Food security is always the most important issue, and it may be vaguely felt in the feudal dynasty, especially in the Navy.

These people of the Food Research Institute are almost always talented, they can join the Food Research Institute, they are already stronger than many people, as for the origin, is a variety of, there are many, from the most desperate environment out of the most desperate.

The time of the establishment of the Navy, full of calculation, not more than 10 years, many people have not forgotten why they arrived in the Navy.

The first personnel of the Navy were the poor coastal fishermen recruited by the Navy, the victims of the two Huaihuai, and the relatives of some of the soldiers, in the middle of which the army need not say, although at the bottom of the society, they can fill their stomachs.

Disaster victims and poor fishermen are not the same, most of them, are unable to live, in order to survive, choose to set the navy, choose to live in the Navy, if you go to the Navy or choose to plant the field, you will know the Navy grain per mu of terrible.

In the daily, the output of 2-3 stones has made some experienced old farmers, very gratified, this is God's care, the yield of the year, 4 stones, almost only in the upper water field, and take care of well, after cultivation can.

But in the fixed navy, 4 stones is just an ordinary, 5-6 stone often appear, this is already a limit, compared to the average person, planting food, more than double the income, such income, quite terrible, but now, the number of 8 stones is placed here, directly breaking through the income of the intensive cultivation of the upper paddy fields, which is very terrible.If Zhao Xin told them that this is not the limit, the limit of corn should be about 1500 pounds, which is nearly double the number of 8 stones now, and they will not believe it.

The example before us proves that this is a reality, an indisputable reality, and now that those who know this reality have expanded.

When the land has increased to 2 million mu, in the future, even according to the output of 8 stones, the total output will exceed 16 million stones, if it is to feed people, these foods are enough to feed more than 5 million, which is a very large output.

The most important thing is that 2 million mu may be in the area of the entire fixed navy land, not very large, but when the output reaches 16 million stones, if calculated according to the planting of 7 pounds per acre, the planting area is more than 300 million mu, this figure is terrible.

How much land there is in the Northern Song, 800 million acres of looks, the current land occupied by the Navy is much larger than that of the Northern Song, but it is somewhat inferior to the area of cultivated land.

The original Liaoguang territory, either in the grassland or desert, or some high latitude areas, if there is no tradition of planting, arable land development is somewhat difficult.

Of course, these difficulties, for the fixed navy is nothing, after taking the entire Liaoning land, a certain amount of planning was carried out, in addition to the inventory of the original land planted with grain, but also carried out a certain plan, to cultivate more land.

In order to determine the Navy's ability and vision, but also really planned a lot, the three northeastern provinces add up, should be in the 3-35 million, Inner Mongolia added up to 150 million, plus the original in China outside the northeast land, North Korea, Japan, and some islands, the view, the Navy can cultivate the land area, at least also in the 1 billion to 1.2 billion,

However, the difficulty of development is somewhat large, Zhao Xin is also impossible to large-scale deforestation and open fields, most of them are some orderly development, after a few years, the northeast and Inner Mongolia development of the most mature, arable land area totaled about 270 million mu, Japan and North Korea, or the original planting area, there is no large-scale expansion.

If all these lands are used to grow corn, it is necessary, but the food produced is also poured, and there are many processing methods, and those corn poles will not work.

An acre of land produces more than 3 tons of straw, which is a very large number, although it is said that after the storage of corn straw, it is very good for animal husbandry, but for ordinary farmers, there is no need for this.

Responsible farmers experts, did not pass on the green storage, for a single farmer, or small farms, they did not have so much energy, many aspects of the start, but it is a nightmare.

The farmers who grow corn in the future, do not know that after the corn plant is stored, they become feed, they know that as long as they become feed, they can turn waste into treasure, can add a lot of added value, if we raise some animals, such as pigs, cattle, sheep, they have higher value, they can get high value.

However, the labor force of ordinary farmers is limited, according to the situation of the Navy, most of the manpower invested in industry, agriculture can use limited manpower, in general, a person is often cultivated 50 acres, or even 100 acres of land.

The use of mechanical equipment can allow one person to cultivate more land, but if you add green storage straw, it will increase the labor force several times, without more labor, this is almost impossible to complete the task.

Just 3 tons of straw, collected and transported, it consumes a huge labor force, not to mention the green storage, the need for more labor, in a person's 50 acres of the premise, this is a nightmare.

Straw can not be wasted, perhaps in the future, in the first batch of corn planting, the future, planting area, and then expand 100 times, the output of straw, can not be fully used, will be processed, but at present, only 2 million acres of land, certainly can be fully utilized.

The Navy has developed a certain method of making feed, and will carry out a series of arrangements according to the distribution of test fields, mainly divided into different sizes of feed bases.

The largest, of course, is a professional feed factory, they will bar in the corn pole, the most elite part of the processing, and then through the addition, the real feed of the city, this part, can supply the breeding base, as small, belong to the basic coverage, they are mainly green storage, auxiliary part of the feed processing capacity, they in addition to the feed itself, or a breeding base, large-scale intensive breeding, to ensure the use of green storage feed.

When thousands of experts, distributed on the land where many of the cultivation of corn, impart knowledge to these farmers, these farmers are full of disbelief.

They would not believe in any way that there would be such a grain, and their intellectual structure was far worse than these experts, but their experience in growing grain was higher than that of experts, knowing that they had been a good man of the dealer from before, so they came to the navy and kept planting the land.

Although it is said that after the Navy, it has risen a lot of insight, from the original maximum of 3.4 stones, increased to 5, 6 stones, but this is already the limit, even if they use a lot of methods, but also a little improvement, in order to large-scale promotion, it is impossible.

Now, tell them to give new crops, a seemingly strange crop, that they can increase their average yield by 50%, and most importantly, this is not the limit, this is only the initial degree.

For these farmers, the cognition that has been formed is difficult to change, and experts are well aware of this, so the evidence is used.

It turns out that the plants in the test field cannot be seen by everyone, but mature plants can still be taken.

A seed can harvest a corn, which is the vast majority of cases, and special, there will be two, or even three.

To the Navy, even the bottom of the farmers, they also know how to calculate, although the corn plant is very large, but in the land, occupy the position is not large, if calculated according to this plant, it is really possible to obtain such a high yield.

It is a simple matter, the next task, in relative simplicity, these farmers, their talent in planting, sometimes not after these experts, just know how to do it, can not say the reason, after a set of planting methods, soon familiar with the cultivation of corn.

Zhao Xin has always been very concerned about all the arrangements of corn, this matter, but also as a point, reporting up, when knowing these growers, questioning the corn production, he can not help but laugh out, where to go, if South America's three major crops, the most comprehensive effect is corn, his more effective, is shown in the breeding, corn all aspects of the plant, used to do feed, is natural, but on the grain itself, his output is not large.

The other two of the three crops, sweet potatoes and potatoes, are not high in the feed, more food, they are natural, unlike other fruit plants, sweet potatoes and potatoes, which are themselves root, this plant can grow larger and produce more.

An acre of sweet potatoes, an average of 5000 pounds, intensive cultivation, or good varieties, can even reach tens of thousands of pounds, in the future, more than 10,000 pounds has been seen.

Under the premise that the kilogram is already very terrible, it has increased to 10,000 pounds, and the data that can be converted into the Song Dynasty can understand, that is, 100 stones, what a concept.

Not to mention that those farmers do not believe, even those experts of the Institute, do not see the physical, will not believe that corn on the basis of the original, increased by 50%, is already a very high, the average yield of sweet potatoes, simply 8 times, the limit of the degree is 20 times, this is not a miracle, is scared.

The output of sweet potatoes is so high, it can be said that at the end of the Ming Dynasty, the early Qing Dynasty, the emergence of sweet potatoes, from trying to plant to large-scale planting, which increased the number of people, sweet potato noodles, sweet potatoes have become the bottom of the people, the product of the belly, saving countless lives, but this thing, eat too much, not very suitable.

The three major crops in the Americas, they all have such problems, most of them are not suitable for the Chinese gastrointestinal.

Corn, sweet potatoes and potatoes, even in the 21st century, are called healthy food, but if you eat for a long time, it is easy to get some diseases in the stomach.

No way, they have more coarse fibers inside, even after finishing, which will increase the burden on the stomach and cause gastroenteritis-like diseases.

In the middle, especially the largest production of sweet potatoes, this in the future, is called health, is called anti-cancer food, in fact, for the stomach damage is huge, long-term a large number of sweet potatoes, the gastrointestinal will appear problems, light will appear inflammation, the weight is the disease.

This, if it is placed in the famine years, no problem, even food can not eat, in order to live, how can you do,

But in the peace years, it is not, this is the future, afterlife, why wheat and rice is the world's second largest food crop, corn is only ranked third, and the yield of potatoes and sweet potatoes, is the lowest, it is because these physical universalism is not strong, long-term eating, easy to get a variety of diseases, to a certain extent, they are as a coarse grain, as a supplement the same existence, in the later generations, are not dominant, they are just some necessary supplements.

Sweet potatoes and potatoes, not in hand, or even to a certain extent, Zhao Xin understood sweet potatoes and potatoes, in this era, far from mature.

Corn, as the largest discovery of the Indians, planting time is also very long, as the main food of the Indians, there are thousands of years of planting history, in the long time, through the choice of generations, the survival of the fittest, only to form the present, perfect corn.

But sweet potatoes and potatoes are not the same, especially the latter, at this moment, or in the mountains of South America, he has not changed, has not become the potato of the future, whether it is yield, or nutritional value, there are great differences, just a foundation.

However, if you get it, in order to determine the level of the Navy's science and technology and agricultural planting level, they will soon find their real efficacy, and then, if widely cultivated, it will have a very good effect.

Unfortunately, these two grain, one distributed in Central America, one in South America, now, the fleet of the fixed navy, has been based in the Americas, built at least 10 ports, the most, has reached the position of the future San Francisco, but unfortunately, from Central America, from South America, there is a relatively distant distance.

The process of corn obtained proves that it is not easy for any crop to obtain, not where the ship arrives, it can be obtained, it must be step by step, stable and stable, under the great level of shipping, the development of most places, in order to find these things, left and right three goals have completed one, do not have to hurry, slowly just.
