Aquaculture special-purpose fertilizer

Abstract

The present invention belongs to the field of fish cultivating technology, and is especially one kind of fertilizer specially for aquatic cultivation. The fertilizer consists of nitrogen fertilizer 75-85 wt%, phosphate fertilizer 10-20 wt% and trace elements 3-6 wt% mixed homogeneously. The fertilizer has the advantages including capacity of culturing unicellular algae in the pond, rich nutrients, no contamination to water, capacity of maintaining ecological balance, etc.

Description

1. Technical field [0001] The invention relates to a special fertilizer for aquaculture, in particular to a special fertilizer for aquaculture, which belongs to the fishery breeding technology. 2. Background technology [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-celled algae in the growing ponds to create good "water color" and transparency, often simply apply the fertilization methods in large-scale agriculture, and directly apply urea, phosphate fertilizer, ammonium bicarbonate, ammonium phosphate, etc. to the growing ponds Chemical fertilizers and fermented fertilizers; in recent years, there have been researches on the development of suitable fertilizers for ponds, but no concept of special fertilizers for aquaculture has been proposed, no clear production standards for special ...
