Fish farming does not change the water, grow vegetables without fertilizing! Changping Agriculture i

　　In May of this year, Beijing Fukuda Agricultural Technology Co., Ltd. developed a set of "fish and vegetable symbiosis" cyclic ecosystem for production which took nearly 5 years to formally land in Changping and conduct adaptation experiments. The R&D team hopes to screen out the types of fish and vegetables that are truly suitable for local production and sales within one year, and strive to build Changping into a distinctive fish and vegetable symbiosis supply base, and provide safe and assured food for the people.

　　The founder of the project, Zhu Wei, introduced that "fish and vegetable symbiosis" as a new type of composite work technology is a virtuous cycle ecosystem that organically combines aquaculture and hydroponic cultivation technology, and realizes intelligent management with the help of computer information and automatic control technology. , So as to realize the harmonious symbiosis benefits of fish farming without changing water, growing vegetables without fertilizing, and enabling animals and plants to thrive. The whole system has the characteristics of environmental protection and energy saving, green and organic products, high yield and high return.

　　在In traditional planting and breeding industries, farmers use chemical fertilizers to increase production, spray pesticides to reduce pests, and farmers use fertilizer and water to feed them in pursuit of high yields, which cause a certain degree of pollution to the soil and the surrounding environment. “This system transforms the fish manure produced in the fish pond to make it the nutrient needed by the plant, enters the vegetable pond cycle, and makes the vegetable pond a purification area for fish manure, and then absorbs it through the plant roots, leaving a clean The water returns to the fish pond to form an ecological cycle of balanced transfer of biological nutrients. In this way, the fish can be cultured at a high density, the yield is higher than that of pure culture, and there is no sewage discharge. "Zhu Wei introduced that because fish and vegetables do not need to touch the land or fertilize during the production process, heavy metal pollutants, diseases and insect pests will not threaten plants, that is, there is no need to spray pesticides during the growth of vegetables, and what you get is green organic vegetables. .

　　according to Understand that in the "fish and vegetable symbiosis" system, all plants grow on the water surface without separate watering; fish manure provides nourishment without separate fertilization, and water consumption can only be carried out through natural evaporation or plant absorption, which is more than traditional agriculture In other words, the water saving rate exceeds 90%. In addition, the entire system can adjust the size of the equipment according to the area of ​​the existing greenhouse, and can effectively use existing resources such as idle greenhouse. The daily maintenance of the three sheds requires only one worker, which greatly reduces labor costs.

　　In terms of production varieties, Zhu Wei Said: “After half a year of experimentation, we have eliminated leeks, spinach, loofah and other products as vegetables. At present, tomatoes, cucumbers, water spinach, and peppers can ensure stable production. Suitable for local farming are grass carp and sturgeon, which are in line with market demand. Mandarin fish is in the process of experimentation. ”

　　It is reported , This project won the 4th "China Chuangyi" Entrepreneurship Innovation Competition Excellence Award in Beijing Trial and the third prize of the Modern Agriculture Group in the 2020 Beijing Veterans Entrepreneurship Innovation Competition. "The Fifth Plenary Session of the Nineteenth Central Committee of the Communist Party of China proposed to give priority to the development of agriculture and rural areas, and the "fish and vegetable symbiosis" project can win a national competition, indicating that the project has been recognized by experts. At present, we are also continuing to pay attention to this project and steadily advancing it, hoping to help the development of Changping's agriculture and increase the sending and receiving capabilities of farmers. "The Secretary of the Agricultural and Industrial Committee of the Changping District Committee said.

　　“We plan to end The existing six sheds were fully equipped with production capacity, and the finalization of the system "Beijing Changping Model" was completed. In the next step, we plan to cooperate with some towns and villages in Changping to further promote this production system, so that it will "light up and heat up" and provide more healthy food for the people's table. "Zhu Wei said.
