Abstract:

To select the best culture medium of Zantedeschia hybrida ‘Black Magic’, in this paper, orchard soil as control, four mediums that made of peat, perlite, vermiculite and sand in different volumetric proportions were tested. The physical and chemical properties and growth characteristics data of ‘Black magic’ were measured. The results showed that the nutritionally balanced medium which porosity of between 65%-80% and pH between 5.0-6.7, was the best medium for ‘Black Magic’. Seedling stage and bud stage of 'black magic' cultivated in treatment D peat︰perlite︰vermiculite︰sand=3︰1︰1︰1 were the most shortest, means were 52.7 days and 10.3 days. Blooming date was the longest, reaching a mean of 31 days. Flower number of single corm reached a maximum of two. This paper used four treatments, in addition to outstanding performance in treatment D, the other treatment with the poor performance, to be further improved.
