Chapter 42 Natural energy is coming (please vote for support!!)
Half a month later, it will be early August. Jinta County, salt-alkali flat construction site.
Lao Xiang is training five new employees of Alfalfa.
“The soil salt composition in the project area is mainly chloride, accompanied by sulfate or dehydrated gypsum, indicating that the project area is mainly saline soil rather than alkaline soil.”
“This type of saline soil has The strong collapsibility and salt expansion pose a great threat to the quality stability of roads and irrigation and drainage projects in the project area.”
"So the field roads need to use gravel pavement and gravel cushion; the production roads need to use plain soil pavement."
The newly arrived employees responded repeatedly, but they were all a little absent-minded and looked to the side from time to time. .
There were several large excavators digging deep into the soil back and forth, and the roar of their motors was deafening.
No matter how obsessed with excavators a man can be, no man can resist the temptation of an excavator.
You give him an excavator and he can look at it for a whole day.
As for why it is an excavator, not a deep cultivator or deep plow to turn over the soil.
This has to mention the experiences that made several major construction companies extremely sad.
Because the soil is too hard, and various hard rocks and pebbles appear from time to time in the soil, the blades of deep plows and subsoilers are often broken within a short time of operation.
Domestic machinery lacks power and the quality of accessories is also lacking. However, as veterans of land reclamation in Xinjiang Province and Long Province, they do not believe in evil!
Even if the engine emits black smoke, you must hold on to the plow.
It was not until the transmission shafts and beams of tractors were forcibly broken one after another that the stubborn farming unit finally took the lead in using excavators to dig up the soil.
Seeing that the young men's attention was attracted by the excavator, Lao Xiang felt a little helpless. Today's young men are not willing to learn theoretical knowledge.
But he still stepped forward and pointed at the excavator’s dutiful teaching:
“Deep plowing can loosen the tillage layer of the soil, break up the bottom layer of the plow, reduce capillary action, and improve Soil water permeability and water retention performance. ”
“Therefore, deep plowing of saline-alkali soil can accelerate the leaching of salts from the soil, inhibit the evaporation of soil water and groundwater, and prevent the upward movement of bottom salts to cause surface salt accumulation. ”< br>
I saw that the newly arrived technicians were listening carefully this time, and from time to time they compared and thought against the issued construction technical plans.
Lao Xiang just laughed.
The alfalfa saline-alkali land treatment plan is mainly carried out by the Planning and Design Institute of the Ministry of Agriculture for exploration and design.
But in the specific implementation of the technical plan, he made many major adjustments in accordance with Guo Yang's instructions.
To be honest, even he sometimes can't understand Guo Yang's thoughts.
After adjusting the plan, the progress of the project has indeed been greatly accelerated, but the expected quality of treatment has worsened!
It’s no wonder that Dr. Zhou and others from the Planning and Design Institute complained to the ministry, causing a stir. Many other provinces and cities have successively inquired about the Alfalfa project through various channels.
As a result, the province and city have sent people down many times to investigate, and everyone can see the concerns expressed.
Fortunately, all the project advance payments of Alfalfa were paid on time, and there were no abnormalities in the special funds in the supervision account.
This dispelled the concerns of the province and city, and the construction of the irrigation canal system gradually got on the right track.
In the plan adjusted by Lao Xiang in accordance with Guo Yang's instructions, mechanical desalination is required in the early stages of project implementation.
Use an excavator to scrape the salt layer within 10cm of the ground surface, peel off the salt crust, and then bury it deeply in a fixed area.
The advantage of this is that it can save water resources and achieve the purpose of improving the flushing effect.
After mechanical desalination, in order to meet the needs of mechanized grass planting operations, irrigation, salt washing and other technical measures, the terrain of the project area needs to be reshaped and leveled. The flatness requirement is to have a height difference of less than ±5cm.
At the same time, Guo Yang requested that during the land leveling process, the deep gray-blue potential reducing soil layer should be avoided from being dug out.
However, in Dr. Zhou's plan, this kind of soil layer with greater harm needs to be replaced with soil for treatment. After all, there are not many such extremely saline-alkali lands.
However, Guo Yang made adjustments to this, and also emphasized that this kind of land would be handed over to the ‘Alfalfa No. 1’ two years later.
Dr. Zhou and others were filled with resentment.
After the land is leveled, the entire flat field is plowed 30cm deep and exposed to the sun. Then comes the sand covering.
Jinta County is located between the Badain Jaran Desert and the Kumtag Desert. Pure quicksand sand beams can be selected as the sand source, and the cost of sand extraction is relatively low.
According to the soil depth required for the growth of alfalfa, the project area needs to be evenly covered with sand by 20cm and deeply plowed by 30cm, so that the soil in the cultivated layer is mixed at a ratio of approximately 1:3 to increase soil porosity and prevent Return salt and increase the dispersion flow of soil salt.
After sampling tests, the salt content of the surface soil has actually been reduced to a level that will not harm the growth of alfalfa!
This surprised Xiang Tianshan!
It also made him a little confused. How did Guo Yang know that covering 20cm of sand can inhibit salinity? It’s exactly 20cm!
Generally speaking, the governance projects are moving in a good direction.
The only thing that worries Xiang Tianshan is ‘Alfalfa No. 1’. In a year or two, will it really be able to conquer the heavy salt soil in the 30-100cm range of the middle and lower layers as Guo Yang wishes?
You must know that salt will flow upward with groundwater.
If not, this salt flat, which has cost a lot of money to transform, may once again face salinization year by year.
……
Jiuquan City, in the office building rented by Luhe Company.
“Hahaha...”
The unbridled laughter came from the office, making the employees of Haohe look sideways.
The newly hired front desk girl asked curiously in the office of the administrative department: "Sister Wan, do you think Mr. Guo has encountered some happy event, and he is smiling so happily."
"Then who knows, since I joined Haohe, I have never seen the boss smile. He has a straight face every day." Sister Wan is a young woman with exquisite make-up who is sorting information at the table.
"Why? Don't Guo always like to laugh?"
"Xiao Zhao, you idiot, can't you hear the boss laughing so loudly?"
Sister Wan scolded sentence, and then pointed upward mysteriously with his hand and said: "I heard from my family that some time ago, the city, province and higher authorities all expressed dissatisfaction with Mr. Guo's change of construction technology plan."
Xiao Zhao was stunned for a moment, then said: "Sister Wan, which company is upstairs?"
Sister Wan covered her pretty face in pain.
"Ding, natural energy +1."
In the office, Guo Yang looked at the message from the seed store and couldn't restrain his joy.
After being busy for so long, when I traveled back in time, I almost always revolved around the seed store and natural energy.
In my previous life, I was just an ordinary farmer, but after I came back from time travel, my stall was too big at first.
Five hundred million, two hundred thousand acres of saline-alkali land, government leaders at all levels.
The pressure was so intense that he almost couldn't breathe. He didn't dare to stop all the time. He was thinking about how to do the project every second.
He originally thought that he would have to wait until this season's alfalfa seeds germinate before natural energy could begin to accumulate.
Unexpectedly, half a month after the saline-alkali land treatment construction, there was news from the seed store.
Although there is only a little bit of natural energy, it represents a completely different meaning
You must know that at this time, in addition to completing the scraping of all surface salt layers, the project area was also deeply plowed and dried. It just started not long ago, and it was only yesterday that we started importing materials for sand covering.
At this moment, another notification sound came from the seed store.
"Ding ding ding... natural energy +1...+1...+1..."
It took a while to stop.
Guo Yang took a closer look and saw that the natural energy was: 18 points.
"Hahaha..." The hearty laughter spread throughout the entire floor.
