After a simple breakfast, the father and son each took a military green water bottle and went out!
Rural people usually work in the morning and evening and avoid the noon!
After all, it is relatively cool in the morning. If the sun rises, the temperature will rise rapidly.
In this unobstructed place, the scorching sun makes the fields look like steamers. It feels so sour and refreshing!
Zhou Yang first asked his father to take him to the original well in the village!
Since water has flowed there before, this means there is a water vein nearby.
Now even if the water table drops, that's where the best hope is to dig water out again.
But when Zhou Yang came to the dry well, he found that it had been severely damaged.
"Dad, what's going on? Are you digging down the well again?" Zhou Yang asked with a frown.
"Well, the technicians from the county said that if we dig down the original well, water is likely to come out, so we dug down more than ten meters again!"
"The results of it?"
Zhou Yawen sighed and said: "But no one expected that there is a thick layer of rock under the well, which is impossible to dig through!"
Zhou Yang picked up two small stones from the side of the well and threw them into the well. After a while, he heard a "dong" sound.
Based on the speed at which the stone fell, Zhou Yang quickly calculated that the depth of the well should be about 30 meters.
Based on the sound coming from below, it can basically be judged that there is still some water below, but the amount of water is very small.
If there is no water at all, the sound of the stone falling to the ground should be "bah", not "dong"!
"Are you disappointed?" Zhou Yawen said looking at his son.
However, Zhou Yang smiled and said: "No, I have basically confirmed two things through this well!"
"Those two?" Zhou Yawen asked curiously.
"The first thing is that there is groundwater here, and the second thing is that the water level of the groundwater here is relatively deep, and there may be a thick rock layer between the shallow water and the deep groundwater!" Zhou Yang said.
"Can the water shortage problem be solved?"
Zhou Yawen doesn't particularly understand these professional issues, nor does he care much. What he is most concerned about now is whether the water shortage problem in the village can be solved!
Zhou Yang immediately said: "If it's just a problem of everyone's drinking water, I don't think it's a big problem, but if you want to completely change the status quo here, it's not enough!"
Looking at his father's puzzled expression, Zhou Yang immediately said: "Dad, the biggest problem at Dongquan Farm right now is not the lack of food water. If it is just domestic water, what the soldiers send every day is barely enough!"
"Actually, what you are short of is agricultural irrigation water. Only by solving this problem can your crops on thousands of acres of land have a chance to be saved, and Dongquan Farm can be completely revitalized!"
Zhou Yawen frowned and said, "Agricultural irrigation? Are you planning to dig a deep well?"
"Well! I walked around the crop fields in the morning, and I think that for these crops, if there is enough water, at most three deep wells can save them!"
"This... Let's not talk about whether there is really deep underground water here. Even if there is, there may not be anyone in Hua County who knows how to dig a deep well!" Zhou Yawen said.
"Ignore this for now. Our task today is to see if this place is suitable for digging a deep well!"
"What do you think?"
"Look at the terrain!"
Zhou Yang didn't explain much, and then asked his father to accompany him and walked around the village.
In the morning, the two walked eastward for almost five kilometers before returning the same way.
Before half past ten, the two returned to the village.
While waiting for dinner, Zhou Yang found a place under the shade of a tree and started drawing.
After eating an unpalatable lunch, I simply squinted for a while.
When the sun was no longer so poisonous in the afternoon, the two set off again.
This time they first walked three kilometers north along the village, and then turned back west.
Every time he went to a place, Zhou Yang had to observe the terrain, soil, and vegetation in detail. When he encountered some special places, he would draw pictures on the spot, which made Zhou Yawen stunned.
At eight o'clock in the evening, the father and son finally returned from the south of the village after nightfall.
........
Returning to the shack where his parents lived, Zhou Yang didn't bother to eat, so he immediately took out the topographic map he drew along the way today and analyzed it.
Regarding how to explore groundwater, Zhou Yang can be considered a semi-expert.
Although he is not as good as those real geological experts, ordinary people are really not as good as him.
On the one hand, it was because Zhou Yang had several friends in his previous life who were famous geological experts in China, and he also learned a lot under the influence.
Secondly, in his previous life, Zhou Yang was sent to the northwest region many times to lead scientific research work, and he also personally participated in several projects to find water and dig wells, so he was quite experienced in this area.
In fact, if conditions permit, you can directly use a groundwater detector to detect it.
Although there are not many units of this device in China at the moment, the principle is very simple, which is inferred by the good conductivity of water and the difference in resistivity of dry and wet soil.
As long as he has the corresponding materials and parts, Zhou Yang can make it himself.
Compared with manual analysis, groundwater detectors are the most convenient and economical method of finding water, and their accuracy is very high.
It's just that there's nothing you want here. It's really difficult to get a groundwater detector.
Therefore, Zhou Yang could only use the old method to find water.
Under normal circumstances, there are three simplest ways to find groundwater. One is to look at the terrain, the other is to look at surface plants, and the third is to observe through climate.
For example, if there is a hole between two mountains, there will be no water in the middle; if there is a ditch between two mountains, there will be water flowing beside the ditch!
For another example, in places where the ground often fogs up in winter, the groundwater level is relatively shallow and is more suitable for drilling wells.
As long as you find the rules and methods, it is not difficult to find groundwater.
Today, Zhou Yang, accompanied by his father, walked through the area of several kilometers around Dongquan Farm, and he really discovered that groundwater may exist in many places.
In particular, there is a ditch between the east slope and the north slope. The ditch is very deep and there should be water as expected.
In addition, there is a piece of red land in the south of the village. The surrounding vegetation is sparse and there is not much grass. However, Zhou Yang found that there are many tall trees here, which is quite abnormal.
Therefore, he marked all these places one by one.
At the end of the day, Zhou Yang drew more than ten topographic maps on the manuscript paper he carried with him, all of which were places where he thought there might be groundwater.
As far as today's exploration results are concerned, Zhou Yang is still very satisfied.
When he finished sorting out all the information, it was almost nine o'clock.
After several urgings from Li Youwei and his mother, he ate something to fill his stomach, and then asked his father to take him to see the leader of Dongquan Farm.
Zhou Yawen was also shocked by his son's performance today. He originally thought that Zhou Yang was just a whim and didn't have much hope for him.
Although he also knew that his son had read many books since he was very young and was a famous child prodigy in the capital.
However, having a specialization in the field does not mean that reading more books will be useful, especially when it comes to some professional matters.
Moreover, my son was still a teenager when he went to work in the countryside and had not had time to go to college for further studies. How could he know how to look for groundwater?
However, at the end of the day, he realized that he really underestimated his son.
Apart from anything else, the topographic maps he drew impressed him with admiration.
Although Zhou Yawen was engaged in chemistry and did not understand geological exploration, he could still tell whether his son was drawing blindly.
Now that he said he was going to meet the leader of the farm, there must be something going on.
At the moment, he didn't say anything more and took Zhou Yang and the half-baked pig head directly to the farm management office.
