"You want to breed new varieties that increase yields one at a time?"

Looking down in the greenhouse, Professor Zhao Liguo picked up the soil and observed the growth of sweet potatoes, which have now been planted for almost two months, and the sweet potatoes have begun to stretch in the soil, and they are as big as fingers.

The first month is the stage when the sweet potato takes root and grows vines, and the second month begins, when the nutrients are absorbed, the sweet potato tubers begin to expand.

Then after about two months, the sweet potato gradually grows.

The whole process took almost more than a hundred days.

This is also because of the greenhouse, which accelerates this process, if it is only a sweet potato planted in the spring, because of the temperature difference between day and night, the growth cycle will be longer.

After observing the growth of sweet potatoes, Zhao Liguo nodded with satisfaction, it was much better than he expected.

But as long as he thought of what Li Weidong had just discussed with him, he was a little big.

If it was really so easy to breed improved sweet potatoes, he wouldn't have been doing it for several years, but so far, there has been no success.

At most, the ability to resist drought is stronger than before, which is also a direction he deliberately chose.

Although he is confident that in a few years, he may be able to breed new sweet potato varieties, but that is also based on his years of experimentation before it can bear fruit.

But what about Li Weidong?

Less than half a year after building a greenhouse, I just planted it for the first time, and I wanted to cultivate new varieties?

If it weren't for his gentle personality, Zhao Liguo would have wanted to hit Li Weidong's head hard to see if he could wake him up.

"Yes, Professor Zhao, I think that since the greenhouse can provide a good growth environment for sweet potatoes, can we try to change this environment to promote the change of sweet potatoes, and even mutation?"

Li Weidong spoke his mind.

It's just that Zhao Liguo shook his head directly, if it was really that easy, it would be good.

Although the environment can prompt plants to change their growth habits, it takes a long time, and it is too slow to rely solely on the natural environment to change compared to constantly selecting seeds from the best and continuing to cultivate.

The key is that this environmental change is more about adapting to the harsh environment, keeping plants alive, not increasing yields, and completely putting the cart before the horse.

Like Li Weidong's opinion at the moment, it is a bit like relying on God to eat, and it completely depends on luck.

In Zhao Liguo's eyes, this is no different from not learning and not knowing.

But if any technician under his command said such a thing, he would definitely ask the other party to write a review of a few thousand words first.

As a technician, you should rely on your own knowledge and hard work to breed new varieties, not rely on luck or anything like that.

"What do you think...... It's a bit of a rush. ”

In the end, Zhao Liguo still didn't say anything ugly.

After all, Li Weidong is not a technician under him, and he has also heard that Li Weidong is not what he used to be, and he has become the deputy captain.

In this case, Li Weidong even invited him to discuss the cultivation of sweet potatoes, which was actually quite surprising to him.

Because Li Weidong already has a bright future.

In the past, Zhao Liguo felt that Li Weidong was smart and willing to learn, the key was to learn everything quickly, and he also thought about whether he could bring Li Weidong over and concentrate on being a technician in the future.

Now, as Li Weidong rises step by step, this idea has long disappeared.

"Professor Zhao, what if?"

Li Weidong didn't know that his opinion was a little too ridiculous.

Even he knew that the mainstream way of cultivating sweet potatoes in later generations was cross breeding.

But he didn't specialize in this in his previous life, and if he really asked him to engage in cross-breeding, he couldn't get it at all.

And it also takes a lot of time.

He couldn't have done it himself.

If it is someone else who is doing all this, even if a new variety is cultivated in the future, it can still be called Weidong No. 1?

I'm afraid it's good that his name can be touched.

So for Li Weidong, this road must not be chosen.

What he wants is to single-handedly breed new varieties of sweet potatoes.

In fact, sweet potatoes are already growing on his game farm, far more in terms of vine size and tuber growth than in greenhouses.

He believes that if he takes out the sweet potatoes in the game farm, after germination and cultivation again, he will definitely be able to retain the characteristics of the game farm to a large extent, even if the growth environment cannot be compared with the game farm, but after the improvement of the game farm, it is definitely much better than the sweet potatoes grown on the market today.

As for whether it will slowly degenerate, it will be at least a few generations away.

At that time, based on these sweet potatoes he optimized, I am afraid that new ones will be improved.

So, according to his plan, it is completely feasible.

"No in case."

Zhao Liguo said without hesitation.

He knew that Li Weidongzhi was not here, so he never forced it.

But now, in his opinion, Li Weidong is clearly impatient, and he wants to do a 'desperate fight', although he is happy, it doesn't matter if he doesn't, he patted his ass and left, to concentrate on being his deputy captain.

"I want to try."

Li Weidong said stubbornly.

It's not that he's willful, it's that he's well aware that time is running out for him.

It's been six or three years now, and even if it succeeds this year, if you want to be really successful, you have to wait until next year.

It is impossible to say that his side has succeeded, and it will be promoted nationwide next year.

That's the most ridiculous thing to do.

If something goes wrong, who can afford it?

That is a food problem that concerns countless ordinary people and countless people, and it cannot be overly cautious.

Even if Weidong No. 1 shines in the future, it is impossible to replant all of Weidong No. 1, at most it will be planted in a few provinces, and the rest will continue to be planted, just in case.

Moreover, a hundred flowers bloom is spring.

What Li Weidong needs is to light a flame to make Weidong No. 1 appear in everyone's sight, and then as time goes by, it is enough to slowly spark the prairie fire.

I never thought that when Weidong No. 1 was born, it would immediately promote such an unrealistic thing on a large scale.

But as long as Weidong No. 1 comes out, it will be enough.

The rest, it depends on time to develop.

"You ......"

Seeing that Li Weidong did not listen to the advice so much, Zhao Liguo was also a little angry, but he was more angry.

"Professor Zhao, as far as I know, the current direction of your research is clone bud variants, right? To tell you the truth, I have carefully studied the X hybrid variety, and in comparison, your improvement method is safe, but it takes too long, and it is only a directional optimization, based on the original variety, and the excellent change is made.

But this approach, no matter how it changes, has its limitations.

For example, we are now planting white sweet potatoes, although the starch content is very high and can satisfy hunger, but in terms of taste and sweetness, it is not as good as those sweet potatoes.

However, this sweet potato has not been promoted because the starch content is too low and the yield is low.

But can it be denied that this kind of red soil sweet potato also represents a kind of future, right?

If the hybrid varieties continue to be excellent, I believe that one day, this sweet potato will become mainstream. ”

Li Weidong slowly said his opinion.

He has been in the greenhouse for so long, not only with his eyes, but also systematically learned, but only that.

If he were really asked to engage in cross-breeding, he would not even be able to get it started.

"I know the sweet potato you are talking about, what's the use of tasting good? Now what people need is to fill their stomachs, what we need is high starch content, sweet or not, good or not, what's the use? ”

Zhao Liguo said a very real problem.

He didn't come from a later generation, so he didn't know what the future would bring, but now, whether it was the country or the farmers, all they needed was to fill their stomachs, what they needed was yields, and what they needed was sweet potatoes that were easier to grow.

"I know it's useless now, but it's a trend for the future, isn't it? And cross-breeding also has great advantages, in addition to sweet potatoes, sweet potatoes can also be used in this way, sweet potatoes with high starch content, and cold-tolerant sweet potatoes for cross-breeding, at least the time is short, the effect is fast, and even I firmly believe that hybrid breeding is the mainstream in the future. ”

Li Weidong had to say a somewhat cruel truth for Zhao Liguo.

As an expert in sweet potato cultivation, it is impossible for the other party to be unaware of the benefits of cross-breeding, but he still chose the direction of clone bud variants, which is itself a reason.

Because, although his method is slow to work, as long as it is cultivated, even the common people can keep their own seeds every year and plant seedlings.

And cross-breeding, with the current technology, may be good in the first generation, but the second generation may not have the yield, with too much uncertainty.

Of course, there may be changes in the future, but Zhao Liguo is looking at the present.

You can't just rely on buying seeds every year for a hundred years, right?

What if something happens?

That's why he sticks to his philosophy.

I just don't want the people to be controlled by others.

Li Weidong is very aware of Zhao Liguo's idea, according to the experience of later generations, like corn, it is basically monopolized by seed companies, and ordinary people can only rely on buying seeds from seed companies to grow.

Just because those seeds belong to cross-breeding, there is no way to keep them at all.

On a large scale, it is definitely better to hybridize, because the yield is high and there are fewer diseases, which alone is enough.

As for the role of the seed company in it, it is completely negligible compared to the increase in grain production.

It's just that Li Weidong can't use the experience of later generations to convince Zhao Liguo at this time.

But he can create a sense of crisis for the other person.

"The road is different, as long as I can increase the yield of sweet potatoes and keep the people from going hungry, even if I do nothing and am eventually replaced, I will not have the slightest complaint."

Zhao Liguo shook his head.

There are some truths that he can't understand, but he has his own insistence.

"Professor Zhao, I know what you think, food security is more important than everything, and you can't put all your eggs in the same basket, but it is precisely because of this that we should change and try more methods.

Although my proposal just now is a bit unreliable, many research inventions are discovered by accident, how can you know if you don't try it? ”

Li Weidong persuaded bitterly.

Without Zhao Liguo in his plan, he would definitely not be able to rely on himself.

It is best to convince the other party, and then let it win over a few more experts, it doesn't matter if the other party believes it or not, all Li Weidong needs is the other party's witness.

When the time comes, with so many experts witnessing, who can deny him?

Even if he is lucky, it is an indisputable fact that he has cultivated it.

Even if he chooses the name Weidong No. 1, it is his freedom.

"You are."

Zhao Liguo saw that Li Weidong looked like he would not change, and knew that it was useless to persuade him, so he shook his head again.

"You built this greenhouse, you have the right to do what you think, I can't control it."

"Thank you, Professor Zhao."

Li Weidong was overjoyed when he heard this.

He could sense the other party's emotions and naturally knew that the other party reluctantly agreed.

Whether it's messing around with him or something else, he's very grateful.

And his original plan could have changed slightly.

In the next few days, Li Weidong has been staying in the greenhouse, even Zhao Liguo has stayed, although Li Weidong wants to mess around, but he can't completely let go of it, or to save the sweet potatoes in this greenhouse to the greatest extent.

After all, the sweet potatoes here are all his painstaking efforts, and they have been cultivated several times by his Agricultural Science Institute.

Even if it has not yet reached the level of variety optimization, it is still much better than the sweet potato variety selected at the beginning.

On this day, Li Weidong found a sweet potato that looked a little different in the corner of the greenhouse, and directly inserted a sign next to it to mark it.

After a few more days, Li Weidong inserted a few more signs.

With the adjustment of the temperature of the greenhouse, as well as the change of ventilation, watering, fertilization, etc., the sweet potatoes in the greenhouse began to show a different state.

Some of them are growing well, and some are beginning to wither.

No more almost identical situation at the beginning.

And all of these were written down by Li Weidong.

Today's Li Weidong has completely become a Li technician, and every day when he arrives at the farm, he drills into the greenhouse, and occasionally the people on the farm see him, and they are covered with mud.

After Zhao Haifeng and Zhou Ji came a few times, they let it go.

Mainly, they can't control Li Weidong.

Technician Li's name once again resounded on the farm and even in the prison.

In this way, almost half a month later, there are more than a dozen sweet potatoes with brands in the greenhouse.

And all of these are taken care of.

Even Zhao Liguo slowly began to pay attention, because he found that these sweet potatoes marked by Li Weidong seemed to be a little different.

Could it be true that this blind cat touched a dead mouse?

Or is it that I am old and blindly follow the rules, so I have never made achievements?

On this day, Li Weidong was arguing with Zhao Liguo in the greenhouse about the reason for the change of a certain sweet potato, when a prison guard suddenly came to him, saying that someone was looking for him.

I don't know why, Li Weidong has an inexplicable feeling.

My life that has been 'calm' for more than half a month seems to be about to start making waves again.

He wanted to be a farmer and get Weidong No. 1 out as soon as possible, but it seemed that some people didn't want to see him not doing his job every day.

Fortunately, after more than half a month of 'research', the seeds of Weidong No. 1 have been planted.

Just wait for the sweet potato harvest to start and everything will be true.

"Professor Zhao, I think that's all for today."

Li Weidong got up and patted the dirt on his hands.

"It's okay, I know that you have a lot of things, go and get busy, I will take care of you here, and I won't disappoint your hard work."

Zhao Liguo said casually.

"Okay."

Li Weidong nodded, and then followed the prison guard out of the greenhouse.

Hey...
