Chapter 496 492. Go to the fields to work
in the afternoon.
All the students and teachers returned to the stage.
Gather in the lobby outside Greenhouse Lab No. 2.
At noon, the place underwent some renovations, including a projector being connected and rows of chairs being arranged.
After the teachers and students took their seats.
Luo Hongzhi walked to the front of the curtain and began to briefly explain what the off-site application of soybean pollen is.
Simply put, most of the soybeans grown now are hybrid varieties.
And it is artificial selection.
Hybridize two or more soybean varieties that are never found in the natural environment.
This will lead to a problem: the flowering periods of the male and female plants are different.
Or the male and female plants have different growth requirements and cannot be planted together.
This requires collecting pollen from one of the soybean varieties, artificially pollinating it, and then breeding seeds.
And the first step is to pick the flowers.
There is currently no machine specifically for picking soybean flowers, so they need to be picked manually.
Luo Hongzhi spoke eloquently on the stage.
Luo Yihang felt deeply relieved.
This kid went out several times and stayed up late to be Shi Juan's assistant for several months, so he has learned the skills.
When giving lectures in front of so many college students, PhDs, masters and professors, you can't tell at all that I only have a junior high school education.
So, knowledge needs to be learned, but it is also important that knowledge can be used.
After explaining the principles of off-site application of soybean pollen.
Luo Hongzhi picked up the radio and said, "Release the drone."
Operate the computer at the same time and switch to the real-time image on the projector.
The projection screen showed the soybean field that we visited in the morning.
Two young men wearing Qingyin agricultural work clothes released two small palm-sized drones, which flew into the fields one on the left and one on the right.
Luo Hongzhi clicked again.
The screen changed to an overhead view of a soybean field.
It is gradually being covered by green, red and yellow.
After a few minutes, the entire soybean field was completely covered with various colors.
Luo Hongzhi performed another operation and a progress bar appeared on the screen.
While the progress bar is moving.
Luo Hongzhi introduced: "What we just released are two small surveying and mapping drones equipped with six spectral cameras, which can evaluate the health status, growth density or type of plants by analyzing the spectral characteristics reflected or absorbed by plants."
"Of course, this also includes flowering, because the spectrum of light in flowers is different from that of plants."
"After data collection, it will be sent to our data processing center for analysis. We have already recorded the spectral characteristics of soybean flowers."
"Once the processing is completed, we will know which area has more flowers, which area has fewer flowers, and what the density is."
As soon as he finished speaking, the progress bar came to the end.
The picture on the screen changed suddenly.
The colorful layer disappeared, returning to the original bird's-eye view of the soybean field, except that there were more dense white dots on it.
"Here we use a block of 10 square meters. The number of soybean flowers in a block is a dot. The more flowers there are, the bigger the white dot is. You can see that the number of flowers in our soybean field is relatively even."
"I'm not bragging, but our soybeans are very good."
Many people present laughed, both at Luo Shaoan's shameless self-promotion and at the fact that the crops were growing so well.
At this time, someone in the audience suddenly asked, "I just heard that it can also assess the health of plants. Can diseases also be identified?"
Luo Hongzhi replied: "Yes, as long as there are records in the database, we can tell whether it is diseased or infested with insects, and what kind of disease or insect pest it is. Not only diseases, but also whether it is lacking in fertilizer, water, or light, and what kind of fertilizer is lacking." "If we use a close-up agricultural monitoring camera, we can even see the condition of a particular plant. We will use this method to scan the fields regularly to find the origin of the disease and kill it when it sprouts."
“It’s an important part of precision agriculture.”
This answer caused a burst of exclamations. All the students here are agricultural students, and many of them don’t even know that such a thing exists.
Not to mention the high school students over there, they were even more excited.
Many people raised their hands and asked questions.
Luo Hongzhi looked around, unable to cope with it. There were many things he didn't understand.
At this time, only Luo Yihang stood up and clapped his hands to quiet everyone down. "Please don't be anxious. We will demonstrate many new things later. Tomorrow afternoon, I will invite the developers of these devices to have a video conference with you. Students who are interested can prepare some questions and ask them directly tomorrow. Now let's continue our tour experience, okay?"
"Okay!" the college students agreed in unison.
It’s a great thing to be able to connect with the developers. Students who are interested in this have already taken out their notebooks and started organizing their language.
When the situation calmed down, Luo Hongzhi continued, "Our next task is to pick soybean flowers. I hope everyone will be divided into 40 groups, with six people in each group, five adults and one minor, and we can form groups freely."
When these words were spoken, the college students became excited and said, I am an adult.
Bring a minor.
High school student.
Those who had been playing well with them before have already started making eye contact and gestures to recruit others to join them.
As for working in the fields, we are all studying agriculture and are already prepared to work in the fields, so it doesn't matter.
after that.
Luo Hongzhi performed some operations on the stage. On the overhead view of the soybean field, he used red lines to divide it into 41 irregular areas and wrote numbers on them.
Then Luo Hongzhi pointed at the screen and said, "Please look, I divided the soybean field into 41 areas, and the amount of flowers in each area is the same."
"Why is it forty-one and not forty?"
"Let's have a competition. Our company will send out six people. Let's see who can pick the fruit faster, okay?"
Competition? Sure.
but.
"What's the reward?"
Someone called out the issue that they were most concerned about.
Luo Hongzhi was stunned when he heard this. Isn't it said that young people can't stand provocation? Why is it so realistic?
Nonsense, they have been in contact for a whole morning. They have seen the size of these kids from Qingyin Agriculture, and also seen the work they did when they were tour guides.
It's so powerful, but who would do it if there is no benefit?
Luo Hongzhi scratched his head.
What kind of reward should be given?
Luo Yihang had to step forward and ask, "What reward do you want?"
“Proof of internship!”
This time the answer is quite unified.
Luo Yihang waved his hands repeatedly, "That won't work. Wouldn't it be considered fake if I just gave him the internship certificate?"
The college students were just about to sigh.
Luo Yihang said again, "The winning team, when you need an internship, please contact our company. We will send you an invitation to come for an internship. There will be an internship salary, including food, accommodation and travel expenses. Okay?"
Okay, of course it’s better than just getting a certificate.
The college students were all shocked and shouted, "Compete! Compete with them!" and "Who's afraid of who?"
"Okay!" Luo Hongzhi also shouted, and then pressed the keyboard.
A QR code appears on the projection screen...
