Study On Selection Of Growing Subsrate For Lily

This study was focus on the selection of culture matrix for two Orieatal lily varieties, Acapulco and Acapulco. garden mould, peat, sawdust and mushroom residue were used as subsrate material respectively. The experiments were designed as random projects and were carried out in YangLing and Xi'an during December 2003 to April, 2005. The effects of different growing matrix on lily growth rate, leaves and flowers quality were compared. To screen the optimal subsrate for lily growth and development, the data were analyzed by ANOVA analysis, LSR multiple comparisons and correlation analysis with DPS software. The conclusive results were obtained as following.Acapulco was a much better lily variety than Sorbone for cultivation in Northwest China, showing a better growth performance, superior leaves and cut flower qualities , Acapulco also have large flower,bright color,long and thick stem, more flower number.The best growth performances and flower qualities were observed for the growth of the two varieties in subsrate T₁ (peat), than in subsrate T₄(the mixture of peat, mushroom residue and sawdust in the volume ratio of 1:1:1) and than in matrix T₆(the mixture of peat, mushroom debris and garden mould, in the volume ratio of 1:1:1). And the worst growth performance of lily was found in T₇(the mixture of peat, mushroom residue and garden mould, in the volume ratio of 1:2:1). Considering that peat was not a recycled resource with a higher value, which was not the optimal growth subsrate for lily, but the two mixture subsrate T₄ and T₆ available readily and with acceptable price can be used as economic and applicable culture subsrate for lily.Through correlation analysis, some physicochemical factors of subsrate, which showed close relationship between lily growth performances, were screened, including pH, capacity density, porosity and organic matter content. Our results suggested to some extent of lily growth the lower capacity density, smaller pH value, and larger total porosity, larger aeration porosity and higher organic matter content, the better growth performance the lily was.
