Da Qin: Comparing his sons, Ying Zheng was sour.

[Between the three words of King Yingzheng of Qin and Prince Fusu, it was generally decided that there would be publicity and promotion of the "Daitian Law", the car, the Quyuan plough and the ploughing ox in the future. 】

[Then, Prince Fusu turned his head and looked around, and found that Xu Zi and other peasant children were holding all kinds of farm tools in their hands, and they were looking at him expectantly at the moment. 】

[Prince Fusu touched his cheek, feeling that there was nothing dirty, and couldn't help asking, "Why do you look at Lone like this?"

[Xu Zi coughed lightly twice, and said seriously: "Ahem, cough, Your Highness, take a look at other cultivation tools, do you have any ideas for improvement in your heart?"

[After harvesting the two great cultivation tools of the cocoon and the quyuan plow, Xu Zi and other peasant children also tasted the sweetness. 】

[I want to see if Prince Fusu can also make improvements to other farming farmers, if so, then their cultivation efficiency may be able to speed up several times.] 】

[What a blessing this is for their peasant children, and even for the people of the world!]

[Hearing this, Prince Fusu also shook his head with a helpless smile and said: "Lone also wants to continue to improve more farm tools for the people of Qianshou in the world, but now Lone looks at these farm tools and doesn't have any good ideas for improvement. "】

["So let's put down these farm tools for the time being, if Lone has a whim and thinks of ways to improve other farm tools, then Lone will definitely come to you as soon as possible."] "】.

["Xu Shi and Ji Shangshu each left their second and third sons to accompany Gu and their father to continue their patrols, and the rest of the people will disperse separately. "】

[Hearing the order of the crown prince Fusu, Xu Zi and Xiangli "637" In addition to leaving two or three peasant children and Mo family children to accompany them, other peasant children and Mo family children also dispersed. 】

["It's rare to come to the Sixth Division of the Ministry of Agriculture, so Master Xu will take Gu and his father and others to inspect the Sixth Division of the Ministry of Agriculture. "】

[Prince Fusu looked at Xu Zi and said warmly. 】

[Xu Zi also did not hesitate, nodded directly and responded: "Yes, Your Highness, please also ask Your Highness and Your Majesty to come with me!"]

[After speaking, Xu Zi took Chen Xiang and Chen Xin, two peasant children, to lead the way. 】

[And the crown prince Fusu and Qin Wang Yingzheng are strolling behind. 】

[And behind the crown prince Fusu, there are Zhang Han, Xiang Liji, and several other Mo family children who follow him. 】

[As for the back of King Yingzheng of Qin, he followed Zhao Gao and several eunuchs and attendants. 】

["Previously, we were in the Farming Methods Group of the Ministry of Agriculture's Farming Division, but now we are passing by the Tianshi Group. "】

["According to what His Highness said before, the Tianshi Group has seven teams, which are responsible for verifying the old calendar, calculating the new calendar, deducing the new solar terms, and so on. "】

[Xu Zi stood at the forefront, paused slightly, and pointed to the acres of land on the left and right. 】

[Qin Wang Yingzheng and Prince Fusu looked at the acres of land that had been reclaimed on both sides and were ready to be put into cultivation at any time, as well as the peasant children who were standing next to each piece of land, as if they were seriously recording something, and they also bowed slightly. 】

[Then Xu Zi continued to walk forward and introduced: "The front is the fertilizer group under the farming division, and there may be some peculiar smells. "】

["If Your Highness and Your Majesty find it unbearable, we can walk over quickly. "】

[Hearing this, Prince Fusu immediately frowned slightly and said, "Why is there a peculiar smell?"]

["Didn't the farmer children of the fertilizer group pay attention to keeping the environment clean and tidy according to the meaning of Lone?"]

[Although the prince Fusu can get closer to the people of Qianshou, so that he can walk between the fields and acres in the mud, and even accidentally step on the dung, his face will not change. 】

[However, this does not mean that Prince Fusu is a person who likes sloppy and peculiar smells. 】

[On the contrary, Prince Fusu is a person who likes cleanliness and tidiness very much. 】

[Therefore, Prince Fusu also made requirements for the six divisions, such as paying attention to keeping individuals and the environment clean and tidy. 】

[Even the six divisions of the crown prince will have special servants who are responsible for sprinkling and sweeping and cleaning up garbage every day. 】

[According to common sense, such a simple rule should be that no one in the six divisions will violate it. 】

[After all, there is no need for the officials of the six departments to sprinkle and clean up the garbage in person. 】

[Hearing this, Xu Zi also replied with some embarrassment: "Back to Your Highness, the farmer children of the fertilizer group have paid attention to keeping the environment clean and tidy in accordance with His Highness's requirements. "】

["It's just that the fertilizer studied by the farmers of the fertilizer group is not very clean and tidy, so it will inevitably have a slight odor. "】

[Hearing this, King Yingzheng of Qin on the side was also interested, and asked, "What do they use as fertilizer?"]

[Xu Zi was not embarrassed to answer directly, but replied euphemistically: "Your Majesty will know when you pass by the fertilizer group later. "】

[King Yingzheng of Qin raised his eyebrows, but he didn't continue to ask, anyway, as Xu Zi said, he will know when he passes by. 】

[Then after a while, when approaching the acres of cultivated land to which the fertilizer group belonged, Prince Fusu, Qin Wang Yingzheng and others smelled a peculiar smell from a distance. 】

[Of course, if it is a peculiar smell, it is a bit too elegant, to put it bluntly, it is the foul smell of feces or other unknown objects mixed after fermentation and brewing. 】

[However, although the smell is foul, the people present are not ordinary people.] 】

[King Yingzheng of Qin, who intends to annex the six countries and unify the world, has a broad mind and a firm will, which is far comparable to others. 】

[It's just a stench, for Qin Wang Yingzheng, it's not something that can't be tolerated. 】

[Prince Fusu, although he was born noble, he was able to lean down and listen to what the people of Qianshou said, and even walked among the muddy fields with the people of Qianshou. 】

[So although this foul smell dislikes Prince Fusu, for him, as long as it is necessary, then he can also endure it as a blind eye. 】

[And even the supreme status of Qin Wang Yingzheng and Prince Fusu did not express any dissatisfaction and disgust for this stench, so the officials and attendants under them did not dare to show their dislike. 】

[Yes, in the face of the foul smell that came to the face, everyone had no different color. 】

[And Xu Zi also introduced at the right time: "Before, His Royal Highness said that he wanted the children of the peasant family to find and study other fertilizers such as grass ash and rotting grass that can make the land fertile and increase yield. "】

["So, I and other peasant children began to study and verify this aspect. "】

["And the first thing that we think can also be used as fertilizer for acres of land is manure!"]

"A long time ago, I and other peasant children noticed that the crops on the acres of land irrigated with manure tended to grow stronger and more productive than those on the acres of land without manure. "】

["It's just that in the past, we were limited by various reasons and did not study it in depth. "】

["So this time, we have carried out in-depth research on the use of manure for farming. "】

["For example, manure and feces (urine), is it better to use manure as fertilizer for farming?"]

["Or is it better to use stool (urine) as fertilizer for farming?"]

["For example, human manure, horse manure, cow manure, dog manure, pig manure, etc., if you use it alone, which one has the best effect?"]

["If I mix them, will they be better than using them alone?"]

["For example, these feces are not diluted with water, and the effect of direct use is better?"]

["Or is it better to dilute it with water and then use it?"]

["For example, it is better to use these feces directly without drying them?"]

["Is it better to use it after drying it?"]

["Or is it better to mix it with soil and dry it before using it?"]

["In short, for every kind of manure that can be thought of for the time being, we have deliberately divided two acres of land for cultivation and comparative research, and strive to find out the best way to use these manures. "】

[Hearing Xu Zi's story, King Yingzheng of Qin, who had always been in front of Mount Tai and did not change color, couldn't help but change his face slightly. 】

[How filthy, dirty, and disgusting the feces are, he can do it in front of the feces without changing his face, but if he is allowed to take the initiative to study the feces, he will even be with the feces. . 】

[Then even King Yingzheng of Qin will never be able to do it!]

[However, these peasant children are able to study all kinds of manure in order to find the most suitable way to increase the yield of manure per acre of land, how noble is this!]

[At this moment, King Yingzheng of Qin looked at the peasant children who were studying manure around the fertilizer group, and his eyes were full of admiration. 】

[At the same time, King Yingzheng of Qin also looked at Xu Zi, and said with a solemn face: "Xu Qing and all the peasant children have worked hard!"]

[Xu Zi shook his head and said, "Your Majesty is serious, this is the responsibility of our peasant children!"]

[King Yingzheng of Qin also shook his head and said: "This is the responsibility that the children of the peasant family think they should do, but they are working hard to increase the grain production of the people of our Qin State. "】

["The Qin State is not a country that is not rewarded for merit, and the widow can make a promise to you here. "】

["When the children of the peasant family have developed the most effective way to use manure to increase the yield of crops, the widow will surely bestow knighthoods on those who have contributed the most!"]

["In addition, all the farmer children of the fertilizer group will be rewarded with 10 catties of meat and 10 stones of polished rice as encouragement!"]

["Zhao Gao, go back and receive the widow's edict to go to Shaofu to withdraw it. "】

[Zhao Gao, who was behind King Yingzheng of Qin, immediately bowed down and responded: "Yes, Your Majesty!"

[Xu Zi also bowed to King Yingzheng of Qin and said: "The farmer's children of the fertilizer group of the ministers, thank Your Majesty for your promise and reward!"]

[After Xu Zi got up, Prince Fusu also spoke: "The children of the farmers in the fertilizer group are commendable, but we must pay attention to washing hands, bathing, and changing clothes after each study. "】

["Zhang Han, go back and give ten sets of new clothes to each of the farmer children in the fertilizer group!"]

["In addition, the children of the farmers in the fertilizer group should also cover their mouths and noses with strips of cloth as much as possible when they are studying. "】

["After all, feces are inevitably filthy after all, and if there is no barrier to contact, I am afraid that I will get sick because of it. "】

[Zhang Han, who was behind the crown prince Fusu, immediately replied: "Yes, Your Highness!"

[Xu Zi also bowed down to the prince Fusu and thanked him: "The children of the farmer family of the fertilizer group of the ministers, thank Your Highness for the reward!"]

[Then everyone walked past the peasant children studying the dung on the left and right, and the prince Fusu saw a group of peasant children in front of him who were spreading some black mud-like unknown objects on the fields and asked, "What are they laying out?"

[Xu Zi glanced at it and immediately replied: "Those are the silt at the bottom of the river. "】

["In addition to the manure just mentioned, the second thing that my peasant children think can be used as fertilizer for the acres of land is silt. "】

["Because after the canal in Guanzhong was dug well, the grain yield per mu in Guanzhong increased greatly. "】

["So in the past six months, I and other peasant children have also carefully observed and studied the canal in Guanzhong on 3.8. "】

["Then we found that the acres of land on the left and right sides of the Guanzhong Canal were more productive than the acres of land not close to the Guanzhong Canal. "】

["But the acres of land near the Guanzhong Canal and those not close to the Guanzhong Canal are basically the same acres of land, and the same river water from the Guanzhong Canal is irrigated. "】

["Logically speaking, there should be no difference between the two acres of land, but why is there a clear difference in the yield of grain per mu?"]

["So after carefully inquiring about some of the local people who were in charge of digging the canal in Guanzhong at that time, we found one thing. "】

["That is, when digging the Guanzhong channel, in order to save labor and convenience, those conscripts will pour the excavated river silt directly into the acres of land on the left and right sides. "】

Then we thought that if we buried the decaying weeds in the fields, we could make the land fertile and increase the grain production. "】

["And the silt at the bottom of the river has been hidden in the bottom of the river for many years, and how many things have rotted silently in it?"]

"So the silt at the bottom of the river should also be as good a fertilizer as rotting weeds. "】

So they went and dug up some silt from the bottom of the Pei River, and the silt from the pond of Niushou Pond. "】

"I'm going to make this sludge into a kind of fertilizer to see if it can really make the land fertile and the food more productive. "】.
