After spending a little thought, Zhang Qi put the telescope in his hand to the naked eye test.
By making a rough comparison of the shape and size of objects seen in the telescope at the same time as the other eye, he concluded that the magnification of the telescope in his hand was about four times.
Of course, it's not necessarily accurate, because what you can see with a telescope depends on your vision.
The function of a telescope is just to zoom in on distant scenery.
Just like this telescope, which is about four times the size, its function is to bring things 400 meters away to a distance of 100 meters in your visual field.
The principle is similar to glasses, except that imaging technology is used.
And to put it bluntly, what a telescope looks at is not things, but light. The more light is reflected, the clearer things you see.
Putting down the novel gadget in his hand, Zhang Qi nodded with satisfaction and praised the jade craftsmen who were still standing beside him.
"The craftsmanship is good. You will also recruit more apprentices in the future. This kind of telescope will inevitably be mass-produced in the future."
The old man looked a little excited. Among the craftsmen who came in with him, none of the craftsmen who came in now had 180 people under their command. That is to say, he had never been reused before and only had three or four apprentices.
"Hey, don't worry, Your Majesty. I will recruit apprentices right now. With your approval, those dolls will definitely be interested in this craft."
Zhang Qi smiled: "Don't worry, you guys will work hard and grind out the remaining materials. Of these two lenses, the larger one is the objective lens and the smaller one is called the eyepiece. The size of the objective lens is this for the time being, but the eyepiece
Take the piece in my hand as an example, and think about it step by step. Counting to five, first polish out five eyepieces that gradually shrink. "
"promise."
The old man was getting older, and his hands were shaking uncontrollably. Zhang Qi waved his hand, telling him that he would not have to salute in the future. For things like lenses, even in the 1960s and 1970s, the precision of handwork was higher than that of machines. Yes, it depends on the experience of the craftsmen, so this old jade craftsman is a treasure.
After instructing the old craftsman to take his apprentice to continue polishing crystal lenses, Zhang Qi went to look at those crops again.
Potatoes, corn, sweet potatoes.
These crops have been sown in the riding world for almost two months.
Now they are green and growing.
Because it was a test field, only one acre of each crop was planted.
The tallest thing is corn, which is now only a little shorter than a human.
In the potato field, buds were waiting to bloom. When he saw potato flowers growing out of the ground for the first time, Zhang Qi finally understood why they had become an ornamental plant in Europe.
It's really pretty.
The sweet potato is a little different. Compared with the corn and potatoes, the sweet potato is very inconspicuous. The sweet potato seedlings are crawling and growing in the ground. If you don't pay attention, you will just think that this place is a wasteland overgrown with weeds.
But Zhang Qi knew that when the sweet potatoes matured, these crops buried in the ground would save many people from hunger.
Zhang Qi is a little lucky, lucky that he is a time traveler, lucky that he knows the uses of sweet potatoes, potatoes and corn. Otherwise, according to the normal historical process, even Europe, which regards potatoes as one of the staple foods, did not treat this kind of potatoes when they were first introduced. Crops are resistant.
This resistance lasted for centuries. It was not until war, famine and other unnatural factors forced the European people to put potatoes on the table.
Squatting on the intersection of several acres of land, Zhang Qi squatted down, grabbed a handful of soil and rubbed it. In the days of time travel, he also changed from a half-hearted theorist who didn't understand farming and could only spread some information on the Internet. A semi-expert who can look at the fertility of the land and the growth of crops.
People are forced out. If you want to live a better life, you need to push yourself hard. What's more, this is an era with almost no obstacles.
The only thing he has to do is to clean up Liuhe!
"I've seen you, Your Majesty."
While Zhang Qi was checking the soil quality, several elders led a group of young people aged 18 or 19 to these experimental fields.
They are teachers of the Cavalry and Cutting Academy, and those young people are naturally students.
Zhang Qi stood up and hummed, waving his hand to stop the students from saluting.
"Is there an agriculture class today?"
Zhang Qi asked casually.
The head of the college teacher bowed: "Yes, you asked us to select high-quality potato, corn, and sweet potato seeds as soon as possible, so the school increased the agriculture class to four classes per week, and today happens to be the last agriculture class."
"That's right. Take good care of these three crops. If you do a good job, you will have the opportunity to leave a mark in history."
"Your Majesty's order, I will bear it in mind."
"Well, you don't have to worry about much with corn, but you need to pay more attention to potatoes and sweet potatoes. Also, their habits will cause them to continuously accumulate disease toxins from the nature of the land, so you have to think of a way to cultivate them without Poisonous seedlings.
Of course, the accumulation of toxins also takes time, so you don't have to be too impatient and just follow the normal process. "
Zhang Qi spoke eloquently.
Several teachers nodded, wrote it down in their notebooks, and then handed over their hands and agreed.
The students who were following the teachers were also carrying hoes and dustpans, looking at this side curiously, but when they looked at Zhang Qi, their eyes were full of admiration and admiration.
"."
After talking for a while, Zhang Qi also felt that he was disturbing the teaching of the college teachers, so he waved his hand, left the last words and left.
"Let the God Guards lead a few agronomy experts to the towns of Sturgia, where the climate is very cold, and cultivate a batch of cold-resistant crop seeds there, and then bring them back to hybridize with the crops here. The outside lands you I also knew that I needed some adaptable crop variants."
After finishing speaking, Zhang Qi left the world of riding and slashing in full view of everyone.
outside world.
The sun is shining and it’s another scorching day.
The cicadas chirped knowingly.
Come out of your bedroom.
Bai Xing was already waiting at the door, or in other words, she was guarding the door as soon as she discovered that Zhang Qi was missing.
"Your Majesty."
Seeing Zhang Qi coming out, Bai Xing bowed slightly.
Zhang Qi nodded: "What happened while I was away?"
"Reporting to your Majesty, everything is normal."
"Well, that's good."
"Come for a walk with me."
After crossing the threshold, Zhang Qi said softly.
Countryside.
Jiaoli is a county town.
The central governor's mansion is outside the county.
Therefore, there are several villages and towns more than ten miles away from the Duwei Mansion.
The two of them rode on horseback, followed by more than a dozen guards from the Captain's Mansion.
Seeing such a battle, the villagers did not show the same fear as other nobles, but instead greeted them warmly.
"Captain is well."
"General Zhang is doing well lately."
"Good morning, sir!"
There was an endless stream of greetings, and Zhang Qi could only keep smiling and nodding.
Since the last time he lent troops to Huo Qubing, his false identity title has been promoted from Shaoshangzao to Grand Concubine. If he has further merit, he will be named the Marquis of Guannei.
This time, the one Liu Che awarded Wei Qing for his first contribution was the Marquis of Guannei.
