Green storage feed, an important invention in the last generation, through lactic acid bacteria fermentation, so that some things that are not very suitable for breeding animals to eat, become suitable, reduce the input of grain, etc., increase the exchange ratio, after all, food crops, most of them are seeds, he is in a plant system, only occupies a small part, far less than the total amount.

Such an invention, so that intensive breeding has become a profitable business, this is the role of feed, later generations in the material is extremely rich, there is also the so-called feed out of the meat is not delicious, but the huge benefits, so that the rapid development of the feed industry, has become a very important industry, but also promoted the decline of various meat prices.

This decline is not a decline in the unit price, the relationship between inflation, the entire currency value is declining, and the unit price is gradually rising, but the ratio before the same general equivalent, we can see some clues, and the overall is declining.

The most suitable for green storage feed is the corn stalk, which is even the most important source of green storage feed in later generations, and also occupies a large proportion in the professional feed.

Corn is one of the three high-yielding crops in the Americas, the other two are sweet potatoes, the yield of corn is not as amazing as the latter two, potatoes are four or five thousand kilograms, and sweet potatoes are as high as seven or eight thousand kilograms.

The limit yield of corn is not low, the highest yield in later generations also exceeded 1400 kg, under normal circumstances, the use of some good seeds, can easily reach more than 1000 kg, agricultural scientists, through hybrid rice, barely reached a ton of grain field, not every can be reached, but corn can easily reach, is rice and wheat can not be compared.

The most important thing is that corn does not have the shortcomings of sweet potatoes and potatoes, it is more suitable for edible food, the planting area of later generations, second only to wheat and rice, is in the third place, it is a natural feed source, with corn to breed, the yield is higher than ordinary grain, the whole corn can be incorporated into the feed, the utilization rate of the whole plant is as high as more than 85%.

Corn itself, which is nothing, is corn on the cob, in the whole plant, may not even occupy one-twentieth of the plant, in terms of food, the yield of corn is already amazing enough, even more so in the feed, this total yield is much higher than potatoes and sweet potatoes.

In the whole plant of corn, the sugar content is not small, and even when there is a famine, corn sweetheart can be eaten, even if people can't eat it, livestock can also eat, at most it is not digested, green storage feed can solve this problem, and it will maximize the effect of corn.

In fact, the grain output of the Northern Song Dynasty was almost the same as that of the Qing Dynasty a few hundred years later, and the development of a large number of silt fields in the south of the Yangtze River exceeded the output of 4 stones, so that the grain in the Northern Song Dynasty was not too lacking, and it also caused an explosive growth in population.

At this moment, if the three major high-yield crops in North America can enter China, while increasing the basic grain, change the industrial structure, especially the emergence of high-yield grains such as corn and sweet potatoes, which are suitable for making feed, the population of the Northern Song Dynasty will further increase, and the equivalent change will reach the level of qualitative change, and the tragedy may not happen in the future.

Zhao Xin's infinite expectation is to be able to find crops in South America, whether it is potatoes, sweet potatoes, or corn, any of the three will change the food structure of the entire Northern Song Dynasty, especially corn, which is a god-given high yield, and its own yield is very high, corn itself is also the healthiest food, and the content of various nutrients is very high.

These three treasures, just like this, are widely cultivated in the Americas, and the history of the Indians planting corn may be more than 10,000 years, or even to some extent, much earlier than the history of wheat and rice cultivation in China.

Zhao Xin does not study world history, but some of the history of grain division is still very popular in international history, according to this division, Europe is called the wheat civilization, Asia is called the rice civilization, as for the Americas, it is called the corn civilization, especially in Latin America, which was once the core of the Mayan civilization, and later Mexico, even regarded corn as a totem worship like a deification, which is not seen by other civilizations.

With the current extensive planting area in the Americas, as long as you reach the Americas, you can obtain these seeds, completely change the grain structure of the Northern Song Dynasty, and completely solve the grain problem of the Northern Song Dynasty in at least a few hundred years.

The Romance of the Three Kingdoms wrote at the beginning that the general trend of the world, divided for a long time, must be combined for a long time, it seems that it is to summarize the law of the dynasty, but in fact, the changes of the dynasty are more related to food, land annexation, disastrous climate, will affect the changes of a dynasty, food is the fundamental problem, is human instinct.

If it is an animal, there is nothing to eat, either starve to death, or look elsewhere, people cannot, they have thoughts, hands and feet, they can give everything for a bite to eat, and this is the root of peasant uprisings and movements, their purpose is very simple, to eat.

The three high-yield crops, without much change, can more than double the yield, this total amount will be very large, the population that can be fed, will also increase a lot, even if it is the birth rate of the Northern Song Dynasty, it will take a long time to increase from 100 million to 200 million, which laid the foundation for the development of the dynasty.

Of course, the Northern Song Dynasty and the Southern Song Dynasty did not end up because of the peasant uprising, he was invaded by foreign enemies, but with food, food as a weapon, plus other adjustments, the power of the dynasty will definitely be stronger.

The three high-yield crops can be said to be a terrible species that changed the course of China, once obtained, it is strategic, and Zhao Xin also knows that in this era, it is impossible in a short time, because it is too far away and too difficult to get.

At this time, the Americas were still an independent, huge area controlled by the Indians, who established a magnificent and huge empire throughout the Americas, a series of large empires, established in the rich Americas, as early as thousands of years ago, had reached a considerable level of civilization.

The development speed of the Indians is too slow, as early as 50,000 years ago, an Indian ancestor located in Asia, crossed the Bering Strait, arrived in the Americas, what is the specific reason, so that the Stone Age primitive people, across the Bering Strait, it is said that during that period of time, the climate is warm, the entire Asian high latitude zone, not so cold, convenient for the Indians to cross.

More scientific experts believe that it should be the reason for the colder, in some time of the Quaternary, especially in the last ice age, the world's climate became colder, the ice came, the sea level fell about 130~160 meters, and the Bering Strait, which was only a few dozen meters deep, exposed a land bridge, connecting northeast Asia and northwest America, becoming a natural passage between Asia and the United States.

During the Ice Age, the climate in northeastern Asia was very cold, overflowing with glaciers, and the interior of the Americas not only had no glaciers, but also had a mild climate and abundant food, where many animals such as mammoths, elephants, musk oxen, moose, and sheep lived. It is likely that hunters in northeastern Asia, who hunted mammoths and deer for a living, followed these animals across the Bering Strait land bridge to the Americas, becoming the originators of ancient civilizations in the Americas.

In the era of the Northern Song Dynasty, the mainstream of the world was the yellow race, the yellow race occupied Asia, the Americas, almost occupied most of the whole world, the black people occupied a huge Africa, the white race, only a small part of Europe, Eurasia, Europe in the front, Asia in the back, that is because of the rise of the white people in later generations, the mainstream language and countries in the world are white relations, but in fact, Europe is very small, only a fraction of the size of Asia.

Between China and the Americas, there is a vast Pacific Ocean, which is so vast that it is like a moat, isolating the communication between the two sides.

It's not impossible to get there, it's just that the road is too far, on the one hand, you can take the path of the original Indian ancestors, take the overland route, go around northeast until you reach the Bering Strait, and then cross the sea.

The Bering Strait is the dividing line between the Americas and Asia, but it is the narrowest place, the narrowest place is less than 35 kilometers, and the widest is only more than 80 kilometers, which is not as good as the Taiwan Strait, the narrowest of which is more than 135 kilometers and the widest is more than 150 kilometers.

This harsh environment is the key, with the time of the Indians, the reality has changed too much, the high latitudes of North America, is still very cold, more than 70 degrees of dimension, is the permafrost zone, the day is getting more and more factory, the night is getting shorter and shorter, almost more than half of the polar day and polar night state, the natural conditions are too bad.

Even in the later generations, if you want to pass through the middle, it is difficult to achieve, in the later generations, although there are adventurers, with high-tech equipment, GPS, a large number of planes and helicopters as backup, you can call for rear support at any time, but every year there are idle egg-sore adventurers who die on the snow.

In fact, in Russia and Canada, places that exceed 65 degrees above the dimension are basically free-range, except for a few scientific expeditions and some personnel who have to stay there, there is almost no human interaction.

This is a forbidden area of God, even in the later generations, few people go to those places, perhaps the historical Indian ancestors, it took a few belts of time, slowly adapted, slowly walked, and finally came to the American continent, but to send a caravan over, it was almost a nightmare, and the possibility of being able to successfully cross was almost zero.

The harsh natural environment has made the high-latitude region a forbidden area for life, and even under the premise that there is a lot of support from future generations, this Jedi cannot be passed, Zhao Xin just thought about it, and did not put it into reality, it was impossible to complete.

Zhao Xin prefers the second way, ocean voyage, which is a more feasible method, of course, just as dangerous.
