Chapter 170 Pollution
When Qiu Qiu and Xiao Han saw that the weather was stable and the water, soil and air could no longer smell the pungent smell, they led people to inspect and prepare for farming.
After Wen Wen knew about it, he called the research experts to join in. Qiu Qiu was eager to have dedicated people to do special things. If he didn't have space weapons, he wouldn't be able to deal with the pollution and mutations before.
Professor Zhang asked people to take some specimens back. He told everyone to wait for the test results to come out before touching the water source, soil, or even the plants.
Although the ecological environment seems to be much better after this heavy rain, no one knows whether there will be hidden crises.
Everyone agreed with Professor Zhang's view and suspended all activities. The children who had been depressed at home for a long time were detained at home again.
The adults and children could not go out, so they had to hide in the house. Zhao Huaihuaian was a teacher before, and it came into play at this moment. He found Gu Baoer and Zhao Xiaoguo as assistants, so that the children at the base gathered in the vacant yurts at the foot of the mountain to learn knowledge. .
Qiu Qiu went to listen once and felt that although Zhao Huaian only taught reading and arithmetic, Zhao Huaian's teaching methods were very humorous. The children especially liked listening and learned very seriously.
This is a good phenomenon. You must know that there are many blind children in their base, such as his glutinous rice balls and An Ning's Dudu. Before the apocalypse, they didn't even have time to go to kindergarten. Anping, Anxin, and Fengsheng were still born after the apocalypse. , not to mention.
For the sake of long-term planning, everyone agreed that the issue of education must also be addressed. Although children cannot now receive compulsory education like in peacetime, basic writing and arithmetic problems should always be learned.
For this reason, Qiu Qiu specially found Zhao Huai'an and discussed with him that if the test results came out and there were no problems, he would set up a school at the base and put him in charge of selecting suitable candidates among the base members to participate in the During teaching.
Zhao Huaian liked to teach and educate people, so Qiu Qiu's request was exactly what he wanted, and he happily agreed immediately.
The matter was settled like that. The children knew that soon the base would help them set up a school, and they became more active in going to school.
Because Teacher Zhao said that when the school is built, they will take a test, and they will be divided into classes according to their performance rankings. The children are also very strong and face-saving, and no one wants to fall behind others.
For this reason, the adults who were usually troubled by their children are now all idle, and each of them has become extremely uncomfortable. The family is extremely quiet, and they cannot go out to farm or engage in infrastructure construction.
So what to do now?After much deliberation, everyone can only focus on family planning.
Therefore, before the inspection report came out, the men and women at Qiuhan Base each devoted themselves to the "construction cause".
As for people like Qiu Qiu, Xiao Han and others, they can only focus on participating. They only suffer for those who have no partners. They are forced to listen to the corner day and night, and they are tortured both physically and mentally.
Fortunately, such days only lasted for half a month, and it was over when the test results came out.
The report shows that the "tritium element" in the water source has exceeded the standard, and the soil contains a large amount of heavy metal elements "cadmium", "strontium" and "cesium".
However, because a large area of mutated bluegrass was once planted in the lake, it absorbed most of the harmful substances, so the water pollution was relatively lighter compared to the soil.
This knot made everyone sweat. They couldn't imagine what would happen if humans lived in this environment for a long time.
After all, drinking water with excess tritium content will greatly increase the ability to destroy the stable structure of biological macromolecules, such as DNA, increase the risk of mutation, and seriously endanger biological health.
If humans eat food crops grown in soil containing radioactive cadmium for a long time, cadmium will accumulate in the human body, causing systemic neuralgia, joint pain, fractures, and even death.
There is also the element strontium. Excessive intake can lead to rapid bone growth and development, and symptoms such as joint enlargement and pain.
It interferes with the absorption and metabolism of calcium, causing symptoms of gastrointestinal indigestion, such as vomiting and diarrhea, seriously affecting bone development and growth, and causing abnormalities such as osteoporosis and rickets.
As for cesium, it is particularly strongly adsorbed in soil, and some plants can accumulate cesium.
Therefore, high concentrations of radioactive cesium can enter the human body through these plants and remain in soft tissues throughout the body, especially muscles.
This substance can cause chronic damage, acute radiation sickness, such as nausea, fatigue, vomiting and hair loss, and risks such as cancer.
Just thinking about these diseases makes everyone scared, but now, it is urgent to solve the problems of water source and soil pollution.
The water source is not bad. There is mutated bluegrass in Qiu Qiu's space. All he needs to do is take out a corresponding number of plants and plant them.
However, solving soil pollution is relatively troublesome. After all, there is no high technology, let alone too many chemicals and bluegrass juice to deal with large-scale land pollution.
Therefore, they can only use the most primitive method, planting a large number of plants, using their rhizome parts to absorb heavy metals in contaminated soil, and accumulate them in the upper part of the ground, and then harvest the above-ground parts of the plants to achieve the purpose of removing pollutants.
For this type of pollution, shepherd's purse, rapeseed and red amaranth are most suitable for planting in the soil.
As a cadmium-containing plant with rapid growth and large biomass, shepherd's purse not only absorbs an amazing amount of cadmium, but also has a strong ability to purify the land.
Someone once found that the higher the concentration of cadmium in the soil, the greater the amount of cadmium absorbed by shepherd's purse.
But in comparison, rapeseed has a better ability to purify cadmium-contaminated soil than shepherd's purse. Among them, "Xikou flower seeds" are the best. However, rapeseed is precious and cannot be used by any crops grown. Therefore, they cannot all grow it. , Therefore, shepherd's purse is also within the planting range.
The same applies to strontium and cesium contamination, but you need to choose red amaranth for planting crops.
Just wait until these crops are planted and reach the flowering or maturity stage, then harvest the plants or remove them entirely from the contaminated soil, and crush and burn them.
Afterwards, the next batch of plants can be planted again or multiple times depending on the severity of soil contamination, and so on until the inspection is qualified.
After the method was chosen, everyone immediately started taking action, because the crops used to evolve the soil were not edible, and no one was willing to waste too much rapeseed and red amaranth.
Therefore, Qiu Qiu divided some people to collect shepherd's purse seeds around the base, while the remaining ordinary residents of the base were divided into 4 teams with the soldiers and security team members, including Gui Lengtian, Liu Ning, Han Jie, and Chen Yanbing , specializing in rapeseed sowing, red amaranth, and mutant bluegrass planting.
Everyone wore long clothes and trousers, put on gloves, and covered the exposed skin as much as possible. They made sure again and again that they would not come into direct contact with contaminated water and soil before starting the farming plan.
The first step is to soak red amaranth and rapeseed seeds for germination. Soak the seeds in clean water for 24 hours, remove them and place them in a warm environment for germination.
The second step was to hoe and plow the ground. Since the base now has many agricultural machines, everyone didn't put much effort into it. All the land that could grow crops in the entire Qiuhan base was plowed by everyone.
Afterwards, everyone cleared out the grass roots, tree vines, and stones that were left in the soil and had not been completely corroded by the acid rain, and then dug the soil again.
As for the cleared grass roots, trees and vines, because they contained polluting elements, they were all transported outside the base and uniformly burned by researchers.
After thoroughly plowing the land, we began to apply base fertilizer, which we could only rely on the manure of poultry and livestock at the base. However, the land was wide and the base fertilizer was not enough, so we tried our best to apply it to the central area first.
After that, it is time to sow the seeds into the soil. Red amaranth and rapeseed are better to plant. Just broadcast them directly and cover them with a thin layer of soil.
However, the collection process of shepherd's purse seeds was not ideal. Due to the previous acid rain and black rain, a large number of outdoor plants mutated or were corroded and died. As a result, the base residents searched nearby for nearly half a month but could not find any. available seeds.
Everyone was a little discouraged, thinking that so many seeds would be wasted, and everyone felt distressed.
An Ning's heart started to bleed as she looked at the boxes of seeds being moved out of the warehouse. He frowned and looked at Qiu Qiu and Xiao Han, "I don't know how many crops need to be planted on the land in our base to purify the soil? It would be great if there were shepherd’s purse seeds! Even shepherd’s purse seedlings would do!?”
Qiu Qiu's heart suddenly moved, thinking of the deep mountains and wild forests in the space, and immediately stretched out his hand to pull Xiao Han's sleeve, "Brother Han!"
Xiao Han turned to look at him and quickly bent down to get closer, "What!"
Qiu Qiu approached him and whispered, "Do you think...there will be one there?"
Xiao Han's eyes suddenly became clearer because of his words, and then he nodded slightly, "Go in and have a look tonight!"
"Uh-huh!"
An Ning looked at the two of them gossiping, "Brother Qiu Qiu, what are you whispering to me?"
"I won't tell you!" Qiu Qiuchong raised his chin to Xu Lei, who was moving things, "Go find your husband!"
"I want to break up with you for one minute!"
An Ning rolled her eyes at him, turned around and ran to Xu Lei angrily, pointing at Qiu Qiu and Xiao Han. She didn't know what he said, but Xu Lei hugged him and whispered in his ear with a doting look on his face. After a few words, he immediately started to smile.
Qiu Qiu and Xiao Han looked at his childish look and couldn't help shaking their heads and laughing.
In the evening, as the sun set, the people at the base who had worked hard all day walked together in groups and returned to their respective camps.
Qiu Qiu and Xiao Han returned to Qiuhan Mountain. After dinner, they took their son back to the room early. Now Tang Yuan is 10 years old.
Now that he doesn't live in the same room as them, Qiu Qiu made a bed in the study, which has become Tangyuan's exclusive room.
The two of them stayed with their son in the room, stacking blocks, until he felt sleepy and wanted to go to bed, then they returned to his bedroom and entered the space.
Looking at the towering mountains in the distance, Qiu Qiu raised his chin and said, "Go directly into the mountains!"
"Ok!"
Xiao Han nodded, then put his arms around Qiu Qiu's waist. The two of them tapped their feet at the same time, and used the force to leap away. After a few leaps, they reached the foot of the mountain.
Letting go of the person in his arms, Xiao Han walked side by side with Qiu Qiu with awe and exploration of this mysterious place.
The vast expanse of empty wild forest surrounds the continuous mountains. It looks quiet and mysterious inside. The branches and leaves are gently instigated by the slight wind. Xiao Han is fascinated by the luxuriant grassland, various flowers and many unknown plants, herbs, etc. in the wild forest. etc. attracted attention.
"It's beautiful here!"
Xiao Han raised his toes and lightly tapped the purple flower on the side, "It's just a little hot!"
He suddenly turned to look at Qiu Qiu and said with a guilty look, "Last time you were there looking for medicine for me. You stayed there for so long. It was very hard, right!?"
"Fortunately!"
Qiu Qiu curled her lips at him, "It's worth it for you!"
Xiao Han looked at him, his eyes full of deep affection, "I will not let you get hurt again in the future!"
"it is good!"
Qiu Qiu nodded with a smile and mouthed towards the path ahead, "Let's go!"
The two set out on the road again, and not long after walking, they stopped in a low-lying area.
"so many!"
The two of them looked at the shepherd's purse field in front of them, which was about 30 to 40 centimeters high, green and with jagged or notched stems and leaves, and laughed so hard that they almost couldn't see their eyes.
Qiu Qiu took out a sickle and handed one to Xiao Han. The two immediately squatted down, carefully selected the over-old shepherd's purse, cut them all, and put them into the basket.
In less than half an hour, they had cut four large bamboo baskets full. Qiu Qiu carried the baskets containing shepherd's purse back to the front of the small building, and then laid a drying mat on the ground with Xiao Han. Then he took out the shepherd's purse and spread them one by one on the ground. Dry on top.
After going back and forth for several times, the two of them dried all the shepherd's purse cut in the forest. When the water evaporated, they rubbed the seeds out of the dried shepherd's purse with their bare hands, kicked up the ashes, and then the collection was completed.
However, the removed seeds need to be dried again. Usually, it only takes three days to dry, but only one day is enough in the space.
The two spent seven days repeatedly harvesting and drying shepherd's purse in the space, and finally collected more than half of the Haiwan's seeds.
Although these cannot be planted on many acres, the things produced in the space have a high reproduction rate and fast root movement. As long as they continue to collect and let everyone plant more crops, I believe that it won’t be long before the entire base will be covered with lush greenery. Shepherd's purse.
When Qiu Qiu took out the seeds and distributed them to each team for planting, everyone was shocked. Professor Zhang excitedly pinched a few seeds with his hands, held them close to his eyes and looked at them carefully for a long time, then looked at him and spoke with a trembling voice.
"With this, I believe our base will be fine soon!
When the yield increases in the future, we will get more seeds and let the soldiers walk around and sprinkle the seeds around. In this way, they will slowly spread. I believe that one day, everywhere we look will be green! "
"That would be great!"
She smiled softly and said excitedly, "Now I look at these strangely colored and strangely shaped plants all day long, and I feel scared in my heart!"
She looked at everyone with fear, "Fortunately, the thorns used for city defense in our base have not mutated.
Otherwise, just thinking about how we are surrounded by the black-smelling defense line of thorns every day makes me feel horrified! "
"Who said no!"
Everyone followed suit, but Qiu Qiu and Xiao Han looked at each other with a look of realization.
