Chapter 747 Lingji Goes To The Moon?
"It's the experimental field stage!" Song He said.
The top picks are sluggish again, a testing ground? Is this going to be a test field?
Is the speed too fast?
"For example, when you are doing nitrogen fixation now, the road has gone a bit wrong." Song He shook the data sheet in his hand.
"The general direction is right. It has additional nitrogen fixation function, which can save money on nitrogen fertilizer. In commercial applications, even if the cost is reduced by one yuan, it may be able to defeat the opponent. But you are bored in the laboratory and do a hypothetical fixed value method. Totally wrong."
"Do you know why? Because your Lingbacteria production will ultimately serve desert farmland and actual agricultural production. Farmland is different from the laboratory. There are too many variables!" Song He emphasized.
"It is said that nitrogen grows leaves and phosphorus grows fruits. If it is a leafy vegetable crop, such as cabbage, greens, and amaranth, nitrogen fertilizer should be the main fertilizer."
"But if you grow fruits and vegetables, such as melons and tomatoes, you only need to apply nitrogen fertilizer in the seedling stage. After the seedling stage, the nitrogen fertilizer content in the soil is still high. The result is that only leaves will grow but no flowers will bloom, and the yield will drop sharply. Not to mention beans such as soybeans and peanuts. With similar crops, people can fix nitrogen by themselves, so there is no need to do anything extra.”
"Different soils have their own requirements for nitrogen fertilizer application. Do you know the main ways of nitrogen loss? The volatilization of ammonium nitrogen, the infiltration of nitrate nitrogen, the denitrification process of denitrification, and the fixation of soil lattice." Song He listed on his fingers.
"So the degree of looseness of farmland in each region is different, the specific effect of converting sand into soil is different, and the nitrogen fertilizer required is different!"
"There are also the effects of miscellaneous bacteria. When you are doing experiments now, you are using clean sand. First disinfect it to kill all the miscellaneous bacteria, and then introduce the Lingbacterium mucus into it. It is correct to do this in the laboratory, because the laboratory stage must be ideal. A little bit, but what about outside in the fields?”
"Soil bacteria are a very complex subject. It is difficult to say what dominant strains of bacteria will be encountered in each farmland. It is difficult to say whether different strains of bacteria will coexist peacefully or die together. Some bacteria may feed on Ling bacteria, and some bacteria, such as oligotrophs, There are types of Geobacter that help fix nitrogen, and there are even bacteria that like to swap genes, these are all variables."
"Climate is more important. You maintain constant temperature and humidity in the laboratory, but nature does not maintain constant temperature and humidity with you. Soil depth is also very important. In farmland converted from sand to soil, it is impossible to achieve such depth, right?" Song He picked up the small specimen jar next to him and shook it.
The more the three top picks heard this, the paler their faces became.
They do know that the farm environment is very complex, but they have not thought about it that much for the time being. They only want to create the ideal bacterial strain in the laboratory first, and then put it into practice later.
But the teacher’s requirements are beyond imagination, and it’s all about actual combat!
"Then... what should we do?" Ling Yiyi was nervous.
"Stop talking, let's go to the experimental field." Song He smiled.
The three champions looked at each other.
"Teacher, the experimental field...isn't it hard to find?" Xia Wansan asked.
"I'll find the test field for you. It's very simple. There are confidential bases in Inner Mongolia and Xinjiang that I'm familiar with. There are a lot of deserts nearby. I'll make a report to my superiors. Under normal circumstances, the land will be approved in about a month." Song He said, "There are also ways to speed up the process, and land can be approved in about a week."
"How to speed up?" Ling Yiyi was curious.
The door of the laboratory clicked, and someone swiped his card to come in. It was Lou Jinghui.
"Boss, are you looking for me?" Lou Jinghui came over and asked.
"Do you know each other?" Song He asked.
The three top picks and Lou Jinghui all knew each other. They had been working together in the laboratory for a long time and were very familiar with each other. Xia Wansan even often went to pick up express delivery for Lou Jinghui.
"Lou Jinghui is currently working on the moon vegetable project. The three of you are working on the sand-to-soil project." Song He smiled, "The projects of both of you can actually help each other."
The top picks and Lou Jinghui stared at each other and understood the meaning in an instant.
"Using Ling bacteria to make lunar soil to improve soil?" Ling Yiyi asked.
"Yes, lunar soil is basically fine powder produced by broken rocks. There is no water or organic matter in it, so it cannot condense into lumps. It is very much like special sand." Song He turned to look at Lou Jinghui and joked, "Right, lunar man? "
"Yes, it's all fine powder, heavy metal slag, Cylite and Si quartz, and even a little glass fiber." Lou Jinghui recalled, "An important indicator of the construction machinery we use on the lunar surface is dust resistance. Moon dust Once inside the machine, it is easy to malfunction, similar to what happens in the desert.”
"So Lingjie comes in handy to transform the lunar soil, changing the sandy lunar soil into dense and sticky soil." Song He said, "If you are willing to include Lingjie in the Moon City Project, then we will give you a batch of experimental fields The speed must be the speed of light, and it will probably be approved within a week."
The eyes of the three top picks all lit up!
"Okay!" Ling Yiyi was excited, "Even if it's not for the experimental field, Lingji can go to the moon, and we can also leave a name in the history of the moon!"
Pu Songchun nodded, "Contribute to the country."
"What a great advertising effect!" Xia Wansan clapped his hands, "I agree!"
"Okay, then you take the sample to Team Leader Lou for demonstration. Team Leader Lou has several boxes of simulated lunar soil. Try the effect. I will collect the data and report it." Song He said, "At eight o'clock tonight, you three Go to my office again and have a short meeting."
…
eight pm.
office.
Song He sat in front of the computer and clicked around, busy correcting students' homework.
He only corrects the homework of master's students. As for the hundreds of undergraduate homework, he naturally leaves it to the master's students to correct.
When I am promoted to full professor and can recruit Ph.D.s, I can only correct a few Ph.D. assignments and leave dozens of master's assignments to Ph.D.s to correct.
In short, the higher the level, the less homework needs to be corrected. Song He found that his task of being promoted to full professor was very urgent!
"Are you free? Help me correct the students' homework. I'm busy here."
"The corrections should be completed before nine o'clock. I have an online class at nine o'clock and I have to teach the students their homework."
A message suddenly popped up in the lower right corner of the computer. It was from the Prime Minister.
Song He responded with a small gesture of OK, reluctantly logged out of his account, typed in the dean's account number on the keyboard, and worked hard to correct her homework.
After being promoted to full professor, you have to find a way to usurp the position. It's even more fun to be the dean. You don't even have to correct your doctoral homework, just grab any teacher and do the work!
The question is, how to do such a difficult operation as usurping the throne?
Unable to think of anything at the moment, Song He shook his head. There was no point in thinking about things that were too far away. He should first be promoted to full professor as soon as possible.
"Dong dong dong!" There was a knock on the office door.
"Please come in!"
The door opened, and the three champions, Ling Yiyi, Xia Wansan, and Pu Songchun, filed in, each holding a glass jar in their hands.
Song He's eyes immediately straightened, like an antique dealer who saw a rare treasure and quickly reached out his hand.
