"Has it been tested? How many can be planted in one day?"
"After leveling the cultivated land, if one horse is used, it can probably sow about seven acres a day." Liu Chang gave a rough figure.
Li Ke nodded with satisfaction. This speed was already very fast. At least the number was more than doubled compared to the previous columbine. When Li Ke was a child, they interplanted wheat. One mule a day could sow about ten acres. If wheat was grown alone, , that is, six or seven acres.
However, modern acres are larger than Datang's. Datang's ability to achieve this efficiency is already very good, at least much higher than the current columbine efficiency. The most important thing is that these two iron wheels can save animal power and manpower, especially the person behind the wheel does not have to work so hard.
Even when animal power is not enough, columbines can be pulled by humans to sow seeds.
There are not many other cash crops in the Tang Dynasty, mainly grain, and almost all grain is grown in a single type. The efficiency provided by this kind of column is naturally very high.
It can be said that these advanced tools are releasing productivity, but the prerequisite is that Datang's iron smelting volume must keep up.
These semi-iron planters consume more pig iron than the Quyuan plow. If they want to spread throughout the Tang Dynasty, they can only dig iron ore in various roads of the Tang Dynasty and start iron smelting.
"Start the promotion this year, and start large-scale construction now. Start promoting it from Guannai Road." Li Ke thought for a while and made a decision directly. The promotion speed of this kind of iron columbine cannot be fast. Once pig iron is introduced, Production restrictions, and secondly, people have no money.
So Li Ke had already begun to think of ways to reduce costs, and he thought of another trick. When Li Ke was a child, people didn't have that much money, and it was impossible to buy fertilizer every year. Therefore, at that time, the government would provide agricultural loans to the people. , I believe anyone who grew up in rural areas has heard of this stuff.
Agricultural loans usually have a one-year term, that is, you borrow money to buy fertilizer in the spring, sell the grain in the fall to repay the loan, and continue next spring.
The interest rates on agricultural loans were very low. Li Ke remembered that many businessmen 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 the villagers 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.
In some places where there is little land and people cannot afford so many agricultural loans, some people do this.
Maybe Li Ke can use this method to provide loans to people all over the world to buy columbians and plows?
It’s 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 coins. There are so many people in the world, how many people can Li Ke support?
But in fact, the cost for Li Ke to make a Quyu plow was only a dozen yuan, and the funds occupied by these Quyu plows were much less than what outsiders thought.
According to the calculation of one hundred liters, the 30 million people in the world are only 1 billion liters. The 12 million liters of money in Li Ke's hand is more than 10 billion liters.
Besides, this thing does not require the common people to have one, only one per household. At present, there are only more than 3 million registered households in the Tang Dynasty. If you think about it carefully, tsk tsk, it’s drizzle.
So...could there be any deception here? Is there anyone who is willing to step forward and give himself a hard time?
Also, when lending money to the people, Li Ke can recover the cost of the Quyuan plowshare in other ways. For example, the people can deduct part of the loan money by working during the slack period?
Nowadays, people in most areas grow mainly grains. Because the crops are almost the same, there is leisure time when they are not busy.
If they worked for Li Ke during these times, a certain amount of the loan could be deducted, but in fact, maybe the value of what they had done for one or two months would have already earned the money for the plow, and the rest, Li Ke Isn’t it just pure profit?
And it won’t delay people’s livelihood! After all, productivity has been liberated!
There are efforts and there are efforts, but someone is needed to help Li Ke calculate the relevant basic data, otherwise... leave it to Li Tai?
Li Ke's mind was filled with countless sexy moves. Oops, it was another exciting day in his mind.
Think about it, controlling the people of the world is really exciting.
By the way, mules can also reproduce in large numbers. Although mules have been around since the Spring and Autumn Period, you may not have thought that mules were still prized as ornamental animals at that time. They were mainly used for viewing by the royal family and nobles, and the benefits of mules were not many. Having said that, although its fertility is extremely poor, its service life can reach 20 to 30 years, far exceeding the working value of horses and donkeys.
Moreover, the vitality and disease resistance are extremely strong, the strength and endurance are great, and the food intake is average... taste carefully. The perfect tool mule!
The service value is much higher than that of horses and donkeys, so it is not easy to promote it.
The current ownership of the Western Continent and the Eastern Turks has allowed the Tang Dynasty to have a large number of pack horses. These pack horses are not suitable for use as war horses, but they are perfect for breeding mules.
Mules generally refer to the product of a male donkey and a female horse, called a horse mule, or simply a mule.
The product of a male horse and a female donkey is called a donkey and mule. Donkeys and mules are also excellent, but inferior to horses and mules, so it is better to breed horses and mules.
Hey, not bad, I found another job for Li Tai. This is also a measure that requires a large number of private donkey and horse stocks.
"Master Lu, how are your improvements?" Li Ke turned to Lu Daqiang again.
"Returning to Your Highness, we have been improving papermaking and printing. We are jointly advancing movable type printing and engraving printing. Both movable type and engraving are suitable for printing books with different contents and can be used. However, at present, both There is not much room for improvement in the pattern, and we can only improve the material, but in fact the improvement is limited.”
"The main improvement at present is to optimize the ink in printing to see if we can find a more suitable and cheaper ink. The main improvement is paper."
"We have used different materials for experiments. It is almost similar to what your highness said. We have tested all the fibrous things, and also added different types of glue-like substances to them, such as glutinous rice juice and gum. Wait." Lu Daqiang introduced to Li Ke the improvement plan for printing and papermaking.
In terms of printing, Li Ke actually provided them with structural diagrams of more advanced printing machines. In fact, 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's a bit like the printing machine used during the Republic of China or World War II.
However, these machines are still quite difficult for this era. It is impossible to get them right in one step. It is better to let them improve slowly.
In fact, improvements in paper are of greater significance. The current price of paper is still a bit high. When the cost of paper continues to decrease, it will have a greater effect on promoting society.
