Description

1. Technical field: [0001] The invention relates to an agricultural fertilizer, in particular to a nanoscale slow-release and controlled-release medicinal fertilizer and a preparation method thereof. 2. Background technology: [0002] my country is rich in mineral resources, but the active ingredients of mineral products are rarely used, and the extraction and separation applications are even less. Similar domestic similar technologies have complex process design, low technological content, and high prices for controlled-release products. The utilization rate of effective nutrients is low, the nutrient in the product is single, the stress resistance function is poor, and it does not contain bactericidal ingredients, the plant absorption rate is low, and the nutrient leaching and precipitation are many, resulting in excessive harmful residues in the soil, which seriously affects the export-oriented agricultural economy. development of. 3. Contents of the invention: [000...
