Chicken manure fermented biological organic fertilizer and preparation method thereof

Abstract

The invention discloses chicken manure fermented biological organic fertilizer. The chicken manure fermented biological organic fertilizer comprises the following components in parts by weight: 150 to200 parts of chicken manure, 20 to 27 parts of shrimp shells, 25 to 32 parts of crab shells, 80 to 120 parts of fermented base materials, 30 to 55 parts of wormwood ash, 18 to 29 parts of composite fungicide, 40 to 55 parts of gleditsia sinensis branches and leaves, and 12 to 18 parts of deodorizing fungicide. The invention also provides a preparation method of the chicken manure fermented organic fertilizer. The preparation method includes the following steps: pretreating materials, performing anaerobic fermentation, performing aerobic fermentation, mixing, drying, crushing, and preparing into a finished product. By the chicken manure fermented biological organic fertilizer, not only can the soil structure and the soil permeability be improved, but also heavy metal ions in the soil can be degraded, and the insect harm resistance of crops can also be improved; the odor and harmful bacteria in the chicken manure are removed by virtue of microorganism bacteria in the preparation process; the preparation method can shorten the fermentation period and improve the fermentation efficiency. The invention also provides an organic fertilizer fermentation apparatus, which can switch the material fermentation between an anaerobic environment and an aerobic environment at any time.

Description

Technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a chicken manure fermentation biological organic fertilizer and a preparation method thereof. Background technique [0002] During the growth of crops, a large amount of nitrogen, phosphorus, potassium and various trace elements are needed. In order to ensure the various nutrients required for crop growth, people often apply various inorganic chemical fertilizers to the soil. [0003] Although the application of chemical fertilizers can meet the needs of crop growth, due to partial application, single application and reapplication of chemical fertilizers, various excellent soil properties have been seriously degraded: pH changes and salinity increases; soils appear serious Hardening leads to serious degradation of water retention and air permeability; the reduction of beneficial biological flora in the soil leads to poor plant growth, greatly increases the probability of pl...

Problems solved by technology

Although these methods and measures can temporarily solve the contradiction between planting, breeding and the environment, there are also obvious deficiencies: (1) Reducing the use of chemical fertilizers will make crops lack the necessary nutrients for growth and affect yield; (2) The use of farmyard manure will cause germs and parasites to infect crops again, endangering human health; (3) Drying and deodorizing chicken manure to prepare organic fertilizers consumes a lot of energy and costs, which limits the production capacity of enterprises; (4) Straw Land return has high requirements on farming equipment, and it also affects the sowing of crops, so it cannot be popularized in a large area; (5) It cannot completely solve the problem of soil compaction and environmental pollution caused by chicken manure and straw; It is easy to attract some insects during fertilization. These insects will not only absorb the organic fertilizer in the soil but also damage the crops
