[Phát _sốt_ với mô hình Aquaponics độc lạ_ Nuôi cá, trồng rau, nuôi gà ngay sân thượng

Hello everyone, welcome to Diem Hen Kho Hoc. Right now, I'm at a very special eco-experimental area. As you can see, this is a chicken bonnet model. We can see that there are birds, green vegetables, and next to me, this is an aquabonnet model, which will raise fish in the ponds. Combined with growing green vegetables and only with a small area, we can grow a lot of vegetables to make food for the family. And standing next to me is Dr. Pham Van Hoi, who is always concerned about ecological issues. He is also the owner of the eco-models that we have just seen. Hello Dr. Hoi. Hello. Dr. Hoi, can you tell us a little bit about the eco-models here so that the audience can understand better? In this model, in this area, we currently have two different models. You have already seen the external model. We named it Chicken Bonnet, which can raise chickens and combine with growing vegetables. And the model behind me is the aquabonnet model. You already know a lot about it. It is a combination of raising fish and growing vegetables. However, here it is different from the models you see on the Internet. Here we have developed a separate system to help the system grow almost all types of plants. No need to fertilize, no cost, nutrition is not lost. The product is rich, safe and meets the criteria of fresh food. These are the outstanding advantages of ecological systems developed by Dr. Hoi's research and development. In particular, when using the system for the first time, by using regular food, households, especially urban households, can easily contribute to the protection of the environment, reduce the loss of organic life in an effective way. We can see that these models have many advantages, although it is a small area. And to better understand the model and the process that Dr. Pham Van Hoi has studied and designed, now we will watch a short clip about Dr. Hoi that we have prepared. Dr. Pham Van Hoi, who has been teaching and working for 23 years in the field of agricultural ecology and environmental protection, is the character of this week's science appointment. Some of his excellent scientific results can be listed. From 2001 to 2008, he studied the safe, sustainable production methods in Vietnam. From 2009 to 2016, he focused on the study, management, distribution and use of plant-based pesticides in agricultural production in Vietnam, the development of fuel trees on polluted and depleted soil. From 2016 to 2020, he studied solutions to solve the double risk of human health and the environment. From 2020 to now, he has been studying ecological agriculture, the development of a system of biological waste management, the combination of plants, vegetables, and family size. From 2001 to now, Dr. Pham Van Hoi has participated in the coordination and consultation of 33 domestic and international projects, the author and co-author of 12 international journals, the author and co-author of 5 international books, and the author of 12 domestic journals. With excellent contributions to agriculture, especially in the field of agricultural ecology, Dr. Pham Van Hoi has played an important role in the sustainable development of rural agriculture in many regions across the country. Through the clip we just watched, we can see that Dr. Pham Van Hoi has had a lot of work, as well as many years of commitment to the field of environmental ecology. And I don't know what motivated you to come to the field of research in the field of environmental ecology? It was a long process of reasoning to come up with the idea of making these products. Perhaps the time to mark the change in my understanding of ecology as well as the ideas that led to these models was through a grant from the French project. People were given money to evaluate and learn about the production activities of the most advanced people in the field of ecology. I went to London and met some of the most advanced farmers in the field of ecology. At that time, I realized that a lot of knowledge that had been learned and was being applied at that time was not correct in the field of ecology. People did it differently. And based on what I observed, people combined their knowledge and experience in ecology. Because I was taught in Vietnam as well as encouraged to study ecology in the US. At that time, I learned a lot and it completely changed my view of ecology as well as led me to the ideas for this project. Although I had been teaching ecology since 2001-2002, in 2016, when the French gave me money, it was the first time I was sponsored to study ecology. At that time, I really found its beauty. The more I lived in the field of ecology, the more I learned about its value. I realized that the value of ecology is not only the desire to change something in the field of ecology in general, but it is also beneficial for me personally. Because I used to be very thin. I used to be thin all the time. However, after investing in these models, I can make them shine directly. For the past 4-5 years, I have not been thin. Currently, there are many concerns about environmental pollution, especially the pollution of waste, especially organic waste. Many people are very concerned because the processing of this waste is not yet fully effective. Is this part of the reason for experts to study more and create designs here? At the time of 2019, when I was successful in running the experiment model, the Chikamonic model, the results of the sanitation analysis at the Vietnamese Academy of Agriculture showed that vegetables are safe, even in terms of living standards in Vietnam. At that time, I confirmed that the system runs and does not need external interference. It runs very naturally. From the logic of the system, I thought that it could be completely applied to organic waste. Because at that time, there were a lot of articles that people reacted, blocking vehicles carrying waste I am also a person working in the field of environment, studying the environment, and teaching the environment at the academy. I think we need to do something for the environment. Based on the logic of the Chikamonic system, I developed a system called Kitchenphonics. At that time, I used organic waste directly to run the system. Because the previous advices that people pollute, pollute, it is not successful because it is too inconvenient for the people about the smell, about the pests, it is really inconvenient, so we are not successful. So the way we go helps the people to be cleaner, cleaner, and more convenient. You don't have to do anything with it, you just pour it into the system and let it run by itself. On vegetables, under birds, or under fish, with this ecological model, just a few square meters, the owner is free to use vegetables, eggs, or even fish. Dr. Pham Van Hoi said that this ecological model operates in the form of a tank, water pump, and air intake. They have a circular operating mechanism like a small garden. The goal of the system is to process a part of the organic waste that is easy to decompose from food, animals such as chickens, fish, and other plants. In order to increase the efficiency of production as well as environmental protection, we have to aim for a balanced system. In nature, this cycle system creates that balance. Of course, there are harmful animals, there are harmless animals, they coexist and control each other to create a harmonious system. However, when animals control each other, the harmful animals do not cause harm to humans or affect human health. Dr. Ho said that all components in ecological systems are carefully selected by scientists to play the highest role. With a fully automatic operating system, water in tanks does not need to be replenished with hygiene but still provides enough nutrients for plants. In particular, the use of fresh water directly nourishes the soil not only nourishes the plants, but also helps to improve soil fertility in an effective way. These seeds are earthworm seeds. They are light and do not absorb water. Because they do not absorb water, they help the system to circulate. The water is pumped up so that these seeds are fertile enough for the plants to grow. Secondly, it is the surface for the organisms to live here. A lot of organisms live here and it creates a process of decomposition of the fish's digestive system into a digestive system for the plants. At the same time, it creates oxygen, which creates a vacuum. You can imagine that when the tank is clogged, the oxygen will flow back into the water and return to the fish. In this model, the farmer can grow all kinds of herbs, as well as common vegetables. They all have high production and high quality, and have the same characteristic flavor. To create this system, I had to experiment and do it over and over again. During that process, what were the biggest challenges? The biggest challenge of this system is that we don't have a point to stick to. If someone teaches me how to do it, I can do it very quickly. But because it is so blurry and there is nothing clear, I have to fix it every day. It is a new discovery for me. There are hundreds of details and they are connected in a very logical way. So just a few details are not logical and the system will collapse. That's why it takes a lot of time. At the beginning, when I decided to do aquaponics, it took me 6 months. 6 months for the fish to die and 6 months for the vegetables to grow. It took me 6 months and I came here every day. At that time, I didn't understand the principle of water operation. Water is something that cannot be predicted. It is very hard to imagine. I didn't understand the function of the cycle. The cycle is like a river. It flows like that. It not only pushes the pollutants out. In the case of the cycle, it also returns clean water to the system. You said that you spent 6 months to research. In those 6 months, you didn't get any results. I don't know if the results are more successful than the old models. What motivated you to persist and achieve such a result? This is a question that I received for the first time related to the work I did This is called co-accident. It is a coincidence. In 2017, when I started this model, there were many difficulties. At that time, international NGO funds were allocated to Cambodia, Myanmar and Vietnam. At that time, I didn't have any project. When I didn't have any project, I was very free. When I was a child, I worked as a mechanic, electrician and so on. It motivated me to spend time on this. This is a siphon designed by Dr. Pham Van Hoi. Thanks to some improvements, this device not only pumps and discharges water automatically, but it also has many other functions. According to Dr. Hoi, this is the secret to successfully operate This is a siphon. It has been changed. If you go online, this is a siphon. But we have added this part. This part has many functions. The first function is to temporarily stop. The second function is to adjust it when the tree is small or big. The third function is to suck water. If it is only a siphon, after the operation is over, the tree will die. If we plant a tree and the roots of the tree go down here, the roots will not develop and even cause the tree to die. However, if we do it this way, the water will stop. The whole siphon will stop. So it provides the tree with an environment similar to planting soil. That's why we can plant many types of trees. After a lot of effort, hard work, day and night, you have successfully operated this system. How do you feel now? For me, I feel that I have never faced failure and I have never enjoyed success. Because when it runs, I continue to challenge with another idea. After analyzing everything, I came up with KitchenMonix. Then I came up with the All-in-One System. It integrates all functions. After that, I continued to develop. It is just a very small product in the process of exploration to have it. However, from the process of investment, running the model and understanding its structure, it is the only way to save the Tô-Lịch River. It is the most sustainable. Why? Because Hanoi needs two things. More green trees and the processing of the Tô-Lịch River. What we are doing is putting two things together to run it. We don't need to add any technology. We don't need to buy foreign chemicals. We don't need to buy foreign filters and processing systems. If this system is applied to the Tô-Lịch River, will it be successful? I experimented with the Tô-Lịch River and it surprised me. If we take the drinking water and leave it here for about two days, it will become cloudy. Because the water still contains chemicals and particles which make the water polluted. However, the water tank we experimented with the Tô-Lịch River was still the same after a week. It didn't change its color. The chemicals disappeared. Theoretically, the Tô-Lịch River is still running. We still have a lot of questions to ask. We can see that you are very passionate about environmental ecology. From the issue of waste to the issue of Tô-Lịch River, you have always been passionate. It can be seen that with your knowledge and passion, you have turned technology, as well as your knowledge into effective models and operations. Have you noticed that in addition to vegetables and leaves, we can successfully grow many kinds of trees and trees that grow very well. This has made the technology of Phan Van Hoi popular and many farmers in the city are enthusiastic about it. There is no more food in the garbage bag. For a year, Thuy's family always put it in these boxes. She said this is where she provides the model of Kitchen Pôn Hích that she is using. Every day in my life, I have a lot of food that I throw away. It will be a waste if I don't use it. I always struggle to remove the garbage that I throw away. With that thought, I found the model of the Center for Ecology of Thuy Hoi to be very useful for me and my family. There is also an advantage that this is a waste system so it will be used regularly. Even when I feel very busy and don't have much time to take care of it, it still ensures that the system provides enough nutrition for my plants. Kitchen Pôn Hích is one of many ecological models developed by Pham Van Hoi. This system also has operating systems like Chicken Pôn Hích, but the main difference is the organic matter that is thrown into the model. With this ecological model, I don't have to worry about the amount of food that I eat every day. What's more, my family and I still have clean, safe food and a place to relieve stress after working hours. This also helps us get high-quality food for our family and form a natural love between family members. However, what do you think we need to do to develop this model more effectively and expand it? I think we have to go back to many years ago when we were developing this ecological model. We had to invest a lot of money to develop it. This kind of investment is related to people's skills and the organic matter that is produced is not diverse enough and leads to bad watercress products. Watercress plants are usually planted with live vegetables and no one can grow their own products. If they fail, it's because of the quality. It's easy for you to understand that the quality of vegetables depends on the head. The better the nutrition, the better the vegetables. This system allows us to use the most diverse nutrition. When we say the most diverse nutrition, we sometimes forget that it comes from our family's waste. We throw away everything we eat from crab, fish, meat to soup. The vegetables are very good. It's not only the source of environmental protection to deal with pollution, but it also creates a very good quality of vegetables, chicken or fish for us. It's also an incentive for 60-year-old people to climb from level 1 to level 4 several times a day. It's a very good exercise and a very good motivation for us to stay healthy and love life more. We feel that what we are doing is meaningful not only for the environment but also for the future. Thank you. Thank you for the information you just shared. Hello, ladies and gentlemen. You are watching Diem Hien Khoa Hoc. In the third part, we will have a Q&A session with the experts. First of all, I would like to ask Mr. Hoang Thi Thanh. His phone number is 09753 and the last number is 923 in Hanoi. Recently, I have seen many articles about the concept of cycle. What is the cycle in agriculture and what are its benefits? Thank you. Your question is very broad. We can see that in nature, there are many types of trees and animals in agriculture and nature. The concept of cycle sometimes goes beyond the trees and animals that people are familiar with. For example, in the case of kitchen forage, to survive, there must be thousands of animals. It is very natural and we never analyze it. So, the concept of cycle is a system that connects and ensures a high biological level. The components are connected like the head of this component is the head of the other component or the waste of this component is the waste of the other component. So, when it comes to the concept of ecology, the concept of cycle, we can divide it into many levels. For example, a high cycle is a system or a full circular system. It is like the system that I have just shown you. It is like that. Although if we say that it is a complete cycle, it is not true. Why? Because we still have to use food from outside to feed the birds. We still use this waste to feed the birds. All systems are open. No system exists on this planet. However, the cycle is very high because we only feed the birds and sometimes we only use the waste. We can cycle a part like the system of fish farming. The fish release the rice. Or we can cycle a little more like the system of duck fish farming. It keeps increasing. For example, you can see that in the system, the more we diversify the ingredients with different functions in nature, the higher the cycle level and the more complicated it is. We have many kinds of trees, such as hydrangea, orchid, and other kinds of trees. We can integrate all of them in the system by using technology or simple labor to make the cycle run. In such a diverse system, the cycle level increases and becomes stronger. What are the benefits of such a system? If you listen to the owner of Jun Mai Hien farm in Phu Tho, he is from Germany and Poland. He has a hectare of farm and earns 4 billion VND per year. I was impressed by him. When he met German scientists, they asked him why he didn't come to Vietnam to be a farmer. Jun Mai Hien said he wanted to be rich only by using the cycle system. With the information shared by Mr. Ho, Ms. Thanh must be very excited to be able to be rich only by using the cycle system. My second question is about how to produce organic agriculture and prevent the spread of infectious diseases. That's a very good question. Many people ask the same question. I would like to ask Mr. Hiep about that. When you first came to Vietnam, what was your reaction? Before you came to Vietnam, you used to produce a lot of organic food. But when you came to Vietnam, the soil was not well-nourished and the plants were not well-nourished. Before you came to Vietnam, the soil was not well-nourished and the plants were not well-nourished. The plants were exposed to increased risk of diseases and the people continued to use pesticides. That led to food insecurity and poverty. When you moved to the organic farm, it took time for the environment to recover. For example, the president of the Lộc Thanh Commune, Lâm Đồng District, in 1992, Mr. Phát said that he didn't understand why his coffee was so many but the leaves were yellow. I asked him why the forest was so green so he decided to leave it as it was. He said that until 1996, the coffee was green so he decided to cut down the grass instead of leaving it as it was. He cut down the grass and started to invest to increase the yield to 4 tons per hectare. Another man, Mr. Cường Đức Trọng, I met him at the airport. He told me that he had been growing coffee since 1998. Mr. Đức Trọng grew coffee beans, coffee, lemongrass, and many other things. He said that it took him 2 years to plant the coffee because he had to water it. Mr. Đức Trọng also said that he had never used herbal medicine. When he was a farmer, he gave herbal medicine but he didn't use it because his coffee didn't get sick. We can say that when we grow organic coffee in a good environment, the disease won't develop and it will be controlled. He said that organic coffee needs time to change before it gets stronger. However, there is still a risk because the environment doesn't have boundaries. We do well in our environment but the pollutants and the source of the disease are all around us. To reduce the risk, Mr. Đức Trọng had to diversify his plants. For example, he had to plant and diversify his plants to make them stronger. Some of the production techniques are related to cotton. Cotton is like a baby. When a baby is born, from 0 to 3 years old, it determines his future. 0 to 3 years old determines his intelligence. The same thing applies to plants. The same applies to his plants. We have to pay attention to the quality of our plants. When we have healthy plants, we can fight the disease. With your detailed advice, I'm sure Mr. Nghiệp has learned a lot about how to produce organic agriculture effectively. Thank you for watching. Goodbye and see you again.
