Humic acid fertilizer special for rosa chinensis and preparation method of humic acid fertilizer

Abstract

The invention discloses a humic acid fertilizer special for rosa chinensis and a preparation method of the humic acid fertilizer. The humic acid fertilizer is composed of quantitative humic acid, peat, sesame dregs, decomposed chicken manure, nitrogen-phosphorus-potassium fertilizer, mixed medium and trace elements and traditional Chinese medicine composition. The preparation method comprises the following steps: utilizing existing materials that are commonly used in gardens; adding the humic acid, a variety of medium and trace elements and the traditional Chinese medicine composition; performing the physical extrusion granulation to produce the fertilizer capable of meeting a fertilizer requirement law of rosa chinensis and also prolonging fertilizer effect release time, wherein the utilization rate of the fertilizer is increased. Meanwhile, crude fiber-containing organic fertilizer and chemical fertilizer particles are prepared into columns, thereby avoiding using a binder, reducing a contact area of the fertilizer and water, playing a role of slow release, increasing the utilization rate of the fertilizer, improving fertilizer retaining and supplying conditions of the soil, increasing the number of flowers of rosa chinensis and prolonging the flowering period; the preparation method is simple and feasible, and suitable for large-scale mechanized production.

Description

technical field [0001] The invention relates to the production field of organic fertilizers, in particular to a special humic acid fertilizer for roses and a preparation method thereof. Background technique [0002] Rose (Rosachinensis) originates in my country, is a traditional famous flower of my country, and is now cultivated all over the country. Rose is a fertilizer-loving flower that requires a lot of fertilizer. If nutrients are not replenished in time, the flowering period will be shortened, the flowers will be less, and the flowers will be small, which will seriously affect the ornamental value. [0003] For a long time, in the field of gardening in my country, there have been problems of applying simple chemical fertilizers, original organic fertilizers, special fertilizers for agriculture and special fertilizers for vegetables, and low nutrient utilization efficiency of fertilizers. [0004] Humic Acid (HA for short) is a polymer substance. According to experimen...

AI Technical Summary

Problems solved by technology

At present, humic acid fertilizers have been initially applied on garden trees and lawns, but there are relatively few studies on the application of humic acid fertilizers on roses.

[0005] In addition, in the production process, humic acid is mainly crushed into fine powder and added to binder for disc granulation, or humic acid is treated with acid and alkali to make liquid fertilizer, but it is mixed with long fiber raw materials. There are not many studies on combination, processing without adding binders, coal-fired drying cannot be carried out in megacities, and how to prolong the slow-release effect of fertilizers
