Abstract

The invention discloses a method applied to efficient suspension liquid fertilizer containing fulvic acid for lettuce. The suspension liquid fertilizer includes, by weight, 10-25 parts of fulvic acid, 35-50 parts of major element, 1-10 parts of medium element, 0.2-3 parts of trace element, 0-3 parts of functional substance, 3-5 parts of suspended aid, 2-12 parts of a composite chelating agent, 0-1 parts of a defoaming agent, 0-1 parts of solution stabilizer, and a thickener. The preparation method comprises the steps of: adding water, potassium humate, nitrogen fertilizer and potassium fertilizer into a reactor A, and conducting high-speed stirring to prepare a saturated mother liquor; adding water, phosphate fertilizer, trace element material, a dispersing agent, a filler and partial defoaming agent into a reactor B, conducting high-speed stirring and grinding for the formation of a solid-liquid mixture; mixing the saturated mother liquor and solid-liquid the mixture, adding a thickening agent, residual defoaming agent and an anti-freezer, and emulsifying to prepare a suspension liquid fertilizer. The invention has the advantages of high total nutrient content, no layering or deposition, and realization of long distance transportation.

Description

technical field [0001] The invention relates to a suspension liquid fertilizer, in particular to the technical field of preparation of a suspension liquid fertilizer. Background technique [0002] Water is the carrier for crop roots to absorb fertilizers. If water can be replenished in time during fertilization, fertilizer and water can be replenished to crop roots together. Modern agricultural powers use water and fertilizer integration technology to solve the problem of fertilizer absorption efficiency of crop roots. Water and fertilizer integration technology is liquid fertilizer. Liquid fertilizers include clear liquid fertilizers and suspension fertilizers. Clear liquid fertilizers have many advantages of liquid fertilizers, but at the same time they have a big disadvantage - low nutrient content. Most mature clear liquid fertilizer formulas contain Between 15% and 25%, limit the transportation distance of clear liquid fertilizer. The suspension liquid fertilizer is ...
