Example Embodiment

[0013] Embodiment one:

[0014] In the embodiment of the present invention, sodium percarbonate is 20%, humus is 5%, polyferric sulfate is 40%, attapulgite is 20%; zeolite powder is 15%. The above-mentioned raw materials are weighed respectively according to the ratio of total weight 1Kg, sodium percarbonate is packaged separately, and other components are packaged after being mixed evenly at normal temperature. Then put the two packages into a large packaging bag and seal it, and finally pack it into a warehouse.

[0015] The action principle of each component among the present invention is as follows:

[0016] 1. Sodium percarbonate: Sodium percarbonate, commonly known as solid hydrogen peroxide, is an addition compound of hydrogen peroxide and sodium carbonate, with a molecular formula of 2Na 2 CO 3 ·3H 2 o 2 , with a molecular weight of 314.07. Sodium percarbonate produces oxygen and sodium carbonate after being decomposed with water, and its effective active content...

Abstract

This invention relates to a sediment improver for aquaculture pond. The sediment improver comprises sodium percarbonate, humus soil, poly (ferric sulfate), attapulgite soil, and zeolite powder. The sediment improver is produced by: weighing the above components, packaging sodium percarbonate alone, mixing the other components, packaging, and sealing the two packages in a big package. The net content of each big package is 1 kg. The sediment improver has such advantages as convenient usage, no environmental influence, low usage amount, rapid acting and stable effect. The sediment improver can obviously reduce the contents of harmful substances in pond bottom, improve the environmental quality of pond sediment and the living condition of aquaculture creatures, prevent diseases and abrupt death of aquaculture creatures, and increase the yield and quality of aquaculture creatures.

Description

technical field [0001] The invention relates to an agent for improving bottom quality of aquaculture ponds, belonging to the technical field of aquaculture. Background technique [0002] Since the reform and opening up, my country's aquaculture industry has developed by leaps and bounds, and it has become the only fishery country in the world where the aquaculture output exceeds the fishing output. In my country's aquaculture industry, pond aquaculture occupies a pivotal position. Most of the existing pond aquaculture adheres to the traditional aquaculture mode characterized by "dense, mixed, and round" technology, that is, a multi-species, high-density, large-scale fertilization and baiting to obtain high-yield aquaculture mode. In order to increase the aquaculture output per unit of water body, one-sided pursuit of high yield, often excessively increase water body nutrition, excessive feeding, fertilization and increase stocking density, resulting in a sharp increase in n...
