Fermented ecological environment-friendly organic fertilizer and preparation method thereof

Abstract

The invention discloses a fermented ecological environment-friendly organic fertilizer and a preparation method of the organic fertilizer, and belongs to the technical field of fertilizer preparation. The organic fertilizer comprises the following raw materials in parts by weight: 80-90 parts of pig manure, 15-20 parts of corn straw, 8-12 parts of attapulgite, 10-15 parts of charcoal, 7-10 parts of zeolite, 9-12 parts of bean dreg, 8-11 parts of biogas dreg, 3-4 parts of coptis chinensis dreg, 1-2 parts of radix bupleuri dreg, 4-5 parts of cortex pseudolaricis dreg, 2-3 parts of stellera chamaejasme dreg, 1-2 parts of clove dreg, 2-3 parts of rheum officinale dreg, 1-3 parts of ginseng dreg, 1.4-1.8 parts of fermentation agent and 0.3-0.5 parts of RW biological organic fertilizer function inoculant. The fermented ecological organic fertilizer makes full use of agricultural wastes, so that a yield of a crop is increased; an economic benefit is significant; the agricultural input cost is low; a utilization rate of the fertilizer is high; an effect of environmental protection is exerted; and the organic fertilizer is environment-friendly and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a fermented ecological and environment-friendly organic fertilizer and a preparation method thereof.
