The invention discloses a special
fertilizer for planting of high-quality broccoli. The special
fertilizer is prepared from the following materials: celery leaves, radish peels,
fern roots, fungi residues, cow
manure,
chicken manure, radix patriniae heterophylla, mint leaves, rhizoma atractylodis, turtle shells, modified corncobs,
urea,
boric acid,
fulvic acid potassium,
sodium selenite,
ammonium phosphate,
ammonium chloride,
ferrous sulfate,
magnesium sulfate,
manganese sulfate,
sodium molybdate and
zinc molybdate. All compositions of the
fertilizer cooperate with one another and have a synergistic effect, so that rich and reasonable
nutrient substances are provided for the growth of the broccoli, and the
ecological environment of soil is improved and protected; meanwhile, common wastes are efficiently reutilized; finally, the yield of the finally-cultivated broccoli is improved by above 30 percent, the content of flavonoids in the cultivated broccoli is improved by 70-80 percent, the content of iron and
magnesium elements is improved by 20-25 percent, and the content of
iodine and
zinc elements is improved by 15-20 percent, therefore, the special fertilizer has a good edible value.
