Deng Ai happily raised his hands and said: "Thank you so much, General. In this way, I only need to give you two years to connect all the newly built canals with those originally built by the Wei Dynasty. p>
This, it will be very convenient whether it is transporting grain, grass or troops!"
Before they knew it, everyone had arrived at the gate of the county governor's house despite the scorching heat of Jingzhou's afternoon heat, and were about to leave. Cao Shuang held the reins in one hand.
Freeing up his other hand, he casually wiped the sweat on his forehead that was burned by the hot sun with his sleeve, and said with a smile: "Gentlemen, the weather is so hot today, let's go back and rest first."
/p>
However, we must also give instructions. In addition to the remaining standing troops, we must all prepare. When the troops return to the court in a few days, we will go to Luoyang together. After the military parade, everyone will be rewarded!"
All the generals happily said in unison: "Thank you, General!"
They all rode their horses back to rest. After all, the weather was unbearably hot. Deng Ai also wanted to follow the others and leave to go to the county governor's temporary residence to take care of Nanjun affairs.
Cao Shuang smiled and said: "Shizai, don't leave in a hurry. I still have something to discuss with you. Come on, come with me into the government. After discussing things, it's not too late to go back to handle government affairs!"
Deng Ai said: "The last general will obey the general's order!"
The two handed the horses over to the groom who had already been waiting at the gate of the mansion. They took the horses down to take care of them, and then went straight into the mansion to the meeting hall...
When the two of them sat down in the meeting hall, a servant of the mansion had already placed the ice mirror in the hall. The air-conditioning continued to fill the spacious meeting hall, making the two people who had just quickly entered the room suddenly feel a sense of warmth.
A cool feeling.
Cao Shuang said: "I want to take the lead in forcing the introduction of composting in the five counties to increase food output. What do you think?"
Deng Ai looked troubled and said: "General, this method of composting is indeed effective. It can increase food output and improve the fertility of the land.
I have used it in Huainan before, but very few people are willing and willing to spend time doing this in their spare time. After all, if you have the time, it would be better to open up a few more acres of wasteland."
Cao Shuang said with a smile: "I didn't ask them to voluntarily pile manure, but to force this to happen. After all, some military camps will be placed here in the future, not only to provide more food, but also to prevent the Wu army from attacking.
”
Deng Ai took a sip and said, "No, I wonder if the general has a better method of composting and can he teach these soldiers how to use it?"
Cao Shuang thought for a while and said: "The best composting method I have is the retting method."
Deng Ai asked in confusion: "General, what is the method of fertilization?"
Cao Shuang said with a smile: "Retting fertilizer is actually very simple. Plant stalks, green manure, weeds, etc. are placed in the water collection pit with river, pond mud and human excrement, and the fertilizer is fermented.
Retting fertilizer can be divided into two types: cod fertilizer and grass pond mud. Cog fertilizer can be accumulated at any time, while grass pond mud can be accumulated in winter and spring.
Caotang mud is made of human and animal excrement, weeds and leaves. As you can see from the name, Caotang mud is made of human and animal excrement and river and pond mud.
Both types can be composted in the open air. They can be turned into fertilizer in two to three months in winter and can be put into use in the early spring of the next year.
It is already July, and it is too late to use this fertilizer this year. However, you can make it in winter and save it for use in early spring next year. You will be able to witness its effect in increasing production in next autumn!"
Deng Ai said happily: "The general will give in tomorrow and let people promulgate the compulsory composting order of the general!"
Cao Shuang thought for a while and said: "After I returned to Luoyang, I ordered people to ask Ma Jun to build some new iron pears for the five counties in Jiangbei under the control of Shi Zai to use them first. I believe they will be very good.
It saves manpower and animal power in farming!"
When Cao Shuang thought about the composting method of later generations, he thought of the Quyuan plow, a sharp farming tool...
As a result, this pear, which originally appeared in the late Tang Dynasty, appeared four to five hundred years earlier in history.
The plow has basically been finalized in the Han Dynasty, but the plow in the Han Dynasty was a long straight shaft plow. It was not flexible enough to turn back and turn when plowing, and it was laborious to lift the soil and the efficiency was not very high.
The "Qi Min Yao Shu" written by Jia Sixie of the Northern Wei Dynasty mentions the long curved shaft plow and the "Weili", but due to unclear records, we can only speculate that they are short shaft plows; in the early Tang Dynasty, the long curved shaft plow further appeared.
The advent of the flexible "Weili" and the emergence of the long curved shaft plow laid the foundation for the final formation of the Jiangdong plow. Its advantages are that the plow body can swing during operation, which is highly maneuverable and convenient for deep plowing, and is light and flexible, which is conducive to maneuvering.
, suitable for the small paddy field area in the Jiangnan area, so the short curved shaft plow first appeared in the Jiangdong area.
The second is to add the plow and plow construction. If you push the plow forward, you can make the plow arrow downwards and the plowshare will penetrate into the soil deeply. If you lift the plow, make the plow arrow upward and the plowshare will penetrate into the soil shallowly.
The organic combination of the plow shaft, plow arrows and plow construction of the curved shaft plow can adapt to the different requirements of deep or shallow plowing, and can standardize the depth of cultivated land to facilitate intensive farming.
The plow wall can not only break up the soil, but also push the plowed soil to one side, reducing the resistance of the plow. The curved shaft plow has a complete structure, is light and labor-saving, and is an advanced plow at that time.
Through the Song, Yuan, Ming and Qing dynasties, the structure of the plow has not changed significantly, which shows its advanced nature.
Deng Ai said with some expectation: "General, I heard you say that the new iron pear can save manpower and animal power, and the new iron pear is also made by a great craftsman like Ma Jun.
The general is really looking forward to the new iron pear made by Ma Jun. After all, Ma Jun is Luban of the time, and every thing he has made before is extraordinary!"
When Ma Jun was young, his family was poor, and he had a stuttering problem with Deng Ai, so he was not good at speaking but good at thinking. Later, he served as an official in the state of Wei.
Before that, Ma Jun restored the compass wheel, improved the cumbersome silk weaving machine at that time, and invented a keel waterwheel that diverted water from low areas to high areas. Although his reputation gradually became more and more prominent in the Wei Dynasty, he was not taken seriously by the nobles of the Wei Dynasty. Of course,
This also includes the former Cao Shuang.
But today's Cao Shuang is no longer the Shuang who sees "nearly", but the Shuang who sees far away,
How can we not pay attention to such a talent? He plans to reuse such a great talent after returning to Luoyang. For Cao Shuang, it would be a waste of resources to use such a great talent.
After Cao Shuang finished giving these instructions, he thought carefully that there was nothing else serious to do today, so he asked Deng Ai to go back and rest first.
Ma Jun, who was far away in Luoyang, was still immersed in inventions and creations in his small courtyard on the outskirts of Luoyang City. What he didn't expect was that because of Cao Shuang's attention, his fate, which had been ignored before, would be drastically changed. At the same time, on the way from Luoyang to Jingzhou, more than ten riders were riding fast horses to Jingzhou...
