Structure of recycled foam soilless culture system and its application in vegetable production

This paper described a new soilless culture system using foam as substrate. Foam substrate has good horticultural characteristics with light weight, high capacity of aeration, easy to handle, especially can be used for up to 10 crops. The nutrient solution of foam soilless culture system was recycled and disinfected by a bio-filter. The management of system and the cultivation practices used for tomato and bottle gourd were also presented in the paper.
