Abstract

The invention discloses a slow release bulk blend fertilizer and a preparation method thereof. The slow release bulk blend fertilizer comprises a composition A and a composition B, wherein the composition A contains urea, cellulose, tea seed cake, carbon black, polypropylene glycol, diammonium phosphate, triple superphosphate, potassium sulphate, potassium chloride, modified plant ash, sweet potato leaves, mushroom dreg, distillers' grains, water soluble phenol-formaldehyde resin, zinc sulfate, ferrous sulfate and nitrogen-fixing bacteria; and the composition B contains pond sludge, acrylic emulsion, ethyl acetate, ammonium acrylate, amino acid, calcium powder, alpha-pimacol, glucolactone, ammonium molybdate, micronutrients fertilizer, nano-montmorillonite and silicate potash fertilizer. Plant straws are incinerated and modified by using epoxidized soybean oil and calcium lignosulphonate, thus an absorption structure is increased, blocking is prevented and dispersity is increased; and resistance to lodging, diseases and drought of plants is effectively provided, the plant absorption rate is high, the damage to soil is correspondingly reduced, waste materials are recycled, and the fertility of a fertilizer is effectively increased.

Description

technical field [0001] The invention relates to the field of organic fertilizer manufacturing, in particular to a slow-release blended fertilizer and a preparation method thereof. Background technique [0002] my country is a big producer of chemical fertilizers and a big consumer of chemical fertilizers. Most of the nutrients in organic fertilizers are absorbed by the soil, and the absorption rate of plants is very low, resulting in soil pollution by nitrates and nitrites, soil compaction, and generation of harmful gases. Therefore, the pollution of the soil by chemical fertilizers and pesticides is another crisis. [0003] At present, people generally use inorganic fertilizers to fertilize crops, but long-term use of inorganic fertilizers will cause soil compaction, short fertility time, poor absorption rate of crops, seriously affect the survival of crops, and cause crop production reduction. Contents of the invention [0004] The object of the present invention is to p...
