Hong Chengchou and Li Jie looked at Mao Wenlong one by one as if listening to the Arabian Nights. The yield of 5,000 catties of sweet potatoes per mu is an amazing yield.

In their cognition, there has never been anything like it. Hong Chengchou was the first to doubt the truth of what Mao Wenlong said, and asked in person: "Don't fool us, you kid, how can there be any crop yield per mu that can reach 5,000 catties in this world." What's more, if there are continuous disasters today, it is difficult to see even a single weed in the wasteland. ”

The rest immediately echoed it, saying that Mao Wenlong was lying!

Mao Wenlong was furious, these people completely regard ignorance as the truth, this world is so big, nothing has happened, and they are completely frogs at the bottom of the well.

There is nothing to say, seeing is believing, Mao Wenlong did not distinguish with them, signaled them to follow him, and then ordered someone to prepare horses to go to the farm.

Seeing that Mao Wenlong was so calm, the six of them immediately looked at each other, and they all saw a look of surprise in each other's eyes. Obviously, Mao Wenlong is so confident, most of this thing can't be faked.

Only Hong Chengchou still insisted that Mao Wenlong was lying, after all, he had been to Ye County two or three times before and after, and he had never seen any sweet potatoes.

Most of Yexian County is still a barren Gobi Desert, and when the wind blows, dust flies all over the sky. If the so-called grain yield of 5,000 catties per mu can still be grown in such a bad environment, this has completely subverted Hong Chengchou's cognitive scope.

Soon, everyone galloped to the farm, handed over the horses to the guards outside the farm, and Mao Wenlong took the lead and walked in.

Hong Chengchou, Li Jie and others followed, all with curiosity and expectation in their eyes. Mao Wenlong did not disappoint them, and as soon as he walked into the farm, it was completely a paradise.

Everywhere you look, there are green sweet potato vines, and a few people walking in them feel like they are in a sea of green.

"This ...... This is the sweet potato? Hong Chengchou's face was full of disbelief, and he couldn't imagine when such a paradise appeared in a barren Xiaoye County.

Mao Wenlong is very proud, the farm has been developed for a year, and now it is almost perfect. Although the place is still very dry, the solution is not impossible, at most it is to spend more effort and use more labor.

"That's right, it's sweet potatoes!" After speaking, Mao Wenlong directly called the people who were weeding not far ahead, and asked him to dig out the sweet potato that Hong Chengchou pointed to just now.

The old man's hands and feet are very sharp, and his experience is even more sophisticated, and after three or two hoes, a few large sweet potatoes immediately appeared in front of everyone's eyes.

This sweet potato has obviously finished ripening, and each of the six sweet potatoes dug up weighs three or four catties.

Mao Wenlong directly picked one up and threw it to Hong Chengchou, who caught it carefully, and then began to look at it carefully, and found that it was indeed the same as the sweet potato they had just eaten.

At this time, Hong Chengchou has all his doubts, and in the face of the facts in front of him, even if he feels illogical, he has to admit that Mao Wenlong did not lie to them.

Li Jie and the others were already so surprised that they opened their mouths wide and forgot to close them. Looking at the endless sweet potato fields in front of them, they really couldn't estimate how much harvest they would have.

Mao Wenlong looked at their shocked looks, a trace of disdain flashed in his eyes, and he secretly thought in his heart: "Sample, now I just want you to see what is planted in the farm." There are nearly 10,000 acres of newly developed fields outside Laozi! ”

After the shock, Hong Chengchou began to wonder, he hesitated for a moment, and then asked: "Although the terrain here is better than other places, it should also be an arid place, how did you grow sweet potatoes that grow so well?" ”

Hong Chengchou had been paying attention just now, the field in front of him seemed to be very wet, there was no drought at all, and he couldn't see any water source nearby, so he really didn't understand how Mao Wenlong irrigated?

Speaking of this, Mao Wenlong was even more proud, thinking that in order to solve the problem of irrigation and not wasting water resources, he wanted to break his head.

Later, he still patted his head and remembered the technology of drip irrigation in later generations, although he thought of the technology of drip irrigation, but how to drip irrigation also took Mao Wenlong a lot of thought.

In the end, with the efforts of all the craftsmen in Ye County, this irrigation system was finally come up.

Every five acres of land is arranged a cistern, and there is a well next to the cistern, and there is a huge wooden barrel next to the well.

The large barrel is supported by a wooden frame at the bottom more than three meters high, and next to the barrel is an animal-powered water truck. An old cow is tied to a rumbling cow and is spinning in circles, and then uses a few gears to turn the waterwheel.

In this way, the water in the well is constantly brought up to the large wooden barrel above for storage. Underneath the barrel is a large bamboo link, which has been condensed inside.

A dozen smaller bamboos are attached to the large macaroni bamboo, which are also congratulated and run along the sweet potato field.

Mao Wenlong squatted down and brushed the branches and leaves of the sweet potato with his hands, and a bamboo could be seen extending from the exposed roots. Where the bamboo collided with the soil, the bamboo was made into a hole the size of a pinpoint, and water was dripping out of it.

Mao Wenlong said with a smile: "This is drip irrigation, the water does not need to flow out, just a small drop, so that the maximum saving of water resources, and will not make crops short of water."

Hong Chengchou, Li Jie and others thoroughly understood this set, and after Mao Wenlong's drip irrigation, they all admired it so much.

Hong Chengchou sighed even more: "If the people had understood such a set of techniques, they would still be worried that there would be no grain harvest, and the court would not need to be so anxious." ”

Mao Wenlong pursed his lips directly, he was not interested in listening to any emotion, and now he has confirmed that he is not lying. It's time to go back to the previous question, that's the point.

"Okay, now you don't think I'm lying!" Mao Wenlong stood up and swept his gaze over everyone.

Including Hong Chengchou, they shook their heads again and again, indicating that Mao Wenlong did not deceive people.

After a little smugness, Mao Wenlong said: "Then let's go back to the previous question, I can give you 10,000 sweet potatoes, can you bring me back 5,000 young people." ”

Li Jie was the first to stand up, and said with a smile: "Chief soldier, you also underestimate us, just sweet potatoes like you, let alone bring back 5,000, even 10,000 is no problem at all." ”

Hearing Li Jie say this, Mao Wenlong made a decision on the spot and sent 500 of Li Jie's subordinates, who brought 10,000 sweet potatoes in exchange for 10,000 young people.

On the same day, Mao Wenlong asked people to load sweet potatoes in an ox cart, and Li Jie called Fan Kaiming and Ju Yingzhuo to go with him before leaving. In this way, early the next morning, Li Jie took 500 of Mao Wenlong's subordinates and 10,000 sweet potatoes to Shaanxi to recruit troops.
