When the huge watermill was erected, the people cheered.

After the installation of the waterwheel designed by Du Yuhan, it can be operated by manpower, and if there is water in the river, it can also run automatically with the power of water.

However, when there is no current, it will be necessary to use manpower.

In fact, Du Yuhan can also be designed to be pulled by livestock, but now livestock are used to cultivate land, and the number is small, and it is more expensive than people. She didn't design a watermill powered by cows and horses.

After the installation of the waterwheel, Du Yuhan asked a few young men to start stepping on the pedals on the waterwheel with their feet according to her instructions, and the huge wheel-like waterwheel began to rotate.

The bucket at the top of the spoke is filled with water, which gradually moves from low to high, and then slopes again, and the water in the bucket naturally flows into the aqueduct and then into the newly dug canal. Little by little, the water flowed down the canal into the nearest open field.

The watermill was undoubtedly a success. Many children and adults ran with the water, and everyone cheered when they saw the water flowing into the fields.

This time the cheers were very enthusiastic, and everyone saw the results with their own eyes, the waterwheels can water the fields, as long as the river is not dry, they can use the river water to water the ground, no longer have to carry buckets of water. That's a big deal.

In fact, this waterwheel was invented a long time ago, but many people have forgotten about it. And the north uses it less, so few people can think of it. I just can't do it when I think about it.

Many of the villagers are scrambling to get on the water wheel, trying to step on the pedal to control the water wheel.

In the future, everyone will have to take turns to operate this waterwheel. In order to gain time, it is necessary to keep the waterwheel turning around day and night, and strive to water all the fields in Laohewan Village as soon as possible.

For those fields that do not have good canals, everyone must work hard to make sure that all the fields can be watered.

Now that the drought is so dry, the water in the river is much less than last year, and everyone is afraid that the water in the river will dry up, and now they can produce more grain by watering one more acre of land, and they will be able to eat one more bite of food.

Gu Qishen was very happy to see this achievement, and said, "Today is really worth the trip." Got such a good way to irrigate the farmland. In fact, I also thought of this solution, but there is no specific example of success here in City C, and now seeing your success here also gives me a lot of confidence. ”

Du Yuhan said: "I think of the waterwheel because Laohewan Village is close to the river, and if there is no water source nearby, it will be useless. ”

Gu Qishen said: "Yes, there is no water source in many places, and water conservancy construction has a long way to go." ”

The weather has begun to gradually warm, and Du Yuhan told Liang Shouzheng that the fields should be ploughed to prevent pests and diseases and increase yields.

In fact, it is better to plough the field several times, and some insect eggs can be frozen to death in winter, but where there are such conditions now, it is obviously not possible to rely on manpower alone.

Liang Shouzheng is now convinced of Du Yuhan's words. He immediately asked a village cadre to organize some people to start plowing the land, starting with the fields near the river, and by the way, trimming the land for irrigation.

The irrigation canals were dug shallower this year and then deepened slowly. After all, the amount of work is too large, and these hundreds of people in the village alone will not be able to dig it all this year, so they can only dig shallower first, and dig the fields near the river first.

If they can get more food, they can get some, as long as they can ensure that no one in their village starves to death, it is a victory.

Du Yuhan looked at the villagers' manual ploughing efficiency was too low, and sighed: "It would be nice if you could use machinery to plough the ground, which would not only be efficient, but also deep." ”

Gu Qishen listened to Du Yuhan's words next to him and said, "Are you using a tractor to turn the ground with machinery?"

Our country has already begun to explore agricultural mechanization. It's just that the technical ability is limited, and the failure rate of the produced tractors is somewhat high. Not many people can repair this tractor, so it is a hassle to find someone to repair it once it breaks down. ”

Du Yuhan said: "Isn't there a tractor factory in our C city? If every village had a tractor and special agricultural equipment, the villagers would be much more efficient in farming. Don't be afraid if the tractor breaks, and you can't repair it in time.

During the farmer's farming season, the tractor factory can organize a maintenance team to go to the countryside to repair the faulty tractors in the villages. When the farming season is over, the tractor is not used very much. It won't be busy again until harvest season.

In this way, it is also possible to collect the causes of drag-and-pull failures and improve the technology. ”

Gu Qishen's eyes lit up when he heard Du Yuhan's words, and said with a smile: "Your method is good. As long as the farmland is cultivated in time, it will be a big victory if the season is not missed.

It's just that the scale of the tractor factory in our city is not large, and the tractor factory in so many villages can't supply it at all. ”

Du Yuhan said with a smile: "This tractor must have been purchased by the village organization and is collective property, but there must be some villages that are unwilling to buy it or can't afford it, so it's not something we can force on." When the villages that didn't buy tractors in the future saw the benefits of using machinery and wanted to buy them again, it would be later.

If the supply is really not enough, it will be supplied according to the target set by each township. This way you can always get a share. ”

Gu Qishen nodded and said, "What you said makes sense. It's just that the agricultural machinery that matches the tractor is not very useful as far as I know, and it needs to be improved. ”

Du Yuhan said: "I have some ideas in my head, I will draw you a few drawings when I go back in a while, and you can show them to the masters of the tractor factory to see if they can be used." ”

Gu Qishen was very interested in listening to Du Yuhan's words, maybe Du Yuhan could surprise him, didn't he already give him a surprise.

Gu Qishen said: "Then I'll wait to see your drawings." If it is feasible, I will make the decision to give Laohewan Village a special approval for a tractor. All the machines produced can be tested in Laohewan Village first. ”

Du Yuhan smiled when he heard this: "Then we can decide." At that time, Laohewan Village will be the first experimental site. ”

Liang Shouzheng listened to it next to him, and he knew that Du Yuhan must be sure to draw usable drawings, otherwise she wouldn't have said that.

In this way, their village can get a special approval for a tractor, as well as supporting agricultural machinery. Du Yuhan is really the lucky star of their village.

When he went back, he had to talk to a few village cadres that he would have to take more care of Du Yuhan in the future and try to keep people in Laohewan Village.

Du Yuhan took several degrees in his previous life, although he did not study mechanics professionally, but he also had some foundation.

During this time, she asked her grandson Du Zhuoyuan to find her a lot of books and materials on machinery, as well as lecture videos, and she was learning professional knowledge related to machinery.
