On May 9, Tian Xinmiao came to the electrical appliance factory at the invitation of Zhang Yongtai.

Tian Xinmiao doesn't know much about the production line of refrigerators and washing machines, but she is no stranger to the operating principles of refrigerators and washing machines.

After taking a general look at the production lines of refrigerators and washing machines, she focused on the refrigerators and washing machines produced by the electrical appliance factory.

The problem with the refrigerator is that the refrigeration effect is not good, and the problem with the washing machine is that it is noisy and weak when washing on the wheel.

Tian Xinmiao asked the technicians to disassemble the refrigerator and washing machine, tested the components one by one, and had a rough guess in his mind.

However, because he was not completely sure of the problem, Tian Xinmiao postponed the reply on the grounds of careful consideration.

On the 10th, after participating in the unusually smooth graduate interview after Cui Qinghui's obstruction, Tian Xinmiao began to pack his things in the afternoon.

When Ruan Haocheng came back from school in the afternoon, a string of followers followed.

As soon as he heard that Ruan Haocheng was going to take the graduate school entrance examination, Chen Zhiyun, who had already had another plan in his heart, also announced his decision to take the graduate school entrance examination.

Now the other two of the four people who are inseparable on weekdays are not calm.

With the excuse of discussing the postgraduate entrance examination with Ruan Haocheng and Chen Zhiyun, he followed Ruan Haocheng to dinner by the way.

After dinner, the four of them sat in the small living room and chattered for a while, and finally unanimously decided to take the graduate school entrance examination together.

asked Wu Yingjie for instructions, so that Ruan Haocheng went alone, they were not at ease, and in the end, Chen Zhiyun accompanied Ruan Haocheng to go together.

Tian Xinmiao, who was quite helpless, had to call Lu Zheng so that he could take Chen Zhiyun into account when arranging the vehicle.

At half past seven in the morning of the eleventh, Lu Zheng, Tian Xinmiao, Ruan Haocheng, Chen Zhiyun and his party set off.

At noon, after a short break, they continued on their way.

At about eight o'clock in the evening, they arrived at Kushan Town, near Kuta Farm.

There is a small military camp in the town, and there are about 200 people stationed in Lu Yun's jurisdiction to manage the farm.

Old Man Lu lived in a small courtyard house on the edge of the barracks that was exactly the same as the surrounding houses.

Lu Zheng took Tian Xinmiao and others straight to the courtyard.

Seeing Lu Zheng's old man Lu didn't give him a good face, but when he heard that Tian Xinmiao and others were experts he specially invited to solve the farm problem, Old Man Lu's face finally improved for him.

Because he was in a hurry, the next day, Tian Xinmiao entered the farm with Lu Yun, Lu Zheng and Old Man Lu, who had to follow.

Ruan Haocheng and Chen Zhiyun were sent to the base by Lu Zheng's driver.

Tian Xinmiao spent two days inspecting the soil and water sources.

As she had speculated, the farm's soil had become slightly salinized.

The reason for this is that there was a salt water ditch upstream of the lake, but when the local people expanded the land in order to reclaim the land, the flow of the salt water ditch was modified, so that the salt water mixed into the lake.

Because compared with the water body of the lake, the amount of salt water mixed with it is not too much, and it is not too obvious when it is usually drunk, and it has not attracted the attention of the water supply department.

After long-term irrigation with unfiltered lake water, the soil on the farm gradually became salinized.

The degree of salinization is not too serious at present, and the soil surface has not yet formed an obvious white plate, so Lu Yun and others did not think of going there.

After finding out the reason, Tian Xinmiao gave a set of treatment plans.

The first step is to modify the flow direction of the brine ditch.

In the second step, the water quality is treated on the way out of the lake to the farm.

In the third part, the treated water is used to flood irrigation-drainage-flood irrigation to repeat the soil for salt flooding and salt washing.
