Zheng Lizheng was particularly concerned about improving the wasteland, Wei Renshi only told him how to prepare before last night, and the next morning Zheng Lizheng hired someone to build a fence.

Wei Renshi woke up early in the morning, and the meal had already been cooked, and the two of them got up.

As soon as he went out, Lin Sumian smiled at Wei Renshi and said, "Wei Langjun is really a good skill, yesterday's wine was the strongest I have ever drunk in my life, but I woke up today without a headache!" ”

Liu Yuxi also spoke: "I drank Wei Langjun's wine yesterday, but I'm afraid that the wine next to me will no longer be able to taste in the future." ”

Wei Renshi smiled and said, "This is simple, and soon this wine will be available in Luoyang City." Maybe it will be available in Chang'an in the future. ”

As Wei Renshi spoke, he took out a few pieces of paper and handed them to Liu Yuxi.

Liu Yuxi stretched out his hand to take it, looked down, and immediately showed surprise, and said, "This ...... This is...... Plough pattern! ”

"Not bad." Wei Renshi nodded and said, "After Master Liu goes back, let people build it according to the pattern, and then assemble it into a plow." ”

"Master Liu, can you let me take a look at it next?" Lin Sumian said eagerly on the side.

Liu Yuxi looked at Wei Renshi, and Wei Renshi nodded. Liu Yuxi gave him the pattern.

Lin Sumian looked at the pattern on the side, and Liu Yuxi asked, "Is this ...... Wei Langjun gave me the pattern, but I don't know what the price is? ”

Wei Renshi thought for a while and said with a smile: "Then invite me to have a meal!" ”

Liu Yuxi was stunned and said, "Wei Langjun is noble! ”

"Wonderful! Wonderful! Over there, Lin Sumian slapped his thigh, made a sound, and said, "How did Wei Langjun think of changing to a plough as well?" ”

Wei Renshi looked at him and said, "Practice makes true knowledge." Only in practice can we know what kind of tools are needed, and in the process of use, we will find the shortcomings of the tools, and then improve and improve. ”

Lin Sumian looked excited, got up and said, "I'm even more looking forward to seeing the mechanism that doesn't need to be watered by anyone!" ”

"Let's see, then." Wei Renshi said.

led the two out of the door, Wei Renshi walked all the way, explaining to Lin Sumian all the way. From the bamboo pipe at the head of the ground, to the reservoir on the back slope, and then to the water turning and overturning by the Daoyuan River, Lin Sumian and Liu Yuxi all looked at it carefully.

"Wei Langjun's talent is really amazing to a certain family." After visiting this simple drip irrigation system, Liu Yuxi sighed: "In the land of plains and rivers, all can follow this method, and the people will benefit greatly." Well...... The land of Weinan is like a green tile, with a flat river in the middle, or it may be irrigated in this way. However, on both sides of the plateau, this method is not feasible. ”

"Farming pays attention to adapting to local conditions. The situation in Changgu is different from that in Weinan, and this method is naturally different. Wei Renshi said with a smile: "If Master Liu wants the people of Weinan to grow good food, it is better to teach them to dam and silt the land. ”

"Damming the silt?" Liu Yuxi asked suspiciously: "But what is the method?" ”

Wei Renshi said with a smile as he walked: "If I remember correctly, there should be no shortage of water in Weinan. The big river alone has three crossings: the Yellow River, the Wei River, and the Luo River. Not to mention that there are other thousand rivers, lacquered rivers, and so on. ”

"Not bad." Liu Yuxi nodded and said, "Wei Langjun really hasn't been to Weinan?" However, drought and autumn floods are the great enemies of Weinan farming. ”

"The water of the Wei River is mixed with a lot of sediment, yes or no?" Wei Renshi asked, and his mind was also quickly recalling the information about the Wei River.

It seems that it began in the Eastern Han Dynasty that the "river" became the "Yellow River".

As early as the Spring and Autumn Period, there were written records that the Yellow River was not clear.

In "Zuo Biography", Zheng Guo's Zisi quoted "Yi Zhou Poems" and said: "The clear of the river, the life expectancy is geometric!" It can be seen that the Yellow River is not clear and has long been known.

In the middle of the former Han Dynasty, Jingshui was famous for its turbidity currents. In the time of Emperor Wu of the Han Dynasty, "Jingshui is a stone, and its mud is several buckets".

The Wei River is the largest tributary of the Yellow River, and the Jing River is the largest tributary of the Wei River. The Jingshui and Weishui basins are the earliest areas for agricultural development on the Loess Plateau.

With this development, the original vegetation was destroyed, and the soil erosion increased, causing the river to become more and more turbid, and probably developed into a conspicuous situation in the Eastern Han Dynasty, thus giving it the name of "Yellow River".

Liu Yuxi nodded: "Not bad." ”

Wei Renshi was relieved, he remembered that the Yellow River had begun to carry sediment at a very early stage, especially in the Wei River and Jing River basins.

"River mud is a good thing!" Wei Renshi said to Liu Yuxi: "Master Liu, the river mud is fertile, and it is the best for farming. ”

Liu Yuxi stared at Wei Renshi: "Wei Langjun means ......"

"That's what I'm talking about damming silt." Wei Renshi smiled and said, "Let me sell it, let's go to a place first." ”

Liu Yuxi was in a hurry, and his steps immediately became three points faster.

After walking for almost half an hour, Wei Renshi took the two of them onto the official road, and walked along the official road for nearly half an hour, and finally saw the pavilion.

Because it is close to Luoyang City, there are a lot of people on the official road from Fuchang. Naturally, there are a lot of people in the pavilion.

Wei Renshi walked in and saw one of the running halls at a glance. He is extremely tall, estimated to be more than 1.8 meters tall, and he is very conspicuous inside. That's why Wei Renshi recognized him at a glance when he went in - Sun Laohan's nephew.

Wei Renshi found an empty table close to him and sat down, and Sun Laohan's nephew immediately ran over.

"A few guest officers came at the right time, this is noon, I'm afraid I'm thirsty and hungry." Sun Laohan's nephew said with a smile, set the bowl, poured water into it, and said: "A few people drink saliva to moisten their throats first, the old well behind our pavilion is cold, it is very antipyretic and thirst-quenching!" ”

"Thank you." Wei Renshi smiled and said.

Sun Laohan's nephew took advantage of the time when Wei Renshi and a few people were drinking water, turned around and asked a few people at the next table who had just drunk water and put down the bowl, "What do you want to eat?" The food in our inn is full and delicious. How do you eat it? ”

"Hmm...... The rough man who runs away, as long as he can manage his fill, what are the things? One of them said.

"Okay!" Sun Laohan's nephew smiled and reported a few names, and those people ordered a few things respectively.

After they finished ordering, Wei Renshi's side also drank the water. He came back and asked, "How do you eat?" The little one will give you a name? ”

"Okay." Wei Renshi nodded.

He put a few more names out of his mouth, but they didn't sound the same as they had just reported.

"This meal was invited by Wei Langjun, and Wei Langjun just ordered it." Liu Yuxi said.

"Master Liu, don't rob it!" Lin Sumian smiled and said, "My trip to follow Wei Langjun is an eye-opener. The pots and kitchen utensils in the stove, the objects of the people sitting in the hall, and the table that can be turned in the middle...... The plough, the watering mechanism, and the overturned cart...... That's enough for me to go back and think about it for a long time. It's time for me to invite Wei Langjun. ”

"Report the food first, and then talk about it after eating." Liu Yuxi smiled.

Wei Renshi ordered a few casually, and Sun Laohan's nephew ran to the back to report the food.

"It's a lot of fun." Wei Renshi said.

"The table was not rich at first glance, so he gave him cheap and satisfying meals. Come to our table, and the ones that will be reported are the more expensive. Lin Sumian smiled: "I can take care of the guests, and I have a little bit of eyes." ”

"Wei Langjun, you don't care about this running hall for now. Even if you come to see him, wait until you finish telling him what is damming and silting! Liu Yuxi said hurriedly on the side.
