In ancient times when food and clothing restricted the population, Liu Zhang was very concerned about farming, took the tuber and inspected it carefully, and his eyes widened: "Red lotus? It can't be, right? ”

"Red Lotus?" Huang Yueying looked at Liu Zhang's face, and knew that Liu Zhang seemed to know again, what a shame, she also claimed to be proficient in farming, and also helped come up with new farming methods, hybrids, intervals, and improved agricultural production, but now she lost to Liu Zhang, who was born in the royal family and seemed to have never been in the field at all.

Liu Zhang carefully observed the tuber, if it was a red lotus, Liu Zhang would never believe it, the red lotus, also known as sweet potato, sweet potato, was discovered by Columbus on the American continent and brought back from the Americas.

The reason why the Ming Dynasty was able to expand from tens of millions of people to 200 million people has a lot to do with the introduction of high-yield crops such as red roots, potatoes and corn.

It is recognized that the red lotus comes from the Americas, but where does this red lotus come from? No, it doesn't seem to be a red let.

Liu Zhang picked open the outer layer with his hand, revealing a dark gray fruit inside, Liu Zhang frowned, the red fruit is white, but the tuber he took is not white, but the ghost knows if it is the reason for leaving it for too long.

Liu Zhang suddenly remembered an allusion, he had seen a plant atlas before, which listed the plants in ancient documents, and there was one species that aroused Liu Zhang's interest, not because of others, because that plant was called sweet potato, which has the same name as the sweet potato introduced from Europe.

In fact, the name of the sweet potato comes from that document.

The document is called "Southern Grass and Trees", and it describes a crop.

Sweet, covered potatoes and the like. Or taro or something like that. The roots and leaves are like taro. It is as big as a fist, and there are those who are as big as Ou. The skin is purple and the flesh is white, steamed and eaten, the taste is like potatoes, and the sex is not very cold.

In the land of the old pearl cliffs, the people in the sea do not cultivate, but dig the land and plant sweetness. Autumn harvest is ripe, steamed and dried and cut like rice grains, stored in warehouses, in order to fill the grain, is a famous grain.

Here is a crop called "sweet potato", which is recorded in it with sweet taste, flat nature, non-toxic, all consistent with red roots, and the planting method recorded in it is broken casually. It also echoes the simple cultivation of red roots.

It can be used as a staple food, and it doesn't need to be managed. All of them are characteristic of red moose.

The only description of the stems and leaves is different from that of the red potato, but it is roughly the same, except that this sweet potato is closer to the shape of taro, but it is by no means a taro.

Most of the characteristics are consistent with the red lotus, only a small part of the red lotus is in and out of the red lotus, so when the red lotus was introduced to China, it was originally called sweet potato, but in some places it was changed to sweet potato, not only the taste of the red vetch is sweet.

The book was written in the Jin Dynasty, long before the Ming Dynasty.

Liu Zhang speculated that the "sweet potato" described in "Southern Grass and Trees" may be a crop similar to red vetch, and it is also said that it was planted by "the land of the old pearl cliff, the people of the sea".

The "old" description is that it was before, probably before the book was written, or even long ago, when it was written, but the author learned that there was such a crop.

And the people in the sea, in the era of the ancient city of Haitou, isn't Haitou also a sea city? The people of Zhuya can grow this kind of "sweet potato", why can't the people of Haitou plant it?

It is likely that this "sweet potato" is an ancient crop that has disappeared for thousands of years, and in the end only some fragments of words remain, which cannot be verified.

If the tubers in this jar are really the "sweet potato" recorded in the "Southern Grass and Trees", then it has at least several characteristics, the first is that it is easy to grow, whether it is drought and flood resistant, or both, it is uncertain.

The second is that the output is large, which can be used as a staple food.

On these two characteristics, whether it is red lotus or not, whether it is the sweet potato described in "Southern Grass and Trees", Liu Zhang feels that it is worth a try, if the attempt is successful, it is definitely an outstanding contribution to the Chinese nation.

The average yield of hybrid rice per mu is 1,000 catties, pumpkin is 3,000 catties, the yield of red lotus is 4,000 to 6,000 catties, and it can reach 5,000 catties in general places.

Such a huge yield per mu is the reason why pig breeding has become popular since the introduction of red lettuce, and it is also the reason why the countryside uses red moss to raise pig fat, even in the eighties when the food was not abundant.

If the planting is successful, this jar of tubers is worth 10,000 times more than a jar of gold, Liu Zhang didn't know if he guessed right, and he didn't know if he could plant it alive, so he immediately asked the soldiers to seal it, and directly named it Hongjiao.

Then some seeds were found in the temple, but there were no surprises, beans, winter melons have begun to be planted, only peanuts, now the peanuts of the Han are gray, and the particles are small, but the peanuts here are dark red, indicating that they should have been red a long time ago, and the particles are also large.

Liu Zhang ordered people to carefully take away the pumpkin seed jar, the red lotus jar, and the peanut jar.

Walking to the apse, in addition to some housing, there is only one hall with many spiritual seats, Huang Yueying knows the text on it, it turns out to be Sanmiao writing, this is the genuine Sanmiao text, not Liu Zhang's nonsense "Sanmiao number" and "Sanmiao science".

From these spiritual positions and the hexagrams on the side, Zhan Hailan and other Loulan people knew that they were also descendants of Sanmiao, who had migrated from the Central Plains before.

Although the palace is very splendid, it is only a small country after all, and it cannot be compared with the Central Plains Palace.

I was so angry that I only took away a few jars, and said to Liu Zhang: "Lord, I think we should move all these gold, silver and jewelry, it's a big deal to leave a little for the people of Loulan, you can buy a lot of food." ”

"Do you think that where there is gold and silver, there is food?" Liu Zhang asked.

"Isn't it? Not to mention anything else, the gold masks for those statues here, according to the highest price of our Han now, a gold mask can be exchanged for thousands of loads of grain, which is still broken and sold, I think the gold mask has a very high artistic component, maybe it can be worth hundreds of thousands of stone grain. ”

Liu Zhang looked at it in surprise, this girl still understands the art component. He smiled and said: "The market price of grain is determined according to the relationship between supply and demand, and the peasants have produced so much grain, and the reason why the price is like that now is because gold and silver have not flooded, and not all of them have poured into the grain market."

If we take all these gold masks and melt them to buy grain, then the gold and silver will be overflowing, and all of them will flood into the grain market, not to mention that the price of those grains will rise sharply, and people themselves will not have enough to eat, how much will they sell you? ”

"This ......" was so stunned, but Huang Yueying on the side looked at Liu Zhang in surprise, she thought that she was omnipotent, and her lord was really omnipotent, from the royal family, how could she understand so many things of three religions and nine streams?

Liu Zhang shook his head and said: "Our Sichuan army originally had more money and less grain, and now we are buying Cao Sun's grain in large quantities, which has pushed up the price, and the two sides have controlled the sale of grain.

If we take out more gold and silver to buy grain, it will not do us any good, we can only waste money and give it to Cao Cao and Sun Quan in vain. ”

"Oh." I touched my head so badly, and I was ashamed.

"Forget it, these statues, masks, golden cranes, jade steps, reliefs, jade, all of them are things left by the ancients, keep them, and leave a memory for our children and grandchildren."

"Oh." I can't exchange food, and I don't know what these gold, silver and jewelry are used for.

Liu Zhang walked towards Zhan Hailan and said to Zhan Hailan: "Your Majesty, the things here are rare and abnormal, they are all left to you by your Loulan ancestors, and they are also the wealth left to the entire Chinese nation. ”

Huaxia in the narrow sense is the descendants of Yan and Huang, but as long as you have a little common sense, you should know that Chiyou should also be included in Huaxia, so the Sanmiao people are naturally Chinese people, and the wealth left by Loulan's ancestors is also the common wealth of Chinese people.

Zhan Hailan listened to Liu Zhang's words and breathed a sigh of relief, from seeing these gold, silver and jade, Zhan Hailan was worried that Liu Zhang would take it for himself, but he didn't expect Liu Zhang to be willing to hand these over to them Loulan people, Zhan Hailan was very grateful to Liu Zhang.

As for those stocks of gold and silver, of course Zhan Hailan also wanted it, but the Han army first restored the country for Loulan, and then saved so many Loulan people in this land trap, and this place was also opened by Latia, even if it was because the Han was now the complete suzerainty of Loulan, it was impossible not to share the benefits to the Han.

You can't really just give people a few broken jars.

The Loulan people care more about the relics of their ancestors, and the gold and silver in those stocks can only be equivalent to currency, so they don't care so much. Liu Zhang's conditions are acceptable to Zhan Hailan.

But Zhan Hailan immediately made a mistake again, so many priceless relics, how can the people of Loulan protect them? Don't look at the fact that the Western Regions have been stabilized by Liu Zhang, but if the news that the people of Loulan have so much wealth spread, they will not lose the country in ten years, and they will definitely lose the country in a hundred years.

And now that the soil erosion in Loulan is becoming more and more serious, it is certain that the national strength will become weaker and weaker, even if no one fights Loulan's idea, Loulan will destroy it by itself, and what will happen to this wealth at that time?

Seeing Zhan Hailan frowning and silent, Liu Zhang said to Zhan Hailan: "Your Majesty is worried that the people of Loulan will not look down on these wealth?" Or is Loulan about to die? ”

Regarding the demise of Loulan, no one here is more aware than Liu Zhang, even those Loulan people who are struggling on the edge of water shortage now could not imagine that the city they live in now will become thousands of miles of yellow sand in a few hundred years.

Loulan was bound to die out, and Liu Zhang remembered that during the Jin Dynasty, Loulan needed the Han Dynasty and Gaochang in the north to give them water aid, and the population was drastically reduced.

Zhan Hailan nodded.

Liu Zhang said: "Many countries in the Western Regions have relocated the country because of desertification, and this time Shache has also moved to Luntai because of the war, I heard that the people of Loulan have been living here because you want to find the ancient city, and now the ancient city has been found, do you still have any mission?" ”

"Huh?" Zhan Hailan looked at Liu Zhang, shook his head, and suddenly thought, yes, now the ancient city has been found, but in addition to a lot of precious artworks, what more people in Loulan have? (To be continued......)
