The invention belongs to the technical field of pepper planting, and particularly relates to a fertilizing method for improving the
vitamin content of green peppers. The method specifically comprisesthe following steps that root application is carried out once with fermented grape
skin residue liquid at the middle stage of seedlings and the later stage of the seedlings separately; and foliage spray is carried out once with a
nutrient solution in the early
flowering season, wherein the
nutrient solution is prepared from the following raw materials: fermented mulberry juice,
citric acid chelated
magnesium, bamboo leaf
polysaccharide, spirulina
polysaccharide,
puerarin,
gallic acid,
ferrous sulfate and water. The method has the advantages that the division, differentiation and growth of roottissues are effectively promoted, the
branch growth and the strong growth of a
root system are promoted, the
utilization rate of
soil nutrients is increased, so that the seedlings of
green pepper plants are thick and strong, the growth of leaves are vigorous, decay and fall of flowers are effectively inhibited, rapid synthesis of
chlorophyll of the leaves is promoted, the
photosynthesis efficiency is improved, in addition, the growth and the expansion of the green peppers are effectively promoted, the contents of
folic acid,
vitamin A,
vitamin E,
vitamin B1 and other vitamins of the green peppers are remarkably improved, so that the
nutritive values of the green peppers are improved.
