Chapter 160 The So-Called Three-High Agriculture

Although Li Sheng and Thomas didn't know how big the snake was, it would certainly not be too small to swallow a 180-pound calf.

Thomas knew that they couldn't completely prevent the snake from entering the hinterland of the farm now, so he had to put this matter aside for the time being.He said: "Lee, there is another problem on the farm. Last time we searched, we found a lot of newly dug mouse holes in the pasture, and this time we found more. That proves that there are more and more mice on the farm. I think we need to do something in advance."

Li Sheng had long thought about preventing rat infestation, but he couldn't think of a good way.Cows need to eat grass, and drugging is definitely not an option.I'm afraid it won't have much effect.

He sat down on his desk and said, "Pudin and the three servals often come home with mice in their mouths. There are more and more mice, and I have noticed it. It's just that I don't know how to prevent the proliferation of mice."

The danger of rats is not only to destroy the grassland, but also because they are carriers of dozens of viruses and bacteria that can endanger human health. Of course, Li Sheng does not want rats to occur on the farm.

Thomas had been thinking about how to deal with the python, and he hadn't thought about how to solve the problem of the rapid increase of rats.He was just reminding Li Sheng this time.

He thought for a while and said: "Elimination of rats requires the efforts of everyone on the farm. For example, reducing rubbish and so on. But I don't think those rats may need to find food from the rubbish dump, and the root system of the pasture can provide them with enough food. .”

"That's the worst, isn't it?" Li Sheng let out a breath.He opened the door of the office, glanced at the prairie stretching beyond the horizon of the office area, and said. "As long as there is pasture, these mice will not starve to death. When the number of mice reaches a certain level, the pasture will all disappear."

"Maybe we can raise some cats." Of course Thomas knew the best snake catchers, but he couldn't let Li Sheng introduce snakes.Because the strongest thing to catch mice is poisonous snakes.Although snakes have strong mobility, they are obviously not as fast as mice.Most of the things that can kill mice in large numbers rely on venom.How could he let Li Sheng introduce a large number of poisonous snakes.

But having said that, if there are always more rats on the farm, poisonous snakes will inevitably enter the farm.

Li Sheng thought about it for a while, and felt that there was only one way now: "You can raise some cats, but around houses and warehouses, where cattle rarely come, you can use rat poison and cages."

"I'll discuss it with Zhang." Thomas had no choice.There are also some woods on the farm. There are many owl-like birds in those woods. There is also an unknown big-eared fox inside the farm, and they all eat mice.It's just that there are too few of them.

He suddenly smiled and said, "Li, maybe after a while, there will be more wild animals on the farm. This mouse is an animal at the lower end of the food chain."

Li Sheng had also considered this issue before.He smiled wryly and said: "I hope that the number of those animals will be enough before the rats become a problem. Of course, it is best not to have a single snake."

"But that's impossible. Isn't it?" Thomas shrugged. "Maybe we can stock up on some viper serum in the infirmary."

Li Sheng didn't want the whole farm to be full of poisonous snakes.He thought for a while and said, "Let's hold a meeting and find a way!"

Soon several senior officials of the farm were called to his office.He told about the possible outbreak of rats on the farm at any time, and asked them if they had any good solutions?

When they thought about it, they found that once a rat outbreak occurred on the farm, various problems might follow.This is also the only way to rebuild a balanced ecology after destroying the ecology.But in this process, farm workers will face a crisis in safety, which they do not want to see.A few of them racked their brains and couldn't think of a good way to avoid the next possible crisis.

Zhang Feng was an old man, he kept silent all the time, because he knew that the situation on the farm was quite special, and those common methods of catching mice were not suitable for Silent Farm.When everyone couldn't think of a new way to be rejected, he suddenly proposed: "Why don't you find Feng Xiaoting and see if he has a solution."

He just thinks that Feng Xiaoting is the most educated on the farm, and it is said that he is also a genius.Maybe he'll find a way.

Several people held a meeting for a while, but couldn't think of any good solution, so Li Sheng had to ask them to go back and think again.Although he didn't have much hope, after the meeting ended, he followed Zhang Feng's suggestion and came to the laboratory.

This laboratory occupies a large area, at least two thousand square meters, but there are more than two acres of farmland, and the rest is the real laboratory.Although the building here is also a modular structure, the overall decoration may be the best in the whole farm except his villa, and it may even be the most expensive.

It was completely built in accordance with international cleanliness standards. In this humble two-story building, various equipment worth more than 320 million US dollars were placed.One of the 3000 million magnification electron microscopes is worth more than [-] million US dollars.It is said to be the microscope with the highest resolution and the largest magnification in the world.

Going in for the experiment required disinfection, changing clothes, etc., he was too lazy to bother and didn't go in.Instead, he called Feng Xiaoting to come out, and he waited in the yard behind the laboratory.

The cultivated land in this yard is a standard glass greenhouse of [-] square meters.Wheat and rice are being grown inside, which are experimental control groups.And the doors of these greenhouses were locked, and he had no key.

Three minutes later, Feng Xiaoting came out wearing a white coat, a white cap on his head, and a mask on one ear, just like a doctor who just came out of the operating room.

"Mr. Li, what do you need from me?" Although he was somewhat dissatisfied with what he was doing, Feng Xiaoting knew that Li Sheng was his bread and butter.At least Li Sheng's investment in experiments is still very generous.In other places, even if he can participate in the experiment he wants to do now, he can only be one of the humble experimenters, and it is impossible to be the leader.So he doesn't need to give Li Sheng face.

Although the leader is very hard now, and he doesn't even have a qualified assistant, at least he can conduct experiments according to his own ideas.This is a condition that cannot be given to him in any country.So Li Sheng called him to come out, but he didn't take Joe, and immediately put down the work at hand and came out immediately.

Li Sheng saw him and said, "Yes, I want to ask you something." But he didn't immediately ask him if he could solve the rat problem.Instead, he looked at one of the greenhouses and said. "How's the experiment going on here?"

Feng Xiaoting was very clear about the various greenhouses in the backyard. He opened his mouth and said: "So far, it is relatively optimistic. The germination rate of the treated seeds can reach more than 96%, and the growth rate is quite fast. Although it is in a greenhouse There are many artificial control factors in the field, but the growth rate is about 10% higher than that of the original species planted outside. This is a good adjustment. I just don’t know the yield, and it is not yet certain whether it can achieve the goal.”

The purpose he said was Li Sheng's request to sterilize the second generation of seeds produced by these crops.Although he knew it was impossible, he should be able to control the output.Of course, he doesn't want to tell Li Sheng about this result now.

Because this experiment will take at least five or six months to get the results, everything said now is false.

He then talked about some things about seed experiments, mainly about data, without too many technical terms.

What Feng Xiaoting said was very simple, because he knew that what he said was complicated, and Li Sheng might not understand it.

Li Sheng's knowledge of biology is indeed superficial.He doesn't understand things that are too professional, such as changing the reproduction and cell division of seeds by changing the transformation of gene base pairs, etc., it sounds like a headache to him.However, I heard that the experiment went well, and it may take another half a year to get the final result.

If you are unlucky, you may never be able to breed "no more than three generations" of sterile seeds.

Li Sheng knew that Feng Xiaoting had tried his best, because he had already said that this was not a genetic modification, but that it used chemical and physical action to catalyze the mutation of the original gene of the seed, and this kind of catalysis was not 100% successful.

He nodded and said, "I don't understand professional things, I just want to get what I want as soon as possible."

Feng Xiaoting thought for a while and said: "Actually, I understand what you think, Mr. Li. In fact, there is no need to sterilize the seeds. It takes a lot of time to prepare every time you want to select the seeds that meet your requirements."

"Well, what do you mean?" Li Sheng's face was a little unfriendly. "You didn't say that before."

"This is also the problem I found in the experiment." Feng Xiaoting didn't feel any burden because of his dissatisfaction, and told the truth. "In this experiment, after each batch of original seeds has been processed, at least three generations of seeds need to be tested to get the results. But even with the most suitable method, it is impossible to make those seeds 100% sterile in the third generation, as long as there is one plant that can Cultivate fruit, and the seeds are actually leaked out. Even if a certain time is 100% successful, if you want to get the seeds you want, you need to start from scratch. And no one can guarantee that the new experiment can be 100%."

Li Sheng understood what he meant.Even if this experiment is successful, he still can't sell the grain produced by the second-generation seeds directly, let alone sell the grain produced by the first-generation seeds as seeds.

His frown deepened, this is not a good time to pursue him for not raising this objection before.He asked, "Then what do you think?"

"Mr. Li should know about hybridization." Feng Xiaoting adjusted his glasses and said. "We can completely make these grains genetically unstable in the second generation of seeds, and prone to genetic mutation after the third generation. Every generation after that is prone to mutation. I don't think anyone would want to grow such grains. "

Li Sheng looked into his eyes: "Why didn't you experiment with this idea before?"
