Abstract

The invention, belonging to the technical filed of agriculture, relates to a water-soluble fertilizer containing humic acid chelating multielement and a preparation method thereof. The water-soluble fertilizer is formed through a chelating process of raw materials, and the component of the raw materials comprises (by weight parts): 10 potassium humate powder containing more than 50 wt% humic acid, more than 50 wt% kali and no more than 3wt% water insolubles, 48-52 water, 7-24 macroelement compound, 4-18 mediumelement compound, 7.5-23.5 microelement compound, 2.5 beneficial element compound, 2rare earth element compound and 1.3-1.7 auxiliary agent. The preparation method includes seven steps. The water-soluble fertilizer has the advantages of complete nutrients, good compatibleness of nutrient elements, and high absorption and utilization of nutrient elements.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and specifically relates to a humic acid chelated multi-element water-soluble fertilizer and a preparation method thereof. Background technique: [0002] 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 " Water-soluble fertilizer containing humic acid "standard 3.1 definition of water-soluble fertilizer). [0003] Foliar fertilization is one of the important measures of modern agricultural production. With the development of science and technology, the water-soluble fertilizer products that use foliar fertilization as the main method are developing towards multi-element and multi-function. It provi...
