Meng Xiang didn't know that he had begun to focus on investing in the lottery ship, and he was concerned about two things at this time, both of which were domestic.

As for the European side, now that the fire has been lit, all that remains is to wait and see. Only by training one's own internal skills and laying a good foundation can one be invincible in the future era of war.

At any time, there is no panic when there is food in hand.

According to preliminary statistics, there are nearly 300 million mu of cultivated land controlled by the vanguard army, but the vast majority of them are medium- and low-yielding fields, and the production of one mu of land does not exceed 150 catties. Although some of them have been renovated through the construction of water conservancy, the output is still not high.

As Meng Xiang later knows, if you want to have a high crop yield, in addition to the artificial careful monitoring of the material and climate change, you generally pay attention to three points, seeds, water and fertilizer.

With the problem of seeds, Meng Xiang did not dare to adjust the use of those new varieties on a large scale for the time being, and it was too late to cry once there was an accident. As for the use of coating ultraviolet irradiation and other technologies, the specific situation has not yet been figured out at this time, and the seeds can only be selected from those produced. As long as the seeds are chosen, it is also guaranteed that when other conditions do not change much, a good yield can be obtained.

The problem of water, as soon as the New Year passed, it encountered a large-scale spring drought.

Thankfully, a busy winter of repairs to water facilities has been able to bring water to the farmland around the rivers and ditches.

But in this era, many places are far away from the river, and they can only rely on the sky for food. The cost of drilling wells is high, and it is cumbersome to escalate. Even drinking water for food is a hassle, let alone growing crops.

However, with the base, it seems that all of a sudden it has become no problem.

In order to save resources in the future, Meng Xiang only meets the coal needs of the power plant, and generally does not expand production. Since the opening of the Middle East oil base, there has been much less mineral exploitation in the country, and the number of mining vehicles produced has also decreased a lot. But because of an accident, Meng Xiang found that he still neglected the use of mining vehicles.

The Mining Cart's ability to explore very deep, but its mining depth is not. The first level is only 100 meters in maximum and the second level can reach 300 meters. But this one is a vertical lift. The mining cart cuts a large hole directly from the top to draw minerals. After mining, the ground was left with nothing more than a deep hole that was backfilled. But Meng Xiang just ignored the function of this burrowing.

If it weren't for the matter of digging a well and drinking water, Meng Xiang suddenly thought of this deep hole, he might have to ignore it for a long time.

Water is also a resource.

Mining vehicles also explore water resources and can be directly located in the most suitable places to draw water. At this time, the groundwater is not so polluted, except for some surface groundwater that is not suitable for drinking and requires deep wells, most places do not need to dig too deep.

Meng Xiang knew that even if it would cost a lot of money to open a 100-meter-deep well in later generations, now the mining truck could easily do it. In this way, Meng Xiang has another function in his hands.

As long as the water problem is solved, many places can be developed and survived. In later generations, whether it was the Loess Plateau or the Northwest Regions, in fact, there was not a shortage of water, but the water was underground, and the cost of human use was too high. The mining vehicle can directly drill wells to solve the problem of water resource utilization.

The diameter of the opening of the first-class mining vehicle shall not exceed 1 meter, and the second-level shall not exceed 2 meters. But that's enough.

Meng Xiang even thought about the use of oil wells. The oil well is exploited at a greater depth, and it is not necessary to drill wells, but the pipeline that comes with the oil well can be used by Mengxiang. The pipeline of the oil well can provide the diameter length of the direct jurisdiction, that is, the secondary oil well can directly extend the 200 km long 300 mm diameter oil pipeline. The 200-kilometer-long oil pipeline can be used as a water pipe.

In many places, the water shortage is relatively severe, and the water pipeline can directly transfer water on a large scale, and Meng Xiang can directly move the oil well to the lake area, draw lake water, and transport it to a place 100 kilometers away. And the pipeline is not just 200 kilometers, find a place to break it, you can repair it, but this practice is a bit too extravagant. At present, there is an urgent need for many pipelines in industry and in the city, and the quantity is limited to supply there first. Civilian water can basically be solved by drilling wells. There are only a few mountainous areas that are not suitable for drilling wells and have difficulty in drafting. But Meng Xiang didn't plan to consume more resources there.

Social resources are a certain amount in a certain period of time, and if too many resources are spent to show a person's winning project, it is not necessary at all.

Those places with particularly harsh environments should not be places where people are going to live in the first place. It is only because of the war and other reasons that people live in seclusion. But with that comes a series of problems, not just about water, but also about transportation, communications, education, and even food. If the number of people living in groups is okay, the place with a small number of people continues to live in an ancient way all year round. But there are many such villages, and even in later generations, such mountain villages with less than 100 people can be seen everywhere.

Some people who have a pain in the egg find it comfortable that way, but let him stay for the rest of his life, he will definitely go crazy. As soon as the night falls, the breath of the desolation that is pitch black in all directions can directly lead to the loneliness in the depths of the human spirit.

Human beings live in groups, and it is only by collective strength that they defeat other creatures and become the overlord of the earth. Too few of them are not conducive to the development of mankind at all, and if you don't think about yourself, you also need to think about future generations, and the lack of education and communication will only create generations of ignorant people.

The depths of the mountains were supposed to be the preserve of other creatures, suitable for short-term stays, but not for long-term habitation.

From the perspective of environmental protection and biodiversity, from the education and future of those mountain people, and from the perspective of resource conservation, Meng Xiang has begun to implement the plan of merging small villages into large villages, or even merging villages into towns.

The relocation places are not very far, and basically a large village and small town are planned in a nearby place with better conditions. In order to get it in one step, the planning is mainly based on small towns. In this way, it can lay a good foundation for the next step of water supply and power supply, and the road and telephone.

The surrounding land is planned for new integration, and arrangements are made for the cultivation of food or cash crops.

Of course, this policy is long-term, and it needs a little bit of influence change, a little bit of resettlement, and to avoid forced demolitions and other behaviors. In fact, the buildings of those mountain villages in this era are just a little stone houses and thatched houses. And the blueprint of the town promoted by the vanguard army is tempting. Coupled with the temptation of subsistence allowance and the compulsion of compulsory education, except for some elderly people who are nostalgic for their homeland, such measures are still very popular, after all, the outside world is more exciting and attracts people's attention.

It is with this kind of planning that when digging wells, those that are too remote and in poor conditions are excluded, and the rest is to persuade the people there to come out. Those mountains are closed for forestation, giving those creatures that are almost extinct under the pressure of human beings a little free space, and can also ensure that more biological resources can be used for people in the future.

In this way, the number and difficulty of drilling wells have been reduced a lot, and with the super mining speed of mining vehicles, not only the problem of drinking water for people has been solved, but also the watering of cultivated land has been partially solved.

By the time of spring ploughing, most of the dry land that depends on the weather for food can be watered. In addition to well water, there is also river water. In many places, although the dryland is not far from the river, the height of the dryland restricts the irrigation of the dryland. With the help of the base, all this is not a problem. The engines on the various vehicles, tanks, and even airplanes produced at the base gave more impetus to this era.

The power of the engine can quickly pump water from ditches and rivers to higher and farther places.

In this era dominated by manpower, things like engines are far away from ordinary people, even in a county, there may not be a few. But the base can be dismantled and repaired by repair shops, which are provided by thousands. If it weren't for the shortage of oil, this tens of thousands, or even more, would do.

Even though the North China Oilfield has been exploited, it has consumed more places, and the North China Oilfield has only a dozen or so oil wells erected there, and has not formed an energy base to expand production.

Imports of oil continued, and neither the British, Americans, nor the Germans could afford to transport oil here for the Avant-garde. So Meng Xiang is still transporting through the cows. The submarines of the vanguard army can attack their own transportation routes, and in the same way, their patrol forces can easily determine the transportation routes of the vanguard army. Only submarines are still the safest. However, it is also difficult to train submariners, and they have to participate in submarine battles, so the number of cows is still small.

At this time, the area near the Zhongyuan oil field was no longer a front-line war zone, and Meng Xiang had already begun to prepare for the start of mining. Although we are in line with the principle of using foreign resources first, we urgently need to complete the initial accumulation at this time, and we will talk about it first.

So the number of corresponding engines can also be increased a lot. It's just that the number of people who know these machines is too small, and the scarcity of people who can do it makes the use of engines still not popular.

In order not to delay watering during the busy farming season, even those relevant technicians in the vanguard army went to a nearby place to help when they were not busy.

In addition to diesel and gasoline engines, there are also electric motors, and with the power supply of the base power plant, as long as the line is pulled, the normal operation of the motor can be guaranteed.

At this time, more than 2,000 engines were mobilized to ensure agricultural watering. With the engine, the water pump is also easy to solve. Various base parts, plus imported equipment parts, assembled more than 2,000 water pumps. Although there are not many counties and cities that are distributed in various counties and cities, with the addition of shoulders and hands, and all kinds of utensils are on board, at least it can ensure the water supply of cultivated land and alleviate the spring drought.

This time the spring drought had a little impact, but it could be compensated for in other ways.

At this time, the grain output was calculated in terms of wheat, and the average yield per mu was only more than 100 catties, and some places were still planted in a single season. In later generations, those who took care of the crops were definitely not as careful as the people at this time, but they could still achieve a high yield of 100 catties. In addition to the improvement of seeds, the most important reason for the high yield per mu in later generations is the use of chemical fertilizers.

Since last year, Meng Xiang has asked people from the College of Agriculture and Forestry to test the role of fertilizers. Even if there is no 100-mu experimental field with improved seeds, the yield per mu can reach five or six hundred catties.

That's a threefold difference.

At this time, the total amount of grain itself did not have much surplus wealth, which is why there was always the phenomenon of starvation to death, and some rich peasant landlords did not have much surplus grain in their hands. However, if you harvest another crop in autumn, you will have three crops in two years or even two crops in one year. There is no need to increase production too much, as long as it is doubled, then the food problem can be solved by itself.

Ordinary people also know the importance of fertilizer. As the saying goes, "A crop is a flower, and it all depends on dung." ”

Cow dung and horse dung in all parts of the countryside have been picked up by the people. Even human urine and urine are collected and fertilized. Each family collects its own, and this is also a treasure.

But even so, the cultivated land in China has been fed by human beings for thousands of years, and there is a great shortage of nutrients. There are not many fields that are carefully cultivated to fertilize the fields, and many people have cultivated the land all their lives, but only to make a lot of hard work. There was not much fertilizer in the fields, and all the crops were harvested. In this era, many places even needed to collect firewood for cooking, not to mention returning wheat straw to the field.

For a long time, the soil has been barren. If you want to improve, you must either plant other crops in rotation to cultivate, or simply abandon cultivation.

In later generations, a large number of chemical fertilizers and pesticides were used, and at the same time, the quality of cultivated land declined faster due to the impact of the industrial "three wastes". The organic matter content of most cultivated land in North China and Northwest China is less than 1%, and the national average content is only 1.5%, while the average soil organic matter content of cultivated land in Europe and the United States reaches 2.5-4%. In order to find a radical solution, the recuperation of the land is one thing, and the reasonable replenishment of fertilizer is also one thing.

As far as the basic situation of China is concerned, the existing cultivated land is most lacking in nitrogen, phosphorus and potassium.

In Meng Xiang's memory, those fertilizer factories with a pungent smell were most nitrogen-based. This is because nitrogen fertilizer is easily lost, and the world's land is prone to nitrogen deficiency. At the same time, nitrogen fertilizer supplementation has the best effect on increasing yield.

In this era, the development of nitrogen fertilizer in China was relatively late, and only two nitrogen fertilizer plants were built in 35 years, one in Dalian, which was said to be in my own hands, and the other was in Nanjing, both of which produced ammonium sulfate. The annual output is only more than 20,000 or 30,000 tons. The highest year was only 41,000 tons, which was not as good as a county-level fertilizer plant that needed to be shut down in later generations.

Since Meng Xiang signed a cooperation agreement with Fan Xudong, he has introduced German equipment and established a nitrogen fertilizer plant with an annual output of 30,000 tons.

Back then, Fan Xudong and Wu Yunchu signed an agreement north of the Yangtze River and south of the Yangtze River, but when they came to Meng Xiang, they were directly ignored by Meng Xiang, and he directly pinched off the germ of these monopoly oligopolies at the early stage. He also cooperated with Wu Yunchu to build a 30,000-ton nitrogen fertilizer plant.

At the same time, in order to have constraints, Meng Xiang also built a 50,000-ton nitrogen fertilizer plant and handed it over to Yang 11 to take care of.

With the prosperity of industry and commerce in the war zone, the power of capital began to rise. Sometimes there are often passive situations, but they cannot be dealt with by the political axe and the army alone. Therefore, Meng Xiang chose some clones to secretly control various industries, and to regulate some aspects as a leader. Not only in the chemical industry, but also in other industries, Meng Xiang has launched nearly 100 clones to control the assets he has directly invested in.

As the vanguard army becomes larger and larger, it is no longer possible for Meng Xiang to treat the vanguard army as private property. That's too much, and that's where a transitional step is needed. As a result, the assets of those arms sales were transferred to these emerging industries and businesses.

Sheep 11 and others are the owners of these assets on the surface. But the actual controller is still only Meng Xiang.

In this way, the production of nitrogen fertilizer in the theater of operations exceeded 110,000 tons at once. Except for part of the powertrain, which was basically obtained from the Germans. But this is still not comparable to those foreign enterprises, and it is incomparable to the output of tens of millions of tons in the future. In later generations, those large nitrogen fertilizer plants had an output of 300,000 tons of synthetic ammonia.

However, this is already a big step forward.

Sheep 11 also invests in chemical plants, not only nitrogen fertilizer plants, but also other fertilizers.

Half of China's land lacks phosphate fertilizer, especially the red soil in the south, which is particularly lacking. However, China's phosphate fertilizer resources are relatively scarce.

The basic total amount of China is not low, and it can be ranked among the top three in the world, but most of them are low-quality phosphate rocks with an average taste of only a dozen percent, and the quantity that can be mined at low cost is too small, and a large number of phosphate rock resources in later generations still need to be imported. Of course, there are also some people in later generations who only value immediate interests, and after frantically digging up a small amount of resources to export to make money, they have to spend a higher price to import.

Again, many minerals at this time are extremely cheap, and the price of phosphate fertilizers is not high at this time. Crucially, after the end of the Spanish Civil War, Meng Xiang obtained the right to mine part of the phosphate mines in Western Sahara.

The richest concentration of phosphate rock resources in the world should be North Africa.

Its Atlas zone is the world's largest phosphate salt deposit, accounting for half of the world's total. Western Sahara is one of them.

The country with the largest phosphate resources in the world is neighboring Morocco, which accounts for two-thirds of Africa's mining volume, and the main production area is Hulibgai.

Phosphate mining in Hulibgai, Morocco, has been mined since the 30s, but it is French territory. However, compared to its reserves of four or five billion tons, the prospects are broad, and for the long-term interests in the future, Meng Xiang is waiting for the best time to enter.

World War II has begun, and the French are about to be defeated. At that time, it was much easier to enter strongly.

Western Sahara is another rich concentration of phosphate rock reserves, with 1.7 billion tonnes of reserves in the famous Bukhara phosphate deposit alone. Although Meng Xiang is not very clear, he knows the general location, it is relatively close to the sea, and no one has developed it for the time being. So I directly drew a big circle, and the cheap ones were picked up by the copycat companies. To be on the safe side, the copycat company was transferred to the Vanguard.

Of course, there are other famous phosphate deposits in Africa, such as Gafsa in Tunisia, Taiba and Palo in Senegal, Safaga and Qusel in the Red Sea region of Egypt, etc., but Meng Xiang does not know much, and the base car cannot pass, so there is no way to find it.

The same goes for potash.

China has always been deficient in potassium, and potassium resources are very limited. In later generations, salt lake potash fertilizer became a sought-after stock. Because of this, potash fertilizer has always been the focus of domestic imports.

In later generations, it was originally a large number of imports, which contributed to the increase in the price of potash fertilizer in the world, and after several well-known reasons in China, even the smuggled goods were raised several times. This made Meng Xiang particularly impressed. Coupled with the Canadian potash fertilizer in the advertisement, Meng Xiang also remembered that Canada's potash resources are the first in the world.

Of course, this ranking is slightly biased, at this time, the Soviet Union has discovered the upper Kam potassium-bearing basin and the Central Asian potash basin in the twenties and thirties, only the potash basin in Central Asia, the prospective reserves of later generations reached more than 30 billion tons, and Canada's potash is mainly produced in Saskatchewan, the potash mine in the Saskatchewan basin was discovered in the 40s, and the potash reserves have also reached 18 billion tons, and it is a rich mineral resource.

Mining is not originally calculated by anyone's total reserves, and some poor ores that are not conducive to mining have no mining value, even if the reserves are large, it is useless. Just like China's iron reserves have been reported to be the first in the world, but most of them are poor mines, so they can only import a large number of them every year, and they are still stuck.

Canada's potash resources are easy to mine. At this time, the land there is unbelievably cheap. There, Meng Xiang's circle is bigger and bigger each time.

It is the backyard of Britain, the United States, France and other countries, and it is impossible to directly intervene, but the shadow company can directly plan, mine and produce there. After simple processing, the semi-finished products can be directly transported to Huaxia.

Of course, Meng Xiang will not let go of the potash resources in Central Asia. Not only potash resources, many resources in Central Asia are very rich, the traces of the Han and Tang dynasties have not been smoothed by history, Meng Xiang also hopes to find back the traces of Chinese civilization there, and carry forward here.

Fertilizer is the food of the land, these three fertilizers are solved, coupled with the soil fertilizer and green manure in the countryside, as well as the careful care of farmers, the abundant yield of the land can be expected.

However, there is one thing that Meng Xiang is constantly reminding himself that the land in China not only needs fertilizer, but also needs recuperation. In later generations, the annual fertilization and the use of pesticides caused the compaction of the land and the extinction of a large number of insects, which caused the imbalance of the ecosystem of the land itself and the loss of soil fertility. In the long run, it is humanity itself that will ultimately suffer.

Therefore, fertilizers need to be reasonably matched and cannot be abused. If it should be fallow, it will be fallow, and when it should be rotated, it will be rotated. Only by giving the land a time to recuperate can it be sustained for a long time.

Of course, at present, Meng Xiang can only look at the present, after all, in the case of limited land, what Huaxia needs is the amount of food, and first solve the problem of food and clothing.

"As for the future, when the territory is expanded, there will naturally be no shortage of arable land." Meng Xiang said secretly.
