Eating can relieve a person's nervousness.

Li Shimin reached out and took a piece of candy and put it in his mouth. Fang Xuanling and Gao Jingming saw Li Shimin doing this, and they also took it and put it in their mouths.

"Hmm", it feels good.

The level of agricultural science and technology in Datang is very low, and the grain output is also very low. The main base of Datang is the Shaanxi area. The main food crops are wheat and millet. The yield of wheat is about 250 catties per mu in watered fields and about 120 catties in dry fields. Millet is completely dependent on the sky for food, and the yield per mu does not exceed 100 catties.

The situation is similar in other provinces. Jiangnan is a little better, but there are not many places to develop, and the main grain producing area is only Yangzhou.

At this time, the population of the Tang Dynasty was only about 18 million people, and the land area was vast, so such a low grain production could maintain normal consumption in the absence of natural disasters.

"Everything has its own inherent regularity, and the same is true for the growth of wheat. Now wheat planting, from the depth of cultivated land, planting time, field management have room for improvement, as long as the method is appropriate, the yield per mu reaches 450 catties, there is no problem at all. ”

In 2014, Xianyang 10,000 mu of high-yield demonstration plots were 1,243 kilograms, including a high-yield experimental field, with an average yield of 1,428 kilograms per mu. Eight districts and counties in Xi'an have implemented high-yield wheat production, with an average yield of more than 1,200 kg per mu.

To be on the safe side, Li You only gave one-third of the yield per mu.

Li Shimin asked: "Do you know this new planting method?" ”

Li You said with a smile: "Erchen can't do anything else, he only knows how to eat, everything related to eating, Erchen is clear." ”

Fang Xuanling said excitedly: "This is great, this is double the current output." If such an output can really be achieved, Datang will no longer worry about food. ”

"Yes, Your Majesty. For Datang, this is auspicious. Gao Jingming was also extremely excited.

Li Shimin asked: "Wheat can increase production, but what about other crops?" ”

Li You said: "The yield of grain per mu is more than 300 catties. ”

There is a basis for this production of his. The yield of millet of general varieties is 600-800 catties, and the rice yield is 70%-75%. However, with the development of science and technology, all kinds of hybrid millet have come out one after another, and the yield per mu is also growing rapidly, such as: on a test field in the lower garden of Zhangjiakou City, the highest yield per mu of "Zhangzagu No. 5" has reached 1720 catties, creating a world record.

When calculating the yield of millet, Li You fully considered the irrigation conditions, chemical fertilizers, pesticides and other factors, as well as the scientific planting methods that he could search, and gave extremely conservative values.

Li You originally wanted to say that he could grow rice in Guanzhong, but after thinking about it, forget it, more is better than less.

In this way, Li Shimin and others were also very excited.

At this time, small noodles and millet were the main crops in the northern region, and the increase in the output of these two crops was equivalent to the overall increase in the grain output of the entire northern part of Datang. The corresponding agricultural tax revenue will also be greatly increased.

Li Shimin stood up excitedly, took a few steps forward, stopped and said, "Okay, if this is the case, it will be really auspicious from the sky, and Datang will not have to worry about it." ”

Li You said: "Father, if you agree to the conditions of the son, the son is willing to leave immediately to go to Qizhou for trial planting, and then promote it to the whole country." ”

Li Shimin was in excitement, and he didn't hear what Li You said at all. He said: "Immediately organize people to try planting in Wannian County, and then promote it to the whole country." ”

Li You said: "Father, the incident that the son said ...... the minister"

Li Shimin interrupted him and said, "Li You, the king of Qi, listens to the order, you immediately write out the relevant materials and hand them over to the household department, which is responsible for research and promotion." ”

Li You was helpless and said, "Erchen obeys the order." ”

Then, he asked, "Father, what do you do about what you promised your son?" ”

Li Shimin looked at Li You and admired it very much, he felt more and more that this child was a good seedling, as long as he was strictly disciplined, he would definitely be able to become a talent.

He said solemnly: "Qi King Li You, you are very talented, but your lazy temperament must be disciplined. Don't talk about it anymore. ”

"Damn, this dad is too unreasonable!" Li You was also anxious, and he said, "Father, why are you unreasonable? What a golden mouth, it's just a Buddha ......" he almost said the words that followed.

Li You wanted to cry without tears, and left the Liangyi Hall with a grin.

After Li You left, Gao Jingming said: "Your Majesty, the minister has a suggestion, the minister is not familiar with the matter of increasing grain production, can you let His Royal Highness King Qi stay in Chang'an for the time being and preside over this matter." ”

Fang Xuanling also said: "Yes, Your Majesty, this matter is related to the strength of the Tang Dynasty, and the stakes are very high. There are also follow-up matters for disaster relief, all of which require His Royal Highness King Qi to stay in Chang'an, and the minister agrees with Lord Gao's opinion. ”

Li Shimin hesitated, Li You's departure from Chang'an was a matter that had already been decided, if he didn't leave Chang'an, it would be difficult for Li Ke and Li Tai to leave Chang'an in the next step.

However, this food matter, as well as peanuts and sugar beets, ordinary people really can't handle it.

Li Shimin weighed the pros and cons and said: "Okay, the king of Qi will stay in Chang'an for the time being, and when he grows high-yield grain, he can go to Qizhou to take up his post." ”

Yiyang Palace.

The green-headed fly Quan Wanji is finally here.

On this day, after the early dynasty, Quan Wanji went to the Ministry of Officials to complete the formalities and went to report to the Yiyang Palace.

When he came to the gate of Yiyang Palace, Quan Wanji felt a little uncomfortable. Before he came, he had already sent his relatives to inform the people of the Yiyang Palace, and they should greet them in front of the gate, but it was deserted in front of the gate, except for the soldiers standing guard at the door, there was no figure.

Seeing him coming, his personal entourage Quan Xiaonian came over with a bitter face and said, "My lord." ”

Quan Wanji asked, "Didn't you ask you to inform Huang Changshi?" ”

Quan Xiaonian said: "People don't let me in. ”

"Bastard, what a gut!" Kwon Wanji was furious. You must know that he is the supreme administrator of the Qi Palace, and these guards at the gate are all his subordinates, and they dare to neglect their personal entourage like this, they are simply about to rebel.

Quan Wanji came to the doorman and shouted, "Open the door." ”

The doorman was expressionless and said, "Who is the adult?" Please show your official certificate. ”

Quan Xiaonian took advantage of the power and shouted: "Bold, this lord is the new chief Shi Quan of the Qi Palace, don't open the door quickly!" ”

The doorman still said indifferently, "Please show your official certificate." ”

Quan Wanji was helpless, took out the official disc from his arms and handed it to the doorman.

The doorman took it and looked left and right, but he didn't say anything.

Quan Xiaonian shouted: "After reading it, don't hurry up and open the door." ”

The doorman said, "Wait a minute, the villain is illiterate, and he has to show us the captain." ”
