Although Cheng Yuan's hometown is nice, it is a small place with a small layout. After playing for nearly half a month, he has basically seen and played everything he should. Of course, during these days, Cheng Yuan didn't just go around looking at the scenery. He also had another important activity, which was visiting relatives and visiting friends. This is also an unwritten old custom in Linjia Village. Generally speaking, if a child of a family in the village becomes successful, most of them will be taken around by their parents to visit. While chatting and building relationships, the main purpose is to promote the abilities of their children. , let others realize it. This unwritten custom can be seen as showing off at worst, but at its best, this behavior can also be seen as a primitive mutual aid mechanism for villagers. This is because when a promising person in the village visits people everywhere, the people in the village will recognize him and his approximate abilities. In this way, if the people in the village have any problems in the future, they can think of this capable person. Then go get help. Generally speaking, if a villager comes to ask for you, then as long as it is not something you really can't do, you must always help the villagers. Otherwise, you will be poked in the back and the whole family will not be able to hold their heads up. It is precisely because of this mechanism that the talents in 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 student aid, allowing Cheng Yuan to go to school in the county. It can be said that if the old village director had not helped find connections with money, no matter how good his academic performance in the village was, Cheng Yuan would not have been able to go to a key middle school in the county. And if he could not go to a key middle school in the county If you go to middle school, you won't be able to get admitted to Upper East University, and you won't be able to stay in Upper East. Naturally, you won't be able to encounter the alien legacy. But it¡¯s a pity that the old village director¡¯s family, who once supported Cheng Yuan, has long since moved out. You have an urban household registration and your family is in good condition. There is nothing you need Cheng Yuan¡¯s help for the time being. If others don¡¯t ask for your help but you rush to help, it will cause others¡¯ displeasure. Said by the villagers. Although he could not repay the old village director and his family, Cheng Yuan decided to do more things for the villagers. ¡°It is better to teach people to fish than to teach them how to fish. It is just about building free schools. Free hospitals and free nursing homes can only give the villagers no worries, but because the people in Linjia Village are very face-conscious, everyone may be very grateful for this kind of charity, but they may not necessarily appreciate it very much. . Therefore, if we want the village to truly develop and the villagers to truly gain confidence, the key is to give the villagers a way to make money so that they can make money based on their own abilities. In that case, Cheng Yuan's family can gain real respect from the villagers. Linjia Village is a traditional rural area with many plains and few mountains. Therefore, the main income in the village is obtained from farming, and the villagers are generally not well educated. It is obviously unreliable to build a high-tech factory before a new generation of talents arises. Therefore, we need to give them a project that is simple, easy to learn, and easy to make a fortune. After thinking about it, Cheng Yuan felt that most people in the village had been farming all their lives. He is very good at handling crops and vegetables, but it is better to be a master than a master. It is most reliable to develop a new ecological agricultural project in the village. In fact, in the past, from the county to the town, great emphasis was placed on 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 investment and high risks. It does not mean that if you build more roads and more reservoirs, the income of villagers and the level of local agriculture will be greatly improved immediately. Compared with large-scale image projects such as building roads, building street lights, and building reservoirs, we provide farmers with more practical support, such as providing them with small agricultural loans, providing them with high-quality seeds, fertilizers, pesticides, and providing them with a full range of technologies. Support is the most reliable. Things such as providing small loans to farmers, providing high-quality seeds, fertilizers and pesticides, and providing all-round technical support are quite tedious and troublesome. Compared with projects such as building roads and reservoirs, which can make a lot of money and political achievements, Obviously there is no competitive advantage. Therefore, cadres in villages and towns are basically not very concerned about things that can actually improve the interests of farmers. What they usually focus on is nothing more than cremation and family planning, which can attract fines, or they focus on certain large projects that can make money. If the leaders don¡¯t pay attention, the development of the villagers can only be imagined. Of course, it is not bad to focus on big projects. At least the infrastructure is good. It will be much more convenient for Cheng Yuan to work on those new agricultural projects. Cheng Yuan also came from a farming family, and living in a big city has a broad vision, so after walking around the neighborhood, especially along the new reservoir, he basically had a rough idea in his mind.  According to Cheng Yuan, the land utilization rate in Linjia Village and several nearby villages is still very low. Most of the villagers' farming methods are extensive farming, not intensive farming. For example, the most productive local crop, corn, is basically the kind of feed corn that is easy to grow. The farming method is to simply plow the ground, scatter seeds, apply chemical fertilizers, and then basically ignore it. At most, when the insect pests are high, the crop will be harvested. Several times of pesticide application, and then when the harvest season came, several companies hired a combine harvester to harvest the corn in one fell swoop. In addition, those who grow wheat and even rice are grown in an extensive way similar to corn, and the yield cannot increase at all. Of course, there are many reasons for this phenomenon. In addition to unfamiliarity with new technologies and new seeds, another important reason is the shortage of local labor. Basically, Linjia Village is the same as other Chinese rural areas. Most of the young labor force has gone out to work. Those who stay in the village are basically the elderly and children. The main force in farming is also the elderly here and some left-behind women. Obviously, if you let old people and women farm, don't expect them to be very productive. However, this reminded Cheng Yuan and made him realize that his robotics technology might be a good way out in the agricultural field. In fact, the simplified version of the robot, or cheap steel plate making, has already achieved a breakthrough. Even the production line has been assembled in Sweden and prototypes have been produced. However, Cheng Yuan has been slow to promote this technology. His concern is that premature introduction of robot technology will make China lose its competitiveness prematurely. Everyone knows that one of the important factors why China's economy has taken off so fast is its cheap and large labor force. It is the cheap labor force that has created China's economic miracle. Although this cheapness is changing now, labor costs are increasing around the world. The competitive advantage of the Chinese labor force is still very strong. And if robotics technology is vigorously promoted, especially the all-round humanoid robots, it will obviously be a great boon to countries such as Europe and the United States. However, for China, which has insufficient technical reserves and has not yet completed its industrial transformation, But it was a premature blow. "However, you can't give up eating because of choking, and you can't stop eating because of fear. We will not launch robots, so Cheng Yuan decided to launch such multi-functional robots first in some fields where labor is in short supply, for example. In the agricultural field, robots can be used. Although China seems to have a large agricultural population, in fact, with the acceleration of urbanization, China¡¯s agricultural labor force is decreasing year by year. In many places, rural labor has directly become a scarce commodity, which directly results in the slow value-added rate of China's agricultural production. Don¡¯t look at China¡¯s continuous bumper harvests in recent years. But that is based on the widespread use of chemical fertilizers and pesticides, and the weak agricultural foundation. In terms of agricultural labor efficiency, it is far lower than farmers in European and American countries. What Cheng Yuan wants to do now is to make an experiment to see what kind of benefits robotic technology can have in the agricultural field. Although the main function of construction robots is construction, if you modify the program and let them cultivate land, they can be just as powerful. With Cheng Yuan¡¯s design and Xiaolan¡¯s assistance, it was easy to make such modifications. It didn¡¯t take a day to input the relevant agricultural skills program into the construction robots that were in standby mode after building the school. Afterwards, Cheng Yuan had a brief communication with the local town committee and town government leaders, and then began experimental robot operations on a designated piece of land. Facts have proven that construction robots are not only great at building houses, they are also great at operating agriculture! The first is arable land. Thanks to the gophers, deep plowing is no longer difficult. In addition to deep plowing of the land, these gopher robots also have an important role in drilling some pipes to install sprinkler irrigation systems. After the gophers turn the wasteland into a familiar place for traffic, the next step is to carry out further detailed operations. ??????????????????????????????????????????????????????????????????: Humanoid robots and spider robots are basically doing the detailing operations. I saw them holding strips of PVC pipes and starting to bury pipes in the preset pipes in the field. There are two types of pipes. One is a sprinkler system that combines sprinkler irrigation and drip irrigation. Its main function is to water plants. The other is a fertilizer infiltration system that seeps water underground. Its main function is to slowly transfer organic fertilizer water. Penetrate evenly into the soil. These two types of pipes are divided into two layers: above ground and underground. The above ground pipes are sprinkler systems, which are mainly used to facilitate disassembly at any time, while the pipes deep underground are densely packed circles of fertilizer pipes, just like floor heating. Like pipes, the purpose is to allow the fertilizer liquid to flow directly into the soil.Release deeply, taking advantage of the fattening properties of plant roots, allowing their roots to penetrate deeper. Both types of pipes have many sensors. For example, the sprinkler pipe can sense information such as temperature, humidity, and light intensity, while the fertilizer pipe can detect soil pH, rich in trace elements, bacteria, and pathogen concentration. This information feeds back Go back to the computer and let the computer make optimal instructions. For example, on rainy days, the sprinklers will not work. If the pH and trace elements of the soil are different, organic fertilizers can be deployed as needed to allow crops to grow in the best environment. Of course, these settings are all basic farmland settings. Depending on how the land is used, the situation will be different. For example, whether it is greenhouse farmland or not, the relevant settings will be different. The first is greenhouse farmland. Greenhouse farmland is basically designed to be counter-seasonal, that is, to artificially create a greenhouse so that the crops inside can avoid the changes of the four seasons and produce the crops you want all year round. In order to make it less uncomfortable for people to enter the greenhouse, the greenhouse is built very high, as high as three meters, and the surface of the greenhouse is made of a film containing a vacuum air cushion interlayer, which can maximize heat preservation. In addition, an intelligent ground source heat pump air conditioning system and an intelligent ventilation system will be installed inside the greenhouse, while translucent solar panels will be installed outside the greenhouse to make full use of sunlight. In this way, the electricity used by the ground source heat pump air conditioner, ventilation system, water spray system, and fertilizer infiltration system inside the greenhouse can be provided by solar cells. Since solar cells are transparent, they can also provide power to plants. Sufficient light. Farmland that is not set up in greenhouses is open-air farmland. This kind of farmland is relatively simple and not as complicated as greenhouse farmland. However, in the middle of the farmland, a small pond will be dug at a certain distance, and fish can be raised in it. The water and silt can be used as fertilizer for crops. At the same time, some trap lights and traps will be placed in open farmland to mechanically suppress pests, mice and other harmful organisms. Of course, these traps are also intelligent and can distinguish whether they are beneficial insects or pests. For example, if it is bees, ladybugs, etc., the trap will not work, or if it is a frog, the trap will also not work. In addition, whether it is greenhouse farmland or open-air farmland, there are speakers installed. When there are people around, music can be played. When no one is around, the sound waves that the plants like can be emitted according to the types of crops planted, so as to promote the growth of crops. output and quality. In short, whether it is greenhouse farmland or non-greenhouse open-air farmland, it is an ecological setting. Compared with these farmland settings, the most outstanding thing is that there are no humans at all to operate these crops, such as planting seeds and so on. They can be completely operated by robots. All humans have to do is go in and observe at close range. Check the growth status of the plants to determine whether you need to water or fertilize them. In other words, in this new agricultural system, humans can already be freed from heavy labor. They only need to use their rich experience to judge the quality of crop growth and make adjustments according to the situation. All adjustments, They are all automated systems, such as water spraying, fertilizing, adding carbon dioxide, adding nitrogen, heating, cooling, etc., all are automated! Even weeding and pruning can be done by robots, without the need for manual labor at all! This kind of plant farmland is just one of them. Other systems such as pig, sheep and cattle pens surrounding the farmland, and underground biogas pools are also designed. After the complete construction is completed, there will be a smart farmland as the center and around smart livestock breeding. It is an intelligent recycling ecological agricultural system that integrates fish breeding, green feed and fertilizer processing. The most important point is that in this new system of intensive farming and no need for heavy physical labor, the crops grown are all organic, and no genetically modified seeds, pesticides, herbicides, or Mineral fertilizers are used to produce green and organic crops! As for the cost, the initial investment may be relatively high, but once it is used continuously and this circular ecological agricultural system fully reaches its production capacity, it will only take five years to recover the cost, and then it will be pure profit, and a few old people, women and children can take care of it. A large area, you only need to look at the computer monitor at home and use the mouse and keyboard to perform most operations. No heavy physical labor is required at all. It is very suitable for Linjia Village, which currently lacks young labor force! (To be continued, please search Piaotian Literature, the novel will be better and updated faster!
