Problems solved by technology

Povidone-iodine solution is used in crab ponds, which can improve water quality, kill harmful bacteria, molds and spores thereof in the water body, and have a strong inhibitory effect on Vibrio, Aeromonas hydrophila, and Edwardsiella; but The water body of the pond is complicated, and the existing povidone-iodine solution has disadvantages such as instability, short action time, and large dosage
At the same time, crabs belong to crustaceans, and they shed their shells several times during the growth process. During the shelling period, they are weak in constitution and low in immunity, and are prone to infection of bacteria and other diseases. The drugs of topical disinfectants will increase the stimulation and cause the shelling period to be prolonged. Affect normal breeding management

Abstract

The invention discloses a compound povidone-iodine solution for a crab shelling period and a preparation method of the compound povidone-iodine solution, and belongs to the technical field of aquaticproduct disinfection. The compound povidone-iodine solution provided by the invention is prepared from the following components in percentage by mass: 10 to 50 percent of a povidone-iodine solution, 1to 20 percent of 20-hydroxyecdysterone, 30 to 45 percent of a solution A and 10 to 35 percent of a surfactant, wherein the solution A is prepared from the following components in percentage by mass:20 to 50 percent of rheum officinale, 10 to 35 percent of cortex phellodendri, 10 to 35 percent of radix scutellariae and 20 to 50 percent of purified water. According to the compound povidone-iodinesolution provided by the invention, the disinfection effect of the povidone-iodine solution is not influenced, and meanwhile, the synchronous shelling rate of crabs can be increased, the immunity of soft-shell crabs in the shelling period of the crabs is improved, autogenous residual food is avoided, the effective iodine content is high, and the stability is better.

Description

technical field [0001] The invention belongs to the technical field of aquatic product disinfection, and relates to a compound povidone-iodine solution used in the shelling stage of crabs and a preparation method thereof. Background technique [0002] With the accelerated development of crab farming, people have higher and higher requirements for the quality of crabs that come out of ponds and enter the dining table, and people are pursuing pollution-free green food. In the field of aquaculture, disinfection drugs are an important factor that directly affects the quality of aquatic products. In the process of crab farming, the research on efficient, low-toxic, environmentally friendly and healthy disinfection drugs still has a long way to go. [0003] In the existing crab breeding process, the frequently used, environmentally friendly and safe disinfectant is povidone-iodine solution. Povidone-iodine solution is used in crab ponds, which can improve water quality, kill harm...
