I will plant a field in the last days

To solve the root cause of the eggs, currently the eggs can only be filtered out through a filtration system, but the embarrassing thing is that they are all flooded.

This matter would really not be a problem before the end of the world. A batch of ultrafiltration equipment could be manufactured immediately. Every household in the United States has direct drinking water. It has been filtered in factories for a long time. It would not even be a problem in the United States.

But now it is very difficult to produce these equipment, especially some precision accessories, because the raw materials are really hard to find. Let’s say that the filter equipment and the filter element are not produced together, but the raw materials needed to produce a piece of equipment are There are hundreds and thousands more.

So we can only talk about salvaging previously produced equipment.

But there are only so many equipments, and there are too many monks and not enough meat. In the early days, it was okay for people to drink insect egg water. But when a large number of evolved insect eggs appear in the near future, drinking this water will cause stomachaches every day, all kinds of diarrhea, and dehydration.

At least there were lumps on the ground before, but after that it was just puddles on the ground. Ugh. I heard in the news that it is the result of a reaction between bacteria and the intestines and stomach, just like eating bad food will cause diarrhea.

At that time, whether it is the ultrafiltration system or mineral water, it will still become extremely precious. If you have the conditions, you will get incomparable comfort. If you don't have the conditions, you can only endure it.

After all, someone was smart and tried various methods, and finally was able to filter out some of the eggs.

"Mom, if the filtration system can filter out insect eggs, our ancestors' method can also filter out insect eggs."

Jing Shu said slowly.

"What can we do? Our filter cannot be installed. The little water we filter every day is not enough to water so many vegetables."

"You said it's something else? Oh, many people have tried filtration methods for survival in the wild, but that kind of filtration does not clean the eggs and does not meet the requirements. I heard researchers say that the eggs are invisible bacteria, such tiny bacteria Can it be filtered out?”

In addition to ultrafiltration, what other ways to kill insect eggs has become the hottest topic recently. Just look at Zhu Chuangshi. He came up with that method. Not only was he interviewed by the TV station, but he also became an Internet celebrity in China. Now every day He was invited to get rid of the pests, but Zhu Chuangshi's method could not cure the problem and was difficult to promote.

Then there are ultraviolet disinfection, chemical disinfection, etc., which can remove part of the insect eggs, but the remaining eggs can still be eaten by the crops and will not germinate.

"Come on, come with me to the back mountain to find materials. I'll give you a try at work tomorrow." Jing Shu said mysteriously.

Jing Ma doesn’t believe it. Now that technology is so advanced, what use can the ancient methods be used? Definitely not up to the standard of drinking water.

The standard will definitely not be met, but as long as we can grow crops in a different way, wouldn't it be enough?

Jingshu took Jing's mother and rummaged through the back mountain for an afternoon, picking up all kinds of minerals and stones, even yellow mud.

After pulling a whole cart full of things, at four o'clock the next morning, Jingshu was pulled up to go to work by Jing's mother who was eager to try.

Jingshu first wrapped the soil with cloth at the faucet in order of large, medium and small. After three layers of screening, the water penetrated 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 grid contains a pool of large stones, large pebbles, small pebbles, rubble, fine sand, and yellow mud. After water settles, it flows into the second grid of pools made of bricks, which are composed of charcoal and fine sand.

Jing Ma was hesitant to speak. This method had been used before, but the result seemed not to be ideal?

However, at this step, the basic filtration has indeed been completed. The third compartment is a large pool for storing water. There is a wooden plug in the upper part. When the water is filled, it will overflow to the four compartments through the permeable wooden blocks, and the filtration is completed again.

Every household basically stops at the third pond to filter out less than half of the eggs. The fourth step is not superfluous, but is waiting for the eggs in the third pond to grow up.

The smallest known bacteria in the world are larger than 0.1 microns. The eggs will grow from bacteria in just two or three days, so since there is no condition for filtration, you can wait until they grow up and then filter them. Of course, some people say that you might as well filter the red worms directly, and then catch the old worms and eat the eggs that have grown up inside. This method is also possible, but... it is not as slow as usual. Putting the old worms here only has the effect of A cleaning effect.

"Every day, we have to catch old insects and put them into the third and fourth pools, and clean up the eggs that have grown up in them."

There will naturally be fish that slip through the net in the fourth grid, but you can release pieces of vegetable roots on the top of the pond, and half of the eggs will be attracted there. When they grow up, the old insects can eat them.

This is actually also called pig breeding. Wait until you grow up.

Open a drainage hole in the middle of the fourth grid, and the filtered water will flow to the fifth grid.

Opening a drainage hole in the middle will help the sediment settle at the bottom, and the insect eggs on the top will be on the vegetable leaves. The water in the middle is filtered well and is basically suitable for growing vegetables.

This kind of filtration existed during the Chongzhen period of the Ming Dynasty. However, someone improved it in the previous life and found that this kind of concave pool is really easy to use. One ring is connected to another, and the rings are interlocking. It is the most efficient one. This method is much more powerful than filtering alone.

"Mom, the disadvantage of this pond is that it is slow to filter. It takes a day to filter one pond of water, but the filtered water in one pond is enough for you to water, right?"

"That's enough, that's enough. My daughter is just not good at studying, but she is good at everything else."

After teaching Jingma the principle, the management department finally did not cut off the water supply in the next few days.

A new batch of vegetables has been planted, and Jingshu has a hunch that Jingma will definitely set a good example for Wucheng this time.

While the other twelve divisions cultivated simple mushrooms, only Jingma's development zone uniquely used this indigenous method to filter water and grow crops. Although the efficiency was a bit slow, it was a great achievement.

Speaking of food for ordinary people, it has also improved in recent days.

Although the government could not grow other crops, there was no shortage of water, and the first batch of mushrooms full of insect eggs were cultivated.

It looks scary.

The layers of mushrooms are all white with insect eggs, which are like blackheads growing in the mushrooms. After being cooked by the aunt in the cafeteria, the mushrooms feel bouncey when you eat them. It feels like an explosion when you bite it hard. , the feeling of eating fish roe.

Mushrooms and boiled insect eggs cost 0.2 virtual coins each, add some batter and cost 0.5 virtual coins.

But if you vote for Zhao Shupi as the distribution director through big data, you will get a free serving of batter.

For a time, Zhao Shupi became famous in the Banana Community and gained a lot of attention. From time to time, he would see people queuing up at the dough window to vote and receive a dough.

On the same day, Wang Qiqi used 500 virtual coins borrowed from various places to give to Jing Shu: "How to use 500 virtual coins to maximize the benefits?"

There’s a third update, but it’s probably midnight, so I have to code it out before going to bed today.
