The invention relates to the technical field of
plant cultivation, in particular to a fertilizing method of top
grafting hybrid citrus of
citrus unshiu. The fertilizing method comprises the following steps:
germination fertilization, fruit stabilizing fertilization, fruit expanding and
branch promoting fertilization, and fruit picking fertilization; an organic bio-
fertilizer is adopted, therefore comprehensive
nutrition is achieved, full
nutrition absorption is facilitated, the
bioavailability of the rural
organic fertilizer is improved, the uniformity of the
fertilizer is facilitated by different fertilization positions and annular furrow application at water dropping parts on the periphery of the tree-crown, full absorption of the organic bio-
fertilizer can be ensured, and at the same time, the damage to the
root system can be reduced. With the adoption of the fertilizing method of top
grafting hybrid citrus of
citrus unshiu, provided by the invention, the percentage of fertile fruit and the yield per
plant of top
grafting hybrid citrus of
citrus unshiu are increased, the soluble
solid of fruits is improved, the
sugar-acid ratio is increased, higher
economic benefits are achieved, and the fertilizing method is suitable for popularization and application.
