Abstract

The invention relates to the field of agricultural fertilizers, in particular to a medium and trace element composition for a water-soluble fertilizer, the water-soluble fertilizer and preparations and application thereof. The medium and trace element composition comprises a medium and trace element, a thickening substance and an anti-frosting substance, wherein the medium and trace element comprises at least one of calcium, magnesium, iron, manganese, molybdenum, copper, zinc and boron; the thickening substance comprises at least one of polysaccharide thickeners and inorganic polymeric thickeners; the anti-frosting substance comprises at least one of alcohols and inorganic salts. The thickening substance contained in the medium and trace element composition can improve the blending performance and the stability of a finished product; the contained anti-frosting substance can improve the frosting resistance of a suspended water-soluble fertilizer as the finished product, so that the suspended water-soluble fertilizer does not separate out salt in the case of -20 DEG C. Through application of the formula of the medium and trace element composition, a pertinent customized fertilizer formula with different nutrient contents can be formed, so that different needs of different crops in different regions are met, and soil testing for formulated fertilization is achieved.

Description

technical field [0001] The present invention relates to the field of agricultural fertilizers, in particular to a medium-trace element composition for water-soluble fertilizer, water-soluble fertilizer and its preparation and application, in particular to a medium-trace element composition for suspension-type water-soluble fertilizer, water-soluble fertilizer and its preparation and application . Background technique [0002] As the direction of future fertilizer development, liquid water-soluble fertilizer has attracted widespread attention. Large-scale production of liquid water-soluble fertilizers is mainly made by dissolving nutrients, additives, and active ingredients through processes such as dissolution and chelation. After mass production, through packaging, transportation, sales agents at all levels, retail and other channels, it finally reaches the hands of farmers. The problems faced include: huge production investment, complex processing equipment, expensive pa...
