Kong Minxing said: "I don't care much about anything else, it's that this corn and sweet potatoes have been promoted, and there are already people from southern Jinnan who have come to find seeds to plant back, but our influence can't reach southern Jinnan and southern Shaanxi, otherwise, these two crops are planted everywhere, regardless of its dry weather and drought, the people can fill their bellies, this person, as long as they can eat enough, they won't make a fuss, and the world can be peaceful......"

Zhang Han's heart moved, and he looked at Kong Minxing, who had a dark complexion...... In recent years, this old man has been engaged in the matter of acres in the area of Lizhuang, from the accumulation of manure and ridges to the introduction of water into the field, to the selection and breeding, and has made great contributions to the increase in the income of the acres in the area of Lizhuang, and then it is to plant cotton in the grassland, of course, it is also a large area of corn and sweet potatoes, and for several years in a row to breed good varieties and study ways to increase yields, corn and sweet potatoes, these two foreign crops have been initially tricked, and the average yield per mu has increased from dozens of catties to a stable of more than 100 catties, and then the average yield per mu is close to two stones. The high-yield sweet potato field has exceeded the yield of Sishi per mu...... This is not easy, from the middle and late Ming Dynasty South American crops into China, to really in northern China on a large area to promote planting and increase production, but after nearly a hundred years, the so-called Kangqian prosperous era, is nothing more than foreign drought-tolerant crops have come in for a long time, a large area of planting, to solve the most basic problem of food and clothing, and that's it. Pen ~ fun ~ pavilion www.biquge.info

According to the control area and population distribution of Heyusheng, in the eyes of many people, they don't have to care about the promotion of these drought-tolerant crops, but Zhang Han's attitude has always been that the grain is only too little, not too much, and it is better to expand the area of grain harvest everywhere with his hard work.

"In the next step, I will go to the grassland and plan more corn fields and sweet potato fields, as well as potatoes, tomatoes, peanuts and other things, which can also be slowly promoted." Kong Minxing said with a smile: "There is one thing, I don't teach people to breed tobacco, the military department has enough smoking guns, and I am really fed up with the sin." ”

Zhang Han and Sun Jingting both laughed, there are indeed more and more high-level smokers in the military department, of course, there are more and more smokers in the whole of North China, the north is very cold, and the winter is commonly known as the cat winter, in addition to playing money, it is to avoid the cold in the room, and tobacco quickly became popular in the north as soon as it appeared, just like the chili pepper quickly became popular in Yunnan, Sichuan, Guizhou and other cold wetland areas.

Sun Jingting laughed a few times, glanced into the room, and said solemnly: "Okay, it's ready, you can start." ”

Zhang Han rubbed his hands and said, "I made such a special trip, don't let me down." ”

Everyone was solemn, and everyone knew that the prototype tested today was really related to the income of millions of taels of silver in the next few years...... If you succeed in grabbing the market of the entire North China, as well as a large area of the Western Regions, all the Mongolians are the market that can be grabbed in the future, and not everyone in the North is wearing leather jackets, and the cotton cloth with low price and good quality is as popular, and even the Russian trade representative who stayed in Lizhuang also said that the Russians also need low-cost and high-quality cotton cloth, and the cotton textile industry in Europe is still quite backward in this era, and the sheep cannibal movement in Britain is the rise of the wool textile industry, in order to monopolize a large amount of land for sheep spinning, The big farmers did not hesitate to drive out the peasants and tenant farmers, and turned the fields into pastures for grazing sheep.

At this time, the cotton cloth of the Ming Dynasty was also traded abroad, but it was mainly for the Nanyang and Japanese markets, and the main export was raw silk and finished silk, the reason was also very simple, the price of cotton cloth was too low after all, and the profit could not be compared with raw silk and silk and porcelain.

However, it is not a big problem for the Russians, in addition to trade, they can use it for their own use, which means that in addition to the domestic market, there is also a considerable foreign trade market where they can make profits.

Chang Jin and Song Yingxing, Song Yingsheng brothers, as well as the heads of the various bureaus are in the house near the river, the machine is directly placed in the house, and there is a stream of water flowing in the house, before the finalized production, the military department has maintained the highest secret level for the production of the prototype, and the personnel in and out must be registered and verified, and no one is allowed to disclose the test and finalization process of the prototype.

"I've seen adults."

As soon as Zhang Han entered the house, everyone hugged their fists and bowed, only Chang Jin still had the usual embarrassed face, of course it was wrong to worship, and it was awkward not to worship.

"I've seen my father-in-law." Zhang Han arched his hand to Chang Jinyou first, and then waved his hand to everyone and said, "There is no need to make so many false articles, let's start quickly." ”

"Yes, this begins."

Song Yingxing agreed, and his expression couldn't help but be a little nervous.

Of course, the institute has tried many times before, and the success rate is quite high, but no one can guarantee the success of the second time, and like all handmade products of this era, it is likely that the entire machine will be scrapped because of a small flaw.

Even if this machine is made by Wang Debang Yang He, the handmade products are unique, but in terms of stability, they are certainly not as stable as the machine to maintain a fairly high stability.

In the eyes of everyone, a group of research institute staff pushed the machine that was half a person high to the water's edge, Zhang Han stepped forward to observe, the machine is mainly made of iron, there are also quite wooden components, three spindles hang low in the lower half of the machine, the spinning thread has been wound, the end that drives the power of the machine is connected with the square machine itself, after the screw and the part that drives the water power sink into the water, everyone looks at it with bated breath, except for the sound of running water in the whole room, Not a bit of the rest of the sound could be heard.

"It's moving, it's moving." Kong Minxing is a layman in the machine, although he has read some books, his main energy has always been used in agronomy, so as soon as he saw the machine drive, he immediately shouted.

None of the others made a sound...... Hydraulic drive is only the first step, the second step is to rotate the screw, and the large and small gears are also rotated, but at this time it is still only the second step, and then people see that after the gear turns, the three spindles also rotate, and the yarn begins to twitch evenly under the rotation of the spindle, spinning the lint into a solid and fine yarn.

"It's done!" Zhang Han's face flushed, and he was the first to shout with a fist.

"It's really done!" Sun Jingting was also excited, although he had been in Lizhuang recently, although he had come over every day to see, but the excitement at this time was still beyond words.

All of them were the same, and there were a few posteriors of the institute who shed tears.

Chang Jinyou was also excited, he said: "The clock has not produced results, and this time it can really explain to the people up and down." ”

The pressure of Changjin is not only from itself, the miniaturization process of the watch institute is not very smooth, but every day there are new grandfather clocks produced, still bring considerable profits to the military department, although the expenditure is still greater than the income, but with more and more skilled craftsmen, the number of grandfather clocks that can be produced will also increase significantly, when the output increases, even if the cost of research and training craftsmen is still very high, the profit will still be much greater than the cost, but it takes time.

The pressure of the Chang family comes from Chang Wei, and many people have talked about it, the Chang family is like a relative interfering in politics, Chang Wei has squandered it in Taiwan by virtue of Zhang Han's cousin, and now most of the proceeds of the iron trade have been wasted by this kid, if it weren't for the nearly two million taels of silver invested in Taiwan in recent years, why would the military secretary be so sad this year!

Of course, the Chang family doesn't care about these rumors and discussions, but Chang Jin can't help but have a little idea in his heart, if the research project led by the clock and watch brings extremely rich profits to the military department, it will save someone from chewing their tongues behind their backs, saying that the Chang family is a drag on the Zhang family.

Zhang Han glanced at his father-in-law, in fact, he was in his forties, and his sideburns already had obvious gray hair, and it seemed that the pressure on Chang Jin in the past two years was really not small.

"It's time to mass-produce prototypes." Zhang Han said: "The transportation and preservation of lint must be done well, and this matter is left to the soldiers." Then after the success of weaving cloth in the Beijing area began to slowly distribute goods, this year's output will not be very high, up to 300,000 horses, with the average price of Beijing cloth about one or two or five dollars to calculate, remove the cost of this year in the cloth can earn more than 400,000 yuan, is not without a small supplement. ”

Everyone was excited, they worked so hard to make a prototype, so why did they come?

I have to admit that after a long period of deliberate operation, the cohesion of this group is already amazingly high, and when people are rushing to work, they will certainly calculate what kind of reward the military secretary will give this time, but more thoughts are also about helping He Yusheng to tide over the current difficulties.

Zhang Han gave everyone a stage where they could give full play to their strengths, and tried to eliminate a lot of bad influences, not only giving them quite good living conditions, but also giving them a considerable sense of respect and identity.

At least within the control of He Yusheng, the respect for craftsmen and technicians is something that these people can't get elsewhere in Daming.

In the eyes of the scholars, these craftsmen who can make a lot of unbelievable and unbelievable items are actually similar to the likes of prostitutes, but they are just idle and playing to relieve boredom.

In Lizhuang, none of this is a problem......

Sometimes people not only lack money, but also need the respect and recognition of society, and Zhang Han knows that this is also important.

Song Yingsheng arched his hand and said: "As long as it can help the military department, we will not work hard in vain." ”

Yang Hegao said: "We will mass produce as soon as possible, first select a site by the canal, build a platform, and then install the machine one after another. ”

Sun Jingting said: "The next step is to train spinning workers, according to our calculations, a qualified worker can see three to five machines, we take three machines per person, need two people, each person works for six hours a day, two people work in shifts, the machine water flow does not stop, personnel do not stop, be sure to spin the lint in the shortest possible time." ”
