Mojia experiments Tanaka.

The bottom of the iron rod was a cylinder one and a half feet long and half a foot in diameter, and the bottom of the cylinder seemed to have been cut off in half obliquely by a sharp weapon, leaving a pointed head.

This is a common tool for digging wells and lifting soil in the rural areas of later generations, and Merton drew the drawings, and the skilled craftsmen of Mojia Village easily created them.

Mo Da held two thick wooden sticks with his arms, and the two ends of the thick hemp rope were tied to the middle of the sticks. The hemp rope wrapped around the iron rod over and over again, until it resisted the wooden rod, and the wooden stick was divided into four halves just right, each section was facing one direction, and a Mo family disciple held one end, so that a simple well-drilling tool had been completed.

"Hey!"

Under the command of Mo Da, the four Mo family disciples used the tip of the cylinder to use the power of a wooden stick to push it to the ground that had already been soaked, and again and again to fill the wet soil into the cylinder, and every time the cylinder was raised, a cylinder of soil could always be brought out.

Soon, a zhang long iron rod sank into the ground at a speed visible to the naked eye, and when the iron rod was submerged to the height of his chest, Mo Da picked up another iron rod one zhang long and connected it, pressed down, and repeated the steps of lifting the soil again.

"Out of the water!"

In ancient times, the water table was very high, and even now it is extremely dry, and when the first iron rod has just completely submerged into the soil, the soil that has been raised again has become a thin mud state, which is a sign of water.

After the water comes out, it has a certain effect on the soil, and the hardness of the soil is correspondingly much softer, and soon the second iron rod does not enter the ground, and the third iron rod is connected again.

It was not until the third iron rod was completely submerged in the ground that the drilling work gradually came to an end, and a deep well was completed in just half an hour.

Looking at the speed of drilling wells in Mojia Village, Fang Xuanling and Li Shimin were also dumbfounded, it was not an easy thing to dig a well in ancient times.

A good well should be dug first, and then a slope channel should be dug from the side to the ground, and it should not be too deep, too deep will be prone to lack of oxygen, and second, the water level in this era is very high, and it is impossible to dig from underwater.

After the water is discharged, the wall of the well is reinforced, and the channel through which the well is dug is carefully filled. It is impossible to get a well down in three or five days, and the well in front of me is dug in half an hour.

"That's it?" Li Shimin didn't care about the dirt all over the ground, and personally walked to the wellhead to look at the wellhead that was only half a foot wide, and couldn't help frowning, this well was really a little small, and it was impossible to put a bucket in.

Merton looked at the newly drilled well, nodded with satisfaction, and said, "Back to Your Majesty, this is just the first step, and the next step is to wash the well." ”

"Washing the well?" Fang Jun and Fang Xuanling looked at Merton dumbfounded, they had heard of washing hands, bathing, and washing clothes, but how to wash a well underground? As for Li Shimin, he has long been accustomed to the new words that pop out of his mouth from time to time.

"Uncle Fang doesn't know that there is a lot of mud in the water now, and if this soil is not cleaned out in time, it will block the water hole under the well, which is not conducive to the water coming out." Under Merton's explanation, the three of them suddenly realized.

"Then how can we get this muddy water out, such a small wellhead can't fit a wooden barrel at all." Fang Jun asked a question that Li Shimin had been entrenched in his heart for a long time.

Merton smiled mysteriously and said, "This is the most important thing in this experiment, Mojia Village will use a new tool to continuously draw water from this wellhead until the water in this well becomes clear." ”

Under the curious gaze of the three people, Mo Da quickly built the wellhead with blue bricks, and the two children of the Mo family carried two and a half zhang long iron pipes, and the other two carried a strange-looking iron guy with a long handle.

If someone is here in the future, they will definitely recognize it, this is the most common water intake tool in the eighties and nineties that has been eliminated in later generations - the well.

The two-zhang long iron pipe is put into the well, the upper end is connected with the bottom of the well, and it is simply sealed with soil, and then it is firmly fixed on the ground with a wooden wedge, and a pressure well has been made.

"Can this get out of the water?" Fang Xuanling couldn't understand what Merton was doing.

"One last step is needed." Merton took a gourd scoop from Moda's hand and poured the prepared water into the wellhead.

Fang Jun rolled up his sleeves, grabbed the handle of pressing the well, and pressed it one by one, this guy is powerful and powerful, this job is just right for him.

Within two or three clicks, under Fang Jun's regular pressure, a large stream of muddy water was discharged from the outlet of the pressure well, and gushed out along the ravines arranged in advance in Mojia Village, flowing to the hungry land.

"It's done!" Merton smiled contentedly.

Looking at the water mixed with the yellow mud, Li Shimin and Fang Xuanling did not have the slightest disgust, they reached out and took a handful of yellow mud water, looking at and feeling the coldness in the water, the ecstasy in their hearts could no longer be suppressed.

Yes, this method definitely works!

All the steps are unreservedly displayed in front of the eyes of the two, it is convenient to drill the well, and the material used to kill the well is iron, which is nothing more than a little more iron.

And it is manpower, for farmers, the most important thing is strength, as long as they can eat enough, it is worth the effort.

"The area that can be irrigated by a pressure well is about one acre of land, and if you add water diversion tools such as bamboo pipes and copper pipes, as long as it can meet the water needs of two acres of land. If a few more wells are drilled, as long as a family is not lazy, as long as it can ensure a bumper harvest of five or six acres of land every year. Merton said confidently.

"Six acres!" Li Shimin laughed, his mood was extremely joyful, the priority of drilling wells must be fertile land, and a family can have six acres of land to ensure harvest in drought and flood, that is, they can live in a disaster year.

The most terrifying thing about the disaster year is that there is no harvest, so that people can't survive.

"In a few years, when the experimental field of Mojia Village develops a good seed with a yield of six quintals per mu, the family will rely on six acres of fertile land to survive richly." Merton pointed to the Mo family's experimental field and said proudly.

"Good!"

Li Shimin and Fang Xuanling were so excited that they couldn't help themselves, if each household could be self-sufficient, and they would get three or four thousand catties of grain every year, unless they encountered a force majeure disaster, the arrival of the prosperous era of the Tang Dynasty was just around the corner.

Fang Xuanling looked at Merton with appreciation, and then looked at his son who was working hard to press the water, and couldn't help but sigh for a while, it was people who were more popular than people.

Fang Er was also speechless for a while, there were indeed many surprises with Merton, but the biggest disadvantage was that someone else's child was in front of him, and his sense of existence was almost zero.
