"Long! --Prosperous! Prosperous! ”

"Drive! --Da! Da! ”

…………………

At dawn, the east was white, with a rumbling loud sound, the gate of Xuchang slowly opened, and then poured out countless figures, there were horses and majestic generals, there were civil officials who rode ox carts and high crowns and foreheads, and there were elegant and famous people who rode small donkeys and children in Tsing Yi...... The front and back are connected, and the stream is endless!

Many upper-class people traveled, and the officers and soldiers guarding the city were startled, thinking that there were earth-shattering changes in the imperial court, and everyone went out to flee, but later found out that the civil and military officials were not fleeing, but going to Zhengming School to watch a polo match!

There were many entertainment projects in the Han Dynasty, such as horse racing, bullfighting, cockfighting, and quail fighting...... Everyone has played it, but they have never seen a polo game, and driven by curiosity, they all want to open their eyes!

What's more, the initiator of this competition is Xiao Yi, who is in power and the opposition, who dares not to give face to civil and military officials and scholars and gate lords, so after receiving the invitation, they immediately prepared to travel, and they all got up early in the morning, for fear that being late would anger Da Sima!

There are two important reasons why civil and military officials have to come, one is that most of the young children in their family are in the Zhengming Academy, and many of them have also signed up for the polo competition.

Some shrewd officials have brought the girls in the family to be married to watch the game, and there are countless heroes in the academy, if you can pick a few fast sons-in-law, it would be great!

Second: Zhengming Academy is a 'gold-swallowing beast', the money, food, and materials consumed every year are enough to support tens of thousands of troops, and when the court is in the most difficult time, civil and military officials can't pay a fortune, and they don't dare to deduct a penny of food from the school!

Countless materials have been put in, and there must be some returns, and civil and military officials also want to see what results the school has achieved, if the revenue cannot cover the expenditure, it will not be so easy to allocate money and food in the future!

Although there are many teams traveling, the order is not chaotic at all, the noble ones are in front, the lowly ones are behind, no one dares to trespass casually, and the team that walks in the front is the 'tiger and leopard ride' of the Prime Minister's Mansion, surrounded by a Qibaohua car, which is not Cao Cao, but the two sons Cao Xiong and Cao Chong!

Since entering the Duke of Wei, Cao Cao's power has become greater, and his affairs have become more, getting up five watches every day, crawling in the middle of the night, dealing with the piles of twists and turns, and his body is tired, so he has the energy to watch the polo game, and it is not good to refute Xiao Yi's face, so let the fifth son Cao Xiong go instead!

Among the four sons of the Prime Minister's Mansion, Cao Xiong is the youngest and has the weakest personal power, and has been living under the halo of several elder brothers, which belongs to the neglected existence, but he has the best relationship with Xiao Yi, sitting on Xiao Yi's shoulder when he was a child, and letting go of a bubble of boy urine!

Cao Chong is smart and clever, and has the ability to never forget, so he is deeply favored by his father, and his family status is not below several sons-in-law, and even his personal learning is also taught by Cao Cao himself, so some people secretly speculate that Cao Cao's real heir is this eight-year-old prodigy!

However, Cao Chong has a smart mind, but he doesn't have a strong body, because of miscarriage - congenital insufficiency, he has always been weak and sickly, and he can't learn martial arts, and he can't help after taking countless tonics, I'm afraid it will be difficult to grow up!

This time, I went to Zhengming Academy to watch the polo tournament, and at the same time, I also wanted to ask the miracle doctor Hua Tuo to take a shot to regulate Cao Chong's body, whether it is to govern the country or to fight on the battlefield, you need a good body, otherwise you can only be a bystander!

The huge team went all the way to the east, about three miles away from the school, and was stopped by a large stone stele, the stele is one foot eight feet high, it is carved by a whole piece of white marble, and there is a line of big characters on it: The school is heavy, no noise, the civil official falls off the sedan chair, and the military general dismounts!

According to the ancient system, in some special places, there are such warning steles to show respect for rights and culture, such as dismounting 300 steps from the imperial palace and 240 steps from the prime minister's mansion...... And the rules of the Zhengming Academy: three miles away, all dismounted!

After seeing the stele, the civil and military officials voluntarily and consciously, either dismounted, or got off the car, even Cao Xiong and Cao Chong also got off the carriage and walked hand in hand towards the gate of the school.

There are only a few white-haired old Confucians, still riding on little donkeys, swaggering forward, they have no official positions in the world, but in the academic world, they all have great prestige, so they enjoy this privilege!

"Brush! Brush! - Now that the field is clean, weigh the corn and count the averages! ”

"There is too much rain this year, the growth of the dealer has been affected, we should build a drainage ditch, the previous only focus on drought prevention, but forget to prevent waterlogging!"

…………………………

On both sides of the road leading to the school, there are neat corn fields, under the blowing of the autumn wind, the ears have turned golden, and many peasant students wearing hats and cloth clothes are diligently harvesting and weighing the yield of each field!

Confucianism and Legalism must travel the world to understand the sufferings of the people, Taoism and Buddhism should comfort the people and let them abandon evil and follow good, Mohists invented various tools, and soldiers went into battle to kill the enemy and serve the country...... The farmer is to plant the fields well and let the people have enough to eat, which seems to be the simplest, but in fact it is the most difficult!

Although China is an agrarian nation, but for thousands of years, the people have hardly eaten enough, has been in a state of semi-starvation, if it encounters a year of famine, either starve to death, or rise up, how many great dynasties, are overthrown by the hungry people, and the reason why the people are hungry is not lazy, not stupid, but the grain production is too low!

In ancient times, the production technology was backward, basically slash-and-burn farming, relying on the sky to eat, that is, burning the wild grass into ashes to make fertilizer, digging pits and burying grain seeds, and then looking forward to the rain of God, if the wind and rain are smooth, you can harvest more grain, if you encounter a disaster, the grain will be poor, or no harvest!

"Historical Records" records: Ximen Leopard leads Zhangshui to irrigate Ye, with the land east of the Fuwei River, the mu produces two and a half stones of grain, the world is called the anointed land, the princes all show their troops on the side, and want to take it for themselves!

Two and a half stones is only three hundred catties, and after taking off the shell, it would be good to have two hundred catties left, such a pitiful grain output, but also made the princes red-eyed, and did not hesitate to launch a large-scale war, in exchange for the corpse mountain and blood river, the grain output of other barren lands can be imagined!

In the Han Dynasty, the cultivation technology progressed, and the longzuofa, ploughing method, ploughing, ox ploughing, and iron plough appeared...... The grain output has increased, and the average yield per mu is about 360 catties!

The peasants worked hard to produce grain, paid taxes to the state, paid rent to the landlords, how much can be left, the good years are half hungry and half full, the bad years are starving everywhere, since the two emperors of Huan and Ling, the population of the Han family has decreased sharply, and the starvation is far more than the war death!

"Dare to ask a few little brothers, the fields are cultivated by you, looking at the heavy ears, the harvest must be wonderful, I don't know what method to use?"

A middle-aged man walked out of the team, with big ears, dark complexion, and a shabby official uniform, who was the Prime Minister's Decree Shi - Liang Xi, who was in charge of Tuntian affairs and was most concerned about food!

The surrounding officials also pricked up their ears, hearing that the peasant students of the university traveled far and wide in search of good seeds, sowing putrid matter to improve the soil...... He also invented a lot of new agricultural tools, threatening to 'fill the official and private warehouses, and no longer suffer from hunger', I wonder if it is bragging?

"Back to this lord, the tens of thousands of acres of fields around the school are all cultivated by peasant students, but unfortunately we are not good at learning, resulting in the crop failure today, and there is only four stones per mu!

Da Sima said: a point of hard work, a point of harvest, the reason why the crops are not harvested, I think it is because of our laziness, we must work hard to plant experimental fields in the future, and then spread the technology and improved varieties to the world, so that the people can have enough to eat! ”

The peasant children are not good at words, and they still blush a little when they see the living, and they stammer to answer questions, and their hands are calloused, and their clothes are patched everywhere, and they want to come to work in the fields often!

In addition, their farming tools are also very peculiar, harvested, threshed, cleaned, and dried...... The variety is complete, easy to use, compared to the ordinary people use, but it is too advanced, and it is engraved with a 'ink' word, I think it is the invention of the children of the Mo family, right?

"The average yield per mu is four stones, and it is still a poor harvest, is the old man's ears deaf, or are the students lying, even if it is the best farmer and the best field, it is difficult to exceed three stones per mu?

Hearing is false, seeing is believing, let's cut a piece of land with our own hands, isn't it clear, not to mention the yield of four stones of grain per mu, can have a yield of three and a half stones, the old man must bow his head and salute! ”

For the peasant students said, hundreds of officials do not believe it, farming seems simple, but in fact it is extremely difficult, not to say that the invention of a few new farm tools, the introduction of some new seeds, grain production will increase by leaps and bounds!

When Zhang Qian went to the Western Regions, he also brought back a large number of plant seeds, which were selected, improved and cultivated by the people of the Han family...... In the end, the only ones that survived were walnuts, grapes, pomegranates, sesame, cucumbers, and garlic, and the rest were all eliminated by nature because of the lack of adaptation to water and soil!

When a seed spreads to a new place, it takes more than ten or even dozens of generations of planting to fully adapt to the soil, environment, and temperature...... If you are sure that everything is safe, it can be promoted on a large scale, and finally become a food!

Therefore, a person traveled to ancient times, took out corn and sweet potato seeds, and increased the grain output more than ten times at once, reaching a yield of dozens of stones per mu, and then created a peaceful and prosperous era, which is just the obscenity of some people!

(During the Wanli period of the Ming Dynasty, sweet potatoes were introduced into China, first planted in Fujian and Guangdong, and then spread to the Yangtze River and Yellow River basins, until the Qianlong period of the Qing Dynasty, before becoming a major food. ）

The civil and military officials did not go forward, rushed into the field, looked for a field that was not fat or thin, measured the size of an acre, and then tugged the official uniform to the waist, grabbed the tools of the peasant children, and began to harvest......

There are many people who are easy to do, but in just a moment, the hundred officials cut an acre of corn, and then threshing, bagging, weighing, and finally came up with a number - four and a half stones!

"My ancestor of the Shennong clan turned out to be four and a half stones per mu, fifty percent more than usual, and the students didn't say anything!"

"If you have warmth and the world is safe, as long as the people are fed, the Central Plains can see the peaceful and prosperous times, who dares to disobey the king?"

……………………

After seeing the accurate figures, the officials were shocked, some knelt down and kowtowed, and some silently wept, you know, there are tens of millions of farmers in the world, and the number of acres of land is about hundreds of millions, if each mu increases by fifty percent, how much grain should it be, and how many people can it feed?

"Dare to ask your little brothers, what methods have been used to increase grain production by 50%, and can it be extended to the world?"

"Answering the questions of the elders, it is nothing more than deep ploughing, watering and weeding, and using insects to control insects...... And some more grains of reincarnation! ”
