Preparation method of solid fertilizer for preventing root ageing and root rot

Abstract

The invention relates to the technical field of organic fertilizer, in particular to a preparation method of solid fertilizer for preventing root ageing and root rot. The solid fertilizer for preventing root ageing and root rot comprises the following components in parts by mass: 100 to 120 parts of organic compound fertilizer, 20 to 30 parts of an organic macromolecule nucleating agent, 20 to 25parts of a curing agent, 10 to 15 parts of a microelement complexing agent, 6 to 10 parts of a hydrophobing agent, 30 to 50 parts of humic acid, and 50 to 60 parts of water. The method has the advantages that materials, such as the organic compound fertilizer, a microelement complexing agent, a hydrophobing agent and water, are cured and nucleated through a compounding technology by using the organic macromolecule nucleating agent and the curing agent and are prepared into solid granular fertilizer, the fertilizer cannot be dissolved and has certain hydrophobicity in washy and rainy conditions, so that fertilizer is promoted to slowly release effective components and prevent the problems of root ageing and root rot, and the effect of overcoming high-temperature and rainy obstacles can be achieved.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a preparation method of a solid fertilizer for preventing root system aging and root rot. Background technique [0002] With global warming, many southeastern regions of my country have more rainfall in summer and the frequency of rainfall increases, the duration increases, and the moisture content in the soil increases, prompting all the fertilizers applied to plants to dissolve in water, resulting in plant root solution The concentration is higher than the concentration inside the plant, which makes the plant unable to absorb water, nutrients and oxygen in the water, causing a large number of root systems to age and suffocate to death. Therefore, in order to avoid the problem of root aging and root rot caused by rainy days, we have invented a solid fertilizer to prevent root aging and root rot. Its solvent speed in water is relatively slow, and it will no...

Problems solved by technology

[0002] With global warming, many southeastern regions of my country have more rainfall in summer and the frequency of rainfall increases, the duration increases, and the moisture content in the soil increases, prompting all the fertilizers applied to plants to dissolve in water, resulting in plant root solution The concentration is higher than the concentration inside the plant, which makes the plant unable to absorb water, nutrients and oxygen in the water, causing a large number of root systems to age and suffocate.

Therefore, in order to avoid the problem of root aging and root rot caused by rainy days, we have invented a solid fertilizer to prevent root aging and root rot. Its solvent speed in water is relatively slow, and it will not promote the phenomenon of excessive root concentration.
