Zhao Xin never doubted whether Southeast Asia was taken or not, this has never been a problem, since the start of the war, in all aspects, the Dinghai Navy has occupied a crushing advantage.

The national strength of the Dinghai Navy is huge, with a population of nearly 100 million, and the war potential is huge, not to mention the superiority in weapons, but also the population, which can overwhelm the countries of Southeast Asia.

In the same way, in terms of weapons, in terms of survey, in terms of logistics, yes, in terms of logistics, in operations spanning thousands of miles, in terms of logistics, the navy can even be stronger than the indigenous people of Southeast Asia who are fighting on their own soil.

This is science and technology, race, and the comprehensive crushing of weapons, the only thing Southeast Asia can rely on is the large-scale epidemic of malaria, once malaria is infected on a large scale, causing a large-scale spread, and a large number of deaths and injuries under the premise, even if it is to kill a little less people, Zhao Xin will not continue.

Zhao Xin is a traverser, many problems, as early as before arrival, have been considered in advance, malaria, a very terrible, highly contagious disease, is also in the scope of consideration, and do a good job of prevention.

Not every place in Southeast Asia has malaria, otherwise, where there are people in Southeast Asia, long ago died, this is different from other infectious diseases, there is a long incubation period, antibodies and other problems, even in the 21st century, is a problem that plagues the world health, Southeast Asia and Africa, these countries in the tropics, perennial affected by this.

Not to mention the prevention and treatment of traditional Chinese medicine, even in the 21st century, having quinine, a special drug to deal with malaria, may not be able to stop the large-scale spread.

Fortunately, in this era, malaria has not yet developed to the next generation, such a terrible degree, even if there is no quinine, some active ingredients of traditional Chinese medicine, as well as trees of the same species as the cinchona tree, are not non-existent, do a good job in many aspects, traditional Chinese medicine and prevention go hand in hand, plus a certain amount of luck, until the Dinghai successfully went to the island, and on the island, laid a huge advantage, won a huge territory, malaria has not spread on a large scale, which is a very good thing for the Dinghai Navy.

As long as there is no large-scale outbreak during the war phase, then there will be some occupation.

To deal with malaria, the most important thing is to do a good job of sanitation around, eliminate some stagnant water or very polluted waters, do a good job of preventing mosquitoes and flies, and culling some mosquitoes, insects, rats and ants on a large scale, so that the source of infection and the route of infection can be suppressed, and large-scale transmission can be effectively avoided.

Good news one after another, especially some non-ferrous metal deposits, many mineral deposits, can even be said to fill the domestic gap, for example, copper ore, for example, manganese ore, nickel chromium and the like, although some minerals in China are also very rich, but the navy is not good.

As far as copper ore is concerned, whether it is Jiangxi or Yunnan-Guizhou in China, it belongs to the territory of the Northern Song Dynasty, and it can be obtained from the hands of the Northern Song Dynasty by purchasing it, and there are very few of them.

There is a shortage of copper in northern China, the only valuable copper mine with huge reserves, now in Mongolia, the 11th century is different from the 21st century, the world borders have not yet been divided, after defeating the Liao State, and defeating the Jurchen and Mongolia, Mongolia is actually within the control of the Dinghai Navy.

The copper mine, because it is the third largest gold and copper mine in the world, Zhao Xin has also seen its records on the Internet and the news, it should be discovered at the end of the century, or at the beginning of the 21st century, when it was discovered, it caused a huge sensation, because this gold and copper mine containing 1,200 tons of gold and more than 37 million tons of copper is located less than 200 kilometers away from the Chinese border.

If the border is divided a little further north, this huge gold and copper mine containing huge wealth is not China, this kind of thinking is the statement of many netizens, as well as many angry young people on the Internet.

In this era, there is no so-called national border, let alone Mongolia, such a gold and copper mine, Zhao Xin even knows the general direction, but it is still difficult to mine.

The reason is very simple, it is in a desert, or underground, there is no 21st century mining conditions, there is no 21st century technology level, it is able to look at the ocean.

Southeast Asia, especially Indonesia, has copper resources, here, even if a small copper mine is found, it is a very big support for the Dinghai Navy, so once discovered, it was immediately explored and measured, and the preliminary work was started.

There is a lot of good news, mostly minerals, but also some flora and fauna, as well as vegetation endemic to Southeast Asia, such as spices.

Once, for the Spaniards and Dutch in Asia, the most important goods should be spices, in the archipelago of Southeast Asia, there are even islands specializing in the production of spices, for Europeans at that time, spices and silk and porcelain are the same as gold, France is still the royal family of Austria-Hungary, in the royal banquet, in order to show luxury, even a plate of spices.

This was a joke, like Napoleon's aluminium vessels, but at the time, it was incomparably extravagant, even more luxurious than carved gold.

Spice Island, Zhao Xin wrote out, if you have the ability to find it, the navy will definitely look for it, but it is not the most important thing, national strength or something, not spices that can be solved, and China is not short of spices, but in the Northern Song Dynasty, it has not been discovered and valued.

Southeast Asian spices, if they are found, can be picked smoothly, there is no problem in picking them, and if they can't be found, they will not spend a lot of effort to find them, there is no need for this.

The situation in Southeast Asia has gradually calmed down, and the key areas have been occupied, and all that remains is to use time to consolidate the occupation and open up some areas for comprehensive development, so as to achieve the problem of supplementing the navy, and this is not a problem that can be solved in a short time.

Not to mention anything else, Japan and North Korea have been occupied for so long, and the domestic personnel have been transferred almost under the premise that the plan has not been thoroughly completed, this is only a stone's throw away from the Dinghai Navy, relatively speaking, Southeast Asia is a little too far apart, even if there is Hainan Island as a springboard, it is not easy.

Zhao Xin had just finished processing an official document and was about to prepare for the next moment, when a news arrived, according to the direct telegraph report from the port and the palace, corn had been discovered, and at least 5 tons of corn were being clipped, coming quickly towards the Dinghai Navy.

Corn, 5 tons of seeds, or corn from one of the three major crops, Zhao Xin almost jumped up after hearing the news, after 2 years of difficult exploration, finally successfully crossed the North Pacific, found the Americas, and made a great discovery in geography, it can be said unceremoniously that the discovery of the three major crops is just a time relationship, maybe a year, maybe two years, maybe three years, there is almost no problem of not being discovered.

However, how long it will take to find out is still a key question, and when the good news came one after another in Southeast Asia, once upon a time, I was also wondering if the three major crops would be discovered now, even if there was none, rubber or something could be found.

Of course, this is all utopian, if among the three major crops, the first to be discovered, I'm afraid only corn, he should be able to grow in North America, the rest, mostly in Central America and South America, now, even if the road to North America is opened, to Central America, or even South America, it is very difficult.

The prospect is good, but the road may not necessarily be smooth, and it is impossible to say how long it will take to find out, he just hopes that he can find it sooner.

Now, not only did it find, of course, it was still corn, but it was still unexpected to send five tons of seeds over at one time.

In this world, those who know the use of corn, and even know what corn contains, that is, Zhao Xin, can be said unceremoniously that among the three major crops, Zhao Xin attaches the most importance to it, and it is also the most optimistic, that is, corn.

Coming from the Americas, transportation and communication are not convenient, the clipper ship is already the fastest in the world, but such an important news, as long as there is a ship relay, even if it is 3 days in advance, 5 days in advance, it is also an advance, and the news is reported in advance, so that there is time to prepare here.

Such a huge amount of crop seeds had to be brought back without preparation in advance, and as soon as the ship that reported the news arrived ashore, it was sent to the Dinghai Imperial Palace by telegram.

In fact, it turned out that this method was right, and when he got the news, the seed was at least 5 days away from the Dinghai Navy, and in 5 days, it was enough for Zhao Xin to make corresponding arrangements.

For planting, an extra 5 days is an extra season of planting, which is very important at some key nodes.

When the clippers carrying the seeds arrived at the port of Huludao in the Dinghai Navy, they were greeted with unprecedented enthusiasm, almost with a military band, a welcoming crowd, and a large number of troops.

Zhao Xin's attention to corn is on top of all the things found before, even if he knows that the entire Dinghai Navy is safe, even if he knows that there will be no problems in transporting these things to the plantation, he wants to express this kind of attention.

At least two regiments of troops escorted a wagon of seeds that could not be wagoned, and even loaded the seeds separately, with 300 kilogram boxes in each wagon, and then, guarded by at least one company of soldiers, the security guard reached the extreme, until it entered the botanical garden.

Plantation, this is a unique thing in the Dinghai Navy, before, in the Dinghai Navy's botanical research institute, that is, about 1,000 acres, not that Zhao Xin did not pay attention to it, but the land of the entire Dinghai Navy was limited, and even to a certain extent, it expanded outward, and purchased 5,000 acres of land on the mainland of the Northern Song Dynasty to carry out local cultivation and research, at that time, it was to support the large-scale popularization of cotton in the Northern Song Dynasty, and interplanted cotton with wheat.

Dinghai has always attached importance to the tradition of plantations, after occupying the Liao State, this problem was solved, on the Liaodong Peninsula, on the vast land of the Liao State, the construction of a plantation covering an area of 100,000 acres.

5 tons of seeds, almost 10,000 catties, according to the calculation of 3 catties of single grain sowing of one acre of land, double grains are 7 catties, 10,000 catties, that is, 1,500 acres can be planted.

Of course, the planting of the experimental field cannot be the same density as the ordinary planting, and the data given by Zhao Xin shows that they are almost twice as sparse, which is a single grain, that is, a total of 6,000 acres are planted. This part of the field is considered to be a very small minority among the experimental fields of the plantation, but it almost concentrates most of the researchers and farmers of the plantation.

About the method of planting corn, has already been distributed, to participate in this planting, have passed several rounds of learning and selection, to all aspects of the precautions, are to memorize the rolling melon ripe, now, finally to the actual operation, are skilled workers, or research scholars, in this aspect, very specialized, of course, is very good.

This planting method is quite sparse, and because of strict management, this is a plantation, at least more than 4 laborers per acre, and a large number of scientists, researchers, scholars conduct research, plant in accordance with scientific methods, and carry out a series of adjustments, in the end, the growth period is only a little more than 4 months, a little earlier than wheat, not as good as the growth period of double cropping rice, but

However, the yield is extremely amazing, and the seed-to-income ratio is almost 300 times.

Although this is the first harvest crop, this yield is too amazing, take the wheat planted by the Navy as an example,

The seeds needed are about 20 catties, but the final yield is 4 stones, that is, 20 times, and in most cases it is almost less.

Rice is a little better, about 10 catties of seeds, but the seedlings must be cultivated first, and the cultivation can be transferred to the paddy field for planting, and the yield is about 6 stones, that is, 60 times.

But corn, but can reach 300 times, this multiplier, very terrible, in the three major crops, are like this, the rate is extremely high, this rate, is also the basis of the yield, even if it is some other research, such as hybrid rice, is to increase the weight of the ear of rice, to increase the yield, the rate of hybrid rice is also very high.

Of course, this is the production of the laboratory, to ensure the efficiency of a single plant, rather than high-density planting, after some deletion, taking into account the ordinary environment, according to an acre of land planting about 7 catties, the yield is reduced with 120 times to 150 times, this total is calculated to be the total yield of corn, at least more than 8 stones, and even 10 stones, this terrible number, compared to more than 4 months of growth, can even be interplanted with wheat, which is a common thing in northern China, Guarantee two seasons of food a year, so that the output of the land can reach the limit.
