Siheyuan: I eat melons while doing scientific research

Chapter 1222 The virus can no longer occupy the high ground (4k)

It turns out that the variety of Qianyu-63 is more ideal than the others, and the biggest difference is the cumbersome seedling raising procedure.

As for other differences, such as tillage depth, planting density, temperature, time, etc., based on the work experience and qualities of Comrades Zhang and Li, the impact on variety degeneration should not be that great.

It now seems that, unless it is a genetic advantage, the biggest "suspect" is this seedling breeding procedure.

Assume that it is precisely because of this procedure, combined with the potato population isolation measures, that this variety or this method has excellent resistance to degradation, but why do we do this? What is the effect of doing this? What is the theoretical basis?
Problems came one after another, leaving the two researchers at a loss and faced with lawsuits. The main reason was that the method itself was new, and the things hidden behind it were even deeper.

"How about...we ask Commissioner Gao?" Lao Li said to Lao Zhang.

"Well, that's the only way. I just don't know if it will affect other people's work."

"How do you know if you don't try? Well, I'll go find a phone." Although Lao Li is usually slow, in the team formed by Lao Li and Lao Zhang, Lao Li is responsible for welding the accelerator and Lao Zhang is responsible for controlling the brakes.

But even this kind of slow-moving person, once he makes up his mind and finds the right goal, has a strong ability to take action!
Lao Zhang said, "Why are you in such a hurry? Do you know his phone number? Are you sure you can get through? I don't think you can get through to his desk even if you find the right number."

Old Li thought about it and nodded repeatedly: "Well, you have a point. So, you can work hard here, and I will go back to the province. First, I will send the potatoes to the province. There are more potatoes now. It is better not to send only a few like last year. Let him eat them well. Second, I will ask the provincial leaders to call him, so that I can find him."

It's true that although Lao Li's method is stupid, it is actually a good idea. It is unlikely that the comrades in the province will reject it. After all, potatoes are of great significance to Qianshan. Moreover, this achievement has been reported to Beijing, and everyone from top to bottom attaches great importance to it.

The only drawback is that it is quite labor-intensive. These days, it takes an extraordinary amount of time to travel from Caohai to the province.

"Okay, then you'll have to work hard. It's not an easy journey." Lao Zhang was also very curious. He saw that there seemed to be a set of technology that would be of great benefit to potato production, but he just couldn't get it. It would be nonsense to say that he wasn't itching to try it.

Two days later, Comrade Lao Li really arrived at the Zhuangyuan Building and met with comrades from the province.

A staff member received Yang Yu and heard his request. He did not hesitate and immediately reported to the leader. There was no other way. He called Commissioner Gao but he could not get through.

After listening to the staff's report, the leader of Qianshan immediately grabbed the microphone and said, "Please invite the comrade who grows potatoes in."

"Comrade Zhendong, it's me... I heard that you have a new project on some small aircraft. Would you consider our Qianshan? Qianfei Factory is newly established and really needs support..."

He called Gao Zhendong and in addition to the potato issue, he also mentioned the news that Qianfei Factory received from Qianhang.

Although Qianfei Factory is more under the vertical management of the Defense Work Committee, since it is located on the ground of Qianshan, as the local chief, it is his duty to strive for opportunities for Qianfei Factory.

"...Is that so? Ah, okay, okay, I understand. There are rules. You don't need to tell me the details. As long as Qianfei Factory can have this opportunity, it's fine... Whether they can get it or not depends on their ability... I'll be responsible for knocking on the door, hahaha..."

Three minutes later, Lao Li got the opportunity to talk directly with Gao Zhendong.

After hearing Comrade Lao Li's question, Gao Zhendong laughed. The comrades were very sharp. They had almost dug out the whole picture from just a few clues.

The reason why he didn't say anything about this is that it's difficult to explain, but since the comrades discovered it on their own initiative, it's easy to deal with. It was all discovered by the comrades and has nothing to do with me. The planting method I gave was based on guesswork.

"…Researcher Li, this is what happened. I suspect that the potato variety has degenerated and is related to viruses or bacteria…"

One of the most important reasons for the degeneration of potato varieties is viral infection. However, it is not convenient to kill the virus in one bite, so bacteria are also brought in.

Bacteria: It’s snowing in June! ! ! !
"So you designed this seedling raising program to eliminate the impact of these things to the greatest extent?" Old Li drew inferences from one example.

"Well, to some extent, that's true. From common sense, the movement of these things in the plant body should be restricted by an indicator such as diffusion speed. So my idea is relatively simple. While the young shoots have just grown out, we take them out and cultivate them separately. In this way, the virus channel will be closed from the seedling stage, and the virus will not have time to occupy the high ground. This can improve the seedling's ability to resist degeneration, or try to prevent or delay degeneration."

Gao Zhendong suddenly remembered a skit he had seen in his previous life and laughed even more happily.

"Commissioner Gao, your idea is really bold and sharp! Based on the planting and cultivation situation, we think your idea is the most likely one. It's a pity that we have limited research methods now and cannot confirm it."

Viruses are too small, and the technical means of Qianshan Agricultural Science System are currently limited. Whether through direct or indirect observation, it is difficult to clearly prove the existence of such viruses and their impact on potatoes.

But for Lao Li and his team, the issue of whether or not it can be verified is not a big deal. As long as they have a logically self-consistent theory, it will not prevent them from using experimental methods to confirm the existence of this theory and the effectiveness of the method.

This is the case with many disciplines. No matter whether the theory is correct or not, or even exists at all, at least the experimental results are like this, so we can use it first. If problems are discovered later, we can correct them later.

Things that are a little further away from ordinary people, such as fluid mechanics and mathematics, are often used as theorems when solving practical problems.

If it is closer to ordinary people, such as letting physicists study prime numbers, the style will most likely be like this.

They might assume a premise that "all singular numbers except 1 are prime" and then start experimental verification.

3是素数、5是素数、7是素数、11是素数、13是素数……你看，没问题吧，单数都是素数。

As for the 9? Well, that's a margin of error.

It may not be until 15 is discovered that physicists will begin to revise the theory.

So for Lao Li, it was satisfying to hear Gao Zhendong's conjecture on the matter in full, so as not to delay their further research. As for some regrets, that was not a big deal. But Gao Zhendong had a different idea. Since you are here, I can help you.

"If you want to confirm, it's not completely impossible."

Gao Zhendong's words made Lao Li overjoyed. Although he couldn't think of any way to solve the problem of observation and verification, since Commissioner Gao said there was a way, there was a high probability that there was a way.

"What method? Commissioner Gao, can you teach us?"

Gao Zhendong smiled and said, "No need to teach. In fact, as long as you have the means of observation, you can verify it. It just so happens that we have imported an electron microscope for scientific research. Judging from the magnification, it can deal with viruses. As long as you make a good scientific research plan, you can come to Beijing when needed. I can provide you with an electron microscope."

If we want to study this problem seriously, we must plan, add a control group, plan each stage, establish how to evaluate, etc. And breeding takes a long time. So Gao Zhendong didn't say when, but just said that as long as you come, I can help you.

Gao Zhendong imported this electron microscope for the purpose of tearing tape, but it obviously cannot be used only for tearing tape. That would be a waste, so Gao Zhendong would not do such a stupid thing. In addition to being used for metallurgical metallographic observations, it can also be used in other places.

"Thank you so much, thank you so much! Commissioner Gao, we must do a good job in this research and unravel the mystery of potato variety degeneration!" Knowing the facts is not useless, but knowing the reasons behind them will undoubtedly be more beneficial to work and future research.

If knowing the facts can only take you a limited number of steps and you will eventually hit a bottleneck, then knowing the reasons behind them will have a much broader prospect.

After expressing his gratitude profusely, Lao Li hung up the phone and reported the situation to the leaders of Qianshan.

"Food is the primary need of the people." The leaders of Qianshan learned from the report the harm of variety degeneration and the importance of conducting research on it. They waved their hands and immediately made a decision: "You will report your research plan to the Provincial Academy of Agricultural Sciences. The province will directly approve funds for you to conduct research. You must do a good job and don't let Commissioner Gao down!"

Old Li returned to Caohai happily to discuss scientific research with Old Zhang.

The other protagonist in the phone call from the Qianshan Provincial Leader to Gao Zhendong - a comrade from Qianfei Factory was on his way to Qianyang, preparing to take a flight to Beijing.

As people from the aircraft factory, they have this convenience - it is more convenient to take a plane. They don't have to wait for the pitifully few civil aircraft with terribly high requirements. They can communicate with their comrades in the Air Force and take a flight.

But before that, they had to go to Zhuangyuan Building first. Comrades from the province informed them that they had already communicated with Commissioner Gao and that at least there would be no problem in meeting Commissioner Gao. There were also some things they had to pick up to bring to Commissioner Gao.

For something like this that has not yet been decided, it is not necessary to go through the Defense Working Committee for the time being. It is equivalent to Qianfei Factory and Gao Zhendong conducting preliminary discussions and exchanges first, and then reporting to the Defense Working Committee.

Otherwise, if every little thing has to be approved by the Defense Working Committee before it can be communicated, then no one will be able to do anything.

The comrades from Qianfei Factory boarded the plane with a little surprise, carrying half a bag of potatoes and some other local specialties. They didn't know what was in the other pocket, but at least they could smell the scent of Houttuynia cordata through the sack.

The comrades at Qianfei Factory were somewhat puzzled by the comrades from the province.

——You are using this to test the cadres?

I don't understand it, but I still have to do my job. I can't understand the things between leaders.
-
While the comrades from Qianfei Factory were still trying to catch a plane, Gao Zhendong was at the National Academy of Science and Technology, carrying a heavy metal box.

In Gao Zhendong's opinion, this heavy metal box can be said to be the ancestor of solid-state drives. Yes, this thing is made up entirely of memory chips, and it also has a special battery responsible for maintaining power when power is off.

Even though it uses a silver-zinc battery with a very high energy density, this thing is still not light.

The 12th Ministry of Machine Building supported Gao Zhendong with all its might. They only approved the best ones. The tape was too slow and the magnetic core was too heavy. It wouldn't work!
Looking at Gao Zhendong's expression, the head of the Department of Mathematics, Physics and Chemistry said with a smile: "Comrade Zhendong, you seldom come home. You should come back more often. You said you would come, so why bring anything with you?"

Gao Zhendong has created world firsts in many fields. Although he has not been here many times, his comrades are still very familiar with him. The dean of the department was very pleased with the fact that the department had taken action to snatch Gao Zhendong from the siege of the 17th Ministry of Machine Building and other ministries.

Gao Zhendong raised the "solid state drive" in his hand and said with a smile: "I recently sorted out my software programs for mathematical calculations and made a set of software. I thought that comrades might need it, so I sent it to you. It's not complete, but it's mainly good at matrix calculations, and I think it can be of some use."

He started out by going all out, and doing it in a very pretentious way.

"Matrix calculation?" The dean of the department looked surprised.

"Yes, it is a general-purpose matrix calculation software, which of course also includes some other things. With this software, comrades will have to do much less programming when handling similar tasks. In addition, this software contains a large number of special mathematical tools, which are very good for actual engineering calculations."

Gao Zhendong is not modest at all. For him, the faster this software can be promoted, the greater help it will be to our technological development. In the past, we couldn't afford it because the cost was too high. Now that it has been developed, it is naturally the sooner the better.

However, whether it is Octave or MATLAB, if you really want to use it well, programming is still unavoidable. It’s just that this kind of programming is much easier than writing complex calculation formulas into C code bit by bit.

To put it simply, many calculation processes only require writing a function name, without the need to implement a full set of codes. Most of the work is done by this calculation software.

In this way, researchers can focus on the algorithm itself, rather than racking their brains and hair thinking about how to implement the algorithm in computer language.

Gao Zhendong's words immediately piqued the interest of the dean of the department. This thing is incredible! He can now think of a lot of subjects or majors that might use this thing.

The contradiction in computer application involves a pair of relationships, namely, the issue of whether the computer is "easy to use" and "good at using it".
