Abstract

The invention provides a preparation method of a slowly-released nanoparticle compound fertilizer. The method is characterized in that the surface of medical stone is grinded with abrasive paper, so that the roughness of the surface of the medical stone can be improved, and a load point is provided to nanoparticle ions; medical stone is used as a carrier on which nanoparticles are loaded, so thatthe nanoparticle dispersing effect can be effectively improved, the agglomerating is avoided, and the utilization rate of the nanoparticles can be increased; first mixed materials are sterilized underhigh temperature, so that the carrying harmful bacteria can be effectively decreased, and as a result, the prevalence of plants can be decreased; in addition, the quick low-temperature cooling is performed, so that the production of the harmful bacteria in the cooling process can be reduced; isatis root, folium isatidis, Pudilan (dandelion, bunge corydalis herb and isatis root), astragalus membranaceus and bunge corydalis herb are added and capable of effectively exterminating harmful bacteria in the soil; and meanwhile, the abovementioned traditional Chinese medicines are extracted and prepared into mixture, so that the synergistic effect of the traditional Chinese medicines can be ensured, and that the traditional Chinese medicines are dispersed during being stirred, resulting in reduction of bacteria exterminating effect, can be avoided.

Description

technical field [0001] The invention relates to a composite nanopowder, in particular to a preparation method of slow-release nanoparticle composite fertilizer. Background technique [0002] With the continuous development of agriculture, fertilizer has become an indispensable substance in modern agriculture. Nanomaterials are a new type of material, which can effectively store nutrients in the root system of plants to absorb nutrients and promote plant growth. Moreover, it can effectively improve the properties of the soil, and can effectively prevent the phenomenon of soil defertilization and several lumps. Therefore, nanomaterials are widely used in fertilizers. However, due to the small particle size of nanomaterials, they are prone to agglomeration, resulting in its Decreased or lost function. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be...
