Chapter 1342
Zhang Feng's words.
All the students were in an uproar instantly.
Even with Yu Shinan on the stage, they hurriedly came to Zhang Feng’s side with Sun Simiao wearing masks. Li Shimin wanted to come, but he was firmly pressed by Niu Jinda. On the stool, I can't get up even when I think of it, and the sky is full of red.
Li Shimin was pressed into a hurry, staring at Niu Jinda and said: "What do you mean by this?"
"Second Lord, you should bear with me first. But you know the formidable power. I don’t dare to smell this thing. Feng'zi is young and he can resist..."
"Then you mean, my body is very bad?"
In an instant, Li Shimin's words shocked Niu Jinda's body.
Busy explanation: "no no no, I mean...it is..."
After a long time, Li Shimin became impatient and said: "I will come today , For this thing, if even I shrink back, wouldn’t it be laughed off if it spreads out?"
Wei Zheng and the others were also made up by Niu Jinda and His Imperial Majesty. It was very scared, but when it was seen that it was because of this incident, Wei Zheng also hurried forward and persuaded Li Shimin.
"Second master, just watch it, don’t step forward!"
"Yes, yeah, second master, if you come forward, then we have to What a sin?"
Li Shimin understands it.
These people have already discussed it.
I'm just afraid of what he will do.
I'm just afraid that something will happen to him, but if he doesn't go today, if he doesn't witness it with his own eyes, he is really sorry for his conscience!
"Shut up!"
Li Shimin whispered slightly warmly, and instantly made several people shut their mouths.
Although Yu Shinan and the others heard it, it is hard to say anything. After all, this is something about the Imperial court. What can they say?
Moreover, it was the first time they saw this thing, and it was strangely tight.
After all, some things are really impossible.
Under Li Shimin's scolding, although Fang Xuanling and the others are still a little unwilling, after all, this is a mountain, they dare not say anything, so they have to get out of Li Shimin.
Li Shimin thought about it or put on a mask.
Actually, he really doesn't want to wear this thing. He always wonders if this thing is a little ominous.
But if you don't wear it, it will make everyone boring, so Li Shimin chose to wear this thing anyway.
When a few people stepped onto the stage, the extraction of the first round was over. Zhang Feng was sorting out the residue in the appliance and a small amount of phosphate fertilizer that was extracted.
The extraction of phosphate fertilizer is actually very simple. It is to add some Nitric Acid sodium, which is lime powder, into the water, and then introduce the high-temperature distilled phosphorus element gas into the water. After the chemical reaction, precipitation The next thing is phosphate fertilizer, also called Nitric Acid Phosphorus.
This is also the simplest thing that Zhang Feng can manufacture based on the things of the current era.
It is also the most acceptable thing for everyone.
Zhang Feng is actually very difficult.
These things are actually unnecessary, but on the one hand, they can’t stand it anymore. On the other hand, he really doesn’t know the issue of locust plague next year. After all, only through this year’s In terms of planting and irrigation, only by wrapping medicine powder in the water can a series of obstructions be achieved, and some things next year will be able to kill the locusts.
But...
To complete the eradication of locusts, Zhang Feng does not have that great ability yet. At the very least, he has to wait until the hot air balloon can be accepted by everyone and use the heat It is possible to stop the locusts by spraying pesticides on a large scale with balloons.
This is only within Great Tang. As for things outside of China, Zhang Feng can’t control that many. But even so, whether the time comes or not can stop the locusts, that’s two different things. Therefore, under the premise that the people who can ensure at least their own Academy next year, and Old Li and the others are not hungry, and Old Ox found this thing accidentally, this made Zhang Feng think of this method.
Otherwise, Zhang Feng really doesn't want to engage in this troublesome thing.
Besides, I was stabbed out so hard. If it doesn’t spread after the spring harvest next year, it doesn’t matter.
But, this fucking let the old bastard with the surname Kong come to the mountain and quietly spread the phosphate fertilizer thing?
This is what happened later.
So, Zhang Feng is indeed in a bad mood today.
This feeling of being put together makes him feel very depressed. Therefore, since you are guessing, I will show you the show directly, and let your strategy be hidden from the sky. Not afraid,
This is where Zhang Feng's confidence lies.
Those who believe in me can make a round belly, those who do not believe in me, hehe.
Go for your blessings.
Li Shimin and the others wandered around the experimental platform, while Li Chengqian assumed the role of a guide, introducing the concept of the experiment loudly.
And some things on the experimental platform, the professional terminology.
For example, what are the ingredients such as Nitric Acid sodium.
Not to mention that Yu Shinan and the others have been thinking about Zhang Feng's physics teaching book all day long, even if it is more than three thousand students, it is not calm to hear at this moment.
This thing, is it really something we learn normally?
See Zhang Feng not speaking.
A student hurriedly stepped forward and asked loudly: "Dare to ask Lord Dean, this thing called an experiment is really so magical, such a thing, that thing like snow can make food soar. The yield of phosphate fertilizer?"
