Problems solved by technology

Heavy metals in nature are divided into biologically available state and biologically ineffective state. The effective state mainly refers to the ionic state that can be free in the environment and absorbed by the outside world. It is beneficial to the growth of crops, and the application of fertilizers made of microorganisms for the elimination of heavy metals is rarely promoted. In view of this, it is necessary to improve the traditional bio-organic fertilizers and their preparation processes

Abstract

The invention discloses a bio-organic fertilizer for absorbing heavy metals. The bio-organic fertilizer is characterized by comprising the following components in parts by weight: 33-45 parts of substrate, 12-18 parts of microbial flora and 19-27 parts of inorganic heavy metal absorbing material, wherein the substrate comprises the following components in parts by weight: 30-42 parts of animal waste, 26-38 parts of plant straw, 12-19 parts of rice hull and 11-20 parts of wheat bran. The microbial flora and the inorganic heavy metal absorbing material in the bio-organic fertilizer can effectively absorb heavy metal ions in soil, can mutually boost, are capable of promoting soil quality while removing heavy metals and are beneficial to growth of crops; fermenting raw materials are placed into a plug flow type fermentation cabin for fermenting, and meanwhile, a stirrer is adopted for continuously stirring, so that fermentation is more sufficient and uniform, quality and use ratio of bio-organic fertilizer can be promoted and the bio-organic fertilizer can be more fully decomposed and utilized to improve soil and reduce diseases.

Description

Technical field [0001] The invention relates to the technical field of biological organic fertilizers, in particular to a biological organic fertilizer for adsorbing heavy metals and a preparation process thereof. Background technique [0002] Bio-organic fertilizer refers to a type of fertilizer that is composed of specific functional microorganisms and organic materials that are mainly derived from animal and plant residues and undergoes harmless treatment and decomposing. The nutrient elements are complete, which can improve the soil, increase the resistance of plants to diseases and insects, and increase the yield and quality. Cultivated soil contains a small amount of heavy metals, mainly copper, cadmium, lead, chromium and zinc. These heavy metals mainly come from the soil itself and pollution caused by human industrial emissions. Industrial emissions of heavy metals are not only large in quantity, but also have a strong transfer ability and are easy to passive plants. abs...
