The results showed that composition 4 （black turf 1.2 L＋vermiculite 0.3 L＋ceramsite 0 L） is not suitable for the cultivation of indoor lawns. Composition 1 （black turf 0.3 L＋vermiculite 0.75 L＋ceramsite 0.45 L） and composition 2 （black turf 0.6 L＋vermiculite 0.6 L＋ceramsite 0.3 L） are suitable for indoor cultivation of F. rubra; and Perennial L. perenne turned yellow in all the tested media, and therefore, the media tested in this study are not suitable for indoor cultivation of Perennial L. perenne.展开更多
