The cultivation of corn and sweet potatoes has always been regarded as an important task for a certain period.

It is also a crop in this land that has countless living people, and it is a crop that is both hated and loved.

Love is because it does not pick land, as long as there is a piece of land, it can be planted, and it does not take much labor, and it can be richly rewarded.

Hate because corn and sweet potatoes, especially sweet potatoes, eat too much stomach burning, acid reflux, eat a meal may feel delicious, but can be eaten for more than ten years, eat for a lifetime, then there is no pleasant eating process.

And only a full stomach, due to the lack of other nutrients, it is easy to eat thin and malnourished.

But even so, the industrious flower growers still regard the cultivation of sweet potatoes and corn as a delicate work, and always pursue the highest yield per unit area.

When Yan Zheng was compiling a pamphlet on the cultivation of corn and sweet potatoes, he had to admire the wisdom of the working people, and at the same time he felt a sadness in his heart.

From the end of the Ming Dynasty to China, our people at the bottom survived on sweet potatoes.

They tried their best to grow sweet potatoes and corn, but there was still a famine, and they opened up the mountains, which eventually became owned by the landlords.

This shows that in this land, ordinary people cannot get rich by hard work, and this has been the case for thousands of years.

According to the theory of alienation, this is because the labor of the laborer eventually becomes the constraint on the existence of the laborer.

Because the harder the laborers work, the more surplus value the exploiting class such as the landlords will get, the stronger they will become, the more resources they will have, and the more advantages they will have over the laborers.

Before, Yan Zheng must have thought that this sentence was a bit narrow-minded, but after a few years as the monarch, he was surprised to find that the theory of alienation was very correct.

Just like the Ming Dynasty at this moment, the harder the compradors and the people worked, the more profits Dong Qin would draw from it, and the stronger the strength to deal with the Ming Dynasty.

In the territory of Eastern Qin, the same is true, the more desperate the people work, the more resources Yan Zheng, the monarch, can control, and the army will be stronger.

The stronger the military, the more powerful it is, the more these people will never be able to get rid of this kind of production relations.

Yan Zheng was thinking about this question while writing a booklet.

Immediately, he felt that he must ensure that the people of Eastern Qin could live the life they wanted through labor.

Anyone who blocks and reverses the car is irresponsible to history!

A few days later, the technical manual for sweet potato and corn planting was officially compiled.

According to Yan Zheng's memory of the booklet on the soil law, corn and sweet potatoes can be interplanted.

The key to this is to control the spacing of corn plants, which is usually soybeans.

Interplanting soybean corn will yield higher yields than corn alone, which involves photosynthesis.

Interplanting of corn and soybean can increase the utilization rate of solar radiation by 15% to 20%.

Both crop species can also use the difference in height to create ventilation corridors, which can increase the supply of carbon dioxide.

Sunlight scattering when sunlight hits the underside of the corn plant.

Soybean can also fix nitrogen, which can supplement the fertility of the land to a certain extent, so as to achieve the effect of increasing the yield per mu.

This intercropping technique was widely used in the southern hilly areas of later generations, and the flat land was generally used to grow rice.

The rice is used to pay the grain, and the remaining rice is mixed with sweet potato shreds, corn, and taro, and beans are used to extract oil.

As for the rice, who eats it? Why don't farmers keep it for food, is it not delicious? This kind of question cannot be asked in detail.

"Your Majesty, the economic strategy for Jeju Island has been introduced!"

While Yan Zheng was writing the pamphlet, the discussion of the conquest of Jeju Island in the House of Representatives had also ended.

Several ministers personally took the council and asked the king to sign it.

Yan Zheng took this proposal and glanced at it, and couldn't help but be a little surprised.

Because after discussion, this group of people is actually ready to claim Jeju Island in a dignified manner!

The reason they gave was that Jeju Island was not originally part of the Korean territory, but was historically the territory of the Yuan Dynasty, which exiled many prisoners on it.

At the beginning of the Ming Dynasty, Zhu Yuanzhang also exiled the remnants of the Yuan Dynasty royal family and Zhang Shicheng to Jeju Island.

From this point of view, North Korea is stealing Jeju Island, which is completely contrary to the international law of Eastern Qin.

Therefore, its sovereignty is illegal, and the Ming Dynasty does not care about this status quo, so it is equivalent to the Ming Dynasty giving up its sovereignty claim.

Eastern Qin and the Ming Dynasty signed an agreement on mutual recognition of the suzerainty and vassals, so that the Eastern Qin could exercise the power of the suzerainty against Korea.

This makes it legal and reasonable for Dongqin to claim sovereignty over Jeju Island!

Logically, there is no problem at all! Yan Zhengdu thinks it makes sense, but if there is no cannon, this is a piece of waste paper.

"So, you're not going to occupy it directly, but to make a diplomatic statement first?" Yan Zheng asked.

Ah Ku nodded and said, "That's right! This is not to deal with the Nanyang countries, but the hardcore vassal states of the Ming State, and Korea is deeply bound to our commerce, and almost all of its nobles and nobles have business dealings with us. I think that it is not appropriate to adopt the method of punishment without teaching, we still have to rein in the circle of Chinese character civilization, at least go through all the procedures that should be followed. ”

Yan Zheng thought for a while and said, "What's the point of going through this kind of procedure?" ”

A bitter smile said: "We think so, Dongqin has always maintained a fair image in the Chinese character civilization circle, which is still very important!" If we talk about procedures in everything, we can at least reduce misjudgment and vigilance! We have to make them understand that even if we want to send troops, we will say something in advance! ”

"This is also because the current trade and population gathering are all focused on the Chinese character civilization circle." Ashin answered: "We are also considering whether to relax the restrictions on the naturalization of the Korean people, the king once said that the Chinese character civilization circle is the same language and the same species, and naturalization should be relaxed!" If this article is to be implemented in the next year or two, then the image of Dongqin will be more decent! ”

Yan Zheng looked at An Shan: "You people from the Ministry of Defense also think so?" ”

"We are completely sure of the capture of Jeju Island, and as soon as the diplomatic statement is issued, the fleet can be blocked! When the time comes, the melon will be ripe. Ansan bowed.

Yan Zheng sighed, what they said was very reasonable, but in his heart, he always thought that if he could sneak attack, why should he be above board?

But they can think that the use of diplomacy for direct benefit is not a small step forward.

When the two countries are equal in strength, diplomacy is strength, and when there is a disparity in power between the two countries, strength is diplomacy.

In their dealings with foreign countries, Ashin has naturally learned diplomatic blackmail.

"That's fine! I've approved this proposal, but since this matter has to be informed to Mingguo, I'll take this booklet and sweet potatoes to Mingguo! Yan Zheng reached out and picked up a sweet potato planting manual.

"Why did the king send such a precious thing to Ming Guo?" Ashin was a little puzzled.

Yan Zheng said with a smile: "This is not for the Ming court, but for the people of the Ming Dynasty!" Although we want a technical blockade, we don't care about the spread of this new food crop in the Ming Kingdom! ”

Ah Ku also puzzled: "If the new crops can really produce more food, will there be fewer disaster victims in the Ming Kingdom?" In this way, won't it affect our ability to gather the population? ”

Yan Zheng explained: "This will indeed have a certain impact, but you have also seen that at present, the Eastern Qin has been widely known in the coastal provinces of the Ming Kingdom, and the trend of going to sea has also been formed. Coupled with our continuous infiltration and the help of merchants, the speed and efficiency of population collection will be faster and faster in the future. From this point of view, the population explosion of Ming is good for us in the long run!

Don't forget, no matter how powerful Eastern Qin is, it only has a population of more than three million now. The Ming Kingdom has almost 100 million, and among the 100 million people, even if there are only 20 million couples, then even if there is one more ration, only half a child can live, which is equivalent to five million more people! There will always be people who are willing to come to Dongqin because they don't have land, so the more people in the Ming Dynasty, the better! ”
