Problems solved by technology

For this reason, farmers usually add disinfectant to the water body for sterilization, and there is a balanced ecosystem in the water body. During the process of adding disinfectant for sterilization, the disinfectant has a strong broad spectrum and poor pertinence to germs. And it is easy to destroy the ecological balance, which is not conducive to long-term antibacterial

Abstract

The invention provides a nutritional bacteriostatic sustained-release ball for algae culture, which comprises a wrapping material, microbial powder and a nutrient medium, the microbial powder and the nutrient medium are mixed and prepared into spherical particles of 0.5-0.8 cm, the spherical particles are fermented for 5-9 days at 37 DEG C to obtain mixed balls, a binder is sprayed on the surfaces of the mixed balls, then the wrapping material and the mixed balls are mixed, and the nutritional bacteriostatic sustained-release ball is obtained. The sustained-release balls are obtained; the nutrient medium comprises a base material and nutrients; the base material comprises brown sugar, a framework material and yellow mud or sea mud; the nutrients comprise sodium nitrate or potassium nitrate, monopotassium phosphate or sodium dihydrogen phosphate, magnesium sulfate heptahydrate, calcium chloride, sodium bicarbonate, a trace element solution and a vitamin solution. The bacteriostatic sustained-release ball has the advantages of reasonable design, low cost, convenience in use and good use effect.

Description

technical field [0001] The invention relates to the technical field of algae cultivation, in particular to a nutritional antibacterial slow-release ball for algae cultivation. Background technique [0002] Algae is a kind of low-level aquatic plant, which has the significance of cultivation because of its food value and medicinal value. In the early stage of algae cultivation, fertilizers are usually applied to the water body in a one-time fertilization method, resulting in poor fertilization accuracy, and too much fertilizer affects the growth and reproduction of algae in the water body, affecting the quality of algae. As people have a deeper understanding of algae, the method of algae cultivation has also gradually changed. The current cultivation method mainly relies on experience cultivation, and the cultivation personnel continue to supplement nutrients to the water body by observing the growth of algae. However, due to the different levels of experience of the cultiva...
