There was a wheat field in the village, which was a large open space, and after noon, Li Zheng organized the whole village and called out there.

Zheng Li is very appealing in Changgu, and many people from the village have come, not only young and strong, but also older and capable of working.

Li Zheng waited for everyone to arrive, then raised his hand and pressed down, so that everyone stopped talking, and said to everyone: "The Wei family in the village, everyone knows that they have always been talented. No, this time Wei Xiaolangjun is also a piece of material, first made a new plow, a certain few days have been used, than the plough we used before, more than a star and a half, I think the big guy has already heard of it. ”

Everyone buzzed in a few times, and then listened to Li Zheng continue: "No, Wei Xiaolangjun gave another way and came up with such a watering mechanism called the drip irrigation system. The big guy doesn't have to know what a drip irrigation system is, he just needs to know that after this mechanism is completed, we won't need to carry water to water the fields in Changgu from time to time in the future. In the fields of our village, the water can flow to the fields by itself in the future, as long as you want, it will not be a problem to water day and night! ”

This sentence was as if cold water had been poured into hot oil, and the surrounding villagers exploded in an uproar.

"Don't you have to carry water?"

"Water flows into the fields and waters?"

"Day and night?"

The people of the village were all taken aback.

Zheng Lizheng said again: "Summoning the big guys here today, that is, this matter." This watering mechanism is very large, and it requires the help of all the people in our village. A certain person will say it first, but whoever contributes to it, the watering mechanism will be led to his field. If you don't want to do it, if you steal and play tricks, when the time comes, you will vacate his land and let his family go to fetch water and water the land. However, we don't have such a bad person in Changgu. Next, let's break it down. ”

Zheng Li is arranging manpower, some people continue to cut bamboo, some people connect bamboo tubes together, some people dig water reservoirs on the back slope, and some people connect bamboo tubes from the back slope to the fields below.

Wei Renshi is also busy, he has to run everywhere, every place has to be explained clearly, explain clearly, watch them make a few finished products, and then change to the next place after no problem.

The people of a village are busy with this matter, and the so-called large number of people is powerful, and it only took one day to complete the reservoir.

The lid of the clay embryo was burned again, and when a set of systems was completely completed, the lid of the clay embryo was closed to prevent evaporation too quickly and to prevent people from falling in.

According to Wei Renshi's suggestion, a net was also woven with bamboo strips and placed in the place where the bamboo pipe would be connected to prevent garbage from flowing into the bamboo pipe and clogging the bamboo pipe.

On another day, the bamboo canal that connected the keel plate to the cistern was also built, and the widest ones were used.

The water is brought ashore by the overturned cart and pushed up by the keel plates – the long keel plates are spectacular, the length of the keel plates is longer, the slope becomes smaller, and the water is easier to be pushed up - into the bamboo canal, and at a slight angle, it flows down the canal into the reservoir on the back slope.

"It's done! It's done! Seeing that the water in the reservoir gradually increased, Li Zheng slapped his legs and laughed, and said to an old man beside him: "Sixth uncle, when this set of organs is all ready, you have to call the eldest lady to come back and live in her mother's house for a few days." ”

These words were strange, and Wei Renshi turned his head to look at it.

Zheng Lizheng saw Wei Renshi looking at him, so he smiled and said: "The son-in-law of the sixth uncle's aunt is now working as an errand in the county office. ”

The sixth uncle laughed and said, "Li Zheng wants to borrow the mouth of the old man's aunt?" He's just a servant, Zheng Lizheng is a person who has a relationship with the county, and he still needs him? ”

"It's always proof." Li Zheng smiled: "You can't do it!" ”

"Done! Why not! The old man smiled and squeezed into one place with a wrinkled face, and said, "We have a mechanism in our village that can water by yourself, and there is light on your face when you say it!" Huh-Wei Langjun is really a capable person, how can he come up with such a powerful mechanism! ”

Wei Renshi smiled: "You praise it for a long time." ”

The bamboo pipes in Changgu are in full swing, and after the bamboo pipes come down from the back slope, they only need to pile up four bricks and stones, and then reduce them one by one, and they can be connected to all the fields in Changgu.

It's the terrain that's helping!

There are a lot of fields, so it is the most laborious to introduce bamboo pipes into each field, not to mention the small holes that need to be cut into the bamboo pipes after entering the field.

The cistern was nearly full in two days, and Rizheng had to bring a few people over to separate the keel plate from the waterwheel.

"In the future, if you don't need to water for a while, you can disconnect it like this, and then connect it in advance if you need it." Wei Renshi said with Li Zheng, and as soon as he finished speaking, a flash of inspiration suddenly flashed in his mind, and he said: "Uncle Zheng, you said that if we get a few more of these waterwheels and long keel plates, dig a few more reservoirs, and connect bamboo pipes to every household, wouldn't we even need to mention the water at home?" ”

"Huh?" Zheng Lizheng was stunned.

Wei Renshi laughed, and it was a joke. The amount of work is much larger, and the amount of water used is much larger, and it is not something that can be completed by a village, and the waterwheel cannot push such a large amount of water.

Eight days passed, and with the concerted efforts of the whole village, the bamboo pipes were finally connected to every field in Changgu. Thanks to the fact that Changgu is a plain as a whole, it is much more convenient.

The keel plate and the waterwheel were joined together again, and the water in the cistern on the back slope gradually increased.

"Connect it!" Wei Renshi said.

A few young men next to him immediately connected the bamboo pipe to the outlet of the cistern.

The water flowed down the bamboo pipes, and the water in the cistern first decreased rapidly, but after a while, it slowed down, and with the water flowing from the bamboo canal, it was almost flat.

Leaving a few people there, Wei Renshi ran into the field.

As soon as he approached the ground, he heard someone shouting, "Out of the water!" Out of the water! ”

When I ran over, I saw that water was seeping out of the small holes in the thin bamboo pipes in the field, and the ground was already wet.

Because the thin bamboo pipes in the field are not far apart, they are laid in parallel at a distance of nearly one step, and the small holes on the bamboo pipes are also nearly one step apart from each small hole, so the ground is very wet.

Wei Renshi ran all the way down the field, and the shouts of "out of the water" full of surprise were heard the most.

Looking all the way, the closer to the back slope of the ground, the faster it gets wet, and the slower it will be, but there is always water flowing, which is slightly slower than the front, but it does not delay watering.

In addition, when the bamboo pipe is connected to the ground, there is a cut in the middle, and the bamboo piece can be inserted to block the flow of water, which is equivalent to a valve.

Not bad! Wei Renshi stood on the ground, very satisfied with his ultra-low-profile drip irrigation system.
