Problems solved by technology

[0003] At present, conventional algae cultivators mainly compound substances rich in nitrogen, phosphorus, and organic fertilizers to promote the growth of algae in ponds, but they cannot specifically promote the reproduction of beneficial algae. If the original algae phase in the pond Harmful algae are in the majority, so it is easy to cultivate bad algae, which will affect the growth of farmed animals

Abstract

The invention relates to an algae culture agent for aquaculture, and belongs to the technical field of aquaculture. The algae culture agent is prepared from potassium fulvic acid, sodium metasilicate, ammonium sulfate, sodium humate, monopotassium phosphate and a beneficial algal solution. The algae culture agent is prepared by weighing the materials according to ratios, uniformly stirring and mixing the materials into paste, and packaging the paste, thereby obtaining the algae culture agent for aquaculture. The raw materials selected for the algae culture agent are dissolved in water at constant speed, so that the phenomenon that a pond substrate is corrupted by insoluble raw materials settled to the bottom of a pond is avoided. Meanwhile, after the sodium humate is dissolved in water, a certain water color appears, so that slow growth of algae can be controlled, and the phenomenon of stress to an aquatic animal due to rapid rise, which is caused by rapid growth of the algae, of the pH of the pond is avoided. Furthermore, the beneficial algal solution in the algae culture agent can be multiplied preferentially after obtaining proper nutrition, so that the amount of beneficial algae is effectively increased, and multiplication of harmful algae is inhibited; therefore, a better guarantee is provided for aquaculture success.

Description

technical field [0001] The invention relates to an algae cultivation agent for aquaculture, which belongs to the technical field of aquaculture. Background technique [0002] Dissolved oxygen is the most important indicator of aquaculture ponds. High dissolved oxygen will increase the conversion rate of bait, which can save farming costs; high dissolved oxygen can quickly transform harmful substances in water (such as hydrogen sulfide, nitrite, etc.); Oxygen is high, the vitality of aquatic animals is strong, it is not easy to get sick, and it can promote the growth of shrimp and crab moulting. Under normal circumstances, more than 70% of the oxygen in the pond comes from the photosynthesis of algae. During the breeding process, the dissolved oxygen in the pond is increased mainly by cultivating the algal phase of the pond. But not all algae are beneficial to aquaculture. If the unfavorable algal phase dominated by cyanobacteria (such as Microcystis, Anabaena, etc.) is cul...
