Cyanobacteria organic fertilizer and preparation process thereof

Abstract

The invention discloses a cyanobacteria organic fertilizer and a preparation process thereof. The cyanobacteria organic fertilizer comprises 30-40 parts of cyanobacteria powder, 20-30 parts of bean meal residues, 15-25 parts of straw powder, 10-15 parts of coal residue, 1-3 parts of compound microbial flora, 0.5-2 parts of potassium dihydrogen phosphate, 0.2-1 part of ammonium chloride and 0.2-0.5part of magnesium sulfate. The preparation method comprises the following steps: by taking cyanobacteria powder as a main raw material, adding bean meal residues, straw powder, coal residue, compoundmicrobial flora, potassium dihydrogen phosphate, ammonium chloride and magnesium sulfate, uniformly mixing and stirring, carrying out aerobic composting in a constant-temperature constant-humidity incubator through microbial fermentation, and finally drying the fermented material to prepare granules so as to obtain the cyanobacteria organic fertilizer finished product. According to the invention,an organic fertilizer is obtained through microbial fermentation by using cyanobacteria eutrophicated in water as a main raw material, is rich in nutrition elements and is an organic fertilizer withgood comprehensive energy efficiency.

Description

technical field [0001] The invention relates to the field of biochemical technology, in particular to a cyanobacteria organic fertilizer and a preparation process thereof. Background technique [0002] In recent years, the degree of eutrophication in my country's water bodies has become increasingly serious. Cyanobacteria exist in nutrient-rich water bodies, often multiply in large numbers in summer, and form a layer of blue-green and fishy-smelling floating foam on the water surface, which is called "water bloom". Large-scale algal blooms are known as "green tides". At present, there are many researches on cyanobacteria treatment at home and abroad, and salvage is the fastest way to solve the crisis of cyanobacteria, but the research on the treatment and disposal of salvaged cyanobacteria is relatively lagging behind. Domestic and foreign studies on the utilization of cyanobacteria mainly include the preparation of amino acids for feed, the extraction of phycocyanin, algal ...
