Tiny streams of water soon flowed into the bamboo pipes, and then spewed out of the small holes, and small jets of water sprayed right under the roots of kudzu.

Guo Dalu stared at those small water columns, as he expected, from the head of the bamboo pipe to the end of the bamboo pipe, with the difference in water pressure, the water column is large and small, urgent and slow, however, this difference does not hinder the big thing, the key is labor-saving, originally Guo Dalu had to water a row of kudzu, carrying a heavy bucket, holding a small spoon, I don't know how many times to bend over, and now, it is just a bucket of water poured down.

Brother Hao jumped high, and his voice was changing his voice: "It's done! Brother Guo, you, you are so smart! How did you come up with this solution?"

Guo Dalu laughed: "Just think about it and come up with it." Actually, this is the problem of people's thinking, many things, in fact, are not very magical, but some people think of it, some people don't think of it, there is a layer of window paper in the middle, and it can be pierced with a single poke.

The Chinese peasants are very industrious and hard, but it has to be said that in terms of farming technology, the pace of development is not fast, Guo Dalu used to read some miscellaneous books, and found that the Chinese peasants more than 1,000 years ago were exactly the same as the way the peasants after the liberation farmed, whether it was farm tools or planting methods, there was no great progress.

This is a lack of innovation.

However, it is no wonder that the peasants, in ancient times, all the technology was in the hands of the government, and the peasants, just talking livestock, as long as they can work coolies, they don't need to be smart, so the government has all kinds of technical books, such as "Qi Min Yaoshu" such a tall book, but in the field, the old farmers still use the same old style of farming, and their ancestors have not changed much.

Even on the contrary, if someone dares to toss new tricks, they will definitely be scolded by the older generation as a loser.

However, Guo Dalu can shoehorn the way of thinking and ideas from the 21st century into the current era without any psychological burden.

Brother Hao'er's cheers attracted the attention of several farmers next to him, although they were in a hurry to water, but they still cast their eyes over, and when they saw Brother Hao went to pick up a few buckets of water, and poured them under the roots of kudzu grass through bamboo pipes, there were a few people with flexible brains, and they immediately understood what they were doing.

A family couldn't help but run over: "Brother Hao, brother Guo, what are you doing here--alas, this is made of bamboo pipes, oops, this method is good, I didn't think of it before!"

Sure enough, the drip irrigation method is not a particularly difficult technique, and the man of the farmer's house only looked at it, touched the bamboo pipe and the hole on it, and immediately understood the method and general principle of the method used.

Therefore, many technologies are just a layer of window paper, which can be broken when stabbed, as long as you are not a fool, you can understand it.

There was a commotion in Guo Dalu's farmland, more villagers crowded over, and some people specially picked up a few buckets of water, tried it with their own hands, and soon watered all the kudzu grass in an acre of land. If it weren't for the fear of watering more and rotting the roots of the kudzu grass, other villagers would have wanted to try a few more times.

Old Village Chief Zhu hurried over: "You are all full, why don't you hurry up and water the kudzu grass, what are you talking about here?!"

The villagers hurriedly made way for the old village chief Zhu and said, "Village chief, come and see - look at this thing, this thing is really godly, and it is very convenient to use it to water the kudzu grass." ”

"It's just, alas, why am I so stupid in this brain? I used to see that the whole family was tired and tired of watering, why didn't I think of this idea. A few bamboo pipes can be built together, and this hillside is full of bamboo forests, even if all the kudzu grass is covered with this thing. ”

Old Village Chief Zhu squeezed to the field, carefully inspected the drip irrigation system, and looked at Guo Dalu with blazing eyes: "Who came up with this thing?"

Brother Hao was about to speak, Guo Dalu had already rushed to say: "I came up with Brother Hao together, yesterday the two of us went up the mountain together to cut bamboo and build a shelf." ”

Brother Hao was stunned, and just wanted to deny that this was his idea, he just started yesterday, but Guo Dalu gently touched his bare feet next to him, and Brother Hao immediately closed his mouth - Brother Guo can do whatever he wants.

Old Village Chief Zhu took a deep look at Brother Hao and Guo Dalu - the old tree becomes a spirit and the old man becomes a ghost, and the old village chief Zhu doesn't believe a word of Guo Dalu's words!

Brother Hao grew up under his watch, this kid is bold and sensitive, but it is absolutely impossible to come up with these things out of thin air to water Ge Mo - if Brother Hao came up with the idea, then he would have come up with it a few years earlier. Why didn't you come up with this wonderful way sooner or later, just a few days after Guo Dalu went home?

The elder of Zhu Lao Village narrowed his eyes and did not continue to ask, the reason is very simple, because this thing is really good, if the villagers can use this thing to water the kudzu grass, it is a great thing, since it is a good thing, he can't expose Guo Dalu's lies.

Old Village Chief Zhu squatted in the field and touched the rubber tube used to connect between the bamboo pipes: "What is this?"

Guo Dalu lied without blushing: "It was the intestines of an unknown beast that I beat in the mountains." ”

"Do you still have this kind of intestines? You need a lot of intestines to connect all the kudzu grass to bamboo pipes. "Old Village Chief Zhu knows that this is definitely not the intestines of a beast, but he can't tell what this thing is, but since Guo Dalu said that this is a intestine, it is a intestine.

Guo Dalu shook his head: "No, there are not many intestines, and they are all used." ”

A villager next to him said: "We can try to use other intestines, pig intestines, beef intestines - simply do not use intestines, use wood to make an interface, or you can connect bamboo pipes." "It's true that the rubber tube only serves as a connection, and many other things can replace it, and although the seal is not as good as the rubber tube, the slight leakage is not a big problem.

The villager who talked just now will point to the carpenter's craft, surnamed Zhou, he pondered for a while, and then proposed an alternative method, he gestured: "I can take a whole piece of wood and cut it out, and use a red-hot iron rod to make a hole in the middle, so as to ensure that there is no seam after the bamboo pipe is set." ”

Old Village Chief Zhu slapped his thigh: "That's it! Everyone will finish watering today's water first, and then they will all go up the mountain and cut bamboo!"

The villagers cheered and returned to their fields with buckets, and soon the news spread among the villagers who did not yet know the situation, and the fields burst into laughter.

You must know that watering kudzu grass is the heaviest farm work in the whole village, if you water the kudzu grass will be punished from above, a few bamboo pipes can free all the villagers from heavy labor, and naturally every household smiles.

As soon as the watering was over, the villagers went up the mountain to cut the bamboo, Brother Hao ran before and instructed the villagers not to cut too thick bamboo, only the size of a little thumb is enough, if someone asked why, he said seriously: "Brother Guo said." The villagers who asked immediately stopped talking, and they were not stupid, and they also guessed that watering kudzu grass with bamboo pipes was Guo Dalu's idea. Naturally, what Guo Dalu said was what he said.

Guo Dalu had nothing to do, the old village chief Zhu pulled him, and asked him without a word, and asked him in and out of words, whether he had seen this bamboo pipe watering somewhere before - in the end, or the old village chief Zhu didn't believe that Guo Dalu came up with it himself, Guo Dalu was only seventeen or eighteen years old, no matter how smart he was, it was impossible for him to come up with it out of thin air.

Guo Dalu didn't hide it, and said calmly: "This bamboo pipe watering method, called drip irrigation, is indeed not something I came up with, I heard from overseas strangers that in a desert somewhere in the Western Regions, local farmers water crops in this way." ”

The old village chief Zhu blinked his eyes - what the Guo family boy said, nine times out of ten it is true, the method of watering the villagers in the desert - well, this is really possible, because except for the place in the desert where water is more valuable than gold, no one else will think of such a watering method, even in the ravines and ravines where water is scarce, there are always mountain ponds and deep wells that can carry water to water the ground.

Drip irrigation, this drip word is used well, but it's not a drop of watering.

Guo Dalu was dealing with the interrogation of the old village chief Zhu, while watching Zhou carpenter with a few villagers to process wooden connection kits, Zhou carpenter's name Zhou Laiyu, ancestral carpentry skills, the villagers made furniture, made a bucket for children and grandchildren to find him.

Zhou's carpenter's craftsmanship is not blown, a piece of wood came to his hand, a chisel and a knife were scraped for a while, and then a red-hot iron rod was stabbed at both ends, which immediately became a casing, and the two bamboo pipes were docked and tightly fitted.

Carpenter Zhou said: "I have already asked someone to go fishing, and when I take the fish maw and boil some fish glue and apply it to the interface, not only does it not leak, but it is also very fast." ”

Guo Dalu nodded secretly, this is an expert, he has to come up with ideas and really work, and he has to rely on them, the real working people.

Guo Dalu pulled Carpenter Zhou, and explained the details of setting up multiple irrigation outlets according to the length of the bamboo pipe in order to water the kudzu grass evenly, and he couldn't explain what the pressure was, but the Zhou carpenter understood when he heard it, and he patted his thigh: "Guo family boy, I have a method that you don't like - set up a big water tank at the head of each mu of kudzu grass field, each sink is connected by an open channel, and then make a water wheel by the stream, and the entire organ gate on the water tank." After the waterwheel pumps the water into the trough, the amount of water reaches the pre-drawn position, touches the mechanism, and as soon as the gate opens, the water in the trough automatically flows down the bamboo pipe to water the kudzu grass. As soon as the sink is empty, the sluice gates close automatically, and then wait for the next waterwheel to draw water. ”

Guo Dalu was dumbfounded - damn it, this is a set of automatic water supply system, the principle is exactly the same as the system of the 21st century, except that the automatic water pump is replaced by a rickshaw water truck.

I used to laugh at the ancient working people for only knowing how to work hard, what a pig brain!
