Dinghai has begun, large-scale expansion of the shipbuilding industry, all kinds of wood, has been in place, in the Dinghai built a large number of drying rooms for processing, compared with the original treatment method, I don't know how much improved, in a short period of time, can form a large-scale ship materials.

As for the material of the keel, it is not a problem, the steel keel, quite heavy, a weight of at least a few tons, which is a very difficult task for the former blacksmith shop.

One or two, maybe it's okay, if there are really more, then it won't work, but the steel mill of the Dinghai Navy has an annual production capacity of 2 million tons, and under such a production capacity, even if 10,000 tons are moved out for the casting of keels, thousands of ships can be built.

The gap in the navy, that is, this number, as long as this dock is made, it will definitely be able to solve the problem, and what the navy lacks is time.

But even Zhao Xin didn't expect that this contradiction would come so quickly, when the population of the Dinghai Navy exceeded 1.6 million, the food problem began to appear, if it wasn't for Zhao Xin to get the news, urgently transferred a batch of grain from Jiangnan, and purchased a batch of old grain from Haizhou, I am afraid that the Dinghai Navy would be in chaos.

The food problem is always a big problem, and this is especially true for islands like the Dinghai Navy, which have no foundation and are surrounded by no grain-producing areas.

Although the crisis has been solved, the discerning people are afraid, how this contradiction is produced, they know very well, that is, the contradiction between the population and the bearing capacity of the navy.

At that time, it was proposed to limit the population entering to ensure the needs of the entire Ding Navy, which was decisively rejected by Zhao Xin, and now the development of the Ding Navy, anyone can see that the population is the promotion of the Ding Navy, not to mention him, he came from later generations, he knows too well the importance of the population, not to mention the role of the population in industrial production, it is said that a group of middle class has been cultivated, and domestic sales can promote the hematopoietic progress of the industry.

Taking a step back, it may be the best choice, but taking the risk of moving forward, so that the population base, in the current state, to maintain a state of expansion, can accumulate several times more strength than before, although it is said that now, the Northern Song Dynasty has not yet discovered the disadvantages of a large number of people attracted by the Dinghai, because the Dinghai only attracts one or two million people, but when this number increases to four or five million, or even tens of millions, the impact will definitely appear.

Zhao Xin not only vetoed their proposal, but also set up a special department to ensure grain after that.

Starting from grain, to all kinds of non-staple foods, and even in the market, some simple macroeconomic regulation and control have been carried out, which has reduced some unnecessary waste and increased the efficiency of grain use.

Zhao Xin's move, at the very beginning, made many people feel puzzled, the industrial capacity of the navy is very strong, because of the restrictions, it can not accommodate so many people for the time being, and at present, several industries of the main body occupy a lot of output value, but the labor occupied is not much.

After a year of operation, the remaining population has been basically digested, but it is difficult to solve all the new population.

Now the increase of more than 600,000 people, seven or eighty percent of them, are undergoing targeted training to cultivate certain skills, and after the training, a small number of talented people, the rest, will be sent to temporary positions.

Temporary positions, which means that the non-permanent organs, are different from other places, and for industrialization, they adopt the thinking of later generations, do not support idlers, and every step is as streamlined as possible, reducing labor consumption and increasing productivity.

This kind of temporary position, more, is a helpless choice, the factory is so big, the investment plate is so big, just place some people, it is quite simple, but such a placement is equivalent to a kind of waste, not necessarily a loss, but will increase the operating costs of sorting, coupled with the contradiction of the food problem, so forced, in fact, is a kind of regression.

Zhao Xin is very clear about this, lower costs, more output, this has always been the profit of the navy, if you give up this profit, maybe there will be a problem with the navy's industry.

Forced orders, sacrificing certain interests for a short period of time, for a certain goal can be, but in the long run, no one can stand it.

There are no eternal contradictions, only eternal interests, and the results obtained by the generations after countless struggles, as long as everyone has interests, some sharp contradictions can be alleviated.

Of course, Zhao Xin knows that he hopes that the growth of the population and industrialization need the support of the population, hundreds of thousands of people, millions of people, it sounds like a lot, but it is really very little to really invest in industry.

If Zhao Xin simply puts his mind on Dingjun, let alone a population of 10 million, a population of one or two million, it is already good, surpassing the population of Bianliang, and then getting out tens of millions of people, it is purely to increase the burden.

In the future, what Zhao Xin wants to establish is the entire industrial system, which is all over the entire industrial system of the Northern Song Dynasty, and the personnel needed are not a little bit, 10 million is just the foundation, and in the future, twenty or thirty million will be normal.

This also means that the entire Northern Song Dynasty, to a certain extent, the young and middle-aged population, will be included, and the power of the industrial system formed in this way will be very terrible in the 11th century, and it will directly transform the Northern Song Dynasty.

This is the goal of Zhao Xin's efforts, since as a traverser, he also has the treasure of the card system, why not fight it, but a series of problems arising from it, it is difficult to predict, in order to smooth the transition, in the middle, there is a lot to do, and it is quite cumbersome, if you are not careful, it is a big problem.

For example, the transfer of the vast majority of young and middle-aged people in the entire Northern Song Dynasty at once will definitely have an impact on the grain production of the entire Northern Song Dynasty.

Unlike all other aspects, food is the most important thing in everything, and there are no other products, such as silk, clothes, tools, but in some aspects, it is not very convenient, and there are many substitutes, so it is a big deal not to do this consumption.

If there is no food, what should we do, among the countless disasters, almost all of them are related to food, because of the disaster, the regional output has been reduced, the price of grain has risen, and the peasants who have no foundation and have very low savings have no way to support it.

If people live in this world, they must eat, and if they don't have food to eat, they will die, and no matter how stable the court is, there will be huge chaos.

This is an inevitable contradiction, now the upper echelons of the Northern Song Dynasty did not pay attention, the reason is that the Dinghai Navy has just been established, the population is still small, but in the future, when the population is more than 4 million, the entire Huainan East Road will be affected, in the future, with the railway through, it is more convenient to come and go, almost the entire southeast, or even a little northerly, will venture to the Dinghai, when the time comes, between the Dinghai Navy and the Northern Song Dynasty, there will be a sharp conflict.

Zhao Xin is very aware of this, population conflicts, sometimes, are tragic, in the early days of the industrial revolution in Britain, in order to solve the problem of labor, the enclosure movement was opened, and the matter of sheep eating people appeared at this time.

At present, the development of the navy is no worse than that of Britain at the beginning of the industrial revolution, and the Northern Song Dynasty is far larger than that of Britain, and once this contradiction breaks out, it will be very acute.

Of course, Zhao Xin will not let this happen, after he entered the Dinghai Navy, he has been thinking about this problem and has begun to solve it, but unfortunately it needs to be done step by step.

The development of industry, if you ignore food, ignore the light industry, it is a tree without a cause, just like the Soviet Union in the past, created terrible space technology, the same military power has always made the entire NATO tremble, but in the subtle places, there is no way to guarantee, which is also the fundamental reason for the collapse of the entire Soviet Union.

Powerful military power and the rise of science and technology can promote national pride, but it has little to do with the common people, when the common people can't even afford to eat black bread, any high-end things become so far away.

Food represents population, represents stability, and has been an important issue from the very beginning, although the initial goal is only the total amount of food, and the problem of labor costs has not been considered, and now, it must be considered.

Through Dingjun, the planting technology is upgraded, this planting technology, including seeds and fertilizers, now Dinghai does not have the ability to produce fertilizers on a large scale, but in the future, we can start with small-scale production, and at the same time will develop a large number of island resources.

In the offshore waters, there are many islands, because of the abundance of fish, there are many seabirds, and some islands are even full of guano, unlike other resources, this thing can be directly used as fertilizer.

Guano is a natural compound fertilizer, especially after natural degradation, there are no side effects, as long as fertilization, it can produce results, such guano, the effect is better, even after World War II, or even in the 21st century, guano is still the pillar industry of some ocean island countries.

Fertilizers and seeds, they can only increase the yield, so that the same area of land, produce more food, which has a certain effect on the shortage of labor, can be used with the least amount of land, to feed more people.

This is not what the Dinghai Navy wants to see, so what the Dinghai Navy has been doing is another kind of innovation.

The use of a large number of mechanical accumulation to replace human power, so that under the premise of less labor, can maintain the stability of food production, and then upgrade the industry, incorporate more people, and let these people play a role in industry.

These are all things in the future, and even some things are just starting now, for example, all kinds of advantageous varieties, and constantly cultivated varieties, have played a practical role in the planting of cotton and the northwest.

On the other hand, there are tools, from sowing, ploughing, harvesting, threshing, all aspects, starting from the reduction of labor, as much as possible to reduce the consumption of labor, for the future to lay the foundation.

In the 21st century, that is, the emergence of this kind of thing, so that migrant workers have become the mainstream, and when it comes to the busy agricultural season, the army formed by the combine harvester will even sweep all the way from the north and south of China.

Now, Dinghai does not even have a steam engine, let alone an internal combustion engine, without an internal combustion engine, or rather, without a full-fledged internal combustion engine, this kind of combine harvester is simply not possible.

This does not mean that there is no way for the Dinghai Navy to carry out modifications on the basis of horse-drawn ploughs, for example, to improve efficiency, reduce consumption, and complete the entire cultivation and harvesting work with the least amount of manpower.

In the current Northern Song Dynasty, the labor effect is quite low, the reason is very simple, because the price of iron is quite high, ordinary farmers, it is difficult to obtain good iron farming tools, in the Northern Song Dynasty most of the countryside, are the use of wooden tools.

This is not a joke, these wooden tools, can be wrapped in a layer of iron, is already very lucky, which can greatly enhance the service life of this farm tool, generally speaking, just an ordinary wood, after a part of the treatment, made of farm tools.

Wooden tools, which may have been used in large quantities before the Stone Age, were still used in stone, bronze, and steel, for the simple reason that they were cheap and easy to obtain.

In the countryside, the most worthless is wood, under the premise that there is no large-scale destruction of the environment, many trees, born to grow, nature gives them enough space, so that they can grow wildly, for people in the countryside, even if there is no fuel, they will not buy, but go to the forest, cut some, you can use it as fuel.

Tools made of wood, just a kung fu money, a little serious, will make the whole outline, not serious, almost on the line, these tools, just can be used, the efficiency is really not high, sometimes, a prime labor force spent a day, just ploughed a small amount of land.

Fortunately, in feudal society, for the peasants at the bottom, as long as there are no natural and man-made disasters, as long as there is no forced labor, the pressure on life is not great, even if the labor efficiency is not high, as long as the work that should be done well in the season, it does not matter if the efficiency is low.

Picking chrysanthemums under the east fence, leisurely appear in Nanshan, this can not be all of rural life, that is, most of it, except for the opening of the dynasty, there are few people, most of the time that the dynasty maintains, because of peace, the premise of natural reproduction rate is very high, it may be a few decades, the population can be doubled.

This is acceptable for a natural small-scale peasant economy, but not for the future, provided that the navy occupies labor on a large scale.

At present, Dinghai is working hard in this aspect, gradually solving this problem, and has found some effective methods, first of all, the large-scale popularization of iron tools to improve labor efficiency.
