Datang: Li Shimin begged me to rebel

"Have you tested it? How much can you plant in a day?"

"After leveling the cultivated land, with one horsepower, you can plant about seven acres a day." Liu Chang gave an approximate figure.

Li Ke nodded in satisfaction. This speed is already very fast, at least double the number of columbine carts before. When Li Ke was young, they interplanted wheat, and a mule can sow about ten acres a day. , that is, six or seven acres.

However, the area of ​​modern mu is larger than that of Datang, and it is already very good that Datang can achieve this efficiency, at least much more efficient than the current columbine carts.The most important thing is that these two iron wheels can save animal power and manpower, especially for those who are behind to control the columbine cart, so they don't have to work so hard.

Even when the animal power is insufficient, the columbine cart can be pulled by manpower to sow seeds.

There are not many other economic crops in Datang, mainly grain, and almost all of the grain is a single species. The efficiency of this kind of columbine is naturally extremely high.

It can be said that these advanced tools are all releasing productivity, but the premise is that the amount of iron smelting in Datang must keep up.

These semi-iron planters consume more pig iron than Quyuanli. If they want to spread to the whole Tang Dynasty, they have to dig iron ore in various roads of Datang and start iron smelting.

"The promotion will start this year, and the large-scale construction will start now. The promotion will start from the Guannei Road first." Li Ke thought for a while, and made a decision directly. Second, the people have no money in their hands.

So Li Ke has already started to think of ways to reduce costs, and he thought of another trick. When Li Ke was a child, the common people didn't have that much money, and it was impossible to buy chemical fertilizers every year. So, at that time, the government would provide agricultural loans to the common people. , I believe anyone who grew up in the countryside has heard of this thing.

Agricultural loans usually have a one-year term, that is, the loan is used to buy chemical fertilizers in the spring, the loan is repaid in the fall after the grain is sold, and the loan will continue in the next spring.

The interest rate of agricultural loans is very low. Li Ke remembers that many businessmen still had this idea at that time. When they ran out of funds, they went to the village to trick many villagers into helping them with loans and giving them part of the money.There are few people in Li Ke's hometown who do this, because there is a lot of land, and the people need a lot of agricultural loans.

And in some places with little land, people can't use so much agricultural loans, so some people do it like this.

Maybe Li Ke can use this method to give loans to the people of the world to buy columbine carts and Quyuanli?

It is not impossible.

In fact, if it is a loan, Li Ke's expenses will be even less, because from the outside world, Li Ke will take up a lot of funds, a plowshare costs three hundred cash, and there are so many people in the world, how many people can Li Ke support?

But in fact, the cost of Li Ke's own production of a quyuan plowshare is only a dozen yuan, and the funds occupied by these quyuan plows are far less than what outsiders think.

Calculated according to one hundred coins, the 3000 million people in the world are only one billion coins, and the 10 million coins in Li Ke's hands are more than 200 billion coins.

Besides, this thing doesn’t need one person from the common people, but only one household. At present, there are only more than 300 million households registered in the Tang Dynasty. If you think about it carefully, tsk tsk, drizzle.

So... can people be tricked here?Is there anyone who stands up and is willing to cheat himself?

What's more, when the cost of the Quyuan plowshare is loaned to the people, Li Ke can recover it in other ways. For example, when the people are in slack, can they deduct part of the loan money by working?

Nowadays, people in most areas mainly plant food, because the crops are almost the same, so when they are not busy, there is slack time for farming.

If these hours are used to work for Li Ke, a certain loan can be deducted, but in fact, perhaps the value they have made after working for a month or two has already earned the money for the plowshare, and the rest, Li Ke Isn't it pure profit!

And it will not delay the livelihood of the people!After all, productivity has been liberated!

There are tricks and tricks, but someone is needed to help Li Ke calculate the relevant basic data, or... leave it to Li Tai?

Li Ke's mind has already had countless coquettish operations, oops, it's another day with blood boiling in his mind.

Think about it, manipulating the people of the world is really exciting.

By the way, mules can also reproduce in large numbers. Although there are already mules in the Spring and Autumn period, I am afraid you will not think that mules still cherish ornamental animals at that time. They are mainly used for viewing by the royal family and nobles. The benefits of mules are not many. Having said that, although its fertility is extremely poor, its service life can reach 30 to [-] years, far exceeding the work value of horses and donkeys.

Moreover, the vitality and disease resistance are extremely strong, the strength and endurance are extremely high, and the food intake is average...you taste it carefully.The perfect tool mule!

The service value is much higher than that of horses and donkeys, so it is not very good to promote it.

At present, the ownership of Xizhou and Eastern Turks gave Datang a large number of pack horses. These pack horses are not suitable for war horses, but they are used to breed mules.

Mule generally refers to the product of a male donkey and a female horse, called a horse mule, or mule for short.

The product of a male horse and a female donkey is called a donkey mule. The donkey mule is also very good, but it is worse than the horse mule, so it is better to breed the horse mule.

Hey, not bad, I found another job for Li Tai.This is also a measure that requires a large number of statistics on the stock of folk donkeys and horses.

"Master Lu, how is your improvement?" Li Ke turned to Lu Daqiang again.

"Returning to Your Highness, we have been improving papermaking and printing techniques, and we are jointly advancing movable type printing and engraving printing. The books and contents suitable for printing are different for movable type and engraving. Both can be used. There is not much room for improvement in the version, it can only be improved in the material, but in fact the improvement is limited.”

"At present, the main improvement is to optimize the printing ink, and see if we can find a more suitable and cheaper ink. The main improvement is the paper."

"We used different materials to conduct experiments, almost similar to what your highness said, we have tested all the things with fibers, and added different types of glue to them, such as glutinous rice juice, gum Wait." Lu Daqiang introduced to Li Ke the improvement plan of printing and papermaking.

In terms of printing, in fact, Li Ke provided them with more advanced printing machine structure diagrams, but it cannot be said how advanced they are. These printing machines are also stored in underground warehouses, but they are manual large-scale printing machines. It is a bit like the kind of printing machine around the period of the Republic of China or World War II.

However, these machines are still quite difficult for this era, and it is impossible to complete them in one step, so it is better to let them improve slowly.

In fact, the improvement in paper is of greater significance. The current paper price is still a bit high. After the cost of paper continues to decrease, it will have a greater effect on promoting society.
