Chapter 191 Manufacturing Core Containers!
Hearing this, Liu Wei, who was sitting in the co-pilot seat, immediately pricked up his ears.

"Yes, but I can't talk about learning from me. I don't know much about botany and wheat hybrid technology. I just read some basic related knowledge, and we can discuss and study together." Yu Hua heard this, smiling, not surprised Lin Lin Wan's request: "However, are you not going to engage in machine tools?"

Lin Wan's talent lies in the field of mechanical equipment. After a long period of contact and communication, he found that Lin Wan's direction is to engage in the research and development of machine tool equipment.

The importance of machine tools is self-evident, and industrial development is inseparable from the support of machine tools.

However, one is a machine tool, and the other is a hybrid of plant and wheat. The span between the two disciplines is so large that it can be regarded as impossible.

"Learning botany and wheat hybridization technology does not affect my research in the field of machine tools. I believe I can do it. Although I am not as smart as you, I am at least better than 99% of my peers." Lin Wan's face was firm, her eyes revealed A touch of confidence.

Yu Hua looked at Lin Wan who was full of confidence, nodded with a smile, and gave a thumbs up to his right hand. He was worthy of being the top student who once occupied the school's number one position for a long time. Many people couldn't compare with this momentum and self-confidence alone.

He did what he said, and the execution was full. In addition, Yu Hua just wanted to inform the hybrid technology and started the class directly.

"In this case, hurry up and talk about my views on hybridization technology. I think the key to wheat hybridization lies in the use of artificial sexual hybridization to 'de-male and female', rather than asexual hybridization."

"Because wheat is a self-pollinating crop, it is a hermaphrodite. To achieve successful hybridization, it is necessary to emasculate the female parent and pollinate the male parent. This process is very difficult, and the male flowers need to be removed manually."

"The first-generation high-yield wheat should have excellent traits such as early maturity, high yield, strong tillering ability, and a thousand-grain weight of about 30 grams.

"Well, how to deal with stripe rust?"

Stripe rust can be called the Black Death of wheat. Once infected, it may lead to a large-scale reduction in production, or even complete harvest.

"This is the focus of the cultivation of the second generation of high-yield wheat. You can introduce hybrids with strong disease resistance traits to obtain early maturity, high yield and disease resistance traits. The yield per mu is stable at more than 300 kilograms. Our top priority is to solve the problem of high yield first, and then solve the problem of disease resistance. ."

"Understood, I'll take a note, by the way, what does tillering power mean?"

"Tillering power refers to the branching of grasses and other plants below or near the ground. The popular meaning is heading. Early heading and fruiting tillers are called effective tillers; ."

One person explained and the other took notes. Liu Wei did not disturb Lin Wan, who was earnestly studying valuable knowledge, nor did he disturb Yu Hua, who was like a teacher. He who had no professional knowledge at all, only knew one thing—keep quiet.

The Buick was driving smoothly. Beiping City was about 260 miles away from Zhao Beikou of Baiyangdian, and it would take some time to reach the destination.

The farther away from Peiping, the more primitive the surroundings become, and the roads gradually become bumpy. There are no cement roads these days. The better ones are cinder roads and gravel roads. The most common ones are dirt roads. The road infrastructure construction is basically zero.

Cement, which is a real strategic material, is very scarce. Only the capital and Nanjing, as well as a few large cities such as Peking and Tianjin, have paved cement roads and asphalt roads.

Regarding roads, it is actually very interesting. The roads of the Republic of China first began with the "Regulations on Road Repair" issued by the Beiyang government in 1919. Later, the Nanjing Railway Department issued road construction standards in 1927. The embankment is 12 meters wide, the roadbed is 9 meters wide, and the road surface is divided into There are four grades A, B, C, and D, and the materials used are crushed stone, gravel, river mud and soil.

Although the road stays at the gravel road level, there is finally a construction standard.

Later, in 1932, the Nationalist government held the 'Seven Provincial Highway Conference' in Hankou to formulate the standards for the liaison highway engineering of the provinces.

This time, the technical standards of road engineering are getting closer to perfection. It is stipulated that the road surface is divided into six grades: dirt road, gravel road, muddy gravel road, boulder road, brick road, and asphalt cement road. Meter or 12 meters, the bridge load is 9 tons and 9 tons.

From 1919 to 1934, it took a full 15 years for the Nationalist government to improve the road construction standards on paper. However, the things on paper were all bluffing things, but in reality they were all dirt roads.

For the Republic of China, it is a century-old project that cannot be completed in a lifetime, and it cannot be done with the strength of the whole country.

She taught Lin Wan along the way. As the former No. [-] in the school, Lin Wan has a very high talent and memory. She can quickly remember what Yu Hua said, and she can draw inferences from one case, occasionally put forward targeted suggestions and questions. As time went on, after talking about the few knowledge of plants and agricultural technology, Yu Hua found helplessly that he seemed to have nothing to talk about.

There is no way, Yu Hua really doesn't know much about plants and agriculture, and his understanding of hybrid wheat is even more rare, basically staying at the principle level.

Mendel's laws of inheritance, segregation of traits, asexual crosses, sexual crosses, male-sterile lines, etc., are things he understands.

More than ordinary people, but definitely not as serious as botanists.

Well, he is a bit too big. It should be the first-year students of agricultural universities in later generations. The deep technical and professional knowledge in the agricultural field also needs to be systematically studied.

"The main feature of male sterility in plants is that the stamens develop abnormally and cannot produce pollen with normal functions, but the pistils develop normally and can receive normal pollen for fertilization and fruiting. Finding male sterile plants is the key to realizing large-scale hybrid wheat applications. , what I know is roughly this, the next thing in learning, you need a real teacher." Yu Hua finished the explanation of the importance and value of the male sterile line, as well as the basic concepts, and ended the explanation of this trip.

This knowledge may seem trivial, but in fact, it is all the valuable experimental experience summed up by later generations of Yuan Lao. Rice and wheat are both self-pollinating crops. Artificial emasculation may seem simple. It is not possible to emasculate all in one year.

Therefore, it is crucial to find stable male sterile plants to break wheat selfing.

Lin Wan took notes, raised her right hand, rolled up some blue silk and put it behind her ear, her eyes showing curiosity: "Male sterile plants... This kind of individual should be difficult to find."

"It's more than difficult. From a probabilistic point of view, about [-] plants produce one male sterile plant, and you have to find it during self-pollination. The time is very short, which is even more demanding than finding a needle in a haystack." Yu Hua shook his head. It is said that the difficulty of finding natural hybrid parents of wheat is ten, then the difficulty of finding male sterile plants is as high as one hundred.

Finding male sterile plants is an extremely time-consuming and laborious tedious task. This is true of wheat and rice. It took Yuan Lao several years to find a natural male sterile plant. After artificial pollination, hundreds of first seeds were produced. However, in a later experiment, more than 700 sterile seedlings were all pulled out and destroyed. If the remaining 5 seedlings were not found in an abandoned well, the super hybrid rice would never have come out.

"There is nothing difficult in the world, I'm just afraid of those who have a heart. No matter how difficult it is, I will continue to do it, Yu Hua, thank you." Lin Wan did not back down when she heard what Yu Hua told her, but her expression became more determined.

"Let's help each other." Yu Hua raised his right hand. The food issue cannot be ignored. However, cultivating high-yield wheat is too time-consuming and laborious. Human energy is limited. He can't devote himself to the field of breeding. He can only hope that Lin Wan can cultivate Qualified high-yield wheat.

"Together."

Lin Wan smiled, raised her right hand, and gave Yu Hua a high five.

The weather was getting hotter and hotter. At around five o'clock in the afternoon, it was already dusk. Accompanied by a billow of smoke and dust, the Buick car entered Zhaobeikou along the dirt road.

Zhaobeikou is close to the east bank of Baiyangdian Lake, facing Tianjin in the east, Baoding in the west, and Beiping in the north. It has an important geographical location and is rich in water resources.

Today, most of Zhaobeikou is in a rural state and has not been developed. The experimental site of Yu's Seven Pagodas is located in Liu Village, south of Zhaobeikou.

The Buick car came to the entrance of Liucun Village and stopped steadily.

The group arrived at the destination, got off the car and entered the village. Yu Hua curiously looked at the rural North China in 1937. Most of the surrounding houses were earth-walled houses, there were a few brick buildings, and there was no infrastructure such as wires at all, and the economic level was extremely backward.

Not far away stood a few unkempt children, both male and female, staring at Yu Hua and his group cautiously.

Yu Hua looked at these children in patched clothes and sighed in his heart. The reason he sighed was not because these children were wearing patched clothes, but because these children had reached the age of education, but they could not enter the school.

The reason why the Republic of China has so many masters is based on the high illiteracy rate in China.

Perhaps, among these children, there are talented scientific research seedlings, but because they cannot get a complete education, they can only farm to make a living.

"The experimental site is in front. All the purchased machinery, equipment and materials have been shipped and placed in those brick buildings. Thirty tons of sulfur are piled up near the experimental site. You asked me to find about ten welders, and all of them have arrived. , these people in the village are people I can trust." After entering the village, Lin Wan, the deputy team leader, slowly introduced.

"Jin Yu, I want to pay for some books, set up a library in the village, let these little guys read the books, the money goes to my personal account, let's pay 10 yuan ocean." Yu Hua stared and hid behind the corner full of curiosity And the children who looked in awe, said softly.

In the eyes of the rich, 10 yuan may only be enough for a meal, but it can buy books that change fate.

Although he couldn't change the current situation, Yu Hua still chose to do something. At least, let these little guys have access to things that change their destiny.

Knowledge, the crystallization of human wisdom.

Since ancient times, the value of knowledge is immeasurable, completely equal to life, and even some advanced knowledge far exceeds the importance of life.

"Library? It's a good idea, then I'll pay 10 yuan."

Lin Wan was thoughtful, her eyes brightened, she nodded in agreement, and turned to Liu Wei and said, "Old Liu, trouble you."

"I wrote it down." Liu Wei was deeply touched, and when he saw the other side of Yu Hua again, he nodded silently.

It didn't take long for the group to enter the village, and soon a figure of a young man appeared and greeted them.

"Miss, Mr. Yu, Steward Liu." The man stopped in front of him, his forehead covered in sweat, and greeted everyone in turn.

"This is the person in charge of the construction of the experimental site, He Wenlong." Liu Wei introduced at the right time.

Yu Hua stepped forward with a kind and natural smile on his face, and extended his right hand towards He Wenlong: "Hello, Master He."

"Hello, Mr. Yu."

He Wenlong was obviously a little flattered. He didn't expect Yu Hua to be so polite, so he quickly stretched out his right hand, shook it with both hands, and then released it.

"Just call me classmate Yu, Master He, please take us to the experimental site to see." Yu Hua responded.

He Wenlong, who received the notice long ago, nodded again and again: "Okay, classmate Yu, miss, please come with me, the foundation of the experimental site is almost completed."

When the words fell, he turned and walked towards the village.

Yu Hua and his party followed He Wenlong's footsteps to the experimental site and passed through the center of the village. Soon a scene of heat came into view. Hundreds of workers formed a circle and rammed, and lifted heavy wooden rammers through ropes until they reached the highest point. Then he pulled down hard, causing the heavy wooden rammer to hit the ground and tamp the foundation.

"Bang bang bang!" The dull crashing sound kept coming out, and the helper sang while observing the ground.

The foundation covers an area of ​​about 150 square meters and is almost complete. Sulfur is piled up on the left side of the foundation, and there is a newly dug pool on the right side. The pool is connected to a small river tens of meters away, and the small river is connected to Baiyangdian Lake.

"Student Yu, we all follow your requirements. Do you see anything that needs to be improved?" The group came to the periphery of the foundation construction site, and He Wenlong stood in front and respected Yu Hua.

There is nothing to despise the white-faced scholar, and there is nothing to sell qualifications. He Wenlong clearly understands that the life and death of the entire experimental site is decided by the young genius student in front of him.

"I can only say... It's good to have money, Jin Yu, take the liberty to ask, do you have any mines at home?" Yu Hua shook his head, and was not dissatisfied with the foundation in front of him.

Not satisfied?
No.

In the era of relying entirely on manpower, the foundation was completed in a few days, and the number of workers was as high as hundreds. For such behavior, Yu Hua can only say that it is good to have money.

Lin Wan's mouth twitched, her face speechless: "..."

I really want to hit people.

"Let's go back and prepare to manufacture the core container." After seeing the foundation construction site and confirming that there was no problem with the quality, Yu Hua relaxed and said to Jin Yu.

Lin Wan nodded, and then the group returned to the village and immediately started to work. Lin Wan found the design of the core container that had been transported to Liu Village not long ago, and Butler Liu was responsible for finding people and arranging ten welders to be present and responsible for generating electricity. Ready to make core container.

"Boom!" Soon after, the noise of diesel generators came from the village. This is a diesel engine imported from Germany. The manufacturer is MAN. It can stably provide 50KW power at 15 Hz. The power output is stable and the work is reliable. The only shortcoming just expensive.

Generally, electric welding machines do not need this stuff at all, and the cost is too high to bear. However, as a submerged arc welding machine of electric tigers, it must be powered by this stuff to meet the needs of use.

Electricity is the foundation of modern industry and electronic technology. Without electricity, human beings will instantly return to the primitive world.
