Liquid biological organic fertilizer with high content of organic substances and preparation method

Abstract

The invention provides a liquid biological organic fertilizer with high content of organic substances and a preparation method. The fertilizer is characterized by comprising the following components by weight: 60% of a humic acid release inhibitor, 0.4% of a composite biological agent, 10% of fulvic acid potassium, 12% of soluble nitrogen-phosphorus-potassium raw materials, 9% of a chelating medium trace element agent, 8.47% of a soil conditioner, 0.93% of compound sodium nitrophenolate and 0.1% of naphthalene acetic acid; and the fertilizer is prepared by mixing, heating, chelating, concentrating, cooling, microorganism adding, filtering and residue removing. The invention has the following beneficial effects: plant nutrition is directly supplemented; the contents of absorbable organic substances for a root system in soil are rapidly supplemented; growth of the root system is rapidly promoted; absorption area of the root system is enlarged; the chelating medium trace element agent can not be fixed by the soil and exists in a free state in the soil, so the chelating medium trace element agent is easy to be captured and absorbed by the root system in the soil; physiological diseases and pests are prevented from occurrence; quality of an agricultural product is improved; root-rot disease and stem-rot disease are prevented from occurrence; occurrences of fusarium and verticillium wilts and bacterial wilt are reduced; meanwhile, the fertilizer is capable of resisting salinity and alkalinity, resisting continuous cropping diseases, and killing soil-borne diseases.

Description

technical field

[0001] The invention relates to a high-organic-matter liquid bio-organic fertilizer and a production method thereof, in particular to a liquid organic fertilizer containing various plant nutrient components, high in organic matter and biocomposite technology and a preparation method thereof. Background technique

[0002] The central government has issued 11 No. 1 documents in a row, clearly proposing policies to encourage farmers to increase the application of organic fertilizers, plant green manure, and return straw to the field. Extensive use of chemical fertilizers has caused serious soil pollution. The replacement of some chemical fertilizers with bio-organic fertilizers and bio-liquid organic fertilizers is expected to further increase the utilization rate of chemical fertilizers, improve the soil microenvironment, restore soil safety and health, and reduce pollution. Liquid bio-organic fertilizer and bio-organic fertilizer are organic fertilizers proces...
