Embodiment Construction

[0020] Below in conjunction with 6 examples the present invention is described in detail, but the present invention is not limited to the given embodiment.

[0021]

[0022] In the embodiment, the solid EM bokashi and chicken manure are mixed according to the above weight ratio, piled up, covered with a plastic film, and fermented under airtight conditions, wherein the plastic film is turned over once every other week, and during the turning process Spray 1% liquid EM in the middle, then cover the film to continue fermentation, after 21-25 days of fermentation, dry it.

[0023] Measured by standard methods, the pH range of the bio-organic fertilizer made in each embodiment is 7-7.5; the C / N value range is 12-15; the NO 3 - -N / NH 4 + -N value≥3.5; total nitrogen≥1.6%; total phosphorus≥1.4%; total potassium≥1.2%; seed germination index (GI)≥95%; Equal to 35%, heavy metals Cu and Zn do not exceed the standard.

[0024] During the composting and fermentation of chicken ma...

Abstract

The invention relates to a biological organic fertilizer. An agricultural waste (chicken manure) is converted into the biological organic fertilizer which is nuisanceless, can be applied to the organic cultivation of paddies, and belongs to the technical field of special biological fertilizers for the paddies. The biological organic fertilizer is formed by uniformly mixing and composting the following raw materials in part by weight by means of microbial fermentation: 5-8 parts of EM (effective microorganism) solid Bo Kathy, 88-92 parts of the chicken manure (with a moisture content of 50%-60%), and 3-4 parts of 1% EM stock solution. The biological organic fertilizer has the advantages that the fermentation technique is simple, the fermentation time is short, the composted biological organic fertilizer has complete nutrition and high fertilizer efficiency, is nuisanceless and can replace the application of a chemical fertilizer and a farm insecticide, the capability of the resistance to the diseases and the insect pests of the paddies can be improved, and the quality of paddy rice is improved; and synchronously, the biological organic fertilizer further has the characteristics that the agricultural surface source pollution is controlled in terms of a source, the ecological environment of a paddy field is protected, and the sustainable development of the production of the paddies is promoted. The biological organic fertilizer has an obvious application effect in the production of organic paddies and has wide market foreground and better economic benefit and environmental benefit.

Description

[0001] technical field [0002] The invention belongs to the technical field of special biological fertilizers for rice, and uses biological technology to stack and ferment agricultural waste chicken manure to generate pollution-free biological organic fertilizers, so as to replace chemical fertilizers, improve soil, improve the ability of rice to resist diseases and insect pests, and improve rice quality. Controlling agricultural non-point source pollution from the source and protecting the ecological environment of rice fields. Background technique [0003] Bio-organic fertilizer is a new, efficient and safe microbial-organic compound fertilizer formed by compounding a variety of beneficial microbial flora and organic fertilizer. This is a new type of fertilizer formed on the basis of the development of microbial technology and the commercialization of organic fertilizers in recent years. , it is the inheritance and development of traditional organic fertilizer. Bio-organ...
