Selection of Artificial Potting Media and Formulations of Fertilization for Camellia japonica

  • Received Date: 1990-05-22
  • Ten different kinds of artificial potting media used for the culture of Camellia japonica L. were mixed with vermiculite, saw-dust, river sand, peat and coal cinder. Two good mixed media, vermiculite:peat=2:1 and vermiculite:river sand: peat=10:5:1, in which the plants of C. japonica L. grew and bloomed excellently, have been obtained by means of three-year-culture experiments. Under the same level of applying micronutrients, seven fertilized treatments with different levels of N, P and K for the soiless culture were designed. The experiments showed that 23-12-15 formulation with high levels of N,P and K applied in spring and summer and 5-20-26 formulation with low level of N, and high levels of P and K applied in autumn and winter or 23-12-15 formulation with high levels of N, P and K applied once every twenty days throughout a year all can make the plants grow vigorously for a long time, bloom greatly and keep up their strong growing-potential in their limited potting media.

Abstract: Ten different kinds of artificial potting media used for the culture of Camellia japonica L. were mixed with vermiculite, saw-dust, river sand, peat and coal cinder. Two good mixed media, vermiculite:peat=2:1 and vermiculite:river sand: peat=10:5:1, in which the plants of C. japonica L. grew and bloomed excellently, have been obtained by means of three-year-culture experiments. Under the same level of applying micronutrients, seven fertilized treatments with different levels of N, P and K for the soiless culture were designed. The experiments showed that 23-12-15 formulation with high levels of N,P and K applied in spring and summer and 5-20-26 formulation with low level of N, and high levels of P and K applied in autumn and winter or 23-12-15 formulation with high levels of N, P and K applied once every twenty days throughout a year all can make the plants grow vigorously for a long time, bloom greatly and keep up their strong growing-potential in their limited potting media.
