Abstract:

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.

Key words: Sandponics, substrates, nutrient solution, nutritional quality
