In the final plan of the navy, this feed mill is positioned as a production capacity of 500,000 tons, digesting feed for about 360,000 tons per year, that is, 120,000 acres of radiation range, and then in the corresponding range, there will be some small, annual processing capacity of about 50,000 tons of green storage feed farms, combined with each other, not that can increase the efficiency of processing, at the same time, will let some corners also take care of, as far as possible to reduce the waste of straw.

With a small feed mill as the core, and then assist a batch of green storage feed factory, you can complete the edges and corners, and process the feed products, at the same time, this part of the green storage feed factory, while manufacturing feed, is a farm.

In the future, with the expansion of the planting area of corn, when the planting area of corn expands to 200 million, 300 million, or even 500 million, a large number of large-scale feed mills will be built one after another, but now, under the premise of 2 million acres as the base, the current scale is enough.

The construction of the feed mill was started more than half a year ago, and as for the training of employees, it was even earlier, even if there was no large-scale raw materials, Zhao Xin would let this move be carried out in advance, not to mention, there were materials provided by the test field, perhaps these materials could not be supported, large-scale, high-speed production, but the training was enough.

Small green storage feed factory, the main breeding objects are pigs and chickens, this is proven by later generations, the easiest to do, and the easiest large-scale captive breeding methods, similar experience, has been popularized, now, is just waiting for the straw harvest, and then the breeding method to summarize, not to mention to achieve the most efficient breeding methods, at least, will not produce omissions.

Just when the corn in the farmland is gradually maturing, these feed mills and farms are also gradually arranged in place, waiting for the corn to be harvested, which is when these factories are opened.

Corn harvesting, is in front of the Mid-Autumn Festival, the north belongs to the land of the Dinghai Navy, except for a few places, most of the places, the dimension is quite high, in the high latitude zone, after the Mid-Autumn Festival, it is easy to have the invasion of cold air, often after a cold air invasion, the temperature will plummet, some extreme weather, after the Mid-Autumn Festival, it is easy to produce freezing, or sub-zero weather.

Although corn is said to have the ability to resist drought and cold, but on the land of Northeast China, endless cold air, and even occasionally, sub-zero temperatures abound, corn is above zero, it is easier to do, once it is below zero, or even many degrees below zero, it is a huge harm to corn.

Corn is a first planting, has not been researched, the tool for harvesting corn, when the thresher, was taken out by Zhao Xin, not that Zhao Xin understands, but in the 21st century, when the farm is busy, he has used, of course, manual, so that it is better, the mechanical and electric power above the conversion.

As for the tools for harvesting corn, in later generations, some combine harvesters, equipped with knives that specialize in harvesting corn, can still harvest corn, but at that time, Zhao Xin was in the mountains, and large machinery could not come up, and some people were willing to go, but only slightly knew.

Zhao Xin will also draw some graphics, but unfortunately, just on TV, I saw it from afar, and I didn't feel it, how much difference there is between this harvester and rice and wheat, at most, take it out, as some basic forms, because the switching function of the combine harvester in later generations can be said to be similar to wheat and rice, but it is just a matter of height and knife cutting.

This was distributed to the laboratory, and the laboratory under Zhao Xin's suggestion, on the basis of wheat and rice harvesting tools, still got some harvests, but there is still a distance from the finished product and the real application, but it is finally moving forward, and in the future, there may be two or three months to make more practical tools.

But this harvest is still not good, in the first harvest, it is still necessary to focus on manpower.

The labor intensity of breaking the grain is smaller than that of harvesting rice and wheat, for the simple reason that corn grows in a high place, and there is no need to bend over or cut it with knives, but it is still a labor-intensive labor without using simple manpower and tools.

Anything related to food security will be valued by Zhao Xin, not to mention corn, a vigorously promoted crop, this year's 2 million mu, most of which are to be made as seeds, unless there are some congenital deficiencies that cannot be used as seeds.

These are not a lot, if we say, according to half of the calculation, next year, the planting area of corn will be expanded by 60 to 70 times, reaching between 120 million mu and 140 million mu, so that the calculation is basically met, in the next 3-5 years, there will be no comprehensive retention, but in the middle of the selection.

At the same time, the breeding and research work in the experimental field is also being carried out, and the improvement of improved varieties is not something that can be completed in a short time, but must be carried out for a long time and after many generations of research, so as to stabilize and solidify some evolutionary directions, so as to achieve the purpose of increasing production and income.

There were many farm workers, and some volunteers, mainly from the city's idlers, students and soldiers.

In Dingjun, the male work system adopted, generally speaking, in principle, does not support women's work, but at some critical moments, such as when the farm is busy, it is still possible to recruit some healthy women to help, especially the corn harvest, which is less labor-intensive, and at the same time, in some schools, more than 14 years old and half children, they are actually not much worse than adults in terms of labor ability, they are also an important part.

2 million mu, even if it is 3 mu per person per day, a total of 10 days, a total of 60,000 people, that is, 60,000 or 70,000 people, this part, in the Dinghai Navy, can not make too many waves, not to mention a large city with a population of tens of millions like Shenyang, even if it is a city of more than 500,000, a little care, can also be completed.

This is still this year, 2 million mu, just a small batch of production, at most a little increase in production, but next year, at least 120 million, between 140 million, that is to say, the planting area, at least increased by more than 60 times, then in a certain sense, if there is still no harvesting tools, the number of harvesters will also increase by 60 times, that is, 3.6 million people.

Even if the navy is now fixed, with a population of more than 80 million, it is very difficult to transfer so many people in a short period of time.

The reason why human beings, with their modest bodies, have become the rulers of the earth and built huge cities and landmarks is that they use tools.

From the first stone, bronze, and iron tools, to the machines of the Industrial Revolution, human beings have used such tools to understand and transform the world.

Why is it that in ordinary peasants, they hold on to death, even if they work until death, that is, cultivate one or twenty acres of land, the reason is that manpower is always exhausted, and relying on manpower alone, there is no way to plant 50 acres, let alone 100 acres.

This is unlikely until mechanization is widespread, but the Navy can use large-scale cultivation.

The land is through the scale, is flat, connected into a large plot, at least 10,000 acres of starting, some larger, better blocks, can even reach 100,000, or even 200,000 acres.

In the vast amount of land, with the help of large ploughs and a large number of livestock, it is possible to produce efficient cultivation and harvesting, so that the degree of mechanization has reached in disguise, and on average, each person can afford 50 to 100 acres of land.

If we say that next year, when the corn harvesting tools are out, when harvesting, the manpower used will be more than usual, under the premise of 120 million mu of heavy quality, the manpower consumed will definitely be more than this year's 60,000 people, but it will certainly not reach 60 times the degree, and there can be two or three hundred thousand people, which is about the same.

In 10 days, more than 60,000 people, through hard labor, although for the farm, harvesting one acre of grain is not a few dollars at all, but this is all manpower to harvest, and it is the first batch of planting, in terms of measurement, a little higher, according to the average daily wage of ordinary workers, the harvest price of one acre of land, is set at 2.

This is a terrible number, if it is placed in the Northern Song Dynasty, even if it is the most difficult to harvest grain, the labor cost of an acre of land can be 50 Wen, which is already good, and the salary of the navy is high, and the price is inevitable.

Of course, the wool comes out of the sheep, the farm will lose, no, although this batch of corn harvest, most of the need to keep seeds, but a small part, can still flow into the market, this part, about 2-3 stones per acre.

Anything is scarce, when it is scarce, the price will be relatively high, once, at the end of the Ming Dynasty, when there was no large-scale planting of sweet potatoes, the price of a sweet potato was even as high as 1 tael of silver.

Dingjun is a high-income, high-welfare society, the average monthly salary of the entire Dingjun is about 300 yuan, take out more than a dozen yuan, try it, this is everyone will do, which provides a broad market for the sale of corn.

In fact, the ones with full grains and better genetic information were singled out, and a small number of those that were not too full were left and sold in the Dinghai Navy.

The whole plant is relatively intact and grows slightly better, which can be eaten as a cob, boiled, or roasted. A little worse, can be made into corn kernels, the worst, is corn grits, so the combination of the three, began to be sold on a large scale in Dinghai.

In the world of the 21st century, boiled corn has a large market, not to mention this era, corn is a completely different grain from rice, wheat, and tastes unique, plus it is rare and expensive, which immediately triggered the sought after, the initial price of a corn cob is 1 run, but soon, it can't stand people's pursuit, and it has increased to the extent of 2 and 3 runs.

You must know that one acre of land, at least about 2,500 corns can be planted, and what is really sold is only about one-third, which is 800 corn cobs, even if it is according to 1 run, that is, 800 runs, the income is amazing, if it is according to 2 runs, 3 runs, it will be more.

Including Zhao Xin also knows, this is not a long-term business, is expected to next year, along with the number of corn planting, reaching 120 million mu, according to the output of 8 stones, is close to 1 billion stones, this part of the retained seeds, most of them are to be put into the market, 100 times the number of impact, the price of corn will have a relatively large fall, not to mention falling into a blank paper, but will fall its reasonable range.

For example, in later generations, the price of polished rice is generally 3-8 yuan, and the price of flour is more than two yuan, but the price of corn grits and the like is generally more than one piece.

Although it is said that there is a big difference between the navy and the future generations, this proportion should be the final proportion under the basic income ratio.

The harvest of corn, as well as the sale of corn, is very much the name of corn, in the Dinghai brushed, enriched the Dingjun grain market at the same time, but also stabilized the grain of the Dinghai, as long as the corn planting range is expanded, even if it only occupies one-third, it is equivalent to saying that the entire grain output increased by more than 3 percent, which is quite stable for the Dinghai Navy, which is quite stable in its own food security, is the icing on the cake benefits, however, the greater benefits are still to come.

The emergence of a large number of straws, as well as the emergence of feed mills and green storage farms, so that the livestock production of the entire Dinghai Navy has produced a blowout, and the grassland produces a lot of various livestock.

However, for the northwest is a wave of fertilizer, for the Dinghai Navy is different, the grassland can accommodate millions of livestock, relative to the volume of the Dinghai Navy, the degree of daily consumption of meat, the difference is too far, the amount of animal husbandry that the grassland can bear, simply can not be compared with the centralized breeding, centralized captivity, reduce the activities of animals, to a certain extent, will increase the meat rate, under the premise of a certain degree of total, this growth is also very considerable.

In the past, there was no way, there were no raw materials for feed, even if you know the method of production, you can only watch, now, with the planting of a large number of corn, it is said that 2 million acres of small batch planting, will produce 6 million tons of green storage feed, if it is made into feed, add other things, this number will grow, which gives large-scale captivity and intensive breeding, laid an opportunity, and the era of popularizing meat in the navy has finally come.
