Corning continued to listen to Xu Hongru's explanation, and in front of him, a blueprint that I don't know whether it was terrible or great was slowly unfolding.

But the men behind him didn't know the throbbing in Kangning's heart, and they wanted to know more about potatoes and sweet potatoes.

It is said that it is an extremely abundant crop, and the land requirements are generally not high.

But instead of rushing to ask about these two things, Corning saw another high-yielding crop native to the Americas, corn.

Due to the relatively cold climate in the late Ming Dynasty, Xu Hongru adjusted the planting time of corn. Now, Corning can already see corn knee-high.

However, Xu Hongru didn't seem to notice his eyes, and he kept explaining his plan, the first step was soil fertilizer science.

Whatever is planted, soil is the most basic factor of production. Therefore, Xu Hongru did not come to the end of the Ming Dynasty with two potatoes like other traversers. As a professional, he understands the importance of soil modification.

However, due to the limitation of productivity conditions, he could not produce the exact ratio of chemical fertilizers in later generations, and could only use ore powder to reluctantly replace it.

Fortunately, the hard work paid off, and the surrounding farmers had already seen his success and began to follow suit.

Agriculture is a complex project, and in many cases, knowing the principles does not mean that you will succeed in practice.

It is not easy for Xu Hongru to do this step.

And he's had a lot of experience that he can now pass on to a lot of people, including Corning.

It stands to reason that Corning should bring people to study hard. But he's in no hurry to do so now.

Hearing that Xu Hongru had already turned the topic to soil fertilizer science, Kang Ning said impatiently: "Brother Xu, the younger brother came in a hurry this time, and the good hands of the crops in Qingzhou Mansion did not bring any of them. It's not that the younger brother is unwilling to study humbly, it's that the younger brother listened to it for a long time and didn't understand much. Therefore, the younger brother really didn't dare to bother the eldest brother anymore. I'm a stupid cow, I can't understand my eldest brother's elegant music. In a few more days. Big brother will be able to see the group of like-minded people I brought. ”

Xu Hongru is essentially a humble, simple and idealistic person, he didn't expect that he would get carried away in front of Kang Ning to such a point. I don't know what trait is in this person that makes me have such an obvious urge to vomit.

Still, he took Corning's words. Understood as an implicit exhortation, meaning that this is all your trick, we are not and voyeurism. This is a common mentality in the Ming Dynasty and even throughout ancient times.

It is also the reason why it is difficult to meet high-quality inheritors when some excellent technologies are promoted.

But Xu Hongru didn't care. He wished his cause was widely promoted. Now, if he rises up in rebellion. Success is only a matter of time. Of course, this requires the tacit approval of Huang Lin, a former ally.

Although he had the advantage of population, he knew better than anyone else that the golden finger that Huang Lin mastered was far more powerful than he imagined.

Xu Hongru did not want to become a pathfinder for Huang Lin, so he would not easily launch an uprising. He will not watch the villagers who have lived a happy life through their own efforts have to go to the battlefield.

Kang Ning still can't understand his state of mind, he only knows that Xu Hongru's current energy is enough to be on the political map of the Ming Dynasty. Leaving a large crater. If he rises up, the impact on the Ming Dynasty will definitely be many times more serious than in history.

Xu Hongru gradually recovered from the state of his excited speech, and only then did he notice that Corning's eyes had been staring at the corn.

"That's corn. The corn cob can be boiled and eaten, ground and used as feed for livestock. ”

Hearing this, Corning just asked like an ordinary native, "Is it a big production?" ”

"It's huge. It's a little worse than a potato, but I'm more willing to promote him because I have a way to make him a constant source of money. ”

Kang Ning glanced at Xu Hongru curiously. It seems that after Wang Sen destroyed the trade route, he did think about a lot of methods. This scheme should be one of them.

Corning didn't know exactly how it worked. But he knew that Xu Hongru must have used his professional knowledge to deduce.

However, Xu Hongru did not have much sense of secrecy about this plan, or there was no need to keep it secret in this regard at all.

Because this is a Yang conspiracy that has fallen and fallen, those seed stations of later generations. Those institutions and units that rely on breeding to make money have relied on this plan to earn countless huge profits. What he is doing now is just repeating the plan that has been proven to work.

The sudden change does not make any deductions, and he Xu Hongru also knows that there is no reason for this plan to fail. Unless the Ming Dynasty dared to defy the condemnation of the world, farmers were forbidden to use such extremely high-yield seeds.

That's what he wants to see, and soon the Ming Dynasty will lose the hearts of the people. Then his rebellion. It's easier to get a one-time response.

However, there is no need to explain this to Corning, he can simply state his thoughts to Corning. It's also good to let this not a simple defector know how strong his technical strength is.

So, Xu Hongru began to explain his plan. Although Corning's understanding of self-crossing and backcrossing was limited to the middle school level, and although Corning didn't understand the difference between single-handed, three-crossed, and double-crossed, he still generally understood what Xu Hongru meant.

The seeds given by Xu Hongru are excellent for the first generation of plants that grow in the ground. But the seeds left over from the first generation, the generation that determines the genotype of the second generation, will have a severe reduction in yield.

Xu Hongru skillfully used the characteristics of monocross to make the second generation of plants appear serious natural separation, so that many excellent traits of the first generation of plants, such as high yield, resistance to diseases and pests, etc., only appear on some plants of the second generation. The other part of the plant, due to the law of free combination and separation, no longer has the same excellent shape as the first generation.

As a result, most of these plants are unable to produce fruit properly, and a significant reduction in yield is inevitable.

When the farmers saw this situation, they had to buy a new batch of seeds, which was Xu Hongru's yang scheme.

Everyone who buys his seeds will be invisibly put under his shackling spell.

And he himself, on the other hand, can continue to keep the good corn seeds for those who are loyal to him.

After understanding this, Corning began to use another salt to observe Xu Hongru, who was not only a time-traveler with ideals, but also had the skills of a practitioner in their field.

"How many plants can be controlled in this way."

"The vast majority." Xu Hongru replied, "You have also seen some crops that are not subject to such restrictions. For example, the potatoes and sweet potatoes that were handed to you, and of course, the peppers and three or four kinds of pasture that you have never seen. ”

Potatoes and sweet potatoes are propagated by tubers or roots, and rely on cell totipotency for asexual reproduction. This method of using hybridization to put a tight spell on others is naturally unusable.

Speaking of potatoes and sweet potatoes, Corning suddenly remembered the problem of detoxification. Sweet potatoes and potatoes are infected with various viruses during the planting process. Because of the use of tubers for propagation, the virus will be passed directly to the next generation, where it will continue to multiply as the next generation of individuals grows.

This may cause later individual potatoes to be "highly poisonous" and become smaller, resulting in a significant reduction in yield.

There are more than 30 viruses that cause potato degradation, and there are six viruses that seriously damage potatoes: potato leaf curl virus (PLRV), potato Y virus (PVY), potato X virus (PVX), potato A virus (PVA), potato S virus (PVS) and potato spindle tuber virus (PSTVd).

Sweet potatoes are a little less dangerous in this regard, but they can't be ignored.

So how do you prevent this from happening?

Detoxification technology is the background confetti that children love came into being.

However, detoxification technology requires a lot of detail. Almost most of the operations needed to be carried out in a sterile room, and in the last years of the Ming Dynasty, Xu Hongru obviously could not have such conditions. Even if you find a relatively clean place, the dissecting microscope required by the technology can be difficult to obtain. In addition, there is a corresponding culture medium, which is also something that is difficult to obtain.

In other words, it was almost impossible for Xu Hongru to complete detoxification in the late Ming Dynasty.

Then the potatoes and sweet potatoes he relies on will have a significant reduction in production in the near future.

Then when the time comes, he can only ask Huang Lin for help.

It seems that when he put a shackle on others, he was also put on his head by others. (To be continued.) )
