Feed, this is the real role of corn in later generations, and even because of the large-scale planting of corn, not every corn stalk will be used, treated as feed, and even to a certain extent, incineration is the only option.

Incineration, I am afraid is the use of crop straw, the simplest, but there is the most low-level application method, plant ash, contains a certain amount of fertilizer, bury it in the soil, can be a certain extent, increase the fertility of the soil, but this increase is very little.

Most of the tissues, proteins, and other beneficial components are burned through incineration, and even this kind of vigorous burning activity will make the heat impossible to utilize, and a large amount of straw smoke, as well as carbon dioxide and the like, will also pollute the environment, which is its disadvantage.

But there is a little bit, convenient, as long as the corn is harvested, the straw left in the field, a little dry, ignited, so as to save time and effort, other kinds of processing, are more wasteful of effort, maybe there is a feed mill around, will also buy some in the periphery, but a little farther, the freight can not be drawn, can only be wasted to the ground.

Of course, Zhao Xin would not do this, in this era, he has a strong control over the entire country, and his orders are the highest instructions.

Although this order was issued without a head, plant experts, after a little thought, especially a simple calculation of the weight of the plant, you can know that this number is extremely terrifying, according to the ordinary calculation, the current navy, need 15 acres of grassland, to be able to feed a cow.

15 acres is definitely the limit of the degree, must ensure that the water and grass are abundant under the premise, can be achieved, the same, this is only a year, especially the first year, cattle and sheep for the grassland is too destructive, often to double, or even more can, but after the corn, you can 3 acres of land to feed a cow, this for the development of animal husbandry, too big.

This is also the ultimate effect of corn, in later generations, corn more, not as a staple food, he is often an industrial raw material, for example, to make alcohol, and other chemical industry raw materials, at the same time, he is also the basis of animal husbandry, after the green storage, or simply through a certain processing, processed into feed, is the best choice.

Now, the Dinghai Navy, in the Dinghai Navy, and the centralized aquaculture industry implemented in the Northern Song Dynasty, more is the use of grain as the basis, once the corn is used, plus green storage fodder. Corn is only incidental to the grain, and real breeding is the end.

According to the beef cattle to calculate, basically 3 years 1000 catties to calculate, per mu of corn can produce more than 100 catties of meat per year, this is 1 stone, and now, the method of grain calculation, are more than 3 times, the average of about 4 times. In this sense, the efficiency of corn should be doubled or even more.

In this way, the yield of one acre of corn is higher. It could be twice as much, or even more.

Grain experts, did not think so much, but after the introduction of animal husbandry experts, after 20 days, the green storage was done, and the green storage of good feed was fed, only to find that compared with the ordinary green storage, this has exceeded the vast majority of the green storage feed, it can be said unceremoniously, this effect is equivalent to the previous green storage feed several times,

The characteristic of corn is that it contains a large amount of polysaccharides in its rhizomes, and there are some substances that can be eaten by cattle and sheep.

The experiment of corn production, coupled with the advantages of animal husbandry, has suddenly raised the level of corn, from a revolutionary species to a pillar species.

This batch of corn, or even the next batch of corn seeds, is crucial, the first batch of 5 tons of products, produced a 200-fold increase, reached 1000 tons, and the follow-up, a series of inputs, a total of about 100 tons, finally, less than a year, increased to 14,000 tons, according to the standard of 7 catties planted, 7 tons is 2,000 acres, the first batch of seeds, about 2 million acres, this is basically, is the largest amount of land that can be adjusted in the north.

Under the approval of plant experts, under the stroke of Zhao Xin's pen, 4 million acres of land were immediately selected for corn planting, and in the future, according to the situation, continuous research, and constantly expanding the planting area, in order to ensure food production, at the same time, also to ensure the continuous development of animal husbandry.

A single corn has such a terrible effect, after a little emanation, at least in the middle and upper levels, for the investment in the Americas, gradually, no one to say.

Even now, compared with grain crops, corn can definitely be regarded as the king, and the important role of grain is gradually revealed, and the benefits to the navy are huge.

In itself, Liao is a traditional animal husbandry area, the number of cattle, sheep and horses is huge, the Ding Navy on the basis of the Liao State, and improve the number of breeding, for example, more scientific, green storage and captivity, so that although it is said that the production of breeding surges, the current Ding Navy control range, the number of cattle, sheep and horses, almost more than the limit of Liao 4 times, although it is said that a variety of methods have been used to solve certain problems, but it is inevitable that in the long run, the grassland will be degraded.

There is no way, the grassland is limited, and under the premise of population and all aspects of improvement, those who continue to ask for nature will inevitably be attacked by nature.

From the very beginning, when the island was developing, Zhao Xin paid great attention to the problem of sustainable development and pollution, and he would not do extinctional development and development in his spare time, because he knew that the population was too dense, and once the extinction development polluted the environment, he would definitely take out a thousand times, or even a hundred times, to make up for these in the future.

For example, if pollution is discharged into rivers and lakes, it may take several years or even decades to be repaired, but once it enters the sea, unless it is dilutable or degradable, most of it can be repaired by nature.

As long as it is not a long-term, long-term overgrazing, once there is something else to replace it, it can recover naturally.

Of course, Zhao Xin knew this, but in the early stage of development, he couldn't deal with this at all, plus he also had a regular promise for the three major crops in North America, so he chose this method, as long as he could live the three major crops in the Americas, to be exact, as long as he could live corn, then everything would not be a problem.

Now, corn obtained, to a certain extent, with corn, it represents the stimulation of animal husbandry, the value of feed contained in corn plants, through deep processing, green storage and a series of ways, added to the feed, improve the yield of various animal husbandry, at the same time, some lack of things, can be replaced by bone meal, fish meal, etc.

Fish meat, not everyone likes to eat, but fish meat from the ocean, can be regarded as another gift of nature, at present, in the entire ocean, under the premise of rich fish resources, only the Chinese take action, choose not destructive fishing, can support for a long time.

Compared with the more valuable cattle, horses and sheep, the processed powder of fish can become the main source of protein, and after digestion and absorption through animal husbandry, it becomes what the general public likes to eat, which is also a kind of conversion.

In fact, whether it is food production or meat production, it is a process of transformation, and how to make it more affordable is the key.

At this point, no crop, a plant, can be compared with corn, even if it is called the best alfalfa of animal husbandry, can not be compared, there is no such a product, in terms of grain and feed, and corn is perfectly combined, corn is also because of this, has become one of the most planted food crops in later generations.

3 acres of land can raise a cow, or a few sheep, but from this point of view, the harvest of meat is already quite considerable, which is a way to combine agriculture and animal husbandry.

Before, there were only a few tons, up to 100 tons of seeds, and now, the number of seeds exceeds 14,000 tons, which can supply 2 million acres of land for planting.

The planting of the first batch of corn is specially drawn, and it is calculated that it is more suitable for corn growth, not to mention drought, even if the land is a little barren, it will not be chosen.

At the same time, ordinary people, farms, are not familiar with the cultivation of corn, which is a grain from North America, which is completely different from most of the crops grown in northern China before, and how can it be successful if there is no one to guide it.

This was also taken into account by the Institute, because of the complexity of the corn, organized by the experts of the Institute, and some of the farms, which did not provide a great deal of scientific guidance, but also provided quite a lot of equipment.

It is clear that in such far more than ordinary means of planting

With the help, the cultivation of corn was, of course, a complete success, and the location they explored was at the junction of the United States and Canada, where the dimension was similar to that occupied by the current Dinghai Navy, and the seeds were not adapted to temperature, and they had been cultivated by the research institute, at least, at the seed stage, which was quite good.

Zhao Xin, not only provided seeds, but also provided planting methods, this planting method, is not the research institute research, although the Dinghai researchers, has formed a scientific system, all aspects of research, has reached a considerable extent, but with the later generations, with the 21st century, after hundreds of years, or even longer training, for science and agriculture to understand the deeper planting methods, I don't know how much worse, even Zhao Xin does not know the skills inside, but take the doctrine, Taking all these experiences and directly handing them over to these people is of course gratifying in the final result.

It took a very short time to complete the training process, and all aspects of the needs of corn have been met, and the only thing that is lacking is some fertilizer that is specially used on corn in later generations. This can be replaced by a combination of chemical fertilizer and green manure, there may be some differences, but the difference is not big.

The research of later generations is on a certain peak level, and then to a higher level, it seems that the yield per mu exceeds 1500 catties, but this is not a single item can reach the degree, if it is simply on a single item, a single item more than thirty or forty catties is good, but all the individual items, in all aspects have made efforts, superimposed, it has produced a multiplication effect.

Dingjun now, the whole agricultural technology, is still a relatively low degree, not to mention compound fertilizer, even if it is a chemical fertilizer, it is also the most basic kind, for planting technology, for seed optimization, there are many results, in this case, talk about what more advanced compound fertilizer, completely extinguish meaningful, first solve the problem of whether there is.

In the same way, such a first batch of corn will produce good results, and even the yield will be very high, for the simple reason that some pests and diseases of corn are not available in this era.

You know, this is the first batch, some local animals, have not yet developed the habit of eating corn, and some pests that specifically target corn have not evolved.

This is the same as the rabbit in Australia, he is an advanced species, and after arriving in Australia, he has no natural predators, and his breeding is terrible, which becomes a terrible war.

Of course, the corn can't hit that level, but the first batch of plants has a terrible effect.

In the laboratory, the sowing of one acre of land was 3 catties, and in the end, it reached a 300-fold increase, and the pasture reached 900 catties. Under the premise of promotion and field planting, such an effect may not be achieved, but the planting of one acre of land has reached 7 catties, and in the end, the return ratio is about 125 times.

The yield per mu is close to 900 catties, which is also the highest yield in the past so many years, whether it is a small field or a large field planting. At least 8 stones, or even close to 9 stones, some more suitable, up to 10 stones, this is simply a fantasy, if you don't see it with your own eyes, almost no one will believe it, it's true.

Chinese, maybe directly eat corn is not good, Chinese's stomach, but also to adapt to such food, but in the tube full, there are similar Chinese practices, cornmeal, corn grits, corn cobs, etc., after these practices come out, there is not much problem with filling the stomach.

With these, China's food security, to a considerable extent, is guaranteed, if combined with the reasonable use of green reserves and feed mills, to a certain extent, the yield of one mu of corn is very amazing, these will jointly build into the food security foundation of the Dinghai Navy.
