Problems solved by technology

The dead algae and organisms will be oxidized in the water again, and the water body will become very smelly at this time, and the water resources will be polluted and cannot be reused
[0004] At present, there are two main ways to control the large-scale outbreak of cyanobacteria caused by eutrophication of water bodies. One is to control the entry of nitrogen, phosphorus, potassium and other elements into the water body. This method cannot be effectively implemented in a short time; the other is to control the cyanobacteria. Carry out salvage and process through some channels, and control in the middle link to avoid continuous deterioration of the subsequent water body

Embodiment 1

[0028] 1) Pretreatment of raw materials: The raw materials are salvaged and separated from Dianchi Lake algae-water separation station, and discarded tobacco stems and tobacco powder after flue-cured tobacco. 50 parts of tobacco stems and 100 parts of tobacco dust. Use the discarded tobacco stems and tobacco dust after flue-cured tobacco to adjust the carbon-nitrogen ratio of the raw materials to about 30:1, and then use GaCO 3 Regulate pH value to 6.5, moisture content is adjusted to (weight percentage) 50%;

[0029] 2) Mixing: Add a fermentation agent with a total weight of 3‰ to the above pretreated materials, mix well and then compost and ferment in the fermentation workshop; the fermentation agent is produced by Yunnan Yunye Fertilizer Co., Ltd. The patent No. 201310055173.9 is an organic fertilizer fermentation agent. This organic fertilizer fermentation agent is developed and produced by Yunnan Yunye Fertilizer Co., Ltd. for tobacco waste as a fermentation substrate. It...

Embodiment 2

[0034] 1) Pretreatment of raw materials: The raw materials are cyanobacteria in Dianchi Lake salvaged by algae-water separation station and separated from algae-water, tobacco stems and tobacco powder discarded after flue-cured tobacco. 60 parts of tobacco stems and 80 parts of tobacco dust. Use the discarded tobacco stems and tobacco dust after flue-cured tobacco to adjust the carbon-nitrogen ratio of the raw materials to about 35:1, and then use GaCO 3 Regulate pH value to 7.5, moisture content is adjusted to (weight percentage) 55%;

[0035] 2) Mixing: Add a fermentation agent with a total weight of 5‰ to the above pretreated materials, mix well and then compost and ferment in the fermentation workshop; the fermentation agent is produced by Yunnan Yunye Fertilizer Co., Ltd. The patent No. 201310055173.9 is an organic fertilizer fermentation agent. This organic fertilizer fermentation agent is developed and produced by Yunnan Yunye Fertilizer Co., Ltd. for tobacco waste as a...

Abstract

The invention relates to organic fertilizer containing blue algae and a preparing method of the organic fertilizer. The preparing method comprises the following steps that firstly, raw materials are pretreated, wherein, by weight, 50-60 parts of Dian Lake blue algae, 50-60 parts of tobacco stems and 80-100 parts of tobacco residues are added, then GaCO3 is used for regulating the pH value to 6.5-7.5, the moisture content is regulated to 40-60% by weight, and the tobacco stems and the tobacco residues are waste materials generated after tobacco is cured; secondly, the materials are mixed, a fermenting agent accounting for 0.3-0.5% of the total weight of the materials is added for compost fermentation until fermentation curing is completed, and the obtained materials are screened and then can be prepared into the powdery organic fertilizer containing the blue algae; particle organic fertilizer containing the blue algae can be produced through granulation and screening. By means of the organic fertilizer containing the blue algae and the preparing method of the organic fertilizer, the problems that a large quantity of blue algae grow and cannot be effectively disposed are solved, the organic fertilizer contains rich organic matter and other active factors and thus achieves great effects on crop production and income increasing and soil improvement, and great benefits on ecological environmental protection and development of green organic agriculture are achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic fertilizer containing cyanobacteria and a preparation method thereof. Background technique [0002] One of the most important problems in the global water environment at present is the increasing eutrophication of water bodies. In my country, more than three-quarters of the lakes and rivers have experienced varying degrees of eutrophication, especially Chaohu Lake, Dianchi Lake, and Taihu Lake. The seawater quality of Grade VI and inferior Grade VI accounts for 30% of the coastal waters. Eutrophication refers to the fact that a large amount of nitrogen, phosphorus, potassium and other elements are discharged into the surface water body with slow flow rate and long renewal cycle, which makes algae and other aquatic organisms grow and reproduce in large numbers, and the rate of organic matter production is far faster than that of water. The rate of consumption, the ...
