Coated fertilizer for wheat seeds

Abstract

The invention relates to the technical field of fertilizers, and in particular relates to a coated fertilizer for wheat seeds. The coated fertilizer comprises the following raw materials in parts by weight: 47-58 parts of urea, 38-49 parts of phosphorus pentoxide, 26-37 parts of polypeptide chelated potassium, 5-10 parts of a film forming agent, 3-8 parts of sepiolite powder, 0.2-0.45 part of naphthaleneacetic acid, 0.15-0.25 part of uniconazole, 1.5-4.6 parts of ferric sulfate, 2.5-3 parts of magnesium sulfate, 1-2 parts of copper sulfate, 0.1-0.7 part of reactive brilliant red, and 0.3-0.6 part of bis(2-ethylhexyl) phthalate. The coated fertilizer disclosed by the invention can effectively enhance a survival rate of the wheat seeds.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat seed coating fertilizer. Background technique [0002] Although the current slow / controlled release fertilizers have achieved certain effects in improving the nutrient utilization rate of ordinary fertilizers and reducing the environmental pollution caused by nutrient leaching of ordinary fertilizers, there are still the following major deficiencies: (1) the existing slow / controlled release fertilizers Fertilizers only modify the structure of ordinary fertilizers or coat ordinary fertilizers without changing the carrier and application method of ordinary fertilizers. Fertilizers are still applied on the soil surface where crops grow or on cement-containing soil, and the fertilizer is far away from the root system of crops. , easy to be leached by rainwater, resulting in ineffective improvement of fertilizer nutrient utilization efficiency. (2) The coating materials o...

[0002] Although the current slow / controlled release fertilizers have achieved certain effects in improving the nutrient utilization rate of ordinary fertilizers and reducing the environmental pollution caused by nutrient leaching of ordinary fertilizers, there are still the following major deficiencies: (1) the existing slow / controlled release fertilizers Fertilizers only modify the structure of ordinary fertilizers or coat ordinary fertilizers without changing the carrier and application method of ordinary fertilizers. Fertilizers are still applied on the soil surface where crops grow or on cement-containing soil, and the fertilizer is far away from the root system of crops. , easy to be leached by rainwater, resulting in ineffective improvement of fertilizer nutrient utilization

(2) The coating materials of the existing slow / controlled release fertilizers are expensive, the equipment investment is large, the production process is relatively complicated, the coating process requires long-term high-temperature treatment, and the energy consumption is large, resulting in high production costs of the slow / controlled release fertilizers. 5 to 14 times that of ordinary fertilizers before coating

(3) Existing slow / controlled release fertilizers use petroleum solvents such as toluene, xylene, and petroleum ether to dissolve coating materials, which are highly toxic and harmful to the health of production and application personnel; some use trichloroethylene, tetrachloroethylene, etc. As a solvent, it will destroy the ozone layer and cause air pollution
