Mi Huang followed Cheng Jia into the greenhouse, and saw that the vegetable farmers inside were watering, and then he called the vegetable farmers out, only to lift the corner of the light veil, revealing a handsome face, and then pointed to some rice seeds that were being soaked in the basin and said, "These are breeding." ”

"Breeding?"

Mi Huang curiously looked at the bubbling seeds in the clay pots that were growing green shoots, and couldn't help but probe into the water with his hand, and took them out curiously to take a look, "Aren't the seeds scattered directly in the ground, how do you plant them with water here?"

"At the seed stage, the seeds have the greatest demand for water, and they are often sprinkled directly in the land, because the survival rate is not high due to uneven moisture, and direct hydroponics is much faster. We foam the seeds with cold water, wait for the rice seeds to germinate, and then after the germination, I will order the farmer to sow the sprouts on the seedbed that has been ploughed in the greenhouse now, and then cover the soil, hand over enough water, and when the seedlings grow, the first crop of rice will be harvested in August, and I can order the people to plant the second crop of rice at the same time. ”

"What is the second crop of rice?"

Mi Huang has never heard of this word, "Isn't it possible to plant rice only once a year?"

"Our Chu country is located in the south, the climate will be warmer than the north, in fact, if the time is tight, we can plant two crops of rice a year, and harvest another round of rice at the end of November, which is equivalent to we can harvest grain twice this year. ”

Cheng Jia pointed to the rice field with rice flowers floating outside the greenhouse and continued, "You see that now the 100,000 acres of rice fields are already blooming, and they are about to bear rice ears, and now I raise seedlings through the greenhouse, and when the time comes, I will harvest and sow new seedlings at the same time, and the two will not be delayed, and the farmland will not be idle after August and September, resulting in the farmers having nothing to do in the autumn and winter, and it has doubled the grain for my Chu country." ”

Mi Huang was stunned when he heard this.

Su had never told her about two crops of rice, but a bumper harvest of 100,000 acres of land was already quite considerable, and what would happen if she planted two crops, and then doubled, what an amazing yield it would be.

Although the two wearing hats are eye-catching, but they have never caused the people to watch along the way, and then listen to Cheng Jia's "two seasons of rice" that they have never heard of since ancient times, Mi Huang has been shocked from the bottom of her heart, she doesn't know how Cheng Jia came up with it, and then they visited the waterwheel, visited the new way of operation, and even visited the new farm tool factory......

"Is this the greenhouse?"

When the woman saw the waterwheel, she would ask, "How did you and Gong Nian come up with this waterwheel?" How can such a big wheel run on its own and carry water up?" ”

"Do you see the waterfall running down the hill over there? That's what drives the waterwheel. ”

"What's the motivation?"

"Just like a horse-drawn cart, a person pushes a plow, these are all using force, and the water falling down will produce an impact force, and falling on the point of the waterwheel will push the operation of the waterwheel, and the flying flow will not stop, it will produce a permanent force, which has been urging the waterwheel to run, without relying on any human power. ”

"But how do you pull a plow with an ox pulling a cart, it's too wasteful, isn't it?"

Horses and cattle were still the property of the nobility at this time, the woman asked, pointing to the farmer in the field with a whip and a plow to push the ox.

"This is an ox-drawn plow, a year compared to the ox-drawn cart, a tool, which can save a lot of manpower, often people as long as the back of the cattle can quickly plow the land, this is the fundamental reason why we are now 100,000 acres of barren land so fast, purely by manpower to push the plough is like purely relying on people to walk, which one do you say fast?"

"Is the ox cart fast or the human fast?"

"Of course, it's the ox cart fast. ”

Mi Huang replied without thinking.

But such a simple truth, from the Spring and Autumn Period to the Warring States Period and then to the Eastern Han Dynasty, after hundreds of years, the Chinese nation gradually understood.

Of course, this is also related to the fact that cattle and horses were too scarce at that time, and only the aristocratic class used them.

No one would be willing to plough the land with such a valuable animal.

The price of a cow is much higher than the price of a slave.

The ruling class at the top is basically born into the aristocracy, does not work in agriculture, does not understand agriculture, and does not know these details at all.

"This young lady, the old man, I have pushed the plow all my life, and I used to be the first strong king in our village, but since Cheng Youtu and Gong Lose made such a thing to pull the plow, basically nothing has anything to do with me, I wave the whip in the back, and the cows keep running in the field, and the ground is also plowed......"

An old farmer who was resting in the field heard their conversation, took off the straw hat on his head, walked from the field to the edge of the ridge and knelt down to salute them and said, his eyes were full of love for the land and gratitude to Cheng Jia, "Old man, I have planted all my life, I really have not been so easy, I saw the water flowing in our eastern suburbs, but did not urge our farmland, all this is the blessing of the right disciple, he is the most merciful nobleman." ”

Cheng Jia smiled and nodded to him when he heard this.

Nowadays, many people in the eastern suburbs do not know the truth and deify him.

But one day, history will drown everything, and they will no longer remember who invented it, but just learn to use it to create greater value.

Pointing to the land that the old man had just turned over, Cheng Jia took the phoenix and walked forward again and said, "You see that the old man just now could only plow one acre of land a day, but now he can plow ten acres of land by himself in the eastern suburbs, so now I only need 500 people and 20 days to complete the work of 100,000 acres of wasteland." ”

"Last time I taught you arithmetic, let's do the math, 500 people * 10 acres of land / day / person * 20 days = 100,000 acres of land. ”

"In the past, it would take at least 5,000 people to complete it in 20 days, or 500 people, it would take nearly half a year and 200 days to complete, how fast do you say?"

The more the accounts are calculated, the clearer they become.

And Mihuang also immediately realized the great role of a small plow pulling tool for farming.

"What you mean is that just like the impact of chariots and cavalry on the infantry, walking on the road, horse-drawn carts and ox-carts are faster than walking, and in agriculture we can also use this kind of agricultural tools similar to weapons and vehicles. Mi Huang quickly drew inferences and said.

"Yes, in a way, the waterwheels you see and the ploughs are just tools that help us with our farming. Tools help us free our hands, and what are we doing with our free hands?" Cheng Jia took Mi Huang to the tent he set up here, pushed open the door, and they saw some of the account gentlemen they had seen in the last Zhou Mu Jinku case to assist in the investigation, and two or three of them were "crackling" with abacus inside.

"What for?"

Mi Huang followed his question, looked down at the tent He Lao, who seemed to be calculating the investment in the eastern suburbs now.

"We can calculate how much human, financial and material resources we need to use, and do something reasonably. ”

The extensive economy is to pat the head and do things, purely by imagination.

As a result, such a large number of officials have also appeared in society.

Do what you see is good.

Without considering your actual situation, you can prescribe the right medicine.

Cheng Jia pointed to the evaluation table of the eastern suburbs that He Lao had just calculated, and said slowly, "You see, our Chu State actually has a financial budget every year, but it is still very simple at this stage, you know, basically how much to spend, calculate the approximate."

For example, in this Northern Expedition, in addition to the royal expenditure, Ruo Ao and the major families jointly raised money and donated materials.

But in the future, when we can one day accurately calculate and predict that in the next year, I will put 3,000 displaced people, 100,000 mu of land, 10,000 stone seeds (about 100,000 catties), 100,000 gold baht, and when there is no flood, 1 catty of seeds per mu of land can produce 3 stone millet (about 300 catties), and when we estimate that 300,000 stone millet will be harvested in August and September, we will be able to know how much manpower, material resources, and time can be achieved in agricultural input every year. ”

Accounting is an economic mathematical problem that can be calculated using the most superficial addition, subtraction, multiplication, and division.

"Well, but the budget is not enough, I heard Su Cong say, what else is needed in the early stage, and the land is inspected to ensure that the implementation effect in the later stage is perfectly realized. The woman nodded and asked again.

"So I looked for this place for a long time, let the Sigong Mansion recruit a lot of experienced farmers, and asked many places within a radius of 100 miles outside the city of Yingdu, and found that there are a few places that are not bad, but it is too far away from Yingdu, the transportation is inconvenient, this is the closest place to Yingdu, and it is also a tributary closest to Hanshui and Yunmengze, after the crops are ripe, we can use the car along the newly opened road to Yingdu, or take the waterway, through Yunmeng Daze and Hanshui to other counties.

In addition to paying attention to the convenience of transportation in the early stage of site selection, I am thinking that the terrain of this place should not be too low, otherwise the field will be flooded in case of flooding, so as to avoid flooding, it is best not to be in the place of Shanyin, the sun is not enough, the crops will not grow well, there must be a water source next to it, there is a water source to irrigate the land, the soil quality can not be too acid or too alkaline, otherwise it is not suitable for various crops......

Therefore, in the future, we must pay attention to these elements when we choose to open up wasteland, so as to ensure the normal growth of crops in the field, and it can be easily transported out quickly in the later stage. ”

"How can you, a noble son, know how to farm? Do you know so much? Taishi Pan didn't teach us these ......?"

The more the woman listened, the more surprised she became, and finally asked in confusion.

A lot of things, if it weren't for Cheng Jia's personal explanation, just listening to Su's introduction, she didn't know that there were still so many harsh requirements in the original eastern suburbs site, she asked herself that she had been in the palace and outside the palace for so many years, and got along with some low-level palace maids and soldiers, and she hadn't heard that farming had such a big knowledge, as well as arithmetic, all Chu, Cheng Jia recognized the second, and even the golden horde Liu Lao under Ruo Ao Ziyan did not dare to admit the first.

"Learn from the doctor, planting herbs is more demanding than growing food......

The man glanced back at the old doctor who was collecting medicine in the medicine field not far away, and said with a cough.

"Doctor ......"

Mi Huang's gaze also fell on the old man who looked like he could only nag every day in the distance, but he didn't expect that in addition to medical skills, he also understood, "Why don't you recruit the old doctor into the Sigong's Mansion or recommend him to the Imperial Hospital?"

I saw that he was directing the farmer to dig herbs with a small hoe over there, and scolded at the top of his voice, "As long as the leaves of the herbs don't have stems, why do you even dig up the roots, and it's not a reed (radish)!!"

"Ahem, have you gotten along with him, doctor? His temper is stinky and big, and he won't harm your cousin when he goes to the Engineer's Mansion, and even the head of the Zheng Yuan can't stand his broken temper. "Cheng Jia secretly betrayed the old doctor.

Mi Huang nodded, this old man does have a big temper, he has never been very respectful to her, he is all pretentious, and even Cheng Jia is scolded by a dead boy.

The doctor looked at the two of them standing outside the medicine field, looking at him intently.

A pair of eyes narrowed small, and a glimmer of light crossed it.

Hehe, laughing.

"Stinky boy, did you bring your daughter to inspect the work?"

"Hmm. Cheng Jia nodded distemperedly.

"Lady, how about looking at the eastern suburbs?"

"Good. Mi Huang also nodded without temper.

"Okay, stinky boy take the lady to see more!"

"Uh-huh. ”

An old man calmly commanded Cheng Jia to do a good job of inspecting the princess as if he was the biggest leader, and all the farmers looked at the old man in the medicine field with awe, and then he said whatever he wanted, and he did it very carefully and carefully.

In the evening, the old doctor checked the herbs he had ordered the farmer to take care of during the day, and some herbs that were easy to grow with a short cycle were growing well here, and then he collected a basket of herbs and put them on the long case, looked at the young man behind the long case and asked, smashing his mouth, "Why didn't I know that I taught you to farm?"

"Did I teach you in my dreams?"

"Uh...... What I read in the book ......" Cheng Jia paused with the pen in his hand and replied dumbly.

"Which book...... Lend me a look and learn ......" The old doctor spread his hands and asked him for it.

Baidu Encyclopedia......

Or he'll write a copy.

This night, Mi Huang lay on the bed tossing and turning and couldn't sleep, she felt that what she saw with her own eyes and heard with her own ears seemed to be as simple as these truths, but Cheng Jia seemed to suddenly open a new door for her, and what she saw when she opened the door was a new world like the eastern suburbs.

She has an increasingly strong premonition that no matter how well Ren Chengjia does her secrecy work now, when the autumn harvest is in August and September, she will definitely be unable to hide it anymore, and more people will come here. [.]
