After the above things have been tested in detail, another characteristic of Lingquan water is reflected, for example, after planting alfalfa grass in the field, after ploughing the land, replanting wheat, normally speaking, there will be some alfalfa roots in the ground that have not been cleared, and a small part of alfalfa grass will inevitably grow in the second year.

But the land that has been watered with the spiritual spring water does not, and it can almost even be said that there are no weeds, and the only place where weeds grow is at the location of the ridge.

For the Ministry of Agriculture and others, they all think that this is a miracle, including all the Han people, but Huo Gang knows his own things, and Huo Gang pondered, it is very likely that the spiritual spring water catalyzed the wheat in the field, and when the wheat is growing, because this field is a single wheat, the number of wheat is the largest, so it is possible that these weeds mixed with the wheat have all absorbed their nutrients and killed them when they were developing.

Of course, this is Huo Gang's idea, but the real situation, it is estimated that there is a gap with this, because normally speaking, Lingquan water strengthens the activity of wheat, and also strengthens the activity of alfalfa.

Anyway, Huo Gang didn't know, if the science and technology of this spiritual spring water reached the level of science and technology of later generations, it might be possible to conduct further self-study analysis of it, but at present, it is unlikely.

Anyway, this is a good thing, there are not too many weeds, which means that the people hardly need to weed, so that the physical work of cultivating the land will be reduced, and then the area of arable land will increase.

And the last excellent thing is that most of the cultivated land in the Dahan River Basin almost does not need to be watered, because the spirit of Yumen is passive and can always rain at the right time, so that most of the time the land does not need to be cultivated.

And because of the flow of spiritual spring water, the impact of spiritual spring water on the land on both sides of the river is imperceptible.

Of course, if you directly irrigate the spiritual spring water, you can actually increase part of the yield, at least it has a great advantage in the optimization of wheat seeds.

However, these tasks are left to the government, and the Ministry of Agriculture has set up a special breeding department, and most of the Han people are now accustomed to buying seeds directly from the Ministry of Agriculture, because the grain produced is more productive.

In fact, it is okay for them to keep their own seeds, and the yield is only slightly lower, but for the people, they are not willing to let an acre of land be dozens or even a hundred catties lower.

Therefore, in fact, the land area planted by the farmers in Dahan is quite large, but each family actually has spare power, and this time after the migration of some people, I believe that the remaining people here can still cultivate these fields.

You must know that the area of cultivation was not expanded before, not because the people did not want to plant, but because of official control.

And this time, the matter of immigration is related to all the strategic situations of the Han Dynasty in the future, so Huo Gang must make it clear to the people, because he now has a very high influence on the people of the Han Dynasty.

In addition to agriculture, we have to talk about animal husbandry here, the total number of sheep in Dahan is about 15 million according to official statistics, which seems to be small, but in fact, the sheep slaughtered every year are not counted in the people's own homes, and the current major cities in Dahan alone consume nearly one million sheep every year.

This is just sheep, not everyday chickens, ducks, pigs, etc.

After five years, the herd has increased the number of cattle to more than 3 million, which has allowed beef, milk, and dairy products to enter the lives of the people, as well as consumption in the city.

However, at present, beef is still the most expensive, mainly because the reproductive rate of cattle can not be compared with sheep and pigs, although the growth period of pigs is relatively long, but pigs are more one-time births, and although the sheep are less, but the growth period is short, so the number of reproduction of the two is increasing very fast.

And almost all of these animal husbandry were raised under the feeding of alfalfa, so the consumption of the grassland of the Han Dynasty was relatively small, such as the waters of non-spiritual spring water, such as the middle of Yiwu City to Yumen Pass, which could originally be said to be grassland, or desert.

There is a little grass, but not much, it is estimated that several square kilometers to herd sheep, that is, to feed one or two hundred sheep, but in recent years, because of the wind and rain of the spirit of Yumen, the precipitation of these grasslands has been increasing, and these precipitation increases also means that the grass on the grassland grows more lushly.

In addition, there is no sheep and other grazing, and over the years, the original desert has gradually begun to become green, and it is a bit like the Inner Mongolia grassland in later generations. It is estimated that if this continues, perhaps many years later, there will be scenes of cattle and sheep in these grasslands blown by the wind and grassland.

And this kind of soil and water conservation is obviously gradually benign, to be honest, Huo Gang is now a little worried about the impact on Datang.

Not only that, but places such as the Pamir Plateau in Central Asia have far more soil and water conservation than later generations, and the most important of them is the Tarim Basin.

The Tarim River basin almost surrounds the mountains around the Tarim Basin, and there is still a river across the middle Tarim Desert, after the spiritual spring water, the flow of the Tarim River began to increase, and the two sides of the river quickly turned into fertile land, and a large amount of alfalfa grass was directly put on both sides of these banks, regardless of whether it was inhabited or not.

The Tarim River is a very large river, it is 2,179 kilometers long, and it is composed of seven or eight major rivers, a total of more than 140 rivers of all sizes converge from the peaks around the Tarim Basin, and the entire basin covers an area of nearly one million square kilometers.

However, the total number of people living here in this million ordinary kilometers is two or three hundred thousand, and although the Han Dynasty later immigrated, there is still a large area of no man's land.

And all these no-man's land big men let the cavalry troops carry a large number of alfalfa grass seeds to sprinkle in every corner of the entire Tarim River Valley, and this process alone lasted for nearly three or four years.

Of course, it is not possible to sprinkle all over the area, just sprinkle a part of it every area and let it reproduce on its own, and now alfalfa has spread to all corners of the Tarim River basin. Except for the land that has been reclaimed as fertile land, the rest is completely savage growth.

And because after turning into spiritual spring water, the whole basin is full of vitality not only alfalfa grass, but also trees on both sides, those tenacious weeds, etc., all began to expand in all directions, which led to the continuous increase of oases on both sides of the Tarim River.

The Taklamakan Desert, the largest in the Tarim Basin, has been shrinking in recent years, although the rate of shrinkage is too slow compared to the entire desert, but this must be a good thing, isn't it? Deserts like this, you want to shrink them...... It was simply too hard, only the power of nature.

Moreover, Huo Gang believed that as the Spirit of the Jade Gate continued to strengthen the surroundings, when there were more and more vegetation around it, and the precipitation in the desert began to increase, perhaps after more than a thousand years, only a small part of the remaining area of the desert would be left.

The reason why Huo Gang said that he was afraid of having an impact on the Tang Dynasty was that if the precipitation in the current territory of the Han Dynasty increased, and the two rivers of the Yellow River and the Yangtze River, which originate from nearby glaciers, it is estimated that the water flow will increase, and perhaps the Yellow River downstream will change course.

However, it depends on how Li Shimin controls it, if the Tang Dynasty also pays attention to it now, and does not reclaim fertile land indiscriminately, the Yellow River should not be rerouted indiscriminately at present.

"Natsutake." After explaining this, Huo Gang turned to Xia Zhu's side again.

"Chief."

"In addition to the current Minzhou, the immigrants from several cities such as Bard City on the side of Hezhou will be handed over to you, and there will definitely be no majority of the people in this part to migrate for the time being, so the migration policy will be transferred to these merchants."

"Tell all the commercial banks, all those who are willing to do business in these cities, will be given part of the tax exemption policy, as well as related preferential treatment, in this regard, your Ministry of Commerce will discuss, in addition, if these are willing to follow the commercial banks to migrate to these cities to live, the Han government can provide these workers with housing loans free of interest, which will be subsidized by the Dahan Central Bank."

"In addition, some commercial banks of state-owned commercial banks will also start recruiting workers in nearby Bad City, and the Ministry of Industry has also followed suit, and those who are willing to follow the commercial banks to work there will increase their wages and related benefits." Huo Gang said directly.

"You must do a good job in the relevant welfare, after doing a good job to say hello to the Propaganda Department, and then directly focus on publicity, the Ministry of Industry, Yang Wu, you will first build a cement plant and a steel plant over there, and the materials will be gradually transported from Yaochi City, remember one thing, even if you let the workers transport things together, don't be afraid of wasting money, the funds of the treasury can be subsidized."

"Yes!" Yang Wu and the others immediately nodded their heads one after another.

For Dahan, it is not a problem at all to give some financial subsidies to his own people, and the money is in the hands of the people, and it is used to improve the living standards of the people, and there is no problem at all.

Because the trade of the Han Dynasty to all the surrounding countries is a trade surplus, and this trade surplus brings huge profits, the Han treasury is very sufficient, and the performance of this profit is that the wages of the people have begun to gradually increase.

And this increase in private wages is almost always the work of private commercial banks, which means that this is the self-regulation of the market, not the intervention of the Han government.
