This invention discloses a
bud-promoting
humic acid compound liquid
fertilizer formulation and its preparation method suitable for cotton, relating to the field of agricultural
fertilizer technology. The formulation, based on the preparation of 1000 parts by weight of the finished product, consists of the following
raw material components in parts by weight: 700-750 parts by weight of water, 40-50 parts by weight of
potassium hydroxide, 140-160 parts by weight of
potassium dihydrogen
phosphate, 80-100 parts by weight of
urea, 65-75 parts by weight of mineral-derived
potassium humate, 8-10 parts by weight of
alkyl glycoside-
rhamnolipid composite bio-penetrating agent solution, and
polyaspartic acid- The
fertilizer formula comprises 10-14 parts by weight of γ-
aminobutyric acid (GABA) compound functional liquid, 15-25 parts by weight of mineral-derived potassium humate, 5-10 parts by weight of
plant-derived compound amino acids, 3-6 parts by weight of EDTA chelated micro-fertilizer, 2-5 parts by weight of
seaweed extract, and 1-3 parts by weight of
polyethylene glycol-based
wetting and spreading agent. This invention designs a fertilizer formula that meets the needs of cotton during the
budding stage, achieving a
dual function of
nutrient supply and physiological regulation. A refined preparation process ensures the fertilizer is uniform and stable, suitable for large-scale production, and retains active ingredients, ensuring stable application effects.
