is completing preparations before departure. The drone reconnaissance team has a crew of two people, and the Qiaobei Forestry Bureau has a total of more than a dozen crews..."

The pickup truck stopped at the designated location. Forest fire prevention personnel wearing camouflage uniforms and red armbands arranged the black and white drones, picked up the remote control equipment, and started operating. ]

Everyone didn't understand what a drone was, but everyone was astonished when they saw the small things on the ground light up with red dots, the blades at the four corners rotating, and suddenly flying up.

People from the Mo family and Gongshu family remembered the appearance of this drone. They were good at drawing and had quick hands (hand speed that everyone was forced to learn since seeing the sky curtain). They copied the shape, and then pointed to the four corners of the paddles to understand this. It’s the key to being able to fly.

So, how did it turn around?

Tao Wanhu, a Tao Chengdao who worked tirelessly to reach heaven in the Ming Dynasty, looked at this rotating blade and his mind fell into thinking. If this drone flies by rotating its blades, then isn't it wrong for it to try to imitate a cannon and shoot itself out?

["This investigation point is within the Ziwuling National Nature Reserve. The reserve is located in the hinterland of the world's largest Loess Plateau, the area with the most severe soil erosion in the Loess Basin..."

Several drones took off and rushed into the blue sky in the distance. Then, a large area of ​​lush green filled the screen. ]

"This is too green..."

The drone footage is full of green, and even a curved rainbow under the dome.

"It's so beautiful..."

Everyone in the dynasty with its capital in Chang'an recognized the "barrier of the Guanzhong Plain". At the same time, they were wondering if most of the trees had been cut down by the time they were here, and some people began to feel guilty.

In a village in Guanzhong, some young people were incredulous: "They use this just to prevent the trees from burning?"

The person next to me said: "Didn't you also say that you should prevent others from cutting down trees and poaching?"

Another person expressed dissatisfaction: "They are not even allowed to cut down trees or hunt, and they are not even allowed to burn firewood. How can that person live!"

Someone else asked: "If too many trees are cut down, and the wind and soil are gone when it rains and blows, how can people survive?"

The elderly man asked directly: "Do you like to see the mountains full of green trees, or do you like to see the loess?"

The dissatisfied young people fell silent. They are people who live in the loess land. When the wind blows, there is yellow sand everywhere. Of course, they still like the green mountains.

This is a discussion about the foresters' work enthusiasm, and some people are discussing the use of technology.

"Modern technological means... They use this magical drone and other infrared cameras just to ensure that this land can stay green. Isn't it too expensive?"

"Listen carefully to the lecture. Only here it is green and the trees are holding up the soil. The floods in the lower reaches of the Yellow River will at least have less sediment blocking the river."

"You can even see leopards at night from up here!"

"It turns out that before these technologies existed, they still had to walk on their feet..."

[The lush woods have changed to a place where different green plants are planted, and the bare yellow earth is still obvious. Several red signboards standing on the ground of "Yulin Million Acres of Scotch Pine Demonstration Base" are introduced to the eyes.

"Yulin, called Shangjun in ancient times..."]

Looking around are yellow sands that produce no grain. Is Shangjun so desolate?

Everyone who was there earlier couldn't believe it, because the Yulin at this time was not at all what it said on the sky screen, with trees and water, and it was very beautiful.

Considering its border location, some people can understand why its environment is getting worse.

Throughout the dynasties until the Ming Dynasty, especially during the Ming Dynasty, border farming destroyed a large amount of vegetation. By the Kangxi period, the people of Yulin sighed in unison as there was no land left for farming.

High mountains, deep ravines, windy sand, and poverty are not what Yulin is like now.

After sighing, he cheered up again and saw if he could start from his own generation and transform Yulin into what future generations would look like.

["One day in 1993, the Food Organization of the United Nations solemnly awarded the Dr. Rao Award to Niu Yuqin, a rural woman in Shaanxi."

A square building with blue glass on the outside appears, with the words Niu Yuqin Desert Control Exhibition Hall on it.

“This year, only three people in the world received this honor.”]

She is not a well-known talented woman, nor does she have any noble status. She is just an ordinary rural woman. The image in the color photo is also plainly dressed, with traces of weather on her face, but her smile is also very simple. Nothing fancy, but with an indescribable vitality.

Everyone's eyes widened, and they didn't expect that the award, which sounded very impressive at first glance, would actually be received by such an ordinary old woman who seemed to be seen in every village.

why?

["Decades ago, Niu Yuqin married into Jinjisha Village, Dongkeng Town, Jingbian County. At that time, there was only one poplar tree in the desert, which gave her the belief to change her living environment. Now, this place built by Niu Yuqin The base is also named 'One Tree'..."

The barren land in the black and white photo has turned into a yellow-green land with intertwined green plants. ]

No one can listen to Niu Yuqin’s desert control story without being touched.

Ten thousand acres of deserted sandy land. I sold my property and borrowed money. The 6600 acres of saplings I planted in the first year were all blown away by the wind and sand. I was not discouraged. In the second year, people were hired to carry donkeys and camels, so I continued to plant. Tree. From acres to acres, an oasis was carved out of this desert.

Over the past thirty years, we have been heavily in debt for tree planting, and we have used the only money we have to repay loans to build primary schools. In order to help villagers fighting desertification get rid of poverty, tens of thousands of tree saplings have been cultivated and provided to everyone free of charge. More on this later. They organized villagers to dig machine-operated wells and transformed more than 3,000 acres of irrigated fields.

Wang Shouren looked at his wife who was also listening with rapt attention and said: "This is not a 'slut', this is a truly amazing woman..." She deserved her honor.

"I would rather be exhausted to death by sand control than bullied to death by sand," after reading this sentence, the eyes of people in areas where the ecological environment has become increasingly severe lit up.

A little kid shouted: "Grandpa, grandpa, we can grow up in a place like this where we can't grow much food, how can we let these sand bully us?"

The increasingly poor people who already live here also feel this way.

[In addition to Niu Yuqin, there are also people from northern Shaanxi who brought more than 5300 million trees and shrubs to life at the yellow sand alkali stall, the first national desert control hero Shi Guangyin, and Zhang Yinglong who gave up development in the capital and chose to return to his hometown... Every Everyone is so ordinary, yet so extraordinary.

Pinus tabulaeformis and Platycladus orientalis seeds that have been specially treated to facilitate germination, Pinus sylvestris native to the Hulunbuir Sands, and magical caragana.

Caragana roots of leguminous plants have many spherical structures, which can turn nitrogen in the air into nutrients that plants can absorb, and synthesize ammonium salts. The longer they are planted, the more fertile the land around them will be, and they can also make other more Plants grow all around.

In addition, there are poplar trees, Polygonum spp., Liedang trees, and Dishao melon trees. ]

The eyes of people in areas with barren land lit up: "This Caragana can actually fertilize the land!"

"I've seen this one, and that Polygonum spp., they're all from the desert area further north!" The traveling caravan had a good memory and remembered these plants on the grassland.

[In order to reduce the flow of sediment into the Yellow River, some people plant trees on the cliffs with steep mountains and weak soil layers.

Smart locals used stones to build fish scale pits, transported the soil from the mountain here bit by bit, and then planted trees.

"This method of 'rock pits and soil' makes the mountains that are originally rocky cliffs covered with green. The connected stone pits are also called fish scale pits because they resemble fish scales.

In addition to the fish scale pit, there are also check dams and dry farming terraces. Different management projects are connected together to comprehensively control soil erosion in small watersheds. ]

The continuous fish scale pits, the distinct layers of terraces, and the check dams accumulated over thousands of years, every project is so shocking that the viewers feel excited and heavy.

Farmers who go to do corvee every year sigh empathetically: "The people of future generations will have to do too much corvee..."

Just for a fish scale pit, you have to build the pit with stones by hand, then transport soil from the bottom of the mountain, and finally plant trees. There is as much work as there are pits on a hilltop.

Someone retorted: "But they turned the loess green."

"Then their land is planted with trees and no other crops can be grown randomly. What will happen to the food?"

"They have their own high-yielding hybrid rice."

By the end, everyone fell silent.

["Whether it is large-scale afforestation or the protection of natural forests, the first priority is to control desertification..."

Professionals from the Agriculture and Forestry University led a team to dig out the soil at different depths with shovels, package and label it, and then performed different delicate operations in the laboratory to test the temperature and humidity of the soil...]

Taking out the compiled professional materials on soil and water conservation and desertification prevention, many people had an intuitive feeling about the profession that they had heard vaguely in the morning.

"This is the previous job of the water conservation major..."

People who used to laugh at the fact that they had to spend too much time studying and farming have stopped talking. There is so much knowledge in just digging the soil, which is completely different from what they thought of farming, and what they do is actually for this purpose. No matter how hard you pay on a piece of loess land, it cannot be compared with a lowly career.

[A desertification control expert wearing blue short-sleeves sat in the research institute and said: "There are currently more than 100 million acres of Pinus sylvestris planted in Yulin, and there are still some problems. For example, the natural regeneration of Pinus sylvestris has not been realized. Excavation Regarding desert plants with economic value, we are doing some projects so that people in desert areas can enjoy the fruits of desert control while controlling desertification."

"On March 2008, 3, Shaanxi Province began to implement the policy of mountain closure and grazing prohibition. Most of the herdsmen in Yulin have completed the transition from grazing to raising sheep..."

Fresh grass is put into the machine and cut into small chewable grass pieces. The herdsmen mix it with other feed and feed it to the lambs in the sheepfold.

Despite the grazing prohibition policy and the grazing prohibition team members, private grazing still occurs. The team members who receive the report need to get off the car and climb the mountain to find the old man grazing. ]

"Closing the mountain to grazing, how can we manage such a big mountain!"

"They have that drone. Let's see if they can catch the private herders."

"Report hotline? The land is so green, can't we let the sheep eat it..."

"Sheep eat grass because they eat the roots. If you let the sheep eat it, the green grass will be gone soon!"

Many people have begun to argue about the grazing ban policy. People who once only focused on farming have unknowingly begun to debate the merits of the policy.

And some people see the difference between these law enforcement officers.

[Before going on a mission, they would make sure each other would not hurt anyone. They drove up the mountain and caught the old private herder who was sweating profusely. His attitude was also very kind. He also had to take out his ID to confirm his identity and read the policy to others.

The old man herding sheep didn't panic even if he was caught. He could still talk to the team members in his local accent.

The old man who was leaning on the wooden stick and not nervous at all, and the team member who was sweating and squatting on the hillside, took out a manual and read the laws and regulations to the old man, did not know who the official was for a moment. ]

The villagers who had never been out of the house clucked their tongues: "Is this an official for future generations?"

Li Zheng, who had led the villagers to hand over grain to the officials, shook his head: "Which official would go all the way from the city to the mountains just to catch someone secretly herding sheep?"

Villager: "But those policemen who collect grain are not like this..."

Legalists are puzzled. The shepherd broke the law and should be punished as a warning to others. Why don't those responsible for supervising this matter do anything? If this goes on without punishment, what is the point of laws and policies?

[The land of loess is dyed green, and water flows are beginning to nourish it. Eco-tourism and forest specialty industries have begun to grow in many areas of northern Shaanxi.

Young guys wearing white scarves and holding red silk in their hands beat the waist drum. At night, from the city with flashing lights to the countryside with small lights, everything is so peaceful and beautiful. ]

Under the canopy, young people in the northwest region took courage.

"Elm trees, poplar trees, salix trees, caragana trees, polygonum root trees, Leedang trees, Dishao melon trees, as well as Pinus sylvestris, Sophora japonica and Sadawang trees. I remember them all. The village chief, can the descendants on the sky screen remember them all?" If we can do it, we will do it too!”

The village chief looked at these young people, with a flash of relief on his weather-stained face, but he also asked realistically: "Where did the tree seeds and saplings come from? Is that Scotch pine or something from the grassland? How do you plant it? They still have their own The support of the imperial court and the support of professional scientists, what about us?”

"Then we have to do it!" The young man said with determination: "If you can't go out, then I will find living trees here, plant them alive, and plant more!"

The village chief asked again: "What should I do with the food?"

"After planting food, plant trees. Plant trees around the land you plant!"

More than one person thinks this way, everyone living in this piece of loess thinks this way. Before Tianmu, they knew nothing and thought that the land they had lived in for generations was like this, but Tianmu told them that this could be changed.

They are not as rich and powerful as the later generations, but they also want to change the land in which they live.

Niu Yuqin said that people can't be bullied to death by the sand, but can they be bullied to death by this land?
