Abstract:The factors influencing Dendrocalamopsis oldhami container seedlings were studied using L9(34) orthogonal test and principal component analysis. The 4 factors adopted in the experiment were container types, container sizes, cultivation matrixs and fertilizer types, respectively, and every factor were set at 3 levels. The results showed that The 4 factors influencing the growth and shooting quantity of D. oldhami were ranked as fertilizer type > cultivation matrix > container size > container type, while fertilizer type and cultivation matrix played a decisive role in the quality of seedlings. The optimal combination of the 4 factors was: non-woven fabric container at the size of 25 cm×23 cm×23 cm (upper base diameter×bottom diameter×pot height) and with peat and perlite (7∶3) as the substrate, to which organic fertilizers were applied.
