The invention belongs to the technical field of
crop planting, and particularly relates to a
fertilizer composition for promoting fruit setting of winter jujubes and a fertilizing method of the
fertilizer composition. The
fertilizer composition for promoting fruit setting of winter jujubes is divided into a composition A, a
composition B, a
composition C and a composition D, each of the combination A, the combination B, the combination C and the combination D comprises two or more fertilizers rich in
plant signal conduction substances; the fertilizer rich in the
plant signal conduction substance at least comprises a
signal conduction element; the combination D further comprises a
plant growth regulator.
Fertilizer combinations containing different plant
signal transduction agents are applied in different growth stages of the winter jujubes, reasonable distribution of
plant nutrition is adjusted through the plant
signal transduction agents, so that robust flower buds are cultivated, dominant fruits are prominent after fruit setting, meanwhile, the dominant winter jujubes are rapidly expanded through
nutrition competition, inferior fruits are automatically eliminated, and the quality of the winter jujubes is improved. Overall winter
jujube fruit setting is uniform and loose, and the fruit
thinning cost of farmers in the later period is reduced by 50% or above.
