Li Shimin's will: Li Zhi, the throne belongs to your brother

Li Shimin picked up the paper, squinted his eyes and said.

"With the addition of these, the meaning of the words is clear and concise, and the complexity is simplified.

How wonderful!

If this comes from Confucianism, how can it be called a great Confucianism. "

With that said, Li Shimin passed the paper to the important officials behind Li Tai.

Soon, the papers from Li Tai were passed on one by one, and everyone praised them one after another.

"Such methods should be called Great Confucianism."

"It's just that the word is too small, why do I feel a little dizzy and can't read the words clearly?"

"Sentence reading and sentence segmentation, in this way, it is really unheard of."

"Numbered page numbers, eliminating the need for several pages, are also fun."

Everyone was admiring, only Wei Zheng was sighing, he felt that he couldn't give Li Tai any knowledge.

Soon, everyone rewrote a word according to Li Tai's method, and wrote their own signatures by the way.

Symbolic things have been done.

Next, this dictionary will be handed over to a group of people to perfect it.

It will take a while, and it will require an overseer.

"How about handing over the matter of compiling the dictionary to King Wei's teacher?"

Although Li Shimin was asking a question, he had a positive tone.

Glancing at everyone, no one objected, so he confirmed the final result and said: "I will leave this matter to Aiqing."

"I will do my best." Wei Zheng hurriedly saluted.

"Well, if there is nothing else, let's go!"

After Li Shimin finished speaking, his eyes signaled Li Tai to stay.

"I'm waiting to leave!" Everyone started to stand up one after another, saluted Li Shimin, and then left towards the door.

All of them were preoccupied, and walked quickly towards the home.

What happened today, they had to figure out what Li Shimin meant.

Li Tai deliberately waited until the last one, and walked out with Li Shimin.

Li Shimin asked straight to the point: "Why didn't the Emperor mention this to me about educating the barbarians?"

"I don't think so..." Li Tai also only thought that pinyin and newspapers could play a role in guiding people's hearts.

I really didn't expect that pinyin plus Buddhist scriptures are used to brainwash.

"..." Li Shimin was silent for a while, and then spoke again.

"A few days ago, Huang'er made the cement dry, and after it dries, it is no different from that stone.

I have tried many times, as long as I follow the method, anyone can turn mud into stone. "

Listening to the words 'turn mud into stone', Li Tai explained in a very speechless manner.

"That's nature, but it's not 'turning mud into stone', it's chemistry in science."

"I understand, the emperor said last time that science is too amazing."

Li Shimin asked with a sigh.

"By the way, does the emperor know how to farm scientifically?"

"I understand a little bit." Li Tai thought for a while and replied.

"Tell me." Li Shimin raised his eyebrows and said.

"At present, the Tang Dynasty is divided into north and south, all of which grow crops for one season.

But in fact, the south is warm and has plenty of rain. You can try to plant two crops to achieve two crops a year. "

Li Tai thought for a while and replied.

"Which two seasons of crops? Isn't this field barren?" Li Shimin said with wide-eyed eyes.

"Rice is planted in spring and harvested in summer, and then late rice is planted in summer, and winter wheat is planted in autumn.

Combining farming and animal husbandry, manure can be used to make fertilizer if the land is barren.

Regarding this matter, Erchen should go back and write things down! "

Li Tai thought for a while and said.

"Well, it's okay, this matter should be done as soon as possible, and spring plowing is a big deal."

Li Shimin could only nod his head, there was no rush for such a big event.

In the south where the climate is relatively humid and warm, Quyuan plow plus drum car plus fertilizer retting, and the combination of agriculture, animal husbandry, fishery and forestry.

A good climate, rich water system, tools, and the use of fertilizers should be able to meet the conditions for two crops a year.

In addition, the Grand Canal was built in successive dynasties.

You can directly start from Chang'an and follow the Guangtong Canal to enter the Yellow River to Luoyang.

From Luoyang, there is Tongji Canal, which reaches Huai River, and Huai River has Hangou, which can enter the Yangtze River.

The Yangtze River has the Jiangnan River, which can directly lead to Yuhang and enter the Qiantang River.

This water system runs from north to south, from the Jiangnan area in the south to Zhuijun in the north.

In the military, economically, and politically, it has a very high status.

Li Tai thought that with the help of the Grand Canal, he could reach the Yangtze River.

This is the land of fish and rice, the Yangtze River Delta, and the plains in the middle and lower reaches of the Yangtze River. These are two big granaries!

Controlling here, it can be said that there is basically no need to worry about food shortages.

Here, two crops a year are implemented, the combination of farming and animal husbandry is promoted, and manure is made, so that a large amount of grain can be quickly obtained.

This plan is feasible! !

In fact, spring wheat takes longer to mature as the climate cools.

Coupled with the war in the north, it was greatly affected, but the south was not affected much, which made it difficult to shift the economic center of gravity.

This is why Emperor Sui Yang continued to build the Grand Canal.

The appearance of farm tools such as Quyuan plow and drum car, and the role of beans in fertilizers were determined.

At the end of the Tang Dynasty, the south gradually began to have two crops a year, that is, rice was planted, and after the rice was mature and harvested, winter wheat was planted.

To maximize the role of the land, fertilizers are extra important at this time.

In ancient times, there were fertilizers. It is recorded in "Qi Min Yao Shu" that plant ash, bones, manure, and adzuki beans can be mixed as fertilizer.

This is very scientific. Plant ash mainly contains potassium fertilizer, bones contain phosphorus and calcium fertilizer, manure contains organic fertilizer and urea, and beans contain nitrogen fertilizer.

However, the plant ash produced by burning is very wasteful, and there are insects and bacteria in the feces.

It has to be further fermented and retting, which can kill insect eggs, bacteria, etc., so as to maximize the effect of fertilizer.

Thinking of this, Li Tai felt that he should read "Qi Min Yao Shu" and "Nong Shu" more when he went back to work as a supervisor of the blast furnace, so as to avoid any trouble.

"nine on nine..."

Back home, Li Taizheng looked at Wu Meiniang and Yan Wan in amazement.

Wu Meiniang held an abacus and taught Yan Wan how to make the abacus by reciting formulas in her mouth.

Seeing Li Tai coming back, the two put away their abacus in a panic, hid behind them and saluted.

"Husband, when did you come back?"

"Just came back, what are you doing?" Li Tai was speechless watching the two's small movements.

What are you hiding, the sound of the beads is 'da da' straight.

Seeing that Li Tai found out, the two exchanged glances.

Wu Meiniang simply took out a wooden abacus and said.

"It's okay to come first, Mei Niang is teaching my sister how to abacus."

Yan Wan quickly defended Wu Meiniang and said, "This abacus is what Wan'er wants to learn."

Li Tai took the abacus and flicked it a few times, the abacus bounced very well.

The Tang Dynasty was prosperous, and it was agreed that the abacus appeared at this time, but there is no evidence, only the Song Dynasty unearthed the abacus.

"Why does Wan'er want to learn the abacus?" Li Tai looked at the abacus and said.

A little hesitation appeared on Yan Wan's face, and her voice was a little low.

"My sister's family is strong, and she can help your husband a lot.

The concubine is a regular wife, but she is inferior to her younger sister in everything....

Wan'er also wants to help a group of husbands. "

As he spoke, he lowered his head and held the abacus firmly with both hands.

"Husband won't be angry?"

It turned out that the feelings were stimulated by Wu Meiniang.

Li Tai immediately understood what Yan Wan was thinking, and couldn't help laughing.

"Don't be angry, it's a good thing, but has Wan'er learned it?"

Seeing that Li Tai was not angry, Yan Wan quickly raised her head to show off.

"Of course I learned it. My sister praised me just now, saying that I can be the shopkeeper of that rice shop."

"Oh~ is it?"

Yan Wan raised her small face and spoke confidently and slowly.

"Of course, if your husband doesn't believe it, you can test your concubine status."

"it is good!"

Li Tai looked at her confident smile and said casually:

"An old man took the money to buy meat, and the meat cost six cents a catty, and if he bought it all, he would have a penny left over.

The old man thought it was expensive, so he left, and saw another shop, which said seven cents a catty, and if he bought them all, he would lose one penny.

Ask the old man at least how much money? "

The confident smile on Yan Wan's face froze, and the smile gradually disappeared.

Looking at Wu Meiniang, she thought for a while, and then said weakly: "Thirteen essays?"

"That's right." Li Tai felt amused when he saw her disappearing smile.

"Is the concubine counting too slowly?" Yan Wan, who felt being hit, asked weakly.

"Wan'er has learned very well.

Everyone has their own strengths, Mei Niang is good at mental arithmetic, Wan'er is good at calligraphy and painting, don't force it. "

"But calligraphy and painting can't help your husband!" Yan Wan said with a wry smile.

"I helped, my husband will teach you how to draw later." Li Tai said with a smile.

Have nothing to do and want to help?

This is not right, I am short of a secretary who can draw and record.

"En!" Yan Wan nodded.

"Let's go, it's just that my husband doesn't want to do anything." Li Tai pulled Yan Wan into the study, then turned to Wu Meiniang and said.

"Meiniang, come and listen too!"
