The rise of nanometers

Xiao Yuan, the general manager of Fengmin Agriculture, saw the reports of various business groups in the past week. Currently, the contracted saline-alkali land totals only about 1,863 acres.

He also felt deeply helpless about this situation.

He could only ask Zhang Yaoguang, the manager of the agricultural machinery rental company, to detach a part of the desalination fleet and start transforming the contracted saline-alkali land.

Zhang Yaoguang also attached great importance to it. He hurriedly separated two groups of desalination convoys and personally led the people to prepare to transform farmers' saline-alkali lands.

Not far from the farmland in Zhangjia Village, there is a saline-alkali field with only sparse shrubs and weeds growing on it, and many areas are covered with bare sand.

When the convoy arrived at the saline-alkali land, the captain opened his laptop and pulled up a map of Zhangjiacun, on which farmland had been divided into pieces.

The areas marked in yellow are saline-alkali fields that have been contracted; the green areas are farmland that farmers are currently planting and utilizing; and the red areas are saline-alkali wastelands that have not been contracted.

Click on the yellow plot, and the data of which contracted farmer belongs will pop up.

Based on the remaining reference points on the land, such as field ravines, field lines, and stone boundary strips, several flags were quickly planted.

I called again and asked the farmers who signed the contract to come over and confirm again to avoid digging in the wrong place.

After a while, several farmers drove motorcycles or tricycles and arrived next to the saline-alkali wasteland.

Captain Li Guoli opened his voice and shouted: "Who is Zhang Youde?"

"I, what's the matter?" A dark-skinned middle-aged man raised his hands while trotting.

"Fellow, you have signed a contract for pasture cultivation, right?"

Zhang Youde nodded: "A few days ago, my eldest nephew said that fertilizer would be delivered, so I signed it. What is this for?"

"Now we need to change the saline-alkali land. Fellow fellow, please make sure whether this land is yours, so as not to make a mistake." Li Guoli pointed to the area surrounded by a dozen small flags not far away.

"That's right, this area belongs to my home."

"That's good." Li Guoli turned his head and shouted loudly: "There is nothing wrong with the place, let's start working."

"receive."

The excavator's diesel engine puffed out black smoke and plunged directly into the bucket.

Zhang Youde and others, who were watching the excitement not far away, were talking quietly, as if they didn't believe it.

Over the years, many experts have studied the improvement of saline-alkali soils and conducted many experiments. However, these experiments either cost too much, or they returned to the saline-alkali soil state after not being planted for several years.

Moreover, agricultural water in Shandong Province is quite tight. Traditional plans to improve saline-alkali soil usually require flushing with fresh water to wash away the saline-alkali components of the surface soil.

More than twenty minutes later, when a large area of ​​the land was excavated, the first batch of desalted soil and organic desalted soil was once again transported back to the pit by an earth-moving truck.

Two groups of desalination fleets worked together from morning to evening to complete the transformation of approximately 36 acres of saline-alkali land.

The team set up a tent and cooked and rested on the spot.

At the same time, based on the previous experience in transforming pastures, the soil after the transformation will lack saline and alkali components. After replacing some parts of the water supply truck, it became a sprinkler truck.

Prepare the saline-alkali water and spray it into the soil again to ensure that the soil does not lack saline-alkali components. For planting land, it is best to maintain a reasonable proportion of the respective elemental components, rather than beating them to death with a stick.

In March in the North China Plain, it was still cold and windy at night.

The more than 40 people in the fleet are powered by diesel-powered vehicles, and the water is very convenient. They put some directly from the circulating water pipe of the desalination vehicle. If it is water for drinking, the company has prepared trace element supplement tablets and throws pure water directly. Inside, it will become artificial mineral water.

When bathing, use an electric heating rod to boil water, and then take a bath in the desalination cabin of the desalination truck, because this will not waste water. When the desalination truck is operating tomorrow, the bath water will enter the water circulation system again.

Inside the tent, there are mandarin duck pots, tomato soup base, and spicy butter soup base on the electric stove. Their ingredients and daily necessities are guaranteed by special transport vehicles.

Four female employees working with the team (usually the wives of other team members) cut beef slices and beef louvers, and served fish balls, meatballs, mushrooms, cucumbers, etc.

Li Guoli started to use his chopsticks to cook the hot pot: "Come on, everyone, don't be polite, Mr. Zhang, don't be polite either."

"Haha, everyone, let's eat!" Zhang Yaoguang picked up a piece of beef and rolled it into the spicy pot. The beef was from old cows slaughtered by his company itself.

More than 40 people were divided into six tables and cooked hot pot in their respective tents.

This way of life may become their normal life, because the way the desalination fleet operates means that they cannot leave the transformation area at will. They will not move to the next area unless the transformation of the saline-alkali land in that area is completed.

For these employees, their wages are also quite high. They are basically junior level 3 technical workers. The basic salary starts at 6,000. With various subsidies and overtime pay for field work, the salary may reach tens of thousands every month.

The next day, it was dawn.

Everyone started working. The farmers who came yesterday were notified in advance and their land was determined. The transformation work was the same as yesterday.

Through a series of processes including excavation, screening, water injection, desalination, dehydration, soil mixing, and backfilling, acres and acres of saline-alkali land have been transformed into farmland that can be cultivated.

Those farmers also took one look and lost interest. They felt that this so-called saline-alkali wasteland transformation was very unreliable.

Zhang Yaoguang also sees the mentality of the farmers, but it is useless to explain this kind of thing blindly. Only by presenting the facts can the farmers be completely convinced.

In the entire Zhangjia Village, the contracted saline-alkali land area is only about 120 acres. With overtime work, all the transformation can be completed in about three days.

As for the Agricultural Doctor Company, the Lu Bao family brought the intern employees to Zhangjiacun.

"Mr. Zhang, is this the land that has been renovated?"

Zhang Yaoguang nodded and pointed to the laptop. Their farmland management system was used internally.

The contracted wasteland that has been transformed will change from the previous yellow to a green diagonal stripe. The small flag above represents the database link of each household. After the data fleet completes the transformation, the data must be uploaded in time.

After reading the system information, Lu Baojia turned around and said, "Wen Bin, you lead people to conduct a sampling survey, and also conduct a soil sampling for other farmland of the contracted farmers."

"no problem."

Qin Wenbin divided everyone into groups of three and brought soil drills, sample storage bottles, laptops, etc.

In the farmland management system, other basic farmland information of contracted farmers is also entered into the database.

In addition, now that spring has begun, many farmers are busy.

Based on relevant information and comparison with Beidou satellite positioning, we came to a farmland.

Zhang Youde, who had just plowed the farmland, was also very curious about what these children were doing. After looking and asking for more than ten minutes, he still felt confused.

Having done farm work all his life, he relied on experience when it came to farming. Now that he heard about pH, trace elements, humus, and microorganisms, he was really confused.

Qin Wenbin took eight soil samples in the field, each of which was divided into surface, middle and deep layers.

I also asked Zhang Youde what crops were grown on the land in previous years, and found that peanuts were grown in previous years. All these data need to be entered.

Because the more complete the data, the more complete and accurate the comprehensive assessment of soil will be.
