After listening to Yang Fang's introduction, Wu Hao and Zhang Jun looked around and compared. Indeed, the bamboo forest here after artificial intervention has grown more luxuriantly, and the plants are denser, and they have basically covered the sand on the ground. The bamboo forest over there has grown completely naturally without artificial intervention. The height of the plants is smaller, which is obviously a bit lower than here, and you can also see the exposed yellow sand.
"The difference is obvious. Although the growth here is better, the cost of manual intervention will probably be very high." Wu Hao nodded, then looked at Shen Ning and asked.
After hearing Wu Hao's inquiry, Shen Ning immediately replied with a smile: "Actually, the cost is not high. The first is the cost of fertilizer. On average, it costs more than one hundred yuan per mu of land. Ten thousand acres is only about one million yuan. .
You don’t need too much water source. You only need to water some water during the bamboo shoots’ germination stage every year. The cost is actually not very high.
Of course, if it is one million acres, ten million acres, or one hundred million acres, it is not a small number. So in the long run, this kind of bamboo forest that grows naturally without artificial intervention is more economical. "
"I can't say which way is better, it depends on the actual needs."
After hearing this, Yang Fang immediately shook her head and said: "The natural forest growth rate is slow and the quality is poor. It cannot quickly meet the relevant requirements. Especially in wind prevention and desertification control projects, this beginning is the most important.
Using artificial intervention, you can first cultivate some protective isolation belts to isolate the wind and sand, and then use the plants in the square grid composed of these isolation belts to let them grow naturally. This mixed method is more reasonable and more capable. Meet the requirements."
After hearing Yang Fang's words, Wu Hao and Zhang Jun couldn't help but nodded. Indeed, there is no better way, only that way is more suitable.
Besides, even if all of them adopt this manual intervention method, the cost itself is not expensive and is within an acceptable and reasonable range.
We add fertilizer, water, seedlings, and planting and maintenance costs per acre, which adds up to about 400 yuan. Ten thousand acres is only 4 million, 100,000 acres is 40 million, and one million acres is 400 million. Ten million acres is worth 40 billion, and 100 million acres is only 40 billion.
You know, our country’s red line for cultivated land is only 1.8 billion acres. We only need to spend 40 billion to own 100 million acres of high-quality forest land. This is a great deal.
Even if calculated based on the land red line of 1.8 billion acres of forest land, it is only 720 billion, which seems a bit much, but in actual calculation it is simply too cheap.
You know, 100 million acres of forest land is 67,000 square kilometers, and 1.8 billion acres is 1.2 million square kilometers. What is the concept? It is almost the area of a Tibetan province, which is equivalent to ours. Almost one-eighth of the entire land area.
The economic and environmental benefits it generates are much higher than the 720 billion, and the overall calculation is simply worth the money.
Of course, this is just a comparison. No one said that it is necessary to plant a bamboo sea as large as Tibet Province. This is obviously not practical. But in total, even if it costs one trillion, it can reduce the desert in our country. Once all afforestation is completed in arid areas, this trillion will be well spent and benefit future generations.
However, the desertification control project cannot be realized overnight. It is a long-term project and we cannot complete it at once. This is obviously unrealistic.
This project will take a long time. It starts in ten years, and may be twenty, thirty, fifty, or even one hundred years. As long as we persist, one day the Gobi desert will disappear from our domestic territory. .
Of course, it may not take that long. With the application of new technologies, especially the application of plant gene editing technology of Haoyu Agriculture, there may be a very big change in Northwest China in ten or twenty years.
After hovering in the air for a few more times, Wu Hao then pressed his hands and said, "Go down."
"Okay!" Shen Ning responded and immediately communicated with the pilot.
Soon the helicopter flew to a raised steel platform deep in the large bamboo forest and landed. Wu Hao and the others faced the strong wind from the helicopter propeller, bent down and got off the helicopter, and then left the plane. .
The helicopter did not stop, but lifted up gently, and then flew away, and the scene immediately returned to silence.
Shen Ning took the opportunity to introduce the situation here with a smile at Wu Hao: "This is a helicopter landing platform we distribute in the forest area, used for helicopter landing. After all, this forest area is too It is too big to be easily accessible and difficult to manage. Therefore, in daily life, we use helicopters or drones to conduct inspections and management.
At the same time, these platforms are also our foothold when entering the forest area, so that we can often enter the forest area to observe the internal environment and conduct related work."
Wu Hao nodded, and then he and Zhang Jun came to the edge of the platform. At first glance, they were surrounded by green bamboo shoots. And the heights of these bamboos were actually about the same, so the bamboo shoots were basically the same height. Looking from a distance, it looked like Like a lush green grassland, it stretches as far as the eye can see.
Under the breeze, these bamboo shoots sway slowly, and the breeze contains some fragrance of bamboo.
"It's so comfortable!" Zhang Jun couldn't help but sigh as he spread his arms and felt the breeze.
Wu Hao smiled and nodded: "It's very good. Those who don't know would think we are in the Bamboo Sea in the south of the Yangtze River."
"Yes, we all felt this way when we went deeper. If it weren't for the yellow sand under our feet that reminded us, we really thought we were in Jiangnan." Shen Ning replied with a smile.
Wu Hao nodded, then waved and said, "Let's go down and have a look."
Immediately, everyone slowly walked down the iron ladder. Although it was not a straight up and down ladder, this iron ladder was still very steep, and the stairway was very narrow and could only accommodate one person.
Walking down the stairs, Wu Hao and the others put on the shoe covers given by the staff to prevent sand from entering the shoes. In addition, this shoe cover is also a kind of protection to prevent mosquitoes from getting in. Especially in this desert forest area , there are various snakes and insects everywhere, such as the most common red scorpion, and some venomous snakes, etc., all of which like the moist environment of this forest area very much.
The entire platform is surrounded by lush bamboos, and bits and pieces of light shine through the bamboo tops. However, it is very cool on the whole, and there is no heat from the sun on the platform.
With the platform as the center, several trails radiate out from all sides. The trails are very narrow and you can see that they are created by the staff who often walk on them.
