In that train experiment, Zhao Xin didn't need to say anything, just silently calculated something, after the end, Zhao Xin did not return to Ding Haijun, and then, almost certainly, the railway will attract some attention, and for the railway construction of the entire Northern Song Dynasty, it will also be mentioned to a certain extent.

Sure enough, the situation of the next court meeting was quickly known by Zhao Xin, and in 2 years, not only did Zhao Xin lay a terrible foundation for the Ding Navy, but also made the intelligence network of the Ding Navy spread all over the Northern Song Dynasty.

What is easier than money to open the way, Zhao Xin himself did not cultivate too many spies, but in the various chambers of commerce throughout the Northern Song Dynasty, as well as some people who were bought because of this, Zhao Xin already knew most of the things in the Northern Song Dynasty, let alone the court.

The Privy Council intervened in the battle for the railway, and Zhao Xin had long expected that the railway was a dual-use thing, and it played a great role in the military in the era of war.

The development of things did not exceed his expectations, Ye Qingchen relied on his in-depth understanding of the railway, and finally won the jurisdiction of the railway, and the next step was definitely to discuss the construction of the railway.

Sure enough, without waiting for a few days, Ye Qingchen came to the door, and his preparations were relatively complete, proposing that the Third Division invest 3 million yuan and Ding Haijun invest 12 million yuan to jointly build the next few railways.

Zhao Xin took a brief look, and as he expected, they were the railways leading to the Daimyo's Mansion, Henan Mansion, and Jiangning, which were not single-track railways, all double-track railways, and similarly, at the same time as the construction, the double-track from Bianliang to Yingtianfu would also be built.

These three places, in addition to Jiangning, the other two are one of the four capitals, the strategic position is very important, and Jiangning, along with the development of Jiangnan, the important role of food, as well as a variety of developed economies, has also become the focus of inevitable development.

These railways are not unimportant, whether it is the status of the city or the economy, building them will inevitably get enough profits, but now it is not necessary.

Zhao Xin did not directly veto Ye Qingchen's request, these three railways will definitely be repaired in the future, but there is no need to repair them now, because of the limited funds and personnel, even if the Ding Navy expands at present, it can only have the ability to build a railway of more than 2,000 miles.

The distance between Bianliang to Henan Mansion and Daimyo's Mansion is not long, about four or five hundred miles, and it is a little far to Jiangning, at least 1,200 miles.

The three railways combined, almost a little more than 2,000, for the double line, 12 million is a bit reluctant, but as long as you save a little, there is a future, and a little subsidy from the state capital, it is enough.

The total length is more than 2,000 li, that is, almost with reference to the production capacity of the Ding Navy, that is, if these three railways are built, there will be no ability to build other railways, and relatively speaking, which railway is more important.

Zhao Xin handed over the plan that had been prepared to Ye Qingchen, Ye Qingchen changed for a moment, and then opened the plan.

Like the previous plans, this plan is really biased towards actual data, and there are many things listed in detail, and the ultimate goal is to the northwest.

A railway connecting Xiping Province and Bianliang Province in the northwest, passing through Henan Province and Jingzhao Province in the middle, and finally arriving at Xiping Province.

With a total length of more than 2,000 kilometers, it crossed Henan Province, passed through Guanzhong, and then exited the customs in the northwest to reach Xiping Mansion, which Han Qi took from Western Xia.

If it was 2 years ago, when the Western Xia had not been completely resolved, and Ye Qingchen had to have a headache for the northwest, he would definitely not hesitate to invest in such a railway.

A railroad that is more efficient than a canal would be of great help in effectively solving the problems of the Northwest.

Now, the timing is different, the Western Xia has perished, and after the Liao State occupied the Western Xia, it seems that the strength has increased greatly, but in fact, the Western Xia occupied by the Liao State is decreasing the threat to the Northern Song Dynasty.

The appearance of the fortress and the longbow also made the combat effectiveness of the border army increase significantly, and the number of border armies was decreasing, and the forbidden army returned from the northwest one after another, and some archers and banners were also disbanded to maintain a relatively low army.

At present, the total number of troops in the entire northwest is about 400,000, which is more than the rest of the Northern Song Dynasty, but compared to before, it is close to one million, and it has been withdrawn too much.

Similarly, Han Qi's excavation project in the northwest, after a year of fermentation, has begun to show its power, a season of summer grain, has changed the history of the lack of grain in the northwest, at this time, to do such a railway, isn't it a waste?

Zhao Xin will not put forward it casually, such a plan, which is easy to be criticized, according to Ding Haijun's writing method, there will be a series of explanations later.

Sure enough, from the second page, it is the whole part of the explanation, first of all, the military one.

How important is the northwest, the role of a railway in the military, Ye Qingchen knows very well, if the entire army can advance in an expedited way of 800 miles or even 600 miles, I don't know how much money and food will be saved, and the reinforcements will be endless, even if it is to send hundreds of thousands of troops.

Western Xia has perished, is it necessary to do this, although the Liao State should also be guarded, but the Liao State did not send troops from Hebei, but from the northwest, it was in the hands of the Northern Song Dynasty, which is also the reason why the Western Xia has always been harassed, but has not attracted attention.

Even if Western Xia wins, it is just to harass the northwest, even Jingzhao, he can't reach it, but the Liao State is a threat, once it breaks through the three levels, it will face Hebei, once it breaks through Hebei, it will be the old thing of the Yuanyuan Alliance.

The use of the military, even if it is written in the flowers, will not make Ye Qingchen pay more attention to it, he pays more attention to the back, and sure enough, he found the role of the economy later.

In the middle, it is mainly divided into three parts, the Northwest Water Conservancy Project, which has entered its second year, continues to expand on the original foundation.

In the past, it was the construction of the main river basin, mainly using the water of the Yellow River and other waters, to irrigate the land.

This has already shown its effect, and the northwest has opened up countless lands and harvested a large amount of grain, which has become the foundation of the northwest.

To continue to deepen is to continue to do subtle work on the basis of the original foundation, so that there is enough water and more fields.

It is expected that by the end of this year, the area of cultivated land will increase by three times on the existing basis.

3 times! This number frightened Ye Qingchen, Ye Qingchen knew that the total amount of land in the Northwest at present, in terms of the Northwest alone, or a certain place, this is not a very big number, but when measured to the extent of the entire Northwest and even the Northern Song Dynasty, this is already very large.

The cultivated land in the northwest can even reach the level of Henan, but now, what is the concept of 3 times the result, Henan and Guanzhong, plus part of Hebei in the north, are only so much.

There is only a lot of population in the northwest, even if Han Qi used various means to increase the population of the northwest, their population is only one-fifth of that of Henan, so much food, enough to support the army in the northwest, and at the same time radiate outward.

After 3 times, it will be more, and if it is calculated, 3 times, 20 million mu of land will be developed, and 40 million stones of grain can be produced according to 2 stones.

This grain is very terrifying, according to the calculation of 4 stone of grain per person a year, these grains alone are enough to feed 10 million people.

In other words, this place has become a granary, even Ye Qingchen did not expect this, he thought that the northwest could support the cost of hundreds of thousands of troops, and then support the entire border area, but he did not expect that he could even radiate the entire Guanzhong and Hebei, and even the consumption of a part of Bianliang could also be taken into account.

Tokyo has a population of one million, and therefore, food is a huge problem, and every year, the grain transported from Jiangnan is as high as millions of koku, and if this grain is transported from the northwest, it seems that it is also a good choice.

However, a subsequent data once again made Ye Qingchen's eyes twitch, and among the estimated output, it was not 40 million stones, but 90 million stones. That is, the yield of these lands is up to 4.5 stones.

Although Ye Qingchen was born as a scholar, he has been involved in physical objects for many years, which makes him not a person who doesn't understand anything.

To put it bluntly, the three divisions were in charge of the finances of the entire Northern Song Dynasty, some of which were a combination of the Ministry of Finance, the Food Bureau, the Taxation Bureau, and the Planning Commission.

How much is the tax paid in the Northern Song Dynasty every year, and what kind of land is owned for the output of 4 stones, even in the south of the Yangtze River, there are only a few lands with such an output.

Ye Qingchen asked Zhao Xin a question, and Zhao Xin also answered it simply.

The reason for such a high yield is that the support of Ding Navy's agricultural technology is indispensable.

Compared with the farmland and land conditions of the entire Northern Song Dynasty, the land in the Hetao Basin may have such and such problems, but one thing is worth affirming, that is, the land area is large enough, and it also has a large amount of animal power.

Zhao Xin knew that in ancient times, there was once an eight-ox plough, which could concentrate eight oxen to plough the land, but that kind of plough was very restrictive and could not be used by ordinary people.

On the basis of the combine harvester of later generations, with reference to the use of livestock, Zhao Xin made 16 oxen plow, which can be used by 16 oxen side by side, and can cultivate a considerable area at one time, with extremely high efficiency.

This study happened to be used in the northwest, there is not much else in the northwest, that is, there is a lot of land, it used to be the land of Western Xia, there is no use of a small part, on the basis of the village, it is assumed that a large-scale construction farm, a farm has 10,000 acres, or even more land.

Under the premise that there are few people in the land, these large ox plows can come in handy here, which is also the fundamental reason why Han Qi used one-fifth of the population and cultivated more land than in the Central Plains.

The eight-cow plough is suitable for improving efficiency, but it is not enough to increase the yield per mu, what really improves the yield per mu is the agricultural technology of Ding Haijun, whether it is seeds, as well as the cultivation technology of cultivation, which has been helped by Ding Haijun, Han Qi has copied and used it, and the effect is good.

These technologies, the improvement is not high, is the icing on the cake, but what is really effective and shows its power is fertilizer.

Crops and flowers, all rely on dung to make a house, hard-working Chinese, long known the role of dung, and even the Tang Dynasty had a person who made a fortune because of this.

But this kind of thing, in different places, is different, because of the smell, no one wants to study it.

This point, and later generations are completely different, Zhao Xin knows the role of farm fertilizer, but also knows some fermentation and mixing skills, in agriculture used early, especially in the northwest, because there is no foundation, a blank paper, easy to calligraphy and painting, at the same time, although there are not many people, but the number of livestock is huge, the concentrated treatment of livestock manure can not only reduce pests and diseases, but also increase production.

These effects are combined, that is, the current high-yield, highest-yielding farmland in the northwest, winter wheat plus summer grain, harvest more than 9 stone, even the worst, two seasons, more than 3 stone, far more than the thin fields in the Central Plains.

After Ye Qingchen understood it thoroughly, he also asked Zhao Xin about the relationship between fertilizers, and knew that it was the manure of the livestock and was slightly disappointed, but then, Zhao Xin's words made him excited again.

Zhao Xin next, will cooperate with the three divisions, in the vast majority of the Central Plains population of more than 20,000 cities, the construction of a manure dump, although this thing smells, but it is a treasure, the manure in the city is cross-flowing, and it is not suitable for the city, appropriate manure, and then sell, can increase the output of grain on a large scale.

However, in the northwest, there are a large number of livestock and a large yield, which is enough to ensure that most of the land is fertilized, but in the Central Plains, although the population is large, the countryside cannot collect it, and the cities alone cannot supply so much.

Some can be improved, according to the data given by Zhao Xin, it may be possible that after the construction of this, the entire north can increase the output by about 30 million stones, and the average yield per mu can be increased by about 4 catties, which is very inconspicuous, but it is very critical to the stability of the dynasty.

A total amount of grain is enough to tilt Ye Qingchen, it is customary to be barren in the north, in Bianliang, there is also a Beijing-Hangzhou Grand Canal, after passing Luoyang, the freight has increased significantly, and Guanzhong, which was once the country of abundance, has become sparsely populated.

If there is enough food for Guanzhong to recover, the support for the entire Northern Song Dynasty, as well as the support for the Northwest, is very large, and this alone will be enough to build a railway.

Not to mention animal husbandry and mineral deposits, the advantages of animal husbandry in the northwest itself, after the northwest border problem is solved, it will be highlighted, coupled with Zhao Xin's technology, semi-captive breeding, green storage feed, these can make the same grassland, feed more cattle and sheep, the cattle and sheep in the northwest have skyrocketed on the original basis, and can give more meat to the Central Plains.

Not to mention the various mineral deposits in the north, coal, iron ore, and other minerals that have not been heard of, as long as they continue to be developed, the benefits will be even greater than those of other roads.

Three key points, very clear and intuitive, Ye Qingchen didn't care about the previous railway lines, how many powerful people were behind it, and directly made a decision, and decided on the construction of such a Dongping Railway, Tokyo to Xiping Mansion, a railway with a total length of about 2,200 miles, and it was decided.
