"Diversity?" Li Jing and Li Shimin glanced at each other, and what Tang Ping said knew the meaning of each word separately, but when they were together, they were ...... I don't understand much.

"Yes, even the food source of Datang is too single, which has caused the ability to resist disasters too low."

Tang Ping took his mobile phone and read word by word: "Therefore, we should try our best to make the people of Datang have more food choices." ”

"More food options?"

"That's right, I think the planting of potatoes should be put on the agenda in advance."

Originally, it was planned to let the Datang officials see the yield of potatoes before promoting them nationwide, but the advent of the locust plague let Tang Ping know that the potatoes were planted ahead of schedule.

In terms of time, if he returns to modern times and brings back a large number of potatoes this time, and then starts to plant them on a large scale, the time when the locust plague occurs is about the time when the potatoes are ripe.

In this way, even if the locusts can eat the potato leaves by then, the potatoes buried in the ground can become life-saving food.

However, it depends on the courage of the Tang Dynasty, after all, large-scale cultivation of potatoes requires a certain amount of farmland and manpower.

This will inevitably affect the cultivation of other foods, and the replacement of the original crops with a new crop of unknown yield will inevitably be a great resistance.

Li Shimin nodded: "I will try my best to promote this matter!" ”

Although he is the emperor of the Tang Dynasty, can the emperor really manage what crops are planted in everyone's fields?

It can be said that this matter must be difficult, but he also knows that if it is really as Tang Ping said, it is the people's greatest chance to live.

"Anything else?" Li Jing asked, he also knew that although Tang Ping only had a few words about the two points he could say, it was definitely not easy to do.

"There's nothing else for now."

"Okay, General Li, let's go back to ...... right Enter the palace! Li Shimin stood up, thought about it and said, "Thank you, little brother Tang!" ”

"No more than polite! If the imperial court is willing to plant potatoes on a large scale, please go to the village of Shanghe after the sixth day. ”

Five days later, it was the day he returned to modern times, this time to bring as many crops as possible that were less affected by the locust plague.

As for the ways to stop and control locusts in the future, such as pulling insect nets and the like, we can only talk about it slowly.

Li Shimin and Li Jing hurriedly returned to the palace, and at this time, the Xiande Hall had already been called over by Fang Du and the two ministers.

From Gao Shilian, the secretary of the Ministry of Rites, to Duan Lun, the secretary of the Ministry of Industry, the six books are all here, plus Wei Zheng, the inspector of the school, has already been the provincial officials, and the most powerful people in the entire Tang Dynasty are basically concentrated here.

"Where did this news come from?" The head of the household department asked, he was in charge of the household department, and Fang Du and the others talked about the locust plague, and he thought it was very possible if he thought about it, but he still wanted to know who said the news.

Fang Du and the others looked at each other and shook their heads, they were also very curious, but His Majesty didn't say it, how did they know.

Just when everyone was talking, Li Shimin came back with Li Jing.

"Everyone knows about the locust plague, what can you do?"

Sitting in his place, Li Shimin looked at the ministers below.

Dai Zhou was the first to come out of the ranks, and this matter was originally his job: "Please give an order to your majesty to let the people hunt and kill more." ”

This time, he was smart and didn't say anything about worshiping the locust god and asking His Majesty to accuse the heavens of sin.

Manpower hunting and killing is also a commonly used method of exterminating locusts in this era, and there are various methods such as smoking and burning.

However, this method is actually only effective for small-scale locust plagues, and once the scale is too large, the manpower is insignificant.

"What else?"

This time, Dai Xuan didn't speak, because he had just one way, and as for the others, they could only look down at their toes.

Li Shimin was a little helpless, not to mention the civil and military affairs of the Manchu Dynasty, at least the people in charge of the Central Committee of the Tang Dynasty were all here, but no child had any knowledge.

Well, Tang Ping was directly classified as a child in his place.

"Since you can't think of a way, then I will say two ways, and you will discuss how to promote it."

Li Shimin directly did not ask whether these two methods were feasible, but asked them to directly discuss how to promote them, which is already very revealing.

"First, promote it nationwide, raise ducks!"

"Ducks?"

"Nationwide rollout?"

The people below didn't figure it out, didn't they say the locust plague? Why did the emperor suddenly mention raising ducks?

Li Shimin looked at his executives below who were amused and angry, and talked about Tang Ping's ducks' restraint on locust larvae and the benefits of raising ducks.

He is not like Tang Ping, he still has to read it according to his mobile phone, what Tang Ping said, he can basically repeat it after listening to it.

"So ducks still have such a role?"

"It seems really okay to think about it! The locusts can't fly when they're young, and they're the food for chickens and ducks. ”

"It's such a simple thing, why didn't everyone think of it?"

I have to say that this group of people is still very receptive, and after communicating, they quickly accepted this plan.

But they accept that it is useless, and the hardest thing is to implement.

If nothing else, if you want to breed ducks, you must have duck seedlings, right? This is not a one-family breeding, but to be promoted nationwide, then these duck seedlings are an astronomical number.

That's the biggest problem with this solution.

At this time, Lu Kuan, the secretary of the Ministry of Rites, stood up: "Your Majesty, when the minister went to Dongyue, he saw that there were many chickens and ducks raised among his people, and this time he needed so many duck seedlings, and it is estimated that only Dongyue has so many." ”

"But our relationship with Dongyue ......" Wei Zheng's words were not finished, but everyone knew that the relationship between Datang and Dongyue was not good.

Well, to be precise, the relationship between the Tang Dynasty and the surrounding countries is not very good.

The reason for this is because everyone turned out to be the courtiers of the former Sui, and the former Sui had no way, and the smoke was everywhere, and all walks of life held high the banner of righteousness.

After attacking each other, they established countries one after another.

The Tang Dynasty occupies the Chang'an Prefecture in Guanzhong, which is also the former center of the Great Sui, so it often regards itself as orthodox, and the surrounding countries are naturally not too convinced.

Although they have no longer fought against each other in the past few years, it is just because they need to recuperate.

At the beginning of the Turkic siege, Chang'an's troops were overstretched, also because the border pressure of the surrounding countries was huge, and once the defense was neglected, it was likely that the other party would take advantage of the weakness.

So now if you want to trade a large number of duck seedlings with Dongyue, it is not too easy.

"What is scarce in East Vietnam?" Li Shimin frowned and asked, after all, everything is inseparable from a sharp word.

If Datang can come up with something that makes Dongyue happy, the other party will be willing to trade.

At this time, Dongyue actually occupied the Jiangnan region, which has been the land of fish and rice since ancient times, with abundant products and a pleasant climate.

In terms of the natural conditions of a single round, it is not better than Datang.

It was Dou Lukuan who replied: "If you go to Dongyue, iron should be the most scarce!" ”
