The prince's business was not a top national event in the Qing Dynasty, but it was a very important thing in the eyes of Emperor Kangxi. The pen %fun %Pavilion www.biquge.info often used the excuse of coming to the house to taste the new dishes of his aunt, and mentioned exotic things to the prince. In fact, he is interested in how to rejuvenate the country in a foreign land. Such a big country doesn't even have an emperor, needless to say anything else, that is, how the common people solve the problem of eating is a considerable problem of the national economy and people's livelihood.

The prince told him that most of the grain in foreign lands was grown with chemical fertilizer, because there were too many people, and high-yield grain must be sought, and the grain crops that used chemical fertilizer were all more than 1,000 catties per mu.

Kangxi was very happy: "Why didn't Uncle Huang bring back the method of how people make fertilizers?" ”

"It's not that the minister doesn't want us to get more grain on the land of the Qing Dynasty, it's that the pollution of the land by chemical fertilizer is very serious, and the land that has used chemical fertilizer no longer uses chemical fertilizer, not only can not have a high yield but will reduce the yield. The land area of our Daqing Dynasty is about the same as that of foreign lands, but the population is less than one-tenth of that of people, and there is no need to use chemical fertilizers at all. ”

"You said that there are 1.3 billion people there, and the food is solved, what about the salt?"

"I know a little bit about the salt ministers over there, whether they are officials or ordinary people, they all eat powdered seaweed iodized salt, and there is no shortage of salt at all. There is also no talk of selling illicit salt. Seaweed iodized salt is a pure natural biological iodine supplement product made of refined salt as raw material, reasonably added seaweed iodine, and refined in strict accordance with the standards. Refined salt, also known as fine salt, is the salt that crystallizes after removing impurities, with few impurities, and some trace elements are also removed after processing, and sometimes iodine is added to specially prepare iodized salt to prevent thyroid disease. Common thyroid diseases include thick neck disease, also known as goiter, and hyperthyroidism, the former is caused by iodine deficiency in the body, and the latter is caused by excessive thyroid hormone secretion. To prevent thick neck disease, you should eat iodized salt and eat more marine animals and plants such as kelp, seaweed, jellyfish, etc. Hyperthyroidism has symptoms such as nervousness, irritability, excessive speech, excessive thinking, and excessive hunger. After the diagnosis is confirmed, the doctor will recommend oral antithyroid drugs, extra vitamins, and surgical removal. This seaweed iodized salt includes iodine and seaweed for the prevention and treatment of thyroid disease, but there is also a certain proportion of iodine and seaweed added to it. The retail price of seaweed iodized salt in foreign lands is uniformly set by the state, so as to prevent the hoarding of salt merchants. ”

Emperor Kangxi was deeply shocked by the prince's words: The government over there really thinks about the people, so that the people can eat seaweed iodized salt without growing thick necks.

"We should be able to learn from other people's methods of producing and managing salt, right?"

"Your Majesty, the old minister knows that you are for the prosperity of the country and the prosperity of the Qing Dynasty. However, our production methods and manufacturing equipment cannot be compared with others, and some things are not easy to learn from. For example, their manufacturing equipment is complete, and the price is quite expensive, and the money in the hands of the old minister is not able to buy a small part of the family. Even if you buy it, you won't use it because you don't have the know-how to do it. Every line there is deep and complex. Let's talk about the production of seaweed iodized salt, when refining coarse salt into fine salt, a certain amount of trace elements must be added to it, and it must be filtered with something called activated carbon, and seaweed and iodine must be added. Lao Chen was very ashamed, although he also read some books after he was still vulgar, he was actually illiterate who had never gone to school. Besides, all the manufacturing industries, many disciplines, and even everyday life over there are inseparable from electricity. Electricity alone is a very complex subject, and an engineer in the field of electricity has to read at least 20 years. Besides, our Qing Dynasty and the Exotic Land are two social systems, and all walks of life are completely different management methods, and the way of business operation is also completely different. ”

"Oh? Can you talk about that? ”

"Lao Chen only knows that the salt of our Qing Dynasty is operated by the government, and we buy it at a low price and sell it at a high price, so as to ensure financial revenue, prevent salt merchants from hoarding, and maintain social stability. But this approach is often blamed for competing with the people. The salt of our Qing Dynasty mainly includes sea salt, well salt, and rock salt. The main production areas of sea salt are Shandong, Jianghuai and Songhu, which are near the sea, the production area of well salt is in Sichuan, and the production area of rock salt is in Shanxi. The old minister didn't know much about how we produced salt in the Qing Dynasty, but the imperial court had a rule that ordinary traders could not sell salt. The management of salt in foreign lands is called unified purchase and sales, which seems to be the same, salt is also managed by the state, and the price is uniformly regulated by the state, but the output of salt produced by people is large, the production cycle is short, and there is no shortage at all, so that hoarding can not occur. Salt can be sold by small and large vendors, from small grocery stores to supermarkets of large merchants. All of them are bagged seaweed salts produced at a unified price and at a unified price by the state. No matter what the business name is, the retail price is one dollar per bag. Most of them are extracted from seawater, and they are all dried salt by seawater. ”

"Didn't you, my little aunt, and Uncle Tian bring back the detailed method of drying salt in seawater? If the salt production of our Qing Dynasty is large, and it is also purchased and sold by the state, there will be no hoarding and spontaneous windfalls of salt merchants, and there will be no trouble with salt. ”

"Your Majesty, when the three of us first arrived there, our eyes were completely black, and we couldn't cope with a lot of daily life there, and if it weren't for Master Gan Lin entrusting us to his friend Sister Han, we wouldn't even be able to find a place to eat. Where did you think about table salt? Your little aunt is a woman, and her energy is focused on learning how to cook and wear food, and the old minister follows the eldest sister's husband to learn how to plant trees, flowers, and beekeeping. Mr. Tian learned some simple equipment use and how people manage the business. Lao Chen saw the word sea water drying salt on a TV show, just a few simple words. I don't know if your little aunt and Mr. Tian have heard the eldest sister talk about the salt, and I turned around and asked them, even if the quality of the production is not as good as others, we can also try it. ”

"Really, really? I'm so happy! Our Qing Dynasty is still very short of salt, if you can only test that you can use seawater to dry fine salt, there is no seaweed or iodine, it is also a major contribution to our Qing Dynasty. Let our Daqing not cause so many disputes over salt, and you will make another great contribution to Daqing. ”

"I remember that the Empress Dowager also asked about exotic salt, and asked the minister if he had a formula, but the minister was really ashamed, and he couldn't understand what he said, how dare he say it casually."

Kangxi immediately understood what the prince meant. If Huang Ma Mo issued a decree to let the imperial uncle immediately use sea water to dry salt, they would be guilty of bullying the king if they couldn't dry it. Moreover, at that time, Huang Ma Mo and his father were at the tip of the needle, and the emperor's uncle obeyed Huang Ma Mo's edict and couldn't show it, so the contradiction between his father and Huang Ma Mo would be deeper. It seems that Uncle Huang is really a very wise person, and the skills that people have learned are a contribution to the Qing Dynasty, and it is understandable not to take them, who wants to find a flail for himself? He said: "Don't be a burden on this matter, I asked my little aunt and Uncle Tian, it's okay, if it doesn't work, let's still use the old way." ”

"Thank you for the emperor's compassion." The prince didn't say that the queen mother asked them to dry salt in an ordered tone. At that time, the Empress Dowager still had some power, and if she couldn't dry the salt, she could have convicted herself of "bullying the king", because she was very jealous of herself at that time, for fear of robbing her son's dragon chair. The current situation is very different, first of all, the power of the empress dowager is basically in the hands of her grandson, and she has the edict of the emperor in her hand, but she doesn't want to be the emperor, which is also a great deterrent to her. Why is she so polite to the two mansions, she is afraid that she will have to return to the dragon chair at any time. You said you didn't have that mind, did she believe it?

The method of drying salt in seawater is indeed in Yun'er's hands, and it is not too complicated. It is a bit troublesome to turn coarse salt into fine salt, and it must be filtered with activated carbon, otherwise the impurities such as sodium ions, chloride ions, and magnesium ions will still remain in the coarse salt solution. There are still many disadvantages to the human body when eaten.

The emperor was not embarrassed to ask the prince again, people send millions of taels of silver to the treasury every year, and they have to chase after the method of drying salt, which is as unreasonable as peeling two skins off a cow.

Fortunately, Xiaoli cast a net all over the sky, and she thought that she could make money, so she downloaded it and pressed it on the paper. Then give it a try! This kind of thing must be Tian Liang taking the lead. Don't look at him now as the Duke of Dingguo, the Grandpa of the Kingdom is also a relative of the emperor, the uncle of the emperor today. But many things have to be done by him, and no one can play without his guidance.

The prince told Yun'er what the emperor meant, and Yun'er carried the information on seawater and salt from an underground secret room that night. Tian Liang got the printing materials in his hands and went home to study the implementation plan for several days. Then he said to the prince: "In the past, salt drying in seawater was to choose flat seaside tidal flats in areas with mild climate and sufficient sunshine to build salt pans. The exotic salt pans are also flat seaside tidal flats, divided into two parts: evaporation ponds and crystallization ponds. First, the seawater is introduced into the evaporation pond, the water is evaporated by the sun, and then poured into the crystallization pool to a certain extent, and the seawater will become a saturated solution of salt, and then the salt will be precipitated by the sun, and the crystals obtained are our common coarse salt. The remaining liquid is called the mother liquor, from which multiple chemical feedstocks can be extracted. Barium chloride, sodium hydroxide, and sodium carbonate are added to the coarse salt in turn, filtered with activated carbon to obtain precipitation and filtrate, and then dilute hydrochloric acid solution is added, and the evaporation crystallization obtained is the pure salt sodium chloride. This process is cumbersome. Fortunately, we have this preparation in a foreign land, and we have bought a large amount of activated carbon and a small amount of barium chloride, which is enough for 20 years, so it is certain that seawater salt drying is successful. At that time, we should also leave, and what the emperor will do is not our business. However, the method of making activated carbon is not very difficult. ”

"Then let's start acting, we are only responsible for doing experiments, and if we succeed, we will hand over the method to the emperor, and let him solve the future by himself." You can't rely on us for everything. ”

After reading the information, remembering the proportions of various added materials, and preparing other tools and instruments for drying salt, Tian Liang and Wang Ye rushed to Tianjin with a full set of people such as twenty personal soldiers, ten guards, cooks who cooked, and watchmen. Approach the local prefect's yamen and ask them to carve out a flat, sunny tidal flat. Recruit local bricklayers to do the work.

Prince Rui and Duke Dingguo went to the prefect's yamen in person, which was a great honor.

The prefect heard that the prince of Rui had come to build the salt pans, which was a major event in the Qing Dynasty, so without saying a word, he transferred 200 strong men from the local area to help the prince.

The ground was quickly taken care of, and the small embankment of the square salt pond that held back the sea water was erected, and the drying of salt began. Don't look at the people who are basically rude, it doesn't mean that they don't understand anything, Tian Liang told them that the prince was here to experiment with seawater salt, and these people knelt down for the prince and kowtowed respectfully three times. The prince brought them rice bowls, because the construction of a large salt pond shows the courage of the prince, how can people who don't want to do business be willing to invest so much? Salt is a necessary thing in people's lives, salt must be eaten every day, and people who can eat cannot do without salt, not a dispensable thing.

When the first batch of white fine salt was packed into small bags of salt, the people were so excited that they shed tears: in the past, salt was refined by boiling salt, and what came out was coarse salt, which was yellow and had a bitter taste. What are the conditions of the Qing Dynasty, such as activated carbon? Now we can produce such white salt.

The prince asked Tian Liang to tell Emperor Kangxi the whole process of drying salt, and then he handed over the great cause of drying salt to someone he trusted in the future, and then retreated. There is a lot of business in the house, and there is really no time to run this, and Emperor Kangxi was stunned. Such a big skill is given to yourself? Tian Liang smiled and said: "We brought back the method, and also brought back a certain amount of activated carbon and barium chloride, etc., because the money in our hands is counted, and there are not many things to buy. Activated carbon can also be produced by itself, and there is no other way to do it. Information about activated carbon, Wechen will hand it over to you when you find it. If you want to thank a girl named Jory. She printed this message out to your aunt from an exotic website, and the two of them were friends. ”

"How can I express my gratitude in person? How will this girl be rewarded? ”

"You can't do this, and Weichen can't do it either, because it's too far. Just remember her name, and don't forget her contribution to the Qing Kingdom. She is a very ordinary rural girl. He is very tenacious and tenacious, and he came to the capital from the countryside more than 2,000 miles away, not only to take care of the housework for his cousin's family, but also to help his aunt's business, to study university courses on his own, and to take your little aunt to the street to buy things. By the way, I forgot to tell you that 2,000 catties of seawater can produce 60 catties of salt. ”

The prince knew that the Qing Dynasty was very short of salt, and once he did the business of drying salt, he would be inseparable from right and wrong, and the business in the house would not expand to infinity. The method of drying salt in seawater was handed over to the emperor, and the emperor would hand over the future salt works to the Ministry of Internal Affairs for management. At the same time, the prince also handed over all the activated carbon and barium chloride to the emperor, he didn't want to be involved in the salt farm. There are still mountains of goods to sell!

Kangxi didn't know how to thank the emperor's uncle. It seems like a method, a recipe, if he doesn't give it to you, there is no way. This is a method that can not only solve the shortage of salt in the Qing Dynasty, but also solve many of the shortcomings of salt in the past. At the same time, he also understood why Uncle Huang didn't hand over the formula back then. It's people who can't do without their heads! At the same time, Kangxi also guessed that his grandmother might be jealous of the imperial uncle because of Taizong's remark that the emperor's uncle was the prince, and even wanted to find some way to eradicate him. Uncle Huang is too wise and knows what the right time is. Unloading the mill and killing the donkey is the method adopted by many rulers, and the method adopted by those who have achieved high merit. But to use this method on the emperor's uncle is to lose his conscience.
