In Suzhou, an agricultural research team came to the fields.

They are doing the latest research, pipe irrigation.

They will conduct experiments on this land to verify the feasibility of low-pressure pipeline irrigation.

Low-pressure pipe irrigation means an irrigation system that uses iron or plastic pipes instead of ditches to transport water.

Compared with ditches, pipe irrigation can reduce infiltration and evaporation and increase water use efficiency. At the same time, some arable land can be saved.

A ditch is at least half a meter wide, and one mile is almost an acre of land.

The pipeline basically does not take up space.

Of course, with Dahua's current technological level, the cost of using pipes is actually slightly higher than that of traditional water channels.

However, when Dahua's manufacturing industry is upgraded to another level, that may not be the case.

Nowadays, Dahua has no plans to lay large-scale pipes for irrigation. This scientific research team only comes to experiment first to obtain experience and data.

When the conditions are ripe in the future, it will be in place in one step.

Things that are not needed now must be researched first. This is a common practice in the scientific research community, and Dahua has always done this.

For example, those drilling rigs started research and development five years ago, and started large-scale manufacturing two years ago.

At that time, the imperial court did not actually plan to drill a large-scale deep-water well in Hebei.

In the Central Plains, water conservancy projects are in full swing.

And overseas, water conservancy construction has never stopped.

In areas such as the Ganges Plain, the Indus River Basin, the Mississippi River Basin, Jakarta and other important grain-producing areas, water conservancy projects have been under construction and agricultural technology has been promoted.

The three lifebloods of water conservancy, seeds, fertilizers and agriculture.

In the 18th year of Yongxing, Dahua's annual output of chemical fertilizers reached 15 million tons. Among them, 10 million in the Central Plains area and 5 million tons in overseas areas.

The 10 million tons in the Central Plains is about equal to the level of later generations of flower growers in 1978, far surpassing other fields.

In other fields, the level of development of Dahua Central Plains is at most 50 years of the 20th century.

The reason why the fertilizer sector has developed so fast is mainly due to Wu Changqing's attention.

As early as the second year of Yongxing, he spared no expense to exchange various types of fertilizer synthesis technology.

After more than ten years of development, Dahua's fertilizer synthesis technology is now very mature, the manufacturing process is quite exquisite, and the manufacturing cost is quite low.

The annual output of five million tons in overseas regions is much less.

Dahua’s overseas territory is almost nine times that of the Central Plains region (the Central Plains region here refers to the 9.6 million, including the west).

The area of ​​arable land is almost seven or eight times as large, and the population accounts for half.

With an annual output of five million tons, it is far from meeting that huge demand.

However, the output of chemical fertilizers in overseas regions is growing rapidly, and the growth rate far exceeds that of the Central Plains.

For example, in India, the annual growth rate of chemical fertilizer production in Yongxing in 17 years reached 25%, while that in the Central Plains was only 10%.

Of course, in terms of growth rate, the fastest growth rate is in North America, and here will continue to maintain the crown of fastest growth rate.

After all, the start here is too low.

As Dahua’s largest granary, North America’s current annual output of chemical fertilizers is less than 100,000 tons.

This is all because North America was late in recovering, and the corresponding construction was even later.

In the 17 years of Yongxing, the first fertilizer plant appeared in North America.

However, these have a huge amount of arable land, and there is a huge demand for fertilizer.

Therefore, there are a lot of fertilizer factories under construction here, and those businessmen, like sharks that smelled blood, had already threw their capital to North America before Philadelphia had fallen.

Dahua did not oppress the capitalists and the rich in North America. However, when they faced the capital invasion of the Central Plains, they still steadily retreated and their wealth shrank greatly.

The industry they were engaged in before quickly became an unprofitable field.

And fields such as fertilizer plants, steel plants, and oil refineries are either controlled by the Dahua government or by the Central Plains businessmen. It is difficult for North American capitalists to squeeze in.

Their best choice was to cooperate with a Central Plains businessman, and they would contribute 100% of their capital, and then the Central Plains businessman would give out some technology, and the two would split between the two.

Central Plains businessmen account for 70%, and they are relatively soft-hearted Central Plains businessmen.

If unfortunately encounter a ruthless character, the capitalists on the 28th can only accept it with tears.

For them, don't think about getting rich and increasing their wealth. It's thank goodness to be able to keep their wealth without shrinking.

Through this relatively gentle method, Dahua has also completed complete control of North America.

There are still rich white-skinned people, but there are not many whites who can have a final say and have great influence.

Wu Changqing vigorously promoted the development of agriculture, on the one hand, for the sake of filling the whole world, and on the other hand, for the sake of more population and more technology.

However, what he didn't expect was that this policy made the situation of Dahua Overseas become very stable.

It is not easy to completely rule a place.

In the conquered places, there will often be some resistance.

However, in places conquered by Dahua, the number of resistances that broke out was relatively small, and the scale was very small.

There were not even more than ten cases that could be reported to Wu Changqing.

Most of the rebellions did not exceed five thousand people, and the local defenders or security teams put them out.

And for more than 5,000 people, it was only seven times, including two in Fusang, once in Annan, and once in Bangalore...

The biggest rebellion was also launched by miners, not farmers.

This should all be attributed to this food policy, precisely because it is the food policy that allows everyone in the world to eat well, and those talents are unwilling to go against it.

The low-level people may have a smaller structure because they are ignorant and educated, but it does not mean they are really stupid.

They will compare what days they have lived before and what days they have now.

Obviously, the days are better now.

Give up better days to rebel?

I lost my head, and I went back to the hard days of the past.

This choice is awkward at first glance.

Not to mention that people in this era don't have such a strong national consciousness. Even if some people don't like to be ruled by Dahua, no one is willing to do it in the face of such a victory and defeat without good results.

Some people even know that some people want to rebel, fearing that those people will succeed, instead they choose to report to the official.

A small number of careerists cannot inspire the people, so they can only sigh secretly.

They are not so stupid if they need to charge and fight themselves.

When facing Han people, they are even more humble than ordinary people, and they almost never lick their shoes.

With the longer and longer time being ruled by Dahua, people in some areas have begun to completely regard themselves as a part of Dahua.
