Abstract

The invention provides an organic compound fertilizer and a preparation method thereof, and relates to the technical field of organic compound fertilizers. The organic compound fertilizer comprises the following raw materials in parts by weight: 40-50 parts of urban living sludge, 4-5 parts of zeolite, 15-20 parts of straws, 10-16 parts of animal waste, 20-30 parts of fly ash, 7-12 parts of distiller's grains, 1-1.5 parts of an FA microbial expanded bacteria group, 6-8 parts of urea, 2-3 parts of calcium hydrogen phosphate, 3-4 parts of ammonium nitrate, 1-2 parts of potassium sulfate and 0.5-1 part of sodium borate. The preparation method comprises raw material pretreatment, primary fermentation, repeated fermentation, post-treatment and packaging. The organic compound fertilizer is capable of significantly improving the crop yield and quality, is balanced in nutrient distribution ratio, and is capable of improving the soil structure, improving the utilization rate of N and effectively improving the soil water retention and fertilizer retention, and is environmentally friendly; the preparation method is simple, low in investment and cost, and convenient to promote and utilize.

Description

technical field [0001] The invention relates to the technical field of organic compound fertilizers, in particular to an organic compound fertilizer and a preparation method thereof. Background technique [0002] Organic compound fertilizer mainly refers to the fertilizer for agricultural production that mixes organic fertilizer and inorganic fertilizer according to a certain ratio, and contains a variety of effective auxiliary microorganisms and high-energy compounds. Among them, organic fertilizer is also called farmyard manure in a broad sense. It mainly refers to various animal and plant residues and metabolites. The emerging organic fertilizer also includes sludge and some food or paper industry waste products. [0003] In the treatment of sewage, various separation methods are used to remove dissolved, suspended or colloidal solid substances, and the resulting sediment becomes sludge. The treatment of sludge is a burden for a city, and the demand for funds and sites is...
