China has been a major agricultural country since ancient times. In a country where "food is the sky", the development of agriculture is crucial.

In the 5,000-year-old Chinese civilization, the continuous evolution of agricultural tools has played a non-negligible role in the development of ancient agricultural culture.

"If you want to do a good job, you must first sharpen your tools", with good tools, you can do things with half the effort.

Farming tools not only shorten the working time of farmers, but also improve labor efficiency.

Farm tools are an important part of China's agricultural culture.

China's ancient agricultural tools have always been in a leading position far beyond the rest of the world at the same time.

The water flow of the Daoyuan River is gentle, while the drum cars, especially the high drum cars, need to be pounded by the turbulent current. Wei Renshi knew a kind of waterwheel that needed a smooth flow of water.

This kind of waterwheel is combined with the bamboo that can be seen everywhere in Shangchang Valley, and Wei Renshi feels that the method he thinks of can basically achieve a low-profile version.

"Oh?" Zheng Lizheng was a little surprised, but also curious, so he asked, "What is Xiao Langjun's method?" ”

"Dig a pond on the back slope to store water, connect the bamboo as a pipe, and use a dump to introduce the water into the bamboo pipe, so that the water is stored on the back slope." Wei Renshi said simply: "The back slope is higher than all the fields in Changgu, and bamboo pipes are drawn from the back slope reservoir to the fields. The bamboo pipe goes straight into the field, drilled with small holes, and the water in the pipe seeps out from the small holes and drip directly into the soil near the root system. In this way, there is no need to carry water manually, and the water is naturally poured into the field, day and night. If you don't need to water, just disconnect the dump from the water receiving plate. ”

"Huh?" Li Zheng opened his mouth, as if he was a little startled by Wei Renshi's thoughts, or maybe he didn't understand.

Wei Renshi knew that hearing was better than seeing, so he didn't say much at the moment, so he walked out dozens of steps with an axe, cut off a few bamboo poles with an axe, and went to the branches. Xi'er reacted at this time, and hurriedly ran over and helped drag it over.

Looking left and right, there is no gun that can pound through the bamboo pole, so it has to be cut from the bamboo joint, and then the two ends are sharpened, stuffed into another section, and connected into a tube.

"Xiao Langjun, what are you doing?" Rizheng asked.

Wei Renshi smiled and didn't answer, but continued to sharpen the bamboo poles, put three vertically, and cut a few small holes on them.

Then I put a longer one horizontally. Three holes were made in the long one, and the three vertical ones were inserted into them.

And he attached two other knots that bent upwards at the end of the long one, so that water could be poured into it.

He drew three shallow trenches on the ground and said to Li Zheng: "This is next to the crops planted after the field is ploughed." ”

Then I put the simple bamboo pipe made of bamboo knots into it. Three vertical ones were right in the middle of the three shallow moats, and one horizontal one was long and parallel to the side of the road.

Then, a few more stones were placed under the long one, so that they were slightly above the three vertical ones.

It's like a "卅" character that erases the lower half of the shape.

"This one is placed on the edge of the ground, all the way to the cistern." Wei Renshi said as he asked Xi'er to scoop a scoop of water into the bucket, then poured it into the long pipe, and said, "This is like the water left from the cistern along the bamboo pipe." ”

Soon, the water flowed into the three short bamboo pipes and leaked out through the small holes cut out of them, wetting the ground next to them.

"Got it!" Li Zheng slapped his hands vigorously and said excitedly: "I understand, I understand!" Xiao Langjun's ingenious thoughts! ”

It's the most rudimentary drip irrigation system – barely counted.

"If this set of things can be made, it will be watered in the future, and there will be no need for people to carry water back from the river." Wei Ren really saw that Li Zheng understood, so he smiled.

"Good stuff, good stuff!" Li Zheng rubbed his hands, looked at the simple model made by Wei Renshi on the ground with a light in his eyes, and suddenly frowned again, and said, "It's very easy to dig a pool on the back slope." There is no shortage of bamboo poles here, and the village is not big, so it is not very difficult to make. But how can water lead up the back slope? Can't do it, and it can't roll over. ”

The topography of Fuchang is actually a plain, so even if the terrain of Changgu is slightly higher, it is not much higher. The back slope is said to be the back slope, which is the highest point in the village, but in fact it is just a mound.

It's not hard to lead the water up.

"The current rollover is naturally not good, but I can improve it, and the improved one will work." Wei Renshi smiled: "Just find a few wheelsmiths and carpenters, and give me instructions." ”

"This ......" Li Zheng thought for a while, and said, "If you really do this, the movement is not small." Can Wei Xiaolangjun really lead the water to the back slope? ”

"Really." Wei Renshi nodded.

"This matter concerns the whole village, I think carefully and speak carefully!" Mrs. Tai listened to Wei Renshi's neat and crisp answer, so she reminded her loudly.

Wei Renshi turned around and replied, "Don't worry, Auntie, the child knows it." ”

Li Zheng couldn't pay attention for a while.

Wei Renshi's idea is excellent, and if the mold he made casually can really be made in the village, he will really not worry about carrying water to water the fields in the future.

But this is a big project, and once it is done, I am afraid that everyone will have to work hard. Labor is nothing, I am afraid that the water will not be able to be brought up at that time, and the labor will also be produced, and there will be no results, and the agricultural time will be delayed for several days. That's a sin.

"Uncle Zheng doesn't have to worry about delaying the farming time, as long as there are enough people, digging ponds and erecting bamboo pipes can be fast. You can find a few wheelsmiths and carpenters first, and make my improved overturned car first. Wei Renshi naturally understood the concerns in his heart, so he said: "When the time comes, if my improved overturned car can lead the water up, then Uncle Zheng can also go to the village to talk." If not, I will play tricks on my own, and I will pay the wages of the wheelsmith and carpenter, and I will not be able to delay the farming time in the village. ”

Xi'er on the side was shocked when he heard this, and hurriedly looked at Mrs. Tai. Mrs. Tai frowned slightly, but when she saw Wei Renshi with a faint smile on her face, she looked completely confident, hesitated, held back first, and didn't say anything.

Li Zheng thought for a moment, then waved his hand very magnificently, and said: "After all, it is for the village, if it really doesn't work, this salary will come out!" ”

After that, his eyes secretly glanced at Mrs. Wei, and Wei Renshi looked at him squarely. I snickered in my heart again.

"Thank you." Mrs. Wei bowed slightly and thanked her.

Li Zheng shook his head, and said to Wei Renshi: "There is a rollover car on the side of the Daoyuan River, if Xiao Langjun wants to transform it, he may be able to use it." Tomorrow I will go to the wheelsmith and the carpenter. If this thing can really be done, it will be of great benefit to farming, so I will take Xiao Langjun to the county government to show his merits! Maybe you'll get a reward from the county! ”

It's a good performance, and it would be better if you could reward some resources. The family is living so hard, and it is the top priority to try to earn money and food as soon as possible!

"Thank you, Uncle Zheng. If you can get into the eyes of the county, it is also the credit of Uncle Zheng, the kid just put forward an idea, if there is no support from Uncle Zheng, where can you make it. ”

Wei Renshi complimented Li Zheng a little lightly, and he laughed heartily: "This is the method that Xiao Langjun came up with ingenuity. A certain will not compete with Xiao Langjun for credit. ”
