Meat waste material fermented fertilizer and preparation method thereof

Abstract

The invention discloses a meat waste material fermented fertilizer and a preparation method thereof. The meat waste material fermented fertilizer is prepared from, by weight, 4 wt%-6 wt% of HCl solution, zinc oxide powder, fish heads, fish viscera, chicken viscera, seafood waste materials, biogas digester silt, a compound enzyme preparation, chicken manure, ferrous sulfate, urea, rice straw powder, potassium permanganate, boric acid, cellulose homogenate and water. A lot of meat waste materials exist in life and are difficult to treat and prone to breed bacteria, pests, viruses and the like, and environmental hygiene is seriously affected; the biogas digester silt which is rich in various fermentation bacteria is utilized for serving as composting powder of meat fermentation materials and matched with the enzyme preparation, waste compositions can be decomposed into humic acids and a small amount of amino acids to be used for adsorbing inorganic elements, the function of promoting inorganic mineral absorption is achieved, soil humus is increased, and the soil texture is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a meat waste fermented fertilizer and a preparation method thereof. Background technique [0002] The usual fertilizer coating has the initial sulfur-coated urea technology, and then the Japanese-style thermosetting resin coating technology. The basis of these resin materials is mainly polyolefin, which is formed by grafting and copolymerizing with some organic polymers. The high polymer is mixed with a certain amount of inorganic mineral stone powder to make a coating material. The inorganic mineral stone powder used includes silicon, sulfur, gypsum, phosphate, zeolite powder, diatomaceous earth, bentonite, etc. The United States first successfully developed sulfur Coated urea, the film layer is composed of sulfur-coated layer, sealing layer and powder coating layer, which occupies an important position in today's sulfur-coated slow-release powder; [0003] But ...

AI Technical Summary

Problems solved by technology

[0003] But the disadvantages are obvious: although the stone powder coating fertilizer can improve the soil mineral quality, it needs the addition of chemical organic matter to bond, mainly the addition of resin, but the preparation of slow-release fertilizer, the resin binder used in the coating varies. The proportion, addition amount and selection of types are problems. Improper control will affect the timely supply of fertilizers. Slightly improper control will cause the coating of stone powder to be easily cracked by moisture, sandy soil, and reduce the relative proportion of humus in the soil. Water and soil erosion is very unfavorable for long-term planning; on the other hand, the coating material of stone powder is used, and the stone powder itself has a certain thickness, which seriously affects the real effective content of the coated fertilizer. If the content of added nutrients is increased, the fertilizer will inevitably increase. Particle size, very unfavorable for dissolution and fertilizer balance issues
