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 comfortable sigh of relief.
Or is there something nice to say? A golden nest or a silver nest is not as good as your own kennel, but your own home is more comfortable.
There is an inexplicable sense of comfort when I return home.
"Your Highness, how is the strength?" Li Changge asked softly. Now the person massaging Li Ke was not Yang Anning, but Li Changge. Speaking of which, Li Ke also knew that this girl could actually do Chinese massage. It was the system The kind who have studied the Eight Classics of Children.
This is a good thing. In my previous life, it cost more than 200 yuan to go to the hospital in ten minutes.
"Not bad." Li Ke nodded with satisfaction. Yang Li squatted next to Li Ke and squeezed his legs, while Yang Anning squeezed Li Ke's feet.
Liu Qingchan was playing the piano beside her.
"Tian Meng, please report." Li Ke said with his eyes closed.
"Yes, Your Highness, all the seeds you gave me were successfully planted." Tian Meng said with some excitement.
"All?" Li Ke suddenly opened his eyes.
"All." Tian Meng nodded sharply, "However, the yield of some crops is not high, but we have reserved seeds for all of them. If we plant them in some relatively fertile land next year, there should be no problem.
"How are the results of planting potatoes and sweet potatoes?" Li Ke looked at Tian Meng and asked. Li Ke left only a few potatoes in the kitchen, and almost all the rest was given to Tian Meng to plant. The same is true for sweet potatoes. , but there are not many sweet potatoes, and the skins are damaged. Li Ke doesn’t know if they can grow.
"Your Highness, we planted two acres of potatoes in total. I had people carefully apply fertilizers and then take care of them according to the potato cultivation manual you provided us. The yield... exceeded our imagination. Your Highness, would you like to guess? For a moment?" Tian Meng gave a rare naughty moment, and he was obviously very excited.
"Guess? Is it 5,000 pounds?" Li Ke asked with a smile, do you still want to shock me with this? The yield 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 with some embarrassment, "No, the two acres of land we harvested, one acre weighed 2,980 kilograms, and the other acre weighed 3,022 kilograms!"
Li Ke did some calculations in his mind. In later generations, the yield of potatoes per mu in areas dedicated to growing potatoes can reach more than 8,000 jins. However, that requires high-yielding potatoes, areas dedicated to growing potatoes, chemical fertilizers, etc. For normal planting, it is about 5,000 jins. about.
If it weighs five thousand kilograms, the average weight per square meter is about 7.5 kilograms.
What Tian Meng and the others grew was 3,000 kilograms per mu, but one acre of land in Datang was only 540 square meters, about 5.5 kilograms. But one catty of the Tang Dynasty actually weighed about 596 grams, which means one catty of the Tang Dynasty was more than one catty of modern times.
Calculated this way, Tian Meng and the others can produce an equivalent of 6.6 pounds per square meter.
This difference is not big anymore!
Obviously, the original seeds of the potatoes in the cafeteria were also very high-yielding seeds. Li Ke knew this, because the potatoes purchased in the cafeteria were relatively large, and some were even as big as a child's head. These potatoes were Relatively productive.
"That's an output of 25 stones per mu." Li Ke took a deep breath. What is an artifact? This is an 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 piece of land, but this piece of land is The output was 400 kilograms!”
One piece of land is one-tenth of an acre, and the yield per acre is more than 4,000 kilograms, which is obviously higher than potatoes.
In fact, there is not much difference in the yield between potatoes and sweet potatoes, but what makes potatoes better than sweet potatoes is that people can live just eating potatoes, but not just eating sweet potatoes.
Sweet potatoes can only fill your stomach temporarily.
"Both sweet potatoes and potatoes are cultivated, but people cannot eat sweet potatoes for a long time, but potatoes don't have this problem. Have you dealt with the detoxification method I gave you?" Li Ke asked.
Sweet potatoes and potatoes, which are tuber-propagated crops, reproduce asexually, so if they are reproduced multiple times, the probability of pests and diseases will double, so they must be detoxified.
Many people have a misunderstanding, thinking that detoxification means that potatoes and sweet potatoes are poisonous. In fact, this is not the case. Potatoes are indeed slightly toxic, but mainly in the form of green and sprouted potatoes. You cannot eat potatoes that have sprouted.
In fact, in his last life, when Li Ke was a child in the countryside, when spring came, almost all the potatoes stored over the winter would sprout. There were no potatoes that did not sprout, but I didn’t see any household throwing them away. Everyone used a plane to dig out the sprouted areas, and used a knife to cut off the green parts and continued to eat, but no one was found poisoned.
When I was a child, I saw people poisoning people by eating potatoes. In fact, it was not only the poison of potatoes, but also the fact that they ate foods that conflicted with the toxicity of potatoes, which led to the tragic result.
But in fact, the so-called detoxification of potatoes and sweet potatoes refers to the way in which the removal of potato and sweet potato tuber reproduction will lead to a sharp increase in pests and diseases.
It's in the potato breeding manual that Li Ke took out. I have to say, the country is awesome! There are all these things in that library, and this library is full of useful information! Anyway, Li Ke didn't see some useless books, and he couldn't find any music or the like.
As for this kind of agricultural technology, there are the most books on various crop-related technologies, and the explanations are very detailed, ranging from simple to advanced.
Take potato detoxification as an example. The simplest method is the variable temperature detoxification method, which is to keep the potatoes in a room with a temperature of 40 degrees for a certain period of time, and then lower it to a room with a temperature of 20 degrees for a certain period of time. Through this Temperature changes kill several diseases in potatoes.
The other method is to detoxify through bud tips, but that thing is too high-end and cannot be used in the current Datang Dynasty.
But in fact, can potatoes be grown without being detoxified? Can be planted! Not detoxifying potatoes will result in reduced yields, but in fact, the yield of detoxified potatoes is about 30% to 50% higher than that of non-detoxified potatoes.
That is to say, the yield per mu can be 2,000 kilograms per mu without detoxification, and the yield per mu can be 3,000 kilograms per mu without detoxification.
The question is, do you think 2,000 pounds was an artifact in Datang? ! This is still an artifact!
What Li Ke and the others can do is the temperature-changing detoxification method.
"Your Highness, the masters in charge of agricultural affairs said that they plan to use 80% of the potatoes directly for planting next year, and the remaining 20% will be divided into fifty parts for detoxification according to the temperature-changing detoxification method you 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.
