Substrate improver for fishery industry and preparation method of substrate improver

Abstract

The invention relates to a substrate improver for the fishery industry. The substrate improver is prepared from 50% of sodium percarbonate, 40% of zeolite powder, 5% of ferrous chloride and 5% of carboxymethyl cellulose. A preparation method of the improver comprises steps as follows: 1000 kg of raw materials are weighed in percentage by weight; ferrous chloride or ferrous sulfate with weight thesame as that of ferrous chloride is added to 150 L of water and dissolved, and a ferrous chloride solution is obtained; the obtained ferrous chloride solution is mixed with the zeolite powder, and a mixture is sufficiently stirred and dried; the dried ferrous chloride and zeolite powder mixture is sufficiently mixed with sodium percarbonate and carboxymethyl cellulose in sequence and uniformly stirred, and preforming treatment is performed. The substrate improver and the preparation method have the beneficial effects as follows: the cost is lower, the oxidizing ability is strong, the application effect is remarkable, the action time is short, the probability of causing acute injuries on cultured species is low and the like.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fishery substrate improver and a preparation method thereof. Background technique [0002] Nowadays, aquaculture practitioners are more and more pursuing high yields. Therefore, the stocking density per unit area or volume of water body is also increasing, which means that the amount of feed added per unit area or volume of water body is also increasing, which further causes In addition to the deterioration of water quality in the breeding process, there is also the problem of deterioration of the bottom of the earthen pond. Whether it is the deterioration of water quality or the deterioration of the bottom, it will have a very adverse impact on the breeding objects, and even endanger the lives of the breeding objects. [0003] For the deterioration of water quality, it can be improved by changing water or adding water quality improver; for the deterioration of bottom qual...
