Shi Shangshu's voice may not be so loud, but he is surrounded by all the bigwigs of the imperial court, and no one mentioned it before, but now that Shi Shangshu said it, everyone immediately reacted, and Zhao Shangshu of the household department reacted the fastest, grabbing the little envoy who was in charge of the title next to him and asked viciously.

"Say, how many catties of sweet potatoes have been dug up in this acre of land?"

"Back to ...... Back to the old man, ...... a total of 5,400 pounds ......"

The little envoy was just a little eunuch in the palace, who had never seen such a scene, he suddenly became nervous and stammered.

"Five...... 5,000 catties!! ”

Zhao Shiqing let go of the hand that was holding the little envoy, and his face was shocked.

At the same time, the bigwigs beside him also looked incredulous, but looking at the sweet potatoes all over the ground, they had to believe it.

To tell the truth, very early on, the household department had received Nan Zhili's official report on sweet potatoes, but at that time, the official document was only 3,000 catties per mu, and Yang Junmin, who was the head of the household department at the time, scoffed at this, thinking that there was no crop with a yield of 3,000 catties per mu in the world.

At that time, all the ministers felt that they were afraid that this little magistrate wanted to take credit and wanted to go crazy, so he made up such an absurd lie to deceive the court, which was regarded as a political achievement, and the people in the court talked about it as gossip, and it gradually subsided.

Zhao Shiqing also happened to have seen this official document at that time, so he remembered this matter, but what he didn't expect was that what the magistrate said at the beginning was not an exaggeration, but the truth.

Slowly breathing a sigh of relief, Zhao Shangshu took two steps forward and spoke.

"Your Majesty, if the yield of this thing per mu can really reach 5,000, then my people will no longer have the worry of famine, and God will give good food, this is the destiny of heaven, the emperor blessed the omen, I would like to congratulate Your Majesty!"

"Good, this Cheng Majesty is wise and martial, so he can inspire the heavens!"

What Zhu Changluo didn't expect was why this scene suddenly became like this.

It seems that these bigwigs have been able to mix up until now, and they don't just rely on criticizing dragon scales, but although the good words are good, he still has to say some things, touching his nose, Zhu Changluo waved his hand.

"Although this thing is a good seed godsend, but it is not perfect, when I was in Nanzhili, I found this thing by chance, coinciding with the famine in various places, so I ordered people to try to plant it, but the yield is extremely high, and the taste is soft after cooking, and it can be very satisfying, so that Nanzhili is all planted, but to say that the credit, it is to go to Xu Aiqing's hands!"

Zhu Changluo unceremoniously took the credit for discovering sweet potatoes on himself, saying that he also had the credit of a leader, if it weren't for his discernment and knowledge of the British at the beginning, maybe Xu Guangqi is still struggling with the imperial examination, how can he have spare time to cultivate sweet potatoes.

"Panic!"

Everyone immediately moved their eyes to Xu Guangqi's body, and the latter hurriedly arched his hand.

But Zhu Changluo didn't care and said.

"Merit should be rewarded and punished, this is a matter of course, do not hide from you Aiqing, this sweet potato is produced in Luzon, at the beginning of a businessman brought back from a foreign country, and then Xu Aiqing discovered, the first introduction, after I saw it, I was surprised by the yield of this thing, so I ordered Xu Aiqing to cultivate well, and now this sweet potato is already the fifth generation of good seeds, and the seeds introduced from Luzon at the beginning are very different!"

"Your Majesty means that this sweet potato still needs ...... Cultivate? ”

It was the second assistant boss who spoke, and he was born in a wealthy family, but he was not very familiar with farming, and then again, the word cultivation is still a little difficult to understand in this era.

When Zhu Changluo explained to Xu Guangqi at the beginning, it really took a lot of effort.

"Yes, Ge Lao Mingjian, this sweet potato is produced in Luzon, the yield in Luzon is extremely high, but it is not completely suitable for my Ming Dynasty, although the requirements for water and soil are not high, but after the introduction of the lower officials, there have been several times due to various reasons to make the sweet potatoes bitter, or the yield is reduced, fortunately, His Majesty pointed out, taught the officials to cross the cultivation method, from a large number of sweet potatoes to select the best breeding, and finally selected seedlings, a large number of breeding, and finally in the third generation of sweet potatoes when the cultivation was successful, the sweet potato ...... of today's taste was obtained."

Xu Guangqi arched his hand and explained.

His eyes flashed with excitement and fanaticism, and after he followed Zhu Changluo, he felt more and more that he was not wrong with following this lord, not only because Zhu Changluo had risen step by step, and now he had become the emperor, but also because of the endless ideas that emerged from this lord, whenever he encountered confusion, His Majesty could solve the problem with just a few words, and let his experiment go smoothly.

"But at that time, the yield of sweet potatoes was about 2,000 catties to 3,000 catties, and the officials worked hard to cultivate, and only then did they find good varieties among the fifth generation of seedlings.

I have to say that Xu Guangqi's theory is refreshing to a group of bigwigs, and it is the first time they have heard that this kind of person can still be cultivated and distinguished, but all the people present are smart people, and they quickly sorted out the logic from Xu Guangqi's slightly difficult words.

"What Lord Xu means is that this kind of seedling is also good and bad, passed down from generation to generation, and this acre of land is cultivated by Master Xu from the excellent seedlings selected from many seedlings?"

Soon, someone recreated Xu Guangqi's theory.

It made Xu Shaoqing stunned, he always felt that there was something wrong, but he couldn't say it, but Zhu Changluo shook his head secretly and said.

"In any case, if there is no hard work of Xu Aiqing, this thing will not only not become a good seed, but will become a harmful thing, I will be rewarded for meritorious service, from now on, I will promote Xu Aiqing to be the secretary of Sinong Temple, officially in charge of the affairs of Sinong Temple! What do you think? ”

What went wrong, of course Zhu Changluo was clear, the method he taught Xu Guangqi was actually very simple, and the principle was a Mendelian pea hybridization experiment that a middle school student in later generations knew.

And the principle of this experiment is also one of the methods of cultivating excellent grain in later generations, but Xu Guang uses cultivation, not only to select good seeds, but also to maintain excellent traits through various methods, and cultivate new varieties, but limited to the times, it is obvious that these ministers can only understand that from many seedlings to screen out excellent seedlings.

The difference can be described as a chasm, presumably even Xu Guangqi knows it but doesn't know why, and he doesn't know the difference.

After all, this new subject knowledge and inherent cognition are too different, and if they want to understand and accept it, I'm afraid it will take a while, Zhu Changluo secretly thought to himself, could it be that this is the so-called generation gap?
