Problems solved by technology

Attapulgite is used as a slow-release agent for fertilizers. If the amount is too small, the slow-release effect may not be obvious; but too much may cause the nutrient release of the fertilizer to be too slow, affecting the growth and development of crops in the early stage

Abstract

The invention discloses an attapulgite mineral powder slow-release fertilizer, relates to a fertilizer taking mineral substances as main raw materials and belongs to the field of fertilizer preparation. The attapulgite mineral powder slow-release fertilizer is characterized by being prepared from the following raw materials by weight percent: 60% of attapulgite mineral powder, 10% of livestock manure, 10% of weathered coal, 15% of microelement and 5% of fermentation strain. The attapulgite mineral powder slow-release fertilizer has the beneficial effects that the attapulgite mineral powder is applied to soil fertilizer so that heavy metals in soil can be adsorbed, the ventilation of the soil is improved, the soil hardening and virosis are reduced and eliminated, the use amount of chemical fertilizer and pesticide is reduced, the production cost is reduced, the pollution is reduced, the ecological environment of the soil is optimized, the microecological balance of the soil is achieved, the crop is matured in advance, the quality of the crop is improved, the toxic and harmful substances residual in the crop are reduced and eliminated, and the heavy-metal residue of the crop achieves the green and environment-friendly requirement; and the attapulgite mineral powder forms a micromatrix and are combined with nutrients to form an unique controlled release technique.

Description

technical field [0001] The invention relates to a fertilizer with mineral as the main raw material, belonging to the field of fertilizer preparation, in particular to an attapulgite slow-release fertilizer. Background technique [0002] Slow-release fertilizers refer to new fertilizers that can slow down or control the release rate of nutrients; slow-release fertilizers include two types: slow-release fertilizers and controlled-release fertilizers. "Slow release" means that the nutrient release rate of chemical substances is much lower than that of instant fertilizers; "controlled release" means that various regulatory mechanisms are used to release nutrients according to the set release mode (release rate and release time) and the law of crop absorption of nutrients consistent. Therefore, organic nitrogen compound (urea-formaldehyde) fertilizers that can be decomposed under biological or chemical action are usually called slow-release fertilizers, while coated fertilizers...
