Compound pond clearing agent used for culturing holothurian and preparation method thereof

Abstract

The invention discloses a compound pond clearing agent used for culturing holothurian and a preparation method thereof. The pond clearing agent is composed of tea saponin, ivermectin, spirodiclofen, phoxim, cyclohexanone, methanol, emulsifier, azone and deionized water. The preparation method of the pond clearing agent comprises the following steps: weighing all components in percentage by weight; a. dissolving ivermectin in cyclohexanone, and stirring until the solution is homogeneous and transparent; b. adding phoxim and stirring until the solution is homogeneous and transparent; c. adding spirodiclofen and stirring until the solution is clear and transparent; d. adding the emulsifier and stirring until the solution is homogeneous and transparent; e. adding azone and stirring for 3-5 minutes to obtain a solution for standby; f. mixing methanol and deionized water in the proportion of 1:1, and adding tea saponin and stirring until the solution becomes faint yellow, homogeneous and transparent; and g. adding the tea saponin solution into the solution for standby, adding deionized water and stirring at a speed of 200-300r / min until the solution is homogeneous and transparent. In the invention, the high-efficiency and low-toxicity phoxim, tea saponin, ivermectin and spirodiclofen are used jointly, thus the compound pond clearing agent has the advantages of low toxicity, no residue, less dosage and good pond clearing effect.

Description

Technical field [0001] The invention relates to a pond clearing agent, in particular to a compound clearing agent for sea cucumber breeding, and also provides a preparation method of the compound clearing agent for sea cucumber breeding. Background technique [0002] Sea cucumber is the first of the eight sea treasures in China. It is rich in protein and other nutrients. In recent years, sea cucumber farming has flourished in the northern coastal areas. The aquaculture area is expanding rapidly and the economic benefits are considerable. The living habit of sea cucumbers is to go through two sleeps, hibernation and summer dormancy. During summer dormancy, goby, sea catfish, crabs, prawns, starfish and other organisms that enter the pond will cause great harm to the sea cucumber seeds in summer dormancy. Great loss. At the same time, these predators will also eat the bait of sea cucumbers, resulting in waste of bait and reduced economic benefits. The traditional method of cleani...

Problems solved by technology

At the same time, these harmful organisms will also eat the bait of sea cucumbers, resulting in a waste of bait and a decline in economic benefits

The traditional pond cleaning method is to use a large amount of highly toxic chemical pesticides, such as fenpropathrin, deltamethrin, etc. Although these drugs can kill enemy organisms, they are highly toxic and have a long residual time, which will damage the cultured sea cucumbers and The environment has caused great harm, and it may also cause many food safety hazards
