In the evening, there was a shopping mall, where a room was reserved for Li Ke, and after dinner, Li Ke lay on his recliner and breathed a sigh of relief.

Or is there something good to say? The gold and silver nests are not as good as their own kennels, but they are still comfortable at home.

There is an inexplicable sense of comfort when I return home.

"Your Highness, how is the strength?" Li Changge asked softly, now it is not Yang Anning who massages Li Ke, but Li Changge, speaking of which, Li Ke also knows that this girl can actually know how to massage in traditional Chinese medicine, which is the kind that has systematically learned the Eight Classics.

This is a good thing, it took more than 200 minutes to go to the hospital in my last life.

"Not bad." Li Ke nodded with satisfaction, Yang Li squatted beside Li Ke to pinch his legs, and Yang Anning was pinching Li Ke's feet.

Liu Qingcicada was stroking the piano next to him.

"Tian Meng, report it." Li Ke closed his eyes and spoke.

"Yes, Your Highness, all the seeds you gave me have been successfully planted." Tian Meng said in a somewhat excited tone.

"All?" Li Ke opened his eyes suddenly.

"All." Tian Meng nodded violently, "However, the yield of some crops is not high, but we have all reserved seeds, and if we plant them in some more fertile land next year, there should be no problem."

"How are potatoes and sweet potatoes growing?" Li Ke looked at Tian Meng and asked, Li Ke left only a little bit of the potatoes in the kitchen, and almost all the rest were handed over to Tian Meng to plant, and the same is true for sweet potatoes, but the number of sweet potatoes is not much, and the skin is damaged, and Li Ke doesn't know if it can grow.

"Your Highness, we have planted a total of two acres of potatoes, and I have people carefully apply fertilizer, and then take care of the potato cultivation manual you provided to us, and produce the yield...... It's beyond our imagination, would you like to guess, Your Highness? Tian Meng was rarely naughty, obviously his emotions were also very excited.

"Guess? Is there 5000 pounds? Li Ke asked with a smile, do you still want to use this to shock me? In later generations, the yield of potatoes is beyond your imagination.

"Ah...... Can it be that high? Tian Meng was stunned for a moment, and then said with some embarrassment, "No, the two acres of land we harvested, one acre of land is 2,980 catties, and the other acre of land is 3,022 catties!" ”

Li Ke converted it in his mind, the yield per mu of potatoes in later generations, the area specializing in planting potatoes can reach more than 8,000 catties, but that requires high-yield potatoes, and areas that need to specialize in planting potatoes, chemical fertilizers, etc., if planted normally, it is about 5,000 catties.

If it is 5,000 catties, the average per square meter is about 7.5 catties.

Tian Meng and they planted a yield of 3,000 catties per mu, but Datang only has 540 square meters per acre, about 5.5 catties. But Datang one pound actually has about 596 grams, that is, Datang one pound is more than a modern one.

In this way, Tianmeng is equivalent to 6.6 catties per square meter.

That's not a big difference!

Obviously, the original seeds of those potatoes in the canteen are also extremely high-yield seeds, and this Li Ke knows that because the potatoes purchased in the canteen are relatively large, and some are even as big as a child's head, this kind of potato is relatively high-yielding.

"That's the yield of 25 stones per mu." Li Ke took a deep breath, what is an artifact? This is the artifact!

"Yes, Your Highness! That's more than ten times as much as any other grain! Tian Meng said excitedly, "And the yield of sweet potatoes is higher, Your Highness, the sweet potatoes you gave us are only enough to plant one piece of land, but this point of land has a yield of 400 catties!" ”

One cent of land is one-tenth of an acre, and the yield per mu is more than 4,000 catties, which is obviously higher than that of potatoes.

In fact, there is not much difference between the yield of potatoes and sweet potatoes, but the difference between potatoes and sweet potatoes is that people can live just by eating potatoes, but not by eating sweet potatoes alone.

Sweet potatoes can only fill the stomach temporarily.

"Sweet potatoes and potatoes are cultivated, but sweet potato people can't eat them for a long time, but potatoes don't have this problem, have I dealt with the detoxification method I handed over to you?" Li Ke asked.

Sweet potatoes and potatoes are propagated by tubers because they reproduce asexually, so if they are propagated multiple times, the probability of pests and diseases will double, so they must be detoxified.

Many people have a misunderstanding, thinking that detoxification is that potatoes and sweet potatoes are poisonous, but in fact, this is not the meaning, potatoes are indeed weakly toxic, but it is mainly reflected in the green, sprouted potatoes are not edible.

In fact, in his previous life, Li Ke was in the countryside when he was a child, and when it came to the beginning of spring, almost all the potatoes stored in the winter would sprout, and there was nothing that did not sprout, but I didn't see any household throwing them away. Everyone used a planer to cut off the germinated part, cut the blue part with a knife and continued to eat, and no one was poisoned.

When I was a child, I saw eating potatoes to poison people, in fact, it was not only the toxicity of potatoes, but also eating food that was exactly the same as potato toxicity that led to the tragic result.

But in reality, the so-called detoxification of potatoes and sweet potatoes refers to the way in which the removal of potatoes and sweet potato tubers leads to a sharp increase in pests and diseases.

The potato breeding manual that Li Ke took out is there, and I have to say that the country is awesome! These things are all in the library, and the stocks in this library are all dry goods! Anyway, Li Ke didn't see some useless books, any music or the like, he didn't find them anyway.

For example, there are the most books on various crop-related technologies such as this agricultural technology, and the explanations are very detailed, ranging from simple to advanced.

Take potato detoxification as an example, there is the simplest, variable temperature detoxification method, which is to keep the potatoes in a room at a temperature of 40 degrees for a certain time, and then lower to a room at a temperature of 20 degrees for a certain period of time, through this temperature change to kill several diseases in the potatoes.

The other is through the bud tip detoxification method, but that thing is too high-end, and the current Datang can't play it.

But in fact, can potatoes be grown without detoxification? I can plant! Potatoes that are not detoxified will reduce yields, but in fact, detoxified potatoes increase yields by about 30 to 50 percent compared to non-detoxification.

That is, the yield per mu without detoxification is 2,000 catties, and the detoxification can yield 3,000 catties per mu.

The question is, do you say that 2,000 catties is an artifact in Datang?! It's still an artifact!

Li Ke: What they can play is the temperature change detoxification method.

"Your Highness, several masters in charge of agricultural matters said that they are going to use eighty percent of the potatoes directly for planting next year, and the remaining twenty percent will be divided into fifty parts for separate detoxification according to what Your Highness said about the variable temperature detoxification method, and then compare the planting, the main masters consider that they are the first time to operate, and they need to carry out skilled operations." Tian Meng said.

"Oh, that's a good idea, who is the master in charge of agriculture?" Li Ke asked with some curiosity.
