Datang: Li Shimin begged me to rebel

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

Or do you have something to say?A golden nest and a silver nest are not as good as your own kennel, but your own home is more comfortable.

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

"Your Highness, how is the strength?" Li Changge asked softly. Now it is not Yang Anning who massaged Li Ke, but Li Changge. Speaking of which, Li Ke only knew that this girl can actually massage Chinese medicine. It is the system. The kind who have studied the eight classics.

This is a good thing. In my previous life, it cost more than 200 yuan to go to the hospital for ten minutes.

"Not bad." Li Ke nodded in satisfaction, Yang Li squatted beside Li Ke and pinched his legs, and Yang Anning pinched Li Ke's feet.

Liu Qingchan played the piano beside her.

"Tian Meng, please report." Li Ke closed his eyes and said.

"Yes, Your Highness, all the seeds you gave me have been successfully planted." Tian Meng said with some excitement.

"All?" Li Ke suddenly opened his eyes.

"All." Tian Meng nodded fiercely, "However, the yield of some crops is not high, but we have reserved seeds for all of them, and if they are planted in some relatively fertile land next year, there should be no problem.

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

"Your Highness, we planted two acres of potatoes in total. I had someone carefully fertilize them, and then take care of them according to the potato breeding manual you provided us. The yield is beyond our imagination. Would you like to guess, Your Highness?" What?" Tian Meng was rarely mischievous, obviously he was also very emotional.

"Guess? Is there 5000 catties?" Li Ke asked with a smile, do you still want to shock me with this?The production of potatoes in later generations is beyond your imagination.

"Ah... can it be so high?" Tian Meng was stunned for a moment, and then said a little embarrassedly, "No, we harvested two acres of land, one mu of land is 2980 catties, and the other one mu of land is 3022 catties!"

Li Ke calculated in his mind that the yield per mu of potatoes in future generations can reach more than 8000 catties in areas dedicated to planting potatoes, but that requires high-yield potatoes, and areas dedicated to planting potatoes, chemical fertilizers, etc., if planted normally, it is about 5000 catties about.

If it is five thousand catties, the average is about 7.5 catties per square meter.

What Tian Meng and the others planted is 3000 catties per mu, but one mu of land in Datang is only 540 square meters, about 5.5 catties.But a catty of Datang actually has about 596 grams, which means that a catty of Datang is more than a catty of modern times.

Calculated in this way, Tian Meng's cultivation is equivalent to 6.6 catties per square meter.

The difference is not that big!

Obviously, the original seeds of the potatoes in the cafeteria were also seeds with extremely high yields. This Li Ke knows, because the potatoes purchased in the cafeteria are relatively large, and some are even as big as a child's head. Relatively high yield.

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

"Yes, Your Highness! It is equivalent to more than ten times that of other grains!" 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 sub-field, but this sub-field is A production of 400 catties has been hit!"

A subdivision of land is one-tenth of an acre, and the yield per mu is more than 4000 catties, which is obviously higher than that of potatoes.

In fact, there is not much difference in the output of potatoes and sweet potatoes, but what makes potatoes better than sweet potatoes is that people can live by eating potatoes alone, but not by eating sweet potatoes alone.

Sweet potatoes can only temporarily fill the stomach.

"Both sweet potatoes and potatoes are cultivated, but sweet potatoes can't be eaten for a long time, but potatoes don't have this problem. Has the detoxification method I entrusted to you dealt with it?" Li Ke asked.

Tuber-propagating crops such as sweet potatoes and potatoes are asexually propagated, so if they reproduce multiple times, the probability of pests and diseases will double, so they must be detoxified.

Many people have misconceptions, thinking that detoxification means that potatoes and sweet potatoes are poisonous. In fact, this is not the meaning. Potatoes are indeed weakly toxic, but it is mainly reflected in the fact that they are green, and sprouted potatoes cannot be eaten.

In fact, Li Ke was in the countryside when he was a child in his previous life. When the spring came, almost all the potatoes stored in the winter would germinate.Everyone used a plane to pick off the germination, cut off the green part with a knife and continued to eat, but no one was poisoned to death.

When I was a child, I saw that eating potatoes poisoned people to death. In fact, it was not only the toxicity of potatoes, but also eating foods that were in direct conflict with the toxicity of potatoes, which led to tragic results.

But in fact, the so-called potato and sweet potato detoxification refers to the way that removing potato and sweet potato tuber propagation will lead to a sharp increase in pests and diseases.

The potato breeding manual that Li Ke took out contains it. I have to say, the country is awesome!There are all these things in that library, and the stocks in this library are all dry goods!Anyway, Li Ke didn't see some useless books, and he couldn't find any music.

As for this kind of agricultural technology, there are the most technical books related to various crops, and the explanations are very detailed, ranging from simple to advanced.

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

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

But in fact, can potatoes be grown without detoxification?Can grow!Potatoes that are not detoxified will reduce the yield, but in fact, the yield of detoxified potatoes is about 30% to 50% higher than that of non-detoxified potatoes.

That is, the non-detoxification can produce 2000 jin per mu, and the detoxification can produce 3000 jin per mu.

The question is, do you think 2000 Jin is a magic weapon in Datang? !This is still an artifact!

What Li Ke and the others can play is the temperature-changing detoxification method.

"Your Highness, the masters in charge of agricultural matters said that they plan to use [-]% of the potatoes to continue planting next year, and the remaining [-]% ​​will be divided into [-] parts for detoxification according to the variable temperature detoxification method your Highness mentioned. poison, and then compare the planting, the main masters consider that it is their first time to operate, and they need to be skilled in the operation." Tian Meng said.

"Oh, that's a good idea. Who is the master in charge of agriculture?" Li Ke asked curiously.
