Studies on the Fertilization of Zantedeschia
For experiment 1, Best Gold cultivar planted in a simple housing rooged with PE material and bagasse compost used as growing medium (40 cm depth) during 17 November, 1995 to 3 May , 1996. Results showed that under the range of nitrogen used, the fresh weight of tubers is linear related to nitrogon rate at highly significant level. The distribution of nutrients indicated that the rate of fertilizers shall be higher than applied in this experiment.For experiment 2, Z. cultivar Blackmagic and Z. cultivar Jaquelien planted in a field located at Sue-Yuan, 40 cm depth of artifical medium during 10 May, to 14 October, 1996.Results suggested that fertilizers applied in liquid solution raised the length of cut flowers 15-20% and the height of plant 33-42 %.The concertration of P,K,Mg,Fe and Mn of their tubers were also higher at significant level at dormancy stage, but the fresh weight of their tubers were lowered 15-20% than of solid fertilizers''.
