Abstract

The invention discloses a method for preparing a high-utilization wheat special fertilizer. The method for preparing the high-utilization wheat special fertilizercomprises the following steps of adding iron(III)-ureacomplex, diatomaceous earth, coconut shell charcoal, medical stone powder, expanded perlite and peanut shell powder into water, heating and stirring to obtain a premix, mixing the waste of a fermentation slaughterhouse, rice, potato flour, fish bone meal and fermented silkworm excrement, adding water, grinding, adding the premix, ammonium bicarbonate, precipitated phosphate fertilizer and potassium nitrate, evenly stirring, drying and granulating, spraying an anti-caking coating agent to the surface, and drying to obtain the high-utilization wheat special fertilizer. The anti-caking coating agent is prepared by the following process of mixing mannitol, tween, sodium lauryl sulfate and water, heating and stirring, adding tetrachlorosilane and tetraethyl silicate, stirring, adding ethyl cellulose,epoxidized soybean oil and acetone, evenly mixing, washing, freeze-drying in vacuum to obtain the anti-caking coating agent.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing high-utilization wheat special fertilizer. Background technique [0002] my country is a large wheat planting country, and the use of chemical fertilizers is extremely high. The fertilizer utilization rate in my country has been at a low level for a long time, which has severely affected farmers' enthusiasm for planting wheat and caused serious environmental pollution, which is not conducive to the construction of sustainable development in my country High-yield modern industry technology system. Therefore, it is of great practical significance to provide a new type of wheat fertilizer, control the loss of nutrients in farmland, improve fertilizer utilization, and reduce wheat disease rate. Summary of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing a high utili...
