Although Cheng Yuan's hometown is good, after all, the place is small, the pattern is small, and after playing for nearly half a month, it is basically time to watch and play.

Of course, in this period, Cheng Yuan is not just looking at the scenery everywhere, he also has an important activity, that is, visiting relatives and visiting people.

This is also an unwritten old custom in Linjia Village, generally speaking, if there are children in the village, most of them will be taken around by their parents, chattering and pulling relationships at the same time, mainly to promote their children's skills, so that others can recognize.

This unwritten custom is at best a show-off, but in good terms, it can also be seen as a primitive mutual aid mechanism for the villagers.

This is because after the people in the village go around, they will let the people in the village recognize him, and realize how much he is capable of, so that if the people in the village have any problems in the future, they can think of this capable person and then ask for help.

Generally speaking, if the villagers come to you, then as long as it is not something you really can't do, you always have to help the villagers, otherwise you will be poked in the back, and the family will not be able to raise their heads.

It is with this mechanism that the talents of Linjia Village are still so united, for example, when Cheng Yuan went to school, it was because he asked the village director that he received a financial aid for Cheng Yuan, so that Cheng Yuan could go to school in the county.

It can be said that if it weren't for the help of the old village director to find a relationship, even if Cheng Yuan's academic performance in the village was good, it would be impossible for him to go to the county's key middle school, and if he couldn't go to the county's key middle school, he would not be able to be admitted to Upper East University, and he would not be able to stay in Upper East, and naturally, he would not be able to encounter the alien inheritance.

But it's a pity that the old village director's family, who had been far away from the funding process, had already moved out. has become a city hukou, and people's family conditions are also good, there is nothing to need Cheng Yuan's help for the time being, and if others don't ask for you, but you rush to help, it will cause others unhappiness, and you will be said by the villagers.

Although he couldn't repay the old village director's family, for the villagers in his village, Cheng Yuan decided that he should do more.

The so-called teaching people to fish is not as good as teaching people to fish, but it is only the construction of free schools. Free hospitals and free nursing homes can only make the villagers have no worries, but because the people in Linjia Village have a good face, everyone may be very grateful for this kind of thing with a charity surname, but they may not be very appreciative.

Therefore, in order to make the village truly develop and let the villagers truly gain self-confidence, the key is to give the villagers a way to make money, so that they can make money with their own skills. In that case, Cheng Yuan's family can gain the true respect of the villagers.

Linjia Village is a traditional rural village with many plains and few mountains. Therefore, the main income of the village is obtained through farming, and the education level of the villagers is generally not high, and it is obviously unreliable to build high-tech factories before the new generation of talents rises. Therefore, it is necessary to give them a project that is easy to learn and easy to make a fortune.

After thinking about it, Cheng Yuan felt that most of the people in the village had been farming all their lives. It is very good at making crops and vegetables, and it is better to do it raw than cooked, and it is the most reliable to develop a new type of ecological agriculture project in this village.

In fact, in the past, from counties to towns, they paid great attention to local agricultural development, such as building roads and reservoirs, all to promote local agricultural production.

However, agricultural production itself is actually a complex industry with high input and high risk, and it does not mean that if you build a few more roads and reservoirs, the income of the villagers and the level of local agriculture can be greatly improved immediately.

Compared with large-scale image projects such as building roads, street lamps and reservoirs, it is most reliable to provide farmers with more practical support, such as providing them with small agricultural loans, providing them with high-quality seeds, fertilizers, pesticides, and providing all-round technical support.

Things like providing small loans to farmers, providing high-quality seeds, fertilizers, and pesticides, and providing all-round technical support are quite cumbersome and troublesome, and obviously have no competitive advantage compared with the projects that can make a lot of money and water and political achievements such as building roads and reservoirs. Therefore, the cadres of villages and towns basically do not pay much attention to these things that can actually improve the interests of the peasants, and what they usually pay attention to is nothing more than cremation and family planning, which can be fined, or they are focused on some large projects that can make oil and water, and if they do not care, the development of the villagers can be imagined.

Of course, it is not bad to focus on large projects, at least the infrastructure is good, and it will be much more convenient for Cheng Yuan to engage in those new agricultural projects again.

Cheng Yuan is also from a farming family, and he is in a big city and has a broad vision, so he basically has a rough idea in his heart when he is nearby, especially after walking along the new reservoir.

In Cheng Yuan's view, the land utilization rate of Linjia Village and several nearby villages is actually very low, and most of the villagers' farming methods are extensive farming, not intensive farming.

For example, corn, the largest crop in the local area, is basically planted with the kind of feed corn that is easy to feed, and the cultivation method is simply to turn the ground, sprinkle seeds, apply chemical fertilizers, and then basically ignore it, at most when the pest is high, hit pesticides several times, and then after the harvest season, several companies hire a combine harvester to harvest the corn in one go.

In addition, there are wheat growers, and even rice growers, which are all planted in an extensive manner similar to corn planting, and the yield cannot go up at all.

Of course, there are many reasons for this phenomenon, in addition to the unfamiliarity with new technologies and seeds, there is also an important reason, which is the shortage of local labor.

Basically, Linjia Village is also the same as other rural areas in China, most of the young labor force has gone out to work, and those who stay in the village are basically the elderly and children, and the main force of farming is also the old people and some left-behind women here. Obviously, let the elderly and women go to farm, don't expect them to be productive.

However, this reminded Cheng Yuan and made him realize that his robot technology may be a good way out in the field of agriculture.

In fact, a simplified version of the robot, or a cheap steel version, has already made a breakthrough, and even the production line has been assembled in Sweden, and the prototype has been produced. However, Cheng Yuan has not promoted this technology for a long time, and his scruples are afraid that the early introduction of robot technology will make Huaguo lose its competitiveness prematurely.

Everyone knows that one of the very important factors why China's economy has taken off so quickly is that it relies on cheap and large amounts of labor, and it is cheap labor that has created China's economic miracle. Although now this cheapness is changing, and labor costs are rising, but all over the world. The competitive advantage of the Chinese labor force is still very strong.

And if once vigorously promote robot technology, especially the kind of very versatile humanoid robots, it is obviously a great blessing for Europe and the United States and other countries, but for the technical reserves are not enough, the industrial transformation has not been completed for China, but it is a premature blow.

However, you can't give up eating because of choking, you can't be afraid of these. will not launch robots, so Cheng Yuan decided to launch this multi-functional robot first in some areas where there is a shortage of labor, for example. In agriculture, robots are completely available.

Although the agricultural population in China seems to be large, in fact, with the acceleration of urbanization, the agricultural labor force in China is decreasing year by year. In many places, rural labor has become a scarce commodity, which has directly caused the rapid value-added rate of agricultural production in China.

Don't look at Huaguo's continuous bumper harvest in recent years. However, this is based on the widespread use of chemical fertilizers and pesticides, and the fact that the agricultural foundation is too weak, in terms of agricultural labor efficiency, it is far lower than that of farmers in Europe and the United States.

What Cheng Yuan wants to do now is to make an attempt to see what kind of benefits robotics can have in the agricultural field.

Although the main role of construction robots is to engage in construction, as long as the program is modified and they are allowed to cultivate the land, it is just as powerful.

With Cheng Yuan's design, coupled with Xiaolan's assistance, it was easy to make such a modification, and it didn't take a day for the relevant agricultural skill programs to be entered into the construction robots that were in standby after the construction of the school.

After that, Cheng Yuan had a simple communication with the local town party committee and town government axe leaders, and then began to experiment with the robot surnamed Yakuza on a piece of land that had been carved out.

It turns out that construction robots are not only very powerful in building houses, but also very good at farming!

First of all, the cultivated land, because of the drill gopher, deep ploughing is no longer difficult, and these drill waffle robots in addition to deep ploughing the land, there is also an important role is to drill out some pipes, good installation sprinkler irrigation system.

After the gopher has turned the wasteland into a familiar land for traffic, the next step is to carry out further refinement.

The people who do the refinement are basically humanoid robots and spider robots, and I saw them holding PVC pipes and starting to bury pipes in the preset pipes in the field.

There are two kinds of pipes, one is a sprinkler system combining sprinkler irrigation and drip irrigation, which is mainly used to water plants, and the other is a fertilizer seepage system that seeps water underground, and the main role is to slowly and evenly infiltrate the fertilizer water of organic fertilizer into the soil.

These two kinds of pipes are divided into two layers, above ground and underground, among which the above-ground pipes are water spray systems, which are mainly convenient to disassemble at any time, and the pipes deep underground are dense fertilizer pipes, just like floor heating pipes, the purpose is to let the fertilizer liquid be released directly in the depths of the soil, and use the fertilizer surname of the plant root system to make their roots can be deepened.

Both types of pipelines have many sensors, for example, the water spray pipe can feel the temperature, humidity and light intensity and other information, while the fertilizer pipe can detect the soil pH, rich in trace elements, bacteria and germ concentration and other information, this information is fed back to the computer, so that the computer can make the optimal instructions.

For example, on rainy days, the water sprinkler will not work, and if the pH of the soil is different from the trace elements, you can mix organic fertilizer as needed to allow crops to grow in the best environment.

Of course, these settings are all basic farmland settings, and the situation will be different according to the use of the land, such as whether it is greenhouse farmland, and the relevant settings are different.

The first is the greenhouse farmland, the greenhouse farmland, basically for the out-of-season, that is, to artificially create a greenhouse, so that the crops inside can avoid the changes of the four seasons, and you can produce the crops you want all year round.

In order to allow personnel to enter the greenhouse will not be uncomfortable, so the greenhouse construction is very high, three meters high, and the surface of the greenhouse is a film containing a vacuum air cushion interlayer, which can maximize heat preservation.

In addition, inside the greenhouse, an intelligent ground source heat pump air conditioning system and an intelligent ventilation system will be installed, while a transparent solar panel will be installed outside the greenhouse to make full use of sunlight.

In this way, the ground source heat pump air conditioner inside the greenhouse, as well as the ventilation system, water spray system, fertilizer system, and the electricity used can be provided by solar cells, and the solar cells can also provide enough light to the plants because they are transparent.

The farmland that is not set up in the greenhouse is the open-air farmland, which is relatively simple and not as complex as the greenhouse farmland, but in the middle of the farmland, at certain intervals, a small pond will be dug out, in which fish can be raised, and the water and silt for fish farming can be used as fertilizer for crops.

At the same time, some trap lights and traps will be placed in the open farmland to suppress pests and mice and other pests in a mechanical way, of course, these traps are also intelligent, and they can distinguish whether they are beneficial or pests to be trapped. For example, if it's a bee or a seven-star ladybug, the trap won't work, or if it's a frog, the trap won't work either.

In addition, whether it is a greenhouse farmland or an open-air farmland, there are loudspeakers that can play music when there are people, and when there is no one, they can emit sound waves that plants like according to the type of crops planted, so as to promote the yield and quality of crops.

In short, whether it is greenhouse farmland or non-greenhouse open-air farmland, it is an ecological setting.

Compared with these farmland settings, in fact, the most brilliant thing is that those who make these crops, such as going in to lay seeds, do not need people at all, they can be used by robots, and what humans have to do is just to go in and observe the growth state of the plants up close, so as to judge whether they want to water or fertilize or so on.

In other words, in this new agricultural system, human beings can already get rid of heavy labor, and only need to use their rich experience to judge the quality of crop growth, and make adjustments according to the situation, and all adjustments are automated systems, such as water spraying, fertilization, carbon dioxide, nitrogen, heating, cooling, etc., all are automated! Even removing weeds and pruning branches and leaves can be done by robots, and there is no need for manual labor at all!

This plant farmland is just one of them, other systems such as pigs, sheep and cattle pens around the farmland, underground biogas digesters, etc., are also designed, and after the complete construction, it is an intelligent recycling ecological agriculture system centered on intelligent farmland, around intelligent livestock breeding, fish breeding and green feed and fertilizer processing.

The most important point is that in this new system of intensive cultivation and no heavy physical labor, the crops planted are organic crops, no genetically modified seeds, no pesticides, no herbicides, no mineral fertilizers, and all green organic crops are produced!

As for the cost, the initial investment may be relatively high, but once it is continuously used, and so on this circular ecological agriculture system to fully exert its capacity, then as long as five years, you can return to the capital, and then it is a net income, and a few old people, women and children can take care of a large area, only need to look at the computer monitor at home, move the mouse and keyboard to carry out most of the work, no need for heavy physical labor at all, very suitable for the current lack of young labor force in Linjia Village!
