Problems solved by technology

[0004] At present, the humic acid-containing water-soluble fertilizers provided by the market are mainly produced according to the NY1106-2006 standard of the Ministry of Agriculture (that is, the "humic acid-containing water-soluble fertilizer" standard). The disadvantage of low crop absorption and utilization rate, so the research and development of active, efficient, economical, environmentally friendly, multi-element, multi-functional water-soluble fertilizers is the development direction

Abstract

The invention belongs to the technical field of agriculture, in particular relates to a water-soluble fertilizer by complexing humic acid with a plurality of nutrient elements and a preparation method thereof. The water-soluble fertilizer is prepared by complexing the following raw materials by weight parts: 8 parts of potassium humic acid powder containing more than or equal to 50 percent of humic acid component, more than or equal to 10 percent of potassium oxide component and less than or equal to 2 percent of water-insoluble substances, 42-46 parts of water, 33-38 parts of major element compound, 10 parts of trace element compound, 1.3-1.5 parts of additives and 1.8-2.5 parts of plant growth regulator. The preparation method comprises six steps. The water-soluble fertilizer has the advantages of complete nutrient elements, higher crop absorption utilization rate and stronger directivity.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a water-soluble fertilizer complexed with multiple nutritional elements by humic acid and a preparation method thereof. Background technique [0002] Combining irrigation to supply the nutrients needed by plants is called fertigation. The way of spraying is used to supply the nutrients needed by plants through leaves, stems and fruits, which is called foliar fertilization. Water-soluble fertilizers: liquid or solid fertilizers that are dissolved or diluted in water and used for irrigation and fertilization, foliar fertilization, soilless cultivation, soaking seeds and roots, etc. are called water-soluble fertilizers (water-soluble fertilizers are defined as the Ministry of Agriculture NY1106-2006 standard, namely " Humic acid-containing water-soluble fertilizer "standard 3.1 definition of water-soluble fertilizer). [0003] With the development of science and te...
