Who knows! As soon as I returned to the mountains to farm, I encountered a natural disaster.

The large hailstones were mixed with raindrops, which restored some life to the whole meadow after being thirsty.

But when it tried to grow upward, it was knocked back into the soil by large hailstones.

The two of them hid in the house and did not dare to go out. They only dared to go out in the morning when they had to feed the livestock and when they needed to take care of their own physiological needs.

You have to hold up a wooden board when you go out, otherwise such a big hailstone falling from a high altitude will knock someone unconscious if you are not careful, and the unlucky ones will probably die immediately.

The two of them had previously speculated that this year's high temperature lasted for an abnormal time, and estimated that the temperature would be even lower in winter.

The sudden change in weather and temperature difference now corroborated their speculations.

It seems that not only the previous houses need to be reinforced, but also the small brick house they live in now needs to take some measures.

Last winter, when the fireplace was fully burning, the indoor temperature could barely remain above zero, and the closer to the fireplace, the higher the temperature.

In the last few days, when there were snowstorms and extremely cold temperatures, the only place that was warm in the house was near the fireplace.

If blizzards and extreme cold become the norm this winter, it’s unlikely that the house will be warm.

The two plan to upgrade the heating system of the brick house.

Mu Xi's original idea was to have a bed, but Zhao Yeqing felt that just keeping the bed warm was of no use. It would be better to warm the entire room.

She wanted to build a floor heating system under the brick house.

Zhao Yeqing's idea was well-founded. She pointed at the foundation on the original drawing of building a brick house and said:

"Previously, in order to prevent moisture, a raised ceiling was built under the foundation. The ground of the house does not touch the ground. We can lay the floor heating in the middle raised position."

She took a new drawing, bit off the cap of the pen with her mouth, and drew the structure of the floor heating with two strokes.

"Look, the floor heating is just a hot spot. It transmits heat through pipes to the ground of the entire house. We use bamboo to make the pipes, and then the hot spot burns fire to provide heat."

She thought of all the points, and marked the materials and construction. Mu Xi took the drawing and understood the meaning.

First make a pit in a place, place the fire-burning stove inside, and then connect the stove with pipes to allow the smoke to pass through the pipes and bring heat to the entire underground.

The pipes connecting the stove parts cannot be made of bamboo, and are marked to be connected with metal.

Zhao Yeqing explained: "This is for fire prevention. All you need is a small piece of iron sheet. You can just get some iron buckets in the tourist area, or you can pry the exhaust pipe of someone's car. This equipment can also be used in the breeding basement." use."

As long as pipes are laid under the soil, the heat brought by the smoke will also warm the soil under the feet.

And their bottom is hollow. According to Zhao Yeqing, they don't even need pipes.

"Theoretically it should work. All you need to do is connect a pipe to the stove to the underground of the house, and then set up two smoke outlets on the other side."

But this is just her theory, and the actual implementation should not be that simple. However, this method saves the step of knocking open the floor. It only needs to dig two holes in the foundation part to allow smoke to escape and enter.

As a pure southerner, my understanding of heating is based on my exposure to film and television works, my own understanding, and the knowledge points in physics textbooks that have almost all been returned to teachers.

Only practice brings true knowledge.

But now all their thoughts are just thoughts. The hail outside has not stopped all day long, so the two of them can't do anything.

The raw materials for the red bricks have almost been used up, and almost all the red bricks have been fired. The two predict that there is still a little more to do, and they will have to dig some more when the hail stops.

Zhao Yeqing took the shoe mat in the room and started sewing.

She now knew why the old ladies in the village liked to sew insoles and knit sweaters.

This is indeed a great way to pass the time when there isn’t much entertainment.

The two of them have put in the solar panels outside. In this weather, the sun is completely blocked.

Only the stored power in the battery can be used.

Both the refrigerator and the grow lights were consuming electricity, and the two of them didn't even dare to turn on the fans.

Fortunately, the temperature has dropped now. If I don't turn on the fan, I just open the window a little, and a cool breeze can blow in.

People who have been baptized by a summer with a high temperature of 50 degrees have adapted well to temperatures of more than 30 degrees, and even feel a little cold.

The hail gradually stopped falling all day and night, but the dark clouds in the sky still did not disperse.

As if not wanting to waste the thick accumulation of dark clouds, heavy rain began to fall immediately after the hail.

The power reserve of your home's power supply is gradually running out.

The two of them unplugged the refrigerator. Now, except for some vegetables, there was nothing special that needed to be kept fresh.

The remaining electricity is given priority to the exhaust system in the basement.

The power of the grow lights cannot be saved. The sun is blocked by dark clouds. Even if there is no overheating sunlight, the grow lights can still be relied on to supplement the light.

But the sudden cooling and heating of the temperature still caused problems for the fruits and vegetables in the basement.

Three days after it rained, Zhao Yeqing discovered that white powder appeared on the strawberry, cucumber, and watermelon plants in the basement.

This is a bacterial disease and is also contagious.

Watermelons and cucumbers may be contagious. Both plants are members of the cucurbit family, and powdery mildew is contagious to each other.

Strawberries are not. They are plants of the Rosaceae family. They are in the same family and genus as roses and other roses. Powdery mildews from different families and genus are not contagious. However, strawberries can’t stand the squeamishness of strawberries. They will easily become susceptible to sudden cold and heat. powdery mildew.

Zhao Yeqing asked Mu Xi to bring the plastic film from the tool room. First, use water to wash away all the white powder on the plant leaves that had white powder. After the leaves were slightly dry, they covered them with plastic film.

The things her eldest nephew left for her previously contained pesticides to treat white powder, but the basement was not ventilated, so the best way to deal with the disease was physical control.

Powdery mildew bacteria will be killed at temperatures above 30 degrees Celsius. The current normal temperature in the basement cannot reach that temperature, so we can only use plastic film to cover it to increase the temperature.

The germs can be killed by just suffocating, and the treatment method is very green and healthy.

I hope the weather will no longer be erratic, otherwise these diseases will still reappear.

Zhao Yeqing swayed in the rocking chair, holding a bowl of tomatoes mixed with sugar.

While I was eating and watching a video, a strong wind began to blow outside the window.

The blowing made the glass windows sway back and forth in the wooden window frames, and the "tapping" sound made people feel uneasy.

I thought that the wind was blowing to cause another moth, but I didn't expect that God would actually start to play tricks on me.
