Abstract
The invention relates to the field of compound fertilizer, and in particular to an antibiotic yield-increasing slow-release compound fertilizer containing nano silver coating. The fertilizer is prepared from the following raw materials by weight:10-15 parts of diatomite of 1250-2000 mesh, 15-28 parts of ammonium hydrogen carbonate, 2-4 parts of expired pine pollen, of 8-10 parts of vinegar residue, 6-8 parts of calcium phosphate primary, 5-6 parts of molasses fermentation liquid, 1-2 parts of hexaammonium molybdate, 8-10 parts of filter mud, 5-8 parts of BFA, 4-6 parts of borax, 0.01-0.02 part of sodium selenite, 6-8 parts of a guava leaf water extract, 10-12 parts of Melilotus suavcolen, 6-8 parts of river locust leaf, 15-18 parts of sodium alginate, 3-5 parts of glycerol, 0.001-0.002 part of nanometer silver, 1-3 parts of sodium dodecyl benzene sulfonate (ABS) and 4-5 parts of an auxiliary. The compound fertilizer provided by the invention has extensive raw material sources, comprehensive and rich nutrients and a variety of natural organic fertilizers; diatomite, glycerol and nano silver modified sodium alginate slow-release coating agent are utilized in the production process to form a double coating; the fertilizer has lasting and stable fertilizer releasee, antimicrobial and antiseptic effects, does not destroy the soil environment, and can effectively increase crop yield and improve planting benefit.
Description
technical field [0001] The invention relates to the field of compound fertilizers, in particular to an antibacterial and production-increasing slow-release compound fertilizer containing nano-silver coating. Background technique [0002] In modern agricultural production, compound fertilizer can be seen everywhere. It has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, and convenient storage and application. It plays an important role in promoting high and stable crop yields. Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the focus of research on the development of my country's chemical fertilizer industry. Its slow-release principle is to coat a thin layer of hydrophobic substances on the surface of fertilizer particles, so that the internal nutrients are slowly released to the In the soil, nutrients are continuously supplied to crops, which effectively improves the utili...
