Fertilizer preparation special for aquaculture

Abstract

The invention relates to a fertilizer special for aquaculture, in particular to a fertilizer preparation special for aquaculture, and belongs to an aquaculture technology. The fertilizer preparation is prepared from, by weight, 75-85% of nitrogenous fertilizer, 10-20% of phosphatic fertilizer and 3-6% of trace elements through stirring and even mixing. The fertilizer preparation has the advantagesthat by means of the fertilizer preparation, floating unicellular algae are cultured in a cultivation pond, the water color and transparency represent that the water is rich in nutrient, and ecological balance of the pond is achieved.

Description

technical field [0001] The invention relates to a special fertilizer for breeding, in particular to a special preparation fertilizer for aquatic product breeding, which belongs to the fishery breeding technology. Background technique [0002] Domestic and foreign studies on the nutrient elements of planktonic single-celled algae are mainly used in the cultivation of bait organisms in the breeding process of aquaculture animals. Fertilize and cultivate planktonic single-cell algae in the grow-out pond to create good "water color" and transparency, often simply apply the fertilization method in large-scale agriculture, and directly apply urea, phosphate fertilizer, bicarbonate, phosphoric acid, etc. to the grow-out pond Chemical fertilizers and fermented fertilizers. In recent years, there have been researches on the development of suitable fertilizers for growing ponds, but no concept of special fertilizers for aquaculture has been proposed, no clear production standards for...
