Preparation method of saving ecological lobster-rice mixed culture compound fertilizer

Abstract

The invention discloses a preparation method of a saving ecological lobster-rice mixed culture compound fertilizer, wherein the preparation method comprises the following steps: stirring fruit shell charcoal, weathered coal, quartz sand coal, pottery clay and water, filtering, drying, sending into a phosphoric acid solution, soaking, filtering, carbonizing a filter residue, then adding a sodium hydroxide solution, stirring, filtering, washing, and drying to obtain a prefabricated material; and mixing ammonium nitrate, diammonium hydrogen phosphate, a calcium-magnesium phosphate fertilizer, potassium nitrate, tea seed meal, biogas residue, fermented pig manure, meat and bone meal, magnesium humate, zinc humate and calcium carbonate evenly, adding the prefabricated material, sweet potato starch, locust bean gum and a film-forming stabilizer, stirring, granulating and drying to obtain the saving ecological lobster-rice mixed culture compound fertilizer. The film-forming stabilizer is prepared by the following processes: mixing ethylene glycol, sorbitol and polyethylene glycol, adding terephthalic acid, carrying out a reaction, heating up, adding branched polyethylene wax and liquid paraffin, mixing evenly, then adding lauryl sodium sulfate evenly, and adding boiling water to obtain the film-forming stabilizer under a stirring condition.

Description

technical field [0001] The invention relates to the technical field of ecological planting, in particular to a preparation method of eco-saving crayfish and rice polyculture compound fertilizer. Background technique [0002] Now rice planting and crayfish farming are both separate, that is, when raising crayfish, a place is enclosed to only raise crayfish, while rice planting is only rice planting, and the paddy field is idle after the rice is harvested. Such a traditional farming method It is a waste of land and not ecological. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a preparation method for saving ecological crayfish and rice polyculture compound fertilizer. Excellent release performance, can significantly promote the healthy growth of rice, thereby increasing yield, improving quality, increasing economic benefits, while reducing fertilizer input, reducing the risk of enviro...
