Modifying agent for bottom material of pond for breeding aquatic products

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...

Problems solved by technology

However, the mechanism of action of the adsorbent is mainly a physical method, and its adsorption effect is obviously affected by environmental factors, and the amount of use is relatively large. Generally, the amount used per mu of water surface per meter of water depth is 5-15 kg

However, the use of microbial preparations is greatly affected by factors such as the type of microorganisms, their activity, and dissolved oxygen in water, and the effect is slow and unstable.
