"This ......" Seeing the sweet potatoes and corn that Liu Chan took out, Li Hui was stunned for a moment.

What is this?

That's what I just ate?

Why haven't I seen this grain before?

Three doubts.

Liu Chan pointed to sweet potatoes and corn and introduced: "These two things are called sweet potatoes and corn, they are high-yield grains, as for the taste, you have also tasted it, now I still have a lot of seeds here, May is the sowing season, I want you to send these things to Chengdu, ask my father to let people sow seeds." ”

Li Hui was puzzled: "Shizi, where did this thing come from?" Since you found it, wouldn't it be better for you to send someone to give it to the lord! ”

Liu Chan shook his head and said, "Have you forgotten how you promised just now, if I can tell me the way, why do I need to ask you to send someone to my father?" When you sent someone to give it to your father, you said that you found it by the barbarian tribe near Pingyi County, and that I had already written down the method of preserving these seeds and the method of sowing them, so that you could copy a copy of them yourself, so that your father would not see that it was my handwriting. ”

Liu Chan said, taking out a folded paper from his arms.

Li Hui took the paper, there were four or five sheets of paper, densely recording the preservation methods of sweet potatoes and corn seeds, as well as the methods of sowing, and even many details.

Li Hui took a cursory look, but was shocked by a place in the paper: "Shizi, the yield of this sweet potato per mu is actually 1,500 catties?" There are actually 400 catties of corn? How is this possible? ”

Han is only more than 200 grams a catty, two catties are worth a catty in later generations, and the output written in this paper is several times less than the data of later generations.

Liu Chan knew that the high-yield data in later generations were obtained from mechanized planting, and the application of chemical fertilizers and pesticides would definitely not be able to achieve such a high yield when they were planted in the Three Kingdoms, so Liu Chan said a few times less.

However, despite this, the yield that Liu Chan said is much more than the current average grain yield of twenty or thirty catties per mu in the Han Dynasty.

Li Hui looked at the data that Liu Chan said, but instinctively didn't believe it.

First, it is sweet potatoes, and the origin of corn is unknown, and second, Li Hui does not believe that there can be such high-yield grain in this world.

"Just plant as I say, no more!" Liu Chan looked at Li Hui and said firmly.

Liu Chan was also a rural household in his previous life, and he was also clear about the planting methods of corn and sweet potatoes, and the content of the letters was extremely detailed.

Li Hui looked at it carefully, but he was even more suspicious, the planting of corn is nothing, this sweet potato is actually planted with vines? Can a vine survive if it is cut?

Li Hui was embarrassed: "Shizi, you said that if this kind of potato is planted, it can grow a large number of green vines, and the green vines can be cut and planted in the soil to live, how is this possible?" Although I am not proficient in farming, I also know that this plant cannot survive without roots, such a ridiculous thing, I am afraid that he will not believe it, if it cannot be planted, it is even more important! ”

According to Liu Chan, his seeds can be planted on the land of at least one county, and if he dedicates this kind of seed to Liu Bei and does not plant it, resulting in a county not harvesting this year, it is a big crime.

Now Li Hui has just served as the governor of Nanzhong, but he does not dare to take risks easily.

Hearing Li Hui's words, Liu Chan said with a smile: "It's not that there are no roots, but the roots are small. ”

Li Hui just looked at the paper Liu Chan gave him, silent, this thing was too novel, he didn't believe it at all.

Seeing Li Hui like this, Liu Chan secretly said in his heart: "It is so difficult for me to convince Li Hui, he will tell his father again, I am afraid that my father will not believe it, now my points are used to exchange for seeds, and I must plant it this year, if I don't plant it, it will be wasted."

However, these seeds do not have to be planted in Chengdu, I want my father to promote the cultivation of sweet potatoes and corn, but I want to be bad, since I came to Nanzhong, why send the seeds to Chengdu, let Li Hui plant in Nanzhong?

When it was time to harvest, when he invited his father to come and watch, he saw the finished product, and he would definitely agree to promote it on a large scale in Yizhou, and this sweet potato is not easy to preserve, and it is not convenient to send it to Chengdu. Even if my father agrees to plant in Chengdu, it may still be known by Xizuo! ”

Liu Chan paused and said: "This kind of seed can definitely grow food, you can rest assured of this, so let's let you give this kind of seed to your father is not convenient, why don't you grow it yourself in Nanzhong?" ”

"This ......"

Liu Chan said: "Nanzhong is vast and sparsely populated, and there are not many people in Pingyi County, you have 5,000 soldiers and horses in the Governor's Mansion, and now there is still some time before May, you can order the soldiers and horses to open up the wasteland and cultivate these two crops, and after planting them in the autumn, you will notify your father again not too late, if you don't plant them, there is no sin, what do you think?" ”

Li Hui didn't hesitate this time, nodded, and agreed: "That's very good!" ”

Liu Chan ordered: "This sweet potato seed must be cellared, please trouble you tonight, first order someone to put the sweet potato seeds into the cellar, and the corn seeds can be placed in a dry and ventilated place." ”

"I'll do it!" When Li Hui heard this, he gave up his orders, and the cellar was needed for winemaking, and the people also needed a cellar to store grain for the winter, so this cellar was not troublesome.

Since it was decided to plant corn and sweet potatoes in Nanzhong, Liu Chan did not rush to the land of the barbarians, but temporarily lived in Pingyi County.

Although Liu Chan told Li Hui the detailed planting method of sweet potatoes and corn, Liu Chan was still a little uneasy, after all, there were so many seeds, if Li Hui didn't plant them, next time he wanted to accumulate points to exchange for seeds, I don't know what year and month he would have to wait.

Therefore, Liu Chan wanted to personally guide Li Hui.

Li Hui led his troops to the south, and also eradicated many corrupt officials and powerful landlords, so a large amount of land was vacated, but there was no need for large-scale land reclamation.

Liu Chan took Li Hui and several agricultural officials in the county government to walk in the field and explained to them in detail the planting method: "The land where corn is planted can be three feet wide, and this width can be planted with two plants. If there are animal bones, they can be burned and crushed into the ashes, and if there are weeds, they should be cleaned up in time.

As for the sweet potato field, a single ridge two feet wide is sufficient, and the seed potatoes can be planted in the soil in late April, and the green vine cuttings can be collected in mid-May and early June......

By the way, this sweet potato, the corn beast likes to eat it very much, and all around it must be fenced with wooden stakes, and it is necessary to send someone to guard it to prevent the beast from destroying it. ”

The land of Nanzhong is different from the plains, which are hilly and mountainous, and these lands are reclaimed on the gentle slopes under the hills, and if they are wide plains, they are not afraid of wild beasts at all, but at the foot of this mountain, they are the most attractive to wild beasts.
