Abstract

The invention relates to the technical field of fertilizers, specifically to a functional compound fertilizer and a preparation method thereof. The functional compound fertilizer disclosed by the invention comprises a functional auxiliary agent. The functional auxiliary agent comprises the following raw materials in parts by weight: 0.1 to 0.6 part of biochar powder, 0.1 to 0.6 part of ammonium polyphosphate, 0.1 to 0.6 part of sorbitol, 0.1 to 0.6 part of medical stone, 0.07 to 0.3 part of algal acid, 0.07 to 0.3 part of alginic acid, 0.07 to 0.3 part of mannitol, 0.07 to 0.3 part of cellulose and 0.07 to 0.3 part of betaine. The functional compound fertilizer provided by the invention also comprises chelated medium trace elements and an anti-hardening agent. The preparation method of thefunctional compound fertilizer comprises the following steps: weighing of the above raw materials; mixing; crushing; sieving; and granulating. According to the functional compound fertilizer, production cost can be greatly reduced, the functions of the functional compound fertilizer are rich, and the utilization rate of the fertilizer is further increased; and the functional compound fertilizer is simple and convenient in production process and environment-friendly, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a functional compound fertilizer and a preparation method thereof. Background technique [0002] In recent years, the functional fertilizer industry has developed rapidly. However, traditional functional fertilizers generally have problems such as relatively high production costs, lack of product types, single product functions, and unstable product effects, which greatly reduce their use in agricultural food production. promotional application. [0003] With the implementation of the zero-growth action plan for chemical fertilizer use, functional compound fertilizers suitable for the development of modern and efficient ecological agriculture have gradually received more and more attention. Therefore, it is urgent to develop and apply functional compound fertilizers to further improve fertilizer efficiency, improve the utilization rate of fertilizer nutrient resources, and p...
