This invention belongs to the field of biological agents for
aquaculture, and discloses a compound biological pond-
cleaning agent containing tea
saponin and its preparation method. The compound biological pond-
cleaning agent of this invention comprises the following components by weight: 3-10 parts tea
saponin, 60-70 parts roe beetle root
powder, 10-20 parts
Buddleja officinalis, 5-10 parts compound microbial
powder, 3-8 parts adjuvants, and 10-20 parts carrier; the
adjuvant is a mixture of
sodium lignin sulfonate and
sodium dodecylbenzene sulfonate; the compound microbial
powder is a mixture of
Bacillus subtilis and
photosynthetic bacteria; and the carrier is diatomaceous earth. This invention combines three natural active ingredients—tea
saponin, roe beetle root powder, and
Buddleja officinalis—with suitable adjuvants and a carrier, which can expand the pond-cleaning range and has good killing or inhibitory effects on harmful organisms such as wild fish,
shrimp, crabs, and snails, as well as various pathogens. The pond-cleaning is thorough, and the raw materials are easily degradable, leaving no residue. It is
environmentally friendly and has a long-lasting effect, which is of great significance for promoting the green and
sustainable development of
aquaculture.
