Aquatic plants should be disinfected before cooking cold dishes. What is the reason?

Disinfection and sterilization of hydroponic plants means cleaning and disinfecting moldy rhizomes to make them grow and develop normally. There are many disinfection products for hydroponic plants, such as mancozeb, triadimefon, thiophanate and agricultural streptomycin. Different drugs have different use experiences, so it is necessary to follow the instructions to prevent burning plant roots. Generally, the whole disinfection and sterilization process is soaked for about half an hour. After soaking, plants must be dried for 4-6 hours. After drying the roots, they should be placed in a hydroponic container. The first function of drying is to thoroughly sterilize the roots, so that the sterilized aqueous solution can be volatilized to avoid affecting the solution. Use hydrogen peroxide. Pour a bottle of hydrogen peroxide disinfectant (3% hydrogen peroxide) into mineral water or boiled cold water, stir well and put it in green plants.

Can provide O2, kill two birds with one stone. Do not put culture solution, it will pollute the environment and water quality. You'd better remember to sprinkle more water on the leaves. After cleaning the pond, it should be disinfected. The pond can be disinfected with quicklime powder and bleaching powder solution. Our farms here all choose quicklime powder, and the actual effect of quicklime will be much higher than that of bleaching solution. The usage of quicklime is calculated in square meters in English, and disinfection and sterilization also need to be done once a year. The bottom should be changed about a week before the shrimp seedlings are released. Penaeus vannamei has high requirements for water bodies, which need to be well controlled, and the pH value of some water bodies needs to be accurately adjusted. Cultivating a pool of good water is very important for aquaculture. Keep the feeding amount. Too much food will sink into the bottom of the water and deteriorate, endangering the water body. Too little feeding will endanger the growth of shrimp, especially in summer, and the feeding quantity and frequency should be reduced.

When it is hot, it is easy to lack oxygen in rainy days. If possible, it is best to assemble an oxygen pump to learn and exchange knowledge about Penaeus vannamei or aquaculture. Disinfection and sterilization of ponds is a crucial whole process of aquatic product culture, which not only relates to whether aquatic products can have a good living environment, but also plays an obvious role in preventing and controlling aquatic products' problems and diseases and pests. The commonly used disinfectants for pond disinfection and sterilization mainly include lime powder, bleaching powder solution and chlorine dioxide. Among them, the application of quicklime is the most extensive at present, and the dosage is also the largest.

Quick lime disinfection: disinfection with quick lime can also be carried out in two ways: dry disinfection and wet disinfection. For newly dug ponds, wet disinfection is recommended. Common pool cleaning drugs mainly include quicklime powder, tea seed powder, trichlorfon and bleaching powder solution. Different drugs have different disinfection and sterilization levels, so it is necessary to pay attention to the integration of feeding objectives and the selection of pond sediment. There are two ways to clean the pond: dry pond cleaning and water cleaning, but personally, dry pond cleaning is better.
