Biochar organic fertilizer and preparation method thereof

Abstract

The biochar organic fertilizer is prepared from the following components in parts by weight: 100 parts of biochar, 110 to 120 parts of pig manure, 15 to 19 parts of domestic sludge, 10 to 15 parts of fermentation inoculant and 7 to 10 parts of brown sugar. Wherein the fermentation inoculant is formed by compounding photosynthetic bacteria, rhizobium and saccharomycetes according to the compounding weight ratio of 2: 1: 1. The preparation method of the organic fertilizer sequentially comprises the following steps that the biochar, the pig manure, the domestic sludge, the fermentation inoculant and the brown sugar are blended and fermented, the fermentation temperature is 60-65 DEG C, the fermentation time is 10-15 days, stirring is conducted for 5-10 times during fermentation, the organic fertilizer is prepared through granulation and screening, and the organic fertilizer can reduce nitrogen emission and nitrogen loss during fermentation of the pig manure.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, and in particular relates to a biochar organic fertilizer and a preparation method thereof. Background technique [0002] Biochar is a kind of charcoal used as a soil conditioner, which can help plants grow, and can be used for agricultural purposes and carbon collection and storage, which is different from traditional charcoal which is generally used for fuel. [0003] Like ordinary charcoal, biochar is the product of biomass energy raw materials after pyrolysis, and its main component is carbon molecules. Because of the study of the black soil of the Amazon, scientists became interested in biochar. In Japan, the use of biochar in agriculture also has a long history. [0004] The decay of plants naturally creates a large amount of carbon in the soil. But these carbons are relatively unstable and are greatly affected by climate. Soils release carbon dioxide when they en...
