Embodiment 1～4

[0018] The bio-organic fertilizer is prepared by mixed fermentation of pig manure, corn stalks, urea and functional microbial agents as follows:

[0019] (1) Pig manure, corn stalks and urea are used as raw materials to ferment bio-organic fertilizers. The total mass of fermented materials is 300kg. The ingredients are prepared according to the wet weight ratio of pig manure: corn stalks: urea 5: 1: 0.02. The properties of the three materials are shown in Table 1. The C / N ratio of the mixed material is 30.4, and the moisture content is 64.7%.

Abstract

Plant-growth-promoting bio-organic fertilizer is prepared by inoculating 0.5-2% (w/w) of composite fermentation microbial agent to livestock-poultry manure and auxiliary material, fermenting, inoculating 2-5% (w/w) of plant-growth-promoting microbial agent and fermenting. A preparation method includes steps: (1), preparing a fermenting material; (2), performing high-temperature aerobic fermentation; (3), preparing the plant-growth-promoting microbial agent; (4), after-composting organic fertilizer. The plant-growth-promoting bio-organic fertilizer and the preparation method have the advantages that rapid proliferation of plant-growth-promoting functional microorganisms is realized in the process of fermenting of two times, and effective biological viable bacteria count of the organic fertilizer reaches 5x108CFU/g; composting degree is high, the organic fertilizer can generate various plant hormones including 3-indoleacetic acid, cytokinin, gibberellins and ethylene after being applied in soil, can promote plant growth and can increase yield of crops and incoming of farmers; the bio-organic fertilizer prepared by the method is low in cost, environment-friendly and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizers, and in particular relates to a plant growth-promoting bio-organic fertilizer produced by fermenting livestock and poultry manure and a method thereof. Background technique [0002] With the rapid development of large-scale and intensive livestock and poultry breeding industry, livestock and poultry manure, as the main source of agricultural non-point source pollution, has become a prominent problem of environmental pollution. In contrast, livestock and poultry farming pollutants are rich in organic matter, nitrogen, phosphorus, potassium and other nutrients and trace elements, and have great potential for resource utilization. The use of aerobic fermentation to produce organic fertilizer is currently the most important means for the treatment and resource utilization of livestock and poultry manure. However, the traditional process of producing organic fertilizer from livestock a...
