Due to the large number of impurities in the poor iron ore, and the use of coal for coking, there are always some elements of sulfur and phosphorus left in it, and the iron produced by this blast furnace is not suitable for direct weapon manufacturing. Pen ~ fun ~ pavilion www.biquge.info

And yet the impact is enormous! Because its production is so large that it can directly turn the price of iron into the price of cabbage.

For the iron produced, Dai Yan made most of it into agricultural tools and sold them in all directions.

The first to benefit were the farmers of Xiangyi, Fengyi and Taoqiu.

When Dai Yan was still in Fengyi, he was worried about the high price of wooden plows and copper farm tools. In his view, the simplicity of agricultural tools is definitely the primary factor restricting the development of agriculture towards intensive cultivation. Therefore, when there was a sufficient amount of iron, Dai Yan immediately ordered the disciples of the peasant family to recycle all the wooden plows sold to the peasants, and replace all the plowshares in them with iron plowshares for free, which greatly increased the efficiency of the peasants' ploughing.

He then started the recycling of copper tools throughout Fengyi. First of all, he announced to the common people in Fengyi that there would be a large number of iron farming tools for sale in the whole of Fengyi, which were the same as the newly replaced iron plowshares. This kind of iron farming tool will be sold to everyone at a very low price, but the eupp will only accept five baht money, and the common people need to exchange the copper tools in their hands for five baht money if they want to buy it.

After a few years of Dai Yan's rule, the common people of Fengyi have long had no doubts about the orders of the Yi Mansion! Therefore, as soon as they heard that there were iron tools for sale at very low prices in the eup, the common people exchanged the copper tools in their hands for exquisite five-baht coins without saying a word.

Subsequently, a large number of iron tools were transported to Fengyi and began to be sold to the whole of Fengyi.

The common people had been reminded by the Eupon that the price of iron tools would be low, but when these tools were placed in front of them and actually sold to them, they could hardly believe their eyes!

an iron sickle, two coins a piece; Iron hoe, three dollars a handful; Shovel, five dollars a handful! Almost all iron tools cost more than 10 yuan!

This made the common people of Defengyi feel unbelievable! You must know that the copper farm tools in their hands can be exchanged for five baht at any time, and they can be exchanged for at least a hundred dollars. Doesn't this mean that the original copper farm tools in their hands can be exchanged for dozens of iron farm tools at will?

Iron is a thing that the common people of this era still know more or less about it, and they also know that it is evil gold. It is indeed inferior to copper tools in terms of corrosion resistance and quality, but it is "gold" after all, not stone!

Even if these iron farming tools are easy to damage when they are bumped, it is impossible to cut the grass and turn over the soil to break it, right? Therefore, this low-cost iron farming tool was immediately welcomed by farmers!

In fact, this practice also had another unexpected effect, and from then on, the farmers of Fengyi were accustomed to buying and selling goods with five baht coins, rather than holding various coins or even trading directly with copper.

Dai Yan concocted this practice in the same way around Taoqiu, which immediately made the farmers around Taoqiu crazy. Xiangyi, on the other hand, is located in the origin of iron, so they also share the benefits of large-scale iron production like the farmers of Fengyi and Taoqiu!

As for some by-products of coking, crude ammonia, Dai Yan also refined it into a small amount of nitrogen fertilizer. Nitrogen is the most important element for plant growth, and Dai Yan also sold all these nitrogen fertilizers to farmers at low prices and applied them to the land of Fengyi and Taoqiu, which immediately quadrupled the agricultural output of the two places this year!

"It's a pity that I can't break through the technology of synthetic ammonia under today's technical conditions, otherwise I would be the first person in Chinese history to break the 'Malthusian trap'!" Seeing the great effect of nitrogen fertilizer, Dai Yan also thought with regret.

In later generations, the Celestial Empire can feed 20% of the world's population with 7% of the world's arable land, and even ensure that the per capita consumption of eggs, poultry, meat, aquatic products, and fruits exceeds the world's advanced level. Some ignorant people appealed in the newspapers, and even suggested to the Ministry of Agriculture: "I am a brilliant empire with vast resources and such a high agricultural yield, can we use more farm fertilizer without chemical fertilizers, and let us eat more 'green' and 'natural' things." In response to such an appeal, the Ministry of Agriculture can only spread its hands: "According to your suggestions, I am afraid that the grain output of the entire Celestial Empire will be cut in half immediately!" The entire Celestial Empire, just get ready to starve half of the people to death first! ”

Such a statement is by no means alarmist, but is based on facts! After World War II, North Korea was embraced by the Soviet Union and the Celestial Empire, which provided the Soviet Union with cheap oil resources and established a complete chemical system that could produce sufficient amounts of fertilizer. As a result, the whole of Korea had an excellent economic development after World War II, and only Japan could compare with it in the whole of Asia! And in the eighties, before the collapse of the Soviet Union, the North Korean leader proclaimed all over the world: "We have built a modern socialist republic!" That was true at the time. Compared with South Korea in the south, North Korea was more like a developed country at that time! As a result, as soon as the Soviet Union collapsed, it lost its cheap oil, and North Korea's chemical system collapsed directly. Because of the lack of sufficient chemical fertilizer, in the 90s, when the northeast of the Celestial Empire had a bumper harvest year after year, North Korea fell into a serious famine because of the "natural disaster", and hundreds of thousands of people were directly starved to death, and in the 90s, one-third of the people in the entire country fell into a state of malnutrition directly because of hunger!

Dai Yan really wants to establish a chemical system, if there is a complete chemical system, grain production has increased several times, in this era of war is to fight grain, there is absolutely no country is his opponent!

The reaction of ammonia synthesis system in the chemical system is extremely simple, that is, hydrogen and nitrogen are used to generate ammonia directly under the reaction of high temperature and high pressure and catalyst. This simple chemical reaction can be recited by Dai Yan with his eyes closed. However, the three conditions for ammonia synthesis, high temperature, high pressure and even the selection of catalysts are not simple! Not to mention anything else, just to achieve high temperature and high pressure conditions, I don't know how high the requirements are for the steel of the reactor! With Dai Yan currently only able to refine inferior pig iron, how could he reach such conditions when the material industry is so low!

However, from the nitrogen fertilizer incident, Dai Yan also got inspiration from this: the ideal of establishing a chemical system still needs to exist, what if it is realized?

He carefully thought about the benefits that can be obtained by establishing a chemical system, as well as the difficulties that need to be faced, and he knows that this is definitely a huge profit, and the difficulty is also very large. Therefore, Dai Yan began to divide into several steps to start overcoming this problem.

He first put forward the concept of "chemistry" in the scientific school, and this time he did not hide it, but told all the chemical knowledge he knew, thus constructing a simple chemical system. Such an approach is certainly not conducive to the long-term development of chemistry, but he can't care about it so much.

For the verification of chemistry, he just asked the disciples of the scientific school to do experiments separately. After they verified the entire chemical experiment and confirmed the correctness of Dai Yan's theory, Dai Yan divided his most elite disciples into two groups, one group specialized in studying materials and trying to make qualified steel; Another group studied chemical reactions and tried to find a suitable catalyst.

Dai Yan bluntly said to these two groups: "Your research is related to the well-being of hundreds of millions of people! If it can be successfully studied, then there will be no more famine in the whole world, the wars between countries for land due to lack of food will disappear, and the ideal of 'non-offensive' can be truly realized in the land of China! ”

I have to say that if for a study, after imbuing with ideals, people do become different. Knowing that their research was so important, almost all of the people involved in the research forgot to sleep and eat their work, and fell into this obsession for decades!

Even Dai Yan later speculated: Did the scientists who studied the "two bombs and one satellite" in later generations also have such an obsession like them?

And Dai Yan quickly reaped considerable benefits from their research. In order to "cooperate" with their research, Dai Yan set up a special steelmaking plant near Taoqiu, transferred all the pig iron that was not made into agricultural tools in Xiangyi to this place, and began to study how to make pig iron into steel!

And even without a chemical system, the low-cost sale of iron farm tools itself caused an agricultural revolution!

When iron farming tools were sold to Dai Yan and the common people of Xiangyi at a low price, the merchants in the Song Kingdom were moved by the news and went to Xiangyi to start purchasing iron farming tools in large quantities, and then sold them to the entire Song Kingdom. The farmers have been given a large number of cheap iron farming tools, and the new cultivation in agriculture has really become possible, and the production efficiency has also been greatly improved! In that year, the grain output of the entire Song Kingdom directly doubled, and the fiscal and tax revenue of the Song Kingdom that year also increased significantly!

This is the huge impact that the development of industry has had on agriculture!

Although the merchants and farmers knew what the cause of the incident was, in the eyes of the high-level leaders of the Song Kingdom, who believed in ghosts and gods, this was the blessing of Haotian God! After worshipping the gods more humbly for such a bumper harvest, they continued to increase the exploitation of the common people at the bottom!

The dividends of the agricultural revolution in the Song Kingdom were not enjoyed by the common people at the bottom!
