Chicken manure organic fertilizer for microbial fermentation

Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to a chicken manure organic fertilizer for microbial fermentation, which comprises the following components in percentage by weight: 45-70% of chicken manure, 5-20% of bran powder, 15-35% of straw powder, 0.1-2% of EM (effective microorganism) stock solution, 0.1-2% of corn flour and 0.5-4% of bran coat. The chicken manure organic fertilizer has the advantages of wide application range, and can use dry chicken manure, fresh chicken manure and southern high-water-content chicken manure as the raw material, so the method is free from raw material restriction; the fermentation time is generally 5-10 days, so the fermentation period is short, and the chicken manure organic fertilizer can implement large-scale production; the chicken manure organic fertilizer does not need screening, and the yield is high (up to more than 90%); and since the consumption is low in practical application, the consumption of the chicken manure organic fertilizer can be greatly lowered (about less than half of the commercially available organic fertilizer at present) to achieve the same fertilizer application effect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a chicken manure organic fertilizer fermented by microorganisms. 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 needed 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 repeated application of chemical fertilizers, various excellent properties of the soil have been seriously degraded: (1) pH changes and salinity increases; (2) The soil is severely compacted, leading to a serious degradation of water retention and air permeability; (3) The beneficial biological flora in the soil is reduced, resulting in poor plant growth, greatly increasing the probability of...

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 for farming equipment, and it also affects the sowing of crops, and cannot be widely promoted; (5) It cannot completely solve the problem of soil compaction and environmental pollution caused by chicken manure and straw

For example, Chinese patent applications with application numbers 201210440548.9, 201110326856.4, 201210481607.7 and 201410098307.X all disclose a kind of chicken manure organic fertilizer. Dried chicken manure is fermented as the main raw material, which cannot ferment the chicken manure with high moisture content unique to the hot and humid weather in the south. Therefore, the methods disclosed in these patent applications are limited by the raw materials; (2) Fermentation time Generally in 20-40 days, the fermentation period is long, which affects the processing capacity and cannot be produced on a large scale; (3) often needs to be screened, the output is small, and the yield is low; (4) in practical applications, better results should be achieved , need to use a lot of
