Su Daji returned to her home and locked herself in the house, she was a top student in Qingbei in her previous life. She needs to recall the principles of irrigation technology, and whether it can be realized in combination with the current society.

The principle of drip irrigation technology is to use a special irrigator, dripper or drip irrigation belt to make the water flow into the moist soil of the crop root zone in the form of water droplets.

Drip irrigation technology requires a high level of management of the irrigation system to ensure uniform irrigation in order to maximize the potential.

However, now, there is no irrigator at all, and the prerequisite for the normal operation of the irrigation system is that the pressure of the capillary inlet is not lower than 8 meters of head, so as to ensure relatively uniform irrigation.

Nowadays, it is difficult to transport water to the fields, even if even if even irrigation is not guaranteed. The only way is to dig a well!

Find a common area in the field and dig a well. The pump can't be made, so you have to use a bucket to get water. Although it will be tiring, it is undoubtedly a great boost for people now.

"The fields in Jizhou are not too far from the moat, so there is definitely a water source underground!"

Thinking of this, Daji hurriedly came to Su Hu's room. Seeing that Su Hu was frowning, he was discussing something with Su Quanzhong.

"Daddy, my daughter has something to say."

Seeing Daji running in in a hurry, Su Hu frowned and asked, "What kind of system is the girl's family like this?"

Daji stuck out her tongue, but didn't care. Sitting next to Su Quanzhong, he took a sip of tea and said breathlessly.

"Father, do you know about the drought in Jizhou this year?"

Su Hu nodded, he was worried about this matter. This year's drought is more severe, and there is not a drop of rain, which is likely to lead to no harvest after autumn.

"You know, isn't this because my father is discussing with your brother and preparing to open a warehouse to release grain."

Daji smiled and said, "You don't have to open a warehouse to release grain!" The daughter has a way to ask for water! ”

Su Hu was stunned for a moment after hearing this, in this era, asking for water is asking for rain. This is all for warlocks, Daji will ask for rain?

"Daji, don't you talk nonsense, you will beg for rain?"

Su Quanzhong was also very surprised, he knew that his sister liked to study some gadgets, but how could Daji do such a thing as asking for rain?

"It's not rain! It's asking for water! ”

"Asking for water?" Su Hu was even more confused, is this any different?

"Sister, don't sell it, hurry up and tell your father, what do you mean?" Su Quanzhong asked anxiously.

Daji cleared her throat and said, "When I say asking for water, I mean water from the ground."

"We have a lot of water under this land, and now that there is a big drought in Jizhou, we will send people to dig down from the fields, and we will definitely dig out the water."

Daji's words were amazing, and what she said was too unbelievable.

"Groundwater? How is this possible? Daji, don't lie to your father! ”

Su Hu couldn't understand, this ground is all soil, how could there be water?

Daji knows that explanations don't make sense, and facts speak louder than words. Only by digging out the water will Su Hu believe it.

"Daddy, you believe me once, what if you really dig out the water? We don't have to open a warehouse to release grain, and we can have a good harvest in the autumn harvest. ”

Daji's words really moved Su Hu, and now, he can only be a dead horse as a live horse doctor.

"Well, how many people do you need for the Father to believe in you?"

Daji thought about it, and now there are not so many tools for future generations, so she can only dig by manpower little by little, and she needs more than a hundred soldiers.

"Daddy, just wait for my good news!"

After speaking, Daji led the more than 100 soldiers and walked towards the field.

"Daddy, Daji, she... Can you really dig up water? ”

Su Quanzhong still didn't believe it, how could there be water underground? Su Hu shook his head, he couldn't believe it, but out of trust in his child, he had a trace of expectation.

The 100 soldiers, divided into five groups and a group of 20 people, dug in rotation day and night.

One day passed, two days passed, three days passed.

The soldiers sweated like rain under the scorching sun. None of them believed that water could be dug out of the ground, and now they had dug ten meters deeper.

Looking at the weak soldiers, Daji also muttered in her heart. Could it be that there is no water underground? But Jizhou City has a moat, and there is definitely water underground!

"Soldiers! Whoever digs out the water first, I will reward him with 5 acres of fertile land! ”

Daji's words are definitely a dose of stimulant, 5 acres of fertile land, that can feed five families. In an instant, he became a landlord-like existence.

These soldiers dug down as hard as if they had been beaten with chicken blood. Finally, on the seventh day, a soldier suddenly shouted!

"Water! Water! There's really water! ”

When Daji heard this, she hurriedly ran to watch. I saw that in the huge deep pit, there was a place that became particularly damp. The other soldiers began to dig hard into the damp area, and suddenly a cool jet of water gushed out.

Then, as if it could not be contained, it spread to the entire deep pit. The soldiers' clothes were wet, but they didn't care, dancing and shouting.

Daji showed a smile of relief, and sure enough, the hard work paid off, and the well water really let herself dig out.

"Go and tell Master Hou the good news!"

An officer shouted, and a soldier covered in mud quickly ran towards the Su Mansion. Go and report the news now, Hou Ye will definitely reward himself.

At this time, Su Hu was making preparations with both hands, and he mobilized all the surplus grain in Jizhou to prepare for this drought. Just as he was looking sad, a soldier covered in mud ran in.

"Master Hou! Master Hou! Water! Water! ”

Su Hu frowned and scolded angrily, "What water? Why did you run in with such filth? ”

"No, it's Miss! Miss dug out the water! ”

Su Hu stood up from his seat and looked at the person in disbelief.

"What do you say? You repeat? ”

"Master Hou, we dug water out of the ground! Mademoiselle is right, there really is water underground! Lots and lots of water! ”

Su Hu didn't care about any appearance at this time, the shoes on the boat, got on the horse and ran to the field.

When I came to the field, the water around this place was already surrounded by the people. And the innermost circle was surrounded by soldiers, and no one could get in.

"Get out of the way, Master Hou is here!"

The people seemed to be riding their horses and taking the initiative to give way to a road. Su Hu couldn't care about the people's worship of him, so he got off the horse and ran straight towards the deep pit.

The pit is half-filled, and it can't be stopped. Su Hu stared at all this blankly.

"Miracle! What a miracle! Su Hu muttered in his mouth.

Su Quanzhong also rushed over when he heard the inquiry, and when he saw this scene, he was even more dumbfounded. I didn't expect that there was really water underground, and Daji actually dug up the water.

"God bless me with my great business! God bless me Jizhou! ”

Su Hu knelt on the ground and shouted to the sky. These days have been very sad because of the drought. Now that water has been dug up from the ground, the drought problem has been completely solved.
