Go back to the past and be a schoolboy

Chapter 47 Believe in Potential
Believe in the wisdom of the working people, part of the work of selection and breeding can be completely handed over to the common people.

When putting forward this point of view, Guo Shouchun strongly opposed it: "Old Cheng, I know that you are doing it for their own good, and I also understand that with the influence of that uncle, selective breeding is a very scientific thing, and it is necessary to select excellent parental materials and To configure a suitable hybrid combination, after the selection, the combination method must be determined. In addition to the single cross of two parents, multiple crosses of more than two parents are required, including three crosses, four crosses, and sequence hybrids of more than four parents."

"This is not over yet. Obtaining hybrid seeds through various methods of hybridization is only the first step in creating the required genetic variation. The breeding of new lines and varieties requires a series of treatments and experiments. However, in the hybridization of a pair of pure line parents of wheat, the hybrids do not segregate in the first generation, but continue to segregate in the third and fourth generations, and the plants in the hybrid groups of the fifth and sixth generations tend to be homozygous. produce genetically stable offspring."

Cheng Nuo watched him say such a long sentence, poured out a bowl of soup and handed it over.

Guo Shouchun resigned, with a temper: "Old Cheng, I know you want to make them full, but science is not a joke, it is rigorous. You told me about the illiteracy rate in the Republic of China some time ago?"

Cheng Nuo blurted out, and said the statistics of later generations: "About 80%, the southeast coast is lower, and the northwest inland is higher."

"Look, I'll just say it." Guo Shouchun spread his hands together: "It is estimated that many people can't write their own names, how could they be able to do this job."

Cheng Nuo smiled, finished the soup in the bowl by himself, and wiped his mouth: "Old Guo, our farming people have cultivated the land in their bones. After thousands of years, we will not just watch the sky for food."

Take out a notebook from the carry-on luggage, turn to one of the pages and hand it to Guo Shouchun: "Old Guo, take a look for yourself."

With suspicious eyes, Guo Shouchun took a look at him, took the notebook, and read aloud the marked paragraph: "Take wheat seeds, and you can get them when they are ripe. Exposure makes it extremely dry. If there is no order, there is white fish, and if there is any, it will be treated. Take dried moxa and store it, a stone of wheat, and a handful of moxa; hide it with pottery and bamboo. If it is planted at the right time, the harvest will double."

Since it was classical Chinese, Cheng Nuo was not good at it since time travelling, so he specially excerpted this passage.

After he finished reading, Cheng Nuo explained: "This is a passage in the "Book of Fansheng". In the first year, 'choose the ears to be strong', and in the second year after sowing, 'the harvest will be doubled'. Such a simple truth We have known it since the Han Dynasty. It is true that science is rigorous, but agriculture is different, and it needs to be down-to-earth and rooted in the soil of the countryside.”

In fact, the power to mobilize the working masses was brought into full play by us later.

For example, the old lady of Zuoqiaosheng in Qilu Province discovered an excellent plant from the erect peanut in 1944. In that war-torn era, after various difficulties and continuous cultivation, she launched a variety called "Fu Huasheng", which matured early, It has high kernel yield, low temperature resistance, and good drought resistance, and can adapt to both the north and the south.

Another example is the well-known late japonica rice variety "Laolaiqing", which was bred by Chen Yongkang, a farmer, using the method of "passing on one ear".

After liberation, due to the mass seed selection campaign, the enthusiasm of the majority of farmers was greatly encouraged, and a large number of peasant seed selectors emerged.

Of the more than 2 excellent varieties, about 2/3 were bred by farmers from all over the country.

It's not that reading books is useless, after all, the method of seed selection needs scientific guidance, but that it needs to take root in this land.

Cheng Nuo saw that he was still thinking about this sentence, and took advantage of this time to make himself a bowl of shepherd's purse soup: "Old Guo, in so many places across the country, there are spring wheat and winter wheat, and you can run here with only one pair of legs." Well, even if you can run over, how long will it take?"

"So what's the matter, just use these legs to measure the great rivers and mountains of the motherland." Guo Shouchun didn't care about himself, and then questioned: "Even if I agree with you to mobilize them, why do they support us, have you considered it?"

"Because of thinking about it, I feel that this method is feasible."

"No, why did you think about it and think it's okay?"

Cheng Nuo pointed to the clay pot and explained, "It's because they don't have enough to eat or wear warm clothes, so they are more motivated to do this. Nothing is more important than being able to have a full stomach. Although there are more people who question us, as long as a town has If one out of 1000 or 1 people try it, the method will be effective, and it will be much easier in the coming year.”

Looking at the wheat fields in the distance, Cheng Nuo said with emotion: "We do this for ideals, they do this for survival, and they deal with wheat seedlings every day, so they must see the potential of this door."

Guo Shouchun was thoughtful after hearing this, and wanted to have a bowl of shepherd's purse soup, but when he opened the jar, only the bottom remained.

"Old Cheng, old Cheng, you are too rude."

After the convoy arrived at Xiaowang Village, they stayed for a while. Cheng Nuo and the others left after inspecting and continued to walk in another direction.

He was to investigate the countryside, while Guo Shouchun was to inspect agriculture. The two cooperated with each other, and the investigation progressed rapidly.

A few days later, the inspection was over, and the two returned to Beiping City with a full harvest.There is sadness and there is joy.

The sadness is that the countryside is so desolate. Many farmers would rather sell their land to escape famine in order to evade taxes. As a result, local governments cannot collect taxes, so they increase taxes again, such a vicious circle.

The joy is that many farmers retain their simplicity, and they will not abandon that piece of land as long as there is a glimmer of hope.The country gentry heard that the new seeds will be promoted in the future, except for a little doubt, they are more supportive, and expressed their willingness to take part of the fertile land as a test field. After all, this land is becoming less valuable every year, so why not do it with a yield of one hundred catties? .

When he got home, he saw the green bricks in the yard, and Cheng Nuo called Li Laosan over: "Lao Li, call some people to remove all the bricks on the ground tomorrow, just save the walking ones."

"Okay, but sir, what are you doing with this beautiful big yard? I was thinking about buying some small goldfish at the temple fair one day and setting up a big water tank for you to raise."

Cheng Nuo squatted down, opened one to look at the soil below: "What do you want those fancy things for? You have to change fish fry frequently. It's a pity not to grow anything on such a large piece of land. When the time comes, you can grow wheat in the front yard. Vegetables in the backyard."

During this trip, Cheng Nuo's planting genes were completely excavated. Now that he came back and saw this open space, he felt itchy all over his body, and he felt sorry for not planting anything.

"No problem, I will make it beautiful for you, sir, but why do we have to grow wheat?" Li Laosan was puzzled.

Cheng Nuo explained: "Experimental field, you have to experiment first, right? Then you learn more from Mr. Guo and ask him to teach you how to select and breed seeds. It just so happens that you have been dealing with wheat for decades. Get started. It must be soon, when the time comes, I will set up a peasant school and let you become a teacher."

"I can also be a teacher?" Li Laosan was a little unbelievable, surprised and happy: "Just learn from Mr. Guo and take care of this wheat field, right?"

Cheng Nuo encouraged: "Yes, Lao Li, I like you."

After hearing the definite answer, Li Laosan's face flushed with excitement, and he immediately said that now he was looking for someone to lift the floor.

Cheng Nuo stood up and patted the dirt on his hands, touched the old apricot tree in the yard and looked up, talking to himself.

Spring is here and it's time for the old man to sprout.
