"Zhiyuan, the plow you served at the ploughing ceremony today is good, much more advanced than the long straight plough that the old man saw in the Central Plains......."
Don't look at Lao Du from a family like Jingzhao Du, but he is not a parasite who is not diligent in his limbs and grains, for farm work and farm tools, Lao Du can be regarded as a good hand, otherwise when Li Lu helped the plow, he would have seen that Li Lu's plow was much better than the plow in the Central Plains."
Du Xiang, do you still know this?"
Seeing that Lao Du actually knew how to use farm tools, Li Lu was surprised, "Zhiyuan, what kind of eyes do you look at the old man?"
Let me tell you, every spring, His Majesty leads hundreds of civil and military officials to personally go to the land to farm, even old men like Kong Yingda have to go to the ground......
How could the old man not understand farm tools?
”Lao Du said with some dissatisfaction."
Oh, I know, Du Xiang, the plow you said, its name is Quyuan Plow......."
Li Lu said with a smile, "Quyuan Plow?"
This name is really imaginable......"
Lao Du said, "Zhiyuan, is your plough improved on the basis of the Changquyuan plough and the Wei plough recorded in Nongsheng Jia Siyi's "Qi Min Yaoshu"?
”"Awesome, Du Xiang!
Our Jiankun people used to use the long straight plough you said, a use of hundreds of years, after my master came to Xiling, saw this long straight plough when the plough turned back and turned not flexible enough, the soil is laborious, the efficiency is not very high; After passing through hundreds of workers, he made improvements on the basis of the long Quyuan plough and the Wei plough recorded in Jia Shengshu, which led to the birth of the Quyuan plough.......
"Li Lu put the name of the Quyuan plough on the master who had nothing to do.The zigzag plough made by Li Lu is of great significance in the history of Chinese agriculture.He grew up in a mountain village in the northeast since he was a child, and he is no stranger to the Quyuan plow, Li Lu followed his grandfather when he was a child in his previous life, and his grandfather supported the plow alone, and the old ox mooed in front of the plow, which is a situation that Li Lu will never forget in his memory.Quyuan plow, in the original history, should have appeared from the end of the Tang Dynasty, and then quickly swept the entire land of China, until the Qing Dynasty and even in the 21st century in some poor places in China can still see its figure, Li Lu lived in the mountains of the small mountain village when he was young, the tractor could not plow, can only be ploughed by this Quyuan plow......
The most amazing thing is that since the appearance of this curved plough until it was completely replaced by mechanization, its shape and structure have hardly changed much, except that the material has become better and more durable with time and technological progress.It was precisely because Lao Du knew the way of farming that he could see at a glance the extraordinaryness of the curved plough that Li Lu pretended to be made by his master.When Li Lu supported the plow, Lao Du found that the plough frame is small and light, very convenient for turning and turning, which can greatly save the effort spent by people and livestock when plowing the field, which saves time and saves strength and time, so how much wasteland can be reclaimed, how much food can be fed, and how much population can be fed!
When Li Lu took Lao Du to see the Quyuan plough closely, Lao Du found that the Quyuan plough was composed of eleven parts: ploughshare, plough wall, plough bottom, pressure plate, strategy, plow arrow, plow wheel, plow tip, plow evaluation, plow building and plow plate.Moreover, after Lao Du personally experimented, he found that as long as the three parts of the plough evaluation, plough arrow and plough construction in the Quyuan plough can be operated properly, then it can be both deep ploughing and shallow ploughing, which is perfectly adapted to different cultivated land conditions such as upper field, middle field and lower field, which is convenient for farmers to carry out intensive cultivation."
Zhiyuan, the old man asked you, if the old man wants the drawings of this Quyuan plow, will you give it?"
Lao Du Don't look at Li Lu's state minister, but his heart is not here in Li Lu, he is Li Er's confidant and cronies, and he once worshiped the prime minister of the Tang Dynasty, he understands the role of this Quyuan plow, so he has this begging words."
Huh?
Drawings of this curved plow?
Du Xiang, are you asking for it for the magnates of Chang'an, or for the people of the Tang Dynasty?
”Li Lu asked suddenly.Lao Du heard Li Lu suddenly ask such a question, he was stunned for a moment and then said, "It's all, it's not entirely right to say that it is for the people of the Tang Dynasty, after all, the old man is from Du Ling's .......""
Hehehe, Du Xiang is a sincere person, this drawing, no problem!"
Li Lu said with a smile, "Du Xiang, I'll let you go and see how the Han people here in our Jiankun ..... cultivate" Li Lu and Lao Du rode horses to the farmland outside the Broken Leaf City, only to see that some farmers were ploughing, some were fertilizing, and some were irrigating, Lao Du Wei could also see such a busy farming scene outside the plug and was very emotional, "Zhiyuan, the old man looks at this place in the river, although it is not as good as Guanzhong, but it can also be regarded as Zhongtian......"
Lao Du rode on the horse and asked Li Lu, "Why do you want to cover this black mud in the field, um, This black mud stinks.......""
Hahaha, Du Xiang, this is manure, it's strange if it doesn't stink......
Li Lu explained to Lao Du with a smile, "Du Xiang, you just said that the good land in this river is just equivalent to the middle field in Guanzhong, in order to increase fertility, the masters of Daomen have studied this composting method after many experiments......"
How to compost?
Zhiyuan, your composting method uses cow dung?
”Lao Du asked."
No, this is horse manure, sheep manure and human manure mixed in a certain proportion and then made."
Li Lu explained the formula, "Cow dung can be used as fuel, and it will be used as fertilizer to fertilize the field after burning......
"Manure was originally used on a large scale in history until the Southern Song Dynasty.Lao Du is a smart man, and he knows very well that fertilizer, a freshly baked thing, plays an extremely important role in maintaining the fertility of farmland.Generally speaking, as long as the land can be cultivated, the soil is fertile, and the land without fertility cannot grow crops.But anyone with a little insight knows that this fertility of the land will begin to decline after a few years or even a year or two of cultivation, even in the so-called Ueda.There is a description of this situation in the Chinese classic "Book of Rites": "If the soil is poor, the grass and trees will not grow, and if the qi fails, the creatures will not fail." ”。
The direct consequence of the loss of soil fertility is, of course, a reduction in crop yields and crop yields, which is obviously unacceptable to farmers.Reduced production means starvation, and even starvation.Therefore, in order to preserve the fertility of the land, farmers can only use extremely simple and primitive methods such as fallow and rotational tillage, or two crops in three years, or one season of wheat chestnuts and one season of beans.Lao Du knew this situation, in Guanzhong, the people widely used fallow, rotation to maintain or restore the fertility of the land, until he followed Li Lu to the Western Regions, only to discover that manure can maintain or even increase the fertility of the land.Li Lu took the old Du Guan to see the stinky manure, but not Li Lu's invention, this is the Chinese working people in the long-term production and labor of the effective measures, of course, it actually appeared more than 400 years later than now in the early years of the Southern Song Dynasty will be used on a large scale, the late Ming Dynasty and early Qing Dynasty agronomist Zhang Luxiang wrote the "Book of Supplementing Agriculture" on the record: "The dung of people and animals and the ash of the stove are useless."
As soon as it enters the field, it will be turned into cloth and corn corn. ”Later, a common saying circulated among the common people made it clear: "A crop is a flower, and it all depends on dung."
Therefore, manure is very important for Li Lu, who occupies a barren land, because at present, he can't toss three acids and two alkalis, and he can't establish a modern chemical industry, so he can't produce chemical fertilizers, so he can only rely on these soil fertilizers.......
When Li Lu and Lao Du walked to a field far away from the Chu River, Lao Du found that there were ditches in the square fields so far away, and these ditches were covered with stone slabs, "Zhiyuan, where does the water come from to irrigate this field?"
”Lao Du walked to the field, personally inspected the river water in the ditch, and then said."
Naturally......, it was drawn from the Chu River," Li Lu said with a smile, "These ditches were all built by the Sogdians, but the previous Turkic barbarians would not use them, so they were abandoned......."
If it's a field higher than the Chu River, what will you do?"
Lao Du asked, he wanted to know how advanced the agricultural equipment of this Jiankun was, "Hehehe, Du Xiang, you ....... look" Li Lu was happy when he heard this, he pointed with his hand, Lao Du looked, hey, by a pond connected to the Chu River, a waterwheel that was completely different from the cylinder car in the Central Plains was constantly drawing water from the pond by the pond......"
Whoa!"
On one side of the waterwheel, two big green donkeys are pushing gears like a grinder, and with each turn of the donkey, a large amount of water is drawn out of the pond.The outlet of the waterwheel is flowing non-stop, and the rushing water flows into the ditch that is much higher than the pond, and the water source of the Chu River from here flows continuously into the distance."
That's a lot of water!"
Du Ruhui came to see it and couldn't help but marvel.Compared with the traditional cylinder car in the Central Plains, the water output of the hydraulic dump truck standing on the bank of the Chu River in the Western Regions is much larger, which also means that the efficiency of irrigation is much higher.Quyuan plow, composting method, water conservancy overturn, these are all good things that can increase grain production!

Looking at Lao Du's envious, jealous and hateful expression, Li Lule was happy, Lao Du, you see that these are all strange tricks in the eyes of your Confucianism, but they can increase grain production, do you think this is a slap in the face?"
Hehehe, Du Xiang, this is the power of technology that I once told you!
If the people want to increase production, they can't do without the strange tricks and tricks in the mouths of Old Man Kong and Old Man Wen......."
Li Lu sneered, "In my Jiankun Kingdom, there is no such thing as this strange trick and trick, you see, I call them science and technology to rejuvenate agriculture......"
Li Lu's words sounded very harsh to Du Ruhui, but Lao Du also had to admit that Li Lu was telling the truth........
