Cleaning and disinfection of soft-shelled turtle pond

After 8-10 months of greenhouse culture, the indoor soft-shelled turtle pond has enriched a variety of pathogenic and residual bait, feces and other organic residues, so it is very important to clean up and disinfect the turtle pond. The sand in the pool had better be replaced, and the unchangeable or non-sand pool should be washed and disinfected repeatedly. Release water 10cm about 10 days before use, sprinkle it with quicklime, strong chlorine essence or chlorine dioxide in the whole pool to kill bacteria. The old greenhouse farmed for many years had better carry out space disinfection to prevent the pathogen from spreading in space. Specific can be used solid formaldehyde (41.5 grams / cubic meter), put it in the iron bucket to place briquettes on the furnace slowly heating, so that the formaldehyde gas produced after heating pervades the entire greenhouse space, playing the role of sterilization.
