Abstract

The invention discloses kelp residue seed coating pesticide fertilizer as well as a preparation method and a coating method thereof. The kelp residue seed coating pesticide fertilizer is prepared fromthe following raw materials in parts by weight: 65 to 70 parts of kelp residue, 20 to 25 parts of modified attapulgite, 0.5 to 0.8 part of compound fertilizer powder, 3 to 5 parts of a compound antibiological inoculant, 0.13 to 0.29 part of pesticide, 3 to 8 parts of agricultural neutral sodium polyacrylate, 0.7 to 0.9 part of ammonium molybdate and 0.3 to 0.6 part of ferrous sulfate. According to the kelp residue seed coating pesticide fertilizer disclosed by the invention, through improvement and reasonable proportioning on production raw materials, components of antibacterial and insect-proof organic and inorganic nutrients, growth promoting factors and the like can be generated after the kelp residue seed coating pesticide fertilizer is applied to seed coating of corn, rice or peanuts; meanwhile, the kelp residue seed coating pesticide fertilizer has the advantages that the cost is low, the validity period of nutrients is long, the alkalinity of alkaline soil can be regulated andthe like, and the germination rate and the disease resistance of seeds can be increased.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to a kelp dregs seed-coated medicinal fertilizer and a preparation and coating method thereof. Background technique [0002] Seed coating technology is a widely used seed treatment technology developed on the basis of traditional seed soaking and seed dressing. Seed coating fertilizer is developed on the basis of traditional pesticide-type seed coating agent. It is mainly a kind of seed that is coated on the surface of the seed with an appropriate concentration after mixing fertilizers, pesticides, growth regulators and fungicides evenly. Coating agent. It not only has the insecticidal and bactericidal effects of traditional pesticide-type seed coating agents, but also provides nutritional support for the early growth of crops. However, the pesticides attached to the surface of the seeds treated with the coating agent will erode the endosperm and germ of t...
