The two of them thought of going together and did the same thing, both using the water of the Yellow River, which is the most important river in the whole north, with a much higher flow than other rivers, and at the same time, the relationship between the higher terrain and the easy diversion of water.

The water volume of the Yellow River is huge, and it can also rank among the top in the world, and the surface runoff of the entire Yellow River flow through the area will gradually be injected into the Yellow River, and then flow into the sea, up to tens of billions of cubic meters per year.

If the water of the Yellow River is introduced step by step into the canals, the utilization rate of the water of the Yellow River can be increased to 10 times or even 20 times the previous level.

From dry land to irrigated land, from relying on the weather to rely on water to eat, the latter is more reliable, and at the same time, farmland water conservancy construction is still a systematic project, which has a huge role in flood disasters.

In feudal society, the three most damaging to agriculture were floods, locusts, and droughts.

What is a flood disaster, it is a large-scale concentration of precipitation, causing the water content in the soil to rise, exceeding the limit of the soil and plants can bear, in this case, if the water is not drained in time, the food crops will rot in the land, resulting in a bad harvest.

Needless to say, drought is not rainy, there is no water, as for the locust plague, which is closely related to the drought, there are locusts after the drought, the main reason is that locusts survive in a warm and dry environment, if it rains, or the climate is too humid, most of the locust eggs will not be able to hatch.

In the case of severe drought, it is simply a breeding ground for the natural growth of locust eggs.

Even in the season of great drought, the Yellow River, which stretches for five or six thousand kilometers throughout northern China, also has enough water, and the drought does not have much impact on a large river like the Yellow River.

When the ravines spread over the Yellow River bring the water of the Yellow River to the arid land, even a drop of rain can ensure the growth of crops.

In the 21st century, it has emerged that in desert areas, the bottom irrigation planting method can not only greatly reduce water waste, but also the transpiration in desert areas, the effect produced is not comparable to a large dry weather.

Needless to say, floods, unless it is a once-in-a-century flood, otherwise, the systematic water conservancy project, for the flood prevention effect is considerable, under the premise of large-scale precipitation, through ravines and lakes, under the diversion, it will not be worse than the original.

There is no perfect solution to the locust plague, but the hatching rate of locusts in the watered ground will be greatly reduced, which also reduces the effect of the locust plague from one side.

This effect, until later, Zhao Xin clearly described the causes of the three disastrous weather, they understood, became rich Northern Song Dynasty, began to invest huge efforts, in the construction of farmland water conservancy, almost occupied an important position in the appropriation, and the dense network of ravines also spread throughout the north, after that, under the influence of the climate of the Xiaoice River, the impact of the Northern Song Dynasty was minimized.

Pastures do not need water, but relatively little, the average annual precipitation of the general grassland, the average annual precipitation is less than 400 mm, or even lower, in this sense, the water demand of the grassland is far lower than that of grain, but if the water and grass are really abundant, there is no water.

Only the peculiar landscape that can be shown on the grassland, long-term drought, even the grass does not grow vigorously, but a heavy rain only, overnight, the grass can grow more than ten or twenty centimeters, and give birth to a lot of things that are not originally there, for example, all kinds of fungi, wild onions and a large number of wild vegetables.

At this time, if there are aerial photography tools, it can be clearly seen that more than half of the land in Lingzhou, all areas no more than 150 miles away from the river are planned as large-scale farming areas, and a small number of them are used as pastures.

Now, for the sake of the entire complete construction, most of Lingzhou is shrouded, and the huge livestock obtained from the Lingzhou Peace Conference, which is said to be the income of the peace agreement, will be handed over to the center, but it can even be sold and used as funds for the construction of Lingzhou, and some animals can be used for the construction of Lingzhou, which is even more so.

Simple animals, there is no way to have an effect at all, the key is actually people, there are huge manpower captives in Western Xia, these themselves are people who grew up on horseback, they are born to serve animals.

These herdsmen and these laborers from the Northern Song Dynasty have made it possible for all this, and now, the weakest link, a large amount of capital investment, there is no problem, from the cattle and horse conference, at least 18 million yuan or more of the funds, this money, even if it is placed in the entire Northern Song Dynasty, it is also a very terrible fund, and if it is placed in Lingzhou, it can definitely be called terrible.

Even the large-scale farmland water conservancy projects throughout the north have been greatly expanded because of the obstruction of the old forces in those places, and the final total investment may be as high as 25 million yuan, but the northern part of the Northern Song Dynasty is much larger than Lingzhou and even the four roads in the northwest.

However, Lingzhou and Northwest Fourth Road can get at least 18 million, and even later, with the upsurge of cattle and horse business, this money may increase at any time, which is very terrifying.

Money is not everything, but under the premise of money, coupled with power, at least 250,000 manpower, about 50,000 head of livestock, more than 30,000 vehicles of various kinds, and all kinds of excellent metal tools, this unprecedented project will be completely completed and change the face of the entire Lingzhou.

In the winter, on this piece of land in Lingzhou, 7,500 miles of diversion canals will be built, in the future, when the project spreads throughout the northwest, the number of canals will increase to 25,000 miles, and at the same time dig a large number of reservoirs, dig a huge reservoir that can hold more than 250,000 square meters of water, once the project is finally completed, the entire Lingzhou, the area of irrigated land, will increase by more than 5 million acres,

As long as there is enough manpower and animal power to plant these fertile fields, as long as it takes more than half a year, Lingzhou can completely solve the problem of grain, which is not an extravagant hope, but a combination of theory and reality.

At a time when this large-scale project that completely changed the entire western part of China was in full swing, Han Qi returned to Lingzhou.

In the month he has been in Weizhou, Han Qi has never let go of the monitoring of Lingzhou, many large-scale projects, and even go to Weizhou to consult Han Qi's opinion, but it is hundreds of miles away, it is a little difficult to control it directly, at most it is indirect, and he can't wait to know what Lingzhou is like at present.

At a distance of 600 miles, under all the cavalry, Han Qi spent a total of three days, and he even only brought back two battalions of elite cavalry, and the rest guarded the materials collected from Weizhou, advancing slowly.

Although it is said that larger quantities of materials need to be collected by the money village and the chamber of commerce, and then sent to Lingzhou one after another, but before this, they were also in Weizhou, and used funds to transfer a part of the materials, which may only be 1 million, but it will greatly stimulate the entire Lingzhou project.

To be honest, before the opening of the Weizhou Conference, Han Qi never thought that at the Weizhou Conference, he could harvest so much, and the price of cattle and horses was very high.

After all, in Han Qi's view, in the past, the financial income of the entire Northern Song Dynasty was only twenty or thirty million, and they relied on an auction to do so much.

But his personal experience in the Daimyo's Mansion made Han Qi understand that the entire Northern Song Dynasty was not without money, but that the money was in the people, an auction, how many things were auctioned in the end, tens of millions, as long as there were valuable products, they could create suitable profits, when one or two people had limited funds, but when the entire Chinese Chamber of Commerce was gathered, this money was very terrible.

The cattle and horse business is much more attractive to the north than to the south, and there is more water in the south, and the cattle in the north are not adapted to the land in the south, so they are all big businessmen in the north.

It was only after arriving in Weizhou that Han Qi found that he had underestimated the capital of these big businessmen, thinking that he would be able to sell a few million at most, and 5 million had already given him a basic number, but in the end it reached 15 million, and it was very likely to climb to 20 million.

Even if it is in Han Qi's status, he will be amazed by this money, which was in the first two years, but the entire financial income of the Northern Song Dynasty is now invested in the barren Lingzhou without hesitation, if it were not for more than 20 million livestock to lay the foundation, he would never dare to do this.

However, now, what he can bring is about 3 million materials, cash or something, and bring over the 500,000 yuan in cash from the Weizhou transaction.

This money, copper money is very little, most of it is gold and silver, 500,000 yuan in cash, up to 8 million catties, if you carry hundreds of miles, this cost is too great, but gold and silver are much better, gold is only 5,000 catties, even if it is silver, it is only 50,000 catties.

Although gold and silver are rarely circulated in ordinary places, they can be easily exchanged for copper coins in various places, which is the best choice for Han Qi, who is preparing to reward the three armies.

When soldiers eat food, the war that has been won, always have to reward the three armies, before it was only in the material, for example, in the capture of Lingzhou, as well as beef and mutton compensation, the rest is the book, but also need to use realistic things, to give a booster.

In the twilight of the night, Han Qi arrived at Xiping Mansion in Lingzhou, and then for a whole night, he looked at all the things in the entire Lingzhou in the past month, maybe there are not very satisfactory places, there are very few of these places, most of them are in accordance with the regular steps, slowly developing.

Han Qi knew it in his heart, and began to solve some of the previous things, by the way, a series of regulations were all over the place, and the next day, it detonated the upsurge of the entire Lingzhou military and civilians
