The invention discloses a jackfruit
fertilizer and a preparation method thereof. The jackfruit
fertilizer is prepared from the following raw materials in parts by weight: 15 to 21 parts of
urea, 12 to 19 parts of
calcium-magnesia
phosphate fertilizer, 13 to 20 parts of
potassium sulfate, 1 to 1.5 parts of
calcium silicate, 0.5 to 1 part of
magnesium sulfate, 1 to 1.5 parts of
potassium sulphate, 1 to 1.5 parts of
boric acid, 0.01 to 0.1 part of chelating
zinc, 0.01 to 0.1 part of chelating
copper, 0.01 to 0.1 part of
manganese sulfate heptahydrate, 0.01 to 0.1 part of
sodium molybdate, 0.01 to 0.1 part of
ferric trichloride, 0.1 to 0.2 part of
amino acid chelated
selenium, 30 to 50 parts of
organic matter, 1 to 2 parts of
amino acid, 3 to 5 parts of
humic acid, 0.5 to 1 part of fertilizer efficiency synergist, 1 to 2 parts of
soil conditioner and 0.5 to 1 part of long-acting and slow-releasing agent. Since the matching content of
nitrogen,
phosphorus and
potassium of the jackfruit fertilizer is reasonable, the jackfruit fertilizer contains the
organic matter, the
amino acid, the
humic acid, the medium element
calcium,
magnesium and
sulfur fertilizers, the
trace element boron,
zinc,
copper,
manganese,
molybdenum and
ferrous fertilizers, and the amino acid chelated
selenium fertilizer, and meanwhile, the jackfruit fertilizer contains the fertilizer efficiency synergist, the
soil conditioner and the long-acting and slow-releasing agent, on the basis that various
nutrient elements are provided, the effects of
nitrogen fixation,
phosphor activation and potassium releasing can also be achieved, and the defects of insufficient function, unreasonable
nutrient content and the like in the prior art are overcome.
