In the winter, Shi Tong personally took his two sons to build a light and somewhat strange plow. The iron used on the ploughshare was made by a blacksmith he found to be familiar with, for which Han Chuan also paid a sum of money, but fortunately the Shi family gave him the reward money later, otherwise the family would be nervous again.

After doing this, because the spring plowing had not yet begun, they were not in a hurry to go to the field to test, so Han Chuan taught them to make a cylinder car again.

Huaiyin County near the water building, as early as Shixing to offer the water mill, Xianyang there is no reward when there is no reward, the county order has ordered the engineer to take the craftsman to build a water mill house by the water, and now the happiest people are the number of cangqiang in the county. There is a lot of rice in the south, and the county officials and garrisons eat rice every day, and day by day in order to complete the task of rice cooking, he is also eager to get all the women who commit crimes to eat rice.

However, this work is extremely arm-intensive, that is, to force these concubines to death, they do it from morning to night, the more they lick, the slower they go, the more useless they kill, but one less labor.

But in the previous year, with the first stepping, these weak women can work longer in a day, and it is faster than pounding rice.

Then there was a water mill, since the water mill house was built, the water flowed endlessly, and the concubines did not stop, changing shifts to guard in the water mill room, bags of rice fell, and a handful of white rice was taken back. He doesn't have to rush tomorrow's amount today, and although he can't make rice together for the sake of preservation, he can easily complete the supply in a county as he eats.

Therefore, when he heard that Shi Xing and Shi Cang had made something new and were going to test it in the field today, and the engineer was about to go to see it in person, Xu Pu, the cang, didn't say a word, and went with him.

Tian Qiangfu Tao and he befriended, originally said that it was good to use Xiu Muri to play nearby, he went, Tao and couldn't sit still, the Tao is used in the ground, I should also go to see, and I also participated.

Taoxi is outside Huaiyin County, which alarmed the officials in these counties. If they live in a home, I am afraid that it will only attract the attention of the villagers.

Shi Tong is taking his two sons to install a cylinder car in his own land.

Shi Xing was allocated 100 acres of land last time, but the land allocated was not very good, although it was near the water, but the land was high and the water was low, and it was inconvenient to irrigate. During the period of building the cylinder car and the curved plow, Shi Tong asked the subordinates assigned to the family to dig the canal, and now it is just right to use it.

Engineer Chen Cheng, Cangqiangfu Xu Pu, and Tian Qiangfu Tao looked at this thing, and the engineer had already seen the mystery and rubbed his hands excitedly. If these brothers come back a few more times a year, he will definitely be promoted! If you have a position, you may still be able to take up a post in the county.

Xu Pu and Tao You hadn't seen the name until the cart began to turn, lifting the water from the low to the high and falling into the aqueduct and flowing into the fields, that they opened their mouths in surprise and glanced at each other.

This matter has little to do with Cang Qiangfu, but Tian Qiangfu is also excited. Although the craftsman's business has nothing to do with him, this thing is extremely useful in a place like Huaiyin, where water is abundant, and it can even be operated without manpower. Not to mention the farmers, there is also a lot of land in the official fields that is inconvenient to irrigate, so if they are all used......

"Engineer! Hurry up and build, hurry up and build! ”

The engineer nodded again and again, but the cangqiang man didn't do anything to himself, and was much calmer: "Report to the county order first." It's going to be expedited to Xianyang again. By the way, there's one more thing, what is that doing? ”

"That's a Quyuan plow!"

Xu Pu lowered his head, and saw a country boy standing not far away, grabbing a small straw ball in his hand and throwing it to play, what he said just now was what he said. There was also an older boy next to him who took his hand, and when he looked over, the older boy saluted, and the little boy did the same as he did. Pu Sheng has a good impression, a country naughty boy, and a little bit of etiquette.

He ignored the two colleagues who were still stretching their necks to look at the cart, walked over and asked kindly, "What zigzag plow?" ”

Han Xin stretched out his hand and pointed to his field, "The new plough that my father taught me to make can be pulled by a cow, and everyone is watching." ”

Shi Tong's family installed a cylinder truck here, which originally attracted a group of villagers to watch. As soon as several county officials came, those people avoided them in awe. Previously, the three engineers were still amazed at the cylinder car, and the engineer carefully checked the structure of the cylinder car and calculated how many people it would take to complete this one; Tao He thought about how many fields in the official field needed to be irrigated, and the engineer was rushing to work, and if he could use one-third of it this year, how much would he increase the harvest. Only Xu Pu, the cangist, has little to do with this, at most, he will have more grain to manage this year, which cannot be his credit. That's why he noticed Han Wu's answer and walked over to ask.

Hearing Han Wu say this, he was taken aback: "A cow? ”

Han Xin nodded: "One head." My family has a cow ploughing the ground. ”

Although Xu Pu is not an engineer or a field husband, he also has land in his own family, and he is no stranger to farming.

It's okay not to look at it, but at a glance -

"A cow!" He blurted out.

In Han Chuan's field, the ploughing ox he just bought this year is pulling a plow. Xu Pu held his breath, but he still didn't think to call his colleagues to come and see.

One cow only needs one cow. He is a county official, and his family does not worry about ploughing cattle, but Pu knows that if the official field is only pulled by an ox, it can save a lot of manpower, and even more wasteland can be cultivated.

Just thinking about it, Xu Pu suddenly found that his friend Tao He was not around, so he wanted to call him to come and see. At this moment, the villagers shouted and shouted again. It turned out that the ox rushed to the ground, and under the drive of Guo Chuan, it easily pulled the plow and turned around.

The people gathered here to watch the bustle were all farmers, all of whom had experienced the fatigue of man's ploughing and the heaviness of oxen ploughing, and how could they not exclaim when they saw such a light turn.

Lian Pu also shouted, and then turned his head and called: "Tao You, come quickly!" ”

Tao He finally came back to his senses from the calculation of the cylinder car, and hurried over a few steps, also in shock.

When he turned around again, he let out a long breath of relief and patted his friend's shoulder: "Pu, it seems that I am going to be one step ahead of you." ”

With a solemn expression, he saluted the engineer who came over at some point: "This year's harvest is going to be entrusted to the engineer." ”

After the Xianyang edict, the whole country began to promote these two things, where did he still seem to be credited, and the credit was all the engineer's. Only when he reported and rushed to work in the county, and used it one after another during the spring ploughing period, he could get the credit for catching up with a tail - the important thing was to irrigate the land and collect more grain.

The engineer rubbed his hands and said excitedly: "Take your own life!" ”

Within a few days, the plough and the drum cart were already on the road. This is the Shi family father and son did it together, Shi Tong was afraid of diluting his son's credit, refused to admit it, only said that the two brothers did it together, he was a craftsman, the family also farmed, and knew their significance to farming, so he hoped that the two sons could get the title by this.

His two sons should be knighted. I just don't know if there will be a reward for the merits of my wife and nephew. He doesn't know Qin Law very well, he only knows that craftsmen will be rewarded for making useful things, but his wife and nephew are not a hundred workers, how can it be calculated? If it is based on the credit that is beneficial to farming, it should be able to be counted. But if you don't count, then I'm sorry for Han Chuan.

This was all Han Chuan's idea. Qin Lu is too rigid, if he is still the king of their Chu State...... Shi Tong hurriedly pressed the idea of cutting off his head. They are now Qin.

Moreover, although the king of their Chu State did not care who offered it, he did not necessarily care about these things. In this way, King Qin is more generous.

Hey, there has always been a story of He's Bi among their craftsmen, and the king of their Chu State is really unreliable.

Han Chuan pulled the plough with an ox, and the land was ploughed much easier than in previous years. The method in the Book of Heaven needs to be cultivated intensively, and he has a lot of things to do, and he estimates that he is too busy to be busy, so he still asks Chen Yuyong to cultivate. The two are already familiar with each other, and there is kindness between the host and the guest, which is much less contradictory than with others, and it is also worry-free.

Han Chuan himself only carefully tended to the few acres of land set aside.

In the backyard, the two crops that I asked for last year were planted one after another, and this was the busiest time.

He sat under the tree at the head of the ground and met Weng, as if he had a short rest after work, thinking about the high-yield grain varieties in the book of heaven, he secretly sighed, and said in his heart: "Even if it is so high-yielding, how many grains can fall into the belly of our and other leaders?" A slight increase in the yield of rice, wheat and millet would only increase the amount of taxes to be paid. Tired and tired, in the end, it is not barely enough to survive. However, these so-called coarse grains, which are high-yielding, labor-saving, not picky, difficult to store, and easy to vomit for a long time, can become our life-saving food for famine. Although the immortals have compassion for the world, they are ...... in this world."

Han Wu was also squatting in the backyard at this time, watching his brother take care of the sweet potato seedlings that had just been planted, and chatting with the system: "If this is planted, you won't be hungry." ”

The system cautiously reminded him: "Plant a sweet potato, it has to be detoxified." In the data, this yield is the result of the combined effect of fertilizer machinery and detoxification, and your father must be much worse in this era. It also has a high moisture content, leaving only about a quarter of it after drying. To make vermicelli and eat it, you have to count it as one-fifth of the amount. ”

Han Wu was splashed with cold water all of a sudden, and his face wrinkled. He saw that the yield per mu of sweet potatoes was more than 8,000 catties according to today's algorithm, so he naturally felt that it was okay, very good. But according to the system, it seems that it has to be discounted and discounted, and it is not known how much is left.

My father was going to work in the fields, and my mother and brother were busy in the backyard. It's not productive, why are they working so hard? Han Wu wanted to tell his mother not to do it, but fortunately, the system spoke in time.

"The way of cultivation can be ignored, and your father's cultivation according to the method we have summarized has surpassed this era. Then you can refer to a certain dynasty in our time and space, there are no other conditions, only manpower and ordinary fertilizer, and the yield per mu at that time can reach more than 2,000 catties close to today. However, the sweet potatoes stored in the warehouse that can be used in this era are varieties that have been improved after human beings go to space, and it is not a problem to double them, and they can have more than 4,000 catties if they are planted well. But it's ...... than you think it's 8,000 pounds."

Before he finished speaking, Han Wu had already cut off.

"How much worse can I be, what do I want if I have more than 4,000 pounds, I really want to go to heaven!"

Sweet potatoes are large, and it is not easy to use "stones" to calculate, only by weight. The harvest of 4,000 catties of an acre of land is 1,000 catties of sun-dried, and there are 800 catties of vermicelli that are processed into vermicelli. The system is really a little mentally retarded, not as good as a child like him, who doesn't know anything about human suffering.

"After harvesting sweet potatoes, you can also plant wheat again, the same as the one given for free, how happy my father and mother are."

This sweet potato fertilizer is used relatively little, and it does not pick the ground, although it is easy to perish, but there is also a mature storage method, which can be stored for several months. It can be connected with the seed wheat, except that it cannot be repeated on a piece of land, it is simply a godsend in this era.

Han Chuan didn't dare to choose another potato that seemed more suitable as a staple food, because according to the book of heaven, that thing was toxic after germination. He has never seen inexperience, in case he really poisons someone, his life is not enough to compensate.

And if you want to have a high yield, it seems that that the potato needs more fertilizer, and it is not as good as sweet potatoes, so you can have a good harvest with compost and plant ash. However, it can also be grown in that kind of barren land, but the yield is not high, and it would be nice if it was not toxic.

Now this sweet potato has the same trouble as that one, which is detoxification. It is also not possible to cultivate continuously on the same plot. However, this thing has a high yield per mu, so leave an acre and a half of land to plant it in turns, and it is not a variety of things, and it is very suitable for famine relief.

It can only be stored for a few months, which is not comparable with corn and rice, which can be stored for several years, and the king will not collect it as a tax, which is a disadvantage for the poor.
