摘　　要：透气型砂栽培(Sandponics)是生态环保、低成本、低技术的无土栽培技术,符合当前中国国情和世界无土栽培发展趋势。阐明透气型砂栽培系统的组成结构,提出透气型砂栽培基质的粒径、含盐量、含泥量和酸碱度等理化指标,探讨砂栽培营养液元素种类和要求,分析透气型砂栽培生产可持续性理论基础,建立透气型砂栽培技术标准,为透气型砂栽培的进一步研究和生产实践提供参考。分析透气型砂栽培蔬菜产品的含糖量、亚硝酸盐含量、重金属含量等营养品质。总结透气型砂栽培的特点和所具备的生态意义、社会意义,分析透气型砂栽培在都市农业和南海岛屿蔬菜生产实践中的应用前景。Sandponics, an eco-friendly, low-cost, low-tech soilless cultivation technique, accords with national condition of China and soilless culture development of world. The paper illuminates the Sandponics system composition and states sand substrates indexes including particle size, salt content, mud content and acidity-alkalinity. Element requirements of nutrient solution is explored and sustainable theory of the Sandponics is analyzed. The paper builds up the Sandponics technique standard to provide reference for production practices and future studies. The paper analyzes nutritional quality of vegetables cultured with the Sandponics, including sugar content, nitrite content and heavy metal content. The characteristics of the Sandponics and its ecological significance and social significance were claimed. The paper analyzes the prospect of the Sandponics in the Urban Agriculture and the South Sea Islands.
