[Explanation] The balcony is full of fresh vegetables, and the vegetable’s nourishment comes from the fish pond downstairs... Recently, in a high-rise housing under construction in Xin'an Village, Shuangliu District, Chengdu, a model building of "Smart Carbon Neutral Ecological Value System" under construction.
The reporter learned that the system creates low-carbon agriculture through "vegetable fields in the sky" and "underground fish ponds", which can significantly reduce carbon emissions.
The reporter walked to the model platform and saw that the two sides of the spacious balcony were full of fruits and vegetables. The outside was soil-grown fruits and vegetables, and the internal test was hydroponic fruits and vegetables, including peppers, greens, and apples.
And the water source for the hydroponics of the "air vegetable garden" on the balcony comes from the fish pond on the first floor.

The fish manure and fish bait are transported to the hydroponic plant planting box through the entire system, and then the ammonia nitrogen in the hydroponic plant planting box is absorbed and utilized by the hydroponic plant, and after the organic or inorganic nutrients such as ammonia nitrogen are absorbed, The water body is purified, and the purified water body is returned to the factory fish pond through the pipe network, and then the water in the fish pond is efficiently used.
[Explanation] The reporter observed that different vegetables are illuminated by different light sources, some are white, some are purple, light sources are light strips, circular lights, and fluorescent lights.
The technical person in charge of the R&D party told reporters that the "Air Vegetable Garden" uses the most popular artificial light source and drip irrigation technology.

After accurate measurement, the drip irrigation method (cultivation) is adopted. The first aspect of this method can ensure the integration of water and fertilizer, the supply of nutrients, and also ensure that the efficiency of water use in the production process is maximized.
The light of leafy vegetables and fruits and vegetables adopts different light sources, which are different from the light sources below, which not only ensures energy saving, but also meets the light needs of different plants.
[Explanation] Regarding the fertilizer supply and other issues of the "Vegetable Garden in the Air", the person in charge of the research and development party said that in the future overall design, a recycling system for residents' domestic sewage and kitchen waste will be built to provide for the growth of fruits, vegetables and green plants. The needed irrigation water, fertilizer, and cultivated fruits and vegetables can be eaten directly, thus building a recyclable green ecological cycle chain.

The current project site covers an area of more than 200 square meters agro-ecological platform, a 6-story model building, and it is calculated that the "landing" can reach 5 acres of arable land.
After the organic waste is treated and converted on-site through this system, carbon emissions in the process of organic waste treatment and processes can be reduced.
[Explanation] In addition to this "Smart Ecological Value System" model building, in order to achieve agricultural "carbon reduction", the test area also has a vacuum toilet system covering a radius of 5 kilometers, a biogas system with a daily output of 300 cubic meters, and an annual output of 6,000 tons. The organic fertilizer production center, the organic production experimental area and the "four-in-one" agricultural exhibition area can realize the on-site treatment and reuse of organic waste and sewage.
