(1st Update)

"Isn't the land where food is grown growing vegetables? Aren't you hungry? Besides, the vegetable output is large, and the food will be saved in the coming and going. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info "Jin Yu didn't have a score in his heart, the vegetable production in this year was really not good, and the yield of ancient crops was low, so it was decided that the Tang people could only encourage the cultivation of grain and avoid vegetables from occupying the space of fertile land.

Li Chengqian was not very satisfied with Jin Yu's explanation, the half-grown child frowned, he could understand what Jin Yu said about the conversion between oil and water and grain, but he couldn't understand it when it came to the yield. "What Dr. Jin said is that Gu Neng understands, but growing vegetables takes up too much fertile land."

Jin Yu sighed helplessly, Li Chengqian was right, he also knew, but the output couldn't be raised, what could he do? As far as the eye could see, Yang Ying dug up a pond of lotus vegetables in early spring, which was brought from Li Daozong, the king of Rencheng, and later Jin Yu assigned someone to stock some fish so that he could add a dish to his table. Looking at the pond on the head of the village, Jin Yu realized, patted his forehead, and said: "Actually, there is another way, there is always a wasteland where you can't grow food, right?" A lot of words are idle, and they are idle, so what about planting lotus vegetables? ”

"Oh? That's a good idea. Li Chengqian nodded in response.

"You see, opening a pond can not only grow lotus vegetables, but also raise fish or something in it, which can replace food. If this production increases, a lot of food can be saved. "Three-dimensional farming, I learned it in junior high school textbooks, but I don't know how to take care of Jinyu, but I can hire a few people to watch it.

"It's doable." Li Chengqian's eyes lit up, but then he said worriedly: "Just these words, they can't play a big role, right?" After all, there are only a few places where many words can be turned into lotus vegetable ponds. ”

"The only way to do that is to breed good seeds and increase the yield of vegetables." Jin Yu said helplessly, manpower is sometimes poor, Jin Yu feels like this now. Jin Yu is a good food, he has a Zhuangzi in the mountains, and it is not much of a problem for the couple to eat a green vegetable or something, but it is far from enough to open a restaurant. This year, the popularity rate of radish is high, and when this winter comes, the common people will nibble on a radish pickle, and Jin Yu has always stayed away from radishes, because the ventilation effect of this thing is too strong''''''

"Cultivating good seeds? This method has been done by Sinong Temple, but it has not had much effect. Li Chengqian shook his head with a wry smile.

"How is that possible?" Jin Yu obviously didn't believe what Li Chengqian said, there were more good seeds in later generations, most of them were cultivated in just ten years, if it was said that it could not be cultivated, it could only be said that the method was wrong.

"Sinong Temple has indeed been cultivating good seeds, but the increase in yield is very limited, which is the reason why my father restricted farmers from growing vegetables." Li Chengqian's tone was very helpless, but his tone was categorical. It is because the grain production cannot go up, so Jinyu has sweet potatoes here that he has received so much attention.

"Is it the wrong way? Have you ever tried crossbreeding? Jin Yu asked tentatively.

"Hybridization? What is hybridization? After all, Li Chengqian was still a child, and he was more interested in new things, and when he heard a new term, he asked curiously.

"Well'''''' Jin Yu hesitated, isn't it too evil to talk about hybridization with a child who doesn't have any hair?

"Oh, the student lost his words." Li Chengqian looked at Jin Yu's hesitant face, thinking that he had asked some exclusive know-how, so he obediently confessed his mistake.

"It's just that you're too young, and it's better to not know some things." Jin Yu waved his hand, so that Li Chengqian didn't have to care.

"Lone is no longer a child, and Lone has passed the gift of a weak crown." Li Chengqian's attitude was a little excited, and he stood up and argued with Jin Yu. Li Chengqian hates to be seen as a child, but it is inconvenient for him to attack Jin Yu.

"Hehe, Cheng, then tell you." Jin Yu patted the grass next to him and asked Li Chengqian to sit down, anyway, when he was in junior high school, he was not a few years older than Li Chengqian, and now the child is precocious, and it is not a big problem to talk about it. "The so-called hybridization is the birth of new species between different species." …,

"Huh?" Li Chengqian blushed a little, he didn't expect Jin Yu to tell him this, he had a few albums hidden in private, which depicted people and animals'''''' fortunately he didn't try it, wouldn't it be a shame to have any new species in that way?

"People are not big, they have a lot of thoughts" Jin Yu understood everything as soon as he saw Li Chengqian's appearance, it seems that people have been in contact, but they don't use the right place, "It's not good between people and animals, animals and animals, plants and plants are okay." ”

was broken by Jin Yu's words, Li Chengqian was a little embarrassed, and arched his hand in embarrassment, signaling Jin Yu to continue.

"Have you seen that horse and donkey beast of the Wing Kingdom Prince? A lot of words," Jin Yu asked, Li Chengqian. To say that this horse and donkey beast is the name given by Qin Qiong, to put it bluntly, it is a mule in later generations. The importance of the mule was not yet realized in those years, and it was the evidence of the crime left by the drunken horse who ran into the donkey pen and committed a terrible atrocity against the female donkeys.

"Well, yes. That's what Dr. Jin said about the new species produced by hybridization? Li Chengqian's face was better, mules appeared as early as the Spring and Autumn Period and the Warring States Period, but they were not used in farming, but as an object to show off among nobles.

"Well, that's it, it's just that the horse and donkey beast of the Wing Kingdom Mansion is useless, and can only be used for viewing. If it is a cross to produce donkeys, horses and beasts, it will be of great use. Our hometown calls it 'mule', which has the weight-bearing capacity and resistance of a donkey, the flexibility and running ability of a horse, eats less than a horse, has more strength than a horse, and belongs to a kind of raw and capable livestock. In our hometown, we all use mules for farm work, but we can't have children. Jin Yu didn't lie, in the countryside in later generations, many farmers were using mules, with a long life span and great strength, which belonged to the category that was very useful.

"How can there be such an animal?" Li Chengqian's eyes lit up and he was excited. Now the rich farmers use oxen, those who don't have money use donkeys, and the poorest can only use manpower. Donkeys are cheap, but their strength is not as big as that of cattle, if it is really as Jin Yu said, those mares who can still give birth after retirement can still exert their residual heat and benefit the people of Datang.

"Wouldn't you know if you tried it? Can I still lie to you? Jin Yu dragged a horsetail grass and put it in his mouth, it was a little tender, and he spit it out after lying on the ground.

"I'll try it when I go back." Li Chengqian said eagerly.

"Mules work quickly, and it doesn't take a year to prove, but the dishes are different, and it often takes several generations of hybridization between different vegetables to have mutations." Speaking of food, Jin Yu has a headache, he misses the cabbage dumplings in the future. I remember that in winter, when he went to the kitchen to ask Xue Niang if she had any cabbage, Xue Niang pointed to a dry little cabbage at the root of the wall and said that this is cabbage''''''

In later generations, Chinese cabbage, which cost a dime and a pound, could not be bought with money in the current Chang'an, because cabbage had not been cultivated at this time, but the hateful thing is that the textbook actually said that China had it during the Warring States Period, isn't this misleading? I already knew that I would bring some cabbage seeds'''''' for the sake of his stomach, Jin Yu decided to teach the concept of "hybridization" to Li Chengqian, maybe he could eat the familiar cabbage dumplings a few years in advance.

"Vegetables can also be hybridized?" Li Chengqian was even more surprised when he heard this, he could understand among the animals, after all, what organs are there, but the plants ''''''

"Look down on vegetables or what's the matter? Vegetables are also male and female, but some are monoecious, and some are dioecious. Jin Yu turned sideways, grabbed a wildflower, handed it to Li Chengqian, and spoke.

Li Chengqian felt that he was really eye-opening, but he didn't expect that there was so much knowledge about plants''''''

"The hybridization between plants is much more complicated than that of animals, and it is more important to try between various dishes. Animals, donkeys and mares have become, and the rest is a successful crossbreeding, and it's just a dish, not much use. Jin Yu gave Li Chengqian a golden finger and instructed him. …,

"Students, remember Dr. Jin's teachings," Li Chengqian stood up and saluted respectfully to Jin Yu, who was lying on the ground. He understands very well that the value of these things that Jin Yu said has a great effect on improving the lives of farmers, after all, there is no mechanical power transportation at this time, and the land basically relies on cattle, horses, and donkeys.

"What is not taught, then pay more attention to the matter of vegetable hybridization, I still hope to taste fresh vegetables as soon as possible." Jin Yu sat up and stretched back.

"Hmm." Li Chengqian nodded and agreed, he was young, and he was not as affordable as Empress Changsun, and asked hesitantly: "Dr. Jin, can't the method of raising pigs really not be promoted?" ”

"It's enough for the time being, why don't you walk around Zhuangzi more, see more, and get to know each other?" It is true that Jin Yu threw out the method of hybridization with his own selfishness, but he also wanted Li Chengqian to have something to do, after all, there is no very profound knowledge in planting sweet potatoes, and a dignified prince is busy in his study or in the field, and it is strange that he is in a panic, since now Li Chengqian feels that hybridization alone is not enough, then add more workload to him.

"Cheng, thank you Dr. Jin." Li Chengqian was overjoyed, and finally completed half of the task assigned by Empress Changsun.

"You're so polite." Jin Yu stood up, suddenly remembered something, and asked Li Chengqian: "Do Guo Yu and Zhang Peng have any special background?" ”

"Special background?" Li Chengqian frowned and thought for a while, and said without concealment: "Guo Yu is the twenty-eighth grandson of Guo Jia, the sacrificial wine of the Air Force and the Marquis of Weiyang, right?" A lot of words Zhang Peng is a small official, no background. ”

"Oh, that's good." Jin Yu nodded, Guo Jia, the characters of the Three Kingdoms period, no matter how bullish the fork is, it can't affect the Tang Dynasty, right? A lot of words seem to be arranged by Li Erting, looking for two people who are not big names to learn from him. I still like this kind of thing, and next time Li Er comes to his private visit to this micro-service, he must entertain him with good wine and food
