Chapter five hundred and fifteen large-scale projects
The seemingly inconspicuous bristles have had such a big impact, not to mention important rare metals such as tungsten and rare earths. The United States is rich in mineral resources, so it will be a little uncomfortable at the beginning. As long as the mining intensity is increased, it will be within a year at most.
It can completely fill the gap, but the United States can only guarantee that it has enough of these rare metals, and cannot have too much balance for export, so life for Britain and France will be difficult.
For China, a major agricultural country, the production of chemical fertilizers and pesticides is extremely important, so it has long been highly valued by Hu Weidong. The chemical fertilizer industry has developed particularly rapidly. The total output in 1940 was close to 1.2 million tons, enough to satisfy 80 million acres.
Although the demand for grain fields is still far from the day when all farmland across the country will use chemical fertilizers, it was enough to set a new historical record for the country's total grain output in 1940, and the annual output of other major agricultural products such as cotton was also generally
Hit a record high.
In addition, the rapid increase in pesticide production and the widespread construction of farmland water conservancy infrastructure across the country, coupled with the widespread establishment of cooperatives, are conducive to organizing efforts to prevent and fight disasters, greatly reducing the impact of natural disasters, and are also important factors for the great agricultural harvest in 1940.
One of the reasons.
Compared with other years, the development of industry and agriculture in mid-1940 was only qualitatively and quantitatively different, while the construction of large-scale projects was almost the same as "have" and "". Previously, due to the ongoing Anti-Japanese War, the situation was still unclear, and the Red Party
They do not dare to invest too much effort in the construction of large-scale projects, including the Yanguoxia Hydropower Station, the Lanzhou-Xinjiang Railway and several short-distance railways in the Central Plains Liberated Area connecting mining areas and central cities.
But by 1940, the complete end of the civil war gave the Central People's Government the stable environment and human, financial and material resources to carry out large-scale construction projects. Coupled with German assistance and the guidance of high-end talents hired from abroad, a number of world-class large-scale
Projects have been launched one after another. In addition to the coastal deep-water ports and large-scale shipbuilding docks mentioned above, Lanxin
In addition to railways, roads into Tibet (the number has been increased to 4), Yanguoxia Hydropower Station, it also includes the reconstruction and expansion project of Manman Hydropower Station in Northeast China, the Liujiaxia Hydropower Station in the upper reaches of the Yellow River, the Baocheng-Chengdu Railway, the Chengdu-Kunming Railway, the Chengdu-Chongqing Railway, and the Wuhan Yangtze River
Bridge, Sanmenxia Yellow River Bridge, Yellow River Control Project, Huaihe River Control Project and other more than 30 large-scale engineering projects.[
The amount of human, financial and material resources invested in this end is rarely seen in human history. Even though the national system has various flaws, it is doubtless a shortcut to realize China's modernization under the current situation of China's desperate situation and weak foundation. And it is consistent with history.
Compared with the above, China currently has a great advantage, that is, agricultural machinery and pesticides
The production of chemical fertilizers already has a good foundation. It can greatly improve agricultural labor productivity and agricultural output. Therefore, even if there is a large-scale construction project, it will not cause famine because of the impact on agricultural production. On the contrary, it can absorb a large amount of land that is idle due to the increase in labor productivity.
out agricultural labor.
Of course, it must be noted that since many projects need to be investigated and approved first, they will not all start at the same time. Otherwise, even with China's manpower, it will still be a bit overwhelming when the war in the southwest is not over yet. And among them, Liujiaxia
Water conservancy projects such as hydropower stations, Yellow River control projects, and Huaihe River control projects are of great significance to agriculture, among which the Yellow River control project and the Huaihe River control project are of particularly great significance.
When it comes to managing the Yellow River, history has gone through a detour after the founding of the People's Republic of China. As early as the Ming Dynasty, our ancestors had already proposed the clever strategy of "confining water and flushing sand." However, most Chinese hydraulic scientists at that time
Believe in the views of Soviet experts and reject the correct opinions of a few sober people
The government mistakenly suggested that the central government build the Sanmenxia Reservoir, which resulted in serious siltation of the reservoir and the upper reaches of the river. Not only did it fail to control the sediment problem in the Yellow River, but it actually made the problem more serious. It made the subsequent comprehensive management of the Yellow River very difficult, and it was a waste of human and financial resources.
The material resources are even more amazing.
Now that Hu Weidong, a time traveler, is in charge of the overall situation, he will naturally not make the same mistake again. The construction of the Sanmenxia Yellow River Bridge first will eliminate the possibility of building the Sanmenxia Reservoir. Although the scientific and technological conditions are not yet met, later generations will build on information.
The "water and sediment regulation" strategy based on chemical technology cannot be effectively implemented for the time being, but through manual coordination, it is still possible to partially achieve "water and sediment regulation", but it is not as convenient as under information technology.
The effect will definitely be worse. The core of his thinking - the idea of using the Yellow River water to wash away the sand in the Yellow River is generally accepted because of Hu Weidong's unparalleled prestige in China's scientific and technological circles. Therefore, the newly built reservoir dam and Yellow River embankment are both
Following this idea and properly laying out the system, once the system is fully completed, as long as the conditions for informatization are met, it can quickly reach the level of the "water and sediment regulation" project of later generations. This can be regarded as a precautionary measure.
However, the construction layout of water conservancy projects is a long-term consideration. In order to avoid immediate problems, the reinforcement of the old Yellow River embankments cannot be ignored. But at least the Yellow River has embankments. In contrast, floods are formed because the downstream is silted and cannot enter the sea.
Zehu Lake, the Huaihe River, which has no dams to block it and therefore frequently floods, is the biggest disaster in China today.
Since Hongze Lake is formed by the siltation of river water on the plain, it is large in area and shallow in water, which is very different from normal lakes. It often dries up in large areas during droughts, and easily floods when it rains. The Huaihe and Huaihe areas
The common people call it "heavy rain disaster, light rain disaster, rain drought disaster." It is not like a natural lake at all.
The moor has the function of regulating the climate and reducing floods and droughts, but it makes the people of Huaihei and Huaihe suffer greatly. In order to get rid of this scourge once and for all, Hu Weidong is determined to let it completely disappear from the earth, which can also open up large tracts of fertile farmland.
, this is much greater than the food output of the Hongze Lake fishery.
In fact, the first generation of leaders of New China may not have had this idea in history. At that time, China was poor and backward, and water conservancy construction basically relied on manpower. The work efficiency was too low, and it was impossible to complete the restoration of the Huaihe Ancient Road (note
1), there is a grand plan to drain Hongze Lake, and if the Huaihe River control projects such as the Northern Jiangsu Irrigation Canal are completed, the cost will be too high if it is changed again.
Note 1: The ancient river channel no longer exists. If you want to restore it, you must dig it again. For a large river like the Huaihe River, if there is only one main channel entering the sea, you must dig a channel that is wide and deep enough. This amount of work
It was too big for China at that time, and it was far less divided into multiple canals than the Northern Jiangsu Irrigation Canal.
The plan to release water through a channel is practical, but in terms of the amount of water released, a wide and deep main stream is more effective, and it can also benefit from shipping. (To be continued. If you like this work, you are welcome to come to Qidian
