Potassium-enriched organic slow-release compound fertilizer

Abstract

The invention adopts the technical scheme as follows: a potassium-enriched organic slow-release compound fertilizer comprises the following components: 1-3% of amino acid chelated microelement, 1-5% of humic acid, 0.1-0.5% of nitrogen-fixing bacteria, 0.2-1.5% of pesticide, 1-4% of water-soluble organosilicone, 15-35% of urea, 2-8% of ammonium dihydrogen phosphate, 1-5% of nitrogen-pyridine, 1-5% of plant ash and the balance of crushed straw, wherein the amino acid chelated microelement provides metal microelements for crop growth; the humic acid improves the fertilizer efficiency, improves soil, stimulates the crop growth and improves the quality of agricultural products; the nitrogen-fixing bacteria increase the using efficiency of nitrogen element and improve the fertilizer efficiency; the pesticide avoids a plague of insects; the organosilicone adsorbs the fertilizer to form slow release to a certain degree; the urea provides a nitrogen fertilizer for crops; the ammonium dihydrogen phosphate provides a phosphate fertilizer and a nitrogen fertilizer for the crops; the nitrogen-pyridine plays a nitrogen-fixing role, reduces the loss of the nitrogen fertilizer and enhances the fertilizer efficiency; the plant ash provides potassium and other microelements for the crops and enhances the fertilizer efficiency; the crushed straw is a basic fertilizer of the potassium-enriched organic slow-release compound fertilizer. The potassium-enriched organic slow-release compound fertilizer is conducive to circular economy, helps to reduce the using amount of a conventional fertilizer, and can recuperate soil.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a potassium-rich organic slow-release compound fertilizer and a production process thereof. Background technique [0002] The current fertilizers in my country are mainly a mixture of macroelements, medium and microelements and additives. The content of trace elements is low, and it is not a slow-release fertilizer. The fertilizer efficiency is poor, the scope of application is narrow, and the types of crops suitable for it are also limited. In recent years, with the continuous increase in the application of compound fertilizers in production, the production ratio of compound fertilizers is unreasonable, and the phenomenon of unreasonable use of compound fertilizers has become increasingly prominent, resulting in high production costs and low content of compound fertilizers, especially Potassium content is insufficient, it is easy to make the soil harden, which gradually affects the yield and qual...
