But it is also a fact that after the establishment of the school, the imperial court subsidized a lot, including the salaries of several gentlemen, and the salaries of only six people reached more than 1,000 yuan a year, among which Song Jiu was the highest, and the monthly money, grain and rice were almost close to 30 yuan.

There are also rewards from time to time, pen, ink, paper, inkstone, all kinds of books, tables and chairs, and so on.

This is a subsidy placed in the open place, and there are all kinds of dark places, such as the cost of this dinner, the cost of copying the examination papers, and the chalk on the blackboard, all of which are small money, but these small coins are not small money when they are counted together. These were all paid by Song Jiu out of his own pocket. There was no accounting, and the salary given to him by the imperial court was far from enough.

Students are not stupid, they all know it in their hearts.

Zhu Sanniang pinched Zhu Sanyi in disgust, Song Jiu didn't take it seriously, the two have often joked together since the year before the fight, and they are used to it.

The seventh sister was still reading: "More than 10,000 catties." ”

"Seventh sister, don't read it, the yield is also high."

"Song Jiu, why are they growing so well?"

"Dr. Yan, there are many reasons, three fertilizers have been applied, and there is a lot of farm fertilizer, which is not affected by rain, the temperature is constant, and carbon dioxide, yes, you still don't have to ask about this." Song Jiu didn't want to say more, and said that Dr. Yan couldn't understand it, let alone understand terms such as photosynthesis.

"How much will it produce?"

"I don't know, but I don't think it will exceed 80,000 catties."

"Eighty thousand catties." Scared together.

Song Jiu shook his head, part of it was a test factor, and some of it was also infected with insect pests, or it was not well protected, which affected the yield. But the main thing is the seeds, and it cannot be said that the fertilizer is bad. The fertilizer is bought with their own money, and all kinds of fermented manure. plant ash, and wheat bran. There are also three fertile soils, nitrogen, phosphorus, potassium and various trace elements are enough. It can't be said to be the temperature, ice and boiling water are used to compare the body temperature of a person, and a thermometer is made from zero to 100 degrees, although this thermometer is very strange, basically very accurate, and the temperature is always adjusted between 25 and 20 degrees by charcoal fire. It can't be said that it is water, and the more than 20 vegetable farmers who take care of it have grown vegetables all their lives. All of them are connoisseurs. There's only one reason for that, and that's seeds!

In my previous life, I heard that cucumbers in greenhouses can yield 30,000 catties highly, and one Song Jin was also measured by calculating the density of water, and one Kaifeng Song Jin was 589 grams. About Kaifeng, this Song Jin is not standard, and it is more than 590 grams in memory. Anyway, the mistake is almost the same, close to the one catty and two taels of the later generations.

But it's also 25,000 Song Jin.

In fact, no, the yield of leeks and celery is a little lower, and Song Jiu estimated it evenly, and it can only be around four thousand Song catties. It's not that I imagined that there would be 10,000 catties of vegetables per mu.

However, this number frightened everyone.

I can't explain this. Song Jiu simply didn't talk about it, and said: "It's high yield, I'll calculate another account, the cost of Liuli." The cost of the greenhouse itself, the cost of coal, and the cost of usual management. Like this snowy day, in order to keep out the cold. It is necessary to add wheat straw mulch, and add a large amount of wheat bran and distiller's grains to improve cold resistance. Frost and snow should be cleared every day, and even some coal stoves should be built in the corners to prevent the cold air from entering the corners and freezing vegetables. How much will this cost? More than 20 vegetable households pounced on it, and Hu Xingtou took more than a dozen villagers to patrol. This cost alone will reach more than 7,000 yuan. I can't calculate my income at the market price, I can only calculate my income at the price of the shed, and the average price of a pound of vegetables is only 400 tens of yuan. I'll still earn. However, how much does it cost to spend various tests? In addition, larger classrooms will be built next year. How much money will be left by this time next year? ”

"Yes, it's too costly," Dr. Zhang couldn't help but sigh as he heard Song Jiu finish settling the accounts.

"Dr. Zhang, I can't say that, the main cost is glaze, which is not a good solution to the high cost caused by mass production. Once mass production is realized, the cost of one acre of glazed land will drop to 80, 50, and 20. ”

"So many glasses and twenty times?"

Song Jiu scratched his head and said that he had leaked his mouth, twenty guan was about impossible, the cost factor was determined, like sulfur, the imperial court followed his own advice and borrowed three sea ships from Wu Yue, the Song Dynasty did not have decent sea ships, let alone sea charts, and more than 5,000 stone of sulfur were transported back this year. Otherwise, there will not be enough sulfur. Sulphur was worthless on the Ryugu side, but the cost of sea vessels was too high, and it was a sailing ship that had to be reached by the use of the monsoon. There are also risks at sea. From Ryu to the capital, the mud was also moved to the gold price. As well as some special sand required, as well as other materials, the mining cost is not counted, and the freight to the capital is also high. If it weren't for his own proposal, the imperial court would have restrained the price of coal, and the cost would have been higher. Therefore, Song Jiu said: "Twenty yuan is about impossible, but forty or fifty yuan is still possible, after a few years, the seeds will gradually improve in the greenhouse, the yield will be further improved, the vegetable farmers grow their own, the labor money is saved, the greenhouse can also be built by itself, and the fertilizer is diligent and does not need money at all." It is to buy some coal money, and some three-fertilizer soil money. Then the cost of one acre of land is enough for a hundred yuan, and it is not even used. The cost of a pound of vegetables will drop to twenty or thirty yuan, and you still have to make money by selling it for forty or fifty yuan. At that time, out-of-season vegetables can enter thousands of households. ”

Everyone nodded their heads together.

This vegetable is not eaten by people, at least not by the middle and lower class people, if it is forty or fifty dollars a catty, it is still expensive, but ordinary people can afford it if they want to have an appetite.

In fact, it is still the output, if it is increased to 10,000 catties, the market price may be able to drop below 20 yuan, which is unlikely. And once promoted, there will be all kinds of pests and plagues, after Song Jiu took the land, he immediately plowed and exposed to the sun, or some insect pests occurred, if this happened, Song Jiu had no way to stop it. Once the small and medium-sized vegetable farmers operate, they will inevitably be careful in their calculations, unlike Song Jiu's lack of money to buy, this careful budgeting has a benefit, saving costs, but if it is not done well, there will be mistakes, which will eventually affect the harvest. In practice, forty or fifty wen a pound of out-of-season vegetables will be far away, and the most realistic thing is that it will drop to about 100 wen.

The next day snow stays.

Song Jiu went to Hezhou first, but Hezhou stopped working, leaving only some victims and soldiers to guard and patrol. Song Jiu went to see the victims first. In fact, the victims spent more money, and it seems that the wages are less. Subsidies for clothing, food, cloth, coal, sheds, salt, vegetables, etc., are spent more than the wages of the people of the two rivers. I don't care about that. He should do good deeds, but he is afraid of accidents for the victims.

The scene seen is not evil, many victims are cleaning the snow on the shed, and there is a coal stove in the shed, although it cannot be said to be warm, it is not too cold, Song Jiuyi Village walked by, and told them to open the door from time to time to ventilate, otherwise they will be poisoned by coal. With the horseback galloping to the steel prison.

A few days later, Song Jiu went to Kaifeng Mansion with a few things.

Meet Zhao Kuangyi. First, he took out a thing, an iron shaft, and two bearings. This Zhao Kuangyi has also seen it on Hezhou, but this bearing is different, and there are ten steel columns outside. Zhao Kuangyi said: "Song Jiu, what is the purpose of this thing. ”

Song Jiu took out two more wheels from the outside and threw them to rotate.

"That's good......" Zhao Kuangyi's eyes lit up.

Song Jiu has said many times that the cost of transportation in this era has hindered the development of many things, including the cost of colored glass. As long as there is this dynamic cost, its price can never be cheaper. But there's no good way to do it. Speaking of steam trains, that's a joke, steam engines are not complicated. If more than ten years later, a large group of students who are proficient in physical science have grown up, and steel production has surged. The quality of steel can be made if it keeps up. But getting on the steam engine on the train is not easy. Besides, there are so many irons to lay the rails? No more, just lay a railway from Kaifeng to Chang'an. That is of great significance, and the cost of dealing with the Tanguts will be reduced by half in the future. Even if the Jin people invade the Central Plains, they can immediately shrink to the defense of Guanzhong. But is it possible?

These Song Jiu don't think about it at all, and it's a fantasy, even if it's the railway from Sanmenxia to Chang'an. Song Jiu thought about it, but he still thought of ideas on the basis of the original.

Now the transportation is a ship and the other is a car, and the cost of the ship is still acceptable. It's not that the car is bad, some big cars can also pull more than 1,000 catties. But this clumsy wooden wheel has two drawbacks, one is the friction is large, and the other is the serious loss, especially the axle. Although some parts are replaced with iron or ceramic, the damage rate is still serious and it also affects its speed.

It is achievable for a person to march 100 miles a day, but it is very dependent on logistics supplies, so the army can often only march 30 or 40 miles or 20 or 30 miles a day. The speed of private transportation is also not fast.

So Song Jiu improved the axle and directly used the bearing.

The bearings do not look complicated, the inner steel hoop and the outer steel hoop, plus steel balls, asphalt and grease can replace the lubricating oil. The upper outer hoop can be made tighter by thermal expansion and cold contraction.

But there is a lot of trouble, this is not like those bearings on the crane, they are very large, and the problem of half a millimeter error is not too serious. Reduced to the carriage, the outer hoop and the steel ball cannot be wrong by 0.1 millimeter, and the steel ball itself cannot be wrong by 0.1 millimeter.

And the throwing technique of steel balls is also a problem.

In the past, the bearing on the crane was solved by the mold plus manual mode, the waste rate was serious, and the mold was almost disposable. If it is scaled down to be more accurate, it will have to invest in further research and development. Otherwise, it will be manufactured, and the price will be unacceptably expensive.

"How much will it cost to develop it?"

"The two kings, Weichen don't know the way, but if you want to develop it, the court must reward it, and under the heavy reward, there must be a good plan. When one good strategy after another, you can succeed. Its significance is not trivial. ”

"This official is not a fool, can't he see it." Zhao Kuangyi walked back and forth a few steps, this is the benefit of Hezhou development, if there is no Hezhou, there will be no such bearing, think about it and laugh, and said: "Song Jiu, can it be developed, how much will it cost at most?" ”

"The second king, Weichen has built many bearings in the steel supervisor, and he is no stranger to its craftsmen. Weichen thought that it was impossible to reduce its cost to three or four times that of ordinary steel products, but if it was reduced to about ten times that of ordinary steel products, craftsmen would definitely have a way. More than ten times more expensive, but it does not use a large amount of steel, and the price is acceptable. As for how much silk, Weichen didn't dare to say, but he could allocate some money in the steel supervisor to support craftsmen to develop and ponder in their spare time. In this way, there will not be much money, even if it is added to the reward. Brainstorm ideas, and eventually there will be ways to bring costs down. Wechen has a lot of affairs, and it is far away from the steel prison, otherwise Wechen can also take care of it. But if the court is interested, Weichen can ride over from time to time to take a look, and come up with ideas by the way. ”

Zhao Kuangyi rolled the wheel with his foot and said, "As long as the fee can be afforded, the official can call the shots, but Song Jiu, you forgot one thing." ”

"What's the matter?"

"It's time to go."

"Really let Weichen go to Liangchuan."

"You don't have any jokes, is the imperial brother joking with you?"

"There is no need for Weichen on either side of Liangchuan, and it is useless for Weichen to go," Song Jiu said bitterly. Han Chongyun told the inside story, Liangchuan is not a problem of displaced people, get Wang Quanbin back, replace him with Cao Bin, and then go down a few good officials to appease people's hearts, and the displaced people themselves can take the initiative to return to their homes. The problem is that the Song Dynasty has grown up in Liangchuan this time, and if there is a slight carelessness in the governance in the future, it will poke the hornet's nest. It doesn't have to be Zhang Shun and Li Xiaobo, Wang Shun and Zhang Xiaobo can also be, as long as the officials are not good and one person takes the lead, the people are likely to rise up.

"Let's take a look, Lu Xianggong mentioned it twice in the memoir, let you go west to take a look, don't worry, the Liangchuan rebellion has not been settled, and the imperial court will also send capable soldiers to protect your safety." You are very expensive from the bottom to the bottom, and even a hair that falls out is steel, expensive cucumbers and eggplants, glass, buns that are always money, and a lot of copper smells......"

"Second king, stop, stop, don't say it, do I promise to go west?" (To be continued......)
