Abstract

The invention discloses a cyanobacteria organic fertilizer comprising the following raw materials in parts by weight: 40-70 parts of cyanobacteria powder, 10-25 parts of total nitrogen, 5-20 parts of phosphorus pentoxide and 5-15 parts of potassium oxide. According to the cyanobacteria organic fertilizer disclosed by the invention, algae mud is dried by using a drying tower so as to greatly improve the production efficiency; a conventional air-drying method at least needs three days for drying one ton of the algae mud, and is also controlled by the weather conditions; a method disclosed by the invention only needs 10 minutes for drying one ton of the algae mud so as to fully meet the requirements of large-scale production. The cyanobacteria organic fertilizer disclosed by the invention is used for preparing a bio-organic fertilizer by adopting water-blooming cyanobacteria as a main raw material, is simple in process, also is used for performing wall-breaking and detoxication treatment on cyanobacteria, is safe and efficient in fertilizer application, can be used for turning waste into wealth, also can be used for solving the problem of environmental pollution caused by water-blooming cyanobacteria, has significant economic benefits, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to an organic fertilizer made from water bloom blue-green algae as a raw material and a preparation method thereof. Background technique [0002] Cyanobacteria are the earliest photosynthetic and oxygen-evolving organisms, and they have played a huge role in changing the earth's surface from an oxygen-free atmospheric environment to an aerobic environment. There are many cyanobacteria (such as Anabaena) that can directly fix nitrogen in the atmosphere (reason: contain nitrogenase, which can directly carry out biological nitrogen fixation), so as to improve soil fertility and increase crop production; [0003] Cyanobacteria exist in nutrient-rich water bodies, often multiply in large numbers in summer, and form a layer of blue-green and foul-smelling floating foam on the water surface, which is called "water bloom". Large-scale blue-green algae outbreaks are called "gre...
