"What if there is land far from the river?" After all, Fang Xuanling was the prime minister of the dynasty, and he asked the key to the problem. Close to the river, the maximum number of fields with conditional irrigation accounts for one-tenth, while land without water conservancy abounds. Those are the most important things that have historically been the focus of droughts.

In this era of official status, fields close to rivers for irrigation were considered high-class fields, and most of these high-class fields were controlled by families and landlords, who had deep family backgrounds and strong ability to resist natural disasters.

And every time the disaster is affected by the ordinary people, most of their land is barren middle and lower fields, most of them are far away from the river, not conducive to irrigation, or low-lying, not conducive to drainage, drought and flood can cause a large-scale reduction in the yield of the field, can only rely on the weather for food, they are the biggest victims of every natural disaster.

Merton understood Fang Xuanling's worries, thought about it and organized his language and said, "Uncle Fang, do you know that among our common water sources, in addition to rivers, there is also a place with a large number of water sources, which are ubiquitous and almost inexhaustible. ”

"Everywhere and inexhaustible?"

Is there one? Fang Xuanling felt that his brain was a little insufficient, if there was really such a place, why didn't he know, why didn't the people use it to irrigate.

Fang Xuanling looked at Merton suspiciously, but found that Merton's eyes were staring straight at his feet. Fang Xuanling had a flash of inspiration, and suddenly blurted out: "Well water? ”

Merton nodded and said, "Uncle Fang is wise, what the little nephew said is well water, but the Mo family calls it groundwater." ”

Merton remembered that in later generations, the overwhelming variety of wells, pumping groundwater for irrigation was the mainstream, and how many fields could be irrigated by river water alone?

"Groundwater? The water source beneath the surface of the earth is indeed very vivid! Fang Xuanling nodded, this kind of water source is indeed ubiquitous, and it is almost inexhaustible.

"I know the water from the well, but it is very difficult to dig a well, and it is almost impossible to irrigate the fields with buckets of water alone." Fang Xuanling's eyes dimmed instantly, although he found a water source, but this idea was impractical and unrealistic.

Fang Xuanling shook his head and said, "Uncle Fang, don't be in a hurry to deny it first. The experimental field in Mojia Village in the south of the city is a dry field, and the Mojia family is conducting an experiment to absorb groundwater. ”

Although the 100 acres of experimental fields in the south of Mojia Village are close to Chang'an City, they are indeed inferior fields, not to mention low yields, and they are far away from rivers and have no irrigation, otherwise Mojia Village would not be able to succeed easily.

"Oh!"

Fang Xuanling's eyes suddenly flashed, the Mo family's experimental field is famous in Chang'an City, especially when Mo Dun once promised to achieve a yield of six quintals per mu, many people are ready to see the Mo family's jokes, it is simply whimsical to want to achieve such a high yield in a low-grade field.

However, Fang Xuanling looked at Merton's confident face, and the doubts in his heart faded little by little, replaced by bursts of hope, if Merton can really solve the irrigation problem of inferior fields, then it is not impossible to produce six quintals per mu.

If this method can be promoted, it will be a blessing for the people of Guanzhong, and it will also be a blessing for the people of Datang.

Thinking of this, Fang Xuanling couldn't sit still anymore, and immediately pulled Merton and walked out.

"Oops! Why are you in such a hurry? Jun'er's friend has just arrived, so why don't you stay for a meal! As soon as Fang Xuanling pulled Morton out of the door, he saw a gentle and generous middle-aged lady coming towards him.

"Hello aunt!" Merton hurriedly saluted.

For the noble lady in front of him, Morton has been famous for a long time, and for the Lu family, who can train the prime minister of the current dynasty to be obedient and close, how can Morton not throw himself to the ground, the word jealousy originated from the one in front of him.

"Madam, don't eat yet! We've got something important to do! Fang Xuanling waved his hand and said, pulling Merton and rushing out of the door

"Mother, Merton is leaving, I'm going to see him off too!" Fang Jun came out of nowhere, and ran away with Merton.

"This kid!" Lu Shi looked at Fang Jun, who slipped away like a rabbit, and said hatefully, in the blink of an eye, the whole family was left with her to eat alone.

"What are you doing here?" Merton stared at Fang Jun angrily and said.

Fang Fu, as the prime minister's mansion of the current dynasty, of course there are many carriages, but Fang Jun came with a dead face, and he had to squeeze a carriage with Merton.

"Nonsense, you think I want to be at home by myself, if I'm at home today, my mother will definitely compare me to you for the whole lunch, and she can nag me for a day!" Fang Jun thought about his fierce mother, and couldn't help shrinking his head, and at the same time hated Merton, someone else's child.

"And it won't be boring to follow you Merton, the little brother has missed so many wonderful moments of Brother Mo, and this time he can't miss it."

Merton glanced at Fang Jun in surprise, he didn't expect this guy's dog nose to be so smart.

"What the hell can I tell my little brother first?" Fang Jun said impatiently.

Knowing his son Mo Ruo's father, Fang Jun certainly knows how calm his father is, and it must be a big deal to be able to make his father so impatient.

"You'll know when you get there!" Morton sold Guanzi, making Fang Junjun scream.

The urgent Fang Xuanling directly used the prime minister's line card to open the way, and traveled unhindered along the way, and it didn't take long to arrive at the South City Gate, and less than two miles out of the South City Gate was the Mo family's test field.

Outside the Mojia test field, there are still people buzzing.

Spring ploughing has passed, the sales boom of Quyuan plough has passed, but the sales of artificially hatched chickens, ducks and geese are still hot, plus the people of Chang'an City who have seen the ink magazine advertisement, have come to buy the new hydraulic overturner.

As soon as Fang Xuanling got off the carriage, he saw a row of five huge waterwheels neatly displayed next to the pool outside the experimental field of Mojia Village. This pond was originally a pond for transferring live fish in Mojia Village, but now it has all given way to waterwheels.

"Whoa!"

Two strong men in each waterwheel are stepping on the pedal of the waterwheel, and every time they exert force, a large amount of pool water will be drawn out of the pool.

The outlet of the waterwheel was tumbling and flowing, and the rushing water flowed around the pond for half a circle, and then flowed into the pond again.

"That's a lot of water!" The people of Chang'an City on the side exclaimed.

Compared with the traditional cylinder truck, the water output of the hydraulic dump is much larger, which also means that the efficiency of irrigation is much higher, and the price is relatively flat.

"This pond is a source of water, and if we don't re-flow the water, I'm afraid it will drain the pond in a day." Merton pointed to the waterwheel and explained to Fang Xuanling.

Fang Xuanling looked at the waterwheel in front of him with satisfaction, the advertisement of Mojia Village was not exaggerated, this waterwheel was indeed as advanced as it was advertised, easy to operate, and produced a large amount of water.

With this hydraulic rollover in front of Zhuyu, Fang Xuanling was even more excited about the tools that Merton said could draw groundwater.
