Following.

Li Chengqian got up early in the morning to wash, and under the service of the palace maids, he put on the prince's clothes, wore a hood on his head, and tied a jade belt around his waist.

"Has the King of Jin ever risen?" Li Chengqian asked.

"Lang Jun! His Royal Highness the King of Jin had already gotten up early in the morning, and now he should have arrived outside the Xiande Hall to wait for the court. Wang Quan said.

This was the first time that Li Chengqian summoned hundreds of officials after returning to Chang'an.

When the crown prince was in charge of the country, the officials of the East Palace were the officials who handled the national government affairs, and the official document format of the prince's system was used to issue documents to the whole country.

Therefore, the crown prince did not summon his ministers in any of the palaces of Ouchi, but discussed state affairs in the Hall of Wisdom in the East Palace.

The place where all the officials went to court was changed from the original Taiji Hall to the Xiande Hall of the East Palace.

Of course, the crown prince is not an emperor after all, so it is naturally impossible to go to court every day, except for major events, there is no need to go to court at all at other times.

Li Chengqian had just returned to Chang'an last night, and the hundred officials naturally wanted to go to the Xiande Hall to go to the court and report to the crown prince on political affairs.

The hundred officials went to the Xiande Hall early in the morning to wait for the arrival of the prince.

"His Royal Highness the Crown Prince has arrived!" Wang Quan's shrill voice came from outside the hall, and the hundred officials hurriedly stood up according to the size of their ranks.

Li Chengqian was supported by Wang Quan and went to the seat that belonged to him to do a good job, and the hundred officials saluted.

"I've seen His Royal Highness the Crown Prince!"

"All the ministers are exempt!" Li Chengqian said.

"Your Highness!" The hundred officials got up and knelt on the mat.

After the hundred officials were seated, Li Chengqian nodded at Wang Quan, and Wang Quan stepped forward, holding Li Er's edict with both hands and began to read it.

"Emperor Tang Dynasty Order: Worship the King of Jin as the right concubine of the East Palace."

Such a personnel appointment must not only be read out in Luoyang, but must also be read again in Chang'an, so that the officials in Chang'an will know about this appointment.

"The widow just returned to Beijing last night! I don't know if you have something important to play? After Wang Quan finished reading, Li Chengqian said.

Now that the Tang Dynasty is at its peak and the society is stable, there are no major matters, and small matters are handled by the original three provinces and six ministries and transferred to the subordinate official system of the East Palace.

You don't need to talk about it at all.

"The minister has the right to play." The peasant officer stood up and went out of the line and saluted.

"What did you do?" Li Chengqian asked.

But I was secretly conjecturing in my heart, could it be that the research on hybrid rice has a result?

Just as Li Chengqian thought, the research on hybrid rice has already yielded preliminary results.

The study of hybrid rice has always been one of Li Chengqian's greatest concerns.

If hybrid rice can be successfully researched, it will be an epoch-making feat and will drive the agricultural development of the entire Tang Dynasty.

Completely solve the population and food problems of Datang.

In this way, there will be no increase in population after the Wu Zhou Dynasty, coupled with land annexation, so that the people have no land to cultivate, and there will be a phenomenon of fleeing.

As long as the problem of food is solved, the problems caused by population growth can be solved.

Moreover, the increase in grain production can also lead to economic development, and the increase in grain production solves the problem of population growth.

"Your Highness! After the hard work of the minister and several colleagues, the hybrid rice mentioned by His Highness has been somewhat effective. "Nongguan said.

"Oh!" Li Chengqian was overjoyed when he heard this: "I don't know how this output is? How much can yield be increased per mu? ”

Everything else is false, and only an increase in production is real, and if they are allowed to blow the sky, it is not as good as an increase in grain production.

How much food can be added determines how many people can be fed.

"Except for the barren land, the yield per mu in the upper field increased by three buckets on the original basis, and the yield in the middle field increased by one bucket per mu."

"This is just the experimental stage, and if the thorough research is successful, the minister estimates that the yield of Ueda can increase by more than one stone per mu, the yield of Zhongtian can increase by one stone, and the yield of barren land can also increase by about four or five buckets." Nongguan Road.

Don't underestimate the increase in yield per mu, the increase in output across the country adds up to a large amount.

The increase in yield after the success of the study is still a conservative estimate, and it may even exceed the conservative value.

This means that there is no need to worry about population growth without increasing the amount of land.

In addition to agriculture, these people can also be engaged in various industries such as handicrafts.

With the development of agriculture, the population has grown, and then the population has grown to the development of handicrafts and other industries.

The improvement of people's living standards, the increase in the consumption level of the people, and the sustainable growth of the economy of the entire empire.

This is a grand blueprint, and we need to work together to achieve this grand blueprint.

Therefore, the first step is to increase grain production, and only when the problem of food and clothing for the people is solved will the people have spare time to do other things.

The increase in food production will also ensure that the national army can respond to foreign invasions and disaster years.

"How long will it take you to successfully research hybrid rice?" Li Chengqian asked.

Once the research on hybrid rice was successful, he was able to issue a decree in his capacity as the prince of the prison state, and vigorously promote it in areas of the country where rice could be grown.

Hybrid rice not only increases yields, but also has higher disease resistance, and all kinds of comprehensive shapes are higher than non-hybrid rice.

"Your Highness! We already have experience, but we will not be able to study it until the second crop is planted at the earliest. "Nongguan said.

"In other words, it will not be possible to sow hybrid rice during the spring planting period next year!" Li Chengqian said.

He also thought that he could plant the first batch of hybrid rice when he ploughed next spring, but he still couldn't do it.

"Yes, Your Highness! Our research on hybrid rice is still immature, and there are still many flaws, even if it is forcibly planted, let alone increase the yield at that time, it may lead to no harvest due to poor operation. "Nongguan said.

"Alright! Since it is not possible to promote this technology at the time of spring ploughing, it is a pity! But it's nothing, you must research hybrid rice as soon as possible to benefit the people of my Datang. Li Chengqian said.

"It's Your Highness!" The peasant official said: "Your Highness! This is the record and data of our research on hybrid rice, as well as the direction of our research on hybrid rice, etc., and I would like to ask Your Highness to take a look. ”

After the farmer finished speaking, he took out a small notebook, which recorded his scientific research achievements during this period.

Wang Quan hurriedly stepped forward, took the small notebook in the peasant official's hand, turned around and returned to Li Chengqian's side, and put the notebook in front of Li Chengqian.

Li Chengqian took it, looked at it for a while, and said: "This hybrid rice matter, in the future, I will leave it all to you, from now on, you only need to do one thing for the widow, that is, to study this hybrid rice, and you won't bother with other trivial matters." ”

"No!" Nongguan Road.

Li Chengqian closed the notebook, handed it to Wang Quan, and asked him to pass it on to the peasant official.

"Are there still people in the princes, do you want to do something?" Li Chengqian asked.

"The minister has nothing to do." Everyone said in unison.

"So, let's all disperse!" After Li Chengqian said that, Wang Quan hurriedly stepped forward to help Li Chengqian up.

At the minister's greeting voice, he left the Hall of Virtue.
