Therefore, a second phase of construction is necessary to add heating equipment.
Zhao Yun said from the side: "The diagram I drew is about a hot air blower that uses blue oil as fuel."
This has to run 24 hours a day, which consumes a lot of oil, but it is worth it to grow crops. His brother can lose anyone's blue oil, but he will never lose the blue oil of the Ministry of Agriculture.
We always say that food security comes first.
Qiao Xuejun: "It's not necessary before the temperature drops significantly."
As she spoke, she turned around and asked Kuang Qianli, "I asked you to pass on the dried rabbit meat to the Xie family. Did you do it for me?"
Kuang Qianli nodded: "Don't worry, I'll give you all 20 cans."
Qiao Xuejun: "That's fine."
Now Kuang Qianli goes to work in the engineering department every day, and she specifically assigned this task to him. He doesn't talk much and is stupid, so he will believe any excuse she makes up without looking into it further.
If it were Dr. Wang, he would have to know about her being dragged into the sea by a sea monster.
The fish skins are all set up, the door curtains are covered tightly, and there are ties and buttons to ensure that it is airtight.
Kuang Qianli looked at the four connected greenhouses and exclaimed, "They really look like real yurts."
It's just a different shape.
Qiao Xuejun led them into the greenhouse.
"Wow, it's a lot warmer in here." Kuang Qianli exclaimed.
Even though it had just been built and hadn't had time to warm up, the temperature seemed to have risen a lot without the cold wind outside.
"But it's so dark." There's no light at all, and I have to use a flashlight.
Zhao Yun said, "The lights will be brought in soon. That will be very fast."
Because the city salvage team really gained a lot of things, Zhao Yun spoke with confidence.
The shelves in the greenhouse are still empty now, but soon Qiao Xuejun will fill them all with plants.
She could already imagine the bountiful harvest that would come.
·
As soon as the lights were brought in, Qiao Xuejun started growing vegetables that night.
The first thing she planted was the spinach she had been longing for.
She does this work in the shelter.
In the evening, Wang Juanfeng got off work and went home to the planting area.
Qiao Xuejun sat inside the planting area and placed a small table. The ground next to the table was covered with some broken plastic pots and cups.
Qiao Xuejun was holding a plastic cup and cutting a slit in the cup.
Wang Juanfeng came over and asked: "Why are you still busy? Have you eaten?"
Qiao Xuejun was busy with her hands, and replied, "I ate it at the base."
Wang Juanfeng sat beside her and picked up a cup on the table that she had cut holes in all over. "What is this for? Growing vegetables? Such a small cup."
She was holding a disposable plastic cup.
Qiao Xuejun: "I collected it from the city this time and used it to grow hydroponic spinach."
All the broken flower pots, plastic cups and bottles she had picked up earlier were put to use.
Cut off the bottom of a mineral water bottle, cut a few holes in the bottom and sides, put some stone particles inside, and a planting cup is ready.
First plant the seeds in this planting cup and soak them in clean water. After they grow roots and leaves, transplant them to the greenhouse and soak them in nutrient solution, and then they can be cultivated normally.
Wang Juanfeng was curious: "Hydroponics? No need for soil cultivation?"
They have always grown vegetables in soil.
Qiao Xuejun: "We didn't have the conditions before. Now we have greenhouses. Spinach has shallow roots." If the roots are too deep, it won't work. In the past, we couldn't grow potatoes, corn, or pumpkins hydroponically.
She cut another cup: "With hydroponics, you don't need soil, you can plant multiple layers, increase yields, mature earlier, and save water."
The advantage of hydroponics is that you don’t need soil, you can naturally grow multiple layers, and the maturity time is one or two weeks faster than soil cultivation, and you can harvest in a month.
It also saves water. Growing spinach hydroponically can save 90% of water, saving manpower and material resources.
Wang Juanfeng was surprised: "So many advantages? Are there any disadvantages?"
Qiao Xuejun raised her eyebrows and smiled: "The disadvantage is that it requires professional skills, and I have it all handy!"
It is not a big deal for ordinary small-scale family planting, but large-scale planting requires certain technical management. You need to understand the configuration and circulation of the nutrient solution, and you need to master the determination of the pH value and EC value of the nutrient solution.
Qiao Xuejun has experience in these things, and the necessary equipment is also available in the engineering department of the base. He is not worried.
Wang Juanfeng looked at the pile of broken flower pots and plastic cups on the ground and said, "There are still so many? It's already 9 o'clock. Why not do it tomorrow?"
Qiao Xuejun focused: "I don't want to delay any longer."
She wished she had a hundred hands so she could finish the job in one day.
Her Ministry of Agriculture also applied for manpower help at the base, but the Ministry of Agriculture is an important department, and Zhao Xian is still reviewing the people, and people she is not confident in cannot enter her department.
Qiao Xuejun didn't want to wait, so she started working on her own.
Wang Juanfeng was sitting next to him and found a pair of scissors to help: "Why don't you go to the cubicle? It's a bit cold here."
Qiao Xuejun: "I'm just taking advantage of the situation here."
Because there is so much grain, Qiao Xuejun in the planting area has turned on the lighting mode to extend the lighting time of the cotton and save blue oil.
Although the teammates were surprised by the light, they had always thought that the shelter had its own lighting and did not have too many doubts.
However, in addition to taking advantage of the light, Qiao Xuejun's main focus is on temperature. Her spinach seeds have already been soaked, which has very strict requirements on the temperature, which needs to be around 20 degrees.
The constant temperature system in the growing area applies to all crops, so she doesn't have to put the seeds into a special incubator.
"You help me cut the cups, and I'll get the soil and seeds."
With Wang Juanfeng's help, she put down the work of cutting the cups and put sand on the cut planting cups.
