People in Datang have been expelled from school

Chapter 1129 General knowledge

The next day Li Zhi took a group of academy children to survey and map the terrain of the surrounding map, including the fields.

According to the arrangement, no matter how the trees are planted, they will not affect the fields.

There are not many paddy fields around Chang'an, but many of them are dry land and wasteland.

Most of the paddy fields are along various river channels.

The so-called eight waters surround Chang'an, and food is grown near the rivers around Chang'an.

Li Shimin sat in the Ganlu Hall, listening to Wang Ding's report.

The news was all sent from Goguryeo, and it also talked about the current situation in Goguryeo.

Li Shimin rubbed his temples wearily and said, "So my truce is useless?"

Wang Ding said in a low voice: "The new Goguryeo king has just ascended the throne not long ago, and now he needs a big battle to establish his prestige and win people's hearts."

Li Shimin sighed and said, "It's really like this."

Wang Ding said in a low voice: "At present, it seems that the war between Goguryeo and Wa is still going to be fought. In the coming year, the envoys of Goguryeo and Wa will come to Chang'an together."

Li Shimin nodded and said, "Let the Ministry of Rites take care of the affairs of Wa and Goguryeo."

Wang Ding said again: "Your Majesty, His Royal Highness King Jin is leading people to survey and map the land, and Princess Gaoyang's main household department has produced the field files to check the fields before planting trees."

Li Shimin looked at the memorial with a blank expression and said: "Lizhi is also out of filial piety, telling the Ministry of Households what to do or what to do."

Wang Ding bowed and said, "This old slave understands."

Walking out of the Ganlu Hall, Wang Ding let out a long breath, and His Majesty said what should be done to the household department.

Naturally, Hubu's field records cannot be shown casually for others to see.

This is what His Majesty said the Ministry of Households should do.

But His Majesty said again that it was all out of filial piety.

It is also a beating to the Ministry of Finance.

Wang Ding came to the household department, and the household department is in a mess at the moment, obviously Princess Gaoyang just came here to make trouble.

Several officials from the Ministry of Households were tidying up bitterly, and when they saw Wang Ding coming, they asked, "What does Your Majesty say?"

Wang Ding said: "Your Majesty said what the household department should do or what to do."

All the officials of the household department nodded, how could the field records be easily shown to others.

Wang Ding said with a sad face: "Speaking of it, it is also out of filial piety. The princes and princesses are sensible and want to plant trees for the eldest grandson queen, and it is also out of filial piety."

While talking about Wang Ding looking at everyone's faces, Wang Ding said: "Princess Changle, His Highness King Jin, Princess Gaoyang, Princess Jinyang, His Highness King Wei, and His Highness King Shu all want to be filial, and they are all good children. what."

The official from the Ministry of Household Affairs, whose face had softened just now, fell silent again.

If the household department handed over the field records, would it offend the three princesses and the three princes?
Although there are His Majesty's words now, who would dare to offend the six royal heirs all at once.

Are you going to hang out in the future?
Wang Ding said slowly: "Although filial piety is the reason, you still have to do your job well. Your Majesty will see it, and I will bring the old slave's words."

After Wang Ding left, it was the turn of a group of officials from the household department to get entangled.

If the field record is not handed in, the three princesses and the three princes will be offended, and it will be difficult for the Ministry of Household Affairs in the future.

But if out of filial piety, the account book of the farmland mu was handed over to Jingyang, it was also because of the filial piety of the princes and princesses.

Maybe His Majesty will not care about the beauty of adults because of the filial piety of the princes and princesses, even if he cares about it, maybe he can make Princess Gaoyang plead for mercy.

Besides, the empress is also happy to have this kind of filial piety, and His Majesty will not care too much if she thinks about it.

Several household officials were sweating profusely, discussing one after another.

If you don't hand over the field records, I'm afraid the current queen will be unhappy.

Although the imperial court ruled that the field records and files should not be read casually to others, and the queen is also a person who knows the general situation, but she feels a little bit unhappy if she doesn't say it.

After weighing the pros and cons, everyone in the Ministry of Households still took out the field records of more than ten miles around Chang'an, and hurriedly sent them to Jingyang.

After three days of surveying and mapping, Li Zhi and a group of college students also made a design plan.

There was a sand table in front of Li Zheng. Various buildings were placed on the sand table. The largest one was Chang'an City, and the other scattered ones were the villages and counties around Chang'an.

Li Zhi said: "The situation in the ten miles around Chang'an is here. The household department also sent the field records and files over the past two days, and this sand table has been completed."

The green lines drawn on the sand table are the green belts envisaged in the first step.

Li Zhi continued: "We made a preliminary estimate. It takes [-] trees to plant the first step around Chang'an, and they can't be too close to the city wall, otherwise it will affect the city defense. Neither the army nor the court will agree. of."

Li Zheng looked around Chang'an City and said, "How's the soil outside Chang'an City?"

Li Zhi said: "Most desertification is quite serious, with too much soil erosion."

It seems that greening outside Chang'an City is a very serious problem.

Li Zheng said: "We can plant some more drought-tolerant shrubs around Chang'an City, and then spread a layer of turf to turn Chang'an City into a grassland, which can reduce the harm of wind and sand."

Li Zhi held the booklet in his hand, which was filled with various notes, and said in a low voice, "But even if it's just planting trees around Chang'an, it's not a cure for the symptoms."

Seeing Li Zhi's expression, Li Zheng said, "You thought about it too?"

Li Zhi said: "Actually, the biggest wind and sand damage comes from the west of Longyou. The previous generations lived in troubled times, and everything was food. They looked at the forest and turned the forest into fields, and finally the fields became fields. The desert, that’s why this is happening now.”

After a pause, Li Zhi said in a low voice, "Teacher, it must be like this."

What Li Zhi said was actually right.

And what Li Zhi sees is even more terrible. If you want to do greening for a long time, you need a stable era.

Afforestation cannot be completed in one or two years, and may even take more than ten years.

How big the variables will be in the past ten years.

Furthermore, the greening will continue for more than ten years, or even a hundred years later.

People live in the present, how many people will think about hundreds of years later.

Li Zhi added: "In addition to planting trees around Chang'an, I think it is more important to plant a huge sand prevention forest in the Longyou area to the west of Chang'an, so that most of the wind and sand can be blocked, and the scale is even tens of thousands. Thousands of trees."

Li Zheng shook his fan and nodded.

Lowering his head somewhat disappointed, Li Zhi said: "Tens of thousands of trees is not easy, it requires a lot of manpower and material resources, and it will take many years to complete."

Slowly raising his head, Li Zhi said, "Teacher, can we do this?"

Li Zheng took a sip of tea and said, "Has His Royal Highness Jin heard the story of Yugong Yishan?"

Li Zhi nodded and said, "I have heard."

Li Zheng also said: "In fact, there are also stories about Jingwei's reclamation of the sea. These stories are deeply rooted in the hearts of the people. In fact, we have the spirit of Yugong Yishan in our bones."
