The invention provides a cultivation method allowing exacum affine to be flowery. Each liter of nutrient solution used by the method comprises 700-900mg of CaCl2.2H2O, 300-500mg of KNO3, 300-450mg of MgSO4.7H2O, 100-200mg of FeSO4.7H2O, 50-100mg of H3BO4, 150-200mg of CuSO4.5H2O, 250-350mg of ZnSO4.7H2O, 150-160mg of ammonium molybdate and 50-100mg of MnSO4.4H2O, and pH of the nutrient solution is adjusted to be 6.0-6.5. The exacum affine cultivated by the method has advantages in terms of flower shapes and especially in terms of plant heights, flower bud number and the like, the leaves of the exacum affine are bright green, the flowers of the exacum affine are bright-colored, and the ornamental value of the exacum affine is increased. |
