"Potato, sweet potato?" Gu Yanwu lowered his head and pondered for a moment, and then sighed, "The names of these two overseas good breeds Yan Wu has also heard a little, if this is as productive as Liu Zongbing said, once it can be promoted in the Central Plains, it will be a solution." Pen | fun | pavilion www. ｂｉｑｕｇｅ。 Although info is only a symptom but not a cure, it is indeed the most urgent need for the people of the Central Plains! After Yanwu's question is asked, please ask Mr. Liu to ask the question! ”

Liu Fan smiled and said, "Okay, then the governor will also ask Mr. Gu a question!" Jiangnan is the land of fish and rice, the textile industry is also famous all over the world, and sericulture has been one of the fundamentals of the survival of the people in Jiangnan since ancient times. I heard that Mr. Gu is from Kunshan, so you must know the situation in Jiangnan well? Then the governor wanted to ask Mr. Gu if there was a way to help the people of Jiangnan solve the sericulture problem that plagued them and increase the output of grain? ”

Gu Yanwu glanced at Liu Fan in astonishment, thought for a moment and said, "The matter of agriculture and mulberry is an extremely important thing for the entire Jiangnan, and it has been a matter of concern to people since ancient times. Yan Wu has been researching for many years and has found that only extensive planting of mulberry trees and silkworm breeding can increase production. As for farming, only intensive cultivation and more fertilization can have a bumper harvest! Gu Yanwu's tone was a little uncertain, he still knew a lot about farming, but Liu Fan asked about ways to increase production, which made him a little blind, so he could only summarize it according to the experience of his predecessors and his own experience.

Liu Fan also saw Gu Yanwu's lack of confidence, shook his head and smiled, "Mr. Gu's methods are just clichés, and what this governor is asking now is a specific solution, not a solution." ”

Gu Yanwu smiled bitterly, shook his head helplessly, and said, "Although Yanwu knows some agricultural matters, he is not very proficient, and he knows nothing about the method of increasing production. Yan Wucai is a shallow learner and is willing to admit defeat! ”

Seeing this, Liu Fan was quite happy to hug his fists and said, "Mr. Gu has conceded!" In fact, Mr. Gu doesn't have to be discouraged, he has a specialization in the art industry, what you are good at is not farming after all, and it is normal that you can't answer. ”

Gu Yanwu said gloomily, "If you lose, you lose, Gu claims to be erudite and talented, and he has always been proud of it." Today, after Liu Zongbing's questioning, I realized my own shallowness. There are people outside the world, there are people outside the world, Gu Mou looks down on the people in the world too much! ”

Gu Yanwu was about to turn around and step down, when a voice suddenly sounded in the crowd and said, "Although Mr. Gu can't answer, Mr. Liu may not know!" If Liu Zongbing, as the person who made the question, still doesn't know, this winning method is a little disgraceful! ”

When everyone heard the prestige, they saw that Zhang Pu, the leader of the Restoration Society, had already stood under the stage at some point, and it was he who asked questions. Hearing Zhang Pu's question, everyone was also puzzled, and even Gu Yanwu stopped and looked at Liu Fan with an inquiring face.

Seeing this, Liu Fan said frankly, "Since this governor dares to ask, there is naturally a way to answer!" Since you all have doubts, then Bendu will convince you to lose! The Governor also carefully studied the production and farming mode in the south of the Yangtze River, and after several thoughts, he came up with a method, which the Governor called the 'rice and fish farming method'! ”

"As the name suggests...", Liu Fan briefly described the rice field fish farming method that was widely spread in later generations to everyone. Finally, it was concluded that "using the water surface of the rice field to raise fish can not only obtain fish products, but also use fish to eat pests and weeds in the rice field, excrete manure, turn the soil to promote fertilizer decomposition, create good conditions for rice growth, and greatly increase the yield of rice!" Does Mr. Gu think the Governor's approach is feasible? ”

Gu Yanwu sighed, "Mr. Liu's talent is a hundred times better than Gu's, and Gu is convinced." It's just that since Mr. Liu has such a good strategy, why didn't he come up with it earlier to benefit the world!? ”

Liu Fan touched his nose a little embarrassed, he couldn't say that this method that was widely spread in later generations was something he "just thought of"! If anyone believes it! You must know that rice and fish farming is easy to say, but it is indeed the experience of Chinese farmers who have explored it for hundreds of years, and it is impossible to do it without a deep understanding of agricultural affairs.

After being silent for a while, Liu Fan said embarrassedly: "That, Mr. Gu also knows that Liu was born in the north and has never been to Jiangnan, and this method was also thought of after I arrived in Jiangnan." Liu traveled all the way from Hangzhou to Nanjing and saw the rice planting methods of the people in the south of the Yangtze River, so he had a whim and thought of raising fish in the rice fields. After many verifications, this method of rice and fish farming was obtained. ”

Liu Fan's explanation was also quite reasonable, and everyone nodded in acceptance when they heard this. After Gu Yanwu listened, he bowed down to Liu Fan and said, "Mr. Liu's genius, Gu admires him very much!" Yanwu on behalf of millions of people in the south of the Yangtze River, thank you Liu Zongbing for your great kindness! After that, he bowed down to Liu Fan deeply.

Liu Fan was shocked, and hurriedly took two steps forward to help Gu Yanwu up and said, "Mr. Gu doesn't have to be like this, even if you don't ask, Liu Fan will hand it over to Lord Lu in a few days." You made this great gift, Liu Fan felt deserved! Hurry up, please! ”

Gu Yanwu praised again and again when he heard this, and gave great affirmation to Liu Fan's character and talent, and bluntly said that he would visit him another day to discuss agricultural affairs in Jiangnan. Seeing that the two actually made a friendship, Zhang Pu, the initiator in the audience, was almost blackened into a pot of charcoal. had to cough heavily a few times to remind Gu Yanwu not to forget his identity.

After Gu Yanwu was defeated and stepped down, another person came to the stage to challenge Liu Fan, and this person was Huang Zongxi, who was as famous as Gu Yanwu. Unlike Gu Yanwu, who is more proficient in agriculture, Huang Zongxi is better at astronomy and geography in addition to poetry and articles. Therefore, he chose to challenge Liu Fan with the method of arithmetic, which is often used in astronomy.

The arithmetic test is relatively simple, only one person needs to answer the question, and two people answer it separately, so it is easy to distinguish the winner and loser. So this time, I invited Lu Weiqi, the secretary of the military department, as the author of the question.

After the two of them were ready, Lu Weiqi stood in front of the two of them and said, "There are three people today, one in three, one in six cents, one in three, and three in four." Ask people how much they have? ”

"......" Liu Fan glanced at Huang Zongxi, who was scheming, speechlessly, and suddenly sighed, three people, one of three people, well, three and a third? (I can't show the formula here in the background, and I can't help it, so I have to skip these formulas) pick up a brush and sketch a few strokes on the rice paper. In less than a minute, Liu Fan quickly replied, "2 and 8 cents!" Oh, it's two dollars and one-eighth of a dollar! ”

Lu Weiqi glanced at Liu Fan in surprise, and said silently, "The answer is correct!" In this round, Mr. Liu won! Then he glanced at Huang Zongxi a little helplessly, and continued to ask, "The existing Fang Tian is four-sevenths wide and three-fifths long. Q: What is the area of this field? ”

"Twelve steps out of thirty-five!" After a few breaths, Liu Fan gave the answer again

Lu Weiqi, who did not give up, asked a few more questions one after another, but before Huang Zongxi could react, Liu Fan calculated the answer at a very fast speed. One or two questions can be said to be a fluke. But after answering so many questions, Huang Zongxi could only admire.

Huang Zongxi sighed faintly, stopped Lu Weiqi's next question, and said directly to Liu Fan, "Mr. Liu is a great soldier, Huang is not as good as sighing!" Throw in the towel under it! (To be continued.) )
