After inspecting the chicken coop, Yang Bo looked at the pig farm and cattle farm with great interest, these old farmers have experience in raising livestock, Yang Bo could not mention anything to improve, so he told them to clean more to reduce the occurrence of epidemics, because the most tense cultivation season has passed, on the way to the brick kiln, Yang Bo pondered, should we send a large number of technicians to the forts to teach the tun households to master some new breeding techniques, the question is, where do a large number of technicians come from?

The brick kilns were set up on the riverside outside the farm, and because there were enough bricks to fire, the three domed kilns were abandoned, and some of the fired adobe bricks were still left inside, many of the dried mud embryos had dried up and cracked, and large piles of soil were discarded here.

Zhang Fengjin of the Tun Affairs Department didn't know why Yang Bo was so interested in burning bricks, so he immediately introduced: "My lord, the villain was originally from the Construction Division, and these bricks were fired by our company.......

Yang Bo took a handful of soil, grabbed it in his hand and pinched it, and continued to listen to Zhang Fengjin's introduction

“…… It is necessary to break these raw soils, sieve off large stones and dry them, grind them into powder, add water and mix them thoroughly, roll them with instruments, and make them into brick embryos after repeating them many times, and dry them in a cool place for more than ten days, and then enter the kiln to fire, but the task was urgent at that time, so the raw soil selected was not too clean, and the fired bricks were easy to crack."

Zhang Fengjin said while taking a brick and handing it over, but he didn't expect Yang Bo to take it at all, Zhang Fengjin was extremely embarrassed, his hand stopped in mid-air and he didn't know whether to retract it or continue to hand it over.

"Adults are thinking about things. You don't have to mind" Xiao Wu came out in time to solve the siege, Zhang Fengjin looked at Yang Bo and saw that his brows were furrowed. I don't know what I'm thinking.

The reason why Yang Bo is interested in brick kilns is that he wants to observe the firing process of bricks and tiles to see if he can be inspired by another extremely important thing, that is, cement, cement is the foundation of all buildings, with cement, the construction of tunpu in Lushun alone can save countless glutinous rice every year, and at present, only more than 100 tunpu have been built on the Jinzhou Isthmus. Every tunpu was overstaffed because of the lack of financial resources and the serious cost of food, and Yang Bo really couldn't afford these expenses. The Isthmus of Jinzhou is very large, and if there is no Tunpu, it will not be able to accept more displaced people, and without more displaced people, it will not be able to obtain an overwhelming advantage over Houjin, so to speak. Cement. It is really a very important strategic material.

It took a long time for Yang Bo to come back to his senses, looking at the eyes of the cave looking at him, Yang Bo smiled and turned his head to Zhang Fengjin and said, "What do you use to burn the kiln?" ”

Zhang Fengjin hurriedly replied: "They all use charcoal, there are a lot of trees around here."

Yang Bo grabbed another handful of clay and ordered: "You record it, I have some ideas, you can help me experiment and see"

Zhang Fengjin ran to the door of the cave and shouted outside: "Xiaomei, hurry up and come in to record"

A few unrelated people went out of the cave, and a girl walked in. She had been isolated from the periphery just now, and she had no chance to squeeze in.

Yang Bo's gaze stayed on the girl's face for a few seconds. Turning around, he asked Zhang Fengjin: "You can't write?" ”

Zhang Fengjin's face was flushed, his hands didn't know where to put it, he swallowed and said: "Back to the adult, the villain has never read, he has been working for people since he was a child, and he learned the craft of burning bricks and tiles, and then followed the adult, but he didn't expect to be favored by Lord Han, and he chose the small one to be the director of the construction department, and the whole family didn't have to worry about drinking the old snacks, but the villain was old, and he went to a private school for tutoring a few times, and his brain was not bright, and he couldn't learn anything famous, so it was delayed......"

Yang Bo nodded and advised: "Live to be old, learn to be old, I still have a lot of things to do for you in the future, how can I do it if I don't know words?" ”

Seeing Zhang Fengjin patting his chest and swearing, Yang Bo didn't force him, and turned his head to look at the girl.

"Student Han Fangmei, I've seen the teacher" Han Fangmei squatted slightly at Yang Bo with the etiquette of a private school, and was blessed.

Yang Bo nodded helplessly, although he repeatedly instructed that after graduation, he was not allowed to use teachers and students to commensurate, but most of the students still couldn't change, and then Yang Bo was too lazy to be long-winded, you can call it whatever you like, and asked casually at the moment: "Which issue?" ”

"In the fourth phase, the teacher has taught the students a few times, and the teacher has asked the question of why the flowers have various colors, and no one in our fourth phase can answer them...... "The students from the private school are not like others who dare not breathe when they see Yang Bo's atmosphere, Han Fangmei is not arrogant or humble when she speaks, but it is a bit like a question and answer with Yang Bo's class, and many people around who have not been to a private school are secretly surprised.

Yang Bo smiled slightly, and then waved his hand again: "Record, one clay and one plant ash are fired, one clay is added to ten parts of plant ash, the clay should be selected as the finest sieve, one clay and one sand, the sand will be the finest, preferably white sand, can you start work tonight?" ”

Han Fangmei shook her head and said, "Teacher, before firing the kiln, you still have to warm the kiln and burn charcoal, and it will take two days to prepare." ”

Yang Bo was a little disappointed, and said, "Then let's prepare first, it just so happens that I also have time to think about it, what should I add to this clay?" ”

The people around were all looking at each other, and when Han Fangmei saw Yang Bo walking around with his hands behind his back, she boldly asked, "What does the teacher want to burn?" Is it brick or ceramic, or glass? Burning sand with this kind of earthen kiln and charcoal cannot be burned, and the temperature is not enough. ”

Yang Bo reacted, adding sand to the clay is obviously wrong, that is the process of firing glass, not to mention that there is no blast furnace, the main component of sand is silica, and the temperature is required to be at least 1,000 degrees or more......

Seeing his students looking at him with curiosity, Yang Bo said patiently: "I want to burn a kind of adhesive, simply put, it is like the kind of plaster plastered between the stones when we built the fort, which is better and stronger than the plaster. ”

Zhang Fengjin hurriedly replied: "My lord, the plaster is generally stirred with loess, lime, and clay with water, but this kind of plaster is only used on the general earthen house, and the plaster used in Tunpu does not add water, but adds glutinous rice juice and mixes it in the gaps." Add glutinous rice juice to be firm. ”

Yang Bo thought for a while: "Then use the clay soaked in glutinous rice juice and add lime, or loess and clay and lime, and you will give me a test for each recipe." If it really doesn't work, just start the blast furnace, I transferred a few glass workshop masters from Lushun to refer to it together, in short, this new type of plaster must be made. ”

Everyone in the Tun Affairs Division nodded yes, and Zhang Fengjin looked at Han Fangmei's figure, and secretly made up his mind in his heart. The adults seem to have a good sense of her, and they need to find an opportunity to promote her......

Hearing Yang Bo's order to stay on the farm for a few days, Qiu Guang, the personal guard in charge of the guards and the commander of the third battalion, was scared to death. This farm is located in the wilderness, and the ability to protect itself is poor, although it is unlikely that the Tatar cavalry will penetrate here, but the experience of the criminal camp cannot be ignored. There was only one company of troops in Guashan Fort. In desperation, Xiaowu asked Yang Bo to urgently transfer two companies stationed in the Lushun Youth Model Battalion to serve as guards on the farm, and Tie Niu, who learned the news, was not at ease, so he transferred two companies of the Wu Zhong Village Department of the second battalion to be stationed in the area of the seaside pier more than 30 miles west of the farm.

The next day, the Department of Assistance for the Displaced People, the Department of Finance, received the order. The new technology R&D team and other relevant personnel affiliated with the R&D department rushed to the farm, and Xiao Changgui from the management department of the private school in the three places also came with the students of Lushun Phase 5. The whole farm was overcrowded, and the lawless students made the farm like chickens, dogs, and cats on the wall......

No one knows how much impact Yang Bo's unintentional move had on the empire in May of the seventh year of Chongzhen, and later a total of eight ministers from the Ministry of Industry, Agriculture, Science and Technology, Communications, R&D, and Commerce attended this gathering, and there were many experts who became top scholars in various industries......

Yang Bo insisted that copying one or two high-tech to the Ming Dynasty could not finally reinvent the country, the need for a large area, persistent science popularization, for the students of private schools, Yang Bo believes that it is more important to let them maintain their imagination than to pour knowledge into the dead, so he takes more of an enlightening way to teach, and of course he will not let go of this opportunity to practice.

So Yang Bo has been taking these students to work in the fields for the past few days and asking them questions

"I think Lushun is by the sea, and the temperature difference here at night is too large due to the sea breeze, so it causes the slow growth of these temperature-loving crops, how do you think to solve this problem?" Yang Bo asked.

"Teacher, what is a temperature-loving crop?" These students also work in the fields on weekdays, but this is the first time they have seen these high-yield crops.

Yang Bo patiently explained: "Crops and people are almost the same, different crops have different environmental requirements, they can't grow normally if they don't meet certain conditions, like this sweet potato, it likes to grow at a temperature of more than 20 degrees, here the temperature is enough during the day, but it drops sharply at night, so we now see these sweet potato seedlings withered yellow, falling off, thin and small, we have to find a way to keep the temperature in the field at about the same during the day, understand?" ”

"Add a fire?" One student had the audacity to suggest.

Yang Bo nodded and said: "Yes, it's like we sleep at night, what if it's too cold, add a fire, the method is good, direct and effective, but it's not realistic, we will plant sweet potatoes in a large area in the future, besides, do we have to make a fire for the field every day to keep warm, how much firewood do we have to burn?" ”

Many people laughed, including those from the various divisions gathered outside, and one student suggested, "Teacher, why don't we heat up the soil and pile it on the edge of the field, so that we can maintain the temperature."

Yang Bo encouraged: "Yes, your method is also very effective, but the shortcomings are as obvious as burning a fire, it consumes too much manpower and material resources, we can jump into the fire This method, how about other methods?" ”

Another student dragging his nose said, "Teacher, let's cover it with a quilt."

Yang Bo was immediately overjoyed, stepped forward and touched his head, and said with a smile: "Very good, your method is good, but this is a field, how to cover the quilt?" ”

The student didn't know how to answer, Yang Bo suddenly got up and said to Ma Xinyi at the high-yield crop planting place: "Do you understand? ”

Ma Xinyi and the others were looking at Yang Bo teaching these students with a smile, and when they heard Yang Bo's words, Ma Xinyi was stunned, and he asked with a panicked face: "What?" Small, the villain didn't understand ......"

Yang Bo leaned over to the student and said, "You said that the way to cover the quilt is good, but whether it works or not we have to test it to know." Right? ”

The student nodded excitedly: "Yes, the teacher often says this"

"Alright, then I'll appoint you as the team leader in charge of the care team for these sweet potato fields. What do you think? ”

Yang Bo said with a smile on his face: "You don't have to do the work, you just need to command them to do it, you are responsible for the observation on weekdays, record the results and report them to me, if it works, in the future, all over the Tunpu will promote this method named after you, okay?" What is your name? ”

"My name is Kong Ergou. They all call me nickname, Ersuno."

Yang Bo said with a smile: "Well, our method of covering the quilt is called Kong Ergou greenhouse." Or a two-sunspot greenhouse, which one do you choose? ”

Before the student could answer, the students around him laughed: "Ersuniko, Ersunzi greenhouse is good!" ”

"Then we're decided!"

Yang Bo punched him in the chest. got up and said to Ma Xinyi: "You organize people." Build a shed on the side of these temperature-loving crops, cover them with a cotton canopy at night, and remove them during the day, you have to master the different suitable temperatures of different crops, and record the results as standard teaching materials for promotion. What if there was some fire in the greenhouse? Maybe we can all grow vegetables in winter, why don't you give it a try? ”

Ma Xinyi hurriedly replied: "Yes!" The villain organized people to try to plant a few acres this winter."

The poor child is sensible early, and another older student retorted, "Teacher." Just said that the fire was lit, but you said that it was unrealistic. Isn't it unrealistic to add a quilt now? If sweet potatoes are to be promoted on a large scale in the future, if there are 100 acres, 200 acres, or 500 acres of sweet potato fields, how can so many people come to lift and cover them? ”

"What's our school motto?" Yang Bo asked suddenly

The students read aloud, "Clear goals are the driving force for progress!" ”

Yang Bo laughed: "If we confirm that the quilt is effective, then we can find a way to solve other problems, for example, how about we use glass to build a greenhouse?" You see, this not only satisfies the warmth, strengthens the sunshine, but also does not need to be taken care of manually, you can count it in one fell swoop, right? Now that glass can't be made in large pieces, can we replace it with a lightweight material that can transmit light, but can also keep warm? What we're doing is focused on how to solve the temperature difference, so I think you'll have more ways to solve the problems that come with solving the problem in the future, right? ”

Some of the students were patting their chests, some were thinking, and they all wanted to come up with a different way to get the teacher's approval......

Yang Bo said to Ma Xinyi: "Your company should quickly formulate a plan to promote greenhouses, and submit it to the Finance Department for approval. ”

Ma Xinyi nodded a little ashamedly and said, "Yes!" ”

At that moment, Yang Bo asked everyone again: "The fertility of the land is not enough, what is the solution to it?" ”

At this time, the people in various divisions did not dare to slack off, and they thought about it one after another, most of them were from farming families, and they had experience in farming on weekdays.

The next person came out of the crowd and saluted Yang Bo before saying: "My lord, the villain has heard of a method, according to the people in Liaodong, after the alfalfa is harvested, some stems and leaves can be left to be mashed and piled up in the field, and the fertility of the land will be restored a lot next year."

Yang Bo was overjoyed and said to Ma Xinyi: "Record it for testing"

"Which division are you from?" Yang Bo asked

"The villain is Xue Xinyang of the Department of Assistance and Resettlement of the Displaced People, and I have heard the displaced people from Liaodong talk about this matter before," Xue Xinyang bowed and replied

Yang Bo nodded, turned around and asked the student, "Do you think Master Xue's words make sense?" ”

The students were a little confused, and many nodded and hesitated.

"If you want to know if it makes sense, let's think about it first, what are the ingredients in the land, for example, we are on the seaside, and the soil has a salty taste, why, the salt content is high, do you want to taste it?"

So at the instigation of Yang Bo's ill intentions, all the students grabbed the soil with farmhouse manure and put it in their mouths to taste it......

"As we said just now, crops and people have to eat, let's eat, they eat useful things in the soil, there are many things in the soil, some are useful for crops, some are excessive, and they are harmful to crops, like high salt content, right? So what exactly is in the soil? Don't underestimate such a small problem, it contains a big world, a new world that no one has ever seen, your parents have never seen it, your grandparents have never seen it, and now you are standing at the door, you may need to read more books, and you will spend some time experimenting, I look forward to you opening the door to this world one day, okay? ”

The students were spitting sand and patting their chests in reassurance.

At that moment, someone stepped forward and said: "Adult, the villain is the Jimo people, we often use grass ash and quicklime on the beach to improve the soil quality."

Yang Bo nodded and said to Ma Xinyi: "I also have a few methods, you try them one by one, add bone meal to the field, such as fish bones, chicken bones, pig bones, etc., grind them into powder and add them to the ground, and there is another one, isn't there a large area of silt on the beach?" I heard that bat manure in the cave is also an excellent fertilizer, and some seaweed can also be used to fertilize the field, and finally there is a way, now the farmer's fertilizer in our fertile fields is raw fertilizer, we have to turn them into mature fertilizer, how to change, compost, the way is like this......"

Everyone looked at Yang Bo with surprise on their faces, and Ma Xinyi nodded while recording Yang Bo's words, for fear of missing a word.

After Yang Bo finished speaking, a student asked curiously, "Teacher, how do you know that these methods are effective?" ”

Yang Bo thought for a while: "I don't know, but I hope you will know in the future"

At this moment, Zhang Fengjin walked over with Han Fangmei and a few others with excited expressions, shouting all the way: "My lord, the plaster you want is fired, it is very useful!" ”

Needless to say more about Zhang Fengjin, everyone had already seen Han Fangmei holding a plate, on which two bricks were firmly glued together at 90 degrees...... (To be continued......)
