Corn was found from the Americas, and by the clipper ship back to the Dinghai time, it has reached the middle of the year, corn is used as the existence of autumn grain, generally speaking, can not be wintered, the cold will make it inactive and die, this is the root of planting corn, at the same time, relative to wheat, rice, not to mention in the south, in the north, the growth period is relatively short.

More than 10 days, a little more than four months, which is something completely new for most farmers who have grown wheat and will take time to get used to.

Fortunately, the laboratory, the Institute of Agricultural Sciences, and some agricultural experts have given comprehensive guidance on the planting of corn, which is all-round and covers all aspects of the entire planting.

Although it is said that in the planting of 2 million acres, there have been certain problems, and there are some mistakes that have caused a reduction in yield, but on the whole, the whole rise is very gratifying.

Before, in the teachings of the experts, and in front of the examples, they accepted with half-belief that they themselves were food growers, that they were workers, not peasants, and that there were no peasants in the traditional sense under the strategy of the navy.

After the Dingjun occupied the Liao State, because of the blows to some big nobles and the redemption of some ordinary homesteaders, the land in the hands of private individuals was very small and almost negligible.

When the government took control of the land on a large scale, and began to cultivate the land in a regular and orderly manner, the whole Dinghai existed in the form of farms, and these workers were paid monthly wages, of course, if the grain was grown well, there would be bonuses, but this bonus, in the whole proportion of wages, only accounted for 30%, and in addition to the horizontal comparison, basically, the fluctuations were not very large.

This is something from the top down, and it is valued by the Navy, so it is still planted seriously.

All of these people are very experienced, and have been scientifically cultivated, and are very experienced in planting, and the new product of corn, once planted, will show its characteristics after continuous elevation.

In the seedling stage, it is a little different from ordinary food crops, after constantly pulling up, pumping, it is even more so, compared with ordinary food crops, small leaves, small plants, this corn plant is very huge, huge leaves, constantly doing photosynthesis, more huge rhizomes, from the land, keep extracting all kinds of nutrients, and finally, concentrated on the fruit.

In the experimental field, they are the first time, it is some planting methods given by Zhao Xin, even if there is experience, there are scientific research methods, but in the end, there are still mistakes, under the scientific method, gradually research, revise some basic methods, and finally, form a regular method.

This rule, not all the rules, in the future, will be accompanied by continuous research, continuous planting, and gradual revision and change, and eventually, a systematic method will be formed, and all farm methods will be continued.

After more than 3 months, under the concentrated management of the whole farm, in most of the fields, the corn rose very gratifyingly, and almost every plant had a large corn cob.

Among the crops, it is not that there are no crops that are larger than the corn cob, but among the grains, such a growth method is really very rare.

In this way, wheat and rice are two kinds of grains, wheat and rice, both ears of rice or wheat grains, they are thirty or forty or fifty or sixty times the multiplier, but corn, on a piece of corn, how many corn seeds, at least one or two hundred, this multiplier is naturally determined.

The real situation makes them have to believe that such a kind of grain, it is really outstanding, this is the first time to plant, but when planting seeds, they have made certain calculations, knowing the weight of seeds, and measuring the rise of corn, it is really not an exaggeration to say that it is the yield of 8 stones.

Ready to harvest, eight stones per acre, at the same time, this is also a brand new product, it is certainly impossible to use machinery and equipment like the previous wheat, reduce manpower, for this reason, the entire Dinghai Navy, not only from other farms, but also the army, reserves, transferred personnel, ready to deal with the autumn harvest of such 2 million acres of land, at the same time, also from the major feed mills to draw a large number of personnel.

From the first batch of corn landing, to now, large-scale planting, almost a year, from the corn ashore began to prepare, after the completion of planting in the experimental field, the first batch of research and experiments, and then, one after another, in Dinghai, opened a large-scale factory system, feed processing plant.

Through scientific formulation, reasonable layout, and industrial methods, the production of professional feed, to cope with the use of different varieties of livestock, this will be the traditional, by each family, small workshop like the same production mode, to intensive, factory mode of transformation.

The method of industrializing the large factory is a huge improvement for all kinds of industries in the past, and after certain adjustments and plans, the entire Dinghai Navy has also made changes, from the original various stocking types to centralized offerings.

Feed livestock, which in later generations, is a derogatory term, and the first thing that comes to the mind of the buyer is that the meat quality is not good.

It is true that under the premise of feed breeding, or the addition of too much feed, in terms of meat quality, they are very different from the original, not as delicious as the original, and the taste is not good, which is also the reason why such feed breeding is not sought after in later generations, but in the early days of reform and opening up, when China gradually developed, this can solve a big problem.

Only after the use of feed, will the meat output show an increasing trend, this is the same as the improvement of chemical fertilizer for food, in the 21st century, under the premise of the gradual development of science and technology and life, people began to pursue higher quality, safer meat, but before that, before the problem of training has not been solved, it is necessary to increase the output.

After the treatment of the feed, than the direct eating of grass is more efficient, not to mention the difference in nutritional value, just say that edible, eat feed compared to grass, at least half of the degree, this alone, for farmed meat, is quite useful.

If it is only in the experimental field before, planting one or two hundred thousand acres of corn, even if they produce 3 tons of straw per mu, it is only tens of thousands of tons, green storage, experiments, and research will consume a lot, and finally help the feed factory to complete the overall positioning, and finally complete the design, which has played a considerable role, but this feed factory has not been built on a large scale.

Like the cotton textile industry before it, as well as other textile industries, the foundation of these industries was opened after the cultivation of cotton reached a certain level.

This is the inevitable process of raw materials for plants, when a raw material can not be provided, under the premise of working for a few months a year, or half a year, it is a waste for the machinery and equipment of the entire factory.

This is true for cotton textiles, and the same is true for feed, and it is a waste to build a large number of feed mills before large-scale corn planting.

Although Zhao Xin knows that the feed mill in the future is an industry with huge prospects, and even huge expectations, in later generations, it has even produced many of China's richest men, but before the large-scale planting of corn, forcibly opening the feed mill is not the best choice.

During the whole year, there was no physical object at first, just some plants in the laboratory for research, and after the experimental field was harvested, almost 50,000 tons of straw, not too much, not too much, at least in the laboratory is enough, small-scale promotion and production, is also enough.

In the laboratory, after more than half a year of research, and through small factory production, a lot of experience has been accumulated, a systematic and complete production method has been formed, and then large-scale cultivation has begun.

50,000 tons of straw is nothing, plus various other raw materials, about 70,000 or 80,000 tons of feed, this for cattle, a year, it takes one or two tons, 780,000 tons, that is, to feed 780,000 cattle, this is in the individual, and even some companies to the extent, it is already very large-scale, but for large feed factories, for some national monopoly breeding enterprises, it is really not a large number.

But when the number of plantings has increased to 2 million mu, according to this output, the output of feed may increase to 6 million tons, which is quite amazing, if you raise cattle, it is enough to breed 3 million heads, if you raise pigs, there will be more, as for poultry, it will be more, this is a huge industry, and in the future, there will be more.

Zhao Xin has a complete plan for the cultivation of grain, and now the cultivation of corn has reached the limit, not because of the land, but because of the seeds.

For the first time, more than ten tons of seeds were obtained, and after the planting of experimental fields, a total of 14,000 mu were planted, and after the terrible rate of corn appreciation, it was finally expanded to 2 million mu, and if this number is said, by this year, once these corn are harvested, all of them can be used as seeds, which can be expanded to 300 million mu.

Although this is not planned by Zhao Xin for the navy, the limit of corn planting area, the land controlled by the navy, the area of cultivated land in the future will reach between 1.4 billion and 1.8 billion, and it is expected that one-third will be planted with corn.

In this way, the total is about 500 million mu, according to the output of 8 stones, that is, the annual output of 4 billion stones, according to 8 stones per person, simple corn can feed 500 million people.

Dinghai will definitely not rely on corn for feeding, the same weight of corn, purely in terms of nutritional value, is certainly inferior to wheat and rice, but it is a stable foundation, if there is a big problem, there is a corn reserve as a basis, there will be no food crisis.

Similarly, in addition to feed, corn has many industrial products, alcohol, and their basic raw material is corn.

If there is continuous research on food, in the chemical fertilizer, organic fertilizer, and various scientific breeding methods, under the premise of continuous advancement, grain output will continue to increase, and 1.5 billion mu to 1.8 billion mu of grain is enough to feed most of the population, at least before the population of the Dinghai Navy exceeds 1 billion, there is no problem.

This 15 to 1.8 billion simply refers to the north, the original Liao, Japan and North Korea, as well as the land on many surrounding islands, without adding the land in Southeast Asia that is being attacked in the south, just one Indonesia, there are 450 million acres of land, too much more than 200 million, and the whole Southeast Asia combined, also more than 1 billion, the most important thing is that this is tropical land.

China has 9.6 million square kilometers of land and 1.5 million square kilometers of arable land, so that 1.3 billion people can be fed.

Indonesia is only 330,000 square kilometers of arable land, it supports a population of 250 million, or there is no large-scale fertilizer, and the premise of scientific planting, this is the benefit of the tropics, three crops a year, four crops a year, the overall output is very amazing, not only to ensure the use of the country, but also large-scale exports.

That is to say, in the future, if Southeast Asia is used as a granary, China will not have to worry about the food problem for a long time, and then after ensuring food and clothing, the food problem will be raised.

2 million mu, with a total output of 6 million tons of straw, plus other ingredients, may produce about 8 million tons of feed, which is very large and can have a huge effect on breeding.

Given the current level of science and technology and research of the navy, perhaps, it is difficult for a feed factory with an annual output of 8 million tons, but there is no problem with an annual output of 4 million tons or 2 million tons.

The efficiency and cost of large factories can be well controlled, but they can't do this because of transportation problems.

In this era, even until the end of the 19th century, the Dinghai Navy has solved the problem of transportation very well, but this solution is only in the linkage between trains and water transportation, and in the short-distance range, it is not a very good solution, but only relies on small boats, horse-drawn carriages, and ox carts to solve it.

The reason why straw in the 21st century has not been fully applied is, on the one hand, that the output is too large, and the entire Chinese feed factory, combined, may not be able to digest it completely, so it is natural to have a part of the waste.

On the other hand, it lies in transportation, if it is too far, when the freight exceeds a certain limit, the cost of feed will rise, which is not in line with the positioning of feed, and some are not easy to transport, it is easy to be abandoned.

In the 21st century, there is such a problem, in this era, in the absence of motor vehicles, let alone tractors and other things, short-distance transportation has become a huge limitation, then the feed mill must be adapted to local conditions, it is impossible to build too big.
