The invention discloses a special full-component biological
organic fertilizer for tobaccos and a preparation method of the special full-component biological
organic fertilizer. The
organic fertilizer is mainly prepared from the following raw materials in parts by weight: 26-38 parts of fermented
rapeseed cakes, 18-22 parts of
nitrogen fertilizers, 13-20 parts of
phosphorus fertilizers, 16-22 parts of
potassium fertilizers, 3-5 parts of
humic acid, 3-5 parts of
amino acid raw
powder, 2-4 parts of secondary and trace
nutrient elements, 1-3 parts of active
silicon fertilizers, 1-3 parts of rhizoma phragmitis, 2-3 parts of clove, 0.5-2 parts of functional microorganisms and 0.5-1 part of
nitrogen fertilizer synergists. The special full-component biological organic
fertilizer for the tobaccos is complete in product nutrients, and can meet the
nutrient elements needed for the growth of the tobaccos; components in a full-component biological organic
fertilizer product cooperate with one other and achieve synergism; the full-component biological organic fertilizer is easily absorbed by crops; the yield and the quality of
tobacco leaf can be obviously improved; the
rhizosphere microenvironment of the plants can be improved; the resistance of the crops can be improved; meanwhile, the application of chemical fertilizers can also be reduced; the quality of a
cultivated land can be improved.
