Abstract

The invention relates to a yellowish-brown humic acid-containing water-soluble fertilizer and a preparation method thereof. The preparation method comprises the following steps of 1, raw material quantitative proportioning, 2, reaction, 3, assistant addition, 4, stirring, 5, reaction, 6, cooling, and 7, packaging. The yellowish-brown humic acid-containing water-soluble fertilizer has total humic acid content greater than or equal to 40g / L, total nitrogen content greater than or equal to 80g / L, phosphoric pentoxide content greater than or equal to 40g / L, potassium oxide content greater than or equal to 80g / L, total trace element content greater than or equal to 60g / L, and water-insoluble substance content less than or equal to 50g / L. Potassium yellowish-brown humate, and macroelements and trace element necessary for plant growth are prepared into the yellowish-brown humic acid-containing water-soluble fertilizer. The yellowish-brown humic acid-containing water-soluble fertilizer has the advantages of high activity, comprehensive and balanced nutrition, high utilization rate, high hard water resistance, no flocculation, no deposition, and spray and drop irrigation adaptability. The yellowish-brown humic acid-containing water-soluble fertilizer can be widely used for a plurality of crops and can be directly sprayed on crop blade faces or punched and dropped on crop roots.

Description

technical field [0001] The invention belongs to the type of agricultural fertilizer and is a humic acid organic water-soluble fertilizer, in particular to a water-soluble fertilizer containing yellow-brown humic acid and a preparation method thereof. Background technique [0002] Long before chemical fertilizers were used in agricultural production, Chinese farmers mainly relied on the application of organic farmyard manure to increase crop production. After the advent of chemical fertilizers, due to their high nutrient content, the effect of increasing crop yields is remarkable, and they are easy to use, thus forming the habit of using chemical fertilizers alone. However, with the excessive use of inorganic fertilizers, the damage to soil and crops is becoming more and more serious. Some areas have caused soil quality degradation, soil compaction, poor tillability, decreased water and fertilizer retention and air permeability, and reduced soil organic matter content. Long-...
