Problems solved by technology

[0005] Aiming at the problems that the existing water-soluble fertilizer with a large amount of elements is a powder, it is inconvenient to spread, the duration of effect is short, and the frequency of fertilization is many; the water-soluble fertilizer with a large amount of elements in the powder cannot be granulated or granulated without adding a large amount of binders. , the present invention aims to provide a kind of granule water-soluble fertilizer with a large amount of elements, which solves the granulation problem of water-soluble fertilizer with a large amount of elements through ATOP solution. Etc., suitable for various fertilization needs; high nutrient content, less fertilization per mu, saving labor costs; fully water-soluble and fast dissolving speed, reducing nutrient loss and providing nutrients more quickly

Abstract

The invention provides a granular macroelement water-soluble fertilizer. The granular macroelement water-soluble fertilizer comprises nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, trace element fertilizers and ATOP solution. The ATOP solution accounts for 3%-5% of the total quantity of the granular macroelement water-soluble fertilizer and is compound solution of polyhydroxyl aldehyde, water-soluble binders and dispersing agents, and a mass ratio of water to the polyhydroxyl aldehyde to the water-soluble binders to the dispersing agents is (55-65):(35-45):(0.8-1.2):(0.8-1.2). The invention further provides a method for preparing the granular macroelement water-soluble fertilizer. The granular macroelement water-soluble fertilizer and the method have the advantages that macroelement water-soluble fertilizers can be granulated by the aid of the ATOP solution, components in the high-content granular macroelement water-soluble fertilizer manufactured by the aid of the method can be completely dissolved in water, accordingly, the solubility of the granular macroelement water-soluble fertilizer can be improved, the granular macroelement water-soluble fertilizer canbe quickly dissolved and absorbed after being applied by users, the utilization rate of the granular macroelement water-soluble fertilizer can be increased, the lasting time of the granular macroelement water-soluble fertilizer can be prolonged, and nutrients can be persistently supplied; the granular macroelement water-soluble fertilizer is convenient to use, top dressing can be particularly pertinently carried out by the granular macroelement water-soluble fertilizer for planting fruit trees, labor force can be reduced, and the labor cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a granular macroelement water-soluble fertilizer. Background technique [0002] With the continuous development of modern agricultural technology, people's understanding of fertilizers has been continuously improved. While paying attention to the absorption and utilization of fertilizers, they are also concerned about the pollution of the soil environment. Soil acidification, compaction, and salinization have become key issues restricting agricultural development. At the same time, the requirements for the cheapness of fertilizer products are getting higher and higher. Especially for the planting of fruit trees, it is often accompanied by difficulties in watering in mountainous areas, so fertilization is generally selected as the main method of fertilization. Spreading topdressing has very high requirements on the form, dosage and absorption utilization rate of f...
