The Head of the Ming Dynasty Spared His Life

Xu Guangqi's "Nongzheng Quanshu Sweet Potato Shu" is an important historical material for the study of tuber crop sweet potato planting. "Sweet Potato Shu" comprehensively discusses the introduction and promotion of sweet potato varieties, field management, selection and storage, processing and eating.Even in modern times, this paper has very important scientific significance.

You must know that the sweet potato hadn’t spread to Ming Dynasty at this time, and Xu Guangqi was able to write such a detailed paper only after hearing some characteristics of the sweet potato described by himself. Yan Song felt...

Your sister, a top student is a top student, and I will never understand the world of a top student.

But unexpectedly, in Annan, I came across the sweet potato that was handed down?

This made Xu Guangqi very cold.

Seeing that Xu Guangqi didn't leave anyway, Yan Song understood Xu Guangqi's meaning with a move in his heart.

You know, sweet potatoes are a good thing.

In Daming, the main grains today are wheat and rice.The staple food of the basic north and south.

However, whether it is rice or wheat, there are very high requirements for food planting conditions.Needless to say, rice must be grown in places with warm water, and wheat cultivation also requires a lot of water.

However, on the vast land of Ming Dynasty, the vast western and central regions were seriously short of water.There are also terrains such as tidal flats and barren mountains, which make it impossible to grow rice and wheat on a large scale.

How to do?

This is also a problem that greatly affects grain production and population in Ming Dynasty.

The total amount of arable land in Daming today is about 7 million mu, but there are less than one-tenth of the high-quality fields with irrigation systems and sufficient water.

The remaining 9% of the land is middle and low-grade fields, and the yield of traditional crops is very low.

But sweet potatoes are different.

Sweet potatoes are drought-tolerant plants. If they are planted in dry land, sweet potatoes will grow better!

After having sweet potatoes, nine tenths of the arid land in Daming immediately turned into a high-yield fertile field with a mass production of over 200 jin!

And Daming's grain output can be improved by leaps and bounds.

Xu Guangqi stroked the sweet potato, trembling with excitement: "Mr. Yan Ge, this thing is no different from a revolution in the grain industry for my Ming Dynasty. As long as sweet potatoes and corn can be introduced, my Daming's grain and The population will increase dramatically!"

".々Okay, I will arrange someone to promote it." Yan Song nodded.

Yan Song is now expanding his territory, but there is a problem that has been bothering him.

That is, the population of Daming is not large enough.

Although the 1.6 million population of Ming Dynasty is definitely the largest country on Earth in this era, but Mr. Yan Ge has no choice but to continue to expand the territory, and the territory of Ming Dynasty is increasing rapidly.And Yan Song also wants to bring the entire land of North America, South America and Australia into the rule of Ming Dynasty...

Mr. Yan Ge continued to immigrate in large numbers overseas...

This caused Daming's population to make ends meet, not enough to use.

Now, with this high-yield food crop sweet potato, Yan Song's worries are easily solved.

Another advantage of sweet potato is that it does not require a lot of manpower, and it can grow well on its own (the king's).

As long as sweet potatoes are planted in time and given some water, they don’t need special care or even weeding much, and they can harvest high yields in autumn and winter when they are harvested.

Compared with rice and wheat, which need to be carefully cared for, the advantages of sweet potatoes are unparalleled.

Yan Song called a Ming official from Champa and asked, "How did this sweet potato come from?"

The official looked bewildered, thinking that Yan Ge always wanted to investigate the fault of this kind of "weed" growing in his field, so he knelt on the ground in fright and wept:

"Excuse me, Mr. Ge! I don't know. I only know that some Spanish businessmen's wives seem to like to grow this South American crop. As an ornamental, it seems that when they passed by here, they accidentally discarded or dropped some of them. It grows on the ground."

Yan Song nodded.

About the origin of sweet potato...

After the Ming Dynasty and Europe colonized the Americas, some businessmen traveled all over the world and brought some crops native to South America to countries in Europe and Asia, which promoted the spread of crops around the world.

And this kind of dissemination is undoubtedly beneficial to Daming.

"Don't panic, this kind of plant is not a weed, it is very beneficial to the Ming court!" Yan Song said to the weeping official.

"Huh?" The official looked confused.

This is not a weed?

Don't hold me accountable?

What the hell did I just say?Hey, if I knew it earlier, I would have said that I introduced it, so that I could be promoted to the rank of official.

Thinking of this, the official regretted so much that he fainted in the toilet.

Yan Song: "I want you to investigate, if there are any strange plants here in Zhancheng, you have to tell Master Xu Guangqi. Let him distinguish whether it is useful. I will give you a credit!"

The official was overjoyed.This is a big pie from the sky.

"Strange plant, I'll ask someone to investigate carefully!"

The official ran out in a pissed off manner.

At around 690:[-], the official called a group of old farmers and told Xu Guangqi about the suspicious plants in the surrounding fields.

After some investigation, Xu Guangqi confirmed that a special plant native to South America—tomato—has also spread to Annan.

"Oh, tomato, tomato!"
