AI Technical Summary

Problems solved by technology

Although these treatment methods have certain effects, they mainly play a role in the water body, and it is difficult to reach the bottom, so they have limited effect on increasing oxygen and improving the substrate.
Installing bottom aeration equipment at the bottom of the pond can increase oxygen at the bottom, but the investment is large and has no effect on the bottom quality, and when the pond is hypoxic, it cannot quickly increase oxygen for first aid

Abstract

The invention discloses a strong oxygenation substrate modifier for aquiculture and a preparation method thereof. The strong oxygenation substrate modifier comprises individually packaged first mixed particles and second particles, wherein the first mixed particles include 80-85 parts by weight of polymeric ferric sulfate, 10-15 parts by weight of bentonite and 5-10 parts by weight of kieselguhr; and the second particles include 10-15 parts by weight of sodium percarbonate particles. According to the invention, multiple effective components harmless to aquiculture organisms are utilized, and the components are definite, stable in effect, little in dose and capable of quickly settling to the water bottom to quickly increase the oxygen content at the water bottom and convert various harmless components, thereby creating a substrate environment favorable for survival and growth of the aquiculture organisms. The strong oxygenation substrate modifier disclosed by the invention is convenient to use, can not be affected by weather environment conditions, can quickly increase dissolved oxygen in water after being used, and especially can quickly release dissolved oxygen to prevent a suffocation accident when a pond seriously lacks oxygen.

Description

technical field [0001] The invention discloses a powerful oxygen-increasing substrate improver for aquaculture, and also discloses a preparation method of the powerful aerobic-increase substrate improver for aquaculture. Background technique [0002] Water quality management is the core of daily pond culture management. Pond bottom quality is an important part of pond ecosystem, and the state of the bottom has a decisive impact on pond water quality. Therefore, in order to maintain good water quality in the pond, the bottom quality of the pond must be well managed. In the aquaculture water body, a large amount of fertilizer deposited by excessive fertilizer and water, residual bait produced by feeding a large amount of bait, excrement of aquatic animals, etc. accumulate at the bottom of the pond, excessively consuming dissolved oxygen at the bottom of the water body, making the bottom of the pond in an anoxic environment for a long time . Pond ecology is a heterogeneous sy...
