Since Zhang Yanxi introduced potatoes in the live broadcast room, Liu Che and Wei Qing beside him have been in a state of shock, thinking that he got wheat with a yield of eight stones per mu, which is already an extra joy, but he didn't think that he could still meet potatoes with a yield of up to sixty-six stones per mu, how lucky is he? How fortunate it is?

Look carefully at this lump, is he ugly? It's not ugly at all, but it's too beautiful.

With such grain planted, why worry that the Huns will not be destroyed? Why worry about the world?

However, the next sentence of Miss Zhang made the hearts of these people who smoked potatoes rise to their throats.

"However, there are drawbacks to this potato."

"This potato needs to be cut into small pieces after germination, and the sprouted potatoes are poisonous, so the sprouted potatoes cannot be eaten, and the land on which the potatoes are planted cannot be used in the second year, including planting other high-quality vegetables, and you need to raise them for a year before you can grow other things."

Cao Cao and the others breathed a sigh of relief, fortunately, but they were scared to death, thinking that there were any drawbacks, there were not many dynasties, but there was a lot of land, the problem that this girl said was not a problem, but the sprouted potatoes could not be eaten, and this still had to be announced.

Qin Shi Huang looked at the discussion of this group of people, he was also shocked, seeing that there was another kind of rice seed in his hand, he was a little lost, why didn't he smoke potatoes, there is a yield of potatoes, why worry about him Daqin still eats grain with rice husks.

Zhang Yanxi answered a few more questions, and a few more drew soybeans, mung beans, and various other varieties of corn and wheat, and improved varieties of rice.

"Didn't you smoke hybrid rice?" Zhang Yanxi asked loudly, didn't her Uncle Yuan's hybrid rice appear in the blind box? Shouldn't it?

Qin Shi Huang, who was holding the rice seeds, and Zhu Yuanzhang, who was about to ask, were excited, could it be that the yield per mu of this rice is higher than that of potatoes?

Qin Shi Huang: Miss Zhang, I have this hybrid rice in my hand, I don't know the yield per mu?

"Congratulations to His Majesty the First Emperor, this hybrid rice is a rice variety that took several years to develop by Grandpa Yuan, the national treasure of our flower country."

"The so-called hybrid rice, is the selection of two genetically certain differences, at the same time their excellent traits can complement the rice varieties for hybridization, hybrid rice leaf area coefficient is larger than conventional rice, more ears, photosynthesis is stronger, the organic matter produced is naturally more, rice yield has been greatly improved."

"At the time of the world's population explosion, the research of hybrid rice has been successful, solving the problem of population famine and food shortage, feeding at least one-fifth of the world's population, which is a milestone in China's science and technology, and Grandpa Yuan himself is respected as the "father of hybridization". ”

Zhang Yanxi passionately introduced the significance of hybrid rice for future generations of flower growers, as a person who has made great contributions to the country, who can not worship it, and Zhang Yanxi's excitement is different, although the people of all dynasties listened excitedly, but also a little confused, Miss Qiao said that hybrid rice feeds at least one-fifth of the world's population, how many people are there?

Qin Shi Huang: Miss Zhang doesn't know how many people are one-fifth of what the country of flowers says?

When Zhang Yanxi heard this, he patted his brain: "Look at my memory, I forgot to tell you that there was no concept of the whole world in ancient times." ”

I saw Zhang Yanxi, turned on the computer, and found a map of the world earth, "This sphere is where we live now, we call it - the earth, the long river of history is mediated to the end of the Qing Dynasty, there is no emperor." ”

Qin Shi Huang: ......

Liu Che: ......

Kangxi: There is no emperor! What about my Daqing!

Zhu Yuanzhang: It seems that great changes have taken place in the last years of the Qing Dynasty, but without an emperor, wouldn't the country be in chaos?

"Since the end of the Qing Dynasty, there have indeed been too many wars in later generations, and our country has also buried many ancestors and heroes, the process is too tragic, and we will tell you in the later period, a hundred years of war to have the current flower country and these more than 200 countries on the earth."

"To where we live now, there is no emperor."

"Our country has a land area of only 9.3 million kilometers, and the ocean area is as much as 4.3 million square kilometers, but the area of the flower country is not the largest, the largest is Russia's land area of about 1,703 square kilometers, these countries combined, almost more than 8 billion people, one-fifth of the population is almost 1.6 billion."

This hybrid rice, terrifying, Qin Shi Huang took a deep breath, the people of later generations have actually reached such a multiplicity level, and they are worthy of being the descendants of my Great Qin Kingdom.

Liu Che: My real name is envious!

Li Shimin: Why didn't I get it?

Cao Cao: The potatoes in my hand are a little unfragrant.

They were amazed at the sheer population of the country in later generations, and the hybrid rice that could feed billions of people, and they were shocked that the people of later generations had such talent and strength to such a degree.

Zhao Kuangyin beat his chest angrily, in vain I am so rich in the Song Dynasty, and I robbed so many blind boxes, but none of them are hybrid rice.

"Good, good, good!" The First Emperor was pleasantly surprised and said three times in a row, just now he was still disappointed to grab just a rice seed, and now he just wants to dance a sword happily, saying that our First Emperor His Majesty picked up the sword and danced outside the palace, telling about happiness.

Zhu Yuanzhang is not afraid of too much, "Come here, summon the ministers to meet, and hold a banquet tonight to celebrate my Daming this divine seed." ”

"Hybrid rice is most suitable for planting in places with sufficient sunshine and precipitation, that is, the most suitable area in the south, if it is planted in the north, the yield is lower, and one crop a year, but if it is planted in the south, not only the yield per mu will be higher, but also can reach two crops a year, or even three cropping."

This news is a great shock to the emperor in front of you, who doesn't like to eat rice? But they didn't get it, so they could only look at the barrage sent by Qin Shi Huang with jealous eyes.

Liu Xiu, who has never spoken until now, looked at the hybrid rice seeds on the table in his palace, his eyes lit up, the yield per mu is so high, if it is planted in the south, it may reach two or even three crops a year! Liu Xiu touched his chin and looked at the seeds of the rice seed and kept smirking.

Liu Xiu: Haha! I got it! I got it!

Zhu Yuanzhang: ......

Zhu Di: This person's luck is indeed not comparable to ordinary people.

"However, there is one point, this hybrid rice seed cannot be retained, because it is a hybrid of two high-quality rice, and the quality of the next generation of seeds will be reduced a lot, and it may not be as high as the yield of ordinary rice seeds, and this hybrid rice can only be cultivated every year."

"Although you can't keep seeds, this kind of season can also compare the yield of all dynasties, and the dynasties that hope to get seeds will plant well."
