Foam substra te has g oodho rticultural characteristics with lig ht w eight, hig h capacity of aeration, easy to handle, especially can be usedfo r up to 10 cro ps. The nutrient solutio n of fo am soilless culture system w as recycled and disinfected by a bio-filter. The ma nagement of sy stem and the cultiva tion practices used for toma to and bo ttle g ourd were alsopresented in the paper.Key words: foam substrate; soilless culture; ho rticulture; drip irrig atio n; bio -filter231 9 <·½w©:ÖÌ TZ åÉ ¡ ! ² ?¥ùîШ
