The Zhang Zhonglang in Pu Yuan's mouth is the Si Jin Zhonglang general Zhang Yi.

Zhang Yizi is the heir of the monarch, and he is a well-known scholar in Shu County.

He was originally Liu Zhang's subordinate, defeated by Zhang Fei, and later served as Liu Zhang's envoy to the peace talks with Liu Bei. After receiving Liu Bei's promise to treat Liu Zhang with courtesy, he persuaded Liu Zhang to surrender Kaicheng.

Liu Bei thanked him for his merits, and first appointed him as the Taishou of Bajun; Later, the imperial court implemented the policy of salt and iron official camps, and he was recalled to serve as the first general of Si Jin Zhonglang, responsible for the manufacture of agricultural tools and weapons.

In specific practice, Zhang Yi and Pu Yuan are responsible for overall planning and scheduling, and inherit the imperial court; One is responsible for exploration and production, under the start of the craftsman. The two are old partners who have worked together for many years, with a clear division of labor and tacit cooperation.

After Jiang Wei and Pu Yuan rushed back to Chuyang, Zhang Yi was chatting with an elderly servant in the room of the post house, and he looked ruddy, laughing from time to time, obviously talking very much.

Jiang Wei looked around, but found that the servant was Tian Laohan.

When Tian Laohan saw the guests coming back, he hurriedly got up and went to pour tea.

Pu Yuan was upright, and first explained the location in detail, and then urged: "Please Zhang Zhonglang quickly report this matter to the military division and ask him to approve the establishment." ”

When Zhang Yi heard this, he stroked his beard and smiled: "The old man has met a talent in the past few days, and he was going to go to the military division; It just so happened that you even chose the site of the official railway, and the old man did two things together, which is really a good thing. ”

Jiang Wei asked: "When Mr. said talent, don't you mean Uncle Tian?" ”

Zhang Yi smiled: "Yes, it's this person!" “

"Ah......h

Just when his second monk was confused, Tian Laohan returned with two bowls of tea in his hand.

Zhang Yi pointed at Tian Laohan and said with a smile: "After staying here, the old man listened to this old man speak an authentic Chinese dialect, so he asked him about the local customs in Hanzhong. After some conversation, I realized that he was a farmer under Zhang Lu and was extremely familiar with farming......

Tian Laohan hurriedly bowed down and said with a smile: "It's not a farmer, the villain just helped the Heavenly Master plant the land for a lifetime." ”

When Jiang Wei heard this, he suddenly realized that this person was Zhang Lu's farmer, but he didn't know Mount Tai with his eyes.

Who is Zhang Lu? That is the famous Wudou Rice Dao Heavenly Master, before Cao Cao and Liu Bei fought for hegemony in Hanzhong, he was in Hanzhong for nearly 30 years, and he was the real master of Hanzhong.

During his reign, he devoted himself to the development of agriculture, encouraged agriculture, built new water conservancy, and governed Hanzhong into a paradise with "100,000 households and fertile wealth".

The grain output of the land under his rule was much higher than that of the surrounding counties, and everyone truly had food to eat and clothing to wear; He also set up "righteous houses" in various places, placing "righteous rice" and "righteous meat" to provide free food and lodging to passers-by.

Under his rule, the Han and Hu people lived in harmony and coexisted in harmony.

Guan Zhong once had a saying, Cang Liao knows etiquette and knows honor and disgrace when he has enough food and clothing.

If judged according to Guan Zhong's standards, Zhang Lu can indeed be called a person who is good at governing the people in the era of division of the people. And the biggest reason for his achievement is that he has planted a good land.

Since Tian Laohan is Zhang Lu's farmer, his farming skills are naturally first-class, and he must have impressed Zhang Yi with his knowledge of farming when he was answering the terroir of Hanzhong.

Seeing that Jiang Wei was deep in thought, Zhang Yi turned to Tian Laohan and said in a harmonious voice: "You just follow what you just said, and tell me why the yield per mu of land in Hanzhong back then was so much higher than that of the surrounding counties?" ”

Tian Laohan put down the tea and said busily: "Ouch, don't you dare, it's all some farming tricks......

He swallowed his saliva and said slowly: "Zhang Tianshi personally guides the people to plant the land every year, first of all, the seeds are disposed of in detail, he said that snow is the essence of the five grains, so he requires every household to store snow juice every winter, and when it is time to sow seeds, they use snow juice and seeds, so that the farmers can resist drought, do not grow locusts, and the harvest can also increase a lot......"

"After the first ploughing in spring, we should wait for the weeds to grow and then plough again, so that we can take advantage of the spring rain to sow seeds, so that the soil can be close to each other, the seedlings are alone, and the grass is filthy and rotten; In addition, the fields can also be fertilized with the feces of humans and animals, so that the yield of the fields can be increased by two to three percent......"

Although Jiang Wei is not familiar with agricultural affairs, after all, he has insight beyond the times, and when he heard this, he secretly said:

"That's the breeding and the application of fertilizers......"

"Zhang Tianshi also stipulates that the fields must be cultivated and planted."

At this time, Zhang Yi suddenly smiled and asked, "Boyo, you never went to the ground when you were young, right?" ”

Jiang Wei bowed his head and said: "I'm ashamed, I have my own tenants at home to handle farming, and Wei only knows how to dance knives and guns every day." ”

Zhang Yi showed a smile of "I already knew" and said, "Then I will ask Brother Tian to explain to you what ridge cultivation is." ”

Tian Laohan bowed down and answered "yes", and continued: "Ridge cultivation is to plant crops in rows on ridges, keep a distance between ridges, and the gap between ridges and ridges is called a ditch, and the ditch is used for walking and irrigation. ”

Zhang Yi took over the conversation and said: "There are strong and weak soil strength, but even if the land is fertile, after planting grain for one year, you can only grow some vegetables in the second year in order to restore the soil strength, which is called rotational rest." “

Hearing this, Jiang Wei nodded and said, there is no chemical fertilizer in this era, and after planting for a season, the fertility of the land does decline, and it takes time to recover, which is also the limitation of the times, and there is no solution for the time being.

But seeing Zhang Yi pause, his tone suddenly became excited:

Zhang Lu's ridge cultivation technique, its wonderful thing is that the ridge and the ditch are interchangeable between the two seasons of planting, each season after the harvest of crops, the farmer will plow the field again, then the ridge will become a ditch, the ditch will become a ridge, so that although the field is planting crops every season, but each ridge of land is actually cultivated in turns, which can ensure the soil fertility, and can continue to cultivate in the next year, so that if Yizhou can promote the planting technique, one hectare of land can be used as two hectares! Isn't it wonderful that the court will have twice as much land in vain? Just based on what Lao Tian said, the old man couldn't wait to recommend him to the military advisor. ”

But it was said that Tian Laohan talked about the old things, and the restraint was gone:

"Because the ridge ploughing is extremely labor-intensive, the Heavenly Master bought all the cattle raised by the Qiang and Hu people, ploughed them with iron ploughs on the flat land, and distributed tools such as rakes, hoes, and harrows to our common people. Hey, don't really say it, before the Heavenly Master came, the villain's family could only produce two or three stones of grain per acre of land; After the Heavenly Master came, it was common to have four stones and five buckets, and in good years, he could still receive five stones......"

"The Heavenly Master also built a lot of weirs in Hanzhong, and there are mountain and river weirs that are larger, and there are also a few small ...... here in Chuyang."

Jiang Wei listened to Tian Laohan talking eloquently, and sighed in his heart.

It is true that after more than 400 years of development in the Han Dynasty, some advanced farming techniques and tools have emerged.

However, in ancient times, due to the flow of population, farming technology did not spread quickly, and at best it was only popularized in the north, and the vast areas south of the Yangtze River did not even popularize cattle farming, let alone these more advanced and more expensive technologies.

Even he had seen many places in Shuzhong that were still in the stage of slash-and-burn cultivation.

What Zhang Lu did was to integrate the most advanced technology and tools in the world, start from the five aspects of planting, fertilizer, farming, tools, and water conservancy to form a set of effective planting system, and popularize it into the operation of Hanzhong, which has also proved to be effective.

It's a pity that Cao Liu and Hanzhong fought a battle, and the happy land he had finally created was beaten to pieces, and the people of Hanzhong were all moved to Guanzhong by Cao Cao.

This also means that although Shu Han occupied the land of Hanzhong, they could not completely inherit the farming system left by Zhang Lu.

But God was pitiful, Tian Laohan was too old, and the Wei army abandoned him, which cheapened the Shu Han court.

After all, there is an old man in the family, and there is a treasure.

Jiang Wei felt relieved, hugged his fists and said: "The military advisor must be ecstatic to meet such a talent, and he will definitely thank Zhang Zhonglang for his eyes like a torch!" “

Zhang Yi hurriedly waved his hand and said with a smile: "The military advisor is not far away, and the punishment is not close, it is the old man's luck to be able to serve him." ”

Today's Zhang Yi is the right-hand man of Zhuge Liang's administration, and he is also one of the representatives of the local people in Shuzhong to cater to Liu Bei.

He is fifty-six years old this year, but he still talks and laughs freely, and his words are full of admiration for Zhuge Liang.

This immediately caused Jiang Wei to think deeply-

It is said that there is a Jingzhou faction in Shu, and Zhuge Liang is the head of this faction.

But he has been in contact with Zhuge Liang for a long time, and from his daily observations, combined with the comments of others, he found that this theory is really Miao.

Zhuge Liang certainly has Ma Liang, Ma Tan, Yang Yi, Jiang Wan and other old people in Jingzhou; But he also reused Yang Hong, Zhang Yi, He Yuan, Pu Yuan, Qin Mi, Fei Shi and other Shu sergeants, at least the power of these people was not under the old people of Jingzhou; Even he was very restrained from the old people in Dongzhou and never took the initiative to provoke.

All those who came into contact with him admired him very much.

admired even the colleagues who were degraded by him, not only did not have the slightest complaint against him, but even after his death, they were all sad and frustrated.

Historically, Li Yan was like this, and so was Liao Li.

Therefore, if you really want to strictly say it, Zhuge Liang actually has no regional faction in employing people, as long as the lower-level officials are of good character and talented, they will be able to be reused by him.

Not to mention far away, it is he who descended to Jiang Wei and Jiang Boyo, didn't he also get Zhuge Liang's blue eyes? I'm afraid that when Old Man Tian sees him in a few days, he should also be reused.

"Zhang Yi is right, 'the reward is not far away, the punishment is not close, the lord cannot be taken without merit, and the punishment cannot be exempted from the noble power', this is where the selfless personality of Grand Duke Zhuge Liang lies, and it is also the magic weapon that he can closely unite the ministers after Liu Bei's death."

It was only at this time that Jiang Wei became suspicious of the Jingzhou faction for the first time.

But the big war is coming, and it's useless to think about it.

After this incident, after taking over Zhang Yi and Pu Yuan, he will naturally take over the responsibility of resetting the official railway.

The labor force of 100,000 people in Jingzhou will also blossom and bear fruit in the hot land of Hanzhong.

His mind gradually turned back. Tomorrow is the appointed period, and he will rush to Yangping Pass, and then move to the west near the military capital.
