"Chengqian, who do you think should be sent to warn Goguryeo?" Li Er asked.

For Li Er, it doesn't matter who he sends, no matter whether he succeeds in the end or not, Li Er will send troops to Goguryeo, give Goguryeo a little color and see, since this matter was proposed by the prince, let the prince pick someone to choose.

Lee Seung-gan thought of the Sangri Hyun Award, and it was he who sent an envoy to Goguryeo to warn Goguryeo not to be too arrogant and stop attacking Baekje.

At that time, Li Chengqian never understood that the Tang Dynasty was full of talents, and it was not good for Li Er to send anyone in history, so why he had to send Xiangli Xuan, an official of the grain management department, to Goguryeo.

Even if Goguryeo is just a small country, if you only send a grain administrator, you will inevitably ignore Goguryeo.

What's more, the matter of the envoy should generally be the matter of the host and guest department of the Ministry of Rites, and it has a half-dime relationship with the Xiangli Xuan Award.

Indeed, the current Li Er doesn't take Goguryeo too seriously, and being able to send an official to say hello to Goguryeo is already considered benevolent and righteous.

If it weren't for the crown prince's proposal, Li Er wouldn't have bothered to pay attention to Goguryeo, a small country with a small projectile, and dare to provoke the majesty of the Celestial Empire! It's like looking for death.

"Father! Erchen thinks that the Prime Minister Li Xuan Award is suitable! can take on the heavy responsibility of sending Goguryeo! Li Chengqian said.

"So be it! Let the prime minister of Sinong Temple, Li Xuan, hold the talisman festival and send it to Goguryeo. Li Er nodded in agreement with Li Chengqian's opinion! On the spot, it was announced that Sangri Hyun would be awarded to Goguryeo.

Li Er said that, without giving Chu Suiliang a chance to speak, he left the main hall directly and went to the side hall, and Li Chengqian had no choice but to go back to his East Palace when he saw this.

"Wang Quan, send someone to Sinong Temple to call the two peasant officials from before to the widow." Li Chengqian said.

"No! Slaves and maids, let people go and call them! Wang Quan took the order and left.

As soon as Li Chengqian returned to the East Palace, he had the officials in charge of agriculture called, with whom he had mentioned research on hybrid rice a few months earlier.

Let them go back and work in the direction he said, and see if they can come up with hybrid rice.

The Tang Dynasty is fighting everywhere, and this food consumption is a huge problem, if there is a disaster year, there is not enough food at all.

The grain production of the Tang Dynasty was not large, and only one acre of good land could produce 2 stone of grain when the year was good.

The Tang Dynasty yielded 3.8 stones per mu and 3.8 stones, and one stone was equivalent to 100 catties in the Han Dynasty, and the Tang Dynasty was 3.8 times that of the Han Dynasty, that is to say, the best fertile land could produce more than 700 catties of grain at most.

This is still when there is a good year, there will be such a harvest, if the year is not good, it will be enough.

The Tang Dynasty was different from later generations, one mu of fertile land could produce hundreds of catties of grain, or even more than a thousand catties.

How to increase grain output has become an issue for Li Chengqian to consider.

So Li Chengqian thought of this hybrid rice that could improve the yield and quality of crops.

If hybrid rice can be developed, it will be able to greatly increase the grain production, and the people's families will be able to accumulate more grain.

When the time comes, if you really encounter a famine or something, you don't have to worry about food.

However, it is not an easy task to study hybrid rice, and even if there is technical information on hybrid rice in Li Chengqian's later generations, it must be studied by agricultural officials in the Tang Dynasty.

It's a huge project too!

Soon, the chamberlain of the East Palace recruited the two peasant officials to the East Palace.

"See Your Highness!" Two peasant officials, one tall and one short, one fat and one thin, saluted Li Chengqian.

"Excuse me! Wang Quan gives the seat! Looking at the two agricultural officials who came in, Li Chengqian said, and instructed Wang Quan to give him a seat.

"Thank you, Your Highness!" Wang Quan ordered two chairs to be brought to the two peasant officials.

"How's the progress of the hybrid rice that the widow asked you to make?" As soon as their buttocks touched the chairs, Li Chengqian couldn't wait to ask.

The two agricultural officials felt a little embarrassed, and the prince gave them the technique of cultivating new rice called two-line hybrid rice, and they carefully studied this technical work during this time, and also studied it according to the above technology.

Rice is a self-pollinating plant, and the stamens are born in the same flower because the flower is small and each flower bears only one seed.

It is very difficult to breed new varieties by means of artificial pollination.

There are not many rice plants in the Guanzhong area, and there are too few people who can conduct research and cultivate new varieties.

So far, there is still no substantive breakthrough in their research, but they have also learned some experience.

With a little more time, it shouldn't be a difficult problem to come up with hybrid rice.

"Your Highness! We have studied rice in accordance with the technical works given by His Highness and the guidance of His Highness, and so far, there has been no substantial breakthrough. The tall and fat farmer said.

"Yes! Your Highness! We selected a batch of rice for experiments, all of which ended in failure, and we have summed up some experience, and when the spring comes, we will conduct another experiment. "Thin and short farmer said.

"Why did it fail? But what's wrong with the information I gave you? Li Chengqian said.

"Not really! His Royal Highness's agricultural writings have opened us up to a whole new world, except that rice is a self-pollinating plant, and the stamens grow in the same spikelet, and the spikelet is relatively small, and it is difficult to pollinate it artificially! The short farmer said.

Then he said a lot of things related to this aspect, and Li Chengqian was in a fog when he listened, he didn't have any research on this aspect, and he didn't know many academic issues.

"I'll leave the matter of hybrid rice to you, I don't know much about this aspect, and I can't give you substantive advice, so I can only rely on your own slow exploration."

"Once such hybrid rice can be developed, it will be able to increase the grain massively, which is a great event for the benefit of the country and the people."

"If only you could succeed in your research! That is a feat for the benefit of the people, and you will be forever recorded in the annals of history! Forever! Revered by all ages! Li Chengqian said.

Li Chengqian felt that he was too anxious, where is such a hybrid technique so easy to complete.

If no one wants to complete it for two or three years, how can he, a layman, guide these insiders.

It is impossible to increase rice yields at the moment, after all, hybrid rice technology is not yet mature.

After hearing this, the two of them naturally felt enthusiastic in their hearts, and who wouldn't want to be able to go down in history.

"Your Highness, rest assured! We are duty-bound to do such a thing that benefits the country and the people! It's just that it will take some time, and in time, we will be able to develop hybrid rice. The tall farmer said.

"Good! The widow waits for news from you. That's all for today, go back first! Li Chengqian said.

"No!" The two peasant officials got up and said goodbye: "The minister retires!" ”
