Embodiment 1

[0047] The high-efficiency biogas slurry organic suspension liquid fertilizer described in this embodiment contains the following components in parts by weight:

[0048]

[0049] The specific preparation method of the high-efficiency biogas slurry organic suspension liquid fertilizer comprises the following steps:

[0050] S1. According to the formula of compound fertilizer according to claim 1, filter the biogas slurry of the winery through a biogas slurry filter, separate slag, deodorize, effectively remove impurities in the biogas slurry, and obtain biogas slurry that can be drip-irrigated. Then the filtered biogas slurry and molasses are mixed evenly and placed as the S1 mother liquor, and 2 / 3 of the S1 mother liquor is added to the reactor.

[0051] S2. Slowly add boric acid, EDTA-Zn, EDTA-Mn to the S1 mother liquor, and stir for 20 minutes while adding;

[0052] S3. Add phosphoric acid and monoammonium phosphate to S2 mother liquor, stir while adding, the stirring ti...

Abstract

The invention discloses a high-efficiency biogas slurry organic suspension liquid fertilizer and a preparation method thereof. The high-efficiency biogas slurry organic suspension liquid fertilizer comprises, by weight, 21.0-42.0 parts of a biogas slurry, 6.0-9.0 parts of organic matters, 4.0-25.0 parts of a nitrogen fertilizer, 9.0-20.0 parts of a potassium fertilizer, 0.5-1.0 part of a boron fertilizer, 0.5-0.8 part of EDTA-Zn, 0.4-0.6 part of EDTA-Mn, 0.1-2.0 parts of a wetting dispersant, 0.1-2.0 parts of a thickener, 0.1-2.0 parts of an antifreeze agent and 0.1-1.0 part of a root promoter. The high-efficiency biogas slurry organic suspension liquid fertilizer is an organic-inorganic suspension liquid fertilizer, and the high-efficiency biogas slurry fertilizer is prepared by fermenting a substrate biogas slurry, so the problem of the pollution of discharge of the biogas slurry to the environment is effectively solved, the biogas slurry is transformed into valuables from wastes andis fully used, and the production cost of the liquid fertilizer is reduced. The fermented biogas slurry is used to prepare the liquid fertilizer, so the liquid fertilizer can be more rapidly dissolved in water than general products, and has the advantages of high total nutrient content, stable physical and chemical properties, and no crystallization, precipitation and stratification phenomena under high temperature, low temperature and normal temperature conditions.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a fertilizer containing biogas slurry, organic matter, macroelements and trace elements applied to crops, in particular to a high-efficiency biogas slurry organic suspension liquid fertilizer and a preparation method thereof. Background technique [0002] As a large agricultural country, my country has a large amount of biomass resources. With the development of centralized animal husbandry, the environmental problems caused by a large amount of livestock and poultry manure and a large amount of vegetable straw waste have become increasingly prominent. If it is not used rationally, it will not only pollute the ecological environment, but also cause a lot of waste of resources. Biogas slurry is widely used in agricultural production, and its application in production plays a positive role in improving soil fertility, regulating crop growth and improving t...
