The one called Brother Chen immediately replied: "I remember this. The temperature in the greenhouse fluctuates greatly. If the temperature difference is greater than 5 degrees Celsius, the vegetables will catch a cold! The leaves will crack, thorns will grow, goose bumps will appear, and the vegetables will curl up!"
After he finished answering, he asked Qiao Xuejun: "Isn't that right, Teacher Qiao?"
Qiao Xuejun smiled and nodded, apparently quite satisfied: "That's right."
She then randomly called on people to answer questions.
Zhao Xian was watching from the side.
After Qiao Xuejun started working, she didn't even look at him. She was very serious and efficient.
When she asked questions later, some people couldn't answer them, but she didn't criticize them too much and just asked the next person to answer.
The entire questioning process took no more than 5 minutes, and after it was finished, the speaker said, "Okay. Thank you for your hard work, and let's get to work."
Everyone dispersed, and Qiao Xuejun looked at Zhao Xian: "When will Haibao come?"
Zhao Xian said, "It's 7 o'clock now, they are almost here."
Qiao Xuejun was surprised: "Arrived? Then you said you could come over and take a look first."
Zhao Xian: "The meeting will take a while. Since they came at this time, I asked Wangwang to arrange for them to go to the cafeteria. And the injured person in Haibao, I arranged a meal and visit."
After that, he said, "Go do your thing first."
Qiao Xuejun nodded: "We have to take a look. They regard the First Base as a scourge."
The greenhouse is heated to 20℃.
Qiao Xuejun took off his down jacket and cotton-padded jacket, picked up a work suit from the side and put it on: "Then I won't worry about you anymore. I'll take care of the important things here first. Call me when the time comes."
She picked up this work uniform from a large men's singlet. It was tattered and not warm, but it could be used as a simple protection to prevent the clothes she wore daily from being worn out.
Qiao Xuejun said that she really didn't care about Zhao Xian, and took Xiao Feng into the newest tomato greenhouse. This is now her main focus project.
Zhao Xian also took off his coat and wore the thin black combat uniform underneath, following behind her closely.
The greenhouse was filled with growing racks, with wild vegetables on the lower levels and tomatoes on the upper levels. It was the first time he had seen what these growing racks looked like so clearly.
There is a plastic basket on each layer, and the plastic baskets contain growing vegetables of the same type.
Each plastic basket has two water pipe openings, simple water pipes, one in and one out, and the baskets are also connected by these water pipes.
Water circulates.
Qiao Xuejun walked among the hydroponic racks, observing the condition of the tomato seedlings. Zhao Xian heard her ask Xiao Feng, "Have you confirmed with the carpentry shop? Can the tomato racks and traction ropes be delivered today?"
Xiao Feng replied: "Sure, we've already discussed it and it will be delivered shortly."
"The nutrient solution should be changed tomorrow. The original solution is used up and needs to be re-mixed. Do you remember the formula?" Qiao Xuejun asked.
Xiao Feng scratched his head and said, "I remember Liquid A." But there were also Liquids B, C, and D. Each nutrient solution had a different formula, with a total of more than ten elements. It was hard to remember.
Qiao Xuejun smiled and said, "It doesn't matter. You'll remember it after doing it for a long time." She is the one doing this job now.
She said, moving towards the next planting stand.
Because the growing racks were collected from outside, they are of different sizes. This growing rack is relatively high, and the tomatoes are planted on the top layer.
Qiao Xuejun stood on tiptoe and opened the tray lid of the hydroponic tank with one hand, while trying to insert the pH measuring pen in her hand into the hydroponic tank with an awkward movement.
Zhao Xian walked over directly, took the measuring pen from Qiao Xuejun's hand, and easily inserted it into the measuring pen to measure. After the measurement, he gave Qiao Xuejun the reading: "6.3."
Qiao Xuejun nodded: "No problem. Let me test this too."
She also handed over the EC value measuring pen.
Zhao Xian took it and took the reading: "1860."
Qiao Xuejun: "That's no problem."
The two went to the next planting rack.
Xiao Feng followed the two of them without saying a word, like a quail.
He wasn't much taller than Teacher Qiao, so he couldn't really help with this sort of thing. But he was now Teacher Qiao's assistant, and the training leader had emphasized the importance of acting according to circumstances.
Later, they held a special meeting and told them that Teacher Qiao's hands were not convenient and they should help her when necessary.
Oh my God, the lord won’t replace him, right?
Amid Xiao Feng's anxiety, the inspection continued.
Qiao Xuejun walked to the front to look at the tomato seedlings that were still being grown nearby. At this stage, they had not yet been placed in the hydroponic racks.
Seventy or eighty planting cups of tomato seedlings are placed on a tray, and the trays are layered on the planting rack.
Zhao Xian looked at Qiao Xuejun and suddenly said nothing, then reached out to lift one of the trays.
Zhao Xian's eyebrows jumped. The tray looked like it weighed more than 10 kilograms.
He held her hand: "What do you want to do? I'll do it."
Qiao Xuejun reacted and her first reaction was to argue: "This is not heavy."
Xiao Feng quickly stepped forward: "I'll do it, I'll do it."
Zhao Xian didn't let Xiao Feng come up. He moved diligently and lifted the tray with one hand: "Tell me, where do you want to put it?"
Qiao Xuejun pointed to the floor below: "The lighting here is uneven. Switch the two plates up and down."
Zhao Xian lifted up the other plate as well and swapped them up and down.
Xiao Feng feels that he has a lot of free time.
But this time, he couldn't be blamed, could he? He had already taken the initiative, and the lord hadn't let him go up, insisting on helping in person.
It has to be said that this position is much easier than he initially thought. Teacher Qiao is very good at doing things on her own. Many times, Xiao Feng feels that something he should do himself, but Teacher Qiao doesn't even call on him. Sometimes, before he even realizes it, Teacher Qiao has already completed it.
