Chapter 216: Traditional Methods to Filter Out Insect Eggs
To solve the problem of insect eggs from the root, the only way currently is to filter out the eggs through a filtration system, but the embarrassing thing is that they are all flooded.
If this happened before the end of the world, it wouldn't be a big deal. We could immediately and urgently manufacture a batch of ultrafiltration equipment. Every household in the United States drinks water directly, which has already been filtered in the factory. This wouldn't even be a big deal in the United States.
But it is very difficult to produce these devices now, especially some precision accessories, because the raw materials are really hard to find. For example, the filtering equipment and the filter element are not produced together, and there are hundreds or thousands of raw materials needed to produce a device.
So we can only salvage the equipment produced in the past.
But there's only so much equipment, and there are too many people and too little meat. While people are fine drinking the worm egg water in the early stages, when large numbers of evolved worm eggs appear soon, drinking this water can lead to daily stomach aches, diarrhea, and even dehydration...
There used to be lumps of it on the floor, but now it's just puddles... Ugh. I heard on the news that it's a reaction between bacteria and your stomach, just like when you have diarrhea after eating something bad.
By then, both the ultrafiltration system and mineral water will become extremely precious. If you have the conditions, you will enjoy immense comfort, but if you don’t, you can only endure it.
Finally, someone was smart enough to try various methods and was able to filter out some of the insect eggs.
"Mom, if the filtration system can filter out insect eggs, then our ancestors' method can also filter out insect eggs."
Jingshu said slowly.
"What can we do? We can't install our filter there. The little water we filter every day is not enough to water so many vegetables."
"You mean something else? Well, I've tried a lot of filtration methods for survival in the wild, but those don't filter out insect eggs, so they don't meet the requirements. I heard from researchers that insect eggs are invisible bacteria. How can such tiny bacteria be filtered out?"
In addition to ultrafiltration, are there any other ways to kill insect eggs? This has become the hottest topic recently. Look at Zhu Chuangshi, who came up with that method. Not only was he interviewed by a TV station, he also became an Internet celebrity in China. Now he is invited to remove insects every day, but Zhu Chuangshi's method cannot cure the disease completely and is difficult to promote.
Then there are ultraviolet disinfection, chemical disinfection and the like, which can drive away some of the insect eggs, but the remaining insect eggs can still eat the crops and prevent them from germinating.
"Come on, let's go to the back mountain to find materials. I'll go to your workplace to try it out for you tomorrow." Jingshu said mysteriously.
Jingma doesn't believe it. With technology so advanced these days, what use are those ancient methods? They definitely can't reach the standard of drinking water.
The standards are definitely not met, but wouldn’t it be fine as long as we can grow crops in a different way?
Jingshu took Jingma to the back mountain and searched and picked up things for an entire afternoon, picking up all kinds of minerals and stones, and even yellow mud.
After pulling a whole cart of things, Jingshu was woken up by her eager mother Jing's pull to go to work at four o'clock the next morning.
Jingshu first wrapped the soil with cloth in the order of large, medium and small at the faucet. After three layers of screening, the water seeped down layer by layer and filtered out the red nematodes. The soil had to be replaced every day.
Then Jingshu spent a whole day building a super large pool.
The water that passes through the first layer of filtration will enter a "concave" shaped pool.
The first compartment contains a pool of large stones, large pebbles, small pebbles, rubble, fine sand, and yellow mud. After sedimentation, the water flows into the second compartment, which is a pool made of bricks and contains charcoal and fine sand.
Jing's mother seemed to be hesitant to speak. She had used this method before, but the results didn't seem to be ideal.
However, basic filtration is indeed completed at this step. The third grid is a large water storage pool with a wooden plug on the upper part. When it is full of water, it will overflow to the four grids through the infiltration wood block, completing the filtration again.
Basically, every household can filter out a small part of the insect eggs by stopping at the third pool. The fourth step is not superfluous, but waiting for the insect eggs in the third pool to grow.
The smallest bacteria known in the world are larger than 0.1 microns. Insect eggs can grow from bacteria in just two or three days.
Since it's so big, since there's no way to filter it, you can just wait until it grows a bit bigger before filtering it. Of course, some people say that you might as well filter the red nematodes directly, then catch the old worms to eat the grown eggs inside. This method is also possible, but... it's extremely slow. Putting the old worms here only serves a cleaning purpose.
"Every day, we have to catch the old worms and put them in the third and fourth pools, and clean out the grown eggs."
There will naturally be some fish that slip through the net in the fourth grid, but you can put some vegetable roots on the top of the pond, and half of the insect eggs will be attracted there. When they grow up, the old insects can eat them.
This is actually also called the pig-raising flow, wait until you grow up...
Open a drainage hole in the middle of the fourth grid, and the filtered water will flow into it.
Opening a drainage hole in the middle helps the sediment sink to the bottom, and the insect eggs above are on the leaves. The water in the middle is filtered well and basically meets the water quality requirements for growing vegetables.
This type of filtration has existed since the Chongzhen period of the Ming Dynasty, but someone in the previous life improved it and found that this concave pool is really easy to use. One ring is connected to another, and it is the most efficient method, much more powerful than single filtration.
"Mom, the downside of this pool is that it filters slowly. It'll probably take a whole day to filter a whole pool of water. But the water from one pool is enough for you to use for irrigation, right?"
"Enough is enough. My daughter is just not good at studying. Everything else is fine."
After teaching Jingma the principle, the management office finally did not cut off the water supply for the next few days.
A new batch of vegetables began to be planted. Jingshu had a hunch that Jingma would definitely set a good example for Wucheng this time.
While the other twelve companies were cultivating simple mushrooms, only Jingma's development zone was unique in using this traditional method to filter out water and grow crops. Although the efficiency was a bit slow, it was still a great achievement.
When it comes to the food of ordinary people, it has also improved in recent days.
Although the government could not grow other crops, it was not short of water and was able to cultivate the first batch of mushrooms full of insect eggs.
It looks scary.
The white insect eggs on the layers of mushrooms are all like black heads growing in the mushrooms. After being cooked by the aunt in the cafeteria, they feel chewy in the mouth. When you bite them hard, it feels like something explodes or you’re eating fish roe.
Boiled mushroom eggs, 0.2 virtual coins per portion, add some batter, 0.5 virtual coins.
But if you vote for Zhao Shupi to be the allocation director through big data, you will get a free bowl of porridge.
Zhao Shupi became famous in the Banana Community for a while and gained a lot of attention. From time to time, people would line up at the noodle soup window, casting a vote and receiving a noodle soup.
Wang Qiqi borrowed 500 virtual coins from everywhere and gave them to Jingshu that day: "How can I maximize my profits with 500 virtual coins?"
