Problems solved by technology

[0002] The common problems existing in the bottom of freshwater aquaculture ponds are excessive silt, many toxic and harmful substances, and easy hypoxia. With the increase of breeding years, silt enrichment, nutrient supply imbalance, soluble harmful components accumulate and cause toxicity, resulting in lack of oxygen at the bottom of the pond. Oxygen environment affects the cultured fish entering the bottom of the water body. The decomposition of organic matter in the bottom silt consumes a lot of oxygen, which makes the pond water environment prone to hypoxia, fish floating heads, and even flooding, resulting in breeding losses.

Embodiment 1

[0007] Embodiment 1: A bottom quality conditioner for freshwater aquaculture ponds, characterized in that the raw materials are composed of: 15 parts of slag ash, 13 parts of peat soil, 10 parts of carbonized straw, 13 parts of zeolite powder, medical stone 13 parts, 6 parts of humus, 4 parts of bentonite, 18 parts of decomposed farmyard manure, 2.4 parts of percarbamide, 1.5 parts of diammonium phosphate, 1.1 parts of potassium sulfate, 3 parts of gypsum powder, and the parts are parts by weight.

[0008] The preparation method of the bottom quality conditioner of the freshwater aquaculture pond is to dry the decomposed farmyard manure until the water content is lower than 16%, and respectively take slag ash, peat soil, carbonized straw, zeolite powder, medical stone, humus soil and bentonite And the fully decomposed farmyard manure after drying is fully pulverized, passed through a 60-80 mesh screen, and then the pulverized raw material fine powder is mixed with other above-m...

Embodiment 2

[0009] Embodiment 2: A bottom quality conditioner for freshwater aquaculture ponds, characterized in that the raw materials are composed of: 20 parts of slag ash, 10 parts of peat soil, 11 parts of carbonized straw, 10 parts of zeolite powder, medical stone 12 parts, 10 parts of humus, 2 parts of bentonite, 18.2 parts of decomposed farmyard manure, 2.2 parts of percarbamide, 1.3 parts of diammonium phosphate, 1.3 parts of potassium sulfate, 2 parts of gypsum powder, and the parts are parts by weight. The above-mentioned raw material components are fully mixed and stirred evenly to make particles with a particle size of 0.8 cm; the production method is the same as in Example 1, and 120 kilograms per mu of ponds are applied in ponds during use.

Embodiment 3

[0010] Embodiment 3: A bottom quality conditioner for freshwater aquaculture ponds, characterized in that the raw materials are composed of: 17 parts of slag ash, 12 parts of peat soil, 12 parts of carbonized straw powder, 12 parts of zeolite powder, medical stone 12 parts, 8 parts of humus, 3 parts of bentonite, 16.7 parts of decomposed farmyard manure drying, 2.3 parts of percarbamide, 1.4 parts of diammonium phosphate, 1.2 parts of potassium sulfate, 2.4 parts of gypsum powder, the parts are parts by weight, The above-mentioned raw material components are fully mixed and stirred evenly to make particles with a particle diameter of 1.2 centimeters; the preparation method is the same as in Example 1, and 150 kilograms of ponds per mu are used in ponds.

[0011] Beneficial effects: Sprinkle the pond bottom conditioner granules in the pond, use 100-150 kg per mu, the bottom conditioner granules will settle in the pond bottom, significantly reduce the content of harmful substance...

Abstract

The invention discloses a freshwater aquaculture pond sediment conditioner. The conditioner is characterized in that slag, turfy soil, charred straw, zeolite powder, medical stone, humus, bentonite, decomposed farmyard manure, percarbamide, diammonium phosphate, potassium sulfate and gypsum powder are prepared into the aquaculture pond sediment conditioner; after the conditioner is used, the content of hazardous substances in sediment is remarkably lowered, the content of nitrite, hydrogen sulfide and the like in the pond sediment is lowered, release of effective ingredients is promoted, the content of organic matter and nutritional elements such as nitrogen, phosphorus and potassium in the sediment is increased, environmental conditions of the pond sediment are improved, nutritional elements and nutrition coordination substances needed for a water environment are added, and the effects of improving the sediment, enhancing fertility and removing toxic substances are achieved. The conditioner has the advantages that raw material resources are rich, the preparation process is simple, application is convenient, production cost is low, and toxic and side effects are avoided.
