Embodiment 1

[0034] A water quality improver for freshwater aquaculture ponds, consisting of the mass fractions of the following raw materials:

[0035]

[0036] The preparation method of the potato dry residue is as follows: put the potato residue into a polyethylene container and add 0.8% sodium hydroxide solution, and mix the potato residue and the sodium hydroxide solution according to a solid-to-liquid ratio of 1:5 (w / v), After stirring evenly, soak for 30-40 minutes, then filter and take the potato dregs, dry at 65°C or air-dry naturally, so that the moisture content of the potato dregs is controlled at 9-10%, and the dried potato dregs are obtained;

[0037] Described sodium carboxymethyl cellulose is binder;

[0038] The inorganic nutrient salt composition is K 2 HPO 4 、KH 2 PO 4 , NaCl, MgSO 4 , the 4 ingredients are mixed according to the ratio of 1:1:5:1;

Abstract

The invention discloses a water quality improvement agent for freshwater aquaculture ponds and a preparation method thereof, and belongs to the field of water quality regulation of aquaculture ponds.The modifier is prepared from potato dry residue, sodium humate, zeolite powder, sodium carboxymethyl cellulose, and inorganic nutrient salts. The effect of the improver is remarkable and lasting, andthe water quality of the freshwater aquaculture pond can be effectively controlled during the high temperature breeding season, and the healthy and sustainable development of the freshwater aquaculture industry is promoted. The improvement agent is easy to manufacture and simple to operate, and can be used for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of water quality control of aquaculture ponds, in particular to a water quality improver for freshwater aquaculture ponds, and more specifically to a preparation method for a freshwater aquaculture pond water quality improver. Background technique [0002] With the increase in the output of aquaculture in my country year by year, the intensive and high-density aquaculture mode has become more and more serious in the pollution of aquaculture water and pond bottom. Aquaculture animals can only absorb about 20% to 30% of the protein in the artificial compound feed, and the rest will be discharged to the bottom of the pond in the form of residual bait and feces. At the same time, the dead bodies of algae and aquatic animals and plants in the pond also accumulate at the bottom of the pond. These organic matter not only consume oxygen in the aquaculture water through fermentation, but also pollute the aquaculture water with...
