Ultra-Dimensional Technology Era

The current situation means that their submarine has completely lost its concealment. For the soldiers on the submarine, this is a very terrible psychological pressure.

A submarine without concealment = an iron coffin.

Who wants to drive a submarine that is doomed to sink? Obviously, no matter how nervous the person is, every time he performs a mission, it is frightening.

It's okay for a short time, but once in this depressed mood for a long time, it's no wonder the soldiers don't have a nervous breakdown.

For this matter, Guam and Yokosuka had to hold an emergency meeting to discuss how to deal with it.

the other side.

The Wang Jian has broken through the international date line and entered the waters of the Eastern Pacific Ocean.

Anyway, this is the high seas, I can sail however I want, and no one can stop the Wang Jian.

"Report, we are approaching Johnston Island."

Lei Baiqin looked at the data and found that Johnston Island is another secret base of the G organization in the eastern Pacific Ocean.

Sailing along the line again, and like the previous Rota Island, sailing around the island first sticking to the line, and then leaving swaggeringly.

The mission of Wang Jian this time is to sail around the island of the G organization's base in the Pacific Ocean.

Other forces may not know what this is doing, but the G organization definitely already knows the intention of the Nether Palace.

After all, the first time sailing around the island was an accident, but the second time it was not an accident, it was definitely intentional.

Next, the Wang Jian arrived at Millennium Island in the southeast Pacific Ocean, Rapa Island in the South Pacific Ocean, Norfolk Island in the Southwest Pacific Ocean, and Solomon Islands in the Western Pacific Ocean, and sailed around the islands.

The G organization did not expect that the Netherworld had figured out their various secret bases in the Pacific Ocean.

This kind of voyage around the island, and the dispatch of the battleship Wang Jian to sail around the island, is obviously to remind the G organization that I have found you.

Chapter 241 Rock Formation Advancement

Look back to the country.

Yang Bai, the chief researcher of the rock-forming laboratory, and others are near the estuary of the Liao River in Panjin City, Liaodong Province.

The seawater desalination plan of last year and this year has initially satisfied the North China Plain, Guanzhong Plain, and about 46% of the Loess Plateau area.

Beginning in September, Yang Bai and engineers from the seawater desalination management company came near the mouth of the Liaohe River.

In fact, there are not many water resources in the Northeast. In addition, the Liaohe Plain, Songnen Plain, and Sanjiang Plain in the Northeast still have very serious problems - land salinization, soil erosion, and land desertification.

It seems that the water resources in Northeast China are good, with a total of about 2000 billion cubic meters. However, as a large agricultural region in Northeast China, the annual agricultural consumption of water resources is as high as hundreds of billions of cubic meters.

The total amount of regional water resources does not represent the total amount of available water resources. In fact, 30% of the total amount of water resources that can be used has almost reached the peak.

Where does the rest of the water come from?

Of course, the mining of groundwater and the large-scale and long-term use of groundwater to irrigate farmland will cause land salinization. In addition, many farmlands use excessive chemical fertilizers, which further deepens the degree of land salinization.

Because the content of mineral salts in groundwater is relatively high, after irrigation of farmland, mineral salts will slowly accumulate in the soil, forming a layer of "salt crust", which will cause land compaction and make it difficult for crops to grow.

Excessive land reclamation will lead to a rapid decline in the natural fertility of the land, which in turn will lead to land desertification and soil erosion, which will prompt farmers to increase the use of chemical fertilizers and deepen the degree of land salinization. This is a vicious cycle.

At present, the land salinization area in the Liaohe Plain is about 30%; the land salinization area in the Songnen Plain is about 75%, and the desertification area is about 50%; the land salinization area in the Sanjiang Plain is about 10%.

It can be seen that the land conditions in the Northeast are not much better than those in the Northwest, and even worsened at a faster rate due to the impact of excessive land reclamation.

So how to solve land desertification and land salinization

The most simple and crude way is to return farmland to forests and grasslands.

However, the possibility and feasibility of this is very low. As an important commercial grain and commercial soybean planting area in China, it is impossible to convert farmland to forests and grasslands on a large scale in the Northeast.

However, in the past few years, the situation in Northeast China has improved greatly, which is benefited from the promotion and development of rural cooperatives and large greenhouse farms.

After all, a lot of land has been directly built with glass greenhouses or agricultural buildings, so that soil erosion can be curbed.

In addition, refined chemical fertilizers and drip irrigation technology have further suppressed land salinization.

However, the problem of over-exploitation of groundwater has not been completely resolved. Only by solving the problem of using groundwater for irrigation and irrational use of chemical fertilizers can we fundamentally curb land salinization.

Due to the experience of saline-alkali land transformation in the North China Plain, it is currently a general saline-alkali land transformation plan, which was developed by the Agricultural Saline-Alkali Land Research Institute of the Academy of Engineering.

In the first step, use fresh water (close to pure water) to flood the plants 5 times, each time for about a week.This step can dilute and dissolve the mineral salts in the soil, and then carry them away with the river.

The second step is to use livestock manure, kitchen waste, and dead branches and rotten leaves of plants to make organic fertilizer, and add these organic fertilizers to the soil of the farmland through deep plowing.

In this way, the soil transformation of the saline-alkali land can be completed initially, and then gradually adjusted with fresh water flood irrigation and organic fertilizer during the cultivation process year by year.

In terms of organic fertilizers, Huanong Group collects them regularly from farms, pastures, farms, and rural cooperatives across the country, and then concentrates them into organic fertilizers.

The only problem now is water.

So the seawater desalination management company and the rock-making laboratory were ordered to come to the mouth of the Liaohe River to build a seawater desalination plant.

After a large number of new humans joined, the desalination management company and the rock-making laboratory have become very powerful.

Next to the construction site of the desalination plant is a water transfer plant.

But at this time, the water delivery plant is directly pumping seawater from the Bohai Sea, which is directly used to make water pipelines.

These water pipelines have now extended more than 30 kilometers to the north, and the speed of advancement is very fast.

After all, to directly generate pipelines with rock-forming agents, it only needs to bind the steel skeleton in advance, and with the special mobile pipeline formwork, the pipeline manufacturing speed is very fast.

It is not a problem to advance more than ten or twenty kilometers a day, unless you encounter complex terrain such as mountains.

The excavator excavated large pits, and the crane quickly put the steel frame of the base into the pits, and then the formwork was closed.

The next step is to arrange the inner formwork of the pipeline, the steel frame of the pipeline, the outer formwork on the base, and tie the calculated rock-forming agent on the steel frame.

After laying about ten kilometers, an engineer pressed the water switch.

From the last gate valve, a large amount of seawater rushed to the outlet of the pipeline and poured directly into the formwork. The seawater and rock-forming agent reacted quickly, and the artificial rock began to fill the steel skeleton. In less than half an hour, the pipeline was formed.

This is the charm of science and technology, a weapon that can change the world in the hands of believers in the truth.

"Han Chao, how is your arrangement going?" Yang Bai asked.

Yu Hanchao, who was looking at the adsorption box, raised his head and said back and forth: "16 kinds of adsorption boxes have been arranged, and they are all the latest versions of adsorbents."

Yang Bai asked curiously: "I heard that a lot of gold and silver have been extracted from sea water recently!"

Yu Hanchao is in charge of the seawater trace element extraction process, while Yang Bai is in charge of the seawater macroelement extraction process.
