Qin Hao and Ma Dexiang went to work as usual. Su Mi also continued to paddy her two vegetable greenhouses on the patio.
Because the newly planted seeds had a tendency to germinate after being watered with stream water on the first day, Su Mi did not dare to water them directly with stream water the next day.
If you continue to water it with stream water, the seeds will grow into mini seedlings the next day. Such an incredible thing must not be allowed to happen in front of others, not even Qin Hao, Tiantian and Ma Dexiang.
Therefore, Su Mi considered using tap water. However, after being poured with tap water once, it was obvious that where the seed skin burst, the originally full and green shoots inside were greatly reduced in vitality. There is a tendency to wither.
Su Mi immediately thought of the reason for the inability to grow plants in the base. I'm afraid it was not only the soil, but also the water quality that had a great impact.
Polluted water not only cannot allow seeds to absorb and germinate, but will also cause the seeds to lose vitality and even die in a short period of time.
You cannot irrigate directly with tap water, and drinking drinking water is too wasteful. No matter how much water there is in her space, there will be a day when she runs out of water.
Watering with these is indeed a waste. Is there any way to filter out harmful substances from tap water? Su Mi had previously thought about going out to find a water purification device, but due to a tight schedule, she could only make her own one first to see if physical filtration would work.
There are buckets of purified water everywhere, and you can exchange one steamed bun for two at the store. Su Mi cut off the water outlet of one of the buckets and cut out a larger round mouth.
Cut off the bottom of another bucket and turn the bucket upside down with the water outlet facing down. First, tie two layers of fabric cut out of pure cotton short sleeves to the water outlet.
After fixing the two prepared buckets one above the other, Su Mi began to worry about which filter material was better. The fine sand and stones on the ground cannot be used. After all, the heavy rain has just passed, and the land is too polluted for planting. Who knows whether the fine sand and stones have been contaminated.
So Su Mi set her target on the red bricks in the space, so she chose an already broken red brick, knocked it into even smaller pieces, and set it aside for later use.
Her father had raised fish before his death. Su Mi knew that in order to simulate the water quality of fish in the natural ecological environment, the filtering material needed not only rough filtering stones, but also natural fine sand to decompose harmful substances in the water, and naturally also More delicate physical and chemical filtration is needed to filter out harmful substances such as bacteria and parasites in the water.
But Su Mi thought about it for a long time and had no idea. Things in the outside world couldn't be used for the time being, so what about the space?
Su Mi finally focused her gaze on the black soil in the space.
The black soil is soft and full of nutrients. The most important thing is that it contains thin spiritual energy belonging to space, which can be used to decompose the sediment.
As for other things, Su Mi didn't have them on hand at the moment, so she finally decided to try these two things first to see the filtering effect.
In the upside-down bucket, Su Mi filled the bottom part near the water outlet with a mixture of black soil and crushed red bricks. On top of it, she laid a layer of pure cotton cloth cut from clothes and then a layer of red bricks. The pieces are crushed into fine powder.
Then a layer of black soil, a layer of cloth, a layer of red bricks and a layer of cloth filled the bucket halfway, and Su Mi used a larger piece of cotton cloth to cover the upper water bucket and fix it.
This layer of fixation is regarded as the first layer of physical filtering.
So Su Mi poured a large bucket of water and went to the patio to start experimenting.
In addition to the smell of bleaching powder, the tap water in the bucket also contained many small substances upon closer inspection. There are many things that are visible to the naked eye, but there must be more that are invisible.
After the water is poured into the water storage bucket, it is filtered through the first layer of cotton cloth, leaving no obvious impurities on the cotton cloth. The water enters the water storage bucket and begins to soak through the filter material of the sumi pad layer by layer. Finally, it flows to the bottom water outlet and drips into the empty bucket below.
The filtering speed was not fast at first, but later, the dripping speed became faster and faster, and soon all the water stored in the filter bucket above was filtered out.
Finally, I got a bucket of water below that didn’t meet the watering standard.
So I took out a cluster of seedlings that sprouted in the space, poured water on it and gave it a try.
After waiting for a few minutes, the seedlings did not show any signs of reduced vitality or other problems. Su Mi brought a small bowl over, poured some filtered water into it, and soaked the seedlings in the water.
I took it out ten minutes later and there was no change at all. It did not reduce the vitality and wither the state, and after soaking the seedlings, the leaves became more upright and greener.
"It seems to be successful. In this way, filtered tap water can be used directly for irrigation."
Su Mi smelled the filtered water and found that there was no smell of bleaching powder at all. It was clear and clean. It should be fine for washing vegetables and clothes, but she didn't know if it could be used for daily drinking.
Today, except for going out for breakfast in the morning, Tiantian has been staying in the living room with his eyes on the second-grade elementary school textbooks that Qin Hao found for him and assigned homework, so Tiantian did not follow her today.
It's already noon now that Su Mi has finished these things, and it's time to eat.
There are three big steamed buns left in the morning, each one is very big, and you will be very full after eating just one. Su Mi felt that the steamed buns were too bland, so she found a pack of pickled mustard and sausage from the space to eat.
Tiantian was very happy about Su Mi's behavior of opening a small stove, and never mentioned it to Qin Hao and Ma Dexiang. Gradually, this became a little secret between him and Su Mi.
In the evening, Qin Hao still brought back prawns, and this time there was even an extra bream.
Ma Dexiang came back with a bag in his hand containing a small handful of rice. “This is replaced by white porridge in the morning and lunch and steamed buns for work lunch, and I pour it directly into the rice bag.
Alas, the food at home still smells good. "
"Brother Hao, your cooking skills are as good as mine. The big steamed buns you steamed in the morning are so delicious. How about we get more food in the morning and we can bring lunch by ourselves.
The work meal was made with tap water, and I could barely manage to eat two bites.
How can I still swallow it now? And your braised prawns are simply delicious. "
Qin Hao nodded, "There is still a lot of flour at home. This is enough for us to eat for a month. Plus rice, we can eat it for a long time."
But Qin Hao was not thinking about this issue at this time. "Su Mi, we have been spending so much and not going out to search for supplies. We will definitely not be able to pay next month's rent just relying on the income from Lao Ma and I's work.
Even moving to a small building may be difficult. "
If Qin Hao and others were told at this time that they were going to move to Tongbu House, they would never accept it. After all, it is easy to go from simplicity to luxury, but it is as difficult as climbing to the sky from luxury to frugality.
Su Mi smiled mysteriously, "Don't worry, you are responsible for cooking and cleaning every day. Just leave the rent to me. Don't worry."
The second update is coming
It's the end of the month. Clear all the tickets in your hands and give them to me.
