Problems solved by technology

Except for a small part of the straw produced in agricultural production, which is effectively used by returning to the field, ammoniation, silage, fermentation and used as a culture medium for edible fungi, most of it is incinerated, which not only causes environmental pollution but also leads to a waste of resources.

Abstract

The invention relates to a charcoal-based organic fertilizer and a preparation method thereof. The charcoal-based organic fertilizer comprises charcoal, fertilizer and adhesive. The charcoal-based organic fertilizer is characterized in that the mass ratio of charcoal to fertilizer to adhesive is at 9:(18-36):(1-8). According to the invention, the charcoal is prepared from agricultural wastes (oneor more of maize straws, wheat straws, soybean straws and cotton straws), so that resource waste and damage to environment caused by straw burning can be avoided and sustainable application of strawscan be guaranteed. The charcoal-based organic fertilizer is prepared by mixing charcoal, fertilizer and adhesive at a ratio and pelletizing. The preparation process is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of biochar-based fertilizers, in particular to a biochar-based organic fertilizer and a preparation method thereof. Background technique [0002] In agricultural production, traditional chemical fertilizers have many disadvantages, not only polluting the environment, but also having a low utilization rate. my country is a large agricultural country with abundant plant biomass resources. The total annual production of biomass resources such as crop straws has exceeded 1 billion tons. Except for a small part of the straw produced in agricultural production, which is effectively used by returning to the field, ammoniation, silage, fermentation and used as a culture medium for edible fungi, most of it is incinerated, which not only causes environmental pollution but also leads to a waste of resources. . [0003] Biochar-based fertilizers have a high degree of stability and strong nutrient adsorption and retent...
