Fertilizer and water paste for cultivating algae in pearl mussel culture pond

Abstract

The invention discloses fertilizer and water paste for cultivating algae in a pearl mussel culture pond. The fertilizer and water paste is prepared from the following raw materials in parts by weight:20-40 parts of biochemical potassium fulvate, 10-30 parts of hydrolyzed amino acid raw powder, 10-30 parts of nitrogen-phosphorus-potassium compound fertilizer, 10-20 parts of calcium magnesium phosphate fertilizer and 1-2 parts of premix. The fertilizer and water paste is suitable for pearl mussel culture. A certain amount of calcium element and trace elements are added into the raw materials ofthe nutrient water paste, and the elements can be better absorbed by matching with the complexing action of potassium fulvate, so that the requirements of pearl mussels on the elements are met, and the pearl mussels can better grow; meanwhile, potassium fulvate has a chelating effect on macroelements and microelements, so that the environment of the bottom mud can be improved, nutrient elements in the bottom mud are combined with potassium fulvate and can be absorbed and utilized by algae, the fertility in the bottom mud is gradually released, and manpower and material resources for pond desilting are reduced.

Description

technical field [0001] The invention belongs to the technical field of pearl mussel cultivation, in particular to a fertilizer and water ointment for cultivating algae in pearl mussel culture ponds. Background technique [0002] Mussels usually feed on bacteria, phytoplankton, protozoa, rotifers, small cladocerans, small copepods and organic debris in the water, and belong to filter-feeding shellfish. Artificially cultured pearl mussels mainly feed on algae in the water body , in the cultivation process of pearl mussels, according to the water color, it is necessary to input organic fertilizer or chemical fertilizer from time to time to fertilize the water, that is, to cultivate algae. At present, the fertilization and water method of pearl mussel cultivation mainly goes through the following two stages: unfermented chicken and duck manure plus chemical fertilizers ; fermented organic fertilizer plus chemical fertilizer, these two methods of fertilizer and water will cause c...

Problems solved by technology

[0002] Mussels usually feed on bacteria, phytoplankton, protozoa, rotifers, small cladocerans, small copepods and organic debris in the water, and belong to filter-feeding shellfish. Artificially cultured pearl mussels mainly feed on algae in the water body , in the cultivation process of pearl mussels, according to the water color, it is necessary to input organic fertilizer or chemical fertilizer from time to time to fertilize the water, that is, to cultivate algae. At present, the fertilization and water method of pearl mussel cultivation mainly goes through the following two stages: unfermented chicken and duck manure plus chemical fertilizers ; fermented organic fertilizer plus chemical fertilizer, these two methods of fertilizer and water will cause certain pollution to water quality to a certain extent, especially the excess of ammonia nitrogen and nitrous acid will affect the normal life activities of aquatic organisms; especially the unfermented chicken and duck manure The investment will also introduce pathogenic microorganisms into the water body, causing diseases and even death of fish and pearl mussels;

[0003] During the growth process of pearl oysters, they need to absorb a large amount of calcium ions and other trace elements to meet the growth of their shells and the growth of pearls in their bodies, and the trace elements are not supplemented in the conventional fertilization process, and pearl oysters have been cultivated for many years to form pearls. The debt of trace elements in the breeding pond will affect the later pearl cultivation;

[0004] At present, in the cultivation process of pearl mussels, due to years of unscientific input of a large amount of organic fertilizers, the pond bottom mud is polluted. The older the pond bottom mud accumulates more humus and nitrogen elements, which increases the oxygen consumption of the water body. A large amount of upturning of mud will also cause water changes, and the increase of ammonia nitrogen and nitrite will affect the breeding, so the dredging work will be increased
