Sustained-release carrier particles and preparation method thereof

Abstract

The invention belongs to the technical field of plant growing supplies, and particularly relates to sustained-release carrier particles and a preparation method thereof. The sustained-release carrierparticles are prepared from paper powder, fillers, binders, sustained-release agents and auxiliary materials, wherein the auxiliary materials include anti-foaming agents, bactericides and emulsifiers.The sustained-release carrier particles made from the paper powder have the advantages of strong adsorption capacity, slow release speed, and capability of preventing soil hardening and meeting growth requirements of plants such as crops; the preparation method includes the steps of pulverizing, mixing, extruding, molding, barreling, drying and the like, and is simple, and short in time consumption.

Description

technical field [0001] The invention belongs to the technical field of plant planting supplies, and in particular relates to a slow-release carrier particle and a preparation method thereof. Background technique [0002] Carrier particles refer to the granular substances used to load pesticides, nutrients, and fertilizers during the planting and cultivation of crops and other plants. They generally have a porous structure and good adsorption capacity. After loading pesticides, nutrients, or fertilizers, they are Placed in the planting area of ​​crops and other plants, it releases pesticides, nutrients or fertilizers to improve the growth quality or speed of crops and other plants. [0003] The granular carrier used for loading pesticides is also called pesticide carrier, which is also a kind of pesticide adjuvant. The pesticide carrier has a special crystal structure and excellent physical properties, and has a large specific surface area, strong adsorption force, good suspe...

AI Technical Summary

Problems solved by technology

[0005] However, the particle carrier in the prior art has the following defects: 1, the adsorption capacity is limited, and the release speed is fast, it is easy to cause crop phytotoxicity, or soil compaction, it is difficult to meet the growth requirements of plants such as crops; 2, most of them are made of mineral soil Or slag as the main raw material, the extensive use of mineral resources consumes non-renewable resources and damages the environment

However, the defects of this technology are: 1. After the humic acid and the filler are evenly mixed, the humic acid fills the gaps of the filler, and the carrier has limited load capacity for substances such as pesticides and plant influencers; 2. The overall production process It needs to be fermented for more than 7 days, which takes a long time
