In fact, it was Xiao Mu's decision to ask Xu Guangqi about the sweet potato trial planting, and the original purpose was not to really care about this cause - although this sweet potato trial planting is indeed very useful to the Ming Dynasty, which is currently suffering from a great drought, and Xiao Mu also knows this, but at this moment, Xiao Mu really has to admit that the main purpose of looking for Xu Guangqi is not really out of the importance of sweet potato planting, but in fact, it is to get rid of the embarrassment of threatening to invent the telephone in front of Lin Yi.

But now Xu Guangqi has come in a hurry, and he doesn't know what to say after asking about the situation in general, which is obviously a sign of extreme disrespect for Xu Guangqi, a famous scientist.

Even Xiao Mu had the illusion that his behavior was simply a copy of the "Beacon Opera Princes" - also for the sake of a woman, let the courtiers below run over in vain, but only to tell him that there was nothing to do. Xiao Mu felt that if he told Xu Guangqi the real situation, he was afraid that this old minister would even be in danger of fainting directly.

However, there is still an essential difference between today's incident and the "Beacon Opera Princes", that is, this matter should have nothing to do with Lin Yi himself, all because Xiao Mu said the words "funny coins", and later in order to divert Lin Ye's attention, he had to find Xu Guangqi to come over - of course, in the allusion of "The Princes of the Beacon Theater", the black cauldron should not be carried by the famous beauty, after all, people just don't like to laugh, and other things like taking the beacon tower to light and play are the masterpieces of the mentally handicapped King Zhou You.

And compared with the "Beacon Opera Princes", the current situation will not have any serious consequences, after all, it is only Xu Guangqi who has come alone, not a large number of troops, there is no problem of labor and salary, and it has not hurt Xu Guangqi's feelings for the time being-as long as Xiao Mu can find something to talk about immediately.

So now, Xiao Mu couldn't care so much, so he had to control his nervous thoughts about wiping his sweat, and asked: "I heard that sweet potatoes are very peculiar, and there is nothing to eat on potato vines, on the contrary, what can be used for human consumption after maturity is actually the part buried in the ground, I don't know if this is the case?" ”

Xiao Mu pretended not to know and asked a question that all three people present knew well, trying to delay time in this way so that he could think of a topic that he really needed to communicate with Xu Guangqi. When asking, Xiao Mu repeatedly chanted the mantra "You don't know" to himself in his heart, and finally successfully completed self-hypnosis, so this sentence does sound very realistic, even Lin Yi, who was listening to it on the side, seemed to feel that Xiao Mu really didn't know about this problem.

"Xiao Mu, who is mentally retarded, doesn't he even know that the essence of sweet potatoes is underground roots, and this kind of knowledge that elementary school students have learned to dig out of the soil?" -- This is the true thought in Lin Ye's heart at this time, which also proves how realistically Xiao Mu's question is.

But Xu Guangqi didn't know that the emperor and the queen actually knew all about this problem, and replied seriously: "Back to the emperor, that's exactly the case, although the potato vine and the leaves themselves are also edible, but the rattan itself is more like a vegetable than a staple food, and it really has the value of large-scale promotion and planting, and it can be used as food for the people to eat or the underground root part." ”

Fortunately, Xiao Mu was still a little quick to be wise - Xiao Mu found that he was indeed very talented in the face of crisis, and after successfully delaying for a while with the question he knowingly asked, he finally thought of something that he thought was very important for sweet potato cultivation and that he also thought was very necessary to tell Xu Guangqi. So Xiao Mu didn't continue to ask those low-IQ questions, but said: "I heard that sweet potatoes will sprout after being left for a long time, I wonder if I can bury the sprouted sweet potatoes directly in the soil, and then wait for them to grow, and finally until they mature, and produce more sweet potatoes?" ”

This method is undoubtedly feasible, Xiao Mu recalled the education he received in middle school, this breeding method should belong to the category of "asexual reproduction", and the traits of the potato vines that grow at the end will not change in any way, which can completely ensure the stability of the variety, so you only need to find a high-yield variety, and then you can plant a large number of them through this asexual reproduction.

In particular, this way of burying sweet potatoes that could have been eaten directly into the ground is to grow more sweet potatoes for human consumption, which gives Xiao Mu a feeling of burying money in the soil and then waiting for the autumn to harvest more money. In fact, the reason why Xiao Mu had such an idea was that he felt that the sprouted sweet potato that could be used for propagation must be a small piece, unlike other crops, where the seeds were all small grains.

Of course, other crops are also like this, as the seeds buried in the soil to brew a bumper harvest, in fact, for farmers are real food that can be eaten, but in Xiao Mu's later generations, agricultural seeds are directly bought from breeding companies, and no farmers will keep the seeds of the next year.

Xu Guangqi's heart was full of shock at this time, because the sweet potato crop is still a new thing in the Ming Dynasty, especially in the north, almost no one has planted it, let alone seen or eaten it, but the emperor can say a major feature of sweet potato in this case, which shows that the emperor has done enough homework on the sweet potato crop on weekdays, and must have spent a lot of time and energy to understand.

Xu Guangqi replied: "Back to the emperor, it is true, the sweet potato itself will sprout at the right temperature, and although the sprouted sweet potato is still edible, the effect is not as good as before. A sweet potato often produces multiple shoots, and multiple potato vines can be obtained by cutting the sweet potato into small pieces and burying them in the ground. The minister plans to find suitable potato seeds for cultivation in the north first, and then use this method to quickly expand the scale. ”

Xu Guangqi patiently explained for the emperor, and thought with relief in his heart: "The emperor must have already read through the "Uncle Gan" I submitted before, otherwise, how could he know so much about sweet potatoes?" ”

Xiao Mu listened to Xu Guangqi's answer, and knew in his heart that he had thought too much, "Sweet potatoes will sprout after a long time, and then bury them in the soil to grow new sweet potatoes, this kind of most basic thing, as a great scientist who can write "Sweet Potato Shu", how can he not know it?" ”
