Then we saw a seeder, this seeder is different from the old cocoon, although there is a furrow opener under it that is the same as the cocoon, but there are two wheels next to the furrower. And this wheel clearly seems to have a gearing. As for the above, although there is also a funnel, it is only put in by manpower. And this kind of cocoon, his "automation" is very poorly done. Because once the seeds are put in, they have to be sown continuously, and once they stop, the seeds will continue to fall, wasting the seeds.

When manpower and animal power are tired, once they are tired, the speed will slow down, so that the seeds continue to fall, which may cause a large increase in the density of seeds in local places, which is not good for balanced planting. Therefore, this cocoon is not suitable for much worse than the later seeding machine. As for this cocoon, it also does not have the function of covering soil, so the effect is much worse than that of the later strip-seeding type seeder. Therefore, Jingwen invented a strip-seeding planter, which is probably much better than this kind of seeding.

"You see, I invented this seeder, which is very similar to the furrower of the cocoon. But you see this wheel, and this wheel moves the springs in it as we go, and then it leaks the seeds step by step. And we only leak seeds when we are on the road, and once we stop, we don't continue to leak seeds. This tube can be selected for thickness, and seeds with different densities can be selected. And there are things that can be used to cover the soil, and you see that this one can also be used to cover the soil. So, as long as you have this thing, sowing is no longer a problem. Jingwen said.

And suddenly someone asked, "What is this spring made of?" What is it made of? This thing seems to be good, if nothing else, I'm afraid it can be used in many places. But what exactly is this made of? ”

"Hehe, after the spring is pressed, he will recover by himself after releasing it. I made this zuò from the kind of steel used in a soft sword. This is a good thing, and I use it to make springs. I didn't expect to be able to produce springs. And also because of this spring. so that my seeder can be realized. Jingwen said.

Just now, when Jingwen was making a zuò seeder, he suddenly realized an important problem, that is, the problem of springs. In Jingwen's understanding, there were no springs in ancient times, because springs needed spring steel to make zuò. But when Jingwen had a headache, a sword-making technician took the initiative to take out a kind of steel, which made Jingwen overjoyed. Because this steel is soft, flexible and elastic. Jingwen immediately asked what this thing was, and the technician immediately replied that it was soft steel used to make a soft sword.

Jingwen saw the so-called soft sword. I also remembered the martial arts TV series in later TV, where there were often some swordsmen holding soft swords that were as thin as paper and as flexible as springs. And Jingwen thought it was impossible at first, but later heard the words of this sword craftsman, this kind of soft sword actually existed as early as the Eastern Jin Dynasty, and there was a poet who made a poem specifically for the soft sword. Although this kind of soft sword is more biased, it is also stored after all. This is enough to show that in ancient times, there was actually zài soft steel, and this kind of soft steel is actually spring steel, which can be used to make zuò springs.

Jingwen saw this scene. This kind of soft steel was immediately used to make zuò springs, although this spring was relatively rough, but it was actually enough to bear the needs of such a primitive tool. And the problem of springs is solved, and the subsequent invention is very easy. And this kind of strip seeder. In fact, it was invented by a musician in the West, and it has to be said that it is a irony. However, since this kind of thing is a foreign devil, Jingwen will bring it when he takes it, and he has no idea of taking care of other people's scientific innovation.

"Look at it. This is a complete reduction in seed waste. Usually at least two liters of seeds are needed for an acre of land, but with this seeder, intensive cultivation has been achieved. You can save seeds, so that you can use a liter of more seeds per acre of land. So, as you can see, we're increasing production. In the future, we can continue to improve the agricultural tools, so that we can continue to increase the yield. Jingwen said.

And Jingwen's previous farming level is actually extensive planting. Before the Tang Dynasty, and even at the beginning of the Tang Dynasty, agricultural cultivation was very extensive, and there was not much elaborate management. Now, Jingwentong guò these agricultural tools hope to change the thinking of the Tang Dynasty peasants, so that they can intensively cultivate the land. Because of the perfect agricultural tools, and now that the Turks have been defeated, the cattle and horses on the grassland can also come to the Central Plains, which can help the people to plant land, so there is no shortage of cattle for the time being. Next, it's time to take care of the land so that they can work intensively and increase their food production.

"Good stuff, good stuff, really good stuff! Lord Jingwen is really knowledgeable, and Lord Jingwen's seeder and Quyuan plough can be no less than Jia Sixian's Qi Min technique. It seems that it may not be long before Lord Jingwen will be able to obtain the title of a farmer! The official of Sinong Temple immediately touted.

Obviously, this kind of boasting doesn't need money, and anyone can open their mouths to brag about it. Anyway, as long as Jingwen is fooled, then Si Nong Temple and the Ministry of Industry can produce the production of this seeder and Quyuan plough together, which is very helpful for farmers.

"Lord Jingwen, on behalf of the farmers in the world, I would like to express my gratitude to you. And now there are still a few months before the spring ploughing, if we hurry up now, then maybe the people near our Chang'an can use this kind of curved plough and seeding machine in this year's spring ploughing, so that we can usher in a bumper harvest in the Guanzhong area of Chang'an, and it will not be long before we can usher in a bumper harvest. And when the time comes, more land will be cultivated, and then my Datang's grain will be able to increase a lot of production. In this way, everyone in my Datang can eat enough, and Lord Jingwen is my Datang hero! The official of Sinong Temple said.

Although Jingwen was happy in his heart, he did not forget his own idea, that is, to collect patent fees.

"By the way, I don't have any opinion on the Ministry of Industry and Sinong Temple responsible for the production of Quyuan plows and seeders, but we should talk about patent fees!" Jingwen said.

"Royalties?" The officials of Sinong Temple obviously didn't understand what this thing was. (To be continued......)
