Embodiment 1

[0029] The beer sludge used in this example comes from the sewage treatment workshop of Zhujiang Brewery Co., Ltd. The moisture content of the sludge is 80%, the organic matter content (g / kg) is 334.7; the total nitrogen (%) is 4.208; the total phosphorus (%) is 1.02.

[0030] Dry the beer sludge to a moisture content of 8-10%, seal the bag for use, and store it for a maximum of one year without odor.

Embodiment 2

[0032] Mix beer sludge (with a water content of 80%), probiotics, sugars and carriers in a mass ratio of 100:2:4:94 and place them in fermentation bags for storage. Can be placed for 60 days without smelling.

[0033] The beer sludge comes from the sewage treatment workshop of Zhujiang Brewery Co., Ltd. The moisture content of the sludge is 80%, the organic matter content (g / kg) is 334.7; the total nitrogen (%) is 4.208; the total phosphorus (%) is 1.02, the same below.

[0034] The EM bacteria adopt the "EM composite strain" of Baoding Qiwei Biotechnology Development Co., Ltd., the same below.

[0035] The sugar used is brown sugar, and the carrier used is rice bran.

Embodiment 3

[0037] Mix beer sludge (with a water content of 80%), probiotics, sugars and carriers in a mass ratio of 100:1:1:150 and place them in fermentation bags for storage. Can be placed for 60 days without smelling.

[0038] The sugar used in this example is brown sugar, and the carrier used is soybean meal.

Abstract

The invention discloses biological fish manure for aquaculture, which mainly comprises a base fertilizer, a deodorant, an activator and a carrier. After the biological fish manure is applied for 5-7 days, plankton mainly containing yellow green and drab brown alga and ovigerous females in a culturing water body are easily digested and absorbed by breeding animals, the feeding amount of the manure is reduced, and the culturing cost is saved. During the culturing, water quality is fertile, fresh, soft and clear, and the breeding animals are low in morbidity, high in rate of survival, and beefy and tender in meat quality. According to the biological fish manure, the utilization problem of beer brewing wastes is solved, the healthy and sustainable development of green aquaculture industry is promoted, the recycling economy, namely wastes are turned to be profitable, and the social and economic benefits are good.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a biological fish fertilizer for aquaculture. Background technique [0002] Currently, in my country's aquaculture industry, the deterioration of the water environment has become a bottleneck for the sustainable development of the aquaculture industry. In order to obtain a higher yield in a certain water body, people have to put a large amount of bait, fertilizer, fishing medicine, etc. into the water body to meet the requirements of fish growth and disease control. This breeding method characterized by strong feeding and heavy fertilizer increases the decomposition and transformation load of nitrogen, phosphorus and organic matter in the water body. Due to poor water quality control and management, microbial decomposition is not smooth, material circulation and energy flow in the water body are blocked, residual bait, organic residues and fish metabolites continue to accu...
