Jingwen saw this straight plough and cocoon, and immediately knew that there were still many improvements in ancient agricultural tools. For example, Jingwen has seen in the middle school textbooks of later generations that the ancient plough was used to plough the field, and even in the 21st century, the Quyuan plow was still used. At most, later generations turned manpower and animal power into agricultural machinery to pull, but for Quyuan plow, his principle has not changed. Therefore, Jingwen quickly thought of "inventing" the Quyuan plow, which has great benefits for agricultural development.

Jingwen said that he would move, and first let these craftsmen quickly build the Quyuan plow, and the most important part of the Quyuan plough is that the wheel is curved, and the others are similar to the straight plow. However, because this wheel is curved, various mechanical principles can be well applied and a lot of effort can be saved. In the past, the plough was pulled directly, but the straight plough was not only laborious, but also not deep enough. The curved plough makes use of the lever principle, and can plough deeper, and the efficiency of ploughing is faster.

And this curved system is also simple, in fact, it is just that the wood can be bent when it is wet, and then it becomes a curved after it is dried. And Qu Yuan plough is just a matter of thinking, not a matter of advanced technology, so Jingwen can easily figure it out.

"My lord, now let's go to Sinong Temple and let them allocate a piece of land belonging to the imperial court to try!" The technician said.

Soon, Jingwen came to Sinong Temple, and then used a piece of land. These lands belonged to the imperial court and were used to grow royal tribute. The tributes eaten by the emperor were all directly planted by Sinong Temple, because the planting was directly responsible for these officials, and the imperial court could rest assured. As for those who pay tribute from outside, that is, they just select some fine things to pay tribute.

"Your Excellency, are you here? Also brought this thing? The official of Sinong Temple asked.

"Yes, I'm coming, I'm going to try this zigzag plow I invented!" Jingwen said.

"Okay, okay. Now we are just preparing for spring planting, and now winter is also ready to pass. Seeing that it will be spring in a few months, the land is idle at this time, so as long as you need it, we can provide it to you to lend it to you! The official of Sinong Temple replied.

After all, the land is idle now, and there is still a month or two before the spring planting, and the land is empty. So since Jingwen wants to borrow it, there is no problem at all, after all, they don't dare to offend Jingwen. And if Jingwen invented this Quyuan plow, it would also be good for Sinong Temple. Sinong Temple is responsible for the world's agriculture. If agriculture develops, then they will be able to make progress! Since Jingwen wants to be a real farming tool, then it is good to give Jingwen a real yàn. And this can also please Jingwen, so why oppose it?

"Quack!"

Jingwen stepped on this land, and it felt relatively hard, and he didn't know if he could turn it over.

"My lord, it's still cold, so let's see if this plow can plow the ground! Generally speaking, we wait until the spring when the ground is relatively soft, and then we use the plough to plow. And now my lord, you use this curved plough to plow the ground, is there a problem with this? The official of Sinong Temple asked.

"No problem! Simple! Look at me! Get the ploughing ox right away. I'm going to watch you plow! Jingwen said.

Soon, a farmer hired by Si Nong Monastery immediately began to plow the land. At first, the farmer didn't know how to use the plow, but under Jingwen's teaching, they soon became familiar with the use of the plow. Then. Jingwen looked at the peasants who were plowing the fields.

And the speed at which he ploughed the ground seemed to be no different from the past, and Jingwen was also a little puzzled. Did your invention fail?

After a while, the farmer finally ploughed the field. He came to the officials of Sinong Monastery and said, "My lord, this plow is so good, it is really good. If you use this plow. I'm afraid the speed of turning the ground is at least several times faster! ”

"Oh? It didn't seem to be much faster than the straight plow just now! Jingwen asked.

"My lord, don't you know, the ground is actually very hard now, so it can be at the same speed as in the past, which means that the actual speed is several times faster than the straight plow in the past. Moreover, this curved plough is obviously very labor-saving, and you can see that he did not seem to have to make much effort to turn over the land. And this is a land in cold times, so it is difficult to turn, so in fact, it is very labor-saving. The official of Sinong Temple said.

Jingwen then remembered that the land in winter was completely different from spring. In winter, the land is frozen soil, but in spring and summer, the ice in the land melts, so it becomes much looser than in winter. And this curved plough can plow the ground in winter, which already shows his ability, and it can be very labor-saving.

As for this Si Nong Temple official, he immediately said: "This Quyuan plow is not simple, if we can use this Quyuan plow, then our Datang now has fewer people and more land, and the situation will be improved." Now a lot of land is idle and deserted. If there is this zigzag plough, then I am afraid that many people will be able to plant more land, so that more land can be planted and harvested. ”

It was the beginning of the Tang Dynasty, and it was still a time when there were fewer people and more land, and the population had not yet been able to swell. Therefore, now we are trying to improve the people's utilization rate of land, but now everyone's physical fitness is like this, and it is impossible to improve the utilization rate of land by much. And if there is this quyuan plow, then the people can use the same body to cultivate more land, so that for the people, it is increasing production and income, and the court can also increase taxes! If the land can be expanded, it will also help to reduce the burden on the people. If the more land is cultivated, the average pressure on each peasant household will be reduced.

"Lord Jingwen, we will accept this quyuan plow, thank you Lord Jingwen!" And the official of the Sinong Temple immediately said.

But Jingwen immediately said: "Don't worry, I have another thing that can open your eyes!" This is something that can be sown, and it can greatly improve the efficiency of sowing! ”

"Sowing? Isn't it always time to use cocoon for sowing? The official of Sinong Temple asked.

And Jingwen immediately asked the craftsman to take out a seeder, and this made the official of Sinong Temple a little surprised, and he didn't know what this thing was. (To be continued......)
