Melon high-efficiency slow-release fertilizer with degerming insecticidal effects and preparation method

Abstract

The present invention belongs to the field of slow-release fertilizers, and specifically discloses a melon high-efficiency slow-release fertilizer with degerming insecticidal effects, the melon high-efficiency slow-release fertilizer with degerming insecticidal effects is characterized by comprising the following components in parts by weight: garlic polysaccharide sulfide derivative, attapulgite, polyvinyl alcohol, a crosslinking agent, polyglutamate hydrogel, mesoporous silica nanoparticles, salicylic acid, toosendanin, pyrethrum, tea polyphenols, composite microbial agents, sodium selenite, compound sodium nitrophenolate, viscous konjac flour, residue of furfural, brown sugar residue, and amino acids and the like. The garlic polysaccharide sulfide derivative and the attapulgite are used as basic coating materials, the micron size composite hydrogel prepared from the polyglutamate hydrogel and different sizes of mesoporous silica nanoparticle matters are added into the coating materials, the pore size of the coating materials are enriched, the dynamic slow-release performance and nutrient use efficiency of the fertilizer are improved, the fertilizer efficiency regulation property is ensured, the melon high-efficiency slow-release fertilizer promotes the melon to absorb and utilize different nutrients, and promotes the efficient cultivation.

Description

Technical field [0001] The invention belongs to the field of functional slow-release fertilizers, and particularly relates to a melon high-efficiency slow-release fertilizer with sterilization and insecticidal effects and a preparation method. Background technique [0002] Coated slow-release fertilizer has the effect of significantly improving fertilizer utilization. However, most of the slow-release fertilizers currently sold on the market face many problems, such as: 1. The coating material uses chemically synthesized non-degradable high molecular polymers. These non-degradable high molecular coating materials are easily left in agricultural use. The soil causes soil degradation and serious pollution; 2. The coating material uses natural polymer degradable materials, but the slow-release fertilizer prepared from these natural polymer degradable materials is too expensive on the one hand, and on the other hand, the controlled release effect is not good , With the degradation o...

AI Technical Summary

Problems solved by technology

[0003] The fertilizer efficiency of slow-release fertilizers depends on the slow-release material and the form of coating. It is common in the market to use the same or different coating materials to achieve layered coating and then achieve slow-release regulation, but this will increase material costs and production costs.
