Raw materials for industrialized countries, is a key, there are not enough raw materials, the machine is a furnishing, the more developed the project, the requirements for raw materials are about important, both quantity and quality are an important basis.

The northwest was influenced by Han Qi, and promised to complete 1 million mu to 1.5 million mu of cotton planting this year, Zhao Xin is more satisfied, with these, according to the output of 30 catties per mu, you can get 30 million to 45 million catties of output, basically can supply the production of canvas, as well as the daily consumption of the navy.

The effect of cotton, as long as it is planted, can be shown, as long as it is planted in the northwest, it will be attracted, and the cotton planted in the northwest has natural advantages, as long as the income exceeds 1 or more, large-scale promotion is almost inevitable.

This is not the final yield, crops, its yield will change, Zhao Xin, as a child from a remote mountainous area, is very familiar with planting, cotton, the most common cash crop in later generations, of course, is also very familiar.

One acre of real estate 110 catties of cotton, this number can never be called much, the current level of science and technology, as well as the situation of cotton seeds, it is impossible to meet the standards of later generations, six or seven hundred catties of output, but Zhao Xin's requirements are not high, just an average number, about 300 catties.

Even if it is only half of the average yield per mu in later generations, 300 catties, it is twice as much as now, which is more beneficial for cotton.

In the first year of planting, it was only 150,000 mu, and there was no experience, Zhao Xin had already passed on a lot of experience to agricultural experts, but it also took time for agricultural experts to understand it thoroughly.

In a year's time, planting in the land is only one season, but for the experimental field, it is not one season, but two seasons and three seasons, and even regular planting, carried out many times, after at least two and three seasons of cultivation, these people are quite familiar with cotton.

Small field planting, the highest yield per mu, in the first season, reached 150 catties, the second season exceeded 280 catties, in the third season, it can even reach 450 catties.

This number is very amazing, even if it is reduced according to the large-scale planting, but how to calculate, it can reach about 240 catties.

In addition to the improvement in planting, there is also a slight increase in processing, and the conversion rate of seed cotton has increased slightly, basically reaching the level of 3 to 1.

In this way, 240 catties of mu yield can produce 80 catties of lint, which has been improved too much compared to before.

Even according to the current figures, 1 million mu in the northwest, 300,000 mu near Baozhou and Daimyofu, the attraction of cotton is very terrible, and interests are the best driving force.

Because of the relationship between propaganda and hesitation, this promotion is not high, but 1.3 million mu, with the support of new planting methods and seeds, 80 catties of lint, the total output will be as high as 104 million catties, compared with before, the increase is very obvious, and the fraction is almost last year's output.

1004,000,000 catties, sounds very high, the total output is only more than 50,000 tons, and the per capita share is only 1 catty, far from the average level, and the market is very vast.

However, with the increase in production, as well as the gradual popularization of cotton cloth, the price of cotton will almost inevitably decrease, but no matter how it is reduced, the output will skyrocket nearly three times, and the income will increase, even if the planting has increased so much, the output will also increase, but the price of cotton will not decrease a lot, probably reduced to about 40 Wen, even if it is this, the income of one acre of land will exceed 3 times.

For a person can cultivate about 10 acres, farmers can get 30 yuan of income for a season of cotton, which may be a year down, that is, a few times for the vast number of farmers, is a huge temptation, and even the first to intervene, is those landlords, farmers may also have to consider, this ration and cotton income comparison, for the landlords who have too much land, they will not consider this, they consider, the main thing they consider is the income.

Historically, the large-scale popularization of cotton is also the fact that these landlords, compared with ordinary farmers, they have insufficient resources and information, even if they know that planting cotton makes money, but they can't support the cotton input.

Now is the promotion period, Dingjun will be responsible for all the cotton seeds, once it enters the outbreak period, after ordinary people recognize the benefits of cotton, cotton seeds must be purchased.

After all, agricultural science and technology is basic science and technology, experimental fields, all kinds of experiments, these all need funds, a normal development, is to rely on the cultivated seeds, continue to obtain income, and then put the income into research.

As an agriculture, seeds are the foundation, he is even on top of the chemical fertilizer, the seed determines the innate foundation, and even for cotton, there is a question of yield and fiber quality, these subdivisions will make the seed a good direction.

By next year, the problem of cotton can be solved, and the textile industry, which has been accumulating technology, can also follow the opening, and the strength shown by the combination of cotton and industry can support the rapid development of a country.

Even if there may be more than 100 million catties of output next year, it will be next year, and now, in Zhao Xin's hands, there are only 4.5 million catties.

4.5 million catties of cotton, is not equal to 450 catties of cotton, from cotton to cotton thread, and then to cotton, although the consumption is very small, but there is still there, and the manufacture of canvas is even more so, the consumption is greater.

The loss of manufacturing canvas may not even be 4 million catties, a super sail like a Spanish sailing ship, 4 masts of the capital ship, hundreds of sails, heavy sails, a ship needs at least thousands of catties of canvas, or even tens of thousands of catties.

According to this calculation, these canvases may not even be able to build 400 ships, how many sailboats are needed to cross the seven seas, 10,000 are not much, this alone is very terrible for the consumption of cotton.

Navigation is to develop slowly, 10,000 is just a vision, and the largest ship currently under construction is only about 300 tons.

This ship, in fact, is a ship with a lot of expectations, 300 tons, converted, is the appearance of eight or nine thousand materials, for the Northern Song Dynasty, which can make the Nanhai No. 1 800-ton ship, it is not a very high-end one.

But it is different, his tonnage comes from the overall use, not the tonnage brought by the boxy hull of the Chinese sailing ship.

It is exactly the appearance of an ocean-going vessel, reducing the bow and stern, especially the height of the bow tower, and replacing the original round stern with a square stern instead of a Galen ship, these characteristics of the Galen ship are perfectly applied to this ship.

Compared with the Fukun, this new design is relatively long and narrow, has a faster speed, and has excellent maneuverability in headwinds.

Such a ship can only play a role when it enters the ocean, which only Zhao Xin knows, others don't know, and even some ship designers also propose whether to make a lucky ship, if there is a steel keel provided by the steel mill, they can make a ship of 15,000 or even 20,000 materials.

For shipbuilding, the most difficult thing is actually the keel, as long as the keel is solved, the rest is just a matter of splicing, putting together various wooden planks, so that the ship is finally formed.

With their first manufacturing experience, they felt they could give it a try.

This opinion, of course, was suppressed by Zhao Xin, what kind of jokes, what is good about the lucky boat, even if it is to get a 1,000-ton or even 2,000-ton lucky boat, he is also playing in the offshore sea.

In the whole of Asia, there is no problem, from the Northern Song Dynasty, to Southeast Asia to India and Arabia, all the way are commercial ports, which is the foundation of Zheng He's fleet, but after arriving in Africa, it is okay in East Africa, once it goes down, it is all primitive tribes, and without enough supplies, it can only return.

This is the obvious difference between the East and the West, the East is the only one in China, but in the West, on the entire European continent, there are many powerful countries, in Spain and Portugal, control the shipping lanes in Africa, through one or two hundred years, established a supply line, the later Britain and the Netherlands, can not pass through this supply line, to the Golden Country, then there is only to the rough Atlantic Ocean to find opportunities.

From this moment on, Europe embarked on a completely different path from the East, which is also the rapid rise of Europe from the Renaissance, and correspondingly, in Eastern China, it gradually declined.

Maybe the lucky boat is not the culprit of this, but Zhao Xin doesn't dare to bet, as long as the keel is determined to be the keel of the sea ship, the rest, even if there are some changes, will not affect the overall situation.

A seed is slowly taking shape in the navy, a completely different from the traditional Chinese sailing ships, more suitable for ocean voyages, in the near future, dozens of ocean-going ships composed of a fleet, successfully across the Pacific Ocean, arrived in the Americas.

In fact, it is not so difficult to travel from Asia to the Americas, not to mention the road from Japan to the north, which is dotted with islands, which can support non-stop exploration, and as long as you build supply points, you can continue to expand the shipping routes.

Even if it crosses the Pacific Ocean, it is much easier than the Atlantic, the largest ocean in the world, not only is the area extremely large, but it is also relatively stable.

At the time of World War II, almost all the participating countries had aircraft carriers, but the place where the real aircraft carrier war was fought was only the Pacific Ocean, and there was only a stable Pacific Ocean, which could support the aircraft carrier as the main force of the operation, placed in the Atlantic, the waves were turbulent, and it would change to the Atlantic Ocean at any time, and there was very little time for the aircraft carrier to release the aircraft to fight.

In the canvas factory, almost from scratch, from simple handwork, to machinery manufacturing, the output is getting bigger and bigger, 4.5 million catties of cotton, almost can support five or six months, there is five or six months, almost, can also support the next season of cotton harvest, which is also the reason why Zhao Xin does not continue to expand the scale of production.

Six months will become the most important six months for the navy, and the foundation of the ocean will be completely laid at this time, and a large number of ships within 10,000 materials will be built, and another plan can be started.

Sailboats built with soft sails are very suitable for ocean sailing, but the requirements for sailors are relatively high, with many rigging, different sail maneuvering methods, and many different sea conditions and shipping lanes, which require experience, and a lot of experience.

Before the opening of the ocean, there is one most important thing that must be carried out in advance.

The reason why the sea is vast and unpredictable, the complex weather and strong winds are one aspect, and another aspect is positioning.

Different from the land, different landforms, marked mountains and rivers, can determine the direction, people who walk a few times, know how to go, but above the sea, there is sea water everywhere, all are exactly the same, there are no signs.

Don't talk about islands, on the sea, islands are always the few, and on the vast sea, even if it is a telescope, you can see more than ten kilometers away.

Getting lost is a very terrible thing, in the middle of the sea, if you lose the channel and get lost, the result is probably to be buried under the water forever.

Zhao Xin is a historian and does not know astronomy and geography, but he also knows that an important invention in the history of navigation, the sextant.

A sextant, to put it bluntly, is an optical instrument used to measure the angle between two distant targets. The sextant can be used to measure the angle between the sun or other celestial bodies and the sea horizon or horizon at a certain time, so that the latitude and longitude of the position of the ship or aircraft can be quickly known.

Before the absence of satellite positioning GPRS, the sextant was the most convenient and simplest way to measure the distance.

Zhao Xin didn't know the specific composition of the sextant, but he knew that the sun and a certain celestial body were used to shine at different positions to form a certain angle, and then divide the latitude and longitude, and then determine the position.

On the premise that there is no way to make a sextant, there are only a large number of measurements, for example, the angle of the sun at different times and the same place, and when this data is enough, a good chart can be formed.

On the sea, it is not easy to determine the location of such a measurement, but on the land, it is very easy to go, with different places, a large number of tests, to form a large series of data, and then form a nautical chart and longitude and latitude, when the continental net is fine and accurate enough, the sea, is a filling process.

From the very beginning, Zhao Xin determined that the ocean-going fleet of the Dinghai Navy was a pioneering and constantly exploring fleet, rather than a fleet that was guarded and marched along the original waterways and trade routes.
