These cottons have already been processed and sent to Ding Haijun, and at the beginning, Zhao Xin planned to use these cotton to weave cloth.

The price of cloth in the Northern Song Dynasty is not high, and it is relatively stable, a piece of cloth is about 300 Wen, which has also become the main source of clothes for ordinary people.

Song ruler, a piece of cloth is about 2 feet wide and 40 feet long, even as an adult's clothes, a piece of cloth can make several pieces, compared to silk, too much saving.

Cotton cloth is appeared, but it is extremely rare, the Northern Song Dynasty is mainly grass cotton, suitable for weaving Indian cotton, only in the south, as well as the Western Regions, there are sporadic planting, by chance, after being weaved, the price is also extremely high, scarce is expensive.

Really pure white cotton, the price is even above silk.

The planting of cotton is for the future, a foundation for the development of light industry based on cotton textiles, and the current cotton, if weaving, is relatively costly, and the market prospect is not very large.

When enough shipwrights were found and the development of navigation began, Zhao Xin initially used silk as the material for soft sails, but the research on canvas continued.

Canvas actually appeared very early, under the premise of taking the earth as a unit, in fact, this technology line has already been lit, as early as the ancient Roman era, canvas has appeared, the earliest time was made of gloves, the kind used to raise eagles, and later, gradually developed to tents.

Canvas is a kind of cloth woven with thicker threads, because the lines are thick enough, relatively heavy, and similarly, more durable.

During this period of time in the Northern Song Dynasty, there was no cotton from India, but there was hemp, but no one thought about using them on this canvas.

Zhao Xin's crossing, many things that should not have appeared in the Northern Song Dynasty, appeared one by one, cotton is the same, and canvas is also the same.

Zhao Xin doesn't know a lot about machinery, even if it's the famous Jenny spinning machine, but the basic principle, I still know, to put it bluntly, is from a spindle, into several, the traditional method, into the integration method.

It's a pity that I don't know the basic structure, but I know the principle, and I can only let people study it slowly, but weaving is never something that only machines can do.

Spinning, even if it is an ordinary shuttle, with the cooperation of people, it is fine, not to mention, there are some traditional equipment, in Ding Haijun, Zhao Xin set up a huge factory for the manufacture of canvas.

In the absence of sufficiently efficient equipment, people have become the most important production unit.

At the end of last year, Zhao Xin decided to give a large amount of annual leave regardless of the huge pressure on production, basically, according to the distance of the journey, and gave subsidies, and to a certain extent, with the help of the merchant ships of the Ding Navy.

For Chinese, the Spring Festival itself is a traditional festival, the most important festival for the entire nation, and ancestor worship during the Spring Festival is the most important thing.

And, for these people, before coming to the Ding Navy, they were eliminated, or disasters, or on the verge of bankruptcy, in the countryside, that is the object of everyone's disgust, after all, people are poor and short-lived, in daily life, there are always some hurdles that cannot be passed, some people, can borrow money to tide over the difficulties, but these have no permanent property, or even in debt, how to borrow money.

In order to change their fate, or rather, in order to survive, they chose to leave their hometown and came to such a strange place as Ding Haijun, with the original purpose of surviving.

After all, they can't survive in their hometown, but no one thought that this time it would become the biggest turning point, Ding Haijun gave them a chance, not only let them survive, but also live very well.

According to the current average monthly salary of the Ding Navy, the number of 80 guan is placed in the Ding navy, which is not very eye-catching, this is just the average salary of ordinary skilled workers, and if you know a little bit of technology, you will go to 200 and go to 300, similar to Niu Dali, and it is an annual salary of more than 20,000 yuan, which is the crown of the entire Ding Navy.

But in other parts of the Northern Song Dynasty, what was the largest population in the Northern Song Dynasty, of course, it was the peasants, and the income of the peasants per mu of land was very limited.

In the case of silt fields in the south of the Yangtze River, the yield of an ordinary acre of land, under the premise of intensive cultivation and God's care, can produce 4 stones of rice, if the price is 700 Wen, the income of an acre of land is 2.8 guan, which sounds very high.

This algorithm can't be miscalculated, but for ordinary farmers, they can't get so much money, one acre of land and four stones, is the best paddy field, and the wind and rain must be smooth, and God will take care of it to be able to achieve the harvest.

Silt field, to put it bluntly, is on the river, which originally belonged to the location of the river, but now because of diversion, or other problems, there is no water under the premise of a kind of agricultural reclamation, because of the silt at the bottom of the river, it is relatively fertile, and can easily reach more than 4 stone yield.

This kind of field, the most afraid is the flood, once the amount of water is huge, if it rushes to the silt field, the loss will be heavy, not only the harvest of the season is gone, and even for a long time in the future, there is no way to reopen up.

Even if it is a top-level silt field, even if it is intensively cultivated, it reaches 4 stones, or even higher, but it is impossible for a farmer to sell it for 700 wen a stone.

700 Wen is the market price in Bianliang, the entire Northern Song Dynasty, not to mention the northwest, that is a special case of inconvenient transportation, in fact, the price of rice in the northwest is more expensive, the main expensive, is the freight, with the current transportation cost of the Northern Song Dynasty, the price of a stone is 7, the vast majority of it is the cost of transportation, and even his price is not as high as the price of Bianliang.

Of all the cities with convenient transportation, Bianliang has the highest price, and this is still the retail price.

Trafficking in grain, need freight, need profits, even in the local rice shop, the receipt price and the sales price, there is a big difference, in the harvest days, in the season when the grain comes down, the price of rice in Jiangnan is quite low, maybe the purchase price is not even 200 Wen.

In fact, this is also the profit of the large-scale shipping of the navy, through the shipping, large-scale cost reduction, when 30,000 materials, or even 50,000 materials of large fortune ships appear, the transportation cost of a single stone of grain, will be reduced to a very low level, not only will make the entire Northern Song Dynasty, the supply of grain more sufficient, but also disguised to lower some prices.

In this way, even if it is 4 stone of grain, after the farmer harvests, the price of all the sales will not exceed 800 Wen, 800 Wen to 1 Guan, which is actually the price of most of the land in the Northern Song Dynasty.

According to the price of 60 to 80 guan per acre of good paddy field, the interest on the land is actually extremely low, and if it is used as an investment, it may take a hundred years to be recovered.

Of course, it is impossible for a peasant to cultivate only one acre of land, but without the help of animal power and other forces, more than ten acres is already the limit, and even if a peasant has more than ten acres of paddy fields, it will only be a dozen or so in a year, and even the average monthly salary of Ding Haijun cannot be reached.

According to the ordinary average of 80 guan, a year, it is 960 guan, according to the average number of about 500 wen per mu of land, 960 guan, it takes 2000 mu of land to be able to produce.

Of course, the Haoqiang at the bottom of the Northern Song Dynasty could not rely solely on land, usury, and lower the price of grain in good years, sell it when the green and yellow crops were scarce, and when the disaster came, exchange some grain for land, which was the direction of development of the general mature landlords, and generally speaking, the land in their hands would be better managed.

But at the very least, it is equivalent to a small landlord of five or six hundred acres, and the most important thing is that this 80 guan is only one person's income, Ding Haijun has many job opportunities, as long as he is willing to do it, he will definitely be able to find a suitable job, and women can also come out to work.

Most of them are from a family, even if there are only three or four people working, with Ding Haijun's high welfare situation, throwing away expenses, each person can earn at least more than 300 yuan.

In the Ding Navy, 300 guan is really inconspicuous, Ding Haijun's high wages have given rise to higher prices, which are more than Bianliang, but in the countryside of the Northern Song Dynasty, the landlord who has thousands of acres of fertile land at home is not necessarily, and he can take out 300 guan at one time, which is really rich.

Millions of people have returned to their hometowns, taking away tens of millions of yuan in total, or even hundreds of millions, which is tantamount to a kind of outflow, but the effect is amazing.

More than 1 million people who go home to show off represent a million propagandists who don't give money, people trust seeing is believing, what these people were like before, what they are now, even if it is for wealth, there are many people who will fight.

These people came back, directly brought back more than 400,000 people, the indirect impact is even more, from the end of the New Year, even in the year, some outside personnel, there is an endless stream, in just one month, Ding Haijun directly increased by 400,000 people, in the next three months, there will be a large number of increases.

After all, considering the environment of Ding Haijun, some highly polluting industries are not suitable for the premise, and there are not many labor-intensive industries, and these people are not easy to resettle.

If you simply consider the economy, of course, where do these people come from and where do they go, but for the Ding Navy, how to absorb enough people in a limited time is the key, a small land of the Ding Navy, tens of millions of people, this is what must be considered, what is there to raise these people.

Jobs, for the Northern Song Dynasty, are very difficult, they can't be conjured out of thin air, but for Zhao Xin, it's very simple, for example, some management, duplicate positions, these positions, may not be efficient, but can improve the efficiency and taste of the whole city.

Now, there is a canvas project, of course, to accommodate a huge number of personnel, as long as it is to the ocean, the canvas must be increased development, the same canvas in the entire Ding Navy, the use is also very extensive, for example, tents, the original tent, mostly with linen and animal skins and the like, now with canvas, not only more strong, but also easier to build, this is also a military supply.

At the same time, the appearance of some auxiliary equipment on the battlefield, canvas, can also solve a lot of problems, which is a project that can be developed on a large scale.

Without enough machinery and equipment, you can only use people, traditional spinning machines, and looms, a series of modifications, increase the part of human control, you can barely produce canvas, but the efficiency is not high.

At present, the entire factory, with almost 5,000 people, produces less than 500 pieces of canvas per day, which is far from meeting the requirements.

Zhao Xin attaches great importance to canvas, so is the canvas factory, not only in terms of technology and resources, he is inclined to a lot, the number of times he comes, the canvas factory has also started from scratch, from the beginning, 50 people a horse, to the current 10 people a horse, increased by 5 times, and, under the care of Zhao Xin, put forward a new method, the loom and spinning machine, a certain transformation, is expected to improve the efficiency of one or two times, when the time, it is not the problem of insufficient productivity, but the problem of insufficient raw materials.

After Ding Haijun started this canvas project, all the harvested cotton was used for the production of canvas, because the needs of navigation, not to mention the future development, there is also a lot of demand now.

The launch of 20 experimental ships, which have been carried out over a long period of time, have proven the benefits of a number of sub-projects, such as spinnakers, such as soft sails, which are easier to control than fixed hard sails, and can even be navigated from different angles against the wind.

Perhaps, in some fields, some authority is not easy to break, but Ding Haijun, with Zhao Xin such a big Buddha pressing, whether it is status or knowledge, all surpass them, of course, they do not have that kind of qualification foundation, which also promotes the rapid use of this soft sail.

The new project has been reduced from the original 20 ships to 4, but all of them are large ships with more than 8,000 materials, and the sails are also quite mature, which may not reach the level of Spanish sailing ships, but the overall number is also quite large.

It turns out that if you use silk, these people will hesitate, the effect of silk is good, but the price is too expensive, a replacement, is dozens of times, or even hundreds, a sail, that is, with a month or two of time, so who can stand it, now, with canvas, maybe the price, will not be much less than silk, but the quantity and durability are higher, according to the theory in the experiment, the service life of canvas, at least 10 times more than silk.

In this way, the canvas produced by the canvas factory is sent to the shipyard almost immediately, and they will be turned into sails under the guidance of the shipwright, which will be the main use of the entire canvas in the future.
