A northwest wind blew, and the temperature in Chang'an City dropped suddenly.

The ginkgo tree outside the courtyard of the Chu Wangfu has long been left with only smooth branches.

"Bang bang!"

"Boom!"

With the sound of hurried horses' hooves, Yu Chihuan and Fang Yiai appeared at the door of the courtyard of the Chu Palace.

These two guys used to be frequent visitors to the Chu Palace, and the porter naturally recognized them.

Even if they are already tanned, they are recognized at a glance.

"Hurry up and report to the prince, Yu Chi Saburo and Fang Erlang are back."

After Menzi gave an order, he immediately stepped forward to greet the two bigwigs.

……

In the vegetable field of the courtyard of the Chu Wangfu, Li Kuan was watching the people harvest this year's vegetables with small corn.

Although many people in Chang'an City followed suit and began to grow woad, the scale of the Chu Wangfu was still the largest.

On the one hand, it is to ensure that the palace itself has vegetables to eat in winter, and on the other hand, it can be regarded as leading by example to strengthen the confidence of people who are still waiting.

"Ayah, wead, baby corn hug."

The little girl who is more than a year old can already communicate with Li Kuan simply.

This made Li Kuan and Cheng Jingwen very pleasantly surprised.

Although there are many children who can speak earlier than her, it is still much faster than ordinary people to use conjunctions to communicate simply when they are more than a year old.

Some slow children are not very willing to talk after the age of two.

"This dish is too heavy, Aya will help you hold it."

There is no danger in the vegetable field, and Li Kuan is also relieved to let the little corn play in the vegetable field.

And Cheng Jingwen watched this scene from the side, and she was also very happy.

I have always been worried that I will give birth to a daughter, and Li Kuan will not like it.

Now it seems that Li Kuan said that he liked his daughter, but he really didn't lie.

"Lord Wang, I have planted so many herbs this year, and I heard that many noble families have also planted them, so it is estimated that everyone should not be so annoying about the winter in Chang'an City."

Cheng Jingwen witnessed the changes brought by Chinese cabbage to Datang, and this change was brought by her husband, and a sense of pride arose spontaneously in her heart.

"It's still too little, there is only one kind of Chinese cabbage, and everyone will feel tired of eating too much. The cost of greenhouse planting must be reduced. ”

Whether to promote glass-making technology on a large scale, Li Kuan has not yet thought about it.

In order to let more buildings use glass windows and let more greenhouses be built, then the promotion of glass is a must.

However, once the technology of glass spreads, whether it is glass mirrors or various so-called crystal crafts, the price will definitely fall sharply.

Although there is a threshold for turning glass into a mirror, once the biggest problem of glass is solved, there will always be other homes that can make mirrors.

"Lord Wang! Rajah! ”

Before Li Kuan could think too much, someone rushed in the distance.

"The fleet of the East China Sea fishery under the South Seas has returned, and Yu Chi Saburo and Fang Erlang have already arrived at the palace."

"The fleet is back?"

Li Kuan inquired, and a smile immediately appeared on his face.

In addition to the wealth brought by spices, he was looking forward to the rice from the South Seas.

"Jingwen, let's go, let's go back first."

Li Kuan was in no mood to pay attention to the harvest of the herbs, so he quickly picked up the little corn and sat in the carriage on the road next to him.

There is a saying that before you see it, you hear it.

Before Li Kuan arrived at the door of the lobby, he heard the voices of Yu Chihuan and Fang Yiai talking from a distance, and there were occasional inquiries from Wang Xuance.

"Haha, Brother Wei Chi, beloved, you're back!"

Li Kuan also ignored so much etiquette and stepped forward to give the two of them a hug.

When going to sea in this era, it was really risking life.

Even if there is a clipper, a compass, and a chart, the risk is much higher than that of future generations.

To put it mildly, every time I go to sea, especially when I go to the South Seas, I go to the ghost gate once.

"Lord Wang, fortunately not disgraced!"

Yu Chihuan's rare text crepe came with a sentence.

"Lord Wang, this time our fleet has returned with a big victory, not only pepper, cinnamon and nutmeg, but also a lot more anise than last time."

Fang Yiai's love is like a child asking his parents to ask for credit, telling the receipt of this trip.

"Fennel?"

Li Kuan's eyes lit up, this is also a good thing.

All kinds of braised meat, especially braised duck legs, braised duck feet, etc., if there is no anise, how can it be a shortcoming.

The most important thing is that, unlike cinnamon and nutmeg, which mainly play a role in removing the fishy smell, aniseed has a great function, which is to hide or remove the unfreshness of the meat.

To put it bluntly, in this era, due to the lack of refrigerators, many meats are sometimes not so fresh, and if you add aniseed to cook together, it is not easy to eat unfresh.

Of course, whether you are healthy or unhealthy is another matter.

At least, whether in the Tang Dynasty or in the grassland, anise should be very marketable.

"That's right, my lord, that spice island is really a treasure island. Last time we didn't find fennel because it wasn't in good season, there was no anise on the tree and we didn't know the aniseed tree. At this time, we directly brought a few guides who were familiar with spice trees, and found that there were many surprises on the spice island. ”

Yu Chihuan watched Fang Yiai's spitting introduction from the side, as if he had reacquainted Fang Yiai.

This guy, why didn't he find out that he could say so much before?

"Did you bring back the rice I told you about later?"

Listening to Fang Yiai say that it was all about the spice island for a long time, Li Kuan couldn't help but be a little worried, they didn't think that the value of rice was too low, and they used the space on the ship to load spices, right?

"Yes, of course."

Speaking of rice, Fang Yiai showed a regretful expression on his face, "Lord Wang, it's a pity that we used half of the ships to load rice from Linyi, Champong, Zhenla and other places." ”

"Yes, my lord. We also ate some rice made from Nanyang rice, but it was not as delicious as the polished rice of the Japanese country, and the texture was very rough and hard. I don't understand why you let us transport as much paddy back as possible. ”

finally had the opportunity to complain, and Wei Chihuan naturally spit out bitterness with Li Kuanda.

"You're bringing back rice, not rice, are you?"

Li Kuan hurriedly confirmed again.

These foodies know how to eat all day long.

If they thought they wanted to eat Nanyang rice too, and all they brought back was rice with the husk removed, then they would really want to cry without tears.

I want rice seeds.

"Don't worry, Lord Wang, you said that it was rice, and we naturally bought all rice. It's just that the ship is relatively wet, and it's hard to say if it's broken. ”

Seeing that Li Kuan seemed to be very nervous, Yu Chihuan felt a different atmosphere.

"Lord Wang, could it be that there is something unusual about these rice?"

Wei Chihuan carefully recalled the rice in the cabin, and couldn't think of any difference from what he saw in Chang'an City.

"Of course it's not ordinary, you two have made great contributions!"

Li Kuan's mood was relieved, and a smile appeared on his face.

……

During the Zhenguan period, corn was the most grown in the north, followed by wheat, and then sorghum. However, in the Jiangnan region, rice cultivation has become more common, and it can be said that it is the main food in the local area.

This structure is already a bit similar to that of later generations.

The main difference is that corn still occupies the dominant position at this time, and in later generations, it has basically been marginalized.

In later generations, except for wheat and rice, the others were called miscellaneous grains, which fully reflected the importance of these two kinds of grains.

However, Li Kuan found that almost no one planted rice in the entire vicinity of Chang'an City.

Even in the south, rice is grown once a year and has a very low yield.

So when the East China Sea fishery went to the South China Sea again, Li Kuan immediately went to bring back a large amount of rice.

"Lord Wang, I don't see anything unusual about these rice? Where is it not ordinary? ”

Fang Yiai looked at Li Kuan in confusion.

In his opinion, no matter where the rice is produced, isn't it all the same?

"You've been in Nanyang for so long, haven't you noticed any difference in their rice?"

Yu Chihuan and Fang Yiai glanced at each other, and then shook their heads very tacitly.

"Then have you noticed that the price of rice in Nanyang is much cheaper than that in Datang?"

"Lord Wang, we know this. And, when we were in Linyi, we found that although the people there were generally short and small, we heard that very few people died of starvation. ”

Wei Chihuan thought about the scene when he bought rice in the Linyi market, those Linyi people were so happy, they had never seen anyone buy rice in such large quantities, and they almost bought all the rice in stock in the entire street.

"Have you ever wondered why? It can't be that the people of Linyi are more industrious than us people in the Tang Dynasty, right? ”

"How is it possible, those people are too lazy to be like monkeys, idling around all day."

Fang Yiai felt that many of the people in Nanyang were wandering around with nothing to do, but some peasant women could be seen plowing in the field from time to time.

"Those people are so lazy, and they rarely starve to death. And our people in Datang are very hardworking, but once they encounter a famine, few of them can survive it easily, haven't you thought about why? ”

Being asked by Li Kuan, Wei Chihuan and Fang Yiai finally realized that they seemed to be missing something.

Could it be that it has something to do with these paddies?

There was a moment of silence in the lobby.

"Lord Wang, the rice yield of Linyi Country is much larger than ours?"

Wang Xuance on the side asked tentatively.

"That's right, isn't it that Linyi's rice yield is relatively large?"

Wei Chihuan also felt that Wang Xuance's speculation seemed to be able to explain Li Kuan's problem.

In Datang, the yield of one mu of ordinary farmland is only about one stone, and only a good good field can solve two stones.

This stone is about equivalent to one hundred and twenty catties now.

In later generations, the highest yield of rice per mu has exceeded 2,000 catties.

Of course, the yield of rice produced in this special experimental field is of little significance.

But even if it is hybrid rice planted by ordinary farmers, there is no problem at all if the yield per mu exceeds 1,000 catties.

With such a comparison, everyone knows how low the grain yield per mu was when Datang was in the past.

It is no wonder that Wang Xuance thought about rice yield so quickly.

"Xuan Ce, you're half right. Whether it is Linyi or Zhancheng, their rice yield is indeed higher than ours, but at most it is a few percent higher. ”

"Lord Wang, a few percent is already very remarkable."

Wang Xuance showed an excited look on his face.

"No, it's not the most remarkable, Nanyang rice, it can grow twice a year, or even three times a year, that's the most important thing."

"One...... Three crops a year? ”

Wang Xuance looked at Li Kuan in disbelief.

Growing up, he had never heard of any other grain that was harvested three times a year.

Whether it's corn, wheat, or rice, aren't they all harvested once a year?

At this time, even Yu Chihuan and Fang Yiai felt that the rice they brought back seemed to be very difficult.

"That's right, people's rice can be double-cropped or triple-cropped, so people there don't go hungry easily."

Li Kuan thought of the countries around Nanyang, and if you want to talk about the geographical location, it is really good.

There is no severe cold all year round, and the yield is very good when you grow some fruits and grains.

But if you are industrious, it is not easy to starve to death.

"Then if all of our Datang are converted to rice, wouldn't the grain output be several times greater?"

Wang Xuance's eyes lit up, and his excited hands trembled a little.

Even Yu Chihuan and Fang Yiai were excited in their hearts.

If that's the case, I'm going to go down in history, right?

Bring such an important seed back to Chang'an City from Nanyang.

"How is it possible, how can there be such a good thing!"

Li Kuan's words were like a basin of cold water, splashed directly on everyone's heads.

However, after a few moments, they all showed confused expressions again.

It is you who say that the yield of Nanyang rice is high, and you are also the one who says that other people's rice can be double-cropped or even triple-cropped.

But you said that it is impossible for Datang's grain to increase several times, isn't this inconsistent?

I've also studied arithmetic.

"The climate of Nanyang is blessed with warm all year round, so it is possible for rice to be triple cropped. But if it is placed in Datang, except for the area near Yazhou, which can be three crops, the other areas in the south of the Yangtze River can only be two crops. Put it in the Guanzhong area, if the variety is selected well, it can also be harvested twice a year. In places such as Hebei Province and Henan Province, most of them can only be cooked. ”

Li Kuan explained this, and Wang Xuance and the others understood.

"Lord Wang, even so, it is completely worth promoting."

"Of course, how could I have wasted precious capacity to load paddy?"

Li Kuan didn't want to breed in a greenhouse for several years like promoting woad.

For Datang at this time, it is necessary to directly plant tens of thousands of acres of rice to see which type of seed has the highest yield, and to promote it according to which one.

Anyway, the horizontal and vertical are better than the rice in Datang at this time.

As for the rice in Linyi, the rice in Zhancheng and the rice in Zhenla, which one is more suitable for Datang, it will be slowly discerned in the future.

Anyway, the rice that is being transported back now is available from all over the place, and if you really have to distinguish it, no one can distinguish it for a while.

Therefore, Li Kuan is going to simply change the rice in the land of the Chu Wangfu first.

When next year's rice yield comes out, it makes sense to talk about the promotion of rice.

After all, in this era when having food to eat is to press everything, even Li Shimin did not dare to arbitrarily order the large-scale promotion of a kind of food.

If something goes wrong, the farmers will really come up with it.

When a person has no food to eat, he will do everything.
