In Guangrao County near Judian Lake in Qi State, the green rice fields stretch as far as the eye can see. The wind blows the rice flowers, and the fragrance is fragrant.
Chen Mu, accompanied by Shiyi and others, took the students to inspect the rice fields and observe the people's sentiments.
As he passed by, every farmer working in the fields stopped and bowed to him.
The man wearing a hat took off his hat and saluted, the young man was in awe with a hint of envy, and the young girls looked shy, with a hint of affection in their eyes.
Whenever Chen Mu comes out of the county town, not to mention the empty streets, at least every married woman gnashes her teeth and stamps her feet with secret hatred. Every unmarried woman makes secret glances and expresses affection.
If he had not been protected by guards when traveling, he might have been drowned in the ocean by the sachets, flowers, and the crowds that were thrown at him.
It has to be said that Chen Mu, who is already 20 years old this year, has a formal and formal appearance. He is about 1.78 meters tall, has a slender body, white skin, and delicate facial features that can make any woman jealous.
Especially those pair of fox eyes, when looking at people with a smile, even men can't stand it, so much so that there are even powerful young men in Guangrao City who like masculinity thinking about it day and night, and they died of worries.
The title of the most beautiful man in Qingzhou slowly spread. Countless powerful daughters took notice of the news, and people who proposed marriage crossed the threshold.
"This Champa rice has plump grains and large ears. It is indeed much stronger than our rice."
Shiyi squatted on the ridge of the field, touching a bunch of rice and nodding with satisfaction.
"It's a pity that water conservancy cannot keep up, and there are severe droughts in Qingzhou from time to time, so we can only farm near the lake and cannot promote it."
Chen Mu thought to himself that in the Song Dynasty, half of the country could feed hundreds of millions of people by relying on Champa rice. Isn't it just because of the high yield of Champa rice?
Never mind that after thousands of years, the Champa rice produced in the Han Dynasty may not necessarily have such high yields.
In ancient times, when there was no knowledge of biology and no human intervention, it was impossible to change an entire population by relying on wild hybridization of plants? It was even more impossible to mutate genes.
So there must be no difference between the Champa rice in the Song Dynasty and the Champa rice in the Han Dynasty, unless a strong man descends from heaven? A man named Mendel or Yuan Shennong is born? Otherwise, there is no artificial promotion, and occasionally a wild high-yielding variety is born.
It cannot be spread.
"Master? If there is a drought, what should we do?"
The 11-year-old Chen Qun is like a little adult, following Chen Mu? As the monitor of the big class, Chen Qun is far more lively than Cui Lin, who is one year older than him. He is eager to learn and has countless questions every day.
Chen Mu said with a smile: "If there is a drought, we have to build water conservancy projects. During the slack farming season, we ask the people to open canals and dig lakes to store water for drought. We also need to build more wells and store food for emergencies."
"oh."
Many students were thoughtful.
Are these methods not invented by Chen Mu? Since ancient times, capable ministers and officials have basically used these methods to deal with droughts.
Taking students to the countryside? Just to teach them how to govern the world.
Go to the civilians to experience life in person, but in the future you will have to go to the battlefield to lead them to march and fight? Accumulate more practical experience, can't you imitate others? You have a good eye but a weak hand? You talk about the art of war and strategies one after another? In actual combat, they collapse.
At this point, is Liu Bei still a good judge of people? Zhuge Liang re-employed Ma Di, but Liu Bei said, "Ma Di exaggerates and cannot be of great use."
It can be seen that Liu Bei is indeed a model of knowing people and making good use of them.
"What if it's a flood?"
Chen Qun asked again.
Chen Mu thought for a while and said, "Then we have to plant more trees and dig more canals and lakes."
"More trees?"
The students looked at each other.
I have never heard that planting trees can also prevent floods.
"The biggest hazard of floods is that water flows everywhere and carries the soil. Such mudslides not only damage the fields, but also submerge the houses. Planting trees can lock the soil, and the soil can absorb water to prevent flooding.
.”
Chen Mu took this opportunity to briefly describe trees and soil erosion.
The situation of water and soil erosion in the Han Dynasty was not serious. According to the "Shui Jing Zhu", the Loess Plateau at that time was "shaded by miscellaneous trees, clouds hung with smoke, green cypresses smoked peaks, and clear springs filled the roof."
In addition, according to modern research, on the Loess Plateau during the Qin and Han Dynasties, the forest coverage rate reached 60% to 70%.
At that time, the Yellow River flowed with clear blue water, and the Yellow River rarely flooded and caused disasters.
It was not until the Song Dynasty that the population exploded and the economy developed, and trees began to be cut down in large numbers, the situation became very serious, and natural and man-made disasters continued.
Therefore, there are not many floods in the middle and lower reaches of the Yellow River at this time. They are all caused by heavy rains, and the most common ones are droughts.
If it is an ordinary heavy rain, you don't need to worry about it. But if it is the kind of heavy rain that lasts for many days and causes the rivers to swell, it is really necessary to prevent floods. It is necessary to build more artificial lakes to store water, dig more artificial canals, and various
Trees lock the ground to allow it to absorb water.
This is what Chen Mu is doing now.
After all, if he wants to promote Champa rice, it is inevitable that water conservancy facilities will be built on a large scale. While there is still money, building more canals, digging lakes and roads will do no harm.
First, when the people are off-farm, the government provides grain and pays a small amount of wages, so that the people can eat and make money during the off-farm, which is conducive to economic circulation.
Both, water conservancy facilities can prevent floods and droughts, which are very beneficial when fighting against natural disasters.
Third, Champa rice can gradually become popular and increase food supply.
Therefore, Chen Mu is now carrying out large-scale construction projects throughout Qingzhou, recruiting homeless refugees from Ji, Xu, and Yang, and asking them to reclaim wilderness, dig canals, and build artificial lakes.
Chen Mu came to Qingzhou to take office in November of the second year of Zhongping, and it is now May of the fourth year of Zhongping. In one and a half years, Qingzhou's population has grown at the fastest rate.
Not only is the political situation stable, the economy is growing steadily, even Beihai Donglai, which was once plagued by bandits, has been cleared of sea and rivers, and there are few bandits. This shows that his governance methods are quite good.
certainly.
This is because the land annexation in Qingzhou is not serious at present. The powerful people have been suppressed by Chen Mu's thunderous means. A large number of people have their own fields and can cultivate them, so there is no need to rebel.
If land annexation is serious and officials are unable to handle it, then no matter what administrative methods are used, it will be useless. People will still have to rebel if they should.
"It turns out that the land is compacted by the roots of plants. I always thought that the loose land was caused by too many plants."
Even Shiyi didn't expect that the earth and trees have such a relationship.
12-year-old Cui Lin has certain thinking ability. Unlike children in small classes, they learn whatever the teacher teaches and have no sense of resistance to authority. So Cui Lin asked: "Master, how can we prove the role of trees on the land?"
"It's easy to prove."
Chen Mu smiled and said, "You can set up a new interest group to find a piece of land without any plants, then find a piece of land with plants, dig with a hoe, and see which piece of land is more likely to be dug up."
"An interest group has been established again."
"Last time we wanted to verify the source of the wind, but we haven't been able to verify it yet."
"We have established more than ten interest groups this year. We have only used flame lamps to prove the upward flow of hot air. There are still many experiments to be done."
The children in the top class all had grim faces.
The flame lantern is the Kongming Lantern, which Chen Mu taught his children to make to prove the density of air.
Now the senior class has begun to do research projects, set up interest groups, and conduct various experimental demonstrations. This also allows them to prove some physics knowledge by themselves and strengthen their learning.
"Reading thousands of books is not as good as traveling thousands of miles. The knowledge in books is dead. Even if I teach you this knowledge, you will only have a partial understanding. It is not as simple and clear as doing experiments yourself."
Chen Mu touched Cui Lin's head and said with a smile: "When you learn from the past and the present and can become generals and generals, I believe you won't have the complaints you have today."
"Wei, Master!"
The children in the top class each raised their hands and saluted, indicating that they understood.
I inspected a circle of fields and then went to see the fishermen's fishing situation in Yanjudian Lake. The government encouraged fishermen to catch fish and shrimps in the water, so that the refugees could earn income from fish, which resulted in a bumper fishery harvest this year. Chen Mu went there, and the fishermen rushed to give away fatty fish.
, rejoice with the people, Pei Enjun.
In later generations, Judian Lake was pitifully small, less than 20 square kilometers, due to the reclamation of the lake. But now it covers an area of hundreds of square kilometers. Although it is not as vast as Yunmengze (Dongting Lake) today, which is as vast as the sea with 10,000 square kilometers, it is still
It is also endless and was called Shaohai at the time.
Moreover, due to the underdeveloped fishing gear and low fishing capacity in ancient times, the rapid development of fisheries in a short period of time will not cause an extinction impact on fish and shrimp. As long as the mesh is made larger, it will not affect the ecological environment and is a good sustainable method.
path of sexual development.
After inspecting Guangrao and Nanfeng counties for half a month, in mid-May, Chen Mu heard the good news of Liu Bei's victory. The inspection work here happened to be similar, so he returned to Qi State and continued teaching at Taishan Academy.
On the way back, I looked through the battle reports of Liu Bei's battle.
In March, Qiu Liju invaded Pingyuan Kingdom, burning, killing, and plundering. Chen Ji, the Prime Minister of Pingyuan Kingdom, could not resist, so he could only defend the city and wait for reinforcements from the court.
People living in villages and towns outside the city abandoned their homes and fled. Those who ran slowly were killed and plundered by Qiu Liju. Tens of thousands of people were killed or injured, and nearly 100,000 refugees were forced to move south to Jinan.
While Liu Bei sent people to appease the people, with Chen Mu's permission, he mobilized all his troops and marched north to meet the enemy.
It's just that the terrain of Pingyuan Country is really bad. There is almost endless plains in the Shandong Plain area, and the cavalry comes and goes like the wind. In the early days, Liu Bei had a very difficult time, losing many battles. Facing 30,000 light cavalry was miserable.
"Six Dances" records that King Wu of Zhou asked Jiang Taigong how to calculate the combat effectiveness of infantry and cavalry. Jiang Ziya said that on the plains, one ride should be eight steps, and in narrow mountainous areas, one ride should be four steps.
The Song Dynasty's "Wu Jing Zong Yao" believes that one cavalry is equivalent to five infantry.
This was still the case in the Northern Song Dynasty, which already had various methods to deal with cavalry, but in the Han Dynasty, it was even more difficult to do so. It was also a plain area, which shows how difficult it is for infantry to fight cavalry.
Although Liu Bei also has a thousand heavy cavalry and three to four thousand light cavalry, the heavy cavalry cannot catch up with the light cavalry. Cavalry guerrilla warfare on the plains is too difficult unless they have the same type of troops.
Liu Bei's 50,000-strong army fought with Qiu Liju for half a month. After being defeated in the field battle, they had to defend the city to avoid being annihilated by Qiu Liju's counterattack.
After a stalemate for a period of time, Qiu Liju saw that the looting was almost complete and planned to withdraw to Liaodong instead of fighting Liu Bei.
As a result, the imperial army just arrived, and Zou Jing arrived with tens of thousands of reinforcements and stationed himself in the Hejian Kingdom.
Zou Jing not only brought reinforcements, but also brought an imperial edict, making Liu Bei the Cavalry Commander and allowing Liu Bei to go out to fight in Qingzhou.
This was the result of Chen Mu's letter to fight for Liu Bei's righteous cause of sending troops.
Otherwise, just with the official documents from Chen Mu, the governor of Qingzhou, Liu Bei could only send troops to the plains and not to the Bohai Sea in Jizhou.
With this edict, Liu Bei can be justified.
Zou Jing has 40,000 horses and Liu Bei has 50,000, making a total of 90,000.
Coupled with the county soldiers and cavalry from various places, the cavalry is close to 10,000, and the total force exceeds 100,000. It can compete with Qiu Liju head-on in the wild.
Xun You knew that Qiu Liju had plundered a large amount of wealth, and his actions were bound to be slow and not as fast as the initial plunder. So he suggested to Liu Bei that he should use the strategy of encircling Qiu Liju on all sides, gathering troops from two counties in the plains and rivers, and encircling Qiu Liju in the Bohai Sea.
, let’s close the door and beat the dog.
There is a flaw in this strategy, that is, if Qiu Liju becomes desperate and abandons his baggage, leads his cavalry out of the encirclement, breaks into the hinterland of Jizhou and Qingzhou, and causes chaos everywhere, it will be a very troublesome matter.
For this reason, Xun You worked hard to formulate a plan, think of ways to shrink the encirclement, formulate ambush points, and improve strategies.
Finally, through the intelligence from the Military Intelligence Department, Qiu Liju was finally intercepted in Zhangwu County, Bohai Sea.
In this battle, Liu Bei adopted Xun You's plan, and after discussing with Zou Jing, he organized an encirclement from the south and west, opened an opening to the north, forced Qiu Liju to flee north, and released him back to Youzhou.
After the war, Qiu Liju did not go south or west as Xun You expected.
After all, Qiu Liju is not a fool. If he goes to the hinterland of Jizhou and Qingxu, he will be far away from his home base. No matter how hard the cavalry can run, there will be times when some people are trapped and their horses are exhausted. Once they are surrounded by the officers and soldiers, it will be a dead end.
Now that there are no enemies in the north, it is natural to choose to return north.
So Qiu Liju left behind more than a thousand corpses and more than half of the baggage, and fled northward at a speed slightly faster than the infantry.
I still can’t give up so much money, and I’m not greedy enough.
It's a pity that Qiu Liju forgot that there was Gongsun Zan waiting for him in the north.
Gongsun Zan went to Xianbei and spent a lot of money to hire a group of Xianbei people, and intercepted Qiu Liju in Quanzhou (today's Jinwuqing District).
A wolf in front and a tiger in back. After a day of fierce fighting, Qiu Liju suffered heavy casualties, with six or seven thousand people dead. He had to abandon all his baggage before leaving the battlefield and escaping back to Liaodong.
As a result, during this trip south, Qiu Liju killed 800 enemies and suffered 10,000 losses. Not only did he get no benefits, but the tribe's population also decreased by one-twentieth, which was a huge blow to him.
After reading the battle report, Chen Mu also admired Xun You's strategy.
In ancient wars, it was indeed extremely difficult to deal with cavalry in plain areas. The only way was to encircle the cavalry through human sea tactics, and the success rate was very low. In the Song Dynasty, which had the most infantry-cavalry wars, cavalry often ran away without being able to fight, and the infantry could not catch up at all.
The case above.
Although Xun You also chose the siege tactic, he used a hard-to-play tactic. He first forced Qiu Liju to go north by flanking him on both sides, and then arranged for Gongsun Zan to ambush him on his way north, forcing Qiu Liju to flee in panic.
The tactics are really well laid out.
Now the imperial court ordered Liu Bei, Zou Jing, Gongsun Zan and others to send troops to Liaodong to put down the rebellion of Zhang Chun, Zhang Juqiu and Liju. The situation now is much better than in history.
It seems that there is no need to wait until Liu Yu takes action next year.
Next, you have to plan something else.
Sitting on the carriage, Chen Mu thought to himself.
